Principles of the battery

Filed under: Battery tips — Tags: , , — todaybattery @ 8:24 pm

In cell chemical chemical energy directly into electricity by the battery is carried out within the spontaneous oxidation,  rechargeable laptop battery  reduction and other chemical reactions the result of the reaction was conducted in two electrodes. Negative active material of the more negative potential and an agent of the stable reduction in the composition of electrolytes, such as zinc, cadmium, lead active metals and hydrogen or hydrocarbons. Positive active material for a more positive potential on the composition of the electrolyte of a stable oxidizing agent as manganese dioxide, lead dioxide, nickel oxide and other metal oxides, oxygen or the air, halogens and their salts, oxygen-containing acid and its salts etc.. Electrolyte is a good ionic conductivity materials such as acids, alkalis, saline, organic or inorganic non-aqueous solutions, molten salts or solid electrolytes. When the external circuit disconnected,  dell inspiron e1505 battery although there is potential difference between the two poles (open circuit voltage), but there is no current, stored in batteries are not converted to chemical energy into electrical energy. When the external circuit is closed, the two electrodes under the effect of potential difference there is current flowing through the external circuit. The same time, the battery inside the electrolyte are not due to free electrons, charge transfer must be accompanied by two poles of active material and electrolyte interface, the reactions of oxidation or reduction, and reagents and reaction products of mass transfer. Charge transfer in the electrolyte, but also by the migration of ions to complete.  hp f4486b battery Thus, in the normal transfer of battery charge and the process of mass transfer is to ensure that the conditions necessary for normal production of electricity. When charging, the battery inside the transmitter power and direction of mass transfer and discharge exactly the opposite reaction of the electrode must be reversible to ensure the opposite direction to the mass transfer and mass of normal electrical processes. Therefore, the electrode reaction is reversible, a necessary condition for the batteries. Reaction of the Gibbs free energy (coke) F is the Faraday constant = 96,500 basis = 26.8 ampere-hour n the equivalent number of the cellular response. It is the reaction of the battery and the emf of the battery between the basic thermodynamic relations, but also calculate the energy conversion efficiency of cells of the basic thermodynamic equation.  compaq evo n410 battery Indeed, when current flows through the electrodes, the electrode potential must deviate from the equilibrium thermodynamic potential of the electrode, a phenomenon known as polarization. Current density (electrode surface unit adopted by the current), more polarization worse. Polarization is caused by the energy loss of the battery of important reasons. Polarization for three reasons: ① from the cells caused by different parts of the polarization resistance is called Ohm polarization;  sony vgp-bps5a battery② electrode - interface layer caused by electrolyte charge transfer blocked the process of polarization is Name polarization activation; ③ electrode - electrolyte interface layer caused by the slow mass transfer of polarization is called concentration polarization. Reduce the method of polarization is to increase the reaction zone to the electrode, which reduces the current density, increasing reaction temperature and improve the catalytic activity of the electrode surface.

Filed under: Battery tips — Tags: , , — todaybattery @ 7:44 pm

The U.S. Department of Energy Lawrence Berkeley (Lawrence Berkeley) National Laboratory in October 2009, published in the United States set the cost of the report of photovoltaic solar cells, rechargeable laptop battery   research has pointed out: From 1998 to 2008, the average cost of these systems has decreased by over 30%. In 2008, the cost has dropped more than 4%.
A reported that the recent decline in costs, mainly photovoltaic modules cost reduction results.
From 2007 to 2008 set-up cost reduction marks the trend of the previous three years, during this period, with the United States and the rapidly expanding global PV market, the price of add-on costs pressurized module,   dell e1505 battery  the industry of solar energy expansion of manufacturing capacity and the global financial crisis was located in 2008, this dynamic evolution, driving down the price of the entire module.
In contrast, between 1998 and 2007, the decrease in costs is mainly due to non-module costs, as labor costs, management costs, the cost of the inverter and balance system.
Studies have shown that between 1998 and 2008 installed in 16 states, there are 52,000 grid-connected photovoltaic systems, the survey found, with an average cost of installation (in real 2008 dollars) from 1998 U.S. $ 10.80 / W to 2008 to U.S. $ 7.50 / W, the average fell 0.30 U.S. dollars / W.
As time passes, small-scale photovoltaic systems,  hp f4812a battery if applied to households with small-scale power systems for photovoltaic power generation, the largest cost reduction. In addition, in 2008, constructed a small residential photovoltaic installation costs have emerged as the size of the increase in cheaper, less the size of an average 2KW 9.20 U.S. $ / W while the 500 ~ 750KW system to large commercial scale to an average of U.S. $ 6.50 / W.
Different states, installation costs are not the same as in 2008 and the installation of the system were smaller than 10KW, sony vgp-bps2 battery  cost flat fee of Arizona as low as U.S. $ 7.30 / W, followed by California, the average installation cost is 8.20 U.S. dollars / W higher for the Pennsylvania and Ohio, for U.S. $ 9.90 / W.

The rapid technological advances or a super capacitor to replace the lithium-ion battery

Filed under: Battery tips — Tags: , , , , — todaybattery @ 7:55 pm

So far the industry has decided that lithium-ion rechargeable laptop battery for electric cars is still the primary means of energy reserves, but now, several companies have begun to consider using a super capacitor (ultracapacitor) lithium -ion battery products as additional sound equipment. South Korea will be an electronics company Neescap Tuesday claimed that 9 million dollars will be invested to develop its systems for power transmission and consumer electronics with super capacitor (ultracapacitor) the ability of the product.

In the U.S., capable of product design and manufacture of super-capacitors and electrolyte materials, required for companies GrapheneEnergy, EnerG2 and Ioxus 3. Another EEStor companies by VCs KleinerPerkinsCaufield & Byers as the background, now the company has signed an electric car company Zenn super-contract to supply capacitor.

The more traditional batteries, ultracapacitors can store electricity much. So at home Rechargeable (plug-in) for electric vehicles, such capacity can serve as devices of engine power alone, but must be used in conjunction with fuel cells. On the other hand, dell td347 battery,dell u4873 battery the supercapacitor is also equipped with faster release energy stored in the ability of diarrhea. In addition, the capacitor charging time is very short, only takes a few seconds or minutes of time will be able to complete the charge, but charge several times the performance will not be reduced.

The consumer electronics capacitor products have been used in digital cameras and other occasions, so need momentary flash high-energy input of the device provides the energy supply. According to experts, super critical issues for the future is how to increase the operating voltage of the capacitor so it can be in the high voltage environment.

According to engineers Ioxus said, the supercapacitor energy is environmentally friendly, a good supplement can make batteries, fuel cells, solar or wind energy, food would be more perfect. At the same time, the capacitor used in the production of materials are also very environmentally friendly, the prices that some are more easily accepted.

Super capacitor technology, the orientation of future development:

Massachusetts Institute of Technology engineers in computer electronics JoelSchindall said that in the coming years, the super capacitor storage energy will be a qualitative leap. The current rate products super capacitor discharge is 10 times that of traditional batteries,  hp f2024b battery  while the storage of energy in the volume under the same conditions, only the last 5%.

He says: “charge super-capacitors and unloading of the prevalence of some great occasion, as Brake Energy Recovery System-brake type (ie, five series of F1 CCAV all day nagging system host Coles), This ability is very easy to use. Of course, this product is currently not a large scale to replace the batteries. ”

Over the past five years, Schindall led the research team studied the super capacitor in the storage component of energy - raw porous carbon replaced by another matrix component conductive carbon nanotubes storage. Earlier this year, they have also established a FastCap this company for the commercialization of research results.

Schindall says the super capacitor storage energy of the product will eventually reach about 25% of the battery. Currently, Massachusetts Institute of Technology developed nano-materials, storage of energy has reached twice the level of carbon materials. The next month, sony vgp-bps2 battery  he led the research team will be showing the kind of capacity energy storage is five times more activated carbon products.

IMEC, Belgium will be increased efficiency monocrystalline silicon solar cells to 7.5%

Filed under: Battery tips — Tags: , , , — todaybattery @ 7:51 pm

Belgian research institute IMEC has announced the trial in the thickness of the active layer as thin as 10μm silicon solar cells, but also received 7.5% of energy efficiency. Reduces the thickness of the new laptop battery to reduce the amount of silicon can be said that the development of high efficiency solar cells a step forward.
IMEC, before they are committed to the achievement of silicon thin film crystalline solar cell technology issues. Prior to that, solar cells in monocrystalline silicon is equal to or greater than the thickness of 150μm, must make a lot of silicon. This reduces not only the thickness but also by the growth of the rule of law in the layer of silicon crystals, and therefore did not produce cutting debris, and can significantly reduce the amount of the benefits of silicon.
However, if you only reduce the thickness of the case, now there are only 1 ~ 2μm thick amorphous silicon solar cells. However, the efficiency of solar cells in amorphous silicon on a single node where the limit is 6 ~ 8%.
The production of solar cells is the following: the adoption of post-treatment to be part of the glass for crystallization of the glass ceramic substrate (IMEC) to form a thin layer of crystalline silicon species, and therefore, in its top so that the activity of monocrystalline silicon layer epitaxy (epitaxial) growth. Obtained a slightly higher yield than the 7.5% energy efficiency of solar cells in amorphous silicon, but is expected to slightly adjust the structure of the electrode IMEC can be more than 9%. In addition, dell x300 battery reflection “Light and light sealing structure has not yet been any improvement. If you include these improvements are expected to 5μ ~ 10μm thick with cell activity in crystalline silicon solar to over 15% efficiency (IMEC).
IMEC said: “In the long term we hope to develop the method without the need for epitaxial growth, which further reduces costs.” The agency has tried to adopt an annealing process of porous silicon (sintering) METHOD prototype solar cells. Achieved an efficiency of 2.6%.

If the battery electric vehicle price reduction or universal access to

Filed under: Battery tips — Tags: , , , , , — todaybattery @ 7:47 pm

In the development of electric cars and rechargeable batteries, has become increasingly active cases, there is a problem become a hot spot: If the price of the battery, rechargeable laptop battery as expected, the decline of the industry popularity of electric vehicles in the next round, the car will become and the “personal” computer of the same product? If so, the Japanese will not like the Japanese PC manufacturers have the same problems?
For example, “Nikkei Manufacturing” magazine in 2009, edition of 9 special edition of “the truth of electric vehicles,” he predicted that the industrial structure of electric vehicles would, like personal computers, flat screen televisions and other appliances digital home buying parts from outside like the rest of the assembly “level of division of labor” Consistent with the standard parameters of manufactured goods, “normalization” and the major trend. May finally fell in the homogenization of the competition, and the outbreak of low-cost competition of attrition.
Europe and the manufacturers of the United States and to normalize the level of division of labor is the most enthusiastic. In May 2009, dell td347 battery  held in Norwegian electric vehicle symposium “EV24″ Magnastile Austria (Magna Steyr Fahrzengtechnik) is presented for combining a variety of standardized modules topology (connectivity models) programs. It’s like shows such as drive motors and regenerative devices, storage devices for electricity, charging devices, the module should be how to achieve the best connection method of vehicle standards electrical performance specifications. “As long as standardized modules to buy, if automakers can produce cars.”
Such as “computer” or “Lego” combination of modules, like the idea of manufacturing cars and tried for a long time, did not start with electric vehicles. For example, the German Daimler (Daimler) (then MCC) in the early 90s of last century began in France Hambach factory in a small car “Smart” car, 90% are seven suppliers module assembly and Cheng. Subsequently,  under the module production has become increasingly active Nissan and other manufacturers have built a production line modules as auxiliary line, but the entire automotive industry does not seem Module external supply, the implementation of the Industry Division range of tasks between the level of big tips.
Because from the outside but also to increase the component type module procurement, reducing the proportion of overall use, leading to higher costs, especially for the Japanese automotive industry . To this end, the motor companies and implementation of optimizing internal and intra-group outsourcing more difficult.
Outsourcing to reduce the difficulty of the need to standardize the interface between modules, so that mass market compatible with the module, and create an environment can be free to buy assembled. To this end, vehicle manufacturers, component manufacturers must master a considerable part of the initiative within the module to add run-in element to the module as a unit to improve the degree of standardization. However, as noted above, hp f4486b battery  the Company (Group) were the original module has been optimized, so hard to achieve these objectives. In addition, the mechanical parts in the high proportion of this module, three-dimensional measurements and significant differences in physical factors can not be completely performance packaging technology, the module may even have run between elements residues.
Of course, even if the run-in element residual, outsourcing, and also the level of division of labor could be made. For example, the automotive industry in China, it has taken outside the parts is not compatible, forced its combination of car manufacturing. However, the existence of such an act of combining safety, environmental protection and other vehicles performance does not meet the issues of user needs.
Compared to fuel vehicles, electric cars of different cars in a “personal computer” already have the disease. With the increase in the proportion of electronic components and digital developments in the elements of the module to add run-packaging technology will become increasingly simple. When the semiconductor to absorb run-element standard products compatible products will increase as the completion of degree, demonstrating the benefits of outsourcing.
Here “Digital-run packaging elements of” LCD TV as a contrast even easier to understand. In the manufacture of LCD TV, Japanese companies such as vertically integrated firms were self-produced LCD panels, LCD driver IC, image processing LSI and other components or buy custom products in the design solution components of addiction. But it was too early, sony bps9 battery the Taiwan MediaTek (Media Tek) and other professional image processing LSI manufacturers have emerged and have started using digital control technology to support a range of LCDs with a parameter configuration table. Customers need only refer to table settings, you can easily find the best match with the adoption of configuration items. Since then, integrated LCD driver module LCD panel and image processing LSI-pass flow of supplies on the market gradually, even the new Chinese manufacturers, as long as the purchase of these basic components, the same map can be easily assembled on LCD TVs. This makes LCD televisions tend to most of the price all the way sunk.
Electric cars are likely to suffer the same fate. Previously mentioned, “the Nikkei to create ’special edition introduced the item 9 to manufacturers of motor vehicles:” Even if it is installed in motor vehicles is too large can also be adjusted by controlling the power ” . This means that in the development of general skills, power and other basic components of standardization and compatibility will be easier, outsourcing should achieve.
In fact, Norway Think Nordic was announced in May this year, sales of foreign control of electric motors and lithium-ion rechargeable battery, apple a1012 battery  control unit power (DCS) decision. Customers can purchase ECPs company would be a variety of motor and lithium-ion rechargeable battery choice of components to produce electric vehicles. In addition to PKU, this decision may also promote the basic components - motors and rechargeable batteries, the external supplies.

Nissan Motor will be listed in the 2010 set of electric vehicle (EV) “green leaves” on the use of solar cells. Expected after the back-end roof spoiler (RearSpoiler) configured on solar panels to complement the equipment of vehicles of current consumption. gd761 battery The solar cells will begin with a certain level models. The company will be the 41st Tokyo Motor Show (October 24, 2009 ~ November 4 open to the public) on display at Green Leaf.
Nissan has green leaves on the mobile phone 3rd generation is equipped with a communication module using the state information module of vehicles can be uploaded to the data center. Users can also carry mobile phones to access a website dedicated to identify vehicles equipped with lithium-ion rechargeable battery is left, or start using a mobile phone before driving the vehicle air conditioning. But to achieve these functions, even in the car to stop traffic situations, dv4000 battery it is also part of the system required vehicle equipment was in operating condition and that cars can be received via phone users laptop to send the request. The companies formed by the green leaves of the vehicle is equipped with solar panels, devices using solar cell vehicle to consume additional power to prevent life shortening.
The reason why the roof did not choose to configure the position spoiler solar panels because it is easier to install the production line. Installed on the roof, then the needs of larger operations, if we adopt this system must be installed in accordance with solar cells on the spoiler attached to the body.

Hybrid electric vehicle battery is its biggest challenge

Filed under: Battery tips — Tags: , , , , , — todaybattery @ 7:54 pm

Energy saving auto emission has become the driving force behind the development of automotive electronics, with the increasing scarcity of oil supply and growing pollution of the environment, electric vehicles such as electricity powered vehicles, with energy savings and enjoy protection of the environment becomes a concern for the industry focus. However, even if the electric car has many advantages, but it is a time can not replace the traditional gas powered model, so that the new hybrid electric vehicle is clean with industrialization and commercialization of most models promising. However, batteries, cost, reliability, longevity, a more complex requirements of devices of high power voltage for automotive manufacturers and many other problems facing many challenges.
Infineon Technologies (China) Limited companies in the automotive electronics, Senior Marketing Engineer Cao Yu said: At present, the main challenges of hybrid cars from two aspects: one is the power systems and traditional electrical systems for coordination, the other is the need for cost control conditions to meet the requirements of automotive electronics reliability of complex application environments.
Cao Yu: Hybrid cars as a major challenge lies in the traditional power systems and electrical systems for coordination.
Fairchild, senior manager of the global automotive, Hans-PeterHoenes believes that hybrid vehicles the main design challenges are based on a very low cost to create a very complex and yet highly reliable systems.
“Electric cars can be divided into three categories: hybrid, fuel cell and electric vehicles. Electric because there is a universal problem - battery, batteries because of existing problems, the future may be the production possibility Mass The most important is the hybrid. than a hybrid engine with conventional technology, an increase in three parts, one vehicle control, 2 battery management, and the third motor control. Freescale’s Automotive Electronics Engineering Manager for China, said Xiao Kang Dun.
Xiao Kang Dun: The battery technology is the key to hybrid cars, batteries are the cost of the vehicle 1 / 3 of the foregoing.
Hybrid electric vehicle is further divided into light (micro) mixed with full hybrid vehicles, the challenges they face are different.
Light mixed with the various challenges facing the entire mixed
Cao Yu analyzed system of micro-mixing and full-hybrid system in the system are structurally very different, it is more than the system of electric capacity, hp 371785-001 battery  the percentage of the value of the difference is important that quantitative changes in the structure caused by vehicles. Micro-hybrid systems in general to achieve start-stop function, the whole hybrid system, does not power the engines of vehicles in the case still has some stamina. Because the system greatly increased the degree of coupling, the complete structure of the hybrid system is more complex and more challenges in the design.
Hans-PeterHoenes were analyzed for light hybrid vehicles, the chassis (the basic design) is still the traditional automotive design, usually in a normal car on the integration of hybrid characteristics. As the chassis (the base design) design has been fixed, the additional needs of all systems must be able to meet demand. However, this is not always the best technical solution, so far the biggest challenge in this regard is the integration of mechanical and electrical integration. In other words, the minimum space requirements for the design. As for the full use of hybrid cars, the whole design needs to change, not just the powertrain, chassis and even had to move forward and is optimized for mixed. A good design should be designed around the driveline of the car,  sony vgp-bps9 battery  while the traditional curriculum is designed for cars, but the engine placed in the “somewhere”. This is a complete change in the concept of design thinking, because the drive has been decided, or at least strongly influence the shape and appearance of the vehicle.
“The design work is facing the biggest challenge is the lack of transmission of high power electric high pressure (high pressure high-powered engine power) has extensive experience of Automotive Engineers. Because of the conditions and Cars are different, so even in the field of industrial drives and experienced Senior Consultant can provide assistance is very limited. Hoenes said. Fairchild was not only a discrete energy technology, and the gate driver IC such as. This applies not only to low voltage, but also covers the full range of voltage up to 1200V. This ability to integrate the module allows customers to receive a fully tested to optimize the power level, can solve many problems associated with the interaction between design problems and parasitic device.
Motor Control Challenges
In motor control, Cao Yu stressed that the main difficulty is the need to achieve self-reliability requirements level, and must take into account the cost of implementing this law. Also need to consider the system of record-high power caused by electromagnetic interference and noise effects. If you use the device of industrial quality, although the initial period of no major problems, dell latitude d430 battery  but as time passes, accompanied by a device designed to produce failure, the seller will give you the image and reputation has brought incalculable loss “, which is why we recommend the use of devices for automotive, effectively guarantee system of the vehicle lifecycle, reliable operation. “he said.” As the world’s leading supplier of power devices, Infineon has a depth of experience and many experts team, to better understand the specific needs of customers, helping customers to find, even those hidden in application requirements within the system details.
Infineon offers leading industry suppliers of HP1 high power density of automotive-grade module (hybridpack1) & HP2 (hybridpack2) with ultra-small size, the systems most relevant automotive constraints of space. HP1 weight 485g (72×140x17mm) 3 half-bridge in-one design, 650V400A maximum drive capacity for less than 20-30kW motors. HP2 (106.5×48.5×20.5mm) the weight of 1250g, is more directly based on a particular water-cooled thermal design to meet the 80-100KW Module 650V800A motor applications.
Microchip Automotive Automotive Products Group Marketing Manager, Chan Chung-yan, the view that: “In the hybrid vehicle, motor control for steering control, and cooling the battery and other key subsystems is critical . Brushless DC (BLDC) motors because of their small size, control and high performance The widely used. brushless DC motors are increasingly used to remove the belts and hydraulic systems to provide additional functionality and improved mileage. magnet costs continued to decrease and control of brushless DC motors electrical devices necessary to continue to reduce, leading to more and more cars, power level is also increasing. ”
Chan Chung-yan, then explained, brushless DC motors are usually controlled by one or more of the rotor position sensor used in conjunction with, because their electrical excitation must be synchronized with the rotor position. For the cost, reliability and packaging, mechanical, especially if the engine needs to be immersed in a fluid, preferably in the case of a brushless DC motor sensorless Running - that is, without the operation of the detector. Sensorless motors cost less because it does not require sensors, but the driver is more complex. Sensorless Motor in Hybrid Electric Vehicle Battery cooling system has excellent performance, this time, do not need to start and stop the engine. “Designers of embedded automotive systems meet the changing environment, the need to develop a cost-effective solution that respects the environment. Low-power micro-controller is an important mechanism to meet the demanding needs, which may increase the cost of reduced system reliability in a small package to fit a smaller space than board, and no external components. In addition, for the socket, software and peripheral compatibility with the architecture of microcontroller provides designers a great flexibility, allowing them to reduce the costs and reduce development time. Microchip Technology offers a variety of microcontrollers and DSC, to meet the challenges of demand for hybrid designers of automotive electronics is the best solution. ”
In the powertrain systems, Cao Yu think the biggest challenge is how to coordinate the motor system and the traditional operating system power, giving the user a better driving experience. Improving the efficiency of the whole system mainly the following aspects: apple a1189 battery  improving the efficiency of the engine, the braking rate of the input energy, thereby reducing engine efficiency at low speed range of operation and so on.
In motor control, Kang Xiaodui Freescale, said the electronic engine management Freescale essentially a world leader. We offer advanced embedded controllers, sensor technology, components, power management and power brakes the drive, so that the new vehicle cheaper, and protect the environment. We always control technology introduced in motor control and electric vehicle management, and based on processors PowerArchitecture Freescale MPC55/56xx series offers many of the most advanced engine control, vehicle management, electric drive battery management solutions. ”
Battery management is facing the biggest challenge
In the (full) hybrid vehicles, the battery is more expensive but also more delicate parts. Although the lithium battery with advantages of high power density, but in the development of batteries for hybrid cars, there is still much to do. In this case, the coming years, nickel-metal hydride (NiMH), will always be more widely used.
Hans-PeterHoenes stressed that to achieve the fast charge without damage (damage) batteries, designers need a very specific charge (charge) control technology. Although the algorithm micro-controller integrated intelligent programming is essentially a software solution, but Fairchild continued to focus on the hardware. To avoid interfering with power lines during charging, a good solution for power factor correction is necessary, to some extent, even demanding the legal standard. The control IC Fairchild has a broad product portfolio, combined with built-in with a soft-recovery rectifiers (the performance of the rectifier diode) and low voltage drop across the IGBT saturation can provide a complete solution.
In managing the battery, Cao Yu Li-ion battery that Infineon has a dynamic balance of patent applications, may reduce the differences between each other, the effective improvement of battery efficiency and longevity. This patented feature is the battery charged and discharged, or any downtime to implement the balance of power, very suitable for power applications in automotive environments as varied and mode switching rapidly needs.
“Given current technology, battery technology is hybrid vehicles and electric cars key. Even a relatively high success in the market for hybrid cars, batteries are the cost of the vehicle 1 / 3 or more. But as the weight, reliability, longevity and many other problems to solve. lithium iron phosphate battery technology should be a better solution. However, regarding the above issues must still be improved. Fuel cells are another technology, its technical maturity, fuels (mostly liquid hydrogen) storage and control issues, we can say can not immediately become a mature product, mass-produced. While pure electric cars, hybrid words, the cost battery, weight, reliability, life, including the issue of pricing will be the government, car manufacturers are facing a major problem. “Xiao Kang Dun said:” So,  dell gk479 battery the current hybrid vehicles in Europe and the United States and Japan, and has become industrialized and domestic in its infancy, there is no formation of industrialization. As the world’s leading manufacturer of automotive semiconductors, Freescale is committed to consumer electronics China Motor contribute to development. Our key customer support (such as BYD, etc.), including technical exchanges, product pricing, etc.. “
