The reasons for the battery flaw

The reasons for the battery flaw

Sony Corporation (Sony Corp.) Last year, regarding the voluntary recall of laptop Dell Inspiron 1420 Battery has created a hubbub, but a year later, after Matsushita Electric Industrial Co., Ltd. (Matsushita Electric Industrial Co. Ltd.) Reverted to Sony’s mistakes, this highlights the battery industry, some of the problems still exist.

Nokia Corporation (Nokia Corp.) Tuesday said that the 4,600 million Nokia mobile phones Panasonic products used in lithium-ion batteries, some of the overheating problems were reported there. Nokia said it would under the voluntary recall program to replace these batteries. The minor number of the company to replace the battery is still unknown, but the number of potential replacement of the Sony recall last year’s event four times, thus becoming the battery industry’s largest product recall incident one.

Since August last year, Dell Inc. (Dell Inc.) Shocking to announce that Sony’s massive recall of notebook computer lithium-ion battery, the battery industry has been similar incidents in other troubled companies. Almost all of the major computer makers have announced the recall of Sony notebook computer batteries, while Sanyo Electric Co., Ltd. (Sanyo Electric Co. Ltd.) Also recalled notebook computer and cell phone Dell Inspiron 1501 Battery.

Frequent exposure of the battery recall problems and recurring events, on the one hand be attributed to manufacturers more and more attention on consumers begin to make a more resolute response, but also exposed the difficulty of the battery manufacture its own how high.

Rechargeable lithium-ion battery with cheap, light weight, and more than nickel-cadmium batteries, and other types of battery is more environmentally friendly, etc., thus the laptop computer and cell phone industry to be successful in the past 15 years, a major contributor.

However, large capacity lithium-ion battery production difficulties are also great, and easier to overheating, once the circuit than the alkaline batteries can cause more serious consequences. Sony’s battery caught fire last year, once the accident occurred. The Nokia Panasonic Dell Inspiron 1520 Battery recall is in the charging process will overheat.

Even worse is that now more and more complex computers and mobile phones, and the pace of development than the battery technology advances, which means that the battery capacity will keep rising.

Lithium-ion battery technology, taking into account the shortcomings, Toyota Motor Corporation (Toyota Motor Corp.) Has been delayed its application in hybrid cars on the plan. But industry experts said that despite the lithium-ion battery has its limitations, but in the foreseeable future is still the most practical battery technology.

In order to maintain its market share, Sony this week announced that it would spend ¥ 11,500,000,000 (equivalent to 9,760 million U.S. dollars) building a cell phone battery factory in Singapore, and will employ more advanced technology to produce lithium-ion polymer batteries. The plant to be put into production in August next year, an initial monthly capacity of one million batteries by 2010 will rise to 8 million.

Japan’s Toshiba Corp. (Toshiba Corp.) Other vendors are developing fuel cells, alternative energy technologies. This Dell Inspiron 1521 Battery will get rid of the shackles of chemical energy, but still long way from commercialization.

As the world’s one of the four lithium-ion battery manufacturers, Matsushita said the battery recall problem in the manufacturing process due to the battery positive and negative electrodes used for barrier in order to prevent short circuits were damaged parts. Of these batteries overheating caused by Nokia mobile phones are only 100 cases of complaints, and no person has serious injuries. But Nokia said that in order just in case, will replace Matsushita from December 2005 to November 2006 in Osaka, the main factories for producing all of the same types of battery.

Panasonic is expected to recall most of the cost will be borne with dell latitude d520 battery, it was estimated that this cost at 200 billion yen. Matsushita Electric’s shares in the Tokyo Stock Exchange (Tokyo Stock Exchange) closed at 2,015 yen per share, down nearly 5%.

Chevy Volt information

Chevy Volt information

Rental-electric car canon nb-4l batteries is a very bold idea, where the fuel age is incomprehensible.

Chevy Volt General Motors has just launched this year, the electric-powered cars start we all think this is a concept car, but GM does not seem so to read. They are prepared to extend it civil.

The use of electric drive systems, and engines – as a back-up generators, Volt can reach 640 miles of driving range. It allows the driver to work do not start the internal combustion engine, while the ability to conduct long-distance travel. Worth noting that there is no “induction charger” (GMEV1 the main part), or 220V charging stations that can do all those things. GM engineers said the Volt’s lithium-ion batteries 110V, 15A household power supply can charge 6-7 hours.

But unlike oil, the fuel tank, and there is not much cost, but the cost of lithium casio np-20 batteries, but considerable. The current cost approximately: $ 300/kW-hr, or even as high as $ 500/kW-hr, this is the biggest obstacle to the promotion Chevy Volt.

GM decided to lease the battery pack to the consumer or to eliminate the spread of the threshold electric-powered cars.

Toyota, Denso LS600h new PCU and digital camera battery cooling system open

Denso to use newly developed hybrid power control unit (PCU) and battery cooling system. PCU consists of two parts, including the main hybrid battery voltage 288V maximum voltage 650V step-up to the system, the converter, as well as direct current into alternating current output, and drive the vehicle power source – motor inverter. In order to improve the output power of PCU needs to constitute a separate PCU to increase the number of power semi-reactive body power, but nonetheless there is how to check the temperature go up issues. To this end, the company through the use of self-developed PCU cooling structure of the power increase will be PCU output power per unit volume increased by about 60%. In this way, in the same power, the comparison with the original casio np-100, PCU volume can be reduced about 30%, weight can be reduced about 20%. Application of the PCU’s products in May 2007 has been listed by the Toyota hybrid “Lexus LS600h/LS600hl” on the adoption.

In the original PCU, multiple power semiconductors, flat configuration through the cooling plate on the cooler can only be cooled by cooler side. The structure of the development will be caught in the power semiconductor 1 on the cooling plate, and then insert the upper and lower tubular product cooler. In this way, from the power semiconductor can be cooled on both sides, but also realized miniaturization.

In addition, the cooling structure of the new laminated on both sides of the direct connection of power semiconductors, and dovetail with the cooling plate. In order to ensure that the bonding reliability of power semiconductors thinning by inhibiting the stress exerted on the junction point. In addition, PCU’s output power by minolta np-600 changing the power semiconductor and the cooling pipe of the number of laminated pieces can reach the desired value.

In addition, the battery systems, cooling fan can be used not only to the car of the air, but also after use seats refrigeration units are air-conditioned with cooling. In this way, in order to approximately the original 1 / 2 the amount of wind can be given the same cooling performance, air supply noise can be reduced by about 30%.
