To industry sources, according to the current models on the market Genuine BL-5C battery price 80 yuan each count, its only product replacement cost of more than 30 million, In addition, there will be a lot of labor costs. Throughout the recall costs will be shared Nokia and Panasonic thinkpad R50P battery , thinkpad R51 battery.
According to foreign media reports, the U.S. Consumer Product Safety Commission (CPSC) spokesman confirmed this week four, the agency has begun Nokia battery recall incident.
CPSC spokesman said: “This is a matter of concern, we are investigating this. So far, no recall of the batteries in the U.S. market.”
It is reported, CPSC is mainly worried about the battery after being hit by heavy external short-circuit. The spokesman said: “If the internal short circuit may lead to fire, although this situation does not often happen.”
Nokia announced this week two, because of overheating risks that it would recall 46 million mobile phone batteries affected as many mobile phones as many as 52 models. According to analysts expect the cost of the recall is expected to reach 500 million euros.
O2 Graphite Smartphone SP strongest down 2199
The introduction of Windows Mobile system, intelligent machine is divided into the Pocket PC handwriting handwritten Smartphone platform and non-camps, in which the non-use Smartphone handwriting intelligent machines as closer to the ordinary operation of mobile phones has been a lot of thinkpad R52 battery , thinkpad R60 battery smart players welcome , particularly in the five departments headed by Dopod, Smartphone camp is the star of series. However, Dopod 5 Series also has its own weaknesses, the lower the hardware configuration for many of the players whom the pursuit of high-performance regrets. From the UK operator O2 launched in 2006, a high frequency processor Smartphone mobile phone XDA Graphite (graphite), small size and the performance is more powerful. Electronic eye at the point I learned that this quote O2 graphite prior to 2380 yuan from 2199 yuan down, cost-effective even better, like the Smartphone platform, intelligent machines may look a friend.
O2 XDA Graphite shape with the classic candybar design, silver and gray body color reflects a deep breath of the business, 109.5 × 46.9 × 18mm body measurements and 105 grams of body weight for this powerful, intelligent Business Machines is also just right, very suitable for carrying. XDA Graphite-based 3G networks, using a 2.2-inch 60005 thousand color QVGA-resolution TFT screen, 16-bit support for the natural tones MP3, AAC and other music format files playback at the same time equipped with a 2 million pixel primary camera and a a 30-megapixel camera Sok, vice head, the machine pre-loaded with Windows Media Player 10.3 Mobile Office players and office software, high-frequency processor makes XDA Graphite has a very good performance of the business and entertainment.
On the hardware configuration, XDA Graphite using Windows Mobile5.0 for Smartphone platform, it is worth mentioning is the XDA Graphite using 416MHz Intel XScale PXA270 series processors, which can be said that the current performance of SP cell phones the most powerful CPU of the , with 128MB ROM and 64MB SDRAM memory, even if running a large program would also ensure smooth speed, which makes the Smartphone camp XDA Graphite become the most powerful models.
In the extended performance on the XDA Graphite is also very comprehensive thinkpad R60e battery , thinkpad R61 battery , thinkpad R61e battery, it is the greatest support 2GB capacity micro SD card memory expansion, but does not support hot-swap technology, will bring some inconvenience to the use of peacetime. In addition, it supports Bluetooth 2.0 wireless transmission of data, as well as A2P stereo Bluetooth music support WLAN 802.11b / g wireless LAN. O2 Graphite is equipped with a large-capacity 1100mAH lithium battery, the longest standby time of 275 hours.
Toyota, Denso LS600h new PCU and 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, 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 thinkpad R61i battery , thinkpad T40 battery 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 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 thinkpad T40P battery , thinkpad T41 battery reduced by about 30%.
