Rental-electric car SHARP VL-E400U 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 (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 SHARP VL-E36C batteries and SHARP VL-E36C Battery Charger, 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 VL-E36U Battery, Battery Charger for SHARP VL-E36U, 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 VL-E37S Battery 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%.
