Abstract
Energy depletion becomes much more popular especially for petroleum decline sharply, all country on the earth try to decrease their usage of petroleum seriously. Electric vehicle (EV) technology holds much promise for reducing the demand for petroleum and reducing the emission of carbon dioxide. However, the most important issue for EV is its power supply – battery module. Therefore, we propose this architecture which is cooperate between EV network design and remote diagnostic service in order to extend the life of battery and raise the safety of EV driving. All of systems on the vehicle can communication each other and have appropriate action to raise the efficiency of battery usage through the EV network design. Otherwise, the remote diagnostic service can provide drivers the better strategy to resolve some simple problem and recharge the battery via this cooperative architecture. This architecture can increase the mass population of EV and guarantee the quality of battery to raise the utility rate.
