Research of the electric vehicle safety standard

One of EV power system´s important characteristics is high voltage and large current. Creepage distance of EV on-board energy storage device should be less than safety margin, for avoiding such harm that from explosion, fire or toxic substances, the protection of power battery overcorrect should have corresponding security standard. The electric motor drive of EV may appear faults when facing the special danger situation. So we should take some measures to ensure that it could work normally and avoid fault. It should be required that there are corresponding safety measures to protecting personnel electrocuting when EV without external power supplies. It should be required the measures for in case of short circuit, for protecting the harm to passengers and the third party from on-board energy storage device when vehicles colliding, too.
