Abstract
An electric system of an electric vehicle including a main battery as a power supply, and a semiconductor power converter for driving a wheel driving motor. Impact destroying switches are inserted into connecting lines which connect a main battery to the semiconductor power converter, and into a connecting line connecting main battery block. Each impact destroying switch breaks its conduction by blasting an explosive in the switch in response to the impact due to a collision of the vehicle body. In case of an emergency such as a collision, since the main battery is instantaneously disconnected from the connecting lines by the switches, the connecting lines become free from the voltage. This makes it possible to prevent fire, and to cut off the vehicle body to save passengers.
