<p>PURPOSE:To eliminate the risk of fire by disconnecting a battery from the circuit at the time of emergency, e.g. crash, and presenting no voltage on the connecting line and to allow the cutting of car body for the purpose of rescue of passenger. CONSTITUTION:In the electric system of electric automobile for driving a wheel drive motor with a source battery through a semiconductor power converter, switches 301-304 for exploding internal explosives with the impact of crash to disconnect the circuit are inserted into the connecting lines 202 between main battery blocks 110, 120 and the connecting lines 201, 203 with an inverter 4. These switches 301-304 are operated by a firing signal delivered from a control circuit 400.</p> |
