City electric car battery disconnect device conflicts

摘要

The subject innovation is one to, more particularly, to cut off the power supplied to the electrical component of the electric car by a signal detected by sensing the impact force exerted from the outside of the electric vehicle during traveling relates to a blocked battery power when electric vehicle collision device as to provide an electric vehicle collision the battery power-off device, in the power supply device that via the ignition key contact to energizing the battery power for an electric vehicle supplies the driving power to the electrical component, is installed in the front and rear of said electric vehicle outside therefore comprises a shock sensor for detecting a pressure, parts of the relay of the battery power by the signal detected by the impact sensor bypass applied from preventing a fire is generated in the power source line short-circuit of the electric vehicle in advance It has the advantage that.
