Protecting device of electromobile
First Claim
1. A protecting device for use with an electromobile having a control device to control a rotating speed of a motor using a primary battery as a power source on the basis of an accelerator signal and a brake signal, said protecting device comprising:
- a current detecting means for detecting a value of a current of the primary battery and outputting a detecting signal indicative of the value; and
a stopping means for stopping supply of electricity to the motor when the current of the primary battery is abnormal based on the detecting signal output by said current detecting means.

Abstract
A protecting device of an electromobile has a control device to control the rotating speed of a motor on the basis of an accelerator signal, a brake signal, and output signals from an encoder sensor, a commutation sensor, and a phase current detector, which includes a device for detecting interruption of input of the output signals and outputting detecting signal, a device for stopping supply of electricity to the motor in response to the detecting signal of the detecting device, a device for detecting a value of a phase current of the motor and outputting a detecting signal when the phase current is abnormal, and a device for stopping supply of electricity to the motor in response to the detecting signal of the phase current detecting device.
