Claims

[Scope of utility model registration request]

In an electric vehicle that performs regenerative braking control using a compound-wound motor or a shunt-wound motor, the main starting resistor is configured such that one end of the main starting resistor is disconnected from the main circuit during regenerative braking. An electric motor characterized in that it is composed of a group of contactors for short circuit, a regeneration failure detector that detects that the regeneration brake has expired, and a power generation brake contactor that is operated by the output of the regeneration failure detector. car control device.
