Claims

[Scope of utility model registration request]

In a storage battery electric vehicle that runs using the driving force of a DC series motor, a power generation circuit that can be switched by a manual brake switch BS is provided in the running electric circuit, and the motor M is turned into a generator by switching the brake switch BS. The current flowing from the power generating circuit during driving is converted to flow as a brake current to the electric circuit for driving to enable braking, and the rotational speed of the motor M detected by the rotational speed detector is input to the controller C. 1. A power generation braking device for a storage battery electric vehicle, characterized in that a circuit for selecting a resistance value of a brake force adjustment resistor Br is configured to be automatically switchable so that a set speed is achieved by C.
