Abstract

The invention relates to a control-charge protector of electric vehicle, wherein it can control the torque, speed, charge protection and brake cut-off of electric vehicle. The bottom plated is arranged with charge relay, brake cut-off relay; the key switch is mounted on steering disc; the break switch is mounted on the brake integrity of front plate; the direction switch is mounted on the right motor frame; the accelerator is mounted on the front plate. The invention has simple structure, with which the electric vehicle can not start in charged, to improve safety.

Description

technical field [0001] The invention relates to a control and charging protection device for an electric vehicle, specifically a control system for controlling the torque and speed of an electric vehicle, charging protection, and braking and power-off, belonging to control and safety protection [0002] technology field. Background technique [0003] When an electric vehicle is running, its torque and speed, charging protection, brake power-off control system must meet the national technical requirements for electric vehicle safety, and the electric vehicle must be powered off when charging. The original controller adopts fixed chopper, control line fuse, main line fuse, backward contactor, forward contactor and main contactor on the bottom plate. This kind of structural controller cannot realize that the electric vehicle cannot be started when charging, so there is an unsafe factor. Contents of the invention [0004] The object of the present invention is to overcome th...
