Abstract

The invention discloses an improved motor controller assembly of an electric automobile, and relates to the technical field of the electric automobile. The improved motor controller assembly comprises a motor controller, a contactor and a fuse, wherein the contactor is connected with the motor controller through a copper sheet; the motor controller, the contactor and the fuse are arranged on a base; an electric potential detector is further arranged on the base and connected with the motor controller; the fuse is connected with a temperature control device and a compensating current device through a VM copper connecting sheet; the electric potential detector can be used for monitoring whether a potentiometer is open-circuit and preventing the potentiometer from getting out of control, by means of temperature protection and compensating current, subnormal temperature and over-temperature protection as well as steady current limit in the whole operating range can be provided, and damage of ultralow voltage to the motor is avoided.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to an improved motor controller assembly of the electric vehicle. Background technique [0002] The motor controller of electric vehicles is the control intermediate component of electric vehicles, which is responsible for the important role of drive system control. The motor controller is mainly composed of motor controllers, contactors and fuses. For example, Chinese Patent No. 200820091481.1 discloses a series-excited motor controller assembly, including a cooling plate and a series-excited motor controller installed on the cooling plate. , improve the heat dissipation effect of the motor controller assembly, and reduce the occurrence of failure rates, but this motor controller assembly cannot provide undervoltage protection, and the current electric vehicle technology is prone to failures caused by excessively long running time and high temperature Occurs, so there ar...
