Abstract

The invention relates to an electromobile and an electronic control device integration device thereof. The electronic control device integration device comprises a main control monitoring unit, a motor controller set, an electrical accessory controller set, a first pre-charging circuit and a second pre-charging circuit, all of which are arranged in a centralized mode. A vehicle-mounted high-voltage direct current port is connected with the motor controller set through the first pre-charging circuit and is connected with the electrical accessory controller set through the second pre-charging circuit. The main control monitoring unit is connected with the first pre-charging circuit and the second pre-charging circuit in a control mode. By means of the integration design, the structure is more compact, arrangement is neater, high-low voltage wiring harness connecting and number of connectors are reduced, and the stability of whole electromobile running is improved; by means of the independent pre-charging circuits and a main contactor, the power-assisted steering and low-voltage power supplying of the whole electrombile are normal when a motor controller of the power of the whole electrombile breaks down, and the safety of the whole electromobile running is improved.

Description

technical field [0001] The invention relates to an electric vehicle and an integrated device for electric control devices thereof. Background technique [0002] Energy and the environment are two important issues that must be addressed in social development. By saving energy and diversifying energy sources, electric vehicles can optimize the energy consumption structure and improve the environment, and have significant social and economic benefits. The electric system components of new energy electric vehicles mainly include: motor controller group (drive motor controller and generator controller), electric accessory group (electric power steering, air compressor, DC / DC), etc. At present, the motor controller, electric power steering controller, air compressor controller, and DC / DC used in electric vehicles are all designed independently, and each part is connected by a high-voltage and low-voltage wiring harness. This application method mainly has the following disadvanta...
