Abstract

The invention discloses an integrated power system of an electric automobile. The system comprises an upper casing, an intermediate casing and a lower casing which are successively connected from top to bottom, wherein the upper casing is internally provided with a high-voltage conjunction box and a VCU (vehicle control unit), a motor controller is arranged in the intermediate casing, a vehicle-mounted charger and a DC-DC module are arranged in the lower casing, the end surface of the bottom of the intermediate casing is provided with a cooling water channel, and a water inlet and a water outlet of the cooling water channel are led out of the intermediate casing. According to the invention, a housing is divided into three cavities, five major parts are reasonably distributed to the three cavities, while normal connection and operation of each part are guaranteed, there are abundant space for vehicle arrangement, and the vehicle arrangement is more beautiful; and the cooling water channel is arranged between the intermediate casing and the lower casing, the motor controller, the DC-DC module and the vehicle-mourned charger share the cooling water channel, and the three are cooled during work so that normal operation of the three is guaranteed.

Description

technical field [0001] The invention relates to the field of electric vehicles, in particular to an integrated power system of the electric vehicle. Background technique [0002] At present, electric vehicles with zero emission and no pollution have been paid more and more attention by various countries. Electric vehicles cancel the engine, transmission, supply system, exhaust system, etc. on the basis of traditional vehicles, and replace them with electric motors, reducers, power batteries, motor controllers, on-board chargers, high-voltage junction boxes, VCU, DC-DC modules, etc. parts. Among them, due to the different structures of the motor controller, on-board charger, high-voltage junction box and DC-DC module, if the layout is not reasonable, it will not only waste the installation space of the car, but also affect the normal operation of the power system. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide ...
