Electric vehicle high-voltage distribution control cabinet packaged with DC module and charging module

Abstract

The invention discloses an electric vehicle high-voltage distribution control cabinet packaged with a DC module and a charging module. The electric vehicle high-voltage distribution control cabinet comprises a high-voltage distribution module, the charging module, the DC module, a water-cooling heat dissipation mechanism, an upper frame, a lower frame, an upper cover, a lower cover and a sealing ring. The upper frame and the lower frame are each in a square shell shape without a top face. The high-voltage distribution module is installed in the upper frame. The charging module and the DC module are installed in the lower frame side by side. The upper frame is installed on the top of the lower frame. The bottom face of the lower frame is provided with a wire through hole. The high-voltage power distribution module is electrically connected with the charging module and the DC module. The bottom face of the lower frame sinks to form a water-cooling heat dissipation mechanism installation groove. The water-cooling heat dissipation mechanism is installed in the water-cooling heat dissipation mechanism groove. The sealing ring is located at the position, making contact with the lower frame, of the upper frame. The top of the upper frame is covered with the upper cover. The water-cooling heat dissipation mechanism installation groove is covered with the lower cover. According to the high-voltage distribution control cabinet, the DC module, the charging module and the high-voltage distribution module are packaged into a whole, less space is occupied, dismounting and mounting are easy, and the problem that wire harnesses are messy is solved.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to an electric vehicle high-voltage power distribution control box packaged with a DC module and a charging module. Background technique [0002] Electric vehicle high-voltage power distribution cabinet (box / box) is a high-voltage and high-current distribution unit (PDU) for all pure electric vehicles and plug-in hybrid vehicles. Its main function is to control the on-off of the internal high-voltage relay through the external low-voltage control circuit, connect the high-voltage DC power supply of the power battery according to the internal design circuit of the high-voltage power distribution box, and connect the motor controller of the driving and steering motor, the car charger, air conditioner, DC A series of high-voltage components such as modules (DC voltage converters) are connected together. [0003] However, the existing high-voltage power distribution box has a...
