A power control box for an electric drive vehicle

Abstract

The invention relates to a power control box for electric cars. The power control box is characterized by comprising a control box body and a cooling substrate. The cooling substrate is arranged at the inner bottom of the control box body. A motor controller module, a pneumatic pump control module, a steering pump control module and a DC / DC (direct current to direct current) module are respectively integrated onto the cooling substrate in the control box body. A connecting protrusion is arranged on one side of the control box body. The motor controller module, the pneumatic pump control module, the steering pump control module and the DC / DC module are connected with the connecting protrusion through a plurality of copper bars. A generator control module is arranged outside the control box body and below the connecting protrusion. The power control box for electric cars has the advantages that the power control box is compact in structure, high in module integrity, space-saving, convenient to install and easy to maintain and gathers the control modules in the limited space; wires and cables for connection inside the control box body are omitted, the control modules are connected through the connecting copper bars while the control modules also are connected with the connecting protrusion through the connecting copper bars, and the problems of conductors due to clustered wires and cables, rubber aging and the like are avoided.

Description

technical field [0001] The invention relates to a power controller, in particular to a power control box for an electric drive vehicle. Background technique [0002] In traditional automobiles and electric vehicles, the electronic control modules of the various systems of the automobile are relatively independent. Its disadvantages are: 1. The layout of each module is scattered, which takes up a lot of space in the car. For the limited space of the car; 2. Each module must have an independent shell, bracket and cooling system, which increases the weight of the car; 3. Since the modules are arranged in different positions of the car, it is inconvenient to centralize management and maintenance; 4. The wiring harness is not easy The layout is complicated and confusing; 5. Each control module is cooled separately, requiring multiple sets of cooling devices. Contents of the invention [0003] The object of the present invention is to provide a power control box for an electric...
