Abstract

The invention discloses a multifunctional driver and a new energy vehicle. The driver comprises a driver shell. Multiple functional modules are arranged in the driver shell. The function modules are installed in the driver shell in a separated mode. An upper cavity and a lower cavity are formed in the driver shell, a heat dissipation plate is arranged between the upper cavity and the lower cavity,a plurality of heat dissipation flow channels are formed in the heat dissipation plate, an integrated main control module is installed on the top layer of the upper cavity, and a motor control module, an oil pump control module and an air pump control module are arranged on the integrated main control module. According to the invention, the function modules in the driver are installed in a separated manner. Control circuits of the functional modules are integrated on the integrated main control module. The heat dissipation plate integrated with the plurality of heat dissipation flow channelsis arranged in the middle of a driver, so that the anti-electromagnetic interference capability and the heat dissipation performance of the driver are improved, the reliability of the driver is improved, and meanwhile, all functional modules in the driver are arranged more flexibly and are convenient to assemble and maintain.

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to a multifunctional driver and a new energy vehicle. Background technique [0002] As the country pays more and more attention to energy and environmental protection issues, the development of new energy electric vehicles is gradually accelerating, and the main motor drivers of new energy vehicles have also been widely used. In the actual application process of drives, OEMs have higher and higher requirements on the cost, power density and reliability of drives. However, most of the drivers on the market currently adopt a separate structure, with low integration, and each functional module has a single function, requiring complicated hard-wired connections, resulting in high prices for the driver, and a large overall size, which affects the efficiency and reliability of the vehicle. Contents of the invention [0003] The purpose of the present invention is to overcom...
