Electric vehicle electrical components assembly

Abstract

The electric vehicle electrical component assembly provided by the present invention includes a housing, a cover body, electrical components, an insurance seat and a laminated busbar assembly. The housing and the cover form an inner cavity; the electrical components and the insurance seat are located in the inner cavity. The laminated busbar assembly includes a metal row group and an insulating substrate, and the electrical components include a motor control module, a charging module and a battery connection module; the metal row group is detachably connected between the charging module and the battery connection module; the metal row group is detachably connected Connected between the motor control module and the battery connection module. System integration design of key electrical components of electric vehicles, some electronic components are shared between important electrical components, the product is easy to install, simplifies circuit design, reduces the difficulty of vehicle electrical layout, reduces the vehicle space occupied by the electrical system, and improves the electromagnetic compatibility of the system ,reliability. The heat dissipation efficiency of the integrated whole can be higher than that of the original discrete components, thereby improving the power density of the whole integration and reducing the cost.

Description

technical field [0001] The invention relates to the technical field of vehicle accessories, in particular to an electrical component assembly suitable for electric vehicles. Background technique [0002] Electric vehicles have the characteristics of environmental protection and low pollution because they do not burn gasoline to generate power, and are widely used in places with high environmental requirements such as tourist attractions. Existing electric vehicles all need a charger and a motor controller. The charger is used to charge the battery of the electric vehicle, and the motor controller is used to control the motor of the electric vehicle. Both the charger and the motor controller include a power board and a motor controller. Power units, etc., controllable switching devices, that is, power tubes, such as thyristors or IGBTs, need to be set between the power board and the power unit to control the motor. [0003] The key electrical components of electric vehicles ...

AI Technical Summary

Problems solved by technology

[0003] The key electrical components of electric vehicles include motor controllers, chargers, DC converters, and power distribution units. The four major components used in electric vehicles on the market today are all independent components. Each component needs to be installed independently, and each component must be installed independently. The battery needs to be connected, the wiring is complicated, and the installation is very cumbersome. At the same time, it also increases the difficulty of vehicle layout, resulting in high cost, which is not conducive to popularization and use.
