Problems solved by technology

[0004] Due to the increase in the number of vehicle motors, the form of matching motor inverters also needs to be changed accordingly. If each motor is matched with an inverter, the number of inverters will increase, the system cost will increase, and multiple inverters will The inverter requires more installation space on the vehicle, resulting in difficulty in vehicle layout, waste of hardware resources, inconvenient wiring harness layout, and even reduced reliability; if a single inverter is used to control four motors, this mode is only applicable to four motors. Drive, two-wheel drive is difficult to adopt, and the versatility is poor

Abstract

The invention discloses a dual-motor inverter comprising a main box, a first power module, a second power module, an AC plug, a first metal bracket, a second metal bracket, a first driving board, a second driving board, a DC busbar assembly, a DC bus capacitor and a control board. The dual-motor inverter of the invention is mainly used for controlling a wheel motor or a hub motor, a cooling structure adopts parallel cooling, and the balanced cooling and heat dissipation ability of the two power modules can be ensured. A conductive terminal of the AC plug passes through a current sensor to be directly connected to the power module, an AC transition copper bar is omitted, the assembly space and the required cost of the inverter are greatly reduced, thus the dual-motor inverter has the characteristics of high integration, a compact structure, good heat dissipation effect and balanced cooling capability, high electromagnetic compatibility and convenient and fast operation, and especially the requirements of controller layout and high reliability of a new energy vehicle driven by the hub motors or the wheel motor are satisfied.

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to a dual-motor inverter for new energy vehicles. Background technique [0002] With the continuous improvement of people's awareness of environmental protection, energy saving and emission reduction, new energy vehicles have become a hot spot that major car companies and related institutions in the world are competing to develop. As one of the key components of new energy vehicles, the vehicle inverter is a key component to realize the DC power supply of the battery, the AC power conversion of the motor, and the driving operation of the motor. [0003] The existing new energy vehicles on the market mainly use a single motor to provide power. The size and power of the motor are relatively large, and a complex mechanical transmission mechanism is required to transmit the power of the motor to the wheels, which makes the overall layout of the vehicle difficult. It also li...
