Embodiment 1

[0025] According to an aspect of an embodiment of the present invention, a power supply control circuit is provided, figure 1 is a schematic diagram of a power supply control circuit according to an embodiment of the present invention, such as figure 1 As shown, the power control circuit includes: a vehicle power supply module 11 , a first main control module 13 and a second main control module 15 . The power supply control circuit will be described in detail below.

[0026]The vehicle-mounted power supply module 11 is used to input the vehicle-mounted low-voltage power supply for the first main control module and the second main control module, wherein the first main control module is the control module of the drive circuit of the main motor, and the second main control module is the control module of the auxiliary motor. The control module of the drive circuit.

[0027] Optionally, the on-board power supply module here can be an all-in-one driver. On the control board of t...

Embodiment 2

[0058] According to another aspect of the embodiments of the present invention, there is also provided an electric vehicle using any one of the above power supply control circuits.

[0059] In the power supply control circuit in the embodiment of the present invention, the control power supply system of the multi-in-one driver is mainly divided into a main drive power supply system and an auxiliary drive power supply system, and the two power supply systems are similar. After the vehicle-mounted low-voltage DC power supply (24V power supply) is input to the all-in-one driver, it is distributed to the main control part of the main motor drive and the main control part of the auxiliary motor drive after being filtered by capacitors, common mode inductors, and inductors. The main control part of the main drive mainly has three parts of power supply, one for the IGBT drive circuit of the main drive, the other for the power supply of the resolver decoding part, and the third for mul...

Abstract

The invention discloses a power supply control circuit and an electric automobile. The power supply control circuit comprises a vehicle-mounted power supply module used for inputting a vehicle-mountedlow-voltage power supply to a first main control module and a second main control module, the first main control module is a control module of a driving circuit of a main motor, and the second main control module is a control module of a driving circuit of an auxiliary motor; a first main control module which is used for distributing a first low-voltage power supply to each power utilization module of a driving circuit of the main motor, and the first low-voltage power supply is a power supply input by the vehicle-mounted power supply module; and a second main control module which is used fordistributing a second low-voltage power supply to each power utilization module of the driving circuit of the auxiliary motor, wherein the second low-voltage power supply is a power supply input by the vehicle-mounted power supply module. According to the invention, the technical problem of low reliability due to the fact that most electric control units are all-in-one drivers in the prior art issolved.

Description

technical field [0001] The invention relates to the technical field of electric vehicle drive controllers, in particular to a power supply control circuit and an electric vehicle. Background technique [0002] In a pure electric commercial vehicle, the electronic control unit is mainly composed of a power motor driver (main motor driver), a vehicle controller, an auxiliary driver (including: oil pump driver, air pump driver and DC step-down converter DCDC), a high-voltage power distribution part and battery management and other parts. Among them, the driving parts such as the main motor driver and the auxiliary driver are separated from each other on the vehicle, occupying limited space on the vehicle, making it difficult to maintain and having a high overall cost. It has become a trend to integrate the main motor driver, auxiliary driver, high-voltage power distribution part, and even the vehicle controller to make multiple drivers into one driver. At present, the common ...
