A fully integrated control system for pure electric vehicles

Abstract

The invention discloses a fully integrated control system for a pure electric vehicle. the fully integrated control system includes a motor, The water-cooled heat sink plate is fixedly connected withthe water-cooled heat sink plate through three connectors, the first water outlet at the bottom of the water-cooled heat sink plate is connected with the second water inlet of the motor, and the water-cooled heat sink plate is provided with a battery management system module, an MCU motor controller, a high-voltage distribution system module, a DC-DC control system module and a charger control system module, wherein the shell is wrapped on both sides of the water-cooled radiating plate, and the modules are all inside the shell; The fully integrated control system has the advantages of good heat dissipation effect, firm connection, high space utilization rate, short wiring harness, low complexity, low cost and less electromagnetic interference, and each interface provided on the shell realizes the connection of the fully integrated control system with the outside through high-voltage connectors and low-voltage connectors respectively.

Description

technical field [0001] The invention relates to the technical field of control systems, in particular to a fully integrated control system for pure electric vehicles. Background technique [0002] With the enhancement of people's awareness of environmental protection, people are more and more aware of the harm of traditional fuel vehicles to the human ecological environment. my country's car sales rank first in the world. In order to protect the environment, my country has chosen pure electric vehicles, plug-in hybrid vehicles The long-term development route supplemented by automobiles and fuel cell vehicles. With the gradual maturity of automobile motor technology and battery technology, the application of pure electric vehicles is becoming more and more common. Pure electric vehicles represent the development direction of future automobiles. The control system is the control center for normal driving of vehicles and the core part of electric vehicles. [0003] At present, ...

Problems solved by technology

[0003] At present, the hardware of the pure electric vehicle control system, such as the pure electric vehicle power battery management system, drive control system, charging control system, DC-DC control system, vehicle heating and cooling control system and high-voltage power distribution system, are based on independent system components. Existence, the vehicle factory needs to purchase each system component separately. During the assembly process of these independent system components on the vehicle, it is necessary to comprehensively consider the installation position and make the corresponding installation bracket, which results in a low space utilization rate; these independent system components System components need to be equipped with corresponding housings to protect their internal electronic components, which will inevitably increase the total mass of system components, and require multiple developments of housings, and the cost will increase accordingly; different independent system components have different structures , which will lead to complex assembly of the whole vehicle and poor workmanship; each independent system component needs to be connected with the corresponding low-voltage control wiring harness and high-voltage wiring harness. The electrical function interfaces of these independent system components are not uniform, and the shielding effect is poor, and there are many sources of interference; these independent system components need to be cooled during use, and each independent system component needs to be installed with water cooling Pipelines, firstly, the cost is increased, and secondly, these water-cooling pipelines take up a lot of space, which reduces the space utilization rate. The aforementioned independent system components cause damage to
