Control device for pure electric vehicle

Abstract

The invention provides a control device for a pure electric vehicle. The control device comprises an input unit, an output unit and a main control unit connected to the input unit and the output unit.The input unit includes a power supply module, an analog signal conditioning module, a switching signal conditioning module, a pulse signal conditioning module, and a development CAN transceiver. Theoutput unit includes at least one low-side drive module and one K line module. With the control device provided by the invention, the normal driving and limp home and the like of a pure electric vehicle can be controlled and power consumption of the vehicle can be managed; and the overall vehicle cooling, vehicle electric accessory controlling, high-voltage safety management, fault diagnosis andfailure mode processing are carried out by different modules and thus the management of the pure electric vehicle system is controlled precisely, so that the whole vehicle performance can meet the needs of clients.

Description

Technical field [0001] The invention relates to a vehicle management system control device, particularly a vehicle management system control device of a pure electric vehicle. Background technique [0002] Due to energy shortages, the continuous rise of international fuel prices, and governments of various countries have gradually paid attention to the issue of global warming, in recent years, people have increasingly emphasized low-carbon life, reducing emissions and protecting the environment have become issues that modern people attach great importance to. Internal combustion engine powered vehicles run counter to the concept of low carbon due to their high emissions, so pure electric vehicles that can replace internal combustion engine powered vehicles have attracted much attention. Pure electric vehicles convert electric energy provided by batteries into kinetic energy, which has a very good development prospect against the background of oil shortage and climate warming. [0...

AI Technical Summary

Problems solved by technology

[0003] In order to realize the control of pure electric vehicles, a system is needed to manage the driving of pure electric vehicles, limp home, vehicle power consumption, heat dissipation, energy recovery, power control, air conditioning and other normal work of vehicle electrical accessories, but At present, there is still a lack of devices for controlling the vehicle management system of pure electric vehicles
