Power Failure of Common Faults in Vehicle Control System
The new energy vehicle control system is an indispensable core part of the new energy vehicle,which is re-sponsible for the vehicle's driving control,energy management,network management,fault diagnosis and processing and vehicle status monitoring and other functions to ensure that the vehicle can run stably in an efficient,economic and relia-ble state.This paper takes Geely EV450 as an example,through in-depth analysis of the lines of the control system of new energy vehicles,especially the fault diagnosis and detection of+B power supply,IG ignition switch power supply and power supply(also known as continuous power supply),to deepen students'understanding of theoretical knowledge,further improve practical ability,and cultivate safety awareness.Stimulate students'interest in independent learning.
