新能源电动车的低压电源管理策略分析

Analysis of Low Voltage Power Management Strategy of EV Car

新能源车低压电源管理系统根据整车的工作状态需区分不同的管理策略,从而在保证整车的正常使用状态下尽量节省电能、减少能量浪费。介绍了静态电流监控与管理策略、负载分级管理控制策略DC/DC管理控制策略和跛行控制策略等低压电源管理策略的工作原理及流程,分析了新能源电动车的低压电源管理策略,并提出了优化措施。

The low-voltage power management system of new energy vehicle needs to distinguish different management strategies according to the working state of the vehicle,so as to save electric energy and reduce energy waste as much as possible under the condition of ensuring the normal use of the vehicle.The working principle and process of low-voltage power management strategies were introduced such as quiescent current monitoring and management strategy,load grading management strategy,DC/DC management strategy,and limp control strategy,the low-voltage power management strategies of new energy electric vehicles were analyzed,and optimization measures were put forward.
