摘要
电动汽车核心是电池管理系统,其具备对电池单元电压、电流、内部温湿度等参数实时采集、动态监控、数屏显示,还具备对电池的故障报警、断电保护功能。电池性能是电动汽车的制约因素,而传感器则对电池管理系统有着决定性作用。本文介绍电动汽车电池管理系统的基本功能,着重分析电池管理系统电流传感器、温湿度传感器、电压传感器、位置传感器应用与功能发挥,提出电池管理系统传感器技术未来发展的趋势。
The core of the electric vehicle is the BMS,which has real-time collection,dynamic monitoring,and digital screen display of battery cell voltage,current,internal temperature and humidity and other parameters.It also has the functions of battery failure alarm and power failure protection.Battery performance is a limiting factor for electric vehicles,and sensors play a decisive role in BMS.This article introduces the basic functions of the battery management system of electric vehicles,focusing on the analysis of the current sensor,temperature and humidity sensor,voltage sensor,position sensor application and function of the battery management system,and proposes the future development trend of the BMS sensor technology.
