摘要
电池是新能源汽车重要的动力来源,电池管理系统(Battery Management System,BMS)主要负责电池的安全保护,防止电池出现过充、过放,使电池工作在合理的温度区间,进而延长电池寿命,提高整车性能。本文首先对BMS的核心技术进行阐述;其次对电压采集、电流采集、热管理、SOX估计等功能进行分析;最后,在当今人工大数据和人工智能发展趋势下,对BMS的发展前景进行了展望。
Battery is the main power source of the new energy vehicle.Batter y Management System(BMS)is responsible for the safety protection of the battery.To extend the life of battery and improve the performance of the vehicle,BMS can avoid the battery in over-charge,over-discharge state;and keep the battery in operational temperature range.Firstly,this paper has a short describe a bout BMS function,then has an analysis a bout the key function,like voltage sample,current sample,thermal management,SOX estimation,.etc.Finally,the future development trend of BMS is prospected at the ground of Big Data and artif icial intelligence.
