摘　　要：针对能源危机的现状,对新能源汽车的核心部件锂离子电池的应用性能进行了研究。通过使用电动汽车智能监控和管理系统对电动汽车锂离子电池进行监测和管理,能够系统地对电池的电量、电压、电流、车辆运行速度、车辆方向、车辆位置、报警信息、故障情况等因素进行监测,将车辆在充电过程和运行过程中各项电池参数的数据进行采集,研究磷酸铁锂电池的性能规律,分析锂离子电池的总电压、总电流、单体最高电压、单体最低电压、模块最高温度和模块最低温度的变化情况。结果表明,锂离子电池在电动汽车的应用中性能稳定且规律,电池的一致性良好。In view of the current situation of energy crisis,the characteristics of lithium-ion battery in electric vehicle have been studied in the article. By using the electric vehicle monitoring and management system to monitor the battery at all times,the system can monitor the battery power,voltage,current,vehicle speed,vehicle direction,vehicle location,alarm information,the fault factors and other information,and it has gathered various parameters of the vehicle in the charging and running process and researched the charging and discharging performance rule of the battery. The total voltage,total current,monomer maximum / minimum voltage and module highest / lowest temperature have been studied. The results indicate that the lithium-ion battery used in electric vehicle has a good performance and consistency.
