The invention relates to the technical field of electric vehicle battery management, in particular to an electric vehicle battery internal temperature safety early warning method and a monitoring system. The safety early warning method comprises the steps that a database of battery pack discharge characteristics is configured in a BMS of the electric vehicle; recording discharge data information of the battery pack in each travel of the electric vehicle in a database; in the running process of the electric vehicle, real-time discharge data information of the battery pack is collected; and comparing the real-time discharge data information with discharge data information in a database, and giving an alarm when the discharge data information is abnormal. According to the invention, the battery parameters in the running process of the electric vehicle are monitored according to the performance of the discharge characteristics of the battery in each travel, and an alarm is given in time when abnormality is found, thereby achieving the purpose of safety early warning of the internal temperature of the battery and improving the safety of the electric vehicle.

    本发明涉及电动汽车电池管理技术领域,具体涉及一种电动汽车电池内部温度安全预警方法及监测系统。安全预警方法包括:在电动汽车的BMS中配置电池组放电特性的数据库;在数据库中记录电动汽车每次行程中的电池组的放电数据信息;在电动汽车运行过程中,采集电池组的实时放电数据信息;将实时放电数据信息与数据库中的放电数据信息进行比对,异常时发出警报。本发明根据历次行程中电池放电特性的表现,监测电动汽车运行过程中电池参数,发现异常及时报警,以实现对电池内部温度安全预警的目的,提高电动汽车的安全性。
