The invention provides a pure electric vehicle early warning system, which comprises a power battery system, a main controller and an alarm system, and is characterized in that the power battery system comprises a power battery and a battery management system; the battery management system is used for collecting the real-time voltage of each single battery in the power battery and sending the real-time voltage information of each single battery to the main controller; the main controller is used for receiving the real-time voltage information of each single battery and monitoring the real-time voltage change value of each single battery in a preset time so as to judge whether the frequency of the real-time voltage change value of each single battery exceeding a preset threshold exceeds a preset safety frequency or not, and if the frequency of the real-time voltage change value exceeding the preset threshold exceeds the preset safety frequency, and if so, a corresponding instruction is sent to the alarm system. According to the invention, the safety and stability of the power battery system can be monitored in real time, and the safety of a blade electric vehicle user and surrounding people can be protected to the greatest extent.

    本发明提供了一种纯电动汽车预警系统,包括动力电池系统、主控制器和报警系统,所述动力电池系统包括动力电池和电池管理系统;所述电池管理系统,用于采集所述动力电池内各电池单体的实时电压,并将各电池单体的实时电压信息发送给所述主控制器;所述主控制器,用于接收各电池单体的实时电压信息,并监测各电池单体在预设时间内的实时电压变化值,以判断各电池单体的实时电压变化值超过预设阈值的次数是否超过预设安全次数,如超过预设阈值的次数超过预设安全次数,则发送相应指令给所述报警系统。本发明可实时监控动力电池系统的安全性和稳定性,且可最大可能地保护纯电动汽车用户和周围人员的安全。
