Beschreibung
Zusammenfassung:	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
