一种电池热失控的预警装置
By designing a battery thermal runaway early warning device, the battery parameters are monitored in real time and the charging and discharging mechanisms are automatically separated in the event of thermal runaway. This solves the problem that existing technologies cannot actively prevent battery spontaneous combustion and achieves safe control of battery thermal runaway.
