Description

Wake-up device, wake-up control method, storage medium, energy storage system and electric equipment Technical Field The application relates to the technical field of battery thermal management, in particular to wake-up equipment, a wake-up control method, a storage medium, an energy storage system and electric equipment. Background Thermal runaway is a serious safety failure of battery systems. When the heat of a certain battery is out of control, a large amount of high-temperature gas and heat can be instantaneously generated, so that the internal pressure and temperature of the battery pack are rapidly increased. If the high temperature and flame cannot be effectively isolated, a chain thermal runaway reaction, namely heat spreading, of the adjacent cells can be triggered, and finally the whole cell pack can be ignited and exploded. A Battery Management System (BMS) MANAGEMENT SYSTEM, which is abbreviated as BMS throughout, can collect signals of voltage, temperature, pressure, etc. in real time when a vehicle is running (operating state) to determine whether thermal runaway occurs. However, when the vehicle is in a stopped state, the BMS may enter a sleep mode in order to save power. In the parking stall state, most of the sensing functions of the BMS are turned off. If the battery is thermally out of control at this time, the BMS cannot sense and wake up by itself, and thus cannot perform a corresponding malfunction operation. In the related art, the wake-up of the BMS depends on an electronic wake-up signal sent by a sensor, and the reliability is low.
