Abstract

The invention discloses a battery pack thermal runaway control method, a controller, equipment and an automobile, and the method comprises the steps: obtaining a real-time pressure value of a batterypack through a pressure sensor, and judging the state of the real-time pressure value; when it is detected that the real-time pressure value is larger than or equal to a preset threshold value, awakening a battery management system; controlling the battery management system to collect battery real-time data of the battery pack, and judging the state of the battery pack according to the battery real-time data; and when it is detected that the battery pack is in a thermal runaway state, controlling the battery management system to give an alarm prompt, and sending prompt information to specifiedterminal equipment. The invention relates to the technical field of battery pack control. The state of the battery pack is monitored in real time when the battery management system enters the dormantstate, so that the battery pack can be found in time to be in the thermal runaway state to generate an alarm.

Description

technical field [0001] The invention relates to the technical field of battery pack control, in particular to a battery pack thermal runaway control method, controller, equipment and a vehicle. Background technique [0002] As a big automobile country, my country has a huge automobile market, which brings economic benefits, but also brings huge energy consumption and environmental pollution. With the increasingly fierce competition in the automotive field, various companies and universities have begun to engage in research on new energy battery vehicles, and the safety of battery packs is also a key concern. [0003] During the driving process of the vehicle, BMS (Battery Management System, battery management system) can collect current, voltage, temperature, pressure, aerosol, etc. in real time. If the threshold is exceeded, it will be processed. When the vehicle is unmanned and parked, the BMS cannot collect it in real time. . Therefore, once a thermal runaway situation ...
