Method and device for battery thermal runaway protection and machine readable storage medium

The embodiment of the invention provides a battery thermal runaway protection method, a battery management controller, a battery and a machine readable storage medium. The method comprises the steps that a battery state signal is received from a battery, and the battery state signal is used for indicating the state of the battery; determining whether the battery is in a thermal runaway early warning state based on the battery state signal; if it is determined that the battery is in the thermal runaway early warning state, a trigger signal is sent to the battery, and the trigger signal is used for triggering the battery to execute protective measures for thermal runaway. 本公开内容的实施例提供了用于电池热失控保护的方法、电池管理控制器、电池和机器可读存储介质。该方法包括：从电池接收电池状态信号，其中，电池状态信号用于指示电池的状态；基于电池状态信号，确定电池是否处于热失控预警状态；如果确定电池处于热失控预警状态，则向电池发送触发信号，其中，触发信号用于触发电池执行针对热失控的保护措施。
