The invention relates to the technical field of batteries, and provides a battery thermal management system and method, a computer readable storage medium and electronic equipment. The battery thermal management system comprises a battery management unit and a characteristic parameter detection unit, the characteristic parameter detection unit is connected with the battery management unit, and the characteristic parameter detection unit is used for detecting sound in a battery box and information of gas, smoke and temperature in the early stage of thermal runaway. The characteristic parameter detection unit is used for forming a detection result signal according to the detected information; and the battery management unit is used for detecting battery information in the battery box, and the battery management unit is used for combining a received detection result signal with the battery information so as to determine a thermal runaway grade according to a sequence of characterizing information change in a thermal runaway occurrence process of the characteristic parameters, and carrying out graded early warning. The battery thermal management system can effectively predict the thermal runaway of the battery, and can increase the advance time of early warning earlier than the thermal runaway.

    本发明涉及电池技术领域,提出了一种电池热管理系统及方法、计算机可读存储介质、电子设备。该电池热管理系统包括:电池管理单元和特征参数探测单元,特征参数探测单元与电池管理单元连接,其中:特征参数探测单元用于检测电池箱内的声音、热失控前期的气体、烟雾及温度的信息,且特征参数探测单元用于根据检测得到的信息形成检测结果信号;电池管理单元用于检测电池箱内的电池信息,且电池管理单元用于将接收到的检测结果信号与电池信息结合,以根据特征参数在热失控发生过程中表征信息变化的先后顺序确定热失控等级,并进行分级预警。该电池热管理系统可以有效预测到电池热失控,且可以增加预警先于热失控的提前时间。
