The invention discloses a battery pack monitoring method and system, an automobile and computer equipment. The method comprises the steps: obtaining the voltage of at least one temperature sensor arranged in a battery pack in real time when a battery management module connected with the battery pack is monitored to be in a dormant state; when it is monitored that the voltage of any temperature sensor exceeds a preset awakening voltage threshold value, the battery management module in a dormant state is awakened; and acquiring the real-time temperature of the temperature sensor of which the voltage exceeds a preset awakening voltage threshold value through the awakened battery management module, and prompting thermal runaway alarm information of the battery pack when the real-time temperature exceeds a preset alarm temperature value or the temperature rise rate of the real-time temperature exceeds a preset alarm temperature rise rate. According to the invention, 24-hour all-weather monitoring of the battery pack can be realized, even if an automobile using the battery pack is in a flameout parking state, the thermal runaway of the battery pack can still be monitored in time, the monitoring cost is reduced, and the battery safety is guaranteed.
本发明公开了一种电池包监控方法、系统、汽车及计算机设备,所述方法包括:在监测到与电池包连接的电池管理模块处于休眠状态时,实时获取设置在电池包内的至少一个温度传感器的电压;在监测到任意一个温度传感器的电压超过预设唤醒电压阈值时,唤醒处于休眠状态的电池管理模块;通过被唤醒的电池管理模块获取电压超过预设唤醒电压阈值的温度传感器的实时温度,并在实时温度超过预设报警温度值或实时温度的温升速率超过预设报警温升速率时,提示电池包的热失控警报信息。本发明可以实现24小时全天候监控电池包,即使在使用该电池包的汽车处于熄火停车状态时,依然可以及时监控到电池包的热失控,降低了监控成本,保障了电池安全。
