The invention relates to a battery control method and device, a battery management system, a storage medium and a computer program product, and the method comprises the steps: firstly controlling a switch device at a power obtaining side in two switch devices which are connected in a back-to-back manner to be switched on, and enabling a switch device at a power supply side to operate in a heating mode; and then under the condition that the overcurrent operation of the target battery meets the preset turn-off condition, the two switching devices are turned off at the same time. According to the scheme, when overcurrent occurs, the switching devices are not directly switched off, one of the switching devices continues to be switched on, the other switching device is controlled to operate in a heating mode, surge energy is absorbed through heating, the surge energy is dissipated in the packaging structure of the switching devices, and the two switching devices are switched off until the preset switching-off condition is met. The soft turn-off control of the switching device is realized, so that the influence of induced electromotive force generated by parasitic inductance on the switching device is reduced, and the switching device is prevented from being broken down.
本申请涉及一种电池控制方法、装置、电池管理系统、存储介质和计算机程序产品,在目标电池发生过流的情况下,首先控制背靠背连接的两个开关器件中,得电侧的开关器件导通,供电侧的开关器件以发热模式运行。之后在目标电池过流运行满足预设关断条件的情况下,再同时关断两个开关器件。上述方案,在发生过流时,并非直接将开关器件断开,而是继续维持其中一个开关器件导通,控制另一个开关器件以发热模式运行,通过发热吸收浪涌能量,将浪涌能量耗散在开关器件的封装结构中,直至满足预设关断条件,关断两个开关器件,实现开关器件的软关断控制,从而减缓寄生电感所产生的感生电动势对开关器件的影响,避免开关器件被击穿。
