The invention relates to a battery fault detection method and device, electronic equipment, a computer readable storage medium and a computer program product. The method comprises the following steps: acquiring voltage data obtained by performing voltage acquisition on each battery cell of a battery pack through a sampling wire harness; if it is judged that the battery pack has the voltage fault according to the voltage data, an extreme value difference is calculated according to the voltage data; and if the extreme value difference is smaller than or equal to the preset voltage threshold value, determining that the sampling wire harness has a fault, and maintaining the working state of the battery pack. When the battery pack is judged to have a voltage fault in combination with the voltage data collected by each battery cell of the battery pack, the extreme value difference is calculated according to the voltage data, if the extreme value difference is smaller than or equal to the preset voltage threshold value, the sampling wire harness fault is judged, the working state of the battery pack is maintained, the use of the battery pack is prevented from being influenced by the sampling wire harness fault, and the safety of the battery pack is improved. And the power supply convenience is improved.

    本申请涉及一种电池故障检测方法、装置、电子设备、计算机可读存储介质和计算机程序产品,该方法包括:获取通过采样线束对电池包各电芯进行电压采集得到的电压数据;若根据电压数据判断电池包存在电压故障,则根据电压数据计算得到极值差;若极值差小于或等于预设电压阈值,则判定为采样线束故障,维持电池包的工作状态。在结合对电池包各电芯采集到的电压数据判断电池包存在电压故障时,根据电压数据计算得到极值差,若极值差小于或等于预设电压阈值,则判定为采样线束故障,维持电池包的工作状态,避免因采样线束故障影响电池包的使用,提高了供电便利性。
