The embodiment of the invention provides a battery equalization enabling method and device, a storage medium and a battery pack. Whether an equalization instruction is received or not is judged; if itis judged that the equalization instruction is not received, whether the cell type of a single battery comprises a lithium iron phosphate cell or not is judged; if it is judged that the cell type comprises the lithium iron phosphate cell, whether the measured change value of the state of charge of the single battery is smaller than a specified threshold value or not is judged; if the change valueof the state of charge is judged to be smaller than the specified threshold value, whether the obtained residual equalization capacity of the single battery is greater than a set calibration capacityor not is judged; and if it is judged that the residual equalization capacity is greater than the calibration capacity, equalization enabling is performed on the single battery. In the embodiment ofthe invention, when the change value of the state of charge of the single battery of the lithium iron phosphate cell is smaller than the specified threshold value and the residual equalization capacity is greater than the calibration capacity, equalization enabling is carried out on the single battery, so that the starting frequency of battery equalization enabling is improved, and the equalization effect of the battery is improved.

    本发明实施例提供了一种电池均衡使能方法、装置、存储介质和电池包。通过判断是否接收到均衡指令;若判断出未接收到均衡指令,判断电池单体的电芯类型是否包括磷酸铁锂电芯;若判断出电芯类型包括磷酸铁锂电芯,判断测量出的电池单体的荷电状态的变化值是否小于指定阈值;若判断出荷电状态的变化值小于指定阈值,判断获取的电池单体的剩余均衡容量是否大于设置的标定容量;若判断出剩余均衡容量大于标定容量,对电池单体进行均衡使能。本发明实施例中,当磷酸铁锂电芯的电池单体的荷电状态的变化值小于指定阈值且剩余均衡容量大于标定容量时,对电池单体进行均衡使能,提升了电池均衡使能的开启频次,从而提高了电池的均衡效果。
