The invention discloses a battery equalization control method, device and equipment and a storage medium, and relates to the technical field of batteries, and the method comprises the steps: collecting the voltage and temperature of each battery cell corresponding to each single battery cell; based on the voltage of each battery cell, judging whether equalization control needs to be carried out on each single battery cell or not; and when it is determined that equalization control needs to be performed on each single cell, based on the voltage of each cell and the temperature of each cell, starting a corresponding one of the active equalization circuit and the passive equalization circuit to perform equalization control on each single cell. Whether equalization control needs to be carried out on each single battery cell is judged by acquiring each battery cell voltage and each battery cell temperature of each single battery cell in a plurality of battery packs which are connected in series, and a specific mode for carrying out equalization control on each single battery cell at present is selected according to each battery cell voltage and each battery cell temperature. Therefore, the equalization control mode can be adaptively adjusted under the condition of temperature change, and different requirements corresponding to equalization control in different scenes are met.

    本申请公开了一种电池均衡控制方法、装置、设备及存储介质,涉及电池技术领域,该方法通过采集各单体电芯对应的各电芯电压以及各电芯温度;基于各电芯电压,判断是否需要对各单体电芯进行均衡控制;在判定需要对各单体电芯进行均衡控制时,基于各电芯电压以及各电芯温度,开启主动均衡电路或被动均衡电路中对应的一个对各单体电芯进行均衡控制。通过获取相互串联的多个电池组内各单体电芯的各电芯电压以及各电芯温度来判断是否需要对各单体电芯进行均衡控制,并通过各电芯电压以及各电芯温度来选择当前对各单体电芯进行均衡控制的具体方式,从而能够在温度变化的情况下自适应地调整均衡控制方式,满足不同场景下进行均衡控制对应的不同需求。
