The invention relates to a passive equalization control method and device, computer equipment and a storage medium. The method comprises the following steps: under the condition that the maximum monomer voltage difference of a power battery meets a passive equalization starting condition, controlling a preset number of equalization resistors to access the power battery so as to start passive equalization of the power battery; monitoring a battery temperature rising process of the power battery, determining a plurality of rising stages included in the battery temperature rising process according to a plurality of gradually increased adjusting temperature thresholds under the condition that the battery temperature of the power battery is not less than a first adjusting temperature threshold, and determining a plurality of rising stages included in the battery temperature rising process according to a battery temperature rising rate before each adjusting temperature threshold. Determining the access number of the equalization resistors corresponding to each rising stage, and controlling the equalization resistors of the corresponding number to access a circuit where the power battery is located in each rising stage; and under the condition that the maximum monomer voltage difference meets the passive equalization completion condition, all equalization resistors are controlled to be disconnected so as to stop passive equalization of the power battery.

    本申请涉及一种被动均衡控制方法、装置、计算机设备和存储介质。所述方法包括:在动力电池的最大单体压差满足被动均衡启动条件的情况下,控制预设数量的均衡电阻接入动力电池,以启动对动力电池的被动均衡;监测动力电池的电池温度上升过程,在动力电池的电池温度不小于第一个调节温度阈值的情况下,根据多个逐渐增大的调节温度阈值,确定电池温度上升过程包括的多个上升阶段,根据每一个调节温度阈值之前的电池温度上升速率,确定每一个上升阶段对应的均衡电阻的接入数量,并在每一个上升阶段中控制相应数量的均衡电阻接入动力电池的所在电路;在最大单体压差满足被动均衡完成条件的情况下,控制全部均衡电阻断开,以停止对动力电池的被动均衡。
