The invention discloses a battery equalization method and device, control equipment and a computer readable storage medium, and the method comprises the steps: determining a to-be-equalized single battery in a battery pack when the current working condition of a vehicle is judged to be a stable working condition, and calculating the predicted equalization electric quantity difference of the to-be-equalized single battery; and carrying out equalization processing on the to-be-equalized single battery according to the predicted equalization electric quantity difference when the vehicle is in anyworking condition. According to the invention, the equalization control is not limited by the working condition, when the vehicle is in the driving working condition for a long time, the equalizationprocessing can still be carried out, the full equalization of the single batteries can be realized, and the problem that the equalization requirement cannot be met due to insufficient equalization working condition in the prior art is avoided; on the other hand, periodic equalization measurement is not needed, only one predicted value is needed as a target to perform equalization processing on the to-be-equalized single battery, the equalization process and the measurement process are decoupled, and the robustness of equalization prediction and control is improved.

    本发明公开了一种电池均衡方法及装置、控制设备、计算机可读存储介质,所述电池均衡方法包括:当判断车辆当前所处的工况为稳定工况时,确定电池包内的待均衡单体电池,计算所述待均衡单体电池的预测均衡电量差;在所述车辆处于任意工况下,根据所述预测均衡电量差对所述待均衡单体电池进行均衡处理。本发明的均衡控制不受工况的限制,当车辆长期处于行车工况时,仍然能进行均衡处理,则可实现单体电池的充分均衡,避免现有技术均衡工况不充裕而无法满足均衡要求的问题;另一方面,本发明无需周期性地进行均衡测量,仅需要一个预测值作为目标对待均衡单体电池进行均衡处理,均衡过程和测量过程实现解耦,提高均衡预测和控制的鲁棒性。
