The invention relates to a battery equalization control method, electronic equipment, a battery management system and an engineering vehicle, and the method comprises the steps: determining a target battery cell which is a battery cell needing to be equalized in a battery; the method comprises the following steps: acquiring a target temperature, and determining a corresponding target PWM duty ratio according to the target temperature, the target temperature being the maximum temperature of a plurality of battery monitoring modules, and further controlling the battery monitoring modules to perform equalization control on a target battery cell according to the target PWM duty ratio. Therefore, the PWM duty ratio for performing equalization control on the corresponding battery cell is dynamically adjusted by utilizing the temperature on the battery monitoring module, so that thermal runaway caused by over-high temperature rise can be avoided while the equalization effect is ensured, the consistency of the battery cells in the battery is effectively improved, and the service life of the battery is ensured.

    本申请涉及一种电池均衡控制方法、电子设备、电池管理系统及工程车辆,电池均衡控制方法包括:确定目标电芯,目标电芯为电池中需要进行均衡的电芯;获取目标温度,并根据目标温度,确定对应的目标PWM占空比,其中,目标温度为多个电池监控模块上的最大温度,进而控制电池监控模块按照目标PWM占空比,对目标电芯进行均衡控制。如此,利用电池监控模块上的温度动态调整对相应电芯进行均衡控制的PWM占空比,可以在保证均衡效果的同时,避免温升过高而导致热失控,从而有效提升了电池中电芯的一致性,保障了电池的寿命。
