The invention provides an unbalanced charging and discharging control method and device, control equipment, a battery and a storage medium, and relates to the technical field of devices for charging or depolarization of a battery pack or supplying power to a load by the battery pack. In the control equipment, the control equipment comprises a battery pack, a monitoring assembly, an adjusting assembly and an analogue simulation assembly, the battery pack comprises a plurality of battery cells, the monitoring assembly and the adjusting assembly are electrically connected with the battery cells respectively, the monitoring assembly is in communication connection with the adjusting assembly, and the analogue simulation assembly is electrically connected with the monitoring assembly. According to the scheme, the battery pack active equalization circuit is utilized, the peripheral battery cells are preferentially charged and discharged to be in a safe SOC state during charging and discharging, a fire is not prone to occurring under the condition that the external battery cells are collided and extruded, the RESS energy density is not reduced through the method, and the vehicle collision electric safety is improved under the condition that the vehicle body mechanical structure cost is not increased. In addition, the purpose of reducing the collision fire risk can be achieved only through software control.

    本发明提供一种非均衡充放电的控制方法、装置、控制设备、电池及储存介质,涉及用于电池组的充电或去极化或用于由电池组向负载供电的装置技术领域。在控制设备中,控制设备包括电池组、监测组件、调节组件和仿真模拟组件,电池组包括多个电芯,监测组件和调节组件分别与电芯电连接,监测组件与调节组件之间通信连接,仿真模拟组件与监测组件电连接。在本方案中,利用电池包主动均衡电路,在充放电时候优先将外围电芯充放电到较为安全的SOC状态,在外部电芯发生碰撞挤压情况下更不易起火,且该方法不会降低RESS能量密度,在不增加车身机械结构成本情况下提升了车辆碰撞电安全。而且,本申请只需通过软件控制就可达成降低碰撞起火风险的目的。
