The invention provides a battery charging control method, a battery management device and an automobile, and the battery charging control method comprises the steps: obtaining the current cycle index of a battery, and determining a charging voltage upper limit, corresponding to the current cycle index, of the battery according to the current cycle index, a plurality of preset cycle ranges and a preset charging voltage; therefore, the battery has different charge states corresponding to different preset cycle ranges, and the charge states are correspondingly large when the cycle index is large, so that the positive electrode of the battery can exert similar capacities in the corresponding different preset cycle ranges, and the capacity of the battery in the whole service life process can be ensured. The health state of the battery cannot be obviously attenuated, and the technical problem that the service power capacity of the battery is obviously reduced is solved. The battery management apparatus includes a processor configured to execute instructions to implement a battery charge control method; the automobile comprises the battery management device.
本发明提供一种电池充电控制方法、电池管理装置及汽车,电池充电控制方法通过获取电池的当前循环次数,并根据当前循环次数、多个预设循环范围与预设充电电压的关系,确定电池与当前循环次数对应的充电电压上限,以使得电池对应不同的预设循环范围具有不同的荷电状态,以在循环次数较大时,荷电状态也对应较大,继而保证电池正极在对应不同的预设循环范围均发挥相近的容量,以此保证电池在整个寿命过程中,电池健康状态可以不发生显著的衰减,改善电池使用功率能力显著下降的技术问题。电池管理装置包括被配置为执行指令以实现电池充电控制方法的处理器;汽车包括电池管理装置。
