The invention discloses a battery charging and discharging control method and device, a storage medium and a processor. The method comprises the steps that before a power battery of the electric automobile runs, whether the temperature of the power battery is lower than a preset temperature value or not is judged; under the condition that the temperature of the power battery is lower than a presettemperature value, the preset lower limit voltage value of the charging and discharging voltage interval is reduced according to the temperature of the power battery, the adjusted charging and discharging voltage interval is obtained, and the charging and discharging voltage interval is the charging and discharging voltage interval of the power battery; and controlling the power battery to discharge in the adjusted charging and discharging voltage interval so as to supply power to the electric vehicle. According to the application, the problems that the endurance mileage of the automobile isreduced and even the automobile cannot be started due to low discharge capacity of the power battery in a normal charge-discharge voltage interval at a low temperature in related technologies are solved.

    本申请公开了一种电池充放电控制方法、装置、存储介质及处理器。该方法包括:在电动汽车的动力电池运行前,判断动力电池的温度是否低于预设温度值;在动力电池的温度低于预设温度值的情况下,根据动力电池的温度降低充放电电压区间的预设下限电压值,得到调整后的充放电电压区间,其中,充放电电压区间为动力电池的充放电电压区间;控制动力电池在调整后的充放电电压区间放电,以对电动汽车供电。通过本申请,解决了相关技术中低温时动力电池在正常充放电电压区间放电量少,导致汽车续航里程降低、甚至无法启动的问题。
