The invention provides a battery charging and discharging control method and device, a storage medium and an electric vehicle. The method comprises the steps of: detecting whether the temperature difference between the surface temperature of a battery and the environment temperature reaches a preset temperature threshold or not and/or whether the charging duration of the battery reaches a first preset duration or not in a battery charging process, if the temperature difference is detected to reach a preset temperature threshold and/or the charging duration is detected to reach a first preset duration, controlling a charging line of the battery to be disconnected to prevent overcharging, and/or in the discharging process of the battery, detecting whether the second voltage at the two ends of the battery reaches a preset discharging cut-off voltage and/or whether the discharging duration of the battery reaches a second preset duration or not, and if the second voltage is detected to reach a discharge cut-off voltage and/or the discharge duration is detected to reach a second preset duration, controlling a discharge line of the battery to be disconnected. According to the scheme provided by the invention, judgment can be carried out before overcharge and overdischarge of the battery of the electric vehicle, and overcharge and overdischarge of the battery are prevented.

    本发明提供一种电池充放电控制方法、装置、存储介质及电动汽车,所述方法包括:在电池充电过程中,检测所述电池的表面温度与环境温度的温差是否达到预设温度阈值和/或所述电池的充电时长是否达到第一预设时长;若检测到所述温差达到预设温度阈值和/或所述充电时长达到第一预设时长,则控制所述电池的充电线断开以防止过充;和/或,在所述电池的放电过程中,检测所述电池两端的第二电压是否达到预设的放电截止电压和/或所述电池的放电时长是否达到第二预设时长;若检测到所述第二电压达到放电截止电压和/或所述放电时长达到第二预设时长,则控制所述电池的放电线断开。本发明提供的方案能够在电动汽车电池过充、过放前进行判断,防止电池出现过充、过放。
