The embodiment of the invention discloses a charging heating method and device, electronic equipment and a storage medium, and the method comprises the steps: detecting whether the temperature of a battery pack is greater than a first preset temperature or not when the battery pack is charged; when the temperature of the battery pack is greater than a first preset temperature, determining a request current of the battery pack; when the request current meets a preset condition, closing a heating relay and disconnecting a main negative relay to preheat the battery pack, and detecting whether the temperature of the battery pack is greater than a second preset temperature; if the temperature of the battery pack is greater than a second preset temperature, detecting a voltage difference between an internal total voltage and an external total voltage of the battery pack; when the voltage difference between the internal total voltage and the external total voltage of the battery pack is smaller than the preset value, the main negative relay is closed, the battery pack is charged and heated according to the preset charging strategy, and the scheme can improve the safety of charging and heating.

    本申请实施例公开了一种充电加热方法、装置、电子设备以及存储介质,包括:检测电池包在充电时,所述电池包的温度是否大于第一预设温度;当所述电池包的温度大于第一预设温度时,则确定所述电池包的请求电流;当所述请求电流满足预设条件时,则闭合加热继电器以及断开主负继电器对所述电池包进行预加热,并检测所述电池包的温度是否大于第二预设温度;若所述电池包的温度大于第二预设温度,则检测所述电池包的内总压和外总压之间的压差;当所述电池包的内总压和外总压之间的压差小于预设值时,则闭合主负继电器,并按照预设充电策略对所述电池包进行充电加热,该方案可以提高充电加热的安全性。
