The invention provides a heat recycling and reusing method, device and equipment during battery charging and a vehicle. When a battery pack is in a charging state, when it is detected that the temperature of the battery pack is lower than a first target temperature, and the temperature of a heat recycling device and the temperature of an engine do not meet heating conditions, the battery pack is charged; whether the engine temperature and/or the heat recovery device temperature are/is larger than the second target temperature or not is judged, and when it is detected that the engine temperature and/or the heat recovery device temperature are/is larger than the second target temperature, the engine with the temperature larger than the second target temperature or the heat recovery device with the temperature larger than the second target temperature is selected as a heat source; and the heat source is controlled to heat the battery pack, in order to prevent the battery pack from being damaged by high temperature, the water temperature at the inlet of the battery pack does not exceed the fourth target temperature in the heating process, and the safety of the battery pack in the heating process is ensured while the recycled heat is recycled.

    本发明提供一种电池充电时的热量回收再利用方法、装置、设备和车辆,在电池包处于充电状态时,当检测到电池包温度低于第一目标温度时,且所述热量回收装置温度和发动机温度均不满足加热条件时,判断所述发动机温度和/或所述热量回收装置温度是否大于所述第二目标温度时,当检测到所述发动机温度和/或所述热量回收装置温度大于所述第二目标温度时,选择大于所述第二目标温度的所述发动机或者是热量回收装置作为热源,控制热源对所述电池包进行加热,为了防止电池包被高温损坏,在加热过程中保持所述电池包入口水温不超过第四目标温度,在对回收热量进行再利用的同时,保证了电池包加热过程中的安全性。
