Abstract
The utility model discloses a heating preservation structure for a power battery, which comprises a battery cell group, a large heat capacity inner shell, an insulating layer and an outer shell. The large heat capacity inner shell is provided with an installing inner cavity for the battery cell group. The insulating layer is filled between the large heat capacity inner shell and the outer shell. The battery cell group is formed by parallelly connecting battery individual members. The battery individual members are evenly distributed in an inner cavity of the large heat capacity inner shell at intervals. Air ducts are formed by gaps among the battery individual members evenly distributed at intervals. When the battery cell group works, the battery discharges electricity to heat inside battery cells, and outside hot blast enters the battery cell group through the air ducts. Because of having small heat capability and faster heat transfer, the battery cells are firstly heated by the discharging heat of the battery and the outside air blast and the temperature of the working environment can be met by the battery cells more quickly. The heat discharged by the battery cell group is absorbed by the large heat capacity inner shell. The insulating layer has small heat transfer coefficient, thereby ensuring the safe conservation of the inside heat. The heating preservation structure for the power battery has the advantages that the temperature inside the battery cell group cools down slowly, and the temperature of the battery cells warms rapidly, so that when the environment temperature is lower, the discharging heat of the battery and the outside hot blast can be fully used. When the environment temperature is higher, the entry of the outside heat can be effectively prevented.
