[0027] Notably, the multiple rows of air duct round holes 12 are provided with a wire protection coil 19 corresponding to the multiple holes of the upper battery pack, since the battery compartment air duct is located at the top of the battery pack, the uppermost row of batteries can absorb the most cold air, therefore, the wire protection coil 19 is used to block some air duct round holes 12, so that the air inlet of the upper battery pack is reduced.

[0028] Notably, the inside wall of the battery compartment 2 is fully attached with thermal insulation cotton in front, back, up, down, left and right directions, which can avoid the influence of external environment on the temperature in the compartment, and also reduce the mutual influence of the temperature of the battery compartment 2 and the electrical compartment 3.
