The phase change material can store or release a large amount of phase change heat when the physical state changes, and the temperature range of the phase change is narrow. When the physical state changes, the temperature of the material is almost kept unchanged before the phase change is completed, and when a large amount of phase change heat is transferred to the environment, a wide temperature platform is generated, and the principle is as follows: the phase-change material stores energy in the heat transmission process, so that the energy transmission time can be prolonged like thermal resistance, and the temperature gradient is reduced. Because the phase-change material utilizes latent heat to store energy, the heat storage density is large, the heat storage device has compact structure, the temperature of the phase-change material is basically unchanged in the phase-change process, and the phase-change material is easy to manage.

When the temperature inside the shell 11 is lower than 10 ℃ or higher than 35 ℃, the semiconductor refrigeration sheet 13 starts to work and controls the temperature in cooperation with the composite filler.
The temperature control process of the device is as follows:
1. When the temperature inside the shell 11 is raised or the external environment temperature is high due to the operation of the battery pack, the phase-change material in the composite filler is changed from a solid state to a liquid state, and the heat released by the battery is absorbed, so that the temperature stability in the shell 11 is maintained. When the temperature reaches the set value of the temperature sensor, the temperature control module starts to work, the semiconductor refrigeration sheet 13 starts to refrigerate, the surface, attached to the shell 11, of the semiconductor refrigeration sheet 13 cools and absorbs heat, the surface, attached to the aluminum profile radiator 14, of the semiconductor refrigeration sheet 13 heats and releases heat, and therefore cooling of the battery pack by the semiconductor refrigeration sheet 13 is completed, and the battery pack is maintained in the optimal working temperature range.

When the temperature in the battery pack continues to decrease and the temperature sensor detects that the temperature is lower than the lower limit of the optimal temperature range, the current direction of the temperature control module is changed, the semiconductor refrigeration piece 13 starts to heat, the semiconductor refrigeration piece 13 is attached to one surface of the shell 11 to heat and release heat, and the semiconductor refrigeration piece 13 is attached to one surface of the aluminum section radiator 14 to absorb heat, so that the temperature of the battery pack is increased.
