Embodiment Construction
[0017] The invention adopts phase change material for cooling. The system design is different from the traditional air cooling system. It can make the power battery achieve the best cooling effect of the battery in the harsh thermal environment, and realize the temperature distribution between the battery cells. The balance of power equipment, so as to achieve the best operating conditions of the power equipment, ensure the stable performance of the battery stack, and play an important role in extending the battery life and improving the power performance of the power equipment.
[0018] The structure of battery cell 302 is as attached figure 1 As shown, the battery 103 is used as the base body, and the outer casing 101 is tightly fitted and sealed with insulating rubber to prevent the phase change material from overflowing during the heat storage process. The battery 103 and the casing 101 are filled with the phase change material to generate the inside of the battery. The heat ...
