Abstract

The invention relates to the field of power battery heat management, and discloses a power battery heat dissipation method based on an ionic liquid phase change material. The method comprises the following steps that heat generated by the power battery is absorbed by utilizing an ionic liquid phase change material; heat absorbed by the ionic liquid phase-change material is transferred to the air cooling box through a heat conducting piece; and then heat in the air cooling box is guided out through air flowing in the air cooling box. The heat dissipation method of the power battery is based onthe ionic liquid phase change material, absorbs heat generated by the battery under working or abnormal conditions through the phase change of the ionic liquid, and then rapidly removes the heat through a mode of combining fins and air cooling, so the heat storage capacity of the ionic liquid phase change material is recovered.

Description

technical field

[0001] The invention relates to the field of power battery heat management, in particular to a power battery heat dissipation method. Background technique

[0002] With the increasing shortage of oil resources and the increasingly severe environmental pollution problems, electric vehicles have shown outstanding advantages in reducing oil resource consumption, energy saving and emission reduction. In recent years, the sales of electric vehicles at home and abroad have grown rapidly.

[0003] The power battery is the core component of electric vehicles, and its performance directly determines the efficiency and safety of electric vehicles. In order to ensure the efficiency and safety of the power battery, its temperature must be strictly controlled. If the temperature of the battery pack is too high, it will accelerate the aging of the electrolyte, electrodes and other materials, and reduce the electrochemical performance of the battery. It will seriously aff...
