Description

technical field [0001] The invention provides a temperature-adjustable electric vehicle battery compartment, in particular to a device capable of controlling the temperature of the battery compartment through wind energy, solar energy and battery electric energy, and belongs to the technical field of battery cooling equipment. Background technique [0002] The battery is the main energy storage device of electric vehicles. The battery temperature not only has a certain impact on its discharge power, charging receiving capacity, and operability, but also greatly affects the life of the battery. Suitable operating temperature range is an important factor for optimal battery performance and extended service life. When the power battery is charged and discharged, it will generate electrochemical reaction heat and Joule heat, which will increase its own temperature. When the upper limit of its optimal operating temperature is exceeded, the performance of the power battery will be...

AI Technical Summary

Problems solved by technology

Air cooling is the most widely used heat dissipation method. Forced airflow is generated by the operation of a fan or by using the headwind of the car while driving; liquid cooling uses a fluid with a relatively high thermal conductivity to indirectly or directly contact the battery to dissipate heat. The heat transfer coefficient between the walls, but it will face the possibility of liquid leakage, and the repair and maintenance are complicated; the cooling of the cold plate is to use the cold plate between the modules to improve the heat dissipation efficiency and the uniformity of the temperature between the modules, which can be well strengthened Local heat dissipation, but it will increase the volume and cost; phase change materials and heat pipes use the latent heat when the object changes phase to store or release energy, although it can alleviate the heating of the battery, but it increases the cost and weight of the system
