     The vehicle will generate heat during driving. Whether it is a traditional fuel vehicle or a new energy vehicle, the components of the heat generated are different due to different structures. Although the new energy vehicle has no engine, it is no exception. The new energy vehicle will also generate heat during driving, and its heat is different from that of the traditional fuel vehicle, The heat generated by new energy vehicles comes from the power battery. The power battery has large working current and large heat production. At the same time, the battery pack is in a relatively closed environment, which will lead to the temperature rise of the battery.

      Too high or too low temperature will accelerate the attenuation of battery life. Generally, the appropriate temperature is about 10 30 degree C. So, many people ask how the battery of electric vehicles dissipates heat?  According to the heat dissipation medium, it is divided into air cooling and liquid cooling.

    Most cars basically use liquid cooling. In short, liquid cooling is to flow the battery cell through the liquid in the internal coolant cooling pipe, and take away all the heat generated by the cell after flowing through the coolant. The strong specific heat capacity of the coolant absorbs the heat generated during the operation of the cell, so that the whole battery pack operates at a safe temperature.

     Secondly, air cooling uses gas (air) as the heat transfer medium. From the structural point of view, a cooling fan is installed at one end of the battery pack, and a corresponding ventilation hole is reserved at the other end of the battery. When the air blown by the cooling fan passes through the gap hole reserved by the battery cell, through the role of air volume, the wind can accelerate the flow, So as to take away the high heat generated by the electric core during operation; Keep the battery temperature within a reasonable range, and the working and storage temperature of lithium battery will also indirectly affect the service life.
