Problems solved by technology

The battery box for new energy vehicles generally includes the box body and the battery pack inside it. When using it, it is necessary to ensure that the ambient temperature around the battery pack is between 20 and 25 degrees, otherwise it will affect the normal charging and discharging of the battery, and the environment will be affected. The first method of temperature control is to cool down, because the battery will definitely generate heat during the charging and discharging process, which will cause the temperature of the surrounding environment to rise sharply
