Modern applications require the storage of electricity via batteries. Batteries that are kept in isolation or a closed compact space, such as power plants or electric vehicles, tend to heat up dramatically, resulting in a depreciation of efficiency as well as battery lifetime. There are two factors that primarily determines the battery's temperature. The charging and discharging of the battery are the factors that cause heat generation in the battery. This heat is dissipated by the battery during charging and discharging is controlled by a Liquid Cooling System and liquid Heat Exchanger. The Heat Exchanger connected to the Battery System exchanges the fluid heat, which is used to exchange the heat of the liquid around the battery layer externally. A Battery Thermal Management System that regulates the temperature of the battery within the desired range will reduce the power consumption while increasing charge storing capacity and battery life.
