Description

When needed, the stored electric energy will be output. When the energy storage cabinet is charged and discharged, heat will be generated. Controlling the battery within a reasonable temperature range and ensuring that the temperature difference of the battery in the energy storage cabinet is within a certain range can improve the performance and safety of the battery. However, since the energy storage cabinet contains many battery cells, a large amount of heat is generated during charging and discharging.
