The energy storage batteries are centrally placed in the battery container, and the optimal operating environment temperature of the battery is 25±5℃. When the system is running, due to the internal resistance loss of the battery itself, the battery heats up and causes the temperature in the box to rise. It is necessary to use an air conditioner to control and adjust the indoor temperature, and it is necessary to ensure that the temperature deviation of all cells in the room does not exceed 5 °C. Using different forms of air conditioners, the results of room temperature control and the results of maintaining the consistency of cell temperature are also very different.
