The average daily energy consumption of the conventional air conditioning is 20.8 % in battery charging and discharging mode and 58.4 % in standby mode. The proposed container energy storage temperature control system has an average daily energy consumption of 30.1 % in battery charging and discharging mode and 39.8 % in standby mode. Fig. 10.
The maximum cell temperature difference of the optimized battery thermal management system was reduced by 1.7 K with the power consumption decreased by 12 %. Luo et al. developed an X-type double inlet and outlet symmetrical air-cooled battery thermal management system.
Fig. 1 (a) shows the schematic diagram of the proposed composite cooling system for energy storage containers. The liquid cooling system conveys the low temperature coolant to the cold plate of the battery through the water pump to absorb the heat of the energy storage battery during the charging/discharging process.
Containerized energy storage systems play an important role in the transmission, distribution and utilization of energy such as thermal, wind and solar power [3, 4]. Lithium batteries are widely used in container energy storage systems because of their high energy density, long service life and large output power [5, 6].
The proposed energy storage container temperature control system provides new insights into energy saving and emission reduction in the field of energy storage.
The difference between individual cells reduces to nearly 5–7 °C, resulting in a perceptible drop in temperature for each cell.
Here, the cooling load depends on the difference between the maximum operating temperature of the battery (such as 35°C, 40°C, 45°C, 50°C) and the initial temperature of 25°C (∆T).
