Construction of temperature control solution for energy storage system

What is battery thermal management & cooling?

Thermal management and cooling solutions for batteries are widely discussed topics with the evolution to a more compact and increased-density battery configuration. A battery thermal-management system (BTMS) that maintains temperature uniformity is essential for the battery-management system (BMS).

Which thermal management applications require active liquid cooling?

At the high end, the most demanding thermal management applications, such as large-scale BESS installation and high C-rate applications, require active liquid cooling. On the other end of the spectrum, smaller installations with low C-rate applications can be safely and efficiently operated at peak performance with air cooling.

What are the strategies of temperature control for BTMS?

The strategies of temperature control for BTMS include active cooling with air cooling, liquid cooling and thermoelectric cooling; passive cooling with a phase-change material (PCM); and hybrid cooling that combines active and passive cooling . Studies of the BTMS involve battery modeling and the investigation of the cooling solutions.

How does a cooling strategy improve temperature inhomogeneity?

This new cooling strategy improved the temperature inhomogeneity by reducing the temperature uniformity between cells by 3.2 °C and by reducing the consumed cooling flow by 38 %. Shi et al. investigated the effect of setting the air inlet on the side wall of the battery pack to the internal temperature field.

Does airflow organization affect heat dissipation behavior of container energy storage system?

In this paper, the heat dissipation behavior of the thermal management system of the container energy storage system is investigated based on the fluid dynamics simulation method. The results of the effort show that poor airflow organization of the cooling air is a significant influencing factor leading to uneven internal cell temperatures.

Why is air-cooling important for battery thermal management?

For various cooling strategies of the battery thermal management, the air-cooling of a battery receives tremendous awareness because of its simplicity and robustness as a thermal solution for diverse battery systems. Studies involve optimizing the layout arrangement to improve the cooling performance and operational efficiency.
