What is a battery energy storage system?

Among ESS of various types, a battery energy storage system (BESS) stores the energy in an electrochemical form within the battery cells. The characteristics of rapid response and size-scaling flexibility enable a BESS to fulfill diverse applications .

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.

What are the advantages of air thermal management system?

In the air thermal management system, conditioned air is used to exchange heat with the lithium-ion battery. Its main advantages are simple structure, low cost and high safety. The liquid as a heat exchange medium has better heat transfer performance than air and is more effective in thermal management.

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.
