What are the cooling strategies for lithium-ion batteries?

Four cooling strategies are compared: natural cooling, forced convection, mineral oil, and SF33. The mechanism of boiling heat transfer during battery discharge is discussed. The thermal management of lithium-ion batteries (LIBs) has become a critical topic in the energy storage and automotive industries.

What is direct liquid-cooling technology for battery thermal management?

Recently, the direct liquid-cooling technology for battery thermal management has received significant attention. The heat generated from the battery is absorbed directly by sensible (single-phase) cooling or latent heat (two-phase) cooling of the liquid with no thermal contact resistance.

Does liquid-cooling reduce the temperature rise of battery modules?

Under the conditions set for this simulation, it can be seen that the liquid-cooling system can reduce the temperature rise of the battery modules by 1.6 K and 0.8 K at the end of charging and discharging processes, respectively. Fig. 15.

Can lithium batteries be cooled?

A two-phase liquid immersion cooling system for lithium batteries is proposed. Four cooling strategies are compared: natural cooling, forced convection, mineral oil, and SF33. The mechanism of boiling heat transfer during battery discharge is discussed.

Why do batteries need a cooling system?

The cooling limitation of local battery cells also increases the risk of excessive temperature for the batteries. Thermal management and cooling solutions for batteries are widely discussed topics with the evolution to a more compact and increased-density battery configuration.

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).
