Cylindrical lithium battery management system

What are the thermal management strategies used in cylindrical lithium-ion battery packs?

This paper presents a comprehensive review of the thermal management strategies employed in cylindrical lithium-ion battery packs. The review covers four major thermal management techniques: air cooling, liquid cooling, phase-change materials (PCM), and hybrid methods.

What is a cylindrical lithium-ion battery module?

Peng et al. devised a cylindrical lithium-ion battery module featuring a compact hybrid cooling system integrating PCM and heat pipes. The batteries are closely arranged, and the vacant spaces between them are filled with either heat pipes or PCM tubes, as illustrated in Figure 23.

Do lithium-ion batteries need a thermal management system?

To tackle these issues, lithium-ion batteries can be fitted with a battery management system (BMS) that oversees the regular functioning of the battery and optimizes its operation. Ensuring the safe functioning and extending the lifespan of a battery necessitates the presence of an efficient thermal management system.

Can a composite thermal management system overcome temperature increase in lithium-ion battery?

To overcome the temperature increase of battery along the flow direction of coolant in cylindrical lithium-ion battery module, a composite thermal management system integrated with mini-channel liquid cooling and air cooling is proposed.

How to manage the thermal challenges of lithium-ion batteries?

Additionally, the system should consider aspects such as thermal insulation to mitigate cold temperature effects and the prevention of thermal runaway events, emphasizing the importance of a comprehensive and multifaceted approach in managing the thermal challenges of lithium-ion batteries.

Are cylindrical and square batteries suitable for thermal management systems?

At present, cylindrical and square batteries are widely used in battery thermal management systems. There is little research on liquid-cooled BTMS for cylindrical batteries because they have a curved surface compared to square batteries and it is more challenging to install heat exchangers on their surface.
