Energy storage battery heat dissipation

Does a lithium-ion battery have thermal management and heat dissipation attributes?

This paper focuses on the thermal management and heat dissipation attributes of a lithium-ion battery assembly within a military hybrid armored vehicle stationed at an altitude of 4000 m. Firstly, a comprehensive three-dimensional thermal model was constructed for the battery unit to establish an air-cooled dissipation framework.

When does a battery pack need additional heat dissipation methods?

Beyond this threshold, alternative heat dissipation methods become necessary to maintain the battery pack within the optimal temperature range. When the discharge rate is greater than 1.6 C, additional heat dissipation methods are required to maintain the battery pack within the optimal temperature range.

How does a lower inlet temperature affect battery heat dissipation?

An increased heat exchange rate is more beneficial to the battery heat dissipation. Although a lower inlet temperature can increase the heat dissipation, the parasitic energy consumption needed by the cooling water in the refrigeration system would be higher, which needs further to be balanced. Figure 7.

Why is heat dissipation of power batteries important?

Especially for new military combat equipment in China, such as hybrid armored vehicles, effective heat dissipation of power batteries is essential for their operational viability in intricate plateau terrains.

How does air cooled heat dissipation affect battery discharge rate?

However, the rate of temperature decrease gradually slows down as the inlet velocity increases. Additionally, forced air-cooled heat dissipation can only maintain the temperature of battery packs within an optimum range for discharge rates of up to 1.6 C. Murshed SMS, De Castro CAN.

How to prevent thermal runaway of lithium-ion batteries?

For the prevention of thermal runaway of lithium-ion batteries, safe materials are the first choice (such as a flame-retardant electrolyte and a stable separator, 54 etc.), and efficient heat rejection methods are also necessary. 55 Atmosphere protection is another effective way to prevent the propagation of thermal runaway.
