6 FAQs about [Lithium battery pack temperature collection]

Why do we need a cooling system for lithium-ion battery pack?

The stable operation of lithium-ion battery pack with suitable temperature peak and uniformity during high discharge rate and long operating cycles at high ambient temperature is a challenging and burning issue, and the new integrated cooling system with PCM and liquid cooling needs to be developed urgently.

What are the thermal requirements of battery packs?

The thermal requirements of battery packs are specific. Not only the temperatures of the battery cells are important but also the uniformity of the temperature inside the battery cell and within the battery pack are key factors of consideration, in order to deliver a robust and reliable thermal solution.

What temperature should a Li-ion battery pack be charged at?

Unlike most electronic integrated circuits and microchips in electric vehicles, which operate best at -40˚C to 85˚C or higher, the optimal temperature range for li-ion battery packs is quite narrow and varies depending upon cell supplier, charge and discharge mode and other factors.

How to ensure stable operation of lithium-ion battery under high ambient temperature?

To ensure the stable operation of lithium-ion battery under high ambient temperature with high discharge rate and long operating cycles, the phase change material (PCM) cooling with advantage in latent heat absorption and liquid cooling with advantage in heat removal are utilized and coupling optimized in this work.
