There are two design goals for the thermal management system of the power lithium battery: 1) Keep the inside of the battery pack within a reasonable temperature range; 2) Ensure that the temperature difference between different cells is as small as possible. In the design of a project, the first step must be to clarify the customer's needs.
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.
The surface cooling technology of power battery pack has led to undesired temperature gradient across the cell during thermal management and the tab cooling has been proposed as a promising solution. This paper investigates the feasibility of applying tab cooling in large-format lithium-ion pouch cells using the Cell Cooling Coefficient (CCC).
