Abstract
Laminated structure is widely used in traction lithium ion battery to improve battery capacity and reduce volume. Current collecting tabs are placed at the top area of battery in laminated structure, which would inevitably led to uneven temperature distribution inside battery. A two-dimensional thermal model of 20 Ah LiFePO4 battery is established to study the uneven spatiotemporal characteristic of temperature distribution. The simulation result agrees well with the experimental data, and validates the efficiency of the thermal model. This model can be further used in the optimization of battery structure as well as the battery thermal sensor location selection strategy.
