| Summary: | This article presents the impact of abuse discharge condition on the battery cell surface temperature. The abuse discharge condition is when the battery is discharge down to 10% State of Charge (SOC). To determine the temperature evolution of the battery cell surface, a series of experiments is conducted. Three battery cells in a battery pack are discharged at 1C, 3C, and 5C discharge rate with a constant cooling air velocity of 2 m/s. The battery is discharge from 100% SOC down to 10% SOC to simulate the abuse discharge condition. Experimental results show that discharging the battery at SOC lower than 20% contributes to a radical increase of cell temperature at all battery cell locations impacted by a sudden increase of internal resistance's value in this region. |
