Abstract:
One of the challenges limiting the introduction of the battery powered vehicles is the reduced power and energy for batteries operating at low temperatures and the safety of batteries operating at high temperatures. Previous research delineated the behaviors of the batteries especially the Li-ion cell batteries that are commonly used in the vehicles. Experimental evidence reveals the intrinsic self-heating of batteries as an important put of their behaviors. The performance of batteries is usually limited at temperatures higher than -20 oC depending not only on the rates of discharges but also the thermal conditions. This thesis develops a battery holder and temperature control system to enable the study of temperature effect on battery performance.
