The temperature is an important factor affecting the performance, safety and cycle life of LiFePO4 power batteries. It is very important to measure the thermo-physical properties of batteries and study the temperature rise characteristic in the design of battery thermal management. The specific heat capacity, heat generation rate and thermal conductivity of the LiFePO4 power battery with the fixed capacity of 20 Ah were experimental y measured. The temperature rise characteristic of the battery at 1 , 2 and 3 with forced cooling were studied out. The results wil provide important theory basis for the thermal design of the battery.
