Abstract：The temperature rise and distribution of Ni-MH battery pack during its charging and discharging were studied. Considering the larger initial charging current due to the battery temperature rise a phased constant current charging control strategy was proposed. By analyzing the theoretical temperature fields model, the cooling structure of the original battery pack was optimized, and a phased joint control of constant current charging strategy was proposed. Then, a simulation of the battery thermal management control method was conducted and a test bench was setup about the battery pack temperature fields in the computing environment of Matlab／Simulink and Fluent. The test results verifed the advantages of the battery thermal management control method that we proposed.
