Abstract: The lifetime of power batteries plays an important role in industrialization of hybrid electric vehicles, and the lifetime of power batteries is directly related with heat dispersion. Taking 6.5 A.h/144V Ni-MH battery as the research object, the battery heat mechanism is analyzed, and the heat temperature model of battery is estab lished. Further more, hybrid vehicle nickel metal hydride battery pack thermal performance test rig is built, and the heat dispersion performance of the battery box is studied; meanwhile, the influence of variable current charging or discharging on the battery temperature field is analyzed. The results show that the proposed batteries can satisfy the requirements of battery heat dispersion performance of hybrid vehicle.

Key words: hybrid electric vehicles (HEV), Ni-MH cell;cooling system, temperature field
