Abstract

The electric vehicle is a kind of complex mechatronics product. In order to realize the connection of various components in the compact space, the busbar is required for electric vehicles to have the higher power transmission function. The carrying capacity under different environment temperatures is studied. The mathematical model of carrying capacity and temperature of busbar is established by changes of electrical and thermal conductivity on temperature, combined with the heat transfer principle. The influence of environment and operating temperature on the carrying capacity of different busbar specifications is analyzed. When the environment temperature is 40℃ and the operating temperature is 70℃, no matter how the busbar type changes, the average deviation of carrying current is less than 3.32%, the maximum deviation is only 4.19%, and the error is only (3.38±0.82) %, which indicated that the mathematical model is accurate. When the operating temperature is constant, the carrying capacity decreases obviously as the environment temperature increases. When the operating temperature is 70℃, the carrying capacity of busbar at 40℃ is reduced by 15.59% compared with that at 25℃. When the cross-sectional area of busbar increases, its carrying capacity increases obviously. And when the cross-sectional area is the same, with the increase of the heat dissipation area of busbar, its carrying capacity also increases significantly, which is independent of the environment temperature. When the heat dissipation area is increased from 136mm² to 172mm² , the carrying capacity of busbar at 110℃ of the operating temperature is increased by 12.46%.
