Interest in electric vehicles (EVs) and hybrid electric vehicles (HEVs) is growing steadily as battery technologies improve and the driving range of such vehicles increases. Perhaps as important, EVs/HEVs offer a “green” alternative to traditional vehicles powered by internal-combustion gasoline engines. EVs and HEVs rely on robust electric motor drives, large-capacity battery pack, power inverters, and efficient distribution of power from charging source to battery and then throughout the vehicle. Busbars, which comprise a system of electrical conductors for collecting and distributing current, provide the means to efficiently distribute power to the vehicles’ various subsystems. A number of different types of busbars are commercially available, so specifying the best match for an EV/HEV application is a matter of understanding the various requirements of an EV/HEV and how different types of power busbars can meet those requirements.
