Abstract
A distributed charging system for electric and hybrid electric vehicles includes multiple battery packs of different voltages including high voltage battery packs and one or more low voltage battery packs, each having separate and independent charging systems and multiple sources of electric power. Electric power is distributed from the sources of electric power separately to each of the independent charging systems. A drive system for the electric or hybrid electric vehicle includes a stored energy system made up of these multiple battery packs and a master events controller controlling at least one of a) a traction drive system including a motor and controller for receiving driving electric energy from a stored energy system for propulsion of the vehicle, b), an auxiliary power system for recharging the battery packs and c) a vehicle monitoring and control network for controlling the operation of, and monitoring all bus systems in the vehicle.
