Abstract: Auxiliary power is provided to an auxiliary heating, ventilation and air conditioning (HVAC) subsystem located compactly beneath the passenger seat of a daycab. Nickel metal hydride (NiMH) or suitably alternative battery power is inverted to drive the HVAC subsystem, and the batteries are charged from the daycab's alternator when the daycab's engine is running or from a roadside power grid when the daycab is idle.

Abstract: A fuel-efficient auxiliary power generation, conversion, and supply system is configured within the periphery of a vehicular conveyance, and typically including a plurality of batteries, a power generator, an internal combustion engine, and an instrument control assembly including one or more inverter portions and a rectifier portion. A method for charging the batteries within a narrow hysteresis voltage range to reduce charging stress is described.

Abstract: A fuel-efficient auxiliary power generation, conversion, and supply system configured within the periphery of a vehicular conveyance, and typically including a plurality of batteries, a power generator, an internal combustion engine, and an instrument control assembly including an inverter portion and a rectifier portion. The system generally comprises a portion of an electrical circuit substantially independent from a primary operative electrical circuit of the vehicular conveyance, and the combustion engine operates independently from a primary operative engine of the vehicular conveyance.
