SYSTEMS AND METHODS FOR POWERING ACCESSORIES IN ENGINE DRIVEN VEHICLES USING AUXILIARY ENGINE POWER UNITS

摘要

An auxiliary power system provides power to auxiliary systems of an engine driven vehicle independent of whether a main engine is running. The system includes an auxiliary engine with an alternator operatively connected thereto for converting mechanical power from the auxiliary engine into electrical power. A battery is electrically connected to the alternator for receiving and storing electrical power from the alternator. An electric motor is connected to the battery for powering at least one auxiliary system of the engine driven vehicle independent of whether the main engine of the engine driven vehicle is running. An existing engine driven vehicle can be retrofitted with such a system to gain the advantages thereof.
