Abstract

Abstract Disclosed is a system for charging a battery at locations where fluid under pressure is readily available. The fluid under pressure flows through an intake line containing a filter, lubricator, regulator assembly, a pressure switch and a valve to a fluid actuated motor which drives an alternator electrically coupled to a battery. A sensing unit is electrically coupled to the alternator, valve and battery. When the battery requires charging, the sensing unit senses the voltage and electrically opens the valve and energizes the alternator field simultaneously, whereby fluid under pressure drives the fluid motor and the alternator to recharge the battery. When the battery is fully charged the sensing unit electrically closes the valve and opens the field circuit on alternator, thereby cutting off the supply of fluid under pressure to the fluid motor which, in turn shuts down the alternator. In the event that the fluid under pressure is cut off, the pressure switch opens to electrically disconnect the alternator, solenoid valve and sensing unit to preclude power drain thereto from the battery and allows the battery charge to be used only for the load circuit.
