ABSTRACT:
A DC powered compressor system that uses a series of 12 volt batteries to provide multiple units of 12 volts power to a compressor motor as needed. A circuit arrangement comprises: a series of 12 volt batteries, a charging unit for the batteries when they are not powering the motor, and several switches to connect the batteries to the compressor motor when low pressure is detected. The arrangement allows the batteries to power the motor with a voltage equal to the sum of the batteries in series when low pressure in the compressor is detected and to allow a charging unit to charge the batteries when the motor is not being powered. A pressure switch in connection with the tank of the compressor activates the switches which disconnect the batteries from the charger and reconnects them to the motor upon detecting a drop in pressure in the tank.
