Abstract
A portable battery charger that is powered by a gasoline, diesel, or propane engine. The portable device incorporates a recoil or electric starter and an engine throttle lever that can be used to vary the RPM of the engine and therefore the voltage/current output of the charger. The charger uses a permanent magnet alternator equipped with a belt tension adjustor arm and a heavy duty diode rectifier. The components of the charger (the engine and the alternator) are positioned on a wheeled, heavy-gauge steel, roll around cart that makes the charger easily portable. The two-wheeled cart includes an extended handle, allowing the user to move and steer the charger into position for use. Positioned on this handle is a control box with an anti-spark keyed switch that blocks any charging current from traveling through the charging cables until the switch is thrown. This control facilitates the safe hook-up of the charging clamps while the charger (engine) is running. The charger includes heavy duty cables between the alternator and the anti-spark control box, and additionally out from the control box to insulated clamps that are used to connect to the batteries. The control box additionally includes an ammeter and a voltmeter to indicate the charging current and voltage. The portable charger structured in this manner can be used to charge a non-specific number of batteries in parallel, typically in less than 2-4 hours depending on the size and state of the existing battery charge. The charger may also be used in the process of equalizing a bank of batteries to facilitate a reduction in stratification and sulfation.
