Abstract: A system generally comprising a charger with an integrated battery is provided that may be associated with a generator starter. The system is configured to maintain battery charge with the charger that monitors battery temperature before initiating a boost charge. Battery charge is thereafter maintained with the charger supplying a float or eco-float current to the battery, which maximizes system life.

Abstract: There is disclosed an enclosure and cooling system for electronic equipment that provides forced-air cooling of multiple compartmentalized electronics assemblies while simultaneously isolating the electronics assemblies from the ambient environment, keeping the electronics assemblies free from contamination due to harmful dust, dirt, water, corrosives, and other airborne foreign matter. Embodiments include an air-conduction cooled environmentally-sealed electronics enclosure having at least first and second environmentally-sealed electronics compartments, each containing a respective electronic assembly. A common-air cooling channel containing a fin core is disposed between the first and the second electronics compartments, such that ambient air drawn from an air intake, through the common channel, and out an air exhaust removes heat generated by the electronic assemblies within the sealed compartments to an exterior of the enclosure. Other embodiments are disclosed.

Abstract: The disclosure provides embodiments of a self-contained automatic battery charging system having a power printed circuit board (PCB) that enables inputting an alternating current (AC) power flow to the automatic battery charging system. A first switchmode converter converts an AC input power to a direct current (DC) power, thereby providing an active power factor correction. The first switchmode converter comprises an isolation transformer, which provides an electrical isolation between a primary circuitry and a secondary circuitry of the automatic battery charging system. A second switch mode converter regulates a system output voltage and limits a system output current to an electrical load. A DC output is connected to a battery, another electrical storage device, and/or a parallel-connected DC load to be powered.

The system may implement a battery-life-extension charging regime.
