Abstract
A self-contained apparatus for charging a battery on an electrically powered turf maintenance vehicle. The charger includes an AC to DC converter for accepting a source of AC power and providing a DC voltage, a sensor for measuring the voltage level of the battery, and a controller for determining the voltage of the battery and for changing the charge rate of the battery. The apparatus also includes visual indicators for warning an operator of normal and abnormal charge conditions of the battery, as well as the remaining charge of the battery. Further, the controller uses a plurality of timers for determining the length of charge times and comparing the values of the timers with count values, wherein if the values exceed the count values, then a visual indicator is lit and charging is terminated. The apparatus is mounted in a box-type shell on-board the turf maintenance vehicle.
