Abstract
A modular battery charging system is provided in two main embodiments. In a first embodiment, the modular battery charging system includes a power supply, an elongated track, a connector, and at least one battery charging module. The power supply converts an outlet alternating current voltage supply to a stepped-down direct current voltage supply of an amount equal to or less than about 30 volts. The elongated track includes a number of conductive strips, interfitting with each other. The battery charging module includes a housing, a charging unit supported within the housing, a number of electrical connection components to contact the track strips and to extend to the charging unit, and a battery device receiving port to receive the particular battery device in need of charging. In a second embodiment, the modular battery charging system includes a power supply and one or more battery charging module modules. The battery charging module modules include a housing having an electrical input port and an electrical output port, a charging unit positioned and supported within the housing, and a number of electrical connection components. During use, the electrical input port of a first…
