Apparatus for charging multiple batteries

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 battery charging module is connected directly to the power supply output port, and the electrical input ports of additional battery charging module modules are connected directly to the previous battery charging module electrical output port. In this manner a train of battery charging module modules is formed, headed by a single power supply.
