Charging apparatus and methods are provided that support multiple charging devices. In an embodiment, a charging apparatus includes a secondary signal generator (SSG) and an output circuit. The SSG receives charging control signals and generates one or more secondary charging control signals. The output circuit outputs the charging control signals to a primary charging device and the one or more secondary charging control signals to one or more secondary charging devices, thereby enabling the use of multiple charging devices in battery applications. In an embodiment, the secondary charging signals are pulse width modulated to control the current output of the secondary charging devices to avoid over-current conditions.
