Abstract

A control module which controls battery cells is disclosed which can be used in a charging station, a battery pack and in portable devices such as cellular and cordless phones. The control module comprises a first port configured to connect to a battery cell and an input port configured to connect to an external power supply. Further, the control module comprises a detector module configured to generate a detection signal when the external power supply is connected to the input port, a switching module configured to connect to the input port and the first battery port and to select one of said ports, and a selection module configured to connect to the switching module to receive a signal indicative of an electrical characteristic, and to generating status signals indicative of a charging status. Additionally, the control module has a feedback module associated with the selection module to receive the status signals and to generate a drive signal for controlling input from the external power supply. A processor module is associated with the detection module to receive the detection signal, with the selection module to receive the status signals and with the feedback module to receive the drive signal, and generates control signals to control and terminate charging of the battery cells.
