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 receiv…
