Abstract: A multiple cell battery charger with a parallel topography is disclosed which requires fewer active components than known battery chargers and protects the battery cells from overcharge and discharge. The charger that includes a regulator for providing a regulated source of direct current (DC) voltage to the battery cells to be charged. Each battery cell is connected in series with a switching device, such as a field effect transistor (FET) and optionally a current sensing device. In a charging mode, the serially connected FET conducts, thus enabling the battery cell to be charged. Battery voltage is sensed by a microprocessor. When the microprocessor senses that the battery cell is fully charged, the FET is turned off, thus disconnecting the battery cell from the circuit. Since the battery cell is disconnected from the circuit, no additional active devices are required to protect the battery cell from discharge.
