The microprocessor-control multi-charger for mains and automobile operation is designed for 1-16 cell rechargeable NiCd/NiMH battery packs and 1-5 cell rechargeable Li-ION/Li-Po battery packs. The charging current can be continuously regulated through the entire cell range from 200 mA to 5 A. The charging procedure is monitored using the delta peak for rechargeable NiCd/NiMH battery packs and using the CCCV procedure for rechargeable Li-ION/LiPo battery packs. An external temperature sensor monitors the rechargeable battery pack temperature. NiCd/NiMH or Li-ION/Li-Po is selected manually and the cell count can be detected automatically or selected manually for new unformatted cells. During the charging procedure, a straighforward LCD display indicates the charging current, current voltage, cell count, operating mode and type of the rechargeable battery pack. Furthermore, during the entire charging process, the charged-in capacity is measured and displayed at the touch of a buøÉ |
