Rechargeable battery pack module
First Claim
1. A rechargeable battery pack module adapted to receive a direct current (DC) voltage input from one of a portable computer and an alternating current (AC) adapter so as to be recharged thereby, comprising:
- first and second battery pack terminals;
a battery cell set including a plurality of battery cells connected in series, said battery cell set being connected to said first battery pack terminal, each of said battery cells having a cell voltage;
a DC-to-PC converter having an input side adapted to be connected to said one of the portable computer and the AC adapter, and an output side connected to said second battery pack terminal, said DC-to-DC converter being operable so as to generate charging current from the voltage input;
a safety switch control unit interconnecting said second battery pack terminal and said battery cell set, and operable so as to make electrical connection between said second battery pack terminal and said battery cell set to permit charging of said battery cell set by means of the charging current from said DC-to-DC converter and to permit discharging of said battery cell set via said second battery pack terminal, and so as to break the electrical connection between said second battery back terminal and said battery cell set to stop charging and discharging of said battery cell set;
a first charging protection unit connected to said battery cell set and said safety switch control unit, said first charging protection unit controlling said safety switch control unit to break the electrical connection between said second battery pack terminal and said battery cell set when the cell voltage of any one of said battery cells falls out of a predetermined range; and
a battery status indicating unit for storing manufacturer information corresponding to said battery cell set therein, and connected to said battery cell set and capable of obtaining charging status information therefrom, said battery status indicating unit being adapted to be connected to the portable computer and being capable of providing the manufacturer information and the charging status information to the portable computer to permit display of the manufacturer information and the charging status information on a monitor of the portable computer.
