<p>A battery monitor system (50) is disclosed comprising a microcontroller (52) which monitors voltage inputs from a power adapter (58) and a rechargeable battery. The power adapter (58) includes a voltage source and a current source which outputs two current levels. A thermistor is thermally coupled to the battery (60), and the microcontroller (52) receives voltage inputs from the battery (60) and the thermistor. The microcontroller (52) monitors and processes the voltage inputs to detect a predetermined voltage change corresponding to a change in the battery temperature and/or voltage level which indicates a fully charged battery. The level of the current which is provided to the battery (60) from the current source is under the control of the microcontroller (52), such that the battery (60) is maintained in a fully charged state.</p> |
