Abstract
A universal battery pack which includes an integral power converter and a dynamically adjustable output voltage. The default output voltage is set by an optional resistor connection, which shifts the voltage-dividing ratio into the error amplifier. In a multiple-battery configuration, the output voltages of the separate battery modules are preferably set to slightly different values. Thus the battery module with the highest output voltage setting will be completely exhausted first. This results in automatic battery switchover, without requiring any control algorithm or logic for execution of the switchover.
