Abstract
In a remote battery charging system comprising a charging circuit there is always a voltage loss due to inherent resistances in the system from such things as connectors and conductors. These resistances create voltages losses in the system such that charging time are increased substantially. The present invention compensates for voltage losses on the system by generating a dynamic adjustment voltage over the charging period. A voltage translator circuit is used to measure charging circuit output voltage and current over a plurality of incremental time periods during the charging period an calculate a signal proportional to changes in output voltage and current over the incremental time period. The signal is then applied to the charging circuit to offset any voltage losses.
