Abstract
A power source is electrically connected with a battery and an electrical load. The power source has an output voltage and provides current for the battery and electrical load. A charging voltage for the battery is determined based on temperature of the battery. An offset voltage is determined based on the provided current to the battery. The output voltage is determined based on the charging and offset voltages.
