Abstract
An automotive vehicle power system includes a battery charger having an input and output. The battery charger receives electrical energy via the input when the input is electrically connected with an electrical energy source. The battery charger also reduces a current provided at the output from a commanded value to a target value that varies according to a voltage at the input if the voltage at the input falls within a predetermined range of voltages.
