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.
Claims18
An automotive vehicle power system comprising:
- a battery charger having an input and output and configured to (i) receive electrical energy via the input when the input is electrically connected with an electrical energy source and (ii) reduce 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.
A plug-in hybrid electric vehicle comprising:
- an electric machine;
- a traction battery electrically connected with the electric machine;
- and
- a battery charger configured to receive electrical energy from an electrical energy source if electrically connected with the electrical energy source and to provide a current to the traction battery at a target value that varies according to a voltage associated with the electrical energy if the voltage associated with the electrical energy falls within a predetermined range of voltages.
A method of charging a vehicle battery comprising:
- determining a voltage on an AC power line electrically connected with an electrical energy source;
- determining whether the voltage falls within a predetermined range of voltages;
- and
- outputting a current to a vehicle traction battery at a target value that varies according to the voltage if the voltage falls within the predetermined range of voltages.
