Abstract

An automotive vehicle includes a charge port integrated with the vehicle. The charge port includes electrical contacts configured to receive electrical power from an electric grid, and a fault interrupt circuit electrically connected with the electrical contacts.

Claims

1. An automotive vehicle comprising:

a battery charger disposed within the vehicle; and

a charge port integrated with the vehicle and including (i) electrical contacts configured to receive electrical power from an electric grid and (ii) a fault interrupt circuit electrically connected with the electrical contacts and the battery charger.

2. The vehicle of claim 1 further comprising a power storage unit electrically connected with the battery charger.

3. The vehicle of claim 2 wherein the power storage unit is a traction battery.

4. An automotive vehicle comprising:

a charge port integrated with the vehicle and including (i) electrical contacts configured to receive electrical power from an electric grid and (ii) a fault interrupt circuit electrically connected with the electrical contacts.

5. The vehicle of claim 4 further comprising a power converter, wherein the fault interrupt circuit is electrically connected with the power converter.

6. The vehicle of claim 5 wherein the power converter is a battery charger.

7. The vehicle of claim 5 further comprising a power storage unit electrically connected with the power converter.

8. The vehicle of claim 4 further comprising a power converter and another fault interrupt circuit, wherein the another fault interrupt circuit is electrically connected with the charge port and the power converter.

9. The vehicle of claim 8 wherein the power converter is an inverter.

10. An automotive power system comprising:

a power storage unit;

a power converter electrically connected with the power storage unit; and

a charge port integrated with the vehicle and including electrical contacts configured to receive electrical power from a remote power source, and a fault interrupt circuit electrically connected with the power converter and the electrical contacts.

11. The system of claim 10 further comprising another fault interrupt circuit electrically connected with the power converter and charge port.

12. The system of claim 10 wherein the power converter is a battery charger.

13. The system of claim 10 wherein the power storage unit is a battery.
