Abstract

In one embodiment a multi-mode battery charger for a vehicle is provided. The charger includes a controller. The controller is electrically coupled to a plurality of charging systems. Each charging system is configured to provide a first power from an external power source and to convert the first power into a second power that is suitable for storage on at least one battery on the vehicle. The controller is configured to enable a first charging system of the plurality of charging systems to provide the first power based on a charging priority order in the event two or more of the plurality of charging systems are each determined to provide the first power to the vehicle at the same time.

Claims

1. A multi-mode battery charger for a vehicle comprising:

a controller for being electrically coupled to a plurality of charging systems, each charging system being configured to provide a first power from an external power source and to convert the first power into a second power that is suitable for storage on at least one battery on the vehicle, the controller being configured to enable a first charging system of the plurality of charging systems to provide the first power based on a charging priority order in the event two or more of the plurality of charging systems are each determined to provide the first power to the vehicle at the same time,

wherein the plurality of charging systems comprise an inductive charging system, a conductive charging system, and a direct current (DC) quick charging system, and

wherein the inductive charging system includes a receiver and a power rectifier positioned on the vehicle for providing the second power directly to the battery.

2. The charger of claim 1 wherein the controller is further configured to enable the DC quick charging system to convert the first power into the second power for storage on the at least one battery in the event the controller determines that the DC quick charging system and at least one of the inductive charging system and the conductive charging system provides the first power to the vehicle at the same time.

3. The charger of claim 1 wherein the controller is further configured to enable the conductive charging system to convert the first power into the second power for storage on the at least battery in the event the controller determines that the conductive charging system and the inductive charging system provides the first power to the vehicle at the same time.

4. The charger of claim 1 wherein at least a portion of the conductive charging system includes a converter for converting the first power into the second power and for galvanically isolating the conductive charging system.

5. The charger of claim 1 wherein the controller is further configured to be electrically coupled to a single isolator circuit for each of the plurality of charging systems, and wherein the first power is passed through the single isolator circuit only once for each charging system.

6. The charger of claim 1 wherein the charging priority order is based on a period of time the plurality of charging systems charge the at least one battery with the second power.

7. A multi-mode battery charger for a vehicle comprising:

a controller for being electrically coupled to a plurality of charging systems, each charging system being configured to provide a first power from an external power source and to convert the first power into a second power that is suitable for storage on at least one battery on the vehicle, wherein the controller is further configured to be electrically coupled to a single isolator circuit for each of the plurality of charging systems, and wherein the first power is passed through the single isolator circuit only once for each charging system,

wherein the plurality of charging systems comprise an inductive charging system, a conductive charging system, and a direct current (DC) quick charging system, and

wherein the inductive charging system includes a receiver and a power rectifier positioned on the vehicle for providing the second power directly to the battery.

8. The charger of claim 7 wherein the controller is further configured to enable a first charging system of the plurality of charging systems to provide the first power based on a charging priority order in the event two or more of the plurality of charging systems are each determined to provide the first power to the vehicle at the same time.

9. The charger of claim 8 wherein the charging priority order is based on a speed in which the plurality of charging systems charge that at least one battery with the second power.

10. The charger of claim 8 wherein the plurality of charging systems comprise an inductive charging system, a conductive charging system, and a direct current (DC) quick charging system.

11. The charger of claim 10 wherein the controller is further configured to enable the DC quick charging system to convert the first power into the second power for storage on the at least one battery in the event the controller determines that the DC quick charging system and at least one of the inductive charging system and the conductive charging system provides the first power to the vehicle at the same time.

12. The charger of claim 10 wherein the controller is further configured to enable the conductive charging system to convert the first power into the second power for storage on the at least one battery in the event the controller determines that the conductive charging system and the inductive charging system provides the first power to the vehicle at the same time.

13. The charger of claim 10 wherein at least a portion of the conductive charging system includes a converter for converting the first power into the second power and for galvanically isolating the conductive charging system.

14. The charger of claim 10 wherein the inductive charging system includes a receiver and a power rectifier positioned on the vehicle for providing the second power directly to the battery.

15. A multi-mode battery charger for a vehicle comprising:

a controller for being electrically coupled to a plurality of charging systems, each charging system being configured to provide a first power from an external power source and to convert the first power into a second power that is suitable for storage on at least one battery on the vehicle, the controller being configured to enable a first charging system of the plurality of charging systems to charge the at least one battery with the second power if the first charging system charges the at least one battery at a first period of time that is less than a second period of time for any remaining charging systems of the plurality of charging systems to charge the at least one battery,

wherein the plurality of charging systems comprise an inductive charging system, a conductive charging system, and a direct current (DC) quick charging system, and

wherein the inductive charging system includes a receiver and a power rectifier positioned on the vehicle for providing the second power directly to the battery.

16. The charger of claim 15 wherein the controller is further configured to enable the DC quick charging system to convert the first power into the second power for storage on the at least one battery in the event the controller determines that the DC quick charging system and at least one of the inductive charging system and the conductive charging system provides the first power to the vehicle at the same time.

17. The charger of claim 15 wherein the controller is further configured to enable the conductive charging system to convert the first power into the second power for storage on the at least one battery in the event the controller determines that the conductive charging system and the inductive charging system provides the first power to the vehicle at the same time.
