Abstract

This disclosure details electrified vehicles that are equipped with removable generators for increasing the electric range of the vehicles. An exemplary electrified vehicle includes a cargo space, such as a truck bed, and a generator removably positioned within the cargo space. The generator is adapted to selectively supply power for either charging a battery pack of the electrified vehicle or for propelling one or more vehicle drive wheels. In some embodiments, the generator is shaped like, and therefore disguised as, a toolbox.

First claim

What is claimed is:

1. An electrified vehicle, comprising:
a drive wheel;
a battery pack;
a cargo space; and
a generator removably positioned within the cargo space and adapted to selectively output power for either charging the battery pack or propelling the drive wheel,
wherein the generator is box shaped,
wherein the generator includes locating studs received within openings of the cargo space.

2. The electrified vehicle as recited in claim 1 , wherein the generator is interchangeable with a second generator that includes a different power capacity compared to the generator.

3. The electrified vehicle as recited in claim 1 , wherein the generator is connected in series relative to the battery pack.

4. The electrified vehicle as recited in claim 1 , comprising a control system configured to control the power outputted by each of the battery pack and the generator during a drive cycle.

5. An electrified vehicle, comprising:
a drive wheel;
a battery pack;
a cargo space;
a generator removably positioned within the cargo space and adapted to selectively output power for either charging the battery pack or propelling the drive wheel,
wherein the generator is box shaped;
a control system configured to control the power outputted by each of the battery pack and the generator during a drive cycle; and
a human machine interface in communication with the control system and configured to receive an operating mode input for controlling the generator during the drive cycle.

6. The electrified vehicle as recited in claim 5 , wherein the cargo space is located onboard the electrified vehicle.

7. The electrified vehicle as recited in claim 5 , wherein an enclosure of the generator includes a first mounting flange on a first side of the enclosure and a second mounting flange on a second, opposite side of the enclosure, and each of the first and second mounting flanges includes a locating stud for locating the generator relative to the cargo space.

8. An electrified vehicle, comprising:
a passenger cabin;
a truck bed rearward of the passenger cabin;
a generator removably mounted within the truck bed and including an outer enclosure disguised as a saddle-style truck bed toolbox; and
a connection system including a first connector recessed into a floor of the truck bed and a second connector protruding from a bottom wall of the generator.

9. The electrified vehicle as recited in claim 5 , wherein the electrified vehicle is a pickup truck, and the cargo space is established by a truck bed of the pickup truck.

10. The electrified vehicle as recited in claim 5 , wherein at least a portion of a bottom wall of the generator is spaced a distance above a floor of the cargo space.

11. The electrified vehicle as recited in claim 5 , wherein the generator includes an enclosure that houses an engine and a fuel tank.

12. The electrified vehicle as recited in claim 11 , wherein the enclosure further houses an exhaust system and electronics of the generator.

13. The electrified vehicle as recited in claim 5 , comprising a connection system for electrically connecting the generator to a voltage bus of the electrified vehicle.

14. The electrified vehicle as recited in claim 13 , wherein the connection system includes a vehicle-side connector and a generator-side connector.

15. The electrified vehicle as recited in claim 14 , wherein the vehicle-side connector is recessed into a floor of the cargo space and the generator-side connector protrudes from a bottom wall of the generator.

16. The electrified vehicle as recited in claim 14 , wherein the vehicle-side connector is a female connector and the battery-side connector is a male connector.
