Electric truck with an electric tailgate
One or more examples provide an electric vehicle or a device for use with an electric vehicle, including an electric vehicle charging system and method. In one example, an electric truck with an electric tailgate is disclosed.
1 . An electric vehicle comprising:
a primary power system, the primary power system including a primary battery pack and an auxiliary battery, where the auxiliary battery pack is at a voltage different than the primary battery pack;
a vehicle control unit in communication with the primary power system, where the vehicle control unit controls operation of the primary power system;
an electric tailgate having a tailgate power system located therein, the tailgate power system including a secondary power system having a secondary battery pack, where the secondary power system is located in a vehicle location different form the primary power system, adjacent to an exterior panel of the electric tailgate, and a comprises a panel battery.
2 . The electric vehicle of claim 1 , where the panel battery is a form fitting battery comprising an outer portion and an inner portion, where the inner portion comprises a fixed shape and the outer portion comprises a flexible shape and is made of a shapeable material that adapts to the shape of a space in the electric tailgate where the battery is located.
3 . The electric vehicle of claim 2 , where the panel battery is flexibly coupled to the exterior panel.
4 . The electric vehicle of claim 2 , where the inner portion comprises a battery or battery pack, and where the outer portion completely surrounds the inner portion.
5 . The electric vehicle of claim 2 , where the panel battery is a shaped flexible battery having a predefined shape that is defined by a shape of the outer portion.
6 . The electric vehicle of claim 2 , the tailgate power system comprising the secondary battery pack, a DC/DC converter, and a secondary auxiliary battery having a voltage different than the secondary battery pack.
7 . The electric vehicle of claim 6 , comprising:
a tailgate cooling system coupled to the tailgate power system; and
a mechanism for coupling the tailgate cooling system to a primary power system battery cooling system of the electric vehicle.
8 . The electric vehicle of claim 7 , comprising:
a power port configured to charge the tailgate power system; and
one or more external power outlets coupled to the secondary auxiliary battery.
9 . An electric vehicle comprising:
a primary power system, the primary power system including a primary battery pack and an auxiliary battery, where the auxiliary battery pack is at a voltage different than the primary battery pack;
a vehicle control unit in communication with the primary power system, where the vehicle control unit controls operation of the primary power system;
an electric tailgate having a tailgate power system located therein, the tailgate power system including a secondary power system including a secondary battery pack, where the secondary power system is located in a vehicle location different from the primary power system, adjacent to an exterior panel of the electric tailgate, and comprises a panel battery that is a flexible battery pack, where upon impact due to an external force the flexible battery pack operates to flex in a predefined manner to mitigate damage to the secondary power system due to the external force.
10 . The electric vehicle of claim 9 , comprising:
a barrier layer flexibly coupled to the flexible battery pack, where the barrier layer is positioned between the exterior panel and the flexible battery pack, where the barrier layer is made of a flexible, puncture proof material.
11 . The electric vehicle of claim 10 , where the barrier layer is movably coupled to the flexible battery pack, and is moveable relative to the flexible battery pack.
12 . The electric vehicle of claim 9 , comprising where the flexible battery pack comprises a flex joint that allows the flexible battery pack to flex at a predefined location upon impact, minimizing damage to batteries located in the flexible battery pack.
13 . The electric vehicle of claim 12 , where flexible battery pack includes a first battery and a second battery, the flex joint being located between the first battery and the second battery, and where the flex joint is at a predefined location within a crash zone of the electric tailgate that causes the battery pack to open up at the predefined location at the flex joint upon impact from an external force.
14 . The electric vehicle of claim 12 , whereupon impact the flex joint causes the flexible battery pack to structurally open up at a predefined location, while maintaining the electrical integrity of the battery pack.
15 . The electric vehicle of claim 14 , the flexible battery pack comprising a first battery, a second battery, and the flex joint located between the first battery and the second battery; and an electrical connection between the first battery and the second battery separate from the flex joint, where the electrical connection comprises an electrical jumper.
16 . The electrical vehicle of claim 12 , where the flex joint is a hinged flex joint.
17 . The electric vehicle of claim 12 , where the flex joint is a sheer joint.
18 . The electric vehicle of claim 12 , comprising:
a barrier layer flexibly coupled to the flexible battery pack, where the barrier layer is positioned between the exterior panel and the flexible battery pack.
19 . The electric vehicle of claim 12 , comprising:
where the flex joint comprises an expansion layer made of an expansion material that operates to mitigate a leak upon impact of an external force to the battery pack.
20 . The electric vehicle of claim 12 , comprising:
one or more tailgate outlets electrically coupled to the secondary battery pack.
