Integrated high voltage contactor and service disconnect

1. An integrated contactor/service disconnect assembly, comprising:

a stationary contact;

a movable contact selectively movable relative to said stationary contact; and

a service disconnect unit configured to block said movable contact from contacting said stationary contact;

wherein said service disconnect unit includes a service button and a prong that extends from said service button; and

wherein said prong is movable to a position between said stationary contact and said movable contact.

2. The assembly as recited in claim 1 , wherein said stationary contact is a high voltage pin.

3. The assembly as recited in claim 1 , wherein said movable contact is a busbar carried by a shaft.

4. The assembly as recited in claim 3 , comprising a coil at least partially wrapped around said shaft.

5. The assembly as recited in claim 1 , wherein said service disconnect unit is moveable between a first position in which said stationary contact and said movable contact may contact one another and a second position in which said stationary contact and said movable contact are prevented from contacting one another.

6. The assembly as recited in claim 1 , wherein said service disconnect unit is movable in a first direction and said movable contact is movable in a second, different direction.

7. The assembly as recited in claim 1 , comprising a control unit configured to command movement of said movable contact toward said stationary contact.

8. The assembly as recited in claim 1 , comprising a sensor configured to sense a current through said stationary contact and a fuse configured to interrupt the flow of said current.

9. An energy storage device, comprising:

a contactor; and

a service disconnect unit integrated with said contactor, said service disconnect unit including a prong moveable to a position between two contacts of said contactor to disable high voltage current through said contactor;

wherein said energy storage device is a high voltage battery for an electrified vehicle.

10. The energy storage device as recited in claim 9 , wherein said contactor includes a movable contact and a stationary contact, and said service disconnect unit is moveable between a first position and a second position to prevent contact between said movable contact and said stationary contact.

11. The energy storage device as recited in claim 9 , wherein said service disconnect unit includes a service button positioned relative to an exterior wall of a housing of said contactor and said prong extends inside of said housing.

12. The energy storage device as recited in claim 9 , comprising a control unit configured to energize a coil of said contactor.

13. The energy storage device as recited in claim 12 , wherein said contactor includes a movable contact and a stationary contact, said moveable contact carried by a shaft, said coil wrapped around said shaft, and once energized, said shaft moves to move said movable contact toward said stationary contact.

14. An energy storage device, comprising:

a contactor; and

a service disconnect unit integrated with said contactor, said service disconnect unit including a prong moveable to a position between two contacts of said contactor to disable high voltage current through said contactor;

wherein said contactor and said service disconnect unit are packaged in a single, combined unit.

15. A high voltage battery assembly for an electrified vehicle, comprising:

a first contactor;

a second contactor; at least one of said first contactor and said second contactor including a service disconnect unit comprising:

a service button; and

a prong connected to said service button and moveable between a first position, which is not between contacts of said first contactor or said second contactor, and a second position, which is between said contacts.

16. The high voltage battery assembly as recited in claim 15 , wherein one of said first contactor and said second contactor is a pre-charge contactor.
