a plurality of voltage modules, each voltage module having a terminal; and

a connection device having a conductive and nonconductive portions;

wherein the conductive portion contacts the terminals of at least two voltage modules when disposed in a first position and the nonconductive portion contacts at least one terminal of the at least two voltage modules when disposed in a second position.

2. The battery assembly of claim 1 wherein the conductive and nonconductive portions are coaxially disposed.

3. The battery assembly of claim 2 wherein conductive portion has a generally cylindrical configuration and is disposed around a nonconductive core.

4. The battery assembly of claim 2 wherein the connection device further comprises a first end coupled to an actuator adapted to move the connection device between the first and second positions in response to an actuation signal.

5. The battery assembly of claim 1 wherein the conductive portion is disposed adjacent to a plurality of nonconductive portions.

6. The battery assembly of claim 1 wherein the connection device further comprises a first and second ends, the first end having a tool engagement feature and the second end having a retention feature.

7. The battery assembly of claim 1 wherein the battery assembly further comprises a housing for receiving the plurality of voltage modules, the housing including first and second apertures, and wherein the connection device further comprises first and second ends, wherein the first and second ends are disposed proximate the first and second apertures, respectively, when the connection device is in the first position.

8. The battery assembly of claim 1 further comprising a housing having a compartment that receives the plurality of voltage modules and wherein the connection device covers the compartment.

9. The battery assembly of claim 8 wherein the conductive portion is disposed proximate a surface of the nonconductive portion that faces the compartment.

10. The battery assembly of claim 1 wherein the conductive portion has a non-planar configuration for providing a biasing force against the terminals of the at least two voltage modules when disposed in the first position.

11. A battery assembly for a vehicle, comprising:

a first set of voltage modules connected in series;

a second set of voltage modules connected in series;

a housing for receiving the first and second sets of voltage modules, the housing having an end surface; and

a connection device configured to engage the end surface, the connection device having a conductive portion disposed proximate a nonconductive interior surface;

wherein the first and second sets of voltage modules are connected in series when the conductive portion contacts a member of the first set and a member of the second set.

12. The battery assembly of claim 11 wherein the connection device is spaced apart from the end surface when the first set of voltage modules is not connected in series with the second set of voltage modules.

13. The battery assembly of claim 11 wherein the connection device is configured to move along the end surface between a first position in which the conductive portion connects the first and second sets of voltage modules in series and a second position in which the conductive portion is spaced apart from at least one of the first and second sets of voltage modules.

14. The battery assembly of claim 11 wherein a section of the conductive portion protrudes from the nonconductive interior surface.

15. The battery assembly of claim 11 wherein the conductive portion has a corrugated configuration for providing a biasing force against members of the first and second sets of voltage modules when the conductive portion contacts a member of the first set and a member of the second set.

16. A high voltage battery assembly for a vehicle, comprising:

a housing;

first and second sets of voltage modules at least partially disposed in the housing, the members of the first set being connected in series and the members of the second set being connected in series; and

a connection device having coaxial conductive and nonconductive portions at least partially disposed in the housing;

wherein the connection device moves linearly between a first position in which the conductive portion connects the first and second sets of voltage modules in series and a second position in which the conductive portion does not connect the first and second sets of voltage modules in series.

17. The high voltage battery assembly of claim 16 wherein a member of the first set includes a first terminal having a first terminal aperture and a member of the second set includes a second terminal having a second terminal aperture, wherein the connection device is moveably disposed in the first and second terminal apertures.
