Abstract

A busbar module includes a plurality of busbars that are connected to two or more electrode terminals in an electrode terminal group arranged in a row in a battery module including a plurality of battery cells, a housing case that has insulation property and includes a plurality of housing spaces that house the respective busbars, and a plurality of voltage detection conductors that are connected to the respective busbars. The voltage detection conductors are formed integrally with the housing case.

First claim

What is claimed is:

1. A busbar module, comprising:
a plurality of busbars that are connected to two or more electrode terminals in an electrode terminal group arranged in a row in a battery module including a plurality of battery cells;
a housing case that has insulation property and includes a plurality of housing spaces that house the respective busbars; and
a plurality of voltage detection conductors that are electrically connected to the respective busbars, wherein
the voltage detection conductors are formed integrally with the housing case, and
the voltage detection conductors are buried inside the housing case.

2. The busbar module according to claim 1 , wherein
the voltage detection conductors are printed circuit members attached to a surface of the housing case.

3. The busbar module according to claim 1 , wherein
the housing case includes frame bodies forming the housing spaces and covers that plug the respective frame bodies, the frame bodies and the covers being paired with each other,
the frame bodies and the covers are coupled with a hinge, and
the voltage detection conductors are formed from the covers to the frame bodies via at least the hinge.

4. The busbar module according to claim 2 , wherein
the housing case includes frame bodies forming the housing spaces and covers that plug the respective frame bodies, the frame bodies and the covers being paired with each other,
the frame bodies and the covers are coupled with a hinge, and
the voltage detection conductors are formed from the covers to the frame bodies via at least the hinge.

5. The busbar module according to claim 1 , wherein
each of bottom portions forming the respective housing spaces has a connection hole, and
each of the voltage detection conductors is in contact with the corresponding busbar, while one end of the voltage detection conductor is exposed in the connection hole.

6. The busbar module according to claim 2 , wherein
each of bottom portions forming the respective housing spaces has a connection hole, and
each of the voltage detection conductors is in contact with the corresponding busbar, while one end of the voltage detection conductor is exposed in the connection hole.

7. The busbar module according to claim 3 , wherein
each of bottom portions forming the respective housing spaces has a connection hole, and
each of the voltage detection conductors is in contact with the corresponding busbar, while one end of the voltage detection conductor is exposed in the connection hole.

8. The busbar module according to claim 5 , wherein
each of the busbars has a connection projection that is to be inserted in the connection hole, and
each of the voltage detection conductors is in contact with the connection projection, while one end of the voltage detection conductor is exposed in the connection hole.

9. The busbar module according to claim 6 , wherein
each of the busbars has a connection projection that is to be inserted in the connection hole, and
each of the voltage detection conductors is in contact with the connection projection, while one end of the voltage detection conductor is exposed in the connection hole.

10. The busbar module according to claim 7 , wherein
each of the busbars has a connection projection that is to be inserted in the connection hole, and
each of the voltage detection conductors is in contact with the connection projection, while one end of the voltage detection conductor is exposed in the connection hole.
