Abstract

A power supply control apparatus includes: a control board that is configured to control a voltage of a battery module; and a bus bar module that is configured to electrically connect the control board to the battery module, the control board and the bus bar module are arranged in a stacked manner, and the bus bar module includes a plurality of bus bars that are made to be independent by cutting off junctions connecting the bus bars to each other and a resin member that supports the bas bars in a state where the junctions are exposed.

First claim

The invention claimed is:

1. A method of manufacturing a bus bar module for use in a power supply control apparatus comprising a battery module and a control board, the bus bar module electrically connecting the control board and the battery module, the method comprising:
providing a bus bar assembly comprising a plurality of bus bars, wherein adjacent bus bars of the plurality of bus bars are connected with each other as junctions;
forming a resin member around the bus bar assembly such that at least a portion of each of the plurality of bus bars is embedded within the resin member, the resin member comprising opening portions corresponding to locations of the junctions such that the junctions are exposed in the opening portions; and
cutting the junctions exposed in the opening portions so that adjacent bus bars become electrically independent from each other;
wherein, at each opening portion, at least two bus bars of the plurality of bus bars extend through the opening portion.

2. The method according to claim 1 ,
wherein a longitudinal direction of the opening portions are set to be substantially perpendicular with respect to the extending direction of the embedded bus bars.

3. The method according to claim 2 ,
wherein at least two junctions are arranged in the opening portions along the longitudinal direction of the opening portion.

4. A bus bar module for use in a power supply control apparatus comprising a battery module and a control board, the bus bar module electrically connecting the control board and the battery module, the bus bar module comprising:
a resin member comprising a plurality of opening portions; and
a plurality of bus bars embedded in the resin member;
wherein positions of each of the plurality of opening portions correspond to locations where junctions between adjacent bus bars were cut during manufacturing, the junctions being a part where adjacent bus bars of the plurality of bus bars are connected with each other; and
wherein, at each opening portion, at least two bus bars of the plurality of bus bars extend through the opening portion.

5. The bus bar module according to claim 4 ,
wherein a longitudinal direction of the opening portions are set to be substantially perpendicular with respect to the extending direction of the embedded bus bars.

6. The bus bar module according to claim 5 ,
wherein at least two junctions are arranged in the opening portions along the longitudinal direction of the opening portion.

7. A power supply control apparatus comprising:
a battery module;
a control board; and
a bus bar module electrically connecting the control board and the battery module;
wherein the bus bar module comprises:
a resin member comprising a plurality of opening portions; and
a plurality of bus bars embedded in the resin member;

wherein positions of each of the plurality of opening portions correspond to locations where junctions between adjacent bus bars were cut during manufacturing, the junctions being a part where adjacent bus bars of the plurality of bus bars are connected with each other; and
wherein, at each opening portion, at least two bus bars of the plurality of bus bars extend through the opening portion.

8. The power supply control apparatus according to claim 7 ,
wherein a longitudinal direction of the opening portions are set to be substantially perpendicular with respect to the extending direction of the embedded bus bars.

9. The power supply control apparatus according to claim 8 ,
wherein at least two junctions are arranged in the opening portions along the longitudinal direction of the opening portion.
