High-voltage battery with integrated cell connector
Provided is a high-voltage battery with an integrated connector. The high-voltage battery includes cells, support members, a housing, the integrated connector and a BMS. A lower connection member is provided on one side of each support member and has protrusions made of electrical conductors. The protrusions come into contact with corresponding electrodes of the cells. A cell assembly formed by the arrangement of the cells and the supports is inserted into the housing. The integrated connector is connected to the lower connection members of the support members so as to mechanically and electrically connect the cells to each other.
1. A high-voltage battery, comprising:
a plurality of cells, each cell having a plate shape and electrodes protruding upwards;
a plurality of support members each interposed between two adjacent cells to support the cells, each of the support members being made of an electrical insulation material;
a plurality of lower connection members each provided on top of each of the support members, the lower connection member having protrusions made of an electrical conduction material, the protrusions protruding upwards with respect to the cells and in contact with the electrodes of the cells, wherein the cells and the support members having the lower connection members stack alternately and form a cell assembly;
a housing into which the cell assembly is inserted;
an integrated connector installed on the lower connection members of the support members so as to mechanically and electrically connect the cells to each other, wherein the integrated connector includes: a connection block made of an electrical insulation material and having a planar shape; a plurality of upper connection members formed in the connection block and made of an electrical conduction material, each of the upper connection members being positioned at and electrically in contact with each corresponding lower connection member; and a signal wire made of an electrical conduction material and connected to each of the upper connection members; and
a BMS (battery management system) electrically connected to the integrated connector through the electrical wire, the BMS electrically controlling the cells.
2. The high-voltage battery as set forth in claim 1 , wherein each of the protrusions of the lower connection members has a screw shape, and
the integrated connector further includes through holes formed in the upper connection members and the protrusions of the lower connection members being inserted into the through holes.
