Abstract
Metal cell tanks including secondary cells respectively are connected to one another by connection members. For example, a connection member has: an insulation portion interposed between adjacent cell tanks for keeping the cell tanks electrically insulated from each other; an one-end holding portion extending from one end of the insulation portion for holding one end portion of one of the adjacent cell tanks; and an opposite-end holding portion extending from the other end of the insulation portion for holding the other end portion of the other of the adjacent cell tanks.
Claims6
A connection member for connecting a plurality of metal cell tanks, comprising:
- each metal cell tank having a first end portion, a second end portion and plurality secondary cells;
- the connection member having a shape and configuration that holds the secondary cells which provide an electric source for driving a vehicle,
- wherein:
- an insulation portion is interposed between adjacent metal cell tanks for keeping the adjacent metal cell tanks electrically insulated from each other;
- a first-end holding portion extends from a first end of said insulation portion and holds the first end portion of one of the adjacent metal cell tanks;
- a second-end holding portion extends from a second end of said insulation portion and holds the second end portion of the other of the adjacent metal cell tanks;
- and
- said first-end holding portion and said second-end holding portion are arranged back to back on said insulating portion and extend in opposite directions.
