Stackable battery bussing system
View Patent ↗A stackable electrical-energy bussing system, for energy storage battery cells constructed according to the present invention includes a battery cell case having electrically conductive terminals that fit together with the terminals of a similar battery cell in order to enable multiple battery cells to be interconnected physically and electrically by stacking them atop each other. A Stackbatt bussing system housing contains the electricity-producing elements for each cell, connected from each opposing side. Preferably, the battery cell includes at least two such male terminals in spaced-apart relationship on the top side of the cell case, and at least two such female bus tubes that mate and receive with a spaced-apart relationship on both sides of the Stackbatt bussing system. Preferably, a multi-cell battery bussing system constructed to the invention includes multiple battery cells as described above, stacked when desired to achieve desired battery voltage for series and or parallel configurations.
1. An electrical bus bar assembly that is configured to receive pole terminals of at least one battery cell, said electrical bus bar assembly comprising:
a housing that defines a first side and a second side, said housing further defining first and second openings on said first side of said housing and also further defining first and second openings on said second side of said housing;
a first bus tube that defines one end, said first bus tube also defining a second end that is located oppositely on said first bus tube from said one end, said one end of said first bus tube being aligned with said first opening on said first side of said housing, said second end of said first bus tube being aligned with said first opening on the second side of said housing, said first bus tube being capable of receiving a pole terminal of a first battery cell in one end of said first bus tube and receiving a pole terminal of a second battery cell in the second end of said first bus tube;
a bus bar having upper and lower parts that are located within said housing, the upper part of said bus bar being electrically connected to said first bus tube;
a first electrical connector that is secured to the upper part of said bus bar;
a second electrical connector that is secured to the lower part of said bus bar, said second electrical connector being complementarily engageable with said first electrical connector; and
a second bus tube that defines one end, said second bus tube also defining a second end that is located oppositely on said second bus tube from said one end, said one end of said second bus tube being aligned with the second opening on said first side of said housing, said second end of said second bus tube being aligned with the second opening on the second side of said housing, said second bus tube being capable of receiving a pole terminal of a first battery cell in one end of said first bus tube and receiving a pole terminal of a second battery cell in the second end of said first bus tube.

5. The electrical bus bar assembly of claim 1 further comprising at least one fastener for securing said first housing part together with said second housing part.
6. An electrical bus bar assembly that is configured to receive pole connectors of at least one battery cell, said electrical bus bar assembly comprising:
a first housing part;
a second housing part that cooperates with said first housing part to define first and second openings for respectively receiving a pole connector of at least one battery cell;
a first bus tube is aligned with said opening defined by said first and second housing parts, said first bus tube having an inner diameter that is capable of receiving a pole connector that is inserted through the first opening defined by first and second housing parts;
a bus bar having upper and lower parts, said bus bar being located between said first housing and said second housing, the upper part of said bus bar being electrically connected to said first bus tube;
a first electrical connector that is secured to the upper part of said bus bar, said first electrical connector defining an electrical receiver;
a second electrical connector that is secured to the lower part of said bus bar, said second electrical connector defining an electrical plug of a type that is engageable with a receiver of the type defined by said first electrical connector; and
a second bus tube that is aligned with said second opening defined by said first and second housing parts, said second bus tube having an inner diameter that is capable of receiving a pole connector that is inserted through the second opening defined by first and second housing parts.
7. The electrical bus bar assembly of claim 6 further comprising an insulation shroud that is located between a portion of the upper part of said bus bar and a portion of the lower part of said bus bar.
