A battery assembly utilizing a compact and robust bus bar configuration is provided. The batteries within the assembly are divided into groups with each group formed from at least two rows of batteries. The batteries within each battery group are connected in parallel and the groups are connected in series. The batteries are interconnected using a plurality of non-overlapping bus bars configured in an alternating pattern with the plurality of battery groups, where each of the bus bars includes multiple interconnect mounting platforms. The interconnect mounting platforms simplify coupling multiple rows of batteries to each bus bar while minimizing bus bar current density variations and insuring that individual interconnect resistance remains relatively low and at about the same level per battery.

Battery pack bus bar assembly with shaped interconnect mounting platforms

A battery assembly utilizing a compact and robust bus bar configuration is provided. The batteries within the assembly are divided into groups, for example where each group is formed from two rows of batteries. The batteries within each battery group are connected in parallel and the groups are connected in series. The batteries are interconnected using a plurality of non-overlapping bus bars configured in an alternating pattern with the plurality of battery groups, where each of the bus bars includes multiple interconnect mounting platforms. The interconnect mounting platforms simplify coupling multiple rows of batteries to each bus bar while minimizing bus bar current density variations and insuring that individual interconnect resistance remains relatively low and at about the same level per battery.

Battery pack bus bar assembly with enlarged interconnect mounting platforms

A battery assembly utilizing a compact and robust bus bar configuration is provided. The batteries within the assembly are divided into groups, where the batteries within each battery group are connected in parallel and the groups are connected in series. The batteries are interconnected using a repetitive sequence of non-overlapping, alternating polarity bus bars. The bus bars, which are integrated into a battery assembly upper tray member, are devoid of contact fingers and positioned such that there is a single bus bar located adjacent to either side of each battery group.
