Abstract
A traction battery assembly includes adjacent battery cells supported by a tray and a busbar electrically connecting the adjacent battery cells. The busbar includes a longitudinal midpoint and a pair of bowed sections joined at the midpoint. Each of the bowed sections has an actuate portion in contact with a terminal on one of the cells. The bowed sections provide increased contact with the cells when the cells have different elevations with respect to the tray. A busbar module is also disclosed. The busbar module comprises a housing and a busbar supported within the housing.
Claims15
A traction battery assembly comprising:
- an array of cells including an adjacent pair of cells that each have a planar terminal;
- and
- a plurality of busbar modules each having a housing and a busbar disposed in the housing, a first of the busbar modules including a first housing having a bottom disposed on the pair of cells and end walls extending upward from the bottom, and including a first busbar having a longitudinal midpoint and defining a pair of bowed sections joined at the midpoint, wherein an arcuate portion along each of the bowed sections is in contact with one of the terminals.
A traction battery assembly comprising:
- a tray;
- a pair of adjacent cells supported by the tray and including adjacent terminals with one terminal being part of each cell;
- a housing positioned on the cells opposite the tray and spanning the cells, wherein the housing has a pair of opposing sidewalls cooperating to define an enclosure that receives the terminals, and each of the sidewalls defines an aperture;
- and
- a busbar received within the enclosure and extending in a same direction as the sidewalls, the busbar having a longitudinal midpoint and a pair of bowed sections joined at the midpoint, wherein each of the bowed sections is in contact with one of the terminals when the terminals are at different elevations relative to the tray to provide increased contact between the busbar and terminals, and the busbar further has a pair of projections each extending substantially perpendicular from the longitudinal midpoint and received in one of the apertures.
A traction battery comprising:
- adjacent cells each including a terminal;
- a busbar module spanning the cells and including opposing sidewalls defining slots and an enclosure that receives the terminals;
- and
- a busbar having a longitudinal midpoint and defining a pair of rockers connected at the midpoint and projections each extending perpendicularly from the midpoint and into one of the slots, each of the rockers having a curved portion in contact with one of the terminals.
