Abstract:
A busbar connector (60) for making one or more electrical connections within or to a battery module (M) of a battery pack, the battery module (M) comprising one or more battery cells, wherein the busbar connector (60) comprises: a base portion (160) for forming an electrical connection to one or more of the battery cells within the module; and at least one connector portion (180, 190) for forming an electrical connection from the base portion (160) to one or more other components of the module or the battery pack; wherein at least one or more of the following (i) to (iv) is satisfied: (i) the at least one connector portion (180, 190) has a non-uniform transverse cross-sectional area passing therealong, or (ii) the at least one connector portion (180, 190) has a lateral width which varies passing therealong, or (iii) the base portion (160) has a longitudinal length, the base portion (160) and the at least one connector portion (180, 190) are united or joined via an attachment portion, and the attachment portion has a length dimension, in the same direction as the longitudinal length of the base portion (160), which is greater than the lateral width of the at least one connector portion (180, 190) at locations therealong spaced or distal from the attachment portion, or (iv) the base portion (160) has a longitudinal length, and the at least one connector portion (180, 190) extends transversely from a lateral side of the base portion (160), and further extends in a general length direction (L) thereof which lies at an angle relative to the longitudinal length direction of the base portion (160), wherein the said angle lies in the range of from greater than 0 or 2 or 5 or 10 or 15 or 20 or 25° up to 30 or 40 or 50 or 60 or 70 or 80 or 90° relative to the longitudinal length direction of the base portion (160).
