    摘要： To provide a battery pack capable of suppressing heat generation due to current flowing through a bus bar and thus suppressing cell deterioration, and improving battery performance by weight reduction. A battery pack 10 includes first to fourth cells 1 to 4 stacked together, each cell including a positive electrode external terminal 12 and a negative electrode external terminal 13 having higher conductivity, and a bus bar 6 that electrically connects the positive electrode external terminal 12 of the second cell 2 and the negative electrode external terminal 13 of the third cell 3, the second and third cells 2 and 3 being disposed side by side next to each other. The bus bar 6 includes a first conductive part 6a connected to the positive electrode external terminal 12 of the second cell 2, a second conductive part 6b connected to the negative electrode external terminal 13 of the third cell 3 and having higher conductivity and higher specific gravity, and a connecting part 6c that connects the first conductive part 6a and the second conductive part 6b. The connecting part 6c is disposed in a first region facing the second cell 2 or in a second region facing the third cell 3.

    摘要： The disclosure provides a busbar assembly (H) and a cell module. The busbar assembly (H) includes a busbar bracket (110), a conductive member (200), and a tab lead-out slit (310). The busbar bracket (110) has a first side (A) and a second side (B) facing away from each other. The conductive member (200) is arranged on the busbar bracket (110). The tab lead-out slit (310) extends from the first side (A) to the second side (B) and passes through the busbar bracket (110). The tab lead-out slit (310) has two opposite lead-out walls (301, 302), and at least one of the lead-out walls (301, 302) is formed on the conductive member (200).

    摘要： The disclosure relates to a battery assembly (10) comprising at least one electric battery cell (12) and at least one coolant channel (38, 40) being configured to guide a coolant. The at least one electric battery cell (12) comprises at least a first electrode (24) being electrically connected to a first cell terminal (20) and a second electrode (26) being electrically connected to a second cell terminal (22). Moreover, each of the first cell terminal (20) and the second cell terminal (22) comprises an electric connection surface (28, 30) for electrically connecting the respective first cell terminal (20) or second cell terminal (22) and at least one of the first cell terminal (20) and the second cell terminal (22) comprises a thermal connection surface (34, 36) being separate from the respective electric connection surface (28, 30). The coolant channel (38, 40) is thermally coupled to the thermal connection surface (34, 36). Additionally, an electric battery cell (12) for such a battery assembly (10) is presented. Moreover, a vehicle comprising a battery assembly (10) is explained.
