Abstract: A battery module includes: a plurality of batteries stacked together; and a busbar that electrically connects the plurality of batteries with each other. The busbar has: a main body that extends along axis X along which the batteries are stacked together; and a plurality of connectors that protrude from the main body along an axis that intersects with the axis along which the batteries are stacked together, and are electrically connected with terminals of the batteries, respectively. The plurality of batteries are divided into a plurality of battery units. Each of the plurality of battery units includes at least two of the plurality of batteries. The busbar connects the at least two of the plurality of batteries of each of the battery units with each other in parallel. The busbar connects the battery units with each other in series.

Abstract: A battery module includes a plurality of batteries stacked together, and a busbar. Each of the plurality of batteries includes a battery-side first structure and a battery-side second structure that regulate the connection of the battery and the busbar. The busbar has a busbar-side first structure and a busbar-side second structure that regulate the connection of the busbar and each of the batteries. If the battery-side first structures of the plurality of batteries are combined with the busbar-side first structure, and the battery-side second structures of the plurality of batteries are combined with the busbar-side second structure, each of the batteries is connected with the busbar. Alternatively, if the battery-side first structure of any one of the batteries is combined with the busbar-side second structure, the one of the batteries or another one of the batteries is not connected with the busbar.
