According to one embodiment, there is provided a battery module comprising five to seven nonaqueous electrolyte batteries which are electrically connected in series, comprising a container (2), a nonaqueous electrolyte provided in the container (2), a positive electrode (3) and a negative electrode (4). The positive electrode (3) includes a positive electrode current collector (3a) containing Al, and a positive electrode active material containing layer (3b). The negative electrode (4) includes a negative electrode current collector (4a) containing Al, and a negative electrode active material containing layer (4b). The negative electrode active material containing layer (4b) includes titanium-containing oxide particles having an average secondary particle size of more than 5 µm. The nonaqueous electrolyte battery satisfies a formula (1) of Lp < Ln. |
