Zusammenfassung:	The battery system according to an embodiment includes a first battery and a second battery connected in parallel with the first battery. The first battery includes a lead storage battery. The second battery includes a nonaqueous electrolyte battery. The nonaqueous electrolyte battery includes a positive electrode and a negative electrode. The negative electrode includes a negative-electrode-mixture layer, and the negative-electrode-mixture layer contains lithium titanate. The negative-electrode-mixture layer has a weight per unit area in a range of 15 g/m 2 to 100 g/m 2 and a thickness in a range of 5 µm to 50 µm. The positive electrode contains a positive electrode active material LiMn 2-x M(a) x O 4 . A ratio of a battery capacity of the second battery to a battery capacity of the first battery is in a range of 1/133 to 1/2.
