Disclosed is a battery system that, in a laminated part of a power generating element in a lithium ion rechargeable battery, can properly detect a temperature and the distribution of a temperature change occurring in a positive-negative extending direction and can utilize the detected data in the control of the battery. Also disclosed are a vehicle and a battery-mounting device comprising the battery system. A battery system comprises a lithium ion rechargeable battery. The lithium ion rechargeable battery comprises a power generating element comprising a laminated part, a positive electrode extended part, and a negative electrode extended part. The battery system further comprises a control means and a central temperature detecting means that detects the temperatures of a central laminated part in the laminated part, and at least one of a positive-side temperature detecting means that detects the temperatures of a positive-side laminated part in the laminated part and a negative-side temperature detecting means that detects the temperatures of a negative-side laminated part in the stacked part. The control means controls the lithium ion rechargeable battery using the temperature of the central laminated part, and at least one of the temperature of the positive-side laminated part and the temperature of the negative-side laminated part. |
