BATTERY SYSTEM AND VEHICLE

摘要

The main purpose of the present invention is to provide a battery system and a vehicle, the safeties of which can be increased. The battery system comprises: a unit cell including a positive electrode layer, a negative electrode layer, and an electrolyte layer disposed between the positive electrode layer and the negative electrode layer; a pressure applying means for changing the internal resistance of the unit cell by applying pressure to the unit cell; a pressure adjusting means capable of adjusting the pressure applied by the pressure applying means; and a control means capable of determining the dangerous extent of the unit cell. In the battery system, the operation of the pressure adjusting means is controlled according to the dangerous extent determined by the control means. In a vehicle mounted with the battery system, the dangerous extent includes a collision and a collision possibility of the vehicle, and the control means can control the operation of the pressure adjusting means according to the presence or absence of the collision and the collision possibility.
