Abstract:
To suppress high rate deterioration at an appropriate timing in a secondary battery system installed in a vehicle.SOLUTION: A ECU 100 acquires the vibration intensity of an assembled battery 110 set in advance by using position information on a vehicle 10 with respect to each point of a planned travel route of the vehicle 10 and calculates a resistance value R indicating the difficulty of high rate degradation by using a deterioration index value ΣD and the vibration intensity G, and starts executing high rate deterioration suppression control before the vehicle 10 reaches a point where the resistance value R is less than a reference value Rc in the planned travel route of the vehicle 10.SELECTED DRAWING: Figure 9
