Method for operating energy storage device e.g. battery in vehicle, involves reducing stress applied to storage device temporarily, when predicted residual lifetime of storage device is less than predetermined residual lifetime
Method for operating energy storage device e.g. battery in vehicle, involves reducing stress applied to storage device temporarily, when predicted residual lifetime of storage device is less than predetermined residual lifetime
The method involves determining (102) a parameter of energy storage device in vehicle and predicting (103) residual lifetime of the energy storage device based on the determined parameter. Stress applied to the energy storage device is temporarily reduced, when detecting (104) that the predicted residual lifetime of the storage device is less than a predetermined residual lifetime. The parameter is selected from expected lifetime, throughput or state of charge. Independent claims are included for the following: (1) device for operating energy storage in vehicle; and (2) vehicle.
