METHOD FOR CONTROLLING TRANSFER OF ELECTRIC ENERGY INTO AND OUT AT LEAST ONE RECHARGEABLE ENERGY STORAGE DEVICE.

摘要

Method for controlling transfer of electric energy in to and out at least one rechargeable battery comprising setting a minimum value representing an allowed minimum State of Charge (SoC) of the battery wherein a discharging of the battery is stopped if a value representing the State of Charge of the battery reaches the minimum value representing the minimum State of Charge of the battery, wherein the method comprises varying the minimum value (60) as a function of a value representing the State of Charge of the battery wherein the function is such that the minimum value (60) is decreased if within a predetermined period the value representing the State of Charge exceeds a first predetermined minimum requirement (62) and the minimum value is increased if during a predetermined period the value representing the State of Charge does not exceed a second predetermined minimum requirement (64) wherein the second predetermined minimum requirement corresponds with a lower State of Charge of the battery then the first predetermined minimum requirement.
