Abstract
A method for managing an authorized operating range of a battery, the authorized operating range being limited between a minimum level and a maximum level of state of charge of the battery. The method includes estimating a state of health in power of the battery, the state of health in power characterizing capacity of the battery to supply a minimum required power level across an entirety of the operating range; and determining the minimum level of state of charge of the battery in accordance with the estimated state of health in power, the minimum level of state of charge being increased when the state of health in power decreases.

- A method for managing a permissible operating range of a battery, the permissible operating range being bounded between a minimum level and a maximum level of state of charge of the battery, the method comprising;
estimating a state of health in terms of power of the battery, the state of health in terms of power characterizing capacity of the battery to supply a required minimum power level over an entirety of the operating range; determining the minimum level of state of charge of the battery as a function of the estimated state of health in terms of power, the minimum level of state of charge being increased when the state of health in terms of power decreases. - View Dependent Claims (12, 13, 14, 15, 16)
