Abstract
The invention is a method of using a system for storing electrical power which minimizes aging of the system. An optimal profile of use is defined to minimize the aging of the system. An initial profile of use is chosen. A dynamic model of aging of the system is defined which modes the losses of electrical capacity and/or power of the system as a function of time. Next, by use of the dynamic model of aging, an aging indicator is determined for the system after this profile has been applied to the system. Last, the profile of use is modified and the step of calculating the indicator is reiterated until a minimal aging indicator is obtained. The optimal profile is then applied to the system for storing electrical power.

11. A method of using a system for storing electrical power, which include a positive electrode, a negative electrode and an electrolyte,
In which an optimal profile of use for the system allowing the aging of the system to be minimized is defined by the steps comprising: -
i) choosing an initial profile of use; ii) defining a dynamic model of aging of the system which models losses of electrical capacity and/or power of the system, the model being a dynamic model modeling the losses as a function of time and which accounts for an initial aging state of the system before the initial profile of use has been applied; iii) determining an aging indicator for the system after the initial profile of use has been applied to the system, by use of the dynamic model of aging; and iv) modifying the initial profile of use and reiterating step iii) until a minimal aging indicator is obtained; and applying the optimal profile to the system. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 23, 24, 25, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51)
