Estimating the term…
The present invention is a method and a system for the energy management of an energy storage of an electrical system. The electrical system comprises at least one element (EMO) which moves under the action of swell, a means for driving the mobile means, and an energy storage. The energy storage means includes at least one supercapacitor. According to the invention, the energy management of the supercapacitor is controlled by determining ageing of the at least one supercapacitor beforehand used an ageing model of the at least one supercapacitor and a prediction of its future demand based on an estimate of future swell (HOU). The invention also relates to a wave energy system and a heave compensator having such an energy management system.

A method for energy management of an energy storage of an electrical system, the electrical system including at least one mobile element, at least one means for electrically driving the at least one mobile element, and at least one electrical energy storage for supplying or recovering electrical energy to or from the at least one means for electrically driving, the at least one mobile element being subjected to swell, and the at least one electrical storage comprising at least one supercapacitor, an ageing model of the supercapacitor which links the state of ageing of the at least one supercapacitor with demand on the at least one supercapacitor, comprising:
A system for the energy management of an energy storage of an electrical system, the electrical system including at least one mobile element, at least one means for electrically driving the at least one mobile element, and at least one electrical energy storage for supplying or recovering electrical energy to or from the at least one means for electrically driving, the at least one mobile element being subjected to swell, and the electrical storage comprising at least one supercapacitor, wherein the energy management system comprises means for determining a state of future swell, means for determining a future demand on the at least one supercapacitor by the at least one means for driving, means for determining ageing of the at least one supercapacitor by use of an ageing model of the at least one supercapacitor and of the demand on the at least one supercapacitor, and means for controlling the energy management of the at least one supercapacitor based on of the ageing of the at least one supercapacitor, the ageing model of the at least one supercapacitor linking ageing of the at least one supercapacitor with the demand.
