Abstract:
1. A method for charging a power storage element of an autonomous system comprising electronic components from a generator, with limiting, according to the temperature, of the power supplied to the storage element to a charging setpoint power, method comprising estimating the time period during which the power resource available to the generator is, up to a preset moment, greater than a preset threshold value, estimating the temperature progression up to said moment, estimating the progression of a maximum acceptable power up to said moment, according to the temperature progression and to data representative of the reliability of the system according to the temperature, determining the energy required to charge the storage element, calculating, according to the energy required and to said time period, of a theoretical mean power spread over said time period to come, to be delivered to the storage element to charge the latter completely, estimating from the maximum acceptable power of a maximum energy during the time period to come able to be delivered by the generator, determining a charging setpoint power according to the comparison between the required energy and the maximum energy and to the comparison between the mean power and the maximum charging power.
