Method and device for optimized recharging of an electric battery
First Claim
1. A method for the optimized recharging of an electric battery of at least one electrical system by an electrical recharging device, said at least one electrical system being an electric vehicle,the method comprising:
- determining an available charging time period between a moment when the electrical recharging device is connected to the electric battery and a moment when the electrical recharging device is disconnected from the electric battery;
recharging the electric battery during at least one recharge interval within the available charging time period, said at least one recharge interval comprising k charging time intervals during each of which a respective charging power level is applied to recharge the electric battery;
wherein said respective charging power is determined by;
determining a residual electrical energy in the electric battery;
for each of the k charging time intervals;
sampling a load curve associated with the electrical recharging device over the available charging time period in order to obtain a set of load curve power values respectively associated with consecutive time intervals within the available charging time period;
sorting, in ascending order, the load curve power values in order to obtain a set of sorted load curve power values;
determining the respective charging power level of each of the k charging time intervals as a function of the residual electrical energy and of a k+1th load curve power value of the set of sorted load curve power values, the k charging time intervals being respectively associated with k first values of the set of sorted load curve power values.

Abstract
A method of optimized recharging of the electric battery of at least one electrical system by an electrical recharging device, in which the electric battery is recharged during at least one time interval by applying a charging power level associated with this time interval, this time interval belonging to an available charging time period initiated by the connecting of the recharging system of the electric battery to the electrical recharging device, and the charging power level being determined as a function of a charging curve associated with the electrical recharging device and of the residual electrical energy contained in the electric battery upon the connecting of the electric battery charging system to the electrical recharging device.
