1. Method that consists to give a second life to used electric vehicle battery packs by reusing them as a power source for an autonomous battery charger,
wherein the method includes successive steps consisting in:
a. selecting, among battery packs that have been removed from electric vehicles, at least two battery packs;
b. balancing the voltage between the selected battery packs, in order that the selected battery packs have the same State Of Charge (SOC); and
c. integrating the selected battery packs into the battery charger.
