Ce procédé consiste à détecter, parmi une pluralité de dispositifs de charge (10, 30, 50, 70), les dispositifs de charge (10, 30, 50) qui, au moment de la détection (t1), sont raccordés électriquement à un véhicule (18, 38, 58) pour la charge de la batterie de propulsion (16, 36, 58) de celui-ci. Pour chaque dispositif de charge (10, 30, 50), un paramètre de priorité respectif (P1, P2, P3), attribué au moins temporairement au véhicule raccordé au dispositif de charge ou à l'utilisateur de celui-ci, est déterminé.
