Abstract

L'invention porte sur un dispositif de commande (46) pour un véhicule avec un dispositif de stockage d'électricité embarqué (10), ledit dispositif de stockage d'électricité étant conçu de façon à être apte à être chargé à partir de l'extérieur du véhicule, limite le fonctionnement d'un dispositif de climatisation (80) si la quantité d'électricité restant dans le dispositif de stockage d'électricité (10) chute à un premier seuil en tant que résultat du fait que le dispositif de climatisation (80) fonctionne tandis que le dispositif de stockage d'électricité (10) est chargé. Après que le dispositif de climatisation (80) a été arrêté, le dispositif de commande redémarre l'opération de prélimitation dudit dispositif de climatisation (80) si la quantité d'électricité restant dans le dispositif de stockage d'électricité augmente à nouveau vers un second seuil, qui est supérieur au premier seuil mentionné ci-dessus.
