Abstract

L'invention concerne un dispositif bon marché pour charger des accumulateurs, en particulier pour ordinateurs bloc-notes, qui comporte une intelligence de calcul (MC) et un circuit de charge commandé par celle-ci. Ces deux composants sont reliés à une première unité de raccordement (EAE) d'un appareil de base (GG) associé, unité à laquelle peuvent être raccordées des unités d'adaptation (AE) qui conviennent chacune pour un type prédéterminé d'accumulateur à charger. Chaque unité d'adaptation (AE) présente, en vis-à-vis de la première unité de raccordement (EAE), une contre-prise (GS) telle que l'intelligence de calcul (MC) reconnaît le type de l'unité d'adaptation (AE) présente et règle en conséquence l'algorithme de charge.
