Abstract

L'invention porte sur un système et sur un procédé pour la commande, d'une manière externe, de la charge d'un dispositif informatique mobile alimenté par batterie, lesquels système et procédé comprennent une unité de charge configurée pour être couplée électriquement au dispositif informatique mobile pour charger une batterie dans celui-ci. L'unité de charge comprend un chargeur configuré pour fonctionner dans un premier mode pour fournir un courant de charge constante à la batterie à charger et fonctionner dans un second mode pour fournir une tension de charge constante à la batterie à charger et où le commutateur du premier mode au second mode intervient lorsque la tension au niveau de la batterie atteint une tension de seuil prédéfinie. Le chargeur comprend un compensateur de décalage configuré pour appliquer une tension de décalage à la sortie mesurée du chargeur en vue de maintenir le chargeur dans le premier mode pour compenser les chutes de tension entre le chargeur et la batterie, permettant ainsi à la tension de batterie d'atteindre la tension de seuil.
