Title (EN) METHOD TO REUSE THE PULSE DISCHARGE ENERGY DURING LI-ION FAST CHARGING FOR BETTER POWER FLOW EFFICIENCY
(FR) PROCÉDÉ DE RÉUTILISATION DE L'ÉNERGIE DE DÉCHARGE D'IMPULSION PENDANT UNE CHARGE RAPIDE LI-ION PERMETTANT UNE MEILLEURE EFFICACITÉ DE FLUX D'ÉNERGIE
Abstract:
(EN) A battery charger for charging a battery with voltage from an input supply and method for using are disclosed. In one embodiment, the battery charger comprises a power path to drive the battery during a pulse charging sequence in a first mode and to reverse power flow from the battery when operating in a boost mode during the pulse charging sequence and an energy storage component coupled to the power path to capture pulse discharge energy during the pulse charging sequence when the circuit stage is operating in the boost mode.
(FR) La présente invention concerne un chargeur de batterie permettant de charger une batterie avec une tension à partir d'une alimentation d'entrée et un procédé d'utilisation. Dans un mode de réalisation, le chargeur de batterie comprend un trajet d'alimentation permettant d'entraîner la batterie pendant une séquence de charge d'impulsion dans un premier mode et d'inverser le flux d'énergie provenant de la batterie lorsqu'il fonctionne dans un mode d'amplification pendant la séquence de charge d'impulsion et un composant de stockage d'énergie couplé au trajet d'alimentation permettant de capturer l'énergie de décharge d'impulsion pendant la séquence de charge d'impulsion lorsque l'étage de circuit fonctionne dans le mode d'amplification.
