Title (EN) BATTERY MANAGEMENT
(FR) GESTION DE BATTERIE
Abstract:
(EN) A battery management system (103) for a battery (100) comprising a plurality of battery cells (101, 102) connected in parallel with each other. The battery management system comprises an electronic circuit (104) for connection across at least one of the plurality of battery cells. The electronic circuit comprises a charge storage device (105) and a switching device (106). The switching device switches the circuit between a first state in which charge is discharged from the at least one battery cell and directed to the charge storage device and a second state in which charge is discharged from the charge storage device and directed to the at least one battery cell. The switching device is arranged to repeatedly switch the circuit between the first state and the second state to cause the at least one battery cell to undergo pulsed charging and discharging to and from the charge storage device.
(FR) Un système de gestion de batterie (103) pour une batterie (100) comprend une pluralité de cellules de batterie (101, 102) connectées en parallèle les unes aux autres. Le système de gestion de batterie comprend un circuit électronique (104) destiné à être connecté à travers au moins une cellule de la pluralité de cellules de batterie. Le circuit électronique comprend un dispositif de stockage de charge (105) et un dispositif de commutation (106). Le dispositif de commutation commute le circuit entre un premier état dans lequel une charge est déchargée à partir de ladite ou desdites cellules de batterie et dirigée vers le dispositif de stockage de charge et un second état dans lequel une charge est déchargée du dispositif de stockage de charge et dirigée vers la ou les cellules de batterie. Le dispositif de commutation est conçu pour commuter de manière répétée le circuit entre le premier état et le second état pour amener la ou les cellules de batterie à subir une charge et une décharge pulsées vers et depuis le dispositif de stockage de charge.
