ABSTRACT:
A battery comprises a plurality of cells, in particular lithium-ion cells, connected in series and having two external connection contacts constituting charging/discharging contacts. A switch between the cells, in the electrical circuit connecting them, is open when the battery is being charged and closed when the battery is being discharged. On either side of each switch is an external charging contact for connection to a separate charging circuit for each cell. Each charging/discharging contact also constitutes a charging contact for the cell that is directly connected to it.
