A charge-balancing device for balancing charge of an electrical power-storage device that has several series-connected electrical storage elements two DC/DC converters with current limitation, each having an input for receiving a set value of output voltage from the converter, an input to be connected to the terminals of a respective storage element, and an output to be connected to an electric network having a voltage regulated at a level below a voltage at the terminals of the power-storage device, and a control module. The control module is configured to determine respective residual charges of the electrical storage elements connected to the inputs and to apply a higher set value of voltage to the converter connected to an electrical storage elements that has a highest residual charge. |
