In a method for balancing an energy storage system, a capacitance of capacitive storage modules of a series circuit of capacitive storage modules is determined. The capacitive storage modules are connected to a balancing device to allow control of a charge of each of the capacitive storage modules via a flow of current between the balancing device and the capacitive storage modules. For each of the capacitive storage modules a module charge is determined from a voltage of the capacitive storage module and a predefined balancing voltage. A reference charge is determined from the module charges of the capacitive storage modules, and a balancing charge is determined for each of the capacitive storage modules from the reference charge and the module charge of the capacitive storage module. The charge of the capacitive storage modules is controlled by exchanging the balancing charge between the capacitive storage module and the balancing device.
