Abstract
The invention relates to a method for charging energy storage cells of an energy storage device with a plurality of energy storage modules which are connected in series in an energy supply line, each energy storage module comprising an energy storage cell module which has at least one energy storage cell and comprising a coupling device with coupling elements. The coupling elements are designed to selectively connect the energy storage cell module in the energy supply line or to bridge the energy storage cell module. The method consists of the following steps: coupling the output connections of the energy storage device to a DC voltage source, controlling the coupling devices of all the energy storage modules in order to bridge the energy storage cell modules in the energy supply line for a first specified period of time, and controlling the coupling devices of at least one first energy storage module in order to connect the energy storage cell module of the first energy storage module in the energy supply line for a second specified period of time after the first specified period of time has elapsed.
