Abstract
The invention relates to a process and device for charge transfer between a large number of identical energy stores (1) switched in series, whereby at least one electrical store (3) cuts in cycle alternately in parallel to the energy stores (1). Thereby, each electrical store (3) is formed from one transformer element (3) charged by the energy stores (1). The transformer elements (3) are switched at the mentioned cycle with alternating polarity in parallel to one of the identical energy stores (1) in such a way that all the identical energy stores (1) in each cycle step are switched singly in parallel to a transformer element (3), whereby a direct power flow is possible from one of the qualitatively good stores (1) to a store (3) with lower charge voltage. The process and the device can also be used for energy converters, e.g. in the form of fuel cells, for charge equalization purposes.
