Abstract
An emergency power supply device for a rotor blade adjustment system of a wind turbine is disclosed. The emergency power supply device includes a plurality of electric power accumulators and a plurality of electric charging units. The number of charging units corresponds to the number of electric power accumulators. An electric circuit is operable to electrically couple each of the electric charging units to a plurality of the electric power accumulators and each of the electric power accumulators to a plurality of the charging units.
