CHARGING SYSTEM FOR AN ENERGY STORE

摘要

The invention relates to a charging system comprising an energy store (7) for storing electric energy and a charger (6) to be connected in a three phase manner for charging the energy store from a three-phase supply network (1, 2, 3), wherein the charger (6) has a power factor correction filter and the direct voltage output by the charger lies above the peak voltage of the supply network, and wherein the input voltage of the energy store lies in the range of the direct voltage output by the charger (6), wherein said charging system further comprises means (10, 20-23, 30, 31, 40, 41) for charging the energy store from a state of deep discharge to a state in which the charger (6) can be used to carry out further charging.
