SYSTEM AND METHOD FOR CHARGE BALANCING AND/OR CHARGING ELECTRICAL ENERGY-STORING UNITS

摘要

The invention on one hand relates to a system for the charge balancing and/or charging of electrical energy- storing units (10) connected in series, which system comprises centrally controlled energy- control units (12) interconnected between the poles of the individual energy- storing units (10), which energy- control units (12) are provided with a control circuit and an energy- transfer circuit. The energy transmitting circuits are connected to a feed conductor (22) attached to the alternating current energy source, and comprise an energy- transfer capacitive element (24) being connected to the feed conductor (22) and enabling energy flow between the alternating current energy source and the given energy- storing unit (10), as well as a switching means suitable for realizing selective energy transfer being operated by the control circuit (40).
