Abstract
A method and apparatus for allowing charge exchange among a plurality of energy accumulators of the same type which are interconnected in series. At least one electric accumulator is cyclically and alternatively connected in parallel to the energy accumulators. Each electric accumulator consists of a capacitive element charged by the energy accumulators. The electric accumulators are also each cyclically connected in parallel to one of the energy accumulators, so that during each phase of the cycle al energy accumulators of the same type are individually connected in parallel to an electric accumulator thereby establishing a direct power flow from higher voltage accumulators to lower voltage accumulators. The method and apparatus may be used for equalizing the charge of energy accumulators, and energy converters.
