Vorrichtung zur Aufladung und zum Ladungsaustausch zwischen einer Vielzahl von in Reihe geschalteten Energiespeichern

The system uses at least one electrical storage device (3), cyclically connected in parallel with the batteries (1), provided by a transformer element, charged by the batteries. During the charging process, the energy storage device is switched for cyclically acting as the secondary coil of a transformer having a primary coil (23) wound on the same core and during the charge transfer process, the energy storage device is switched for acting as a transmission coil in which a voltage is induced by the entire battery set. USE - For traction battery set in electric vehicle.
