Abstract
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.
