Storage module

A power supplying/receiving system for a vehicle comprising:

• a system control computer;
• a plurality of storage module groups each including a plurality of storage means for storing electric energy, the plurality of storage means electrically connected in each of the plurality of storage module groups, the plurality of storage module groups each including energy transfer means for transferring the electric energy among the plurality of storage means to keep a charging voltage across each of the storage means at a value according to a predetermined ratio, the plurality of storage module groups each including coupling means for coupling the storage module group to another storage module group mechanically, the plurality of storage module groups each including a connection terminal to which a drive signal is input;
• a supplying/receiving control section for receiving an order from the system computer and controlling voltages among the plurality of storage module groups on the basis of the order from the system control computer, the supplying/receiving control section for supplying the electric energy to a load;
• a charger for supplying the electric energy to the supplying/receiving control section,
• wherein the energy transfer means includes a plurality of series circuits each having at least a first winding and switching means connected in series, each of the plurality of series circuits is adapted to be connectable in parallel to each of the plurality of storage means, the plurality of first windings are magnetically coupled with one another, and the plurality of switching means are switching-controlled synchronously with one another, and
• wherein the drive signal switches the switching means of the storage module groups synchronously with one another.
