Magnetic flywheel energy management system and method

An energy management device comprising:

• at least one rotary flywheel electric energy management device comprising two shafts;
• each said shaft comprising a smaller circumference end and a larger circumference end;
• each said smaller circumference ends being suspended on low friction magnetic bearings;
• said two shafts configured to join together at their larger circumference ends to form at least one cavity that encases a flywheel mass;
• said flywheel mass comprising a plurality of permanent magnets arranged in any of an axial or radial configuration;
• said shafts further surrounded by at least one stator comprising a plurality of magnetic pickup coils arranged and electrically connected in a stator configuration, said at least one stator configured so that said shafts can rotate freely within said at least one stator;
• said magnetic pickup coils and said at least one stator configured so that when said flywheel mass rotates, changing magnetic fields from said plurality of permanent magnets causes electrical current to flow within said plurality of magnetic pickup coils and said at least one stator;
• and at least one electric motor configured to apply torque, via magnetic coupling, to at least one smaller circumference end of at least one said shaft to spin said shaft and said flywheel mass;
• each said at least one rotary flywheel electric energy management device further configured to store input electrical energy as flywheel rotational kinetic energy, and to convert said flywheel rotational kinetic energy into output electrical energy;
• wherein each shaft is a substantially conical hollow shaft, said conical hollow shafts comprise any of a composite material or a carbon fiber material, said permanent magnets comprise rare earth permanent magnets, and said flywheel mass comprises a mass of over 100 pounds;
• wherein said flywheel mass and said at least one stators are further surrounded by at least one safety shield;
• and further comprising a battery storage system device and an energy control processor.
