System and method for recovering wasted kynetic energy in a vehicle

A wasted kinetic energy recovery system, comprising:

• a first rotatable assembly, attachable to a vehicle wheel assembly to rotate jointly with the vehicle wheel assembly about a wheel rotation axis of the vehicle wheel assembly, the first rotatable assembly comprising a first plurality of magnets;
• a bearing, mountable to the first rotatable assembly;
• a second rotatable assembly, mountable to the bearing, the second rotatable assembly comprising a second plurality of magnets and one or more rotor magnets;
• and
• a stationary assembly comprising a stator, wherein
• the wasted kinetic energy recovery system is configured to adopt a working configuration in which:
• the stationary assembly is mounted about the wheel axle of the vehicle wheel assembly and is non-rotatable about the wheel rotation axis,
• the first rotatable assembly is attached to the vehicle wheel assembly and is driven for rotation about the wheel rotation axis by and jointly with the vehicle wheel assembly,
• the bearing is mounted to the first rotatable assembly, and
• the second rotatable assembly is mounted to the bearing and about the wheel axle and rotates about the wheel rotation axis with respect to the first rotatable assembly, the vehicle wheel assembly and the stationary assembly, wherein rotation of the second rotatable assembly with respect to the first rotatable assembly, the vehicle wheel assembly and the stationary assembly is enabled by the bearing and driven by a first magnetic field produced between the first plurality of magnets of the first rotatable assembly and the second plurality of magnets of the second rotatable assembly, said rotation of the second rotatable assembly and of the one or more rotor magnets comprised therein producing an electrical current in the stator;
• and
• the wasted kinetic energy recovery system is configured to automatically switch from the working configuration to an additional working configuration as a result of the first rotatable assembly and wheel rotation assembly ceasing to rotate with respect to the wheel rotation axis;
• wherein,
• in the additional working configuration:
• the second rotatable assembly continues to rotate about the wheel rotation axis with respect to the first rotatable assembly, the vehicle wheel assembly and the stationary assembly, wherein rotation of the second rotatable assembly is driven by inertia, said rotation of the second rotatable assembly and of the one or more rotor magnets comprised therein producing an electrical current in the stator.
