1. A transport refrigeration system comprising:
a transportation refrigeration unit;
an energy storage device configured to provide electrical power to the transportation refrigeration unit; and
an electric generation device operably connected through a mechanical interface to at least one of a wheel of the transport refrigeration system and a wheel axle of the transport refrigeration system;
wherein the mechanical interface comprises:
a first clutch mechanism operable to selectively engage the electric generation device with at least one of the wheel and the wheel axle to generate electrical power to charge the energy storage device; and
a second clutch mechanism, wherein the second clutch mechanism is an overrunning clutch configured to disengage the electric generation device from the wheel and/or the wheel axle when a rotational velocity of the electric generation device is greater than a rotational velocity of the wheel and/or the wheel axle.
