Abstract
A method of recycling motor power of a movable object is provided to recycle and redistribute power from at least one motor in a decelerating state. The method comprises determining whether an operating state of at least one motor of the movable object is a decelerating state, and recycling power from the at least one motor having a decelerating state. The method also comprises redistributing the recycled power to other power consuming components of the movable object. The method of present invention increases the energy efficiency and a battery life of the movable object. The movable object may be an unmanned aerial vehicle (UAV).

A method of power recycling for an unmanned aerial vehicle (UAV), said method comprising:
- determining, with aid of a processor, operating states of a plurality of motors of the UAV, wherein the plurality of motors are used to drive the UAV, and wherein at least one motor in a decelerating state is configured to work in concert with at least one other motor in an accelerating state to effect rotation of the UAV;
- collecting power from the at least one motor when the operating state of the at least one motor is the decelerating state;
- and
- distributing the power collected from the at least one motor in the decelerating state directly to the at least one other motor in the accelerating state during the rotation of the UAV.
A system of power recycling for an unmanned aerial vehicle (UAV), said system comprising:
- a plurality of motors of the UAV that are configured to drive the UAV, wherein at least one motor in a decelerating state is configured to work in concert with at least one other motor in an accelerating state to effect rotation of the UAV;
- one or more processors configured to, individually or collectively, determine operating states of the plurality of motors of the UAV;
- at least one energy converter configured to collect power from the at least one motor when the operating state of the at least one motor is the decelerating state;
- and
- a power supplier configured to distribute the power collected from the at least one motor in the decelerating state directly to the at least one other motor in the accelerating state during the rotation of the UAV.
A system of power recycling for an unmanned aerial vehicle (UAV), said system comprising:
- a plurality of motors of the UAV that are configured to drive the UAV, wherein at least one motor in a decelerating state is configured to work in concert with at least one other motor in an accelerating state to effect rotation of the UAV;
- and
- a power bus electrically connected with the plurality of motors in parallel, wherein the power bus is configured to (i) collect power from the at least one motor in the decelerating state, and (ii) provide a portion of the collected power to the at least one other motor in the accelerating state during the rotation of the UAV.
A power management system of an unmanned aerial vehicle (UAV), said power management system comprising:
- a plurality of motors of the UAV that are configured to drive the UAV, wherein at least one motor in a decelerating state is configured to work in concert with at least one other motor in an accelerating state to effect rotation of the UAV;
- one or more processors configured to, individually or collectively, determine operating states of the plurality of motors of the UAV;
- and
- a power bus electrically connected with the plurality of motors and a power consuming unit in parallel, wherein the power bus is configured to redistribute power collected from the at least one motor to the power consuming unit when the operating state of the at least one motor is the decelerating state.
