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).
Claims30
A method of power recycling for a movable object, said method comprising:
- determining, with aid of a processor, an operating state of at least one motor of the movable object, wherein the at least one motor is used to drive the movable object;
- and
- recycling power from the at least one motor when an operating state of the at least one motor is a decelerating state.
A system of power recycling for a movable object, said system comprising:
- at least one motor of the movable object configured to drive the movable object;
- one or more processors configured to, individually or collectively, determine an operating state of the at least one motor of the movable object;
- and
- at least one energy converter configured to recycle power from the at least one motor when the at least one motor has an operating state that is a decelerating state.
A system of power recycling for a movable object, said system comprising:
- a plurality of motors of the movable object, each configured to drive the movable object;
- and
- a power bus in electrical connection with the plurality of motors, wherein the power bus is configured to receive power from the at least one motor when the at least one motor is decelerating and provide power to at least one motor of the plurality of motors when the at least one motor is accelerating.
A power management system of a movable object, said power management system comprising:
- at least one motor of a movable object configured to drive the movable object;
- one or more processors configured to, individually or collectively, determine an operating state of the at least one motor of the movable object;
- and
- at least one energy distribution unit configured to redistribute power from the at least one motor to a power consuming component of the movable object when the an operating state of the at least one motor is a decelerating state.
