Title:
WHOLE-PROCESS DYNAMIC ENERGY RECOVERY EXTENDED RANGE SYSTEM AND EXTENDED RANGE METHODS FOR PURE ELECTRIC BICYCLES
Document Type and Number:
WIPO Patent Application WO/2016/173033
Kind Code:
A1
Abstract:
A whole-process dynamic energy recovery extended range method for pure electric bicycles, comprising: a power battery pack (14) supplies power for a hub motor so as to drive an electric bicycle to go forward in an accelerating way; when the electric bicycle is accelerated to travel at an upper limit speed, disconnect the power supply, and a hub electric generator (21) converts kinetic energy of a driven wheel (13) into electric energy and uses same to charge the power battery pack (14); and when the electric bicycle is slowed down to travel at a lower limit speed, start to supply power, and so on. Another extended range method comprises: in a riding process, a hub electric generator (21) converts kinetic energy of a driven wheel into electric energy and transmits same to an extended range controller (22); and the extended range controller (22) utilizes the electric energy transmitted by the hub electric generator (21) to supply power for its own and/or outputs same to a power battery pack (14) for charging the power battery pack. An extended range system, comprising a driving wheel (12), a driven wheel (13), a system controller (11), a power battery pack (14) and an extended range controller (22), a hub motor being installed on the driving wheel (12), and a hub electric generator (21) being installed on the driven wheel (13). The extended range methods and the extended range system realize charging while riding, and have a stable extended range effect.
