Power feeding equipment of electromotion bike

摘要

The present invention relates to an electric bicycle, and more particularly, in a conventional electric bicycle that is driven by driving power to a motor by a battery, provided with a battery module and a generator comprising a pair of batteries, the pair of When each battery output voltage reaches a certain level, a pair of batteries can be selectively connected to the motor and generator to alternately charge by the operation of the motor and the pedal. The present invention relates to an electric bicycle power supply device that maintains the state of charge as much as possible to maximize the operating efficiency of the electric bicycle. The present invention is installed on one side of the gear assembly is a power transmission to the rear wheel through the main chain when the pedal is driven in the electric bicycle equipped with a motor that receives the charging power from the battery and transmits the rotational force to the gear assembly and the pedal, the battery Is composed of a battery module consisting of a pair of first and second batteries, a generator for supplying charging power to the first and second batteries is installed on one side of the frame of the electric bicycle, the generator shaft of the generator and Gear shafts of the other end of the gear assembly are connected to each other by an auxiliary chain, and a charge and discharge control circuit for selectively charging and discharging the power generated from the generator to the first and second batteries alternately.
