Abstract
A power-supplying system of a human-powered vehicle comprises a first electric power source and electronic controller circuitry. The first electric power source is electrically connectable with a photovoltaic unit to store electricity supplied from the photovoltaic unit. The electronic controller circuitry is electrically connectable with the photovoltaic unit and a second electric power source. The electronic controller circuitry is configured to charge the second electric power source in a first state using electricity which is supplied from the photovoltaic unit without passing through the first electric power source. The electronic controller circuitry is configured to charge the first electric power source in a second state using electricity supplied from the photovoltaic unit instead of charging the second electric power source.
