Abstract
A vehicular charging control system using a solar panel includes: a first battery; a calculation unit that calculates a chargeable electric power amount (an amount of electric power with which the first battery can be charged until the SOC of the first battery reaches a predetermined value); a determination unit that determines whether regenerative electric power is being generated; and a control unit that controls charging of the first battery with electric power generated by the solar panel. The control unit allows the first battery to be charged with the electric power generated by the solar panel up to an upper limit set to the chargeable electric power amount when regenerative electric power is not being generated, and up to an upper limit set to an electric power amount obtained by subtracting the regenerative electric power amount from the chargeable electric power amount when regenerative electric power is being generated.
