A vehicle-mounted solar power generation device includes a solar panel, a solar battery that is a battery temporarily storing electric power, and a controller configured to perform control by switching between an electric power generation mode in which the solar battery is charged with a generated electric power of the solar panel and an electric power saving mode in which at least the charging of the solar battery is stopped such that power consumption is suppressed in comparison with the electric power generation mode. The controller determines to switch between modes based on the output voltage of the solar panel. In the electric power saving mode, the controller restricts a switch to the electric power generation mode based on any of the frequency of switching between modes, the amount of electric power stored in the solar battery, and the state of stoppage of a vehicle.

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.

A wind-powered electric vehicle power regeneration system for increasing the range of electric vehicles. The system includes a twin turbine system with at least one fan on each turbine, and may include a vacuum-assisted turbine and gearbox. The twin turbine system preferably has three fans on each turbine. The fans may be of various sizes. The first and largest fan may be directly powered via the electric vehicle motor, which may create a vacuum. The second fan may partially be powered by the EV motor, while also being moved by the vacuums suction and the air that enters the compartment. The third fan may rotate via force of air entering the compartment. All of the fans may be connected to a central gearbox located beneath them. The gearbox may be connected to a generator that may be connected to a capacitor that charges an electric vehicle's battery.
