The power supply system includes a plurality of power supply apparatuses installed at a road at surroundings of an area in which operation of internal combustion engines is prohibited or restricted and configured so as to transmit power to vehicles by non-contact. The plurality of power supply apparatuses include a first power supply apparatus installed at a first point where a distance of a running route up to an entrance of the area or a straight route up to the entrance or a boundary of the area is equal to or less than a predetermined distance, and a second power supply apparatus installed at a second point where the distance is greater than the predetermined distance. An amount of power supply to a vehicle from the first power supply apparatus is made greater than an amount of power supply to a vehicle from the second power supply apparatus.

A charging system includes a scalable power source for powering a motor of a vehicle and telematics and battery management modules. The scalable power source includes: N battery packs, where N is an integer greater than or equal to 3; and multiple switches connected to the N battery packs including N−1 switches for serially connecting the N battery packs between supply and return lines and a multiple of N switches for parallel connecting the N battery packs to the supply and return lines. The telematics module requests capability of a charging station and receives a response signal from a device indicating the capability of the charging station. The battery management module: based on the capability of the charging station, selects one of the available arrangements in which to connect the N battery packs, sets states of the multiple switches; and then charges the N battery packs based on the states.

An electric vehicle includes a power receiver and a controller. The power receiver is configured to wirelessly receive electric power from power transmission equipment disposed outside the vehicle. The controller is configured to control power transmission from the power transmission equipment to the power receiver. The controller includes a determination processor and a frequency control unit. The determination processor is configured to make a determination, in a case where the power transmission is stopped due to a foreign object present between the power transmission equipment and the vehicle, as to whether the power transmission is restartable with a predetermined frequency after the power transmission is stopped. The frequency control unit is configured to change the frequency with which the determination processor makes the determination.

An electric vehicle solar charging system is disclosed, comprising a photovoltaic system or a DC source to transmit DC electricity to an electric vehicle via DC/DC conversion system. The DC/DC conversion is configured to directly transmit power to a battery pack configured to power the electric vehicle through the electric vehicle's DC charging inputs. This electricity can be supplemented by building battery or energy storage systems with DC output, or by DC electricity converted from AC which was supplied by AC sources. The combined circuit can be further modified by an in-line DC/DC converter at output if necessary, which also may be a bidirectional converter to supply energy from the EV back to the house load through a connected AC/DC inverter. When no DC is available, an AC power source can optionally provide supplemental power to the electric vehicle directly through the AC charging inputs.
