Abstract

An electric power supply system includes an electric power reception apparatus and an electric power supply apparatus adapted to supply electric power to the electric power reception apparatus when the electric power reception apparatus is placed on the electric power supply apparatus. The electric power supply apparatus includes a plurality of electric power supply units adapted to supply electric power by electromagnetic induction to the electric power reception apparatus. A selection unit of the electric power supply apparatus selects, from the total plurality of electric power supply units, a plurality of electric power supply units whose location corresponds to a position where the electric power reception apparatus is placed, and a control unit controls the supply of electric power such that electric power is supplied to the electric power reception apparatus from the selected plurality of electric power supply units.
