SYSTEM FOR CHARGING BATTERY AND SUPPLYING ELECTRIC POWER USING WIRELESS COMMUNICATION

摘要

PURPOSE: A system for charging a battery and supplying electric power using wireless communication is provided to conveniently charge a battery and use a power transmission function by eliminating obstacles when a battery is charged and an electronic device is driven. CONSTITUTION: A power transmission unit transmits electrical energy by using electromagnetic resonance from an energy source. A power reception unit receives the power transmitted from the power transmission unit. A charging unit is charged with the electrical energy received from the power reception unit. The charging unit is electrically connected to the power reception unit. A power transmission frequency transmitted from the power transmission unit is distributed to two bands of a LF(Low Frequency) and a HF(High Frequency) or three bands of the LF, a MF(Middle Frequency), and the HF.
