Abstract

The invention relates to a charging system for charging an electronic device, wherein the electronic device comprises an electrical storage device. The charging system comprises a charging generator used for electrically connecting with an alternating current power supply, a charging receiver electrically connected with the electrical storage device and at least one magnetic core, wherein the charging generator comprises a first coil; the charging receiver comprises a second coil and a current converting and charging module which is electrically connected with the second coil and used for charging the electrical storage device; one of the first coil and the second coil is sleeved with the magnetic cores; and the second coil is coupled with the first coil. When the charging system needs tobe used for charging the electronic device, the electronic device is wirelessly charged through induction current generated on the second coil by coupling the first coil and the second coil. The charging system is convenient to use, and the magnetic cores can strengthen the electromagnetic induction intensity so as to improve the charging efficiency.

Description

technical field [0001] The invention relates to a charging technology, in particular to a wireless charging system. Background technique [0002] With the rapid development of communication technology, more and more people use various portable electronic devices, such as notebook computers and mobile phones, in their work and life. To improve portability, people usually use rechargeable batteries to power portable electronic devices. When the portable electric device needs to be charged, people can use a charger to charge it. The existing charger generally needs to connect the power supply and the portable electronic device to charge the rechargeable battery through a power cable, which is inconvenient to operate. In addition, portable electronic devices generally require specific and corresponding chargers. In this way, the user needs to carry the charger with him, otherwise, the rechargeable battery will be exhausted and the corresponding charger cannot be found in time...
