Abstract

The invention relates to an electromagnetic conversion energy storage system comprising an isotropic electromagnetic induction energy storage device and a high-frequency alternating magnetic field generation circuit. The isotropic electromagnetic induction energy storage device and a power storage device are integrated and connected with electrical appliances. The high-frequency alternating magnetic field generation circuit generates a high-frequency alternating magnetic field under the drive of a power supply. When the isotropic electromagnetic induction energy storage device approaches, a current is generated under the action of electromagnetic induction. The isotropic electromagnetic induction energy storage device comprises magnets, high-frequency coils, a filter and rectifier circuit, and a power storage device. Of the two or three magnets, every two magnets are perpendicular to each other. The high-frequency coils wind the magnets in two or three sets. By using the magnetic field reception isotropy design, the dead angle in the magnetic field reception direction is minimized, and thus, the coupling coefficient and electromagnetic conversion efficiency are improved. The electromagnetic conversion energy storage system is applicable to various electrical appliances, and especially applicable to traditional contact-charging electrical appliances which are hard to implement such as medical instruments in the human body.

Description

technical field [0001] The invention relates to an energy storage charging device, in particular to an energy storage charging device using electromagnetic induction. Background technique [0002] In this era of electrification, the use of rechargeable batteries has become quite widespread. Traditional charging and energy storage technologies for rechargeable batteries are realized by directly contacting the positive and negative poles of the power supply with the rechargeable battery. This charging technology is still widely used at present. It has the problem of electricity safety, and there are also disadvantages such as poor electrode contact, many types of chargers with different specifications, and cannot be used universally, and the use of electrical appliances is restricted due to the involvement of wires during charging. [0003] Chinese invention patent application 200510085491.5 discloses an "isolated charging system and its application" (publication number: CN1...
