Embodiment 1

[0020] The power source 2 of the electromagnetic induction energy storage system may be alternating current or direct current, such as a battery. If the DC power supply is used, the high-frequency alternating magnetic field generating circuit 9 includes a high-frequency push-pull oscillator circuit. The high-frequency alternating magnetic field generating circuit 9 generally includes a coil, a resonant circuit, an amplifier circuit, and a functional control circuit 10 including a control circuit, an overcurrent detection circuit, and a feedback circuit.

[0021] The isotropic electromagnetic induction energy storage device 1 includes a magnet 3 , a high-frequency coil 4 , a filter and rectifier circuit 5 , and an electrical storage device 6 . The magnet is generally in the form of a cylinder, and can also be prismatic. The magnets are made of materials with low hysteresis coefficient, such as magnets, cobalt or nickel. The magnets are two perpendicular to each other, or thre...

Embodiment 2

[0026] The electromagnetic induction energy storage system connects medical devices placed in the human body. The medical devices placed in the human body include, but are not limited to, pacemakers, charge-coupled devices, artificial organs, electronic capsule endoscopes, and the like. These medical devices are widely used clinically. At present, the energy of these medical devices can only be powered by external wires or self-powered by internal batteries, which causes great inconvenience to patients.

[0027] Applying the electromagnetic induction energy storage system of the present invention, the high-frequency alternating magnetic field generating circuit 9 is placed outside the human body, and the electrical appliance 11, that is, the medical device, together with the isotropic electromagnetic induction energy storage device 1 and the power storage device 6 is placed inside the human body. The high-frequency alternating magnetic field generating circuit 9 emits a high-...

Abstract

The invention relates to an electromagnetic induction energy storage system, comprising an isotropy electromagnetic induction energy storage device and a high frequency alternating magnetic field producing circuit; the isotropy electromagnetic induction energy storage device is integrated with an electrical storage device and is connected with electrical appliance; the high frequency alternating magnetic field producing circuit is driven by power supply to produce a high frequency alternating magnetic field; when the isotropy electromagnetic induction energy storage device is close, producing current under the effect of electromagnetic induction; the isotropy electromagnetic induction energy storage device is further composed of a magnet, a high frequency coil, a filter rectification circuit, and an electrical storage device; the magnets are two, three, each of which are vertical to each other; the high frequency coil is divided into two or three groups to twist the magnet. The invention is provided with magnetic field acceptable isotropy design, which makes the magnetic field accept directional dead angle minimum, so as to improve coupling factor and electromagnetic conversion efficiency. The invention is appropriate for various electric devices, specifically the one as human body medical appliance hard to accomplish conventional contact charging.

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...
