Abstract

This creation is a “contactless charging device” with regard to a new contactless type and is applicable to the chargers for packaging and rechargeable batteries. The charger in itself is equipped with an ultrasound waves oscillator, in which the circuits is made output to an emission resonator to produce a powerful magnetic field and to radiate to the surrounding area of the charger. Moreover, within the battery packet charged is installed a receiving oscillator. The two sets of the oscillators resonate and induce the powerful magnetic field in the surrounding area of the charger and then a conversion is made into voltage and current, which are directly charged into the battery body in the battery packet. In this way, a charging effect is completed.

Claims

1. A “

contactless charging device”

consists of;

A charger, which is provided with a power line and can provide a charging status'"'"' is equipped with all ultrasound oscillator and an emission resonator and on its surface forms a loading area for a battery

2. A battery packet which is a battery pattern with a built-in receiving resonator;

In this way, the charger provides a charging pattern with a power line and its emission resonator can radiate the ultrasound waves of the ultrasound oscillator to the surrounding area of the charger. And place a rechargeable battery packet in the surrounding area of the charger and then the receiving resonator on the battery packet will be caused a resonating effect, i.e., being induced with the powerful magnetic waves in the surrounding area of the charger, and at once the conversion will be into voltage and current, which, through a set of rectifying circuits, are charged into the battery packet after being rectified. Thus the charging process is completed.
