When the resistance very big in a resistance value, electric current is decayed in transmittance process, finally after tertiary coil 313 circuit to nothing
Line receiving coil 18.It can be seen that only fraction electric current is slowly charged into rechargeable battery 16 when charging to 80%, this
Sample can protect rechargeable battery 16, avoid self discharge caused by overcharging, and effectively improve the service life and drop of rechargeable battery 16
The decaying of low 16 capacity of rechargeable battery.In the present embodiment, the last the first magnetic 17 and the last the second magnetic 312 are magnetic very strong magnetic
Iron, their magnetic induction intensity are all larger than 1T(tesla), neodymium iron boron strong magnet can be used for example.Preferably, the last the first magnetic
Magnetic induction intensity be 1.28T to 1.32T, the magnetic induction intensity of the last the second magnetic is 1.13T to 1.17T.
Certainly, above-described embodiment is only the preferable embodiment of the utility model, and when practical application can also have more
Variation, within the spirit and principle of the utility model, any modification, equivalent substitution, improvement and etc. done should be included in
In the protection scope of the utility model claims.
