Revert to channel status between interface 10 and charging circuit 30, continue with civil power and battery is charged.
Delays time to control by control circuit 50, it is ensured that in battery charging process, battery capacity indication lamp is changed to the second shape
State outwardly shows when the electricity of current battery has been filled with, under the state that battery remains at charging so that battery can be continued
Continuous charging, improves the electricity saturation of battery.And after battery is really full of, by switching 40 breaking circuits, it is achieved that
Real stopping charging, it is ensured that charging safety, extends the service life of battery.The timing length of control circuit 50,
For different batteries different, can be configured by Theoretical Calculation or use experience, it is ensured that battery can
It is saturated charging, namely can be full of veritably.In embodiment of the present utility model, control circuit 50 also includes timing
Adjust circuit, be used for adjusting the timing length of control circuit 50.
Detected by the voltage on the cathode output end Vout to charging circuit 30, and judging cathode output end
When voltage on Vout is less than the voltage threshold preset, turn on charging circuit, it is ensured that battery in use will not enter
Enter the state that electricity is too low, effectively protect battery, extend the operation instruction of battery.
In embodiment of the present utility model, charging circuit 30 is connected with control circuit 50, detects at charging circuit 30 and fills
When electricity electric current is more than current threshold, the signal of telecommunication between charging circuit 30 and control circuit 50 is low level signal.In charging
Circuit 30 detects when charging current is less than or equal to current threshold, the signal of telecommunication between charging circuit 30 and control circuit 50
For high level signal.This high level signal is aforesaid battery and is full of signal.
Although the embodiment disclosed by this utility model is as above, but described content only readily appreciates this utility model technology
Scheme and the embodiment that uses, be not limited to this utility model.Technology people in any this utility model art
Member, on the premise of without departing from the spirit and scope disclosed by this utility model, can be carried out in the form implemented and details
Any amendment and change, but scope of patent protection of the present utility model, the model that still must be defined with appending claims
Enclose and be as the criterion.
