Description
Technical field
The utility model relates to a kind of charger, particularly a kind of intelligent charger.
Background technology
Present storage battery is used charger; Mainly being the charger of linear regulation mode, is that volume is big although use the subject matter of commonplace existence, and consumed power is big; Be prone to heating; Particularly more outstanding when to batteries charging, charger adopts constant current mode to charge basically and with the method that the charging interval termination is charged, generally is designed with certain surplus for preventing to overcharge at present.Therefore, most batteries are not fully filled, and are not fully filled to make the battery can not electricity performance maximum efficiency, still can cause when big and overcharge but be recharged the pond residual capacity, overcharge the useful life that influences battery.
The utility model content
In order to overcome the above-mentioned weak point that exists in the prior art; The purpose of the utility model is to provide a kind of intelligent charger; This intelligent charger can be discerned the electric pressure that is recharged battery pack automatically; Use more conveniently and more reliable, can not cause the damage of battery or charger because of improper use.
In order to reach above-mentioned purpose; The utility model adopts following concrete technical scheme: a kind of intelligent charger; Comprise that the AC input connects filter circuit, rectifying and wave-filtering, HF switch converter successively, transfers wide square wave rectifying and wave-filtering, DC output; The input of said HF switch converter connects pulse width modulation circuit, and the input of said pulse width modulation circuit connects oscillating circuit and comparison circuit, and said comparison circuit input connects cell voltage identification circuit, charging current sampling restriction and reference voltage; The input of said cell voltage identification circuit is connected on the L power supply of DC output; Said charging current sampling restriction input be connected on the N power supply of DC output, said comparison circuit output connects the charged state indicating circuit, said DC output connects rechargeable battery.
Compared with prior art; The utlity model has following outstanding advantage and effect: this intelligent charger can be discerned the electric pressure that is recharged battery pack automatically; Improved the useful life of storage battery greatly, solving the automation controller system is the possibility of forgetting that charging causes system to work because of the people.
Description of drawings
Fig. 1 is the theory diagram of the utility model.
Below in conjunction with accompanying drawing the utility model is done further to specify.
Embodiment
As shown in Figure 1; A kind of intelligent charger; Comprise that the AC input connects filter circuit 1, rectifying and wave-filtering 2, HF switch converter 3 successively, transfers wide square wave rectifying and wave-filtering 4, DC output, the input of said HF switch converter 3 connects pulse width modulation circuit 5, and the input of said pulse width modulation circuit 5 connects oscillating circuit 10 and comparison circuit 6; Said comparison circuit 6 inputs connect cell voltage identification circuit 7, charging current sampling restriction 8 and reference voltage 9; The input of said cell voltage identification circuit 7 is connected on the L power supply of DC output, said charging current sampling restriction 8 input be connected on the N power supply of DC output, said comparison circuit 6 outputs connect charged state indicating circuit 11; Said DC output connects rechargeable battery 12; This intelligent charger can be discerned the electric pressure that is recharged battery pack automatically, and in the useful life of having improved storage battery greatly, solving the automation controller system is the possibility of forgetting that charging causes system to work because of the people.
What should explain at last is: above embodiment is only unrestricted in order to the technical scheme of explanation the utility model; Although the utility model is specified with reference to preferred embodiment; Those of ordinary skill in the art is to be understood that; Can make amendment or be equal to replacement the technical scheme of the utility model, and not break away from the spirit and the scope of the utility model technical scheme, it all should be encompassed in the middle of the claim scope of the utility model.
