Description
Technical field
The invention belongs to generating, power transformation or distribution technique field, especially relate to a kind of converter and improve from the battery adaptive charger that ac mains is batteries charging.
Background technology
Battery charger is electric motor car, electric tool, electronic game, notebook, number and small portable electronic device and electronic apparatus rechargeable battery charging used electronic equipment, is generally made up of shell, Power convert part, charging test section, charge protection part etc.Its output type is pure direct current or pulsating direct current.Direct Plug-In and Table top type can be divided into by connected mode.Ni-Cd battery charger, nickel-metal hydride battery charger, nickel-zinc cell charger, lead-acid battery charger, lithium battery charger etc. can be divided into again by the type of institute's rechargeable battery.Special charger and universal charger can be divided into again by the function of charger.
In life, we touch very eurypalynous rechargeable battery, have Ni-MH battery, lithium battery etc.Ni-MH battery is with the price of its relative moderate and allow the characteristic of heavy-current discharge to make its popularity rate very high, and lithium battery is then commonly used in the mini-plants such as mobile phone by the profile that its high-energy-density is small and exquisite.But the different method for charging batteries of type is different, usually will be equipped with several chargers, this brings very large inconvenience to our life.
Summary of the invention
The present invention is exactly for the problems referred to above, provides a kind of and automatically can identify battery and a kind of battery adaptive charger of charging.
For achieving the above object, the present invention adopts following technical scheme, the present invention includes detection module, discrimination module, processor, relay-operated controller, display, constant current charge module, pressurizer, output port, it is characterized in that: detection module, discrimination module are connected with processor, and processor is connected with relay-operated controller; Relay-operated controller is connected with display, constant current charge module, pressurizer; Pressurizer is connected with output port.
As a kind of preferred version, processor of the present invention is PIC877 single-chip microcomputer.
Beneficial effect of the present invention.
Detection module of the present invention, discrimination module are connected with processor, and processor is connected with relay-operated controller; Relay-operated controller is connected with display, constant current charge module, pressurizer; Pressurizer is connected with output port.External circuits of the present invention is simple, the advantage of Ni-MH battery and the public application circuit of lithium battery, in conjunction with the PIC877 single-chip microcomputer of high performance-price ratio.Make control section not only simple but also practical.Simultaneously through the actual test of experimental circuit, form AC/DC translation circuit by power transformer, rectification circuit, filter circuit and voltage stabilizing circuit, can charge to single battery battery easily under PIC coordinates control.
Accompanying drawing explanation
In order to make technical problem solved by the invention, technical scheme and beneficial effect clearly understand, below in conjunction with the drawings and the specific embodiments, the present invention is further elaborated.Should be appreciated that embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Fig. 1 is schematic block circuit diagram of the present invention.
Embodiment
As shown in the figure, the present invention includes detection module, discrimination module, processor, relay-operated controller, display, constant current charge module, pressurizer, output port, it is characterized in that: detection module, discrimination module are connected with processor, and processor is connected with relay-operated controller; Relay-operated controller is connected with display, constant current charge module, pressurizer; Pressurizer is connected with output port.
Described processor is PIC877 single-chip microcomputer.
For not knowing that the battery of chemical property charges, charger has needed the identification to institute's rechargable battery, and then charges.The difference on voltage of lithium battery and Ni-MH battery clearly.In single-chip microcomputer, arrange voltage threshold qV is 2V, starts charging front to cell voltage sampling Detection, as V<qV, is judged to be Ni-MH battery, is judged to be lithium battery during V>qV.Then different charging methods is taked for different battery.
Ni-MH battery adopts the method for constant current charge to charge, charge complete flag is-Δ V, namely battery terminal voltage declines, and-Δ V=(6 ~ 15) mV/ saves, need to control battery temperature climbing d θ/dt >=1 DEG C/joint simultaneously, because the change of temperature is easily affected by environment, be thus actually used in and differentiate that the variable in charging each stage is mainly-Δ V, θ max, wherein the detection of p-Δ V needs enough A/D resolution and higher current stability.Due to lithium battery without overcharging resisting characteristic, so adopt preliminary filling-constant current-constant-voltage method to charge, constant voltage charge time terminal voltage reaches 4.2V, charge complete flag is that charging current drops to C/10.When starting to charge to prevent overdischarge battery, electric current is excessive affects battery life, and charger should check whether cell voltage is greater than 3V before charge, if be less than, then applied after trickle is charged to 3V in advance and is carrying out quick charge.Trickle size is 1/10 of normal constant-current charging.
Be understandable that, above about specific descriptions of the present invention, the technical scheme described by the embodiment of the present invention is only not limited to for illustration of the present invention, those of ordinary skill in the art is to be understood that, still can modify to the present invention or equivalent replacement, to reach identical technique effect; Needs are used, all within protection scope of the present invention as long as meet.
