Embodiment
By describing technology contents of the present utility model, structural feature in detail, being realized object and effect, below in conjunction with execution mode and coordinate accompanying drawing to be explained in detail.
With reference to accompanying drawing 1, the utility model discloses a kind of multi-functional charging precious, comprise frame 1, on described frame 1 upper surface, be set up in parallel two lithium battery slots 2, the front end of described frame 1 is provided with bulb 3, the lower surface of frame 1 is provided with action button 4, frame 1 inside is provided with fever tablet 5, described frame 1 sidepiece is provided with power supply input adapter 6 and power supply out splice going splice, the inner side of described frame 1 is provided with and lithium battery slot 2, bulb 3, action button 4, power supply input adapter 6 and power supply out splice going splice and the connected control board of fever tablet 5, the sidepiece of described frame 1 is provided with the console switch of regulation control plate.
The charging of new structure is precious, the lithium battery of two other signals on the shelf can be connected in series, and booster tension, as the precious power supply of charging, can be given mobile phone and the charging of other media devices when needing at any time.
Can on charging treasured, increase DC voltage regulator simultaneously and increase the precious function of charging, if you think boosted voltage, that is serial connection just, but this is to be multiplied, if you want to reduce voltage, that just uses DC voltage regulator.If you expect a wide voltage, that re-uses DC voltage regulator after just its serial connection being raise and regulates.Simple any, just can be connected in series to have regulated just with an adjustable resistance.
In addition the speculum of cambered surface can be set near front end bulb 3 again, can directly utilize power supply can realize the function of flashlight.
In addition, be also provided with an infrared diode as the signal transmitting terminal of remote controller in frame 1, the treasured that makes to charge can be used as a remote controller and uses, and has increased the precious diversity of lithium electricity.
In frame 1, be provided with fever tablet 5, when needed, can pass through switch opens, realize the precious heating of whole charging, play the effect of warm hand, temperature can be controlled at 50 ° of left and right, and volume is small and exquisite, is convenient for carrying.
On the other hand, power supply access joint can be the power connection being connected with civil power, can be also USB joint, has strengthened the precious scope of application of charging.
On the other hand, in described frame 1, be also provided with warning device, warning device is connected with control board.
Warning device can detect whole control board, and when any one circuit goes wrong, alarm just occurs warning device, places circuit mistake and causes the precious damage of whole charging.
In the present embodiment, in described frame 1, be also provided with mosquito repelling lamp, described mosquito repelling lamp is connected with control board, out of doors, also can reduce bite by mosquitos by opening mosquito repelling lamp, has further promoted the precious service condition of charging.
In the present embodiment, on described control board, be provided with battery core protection module, charge management module and DC-DC boost module.
Concrete, battery core protection module is comprised of over-charge protective, Cross prevention, overheat protector three parts, and HAT2027, R5402, resettable fuse have built triple protection, and the fail safe of lithium core is strengthened greatly.
Charge management module, by having adopted CN3066, is divided into trickle charge, constant current charge, constant voltage charge and four parts of maintenance charging by charging process, makes farthest energy reserve of mobile portable power supply.
DC-DC boost module has adopted MAX1771 integrated chip, lithium core capacity can be discharged to greatest extent in safe range, reaches the object to multiple digital equipment power supply.
The charging process of New-type charge treasured is, when portable power supply has monitored charger it is charged, relay makes CN3066 start working.CN3066 is divided into four parts by whole Charge Management process, i.e. precharge, constant current charge, constant voltage charge and maintenance charging.
When CN3066 starts working, whether CN3066 can detect cell voltage lower, if so, adopts trickle charge, and a smaller constant current charges to battery, until cell voltage rises to a safety value.Afterwards, charging current keeps higher value constant, normally 10 of trickle-charge current times or larger.
The battery of 1000mAh adopts 700mA current charges, and this can be avoided the damage of large current charge to lithium core.
Under constant current charge and trickle charge state, the voltage of the continuous monitoring battery of charging management chip, the voltage when single-lithium-battery pond reaches 4.2V, and constant current charge state finishes, and proceeds to constant voltage charge state, and under this state, charging voltage is constant in 4.2V.
When the electric current of lithium core drops to after original 1/10, constant voltage charge state finishes.
Safeguarding charged state, after battery full charge, if portable power source is still inserted on charger, battery can lose electric weight due to self discharge.CN3066 is with very little electric current to the charging of lithium core or monitoring cell potential, and in order to lithium core is recharged, this state is called safeguards charged state.
In circuit, voltage, temperature, charging current and the charging interval of CN3066 meeting Real-Time Monitoring lithium core.Once the temperature of battery reaches 60 ℃, or the voltage of lithium ion battery reaches 4.2V, and constant voltage charge state stops automatically.
The foregoing is only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model specification and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
