1. E sebelisoa e le mojule o tloaelehileng oa booster o nang le ts'ireletso ea morao-rao
Mokhoa oa ho sebelisa:

(1) Fetola potentiometer ea CV kamehla e le hore motlakase o tsoang o fihle ho boleng ba voltage boo u bo batlang
(2) Lekanya phallo ea nako e khuts'oane ea potoloho ka sebaka sa ho emisa hona joale sa 10A (hokela lipene tse peli ka kotloloho pheletsong ea tlhahiso), 'me u lokise potentiometer ea CC ho etsa hore tlhahiso ea hona joale e fihle ho boleng ba ts'ireletso bo reriloeng esale pele. . (Mohlala, boleng ba hajoale bo bonts'itsoeng ke li-meter tse ngata ke 2A, joale lebelo le phahameng le ka fihla ho 2A feela ha o sebelisa mojule, 'me letšoao le lefubelu le lefubelu le sa feleng le ntse le tsoela pele ha motlakase o fihla ho 2A, ho seng joalo letšoao le teng. tima)
Tlhokomeliso: Ha e sebelisoa sebakeng sena, hobane tlhahiso e na le khanyetso ea sampling ea hona joale ea 0.05 Ohm, ho tla ba le ho theoha ha motlakase oa 0 ~ 0.3V ka mor'a ho kopanya mojaro, e leng ntho e tloaelehileng! Phokotso ena ea motlakase ha e theohe ke mojaro oa hau, empa ho theosa ho ea ho sampling resistance.

2. Sebelisa e le tjhaja ya betri
Module ntle le ts'ebetso ea hona joale e ke keng ea sebelisoa ho tjhaja betri, hobane phapang ea khatello pakeng tsa betri le tjhaja e kholo haholo, e bakang ho tjhaja hona joale ho feteletseng, ho bakang tšenyo ea betri, kahoo betri e lokela ho sebelisoa qalong. tjhaja kamehla, ha tjhaja ho isa bohōleng bo itseng, switjha othomathike khutlela kamehla gagamalo tjhaja.

Mokhoa oa ho sebelisa:
(1) Fumana hore na motlakase o phaphametseng le ho tjhaja hona joale ha betri eo u hlokang ho e tjhaja; (Haeba parameter ea betri ea lithium e le 3.7V / 2200mAh, joale motlakase o phaphametseng oa tjhaja ke 4.2V, 'me motlakase o moholo oa ho tjhaja ke 1C, ke hore, 2200mA)
(2) Tlas'a maemo a se nang moroalo, limithara tse ngata li lekanya phallo ea motlakase, 'me potentiometer ea motlakase e sa fetoheng e lokisoa ho etsa hore motlakase o tsoang o fihle motlakaseng o phaphametseng; (Haeba u tjhaja betri ea lithium ea 3.7V, fetola motlakase o tsoang ho 4.2V)
(3) Lekanya tlhahiso ea nako e khutšoanyane ea potoloho e nang le li-multi-meter 10A hona joale setopong (hokela ka ho toba lipene tse peli ho ea qetellong ea tlhahiso), 'me u lokise potentiometer ea hona joale ho etsa hore tlhahiso ea hona joale e fihle ho boleng bo reriloeng esale pele ba ho tjhaja;
(4) Nako e sa lekanyetsoang ea ho tjhaja ke makhetlo a 0.1 ho feta hona joale; (Motlakase oa betri ts'ebetsong ea ho tjhaja o fokotseha butle-butle, butle-butle ho tloha ho tjhaja kamehla ho ea ho tjhaja kamehla, haeba motlakase o behiloe ho 1A, joale ha motlakase oa ho tjhaja o le ka tlase ho 0.1A, leseli le leputsoa le tima, botala bo botala. lebone le butswe, ka nako ena betri e tjhajilwe)
(5) Hokela betri ebe o e tjhaja.
(Mehato ea 1, 2, 3, 4 ke: pheletso ea ho kenya e hokahane le phepelo ea motlakase, 'me pheletso ea tlhahiso ha e hokahane le betri.)
3. E sebelisoa e le mochine oa mokhanni oa motlakase o matla oa LED kamehla
(1) Fumana hore na motlakase o sebetsang hona joale le o phahameng oa ho sebetsa o hloka ho khanna LED;
(2) Tlas'a maemo a se nang moroalo, li-meter tse ngata li lekanya motlakase o tsoang, 'me potentiometer ea kamehla-voltage e fetoloa ho etsa hore motlakase o tsoang o fihle ho matla a phahameng a sebetsang a LED;
(3) Sebelisa mefuta e mengata ea 10A hona joale ho lekanya phallo ea nako e khutšoanyane ea potoloho, 'me u lokise potentiometer ea hona joale ho etsa hore tlhahiso ea hona joale e fihle ho LED e reriloeng esale pele;
(4) Hokela LED 'me u leke mochine.
(Mehato ea 1, 2, le ea 3 ke: ho kenya letsoho ho hoketsoe phepelong ea motlakase, tlhahiso ha e hokahane le lebone la LED.)
