Kuv tau ploj mus yam tsis muaj qhov sib txawv ntawm lub rooj zaum raug tshem tawm lub hwj chim rau ntev tam sim no. PC lub zog siv hluav taws xob uas kuv tau siv los ua hluav taws xob feem ntau ntawm kuv cov phiaj xwm tau luv dua ntau zaus - Kuv tau tua 2 los ntawm kev sib tsoo - thiab xav tau kev hloov pauv, tsawg kawg rau lub zog qis. Tam sim no tam sim no pheej yig heev 5A CC Buck hloov pauv muaj uas zoo rau qee yam zoo li no. Kuv kuj tau ntxiv qhov Voltage thiab cov zaub tam sim no, hloov pauv, thiab hloov lub onboard 10K luas lauj kaub nrog cov potentiometers li niaj zaus. Kuv kuj tseem xav tau ib qho LED uas teeb thaum lub zog tso tawm luv (qhia qhov tam sim no hom), thiab ntxiv qee qhov txuas txuas txuas thiab 3mm LED los teeb rau rooj plaub.

Koj tseem tuaj yeem tshawb xyuas qhov haujlwm no ntawm kuv lub vev xaib ntawm no:

Kauj Ruam 1: Teeb Roj Teeb

18650 roj teeb tau pw nyob ib puag ncig kuv lub rooj cob qhia, thiab kuv xav tau qee yam ua nrog lawv. Kuv pom tus qauv tsim rau tus tuav 4S10P ntawm ntau yam uas kuv tau luam tawm thiab muab cov cell tso rau hauv thiab muab lawv tso nrog 2A fuses muab rau kuv 8S4P. Qhov seem ntawm qhov chaw hauv tus tuav yog siv rau CC CV pob hloov pauv thiab lwm yam khoom siv hluav taws xob. Qhov no tso cai rau qhov siab tshaj plaws tuaj yeem ua rau lub pob hloov pauv, yog li peb tau txais qhov hluav taws xob loj tshaj plaws ntawm qhov tso tawm. Qhov siab tshaj plaws yuav txo qis thiab 18650 lub hlwb tau nqus dej, tab sis kuv tsis xav tias yuav tsum tau 33V DC ntau zaus.

Kauj Ruam 2: Zaub thiab Cov Txuas Hluav Taws Xob

Cov zaub tau siv nrog 12V dhau los ntawm 7812 12V tus tswj hwm qhov hluav taws xob, uas tuaj yeem ua haujlwm txog li 35V qhov siab tshaj plaws. Ua kom tiav qhov no, Kuv ntxiv XT-60 txuas thiab qhov sib npaug sib txuas rau lub roj teeb tseem ceeb kom kuv tuaj yeem them nws. Kuv kuj tau ntxiv qee cov duab los qhia rau saum thiab hauv qab los tiv thaiv cov fuses thiab zam kev luv. Txhawm rau ua kom tiav nws, Kuv tau luam tawm kuv lub logo ntawm daim ntawv lo daim ntawv nplaum siv thiab hloov nws mus rau saum lub roj teeb.

Kuv tau siv qhov no ncaj ncees ntau zaus, feem ntau sim 18650 roj teeb. Kuv yuav nyiam nrhiav txoj hauv kev kom ntxhib thiab kho kom raug ntawm qhov hluav taws xob thiab qib tam sim no, yog li nws siv tau ntau dua. Tam sim no, nws nyuaj heev kom tau txais qhov ntsuas hluav taws xob tsis muaj qhov hloov pauv me me ntawm lub hwj chim. Kuv yuav ua ib qho zoo sib xws siv tib ntu, tab sis tsis txhob txuas nws ncaj qha rau roj teeb, siv XT-60 txuas thiab tom qab ntawd nws tuaj yeem siv nrog cov roj teeb uas kuv xav tau. Qhov ntawd yuav xav tau kev hloov pauv ib yam kom tau txais qhov siab dua, tab sis qhov ntawd nws yooj yim tsau.
