2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:28

Cov roj teeb laptop qub yog qhov zoo ntawm Li-ion roj teeb, tsuav koj paub yuav tshuaj xyuas lawv li cas kom ntseeg tau tias lawv muaj kev nyab xeeb siv. Hauv lub roj teeb laptop zoo, muaj 6pcs ntawm 18650 lithium-ion cells. Lub xov tooj 18650 tsuas yog ib lub xov tooj ntawm tes uas muaj lub cheeb ntawm 18 hli thiab qhov siab ntawm 65 hli (kwv yees). Yog tias lub roj teeb ntawm lub laptop tsis ua haujlwm ntxiv, feem ntau tsuas yog 1 pawg ntawm cov cell uas tuag, thiab lwm 4 tseem yog qhov zoo tshaj, tab sis koj yuav tsum ntseeg tau sim lawv txhua tus kom ntseeg tau tias lawv ua haujlwm.

Txhua qhov kuv lub hlwb raug sim nrog kuv qhov chaw kuaj 18650 pom ntawm no.

Cov ntawv qhia no tseem tuaj yeem pom ntawm kuv lub vev xaib ntawm:

Kauj Ruam 1: Tshem Tawm Cov Cells

Txhawm rau tshem cov cell tawm ntawm lub roj teeb laptop, txhua yam koj yuav tsum tau ua yog tshem tawm cov yas yas. Muaj ntau txoj hauv kev uas ua haujlwm ntawm no. Nco ntsoov hnav hnab looj tes thiab tsom iav kev nyab xeeb - ib feem ntawm cov yas yas tuaj yeem ya tawm, thiab zoo nkauj heev. Cov npib tsib xee txuas cov xov tooj sib txuas ua ke yog qhov ntse heev thiab tuaj yeem txiav koj yooj yim heev, raws li kuv tau pom ntau zaus. 1 - Yog tias koj tuaj yeem ntswj cov yas yas thiab tsoo nws sib nrug, qhov ntawd yog txoj hauv kev zoo tshaj plaws los ua nws. Qhov no tsis ua haujlwm ntawm txhua lub roj teeb, thiab kuv ib txwm tsuas yog tuaj yeem ua nws ntawm 3 cell Dell pob.

2 - Tau txais ib khub ruaj khov ntawm cov xaim txiav thiab/lossis pliers thiab sim ua kom cov ces kaum tawm, lossis faib nws ntawm qhov nqaws.

3 - Ntaus pob mus rau hauv av yog txoj hauv kev zoo kom tshem cov cell tawm. Koj tuaj yeem ua rau qee lub cell puas, tab sis qhov no yog ib txoj hauv kev nrawm tshaj plaws ntawm kev tshem tawm cov cell.

Thaum cov cell raug tso tawm los ntawm cov yas yas, koj tuaj yeem ua haujlwm cais lawv mus rau hauv ib tus neeg. Lawv feem ntau yog qhov chaw sib txuas ua ke hauv 3S2P teeb tsa (rau 6 pob ntawv ntawm tes). Txiav tag nrho cov xov hlau mus rau PCB ib zaug kom tsis txhob luv. Txoj hauv kev zoo tshaj kom tau txais qhov chaw-welded npib tsib xee tawm ntawm cov cell yog ntswj lawv tawm. Lob nws nrog ib rab phom los yog cov hlais txiav, thiab yob nws tawm. Ceev faj tsis txhob ua luv Circuit Court nrog cov cuab yeej hlau - tag nrho lub roj teeb yog lub davhlau ya nyob twg tsis zoo, yog li yog qhov cua sov nyob ib puag ncig nws tau tawg, nws tuaj yeem yooj yim los tsim luv Circuit Court.

Kauj Ruam 2: Xeem Txhua Lub Cell

Txheeb Xyuas Qhov Hluav Taws Xob Thawj zaug uas kuv ua thaum txhua lub cell raug tso tawm, yog ua qhov ntsuas hluav taws xob nrawm. Yog tias cov cell muaj ntau dua 2V, tom qab ntawd lawv tuaj yeem mus ncaj rau them hauv TP4056 lub roj teeb, lossis Liitokala Lii-500 tus ntsuas. Yog tias cov cell qis dua 2V, kuv kos lawv nrog 'V', tom qab ntawd them lawv nrog TP4056 lub roj teeb.

Kev Xeem Tus Kheej

Thaum cov hlwb tau them tas, kuv cia lawv zaum 24 teev, tom qab ntawd ntsuas qhov hluav taws xob dua. Yog tias muaj cov cell tawm lawv tus kheej tsuas yog zaum ntawm qhov ntawd, lawv yuav raug tshem tawm ntawm no. Qee tus neeg yuav pom zoo ib lub lim tiam, lwm tus txog li ib hlis ua ntej kuaj lawv dua, tab sis rau kuv, 24h yog lub sijhawm zoo. Yog tias ib qho ntawm cov cell qis dua 4V ntawm qhov no, tom qab ntawd lawv tau txiav txim siab tso tus kheej tawm, thiab muab pov tseg.

Kev Ntsuas Peev Xwm

Ib lub xovtooj twg uas dhau thawj ob qhov kev sim tam sim no tau sim rau lub peev xwm hauv Liitokala Lii-500 tus ntsuas. OPUS BTC3100 yog lwm qhov kev sim ntsuas, tab sis kim dua Liitokala Lii-500, nrog rau kev ua haujlwm zoo ib yam. Lawv raug them, tom qab tso tawm thaum ntsuas lub peev xwm, thiab thaum kawg them rov qab. Kuv sau lub peev xwm ntawm cov cell, thiab tom qab ntawd txheeb lawv raws qhov muaj peev xwm. Hauv qab 1000mAh raug muab pov tseg, thiab seem tau muab cais ua 1000-1600mAh, 1600-1800mAh, 1800mAh-2000mAh, 2000-2200mAh, thiab 2200mAh+. Kuv yuav pom zoo tsuas yog siv cov cell ntau dua 1800mAh hauv cov phiaj xwm zaum kawg, thiab siv cov pov tseg cov hlwb raws li kev coj ua rau kev siv tshuaj yaj yeeb.

Qee zaum IR Test

Qhov kawg los txiav txim kev noj qab haus huv ntawm tes yog Kev tiv thaiv sab hauv. Liitokala Lii-500 ntsuas kev tiv thaiv sab hauv ntawm lub roj teeb txhua lub sijhawm koj tso nws, tab sis qee zaum kuv ua lwm qhov kev sim nrog kuv lub tsev Arduino IR Tester. Qhov kev xeem no tsis yog qhov tseem ceeb heev yog tias koj siv cov cell hauv daim ntawv thov siv hluav taws xob tsawg (<1A rau ib lub xovtooj), tabsis hauv daim ntawv thov siv zog ntau dua (1A+ kos rau ib lub xovtooj) nws tseem ceeb dua. Qhov siab dua kev tiv thaiv sab hauv ntawm koj lub cell, ntau lawv yuav sov li koj them lossis tso tawm. Cov xwm txheej hnyav tuaj yeem raug ntes tsuas yog los ntawm kev ntsuas kub thaum lub sijhawm ua haujlwm thiab kev tso tawm.

Kauj Ruam 3: Lwm Cov Lus Qhia

Thoob plaws txhua qhov kev ntsuas no (tshwj xeeb yog them thiab tshem tawm), Kuv saib xyuas qhov kub ntawm cov cell. Yog tias cov cell tau txais ntau dua 40 degrees Celsius, lawv tau cim nrog 'H', ua cua sov, thiab raug xa rov qab mus rau lub khoos phis tawj siv dua tshiab. Red Sanyo cells muaj lub siab ua kom sov.

Kuv tau rov zoo dua 2000 lub xov tooj raws li cov lus qhia no, thiab tau ua tiav ncaj ncees los txiav txim seb qhov twg yog qhov zoo. Ib lo lus ceeb toom txawm hais tias - Txhua lub hlwb uas tsis tau los ntawm cov chaw tsim khoom muaj npe - Samsung, LG, Panasonic, Sanyo - feem ntau yuav ua tsis tiav txawm tias lawv xeem tau zoo. Ntawm txhua lub xov tooj ntawm tes kuv tau siv, tsuas yog ib txhais tes ntawm cov khoom lag luam suav suav - SZN, CJ - tau ua tsis tiav.

Txoj hauv kev no tsis yog txhais tau tias yog qhov zoo tshaj plaws, ua tiav thiab raug tshaj plaws ntawm kev sim 18650 Li-ion cells, tab sis nws tsuas yog kuv coj ntawm nws.

Yog tias koj xav pom cov peev txheej ntxiv lossis lwm txoj hauv kev zoo sib xws ntawm kev sim cov cell, txheeb xyuas cov kev txuas no:
