Vim li cas nws thiaj xav tau Kuv tau siv TP4056 cov qauv rau ib pliag tam sim no, thiab nyuam qhuav nyuam qhuav pom tawm tias muaj ntau qhov ntawm cov qauv cuav tawm tam sim no. Nws yog qhov nyuaj tiag tiag los nrhiav qhov tseeb TP4056 chips. Cov blog no muaj cov txheej txheem zoo rau txheeb xyuas qee cov chips thiab cov teeb meem muaj peev xwm nrog lawv. Kuv xav tau txoj hauv kev pheej yig thiab muaj txiaj ntsig los sim kuv TP4056 cov qauv kom paub tseeb tias kuv tsis ua rau muaj 18650 hlwb.
Koj tseem tuaj yeem tshawb xyuas qhov haujlwm no ntawm kuv lub vev xaib:

Kauj Ruam 1: Dummy 18650
Txhawm rau cuam tshuam txoj hauv kev tam sim no hauv 18650 kev them nqi hluav taws xob, peb xav tau ob qhov xaim xaim thiab cov khoom sib cais hauv qhov kawg ntawm tus tuav 18650, lossis ua tus dummy 18650 ntawm tes, thiab tso lwm 18650 tus tuav rau saum txhua yam. Kuv tsim 18650 xov tooj ntawm tes hauv fusion 360 (nws yooj yim heev) thiab ntxiv lub voj nyob rau sab saum toj ntawm nws kom yooj yim kom tau txais nws hauv thiab tawm ntawm txhua qhov chaw sim lossis TP4056 cov qauv. Koj tuaj yeem nrhiav cov ntawv rau nws ntawm no (tuaj sai sai).
Kauj Ruam 2: Lwm Qhov Chaw thiab Kev Sib Txuas
Tsuas yog qhov xav tau rau txoj haujlwm no yog INA219 qhov ntsuas tam sim no, tus tuav daim npav micro SD, thiab tau kawg, yog Arduino nano. Ntawm txhua qhov kawg ntawm dummy 18650, ntxig ib lub xaum npib tsib xee (siv rau qhov chaw vuam) lossis ib daim npav hnub ci. Txuas txhua tus ua ke, siv SPI rau lub micro SD daim npav thiab I2C rau INA219 tus qauv. Ib qho xaim av los ntawm Aduino yuav tsum txuas nrog rau qhov tsis zoo ntawm 18650 xov tooj kom tso cai rau INA219 los ntsuas qhov hluav taws xob ib yam. CS (Chip Xaiv) tus pin ntawm micro SD daim npav nyeem ntawv tuaj yeem txuas nrog ib qho Arduino Pin, tab sis feem ntau piv txwv siv tus pin 4, yog li kuv yuav lo nrog qhov ntawd kom tsis txhob hloov kho tus lej.
Kauj ruam 3: Code
Txhawm rau kom tau txais cov dej ntws tam sim no rau hauv 18650 hlwb, thiab qhov hluav taws xob ntawm 18650 hlwb, peb xav tau qhov ntsuas hluav taws xob thiab qhov tam sim no los ntawm INA219 tus qauv. Adafruit lub tsev qiv ntawv siv tau yooj yim heev, thiab ua haujlwm tau zoo. Raws li kev txiav cov ntaub ntawv mus rau SD card, peb tuaj yeem siv lub tsev qiv ntawv SD built-in, siv txoj hlua los tuav txhua kab ntawm cov ntaub ntawv, cais txhua tus nqi (thauj khoom voltage, tam sim no, tsheb npav voltage) los ntawm tus lej kom nws yooj yim rau ntshuam rau hauv excel thiab tsim cov duab.
Kauj Ruam 4: Them Cov Duab
Txog tam sim no, Kuv tsis tau pom ib qho ntawm TP4056 cov qauv uas kuv yuav tsum muaj teeb meem, tab sis kuv yuav sim ntsuas lawv.
