DIY TESLA lub zej zog cov phab ntsa tau loj hlob sai. Cov kauj ruam tseem ceeb tshaj plaws hauv kev tsim lub phab ntsa fais fab yog pab pawg ntawm cov roj teeb hauv cov pob khoom uas muaj peev xwm sib npaug. Qhov no tso cai rau teeb tsa lub roj teeb pob hauv kab thiab yooj yim ntsuas lawv rau qhov tso tawm yam tsawg kawg nkaus thiab qhov siab tshaj qhov hluav taws xob. Txhawm rau ua tiav pawg pab pawg ntawm cov roj teeb no, ib tus yuav tsum ntsuas lub peev xwm ntawm txhua lub xov tooj ntawm tes. Ntsuas lub peev xwm ntawm kaum lub roj teeb kom raug tuaj yeem yog txoj haujlwm loj thiab tsis txaus ntseeg. Qhov no yog vim li cas cov neeg txaus siab feem ntau siv kev lag luam roj teeb ntsuas zoo li ZB2L3, IMAX, Liito KALA thiab lwm yam. Txawm li cas los xij, ntawm DIY TESLA lub zej zog powerwall muaj qhov nrov heev DIY roj teeb lub peev xwm ntsuas-Brett's Arduino ASCD 18650 Ntse Charger/Discharger (https://www.vortexit.co.nz/arduino-8x-charger-discharger/). Hauv cov lus qhia no, peb yuav hloov kho lub DIY roj teeb lub peev xwm ntsuas kom lub roj teeb nyob hauv kev sim yuav hloov nws lub zog mus rau lwm lub roj teeb muaj peev xwm, yog li zam kev pov tseg lub zog thaum tshav kub kub los ntawm lub zog tiv thaiv (cov txheej txheem ib txwm ntsuas lub peev xwm roj teeb).
Kauj Ruam 1: Tsim Ib Daim Qauv ntawm Brett's DIY Battery Capacity Tester
Kuv xav kom mus ntsib Brett lub vev xaib thiab ua raws cov lus qhia https://www.vortexit.co.nz/arduino-8x-charger-discharger/. Tom qab ntawd lub tswv yim rau kev hloov kho qhov no tau qhia hauv cov phiaj xwm. Yeej, tsis txhob siv lub resistor los ntub lub ntsuas roj teeb lub zog, peb siv qhov tsawg heev Ohm resistor raws li kev tiv thaiv. Hauv peb qhov xwm txheej, peb siv 0.1 ohm 3-watt resistor. Tom qab ntawd peb tsim DC txhawb kev hloov pauv nrog kev tawm tswv yim. Muaj ntau qhov txuas txuas yuav ua li cas txhim kho Arduino tswj kev hloov pauv hloov tab sis kuv siv cov vis dis aus los ntawm Electronoobs (https://www.youtube.com/embed/nQFpVKSxGQM) uas yog kev kawm zoo heev. Tsis tas li, Electronoobs ntawm no tab tom siv Arduino yog li peb yuav siv ib feem ntawm nws cov lus tawm tswv yim voj. Tsis zoo li cov kev hloov pauv ib txwm muaj, peb yuav saib xyuas thiab sim ua kom tsis txhob tso tawm tam sim no, tsis yog qhov hluav taws xob tso tawm. Tom qab ntawd lub peev xwm loj ntawm cov roj teeb rov qab ua ke nrog lub tshuab hluav taws xob yuav ua kom tawm qhov hluav taws xob tawm raws li qhia hauv daim duab (daim duab oscilloscope). Yog tsis muaj 470uF capacitor, koj yuav tsum tau ceev faj ntawm qhov hluav taws xob qis.
Kauj Ruam 2: Lub Tshuab
Vim tias txhua txoj haujlwm tam sim no tseem tab tom txhim kho, Kuv txiav txim siab los siv cov lag luam PCB laug cam thiab txhim kho txhua yam khoom siv. Nov yog qhov kev kawm ua haujlwm rau kuv, yog li PCB tau pab kuv txhim kho kuv cov txuj ci soldering thiab kawm txhua yam ntawm analog thiab digital electronics. Kuv kuj tau xav tsis thoob nrog kev ua kom rov zoo dua qub. Qhov kuv pom yog qhov teeb tsa no tshwm sim hauv> 80% kev tsim kho tshiab rau kev tso tawm tus nqi 1 amp. Hauv cov txheej txheem, kuv qhia txhua yam khoom xav tau ntxiv rau qhov Brett tau qhia hauv nws cov duab.
Kauj Ruam 3: Arduino Code
Rau Arduino, Kuv siv Brett tus lej thiab kuv suav nrog kev ntsuas dav dav mem tes (PWM). Kuv siv lub sijhawm ntsuas kom khiav PWM ntawm 31kHz uas (hauv kev xav tab sis kuv tsis tau tshuaj xyuas) muab kev ua haujlwm zoo dua qub. Lwm cov yam ntxwv suav nrog ntsuas qhov tseeb ntawm kev tso tawm tam sim no. Koj yuav tsum tau ntsuas qhov ntsuas kom raug vim tias peb shunt resistor yog 0.1 Ohm. Hauv kev tso tawm ib feem ntawm cov cai, PWM lub luag haujlwm hloov pauv hloov kom ua kom muaj qhov ruaj khov tam sim no.
