Okokufundisa ngezintambo okujwayelekile kanye ne-Smart 17S BMS
Thathaawu 17 uchungechunge kanye nephakethe lebhethri le-12 parallel 18650 njengesibonelo
Qaphela ukuthi ungafaki i-BMS lapho usoda ikhebula
Ⅰ. Maka ukulandelana kwemigqa yamasampula
17 izintambo ze18Intambo ye-PIN
Qaphela: Ikhebula lesampula elizenzakalelayo le-17-string BMS ukucushwa kuyinto18I-PIN.
1. Maka ikhebula elimnyama njengo-B0.
2. Ikhebula lokuqala elibomvu eduze kwentambo emnyama imakwe ngokuthi B1
... (kanye nokunye, kumakwe ngokulandelana)
18. Kuze kube yikhebuli yokugcina ebomvu, emakwe ngokuthi B17.
Ⅱ. Maka ukuhleleka kwamaphoyinti okushisela ibhethri
Thola indawo yephoyinti lokushisela elihambisanayo lekhebula, qala umaka indawo yephuzu elihambisanayo ebhethrini
1. Ingqikithi ye-negative pole yephakethe yebhethri imakwe ngokuthi B0
2. Ukuxhumana phakathi kwepali ephozithivu yochungechunge lokuqala lwamabhethri nesigxobo esinegethivu sochungechunge lwesibili lwamabhethri kumakwe ngokuthi B1.
3. Uxhumano phakathi kwepali ephozithivu yochungechunge lwesibili lwamabhethri nesigxobo esinegethivu sochungechunge lwesithathu lwamabhethri kumakwe njengokuthi B2.
... (njalo njalo)
17. Ukuxhumana phakathi kwesigxobo esihle se-16intambo yebhethri kanye nesigxobo esinegethivu se17Intambo yebhethri imakwe ngokuthi B16.
18. I-electrode ephozithivu yeyunithi yezinhlamvu yebhethri yesi-17 imakwe njenge-B17.
Qaphela: Ngenxa yokuthi ibhethri inenani lezintambo ezingu-17, i-B17 futhi iyinani eliphelele lephakethe lebhethri. Uma i-B17 ingesona isamba sesigaba esihle sephakethe lebhethri, ifakazela ukuthi ukuhleleka kokumaka akulungile, futhi kufanele ihlolwe futhi imakwe futhi.
Ⅲ. I-soldering kanye ne-wiring
1. I-B0 yekhebula idayiswa endaweni engu-B0 yebhethri.
2. Ikhebula elithi B1 lidayiswa endaweni yebhethri engu-B1.
... (kanye nokunye, ukushisela ngokulandelana)
18. Ikhebula i-B17 idayiswa endaweni ye-B17 yebhethri.
Ⅳ. I-voltage yokutholwa
Linganisa i-voltage phakathi kwezintambo eziseduze nge-multimeter ukuze uqinisekise ukuthi i-voltage efanele iqoqwa yizintambo.
1. Linganisa ukuthi ingabe i-voltage yekhebula engu-B0 ukuya ku-B1 ilingana ne-voltage yephakethe lebhethri elithi B0 ukuya ku-B1. Uma ilingana, ifakazela ukuthi iqoqo le-voltage lilungile. Uma kungenjalo, kufakazela ukuthi umugqa wokuqoqa ushiselwe kancane, futhi ikhebula lidinga ukushiselwa kabusha. Ngokufanisa, linganisa ukuthi ama-voltage wezinye izintambo ziqoqwe ngendlela efanele yini.
2. Umehluko kagesi weyunithi yezinhlamvu ngayinye akufanele udlule u-1V. Uma idlula i-1V, kusho ukuthi kunenkinga ngezintambo, futhi udinga ukuphinda isinyathelo sangaphambilini ukuze uthole.
Ⅴ. Ukutholwa kwekhwalithi ye-BMS
! Ngaso sonke isikhathi qiniseka ukuthi kutholwa i-voltage efanele ngaphambi kokuxhuma i-BMS!
Lungisa i-multimeter ibe ileveli yokumelana kwangaphakathi futhi ulinganise ukumelana kwangaphakathi phakathi kwe-B- ne-P-. Uma ukumelana kwangaphakathi kuxhunyiwe, kufakazela ukuthi i-BMS yinhle.
Qaphela: Ungahlulela ukuqhutshwa ngokubheka inani langaphakathi lokumelana. Inani langaphakathi lokumelana ngu-0Ω, okusho ukuqhutshwa. Ngenxa yephutha le-multimeter, ngokuvamile ngaphansi kuka-10Ω kusho ukuqhuba; ungakwazi futhi ukulungisa i-multimeter ku-buzzer. Kuzwakala umsindo obhibhayo.
Isaziso:
1. I-BMS eneswishi ethambile idinga ukunaka ukusebenza kweswishi lapho iswishi ivaliwe.
2. Uma i-BMS ingasebenzi, sicela umise isinyathelo esilandelayo futhi uxhumane nabasebenzi bokuthengisa ukuze bacubungule.
Ⅵ. Xhuma umugqa wokuphumayo
Ngemva kokuqinisekisa ukuthi i-BMS ijwayelekile, thengisa intambo engu-B eluhlaza okwesibhakabhaka ku-BMS uye ku-BMS ephelele yephakethe lebhethri. I-P-line ku-BMS idayiswa esigxotsheni esinegethivu sokushaja nokukhipha.
Ngemva kokushisela, hlola ukuthi i-voltage ye-over BMS iyahambisana yini ne-voltage yebhethri.
Thola i-over-board voltage: (B-, P+) voltage = (P-, P+) voltage
Ipali ephozithivu yokushaja nokukhipha ixhunywe ngokuqondile nenani eliphelele lepali ephozithivu yephakethe lebhethri.
Qaphela: Imbobo yokushaja kanye nembobo yokukhipha impahla ye-BMS ehlukanisiwe kuyahlukaniswa, futhi ulayini u-C owengeziwe (ovame ukuboniswa ngokuphuzi) udinga ukuxhunywa esigxotsheni esinegethivu seshaja; i-P-line ixhunywe esigxotsheni esibi sokuphuma.
Ekugcineni, faka iphekhi yebhethri ngaphakathi kwebhokisi lebhethri, futhi iphakethe lebhethri eliqediwe liyahlanganiswa
