Okokufundisa ngezintambo okujwayelekile kanye ne-Smart 4S BMS
Thatha u-4I-S12P18650 ibhethri pack njengesibonelo
Qaphela ukuthi ungafaki i-BMS lapho usoda ikhebula.
Ⅰ.Maka ukulandelana kwemigqa yamasampula
4S BMS nge 5Intambo ye-PIN
Qaphela: Ikhebula lesampula elizenzakalelayo le4-string BMS ukucushwa kuyinto5I-PIN.
1. Maka ikhebula elimnyama njengo-B0.
2. Ikhebula lokuqala elibomvu eduze kwentambo emnyama imakwe ngokuthi B1.
... (kanye nokunye, kumakwe ngokulandelana)
5. Kuze kube yikhebuli yokugcina ebomvu, emakwe ngokuthi B4.
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 ngokuthi B2.
4. Ukuxhumana phakathi kwesigxobo esihle se-3intambo yebhethri kanye nesigxobo esinegethivu se4Intambo yebhethri imakwe ngokuthi B3.
5. I-electrode ephozithivu yentambo yebhethri yesine imakwe ngokuthi B4.
Qaphela: Ngenxa yokuthi ibhethri inenani lezintambo ezingu-4, i-B4 futhi iyinani eliphelele lephakethe lebhethri. Uma i-B4 ingesona isamba sesigaba esihle sephakethe lebhethri, ifakazela ukuthi ukuhleleka kokumaka akulungile, futhi kufanele kuhlolwe.ed 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)
5. Ikhebula B4 idayiswa endaweni yebhethri engu-B4.
Ⅳ. Ukutholwa kwe-Voltage
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 yebhethri engu-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-10mΩ kusho ukuqhutshwa; ungakwazi futhi ukulungisa i-multimeter ku-buzzer. Kuzwakala umsindo obhibhayo.
Qaphela:
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.
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.
