Isifundo sokuxhuma izintambo ze-BMS ezijwayelekile nezihlakaniphile ze-3S BMS
Thatha3S12PIsibonelo, ibhethri le-18650.
Qaphela ukuthi ungafaki i-BMS uma uhlanganisa ikhebula.
Ⅰ. Maka ukulandelana kwemigqa yokusampula
I-BMS ye-3S ene-PIN engu-4
Qaphela: Ikhebula lokulinganisa elizenzakalelayo lokucushwa kwe-BMS enezintambo ezintathu yi-4PIN.
1. Maka ikhebula elimnyama njengo-B0.
2. Intambo yokuqala ebomvu eduze kwentambo emnyama imakwe njengo-B1.
... (njalo njalo, kumakwe ngokulandelana)
4. Kuze kube yintambo ebomvu yokugcina, ephawulwe ngokuthi i-B3.
Ⅱ.Maka ukulandelana kwamaphuzu okushisela ibhethri
Thola indawo yephuzu lokushisela elihambisanayo lekhebula, qala ngokumaka indawo yephuzu elihambisanayo ebhethrini.
1. Ingqikithi yenombolo engalungile yebhethri iphawulwe ngokuthi B0.
2. Ukuxhumana phakathi kwensika eqondile yentambo yokuqala yamabhethri kanye nensika engalungile yentambo yesibili yamabhethri kumakwe njengo-B1.
3. Ukuxhumana phakathi kwensika eqondile yentambo yesibili yamabhethri kanye nensika engalungile yentambo yesithathu yamabhethri kumakwe njengo-B2.
4. I-electrode eqondile yentambo yebhethri yesi-3 imakwe njenge-B3.
Qaphela: Ngenxa yokuthi iphakethe lebhethri linezintambo ezintathu sezizonke, i-B3 nayo iyisigxobo esiphelele sephakethe lebhethri. Uma i-B3 ingeyona isigaba esiphelele sephakethe lebhethri, kufakazela ukuthi uhlelo lokumaka alulungile, futhi kumele luhlolwe futhi luphawulwe futhi.
Ⅲ.Ukushisela kanye nokuxhuma izintambo
1. I-B0 yekhebula ihlanganiswe endaweni ye-B0 yebhethri.
2. Ikhebula i-B1 lifakwe endaweni yebhethri i-B1.
3. Ikhebula le-B2 lihlanganiswe endaweni yebhethri ye-B2.
4. Ikhebula le-B3 lifakwe endaweni yebhethri ye-B3.
Ⅳ. Ukutholwa Kwe-Voltage
Kala i-voltage phakathi kwezintambo eziseduze nge-multimeter ukuqinisekisa ukuthi i-voltage efanele iqoqwe yizintambo.
Kala ukuthi i-voltage yekhebula i-B0 kuya ku-B1 ilingana ne-voltage yebhethri iphakethe i-B0 kuya ku-B1. Uma ilingana, kufakazela ukuthi iqoqo le-voltage lilungile. Uma kungenjalo, kufakazela ukuthi umugqa wokuqoqa uhlanganiswe kancane, futhi ikhebula lidinga ukushintshwa. Ngokufanisa, kala ukuthi ama-voltage ezinye izintambo aqoqwe kahle.
2. Umehluko we-voltage yentambo ngayinye akufanele udlule i-1V. Uma idlula i-1V, kusho ukuthi kunenkinga ngentambo, futhi udinga ukuphinda isinyathelo sangaphambilini ukuze kutholakale.
Ⅴ. I-BMSukutholwa kwekhwalithi
! Njalo qiniseka ukuthi i-voltage efanele iyatholakala ngaphambi kokufaka i-BMS!
Lungisa i-multimeter ibe sezingeni lokumelana kwangaphakathi bese ulinganisa ukumelana kwangaphakathi phakathi kwe-B- ne-P-. Uma ukumelana kwangaphakathi kuxhunyiwe, kufakazela ukuthi i-BMS ilungile.
Qaphela: Ungahlulela ukuhanjiswa kwe-conduction ngokubheka inani lokumelana kwangaphakathi. Inani lokumelana kwangaphakathi lingu-0Ω, okusho ukuhanjiswa kwe-conduction. Ngenxa yephutha le-multimeter, ngokuvamile, ngaphansi kuka-10mΩ kusho ukuhanjiswa kwe-conduction; ungalungisa futhi i-multimeter ibe yi-buzzer. Umsindo wokukhala ungezwakali.
Qaphela:
1. I-BMS eneswishi ethambile idinga ukunaka ukuqhutshwa kweswishi lapho iswishi ivaliwe.
2. Uma i-BMS ingasebenzi, sicela uyeke isinyathelo esilandelayo bese uxhumana nabasebenzi bokuthengisa ukuze kucutshungulwe.
Ⅵ.Xhuma umugqa wokukhipha
Ngemva kokuqinisekisa ukuthi i-BMS ijwayelekile, hlanganisa ucingo oluluhlaza okwesibhakabhaka lwe-B- ku-BMS ku-B- ephelele engemihle yebhethri. Umugqa we-P ku-BMS uhlanganiswe ne-pole engemihle yokushaja nokukhipha.
Ngemva kokushisela, hlola ukuthi i-voltage ye-BMS engaphezulu iyahambisana yini ne-voltage yebhethri.
Qaphela: Imbobo yokushaja kanye nembobo yokukhipha ye-BMS ehlukanisiwe kuhlukanisiwe, kanti umugqa we-C owengeziwe (ngokuvamile oboniswa ngophuzi) udinga ukuxhunywa epalini elingemihle leshaja; umugqa we-P uxhunyaniswe epalini elingemihle le-discharge.
Ekugcineni, faka ibhethri ebhokisini lebhethri, bese kuhlanganiswa ibhethri eliqediwe.
