Lapho bakha ibhethri le-lithium-ion, abantu abaningi bayazibuza ukuthi bangakwazi yini ukuxuba amaseli ebhethri ahlukene. Nakuba kungase kubonakale kulula, ukwenza kanjalo kungaholela ezinkingeni eziningana, ngisho nomaUhlelo Lokuphathwa Kwebhethri (i-BMS)endaweni.
Ukuqonda lezi zinselele kubalulekile kunoma ubani ofuna ukudala ibhethri eliphephile nelithembekile.
Indima ye-BMS
I-BMS iyisici esibalulekile sanoma yiliphi iphakethe lebhethri le-lithium-ion. Inhloso yayo eyinhloko ukuqapha impilo nokuphepha kwebhethri njalo.
I-BMS ilandelela ama-voltage eseli ngalinye, amazinga okushisa, kanye nokusebenza okuphelele kwephakethe lebhethri. Ivimbela noma yiliphi iseli elilodwa ekushajeni ngokweqile noma ekukhipheni ngokweqile. Lokhu kusiza ukuvimbela ukulimala kwebhethri noma ngisho nomlilo.
Uma i-BMS ihlola i-voltage yeseli, ibheka amaseli aseduze ne-voltage yawo ephezulu ngesikhathi ishaja. Uma ithola eyodwa, ingamisa ugesi wokushaja kulelo seli.
Uma iseli likhipha kakhulu, i-BMS ingayinqamula. Lokhu kuvimbela umonakalo futhi kugcine ibhethri endaweni yokusebenza ephephile. Lezi zinyathelo zokuvikela zibalulekile ekugcineni impilo yebhethri nokuphepha kwayo.
Izinkinga Ngokuxuba Amaseli
Ukusebenzisa i-BMS kunezinzuzo. Kodwa-ke, ngokuvamile akuwona umqondo omuhle ukuxuba amaseli e-lithium-ion ahlukene ephaketheni lebhethri elifanayo.
Amaseli ahlukene angaba namandla ahlukene, ukumelana kwangaphakathi, kanye namazinga okushaja/okukhipha amandla. Lokhu kungalingani kungaholela ekutheni amanye amaseli aguge ngokushesha kunamanye. Ngisho noma i-BMS isiza ekuqapheni lo mehluko, ingase ingawukhokheli ngokugcwele.
Isibonelo, uma iseli elilodwa linesimo sokushaja esiphansi (i-SOC) kunezinye, lizophuma ngokushesha. I-BMS ingase inqamule amandla okuvikela lelo seli, noma ngabe amanye amaseli asenesikhathi sokushaja. Lesi simo singaholela ekukhungathekeni futhi sinciphise ukusebenza kahle kwephakethe lebhethri, okuthinta ukusebenza.
Izingozi Zokuphepha
Ukusebenzisa amaseli angalingani nakho kubeka engcupheni yokuphepha. Ngisho noma usebenzisa i-BMS, ukusebenzisa amaseli ahlukene ndawonye kwandisa amathuba okuba nezinkinga.
Inkinga eseli elilodwa ingathinta lonke ibhethri. Lokhu kungabangela izinkinga eziyingozi, njengokubaleka kokushisa noma ama-short circuits. Nakuba i-BMS ithuthukisa ukuphepha, ayikwazi ukuqeda zonke izingozi ezihlobene nokusebenzisa amaseli angahambisani.
Kwezinye izimo, i-BMS ingavimbela ingozi esheshayo, njengomlilo. Kodwa-ke, uma kwenzeka ingozi i-BMS, ingase ingasebenzi kahle lapho othile eqala kabusha ibhethri. Lokhu kungashiya ibhethri lisengozini yezingozi zesikhathi esizayo kanye nokwehluleka kokusebenza.
Ekuphetheni, i-BMS ibalulekile ekugcineni ibhethri le-lithium-ion liphephile futhi lisebenza kahle. Kodwa-ke, kusengcono ukusebenzisa amaseli afanayo avela kumkhiqizi ofanayo kanye neqembu elifanayo. Ukuxuba amaseli ahlukene kungaholela ekungalingani, ekusebenzeni okunciphile, kanye nezingozi zokuphepha ezingaba khona. Kunoma ubani ofuna ukudala uhlelo lwebhethri oluthembekile noluphephile, ukutshala imali kumaseli afanayo kuwukuhlakanipha.
Ukusebenzisa amaseli afanayo e-lithium-ion kusiza ukusebenza kahle futhi kunciphisa izingozi. Lokhu kuqinisekisa ukuthi uzizwa uphephile ngenkathi usebenzisa ibhethri lakho.
