I-BMS Architecture: Lapho Amaphakethe Ashibhile Ehluleka
I-BMS ingubuchopho bephakethe. Yenza lokhu kungalungile futhi akukho okunye okubalulekile.
Ubuncane bokucaciswa kokusetshenziswa kwemikhumbi ye-48V: 200A ukukhishwa okuqhubekayo (250A+ uma indawo yakho inamagquma angempela), isiqongo esingu-400A okungenani amasekhondi angu-30, ukulinganisa okusebenzayo kokuthi 1A noma ngaphezulu, ukuvala{7}}izindleko zethempele eliphansi ku-0℃. Impendulo yokuvikela idinga ukuba ngaphansi kwama-microsecond angu-100 emicimbini edlula isikhathi.
Ukulinganisa kulapho imiklamo eshibhile ishaya khona. Ukulinganisa okwenziwayo kokuthi 50-100mA akunalusizo kumaseli angu-100Ah+. Kuthatha amasonto ukulungisa noma yikuphi ukukhukhuleka okunenjongo. Sivule amaphekhi esiqhudelana naye ahlulekile futhi sathola ukuthi i-BMS isebenze ngokubhalansisa kuphela emizuzwini embalwa yokugcina yomjikelezo wokushaja ngamunye. Amaseli ahlukana phakathi kwemijikelezo engu-200-300 kwaze kwaba yilapho kushaywa umkhawulo wokuvikela owodwa. Iphakethe livala phakathi nomjikelezo. Isivakashi sibambe ongezansi ku-14th fairway. Isondlo sithola ucingo lomsakazo.
Ukulinganisa okusebenzayo kuhambisa amandla phakathi kwamaseli phakathi nokushaja nokukhipha, kugcina ukulingana ngokuqhubekayo. Umehluko wezindleko phakathi kwemiklamo ye-BMS engenzi lutho nesebenzayo isebenzisa u-$40-60 iphakethe ngalinye. Umehluko wokusebenza ngaphezu kwemijikelezo engu-3,000+ inquma ukuthi iphekhi liyahlangabezana nempilo yalo elinganiselwe.
Amandla okuxhumana abaluleke kakhulu ekusebenzeni kwemikhumbi. Uxhumano lwe-Bluetooth oluyisisekelo lunika amandla-ukuqapha kwephakethe elilodwa. Ukuhlanganiswa kwebhasi le-CAN kuvumela i-telemetry yemikhumbi emaphakathi ngamasistimu okuphatha izimoto akhona. Sinikeza kokubili ukulungiselelwa kuye ngezidingo zengqalasizinda yeklayenti.
Ukuhambisana Kwesilawuli Neshaja
I-Lithium ayiyona into eshintshile-ekushintsheni. Iphrofayili kagesi yehluke ngokwanele kangangokuthi ingqalasizinda yakho ekhona ingase idinge umsebenzi.
I-48V LiFePO4 eshajwe ngokugcwele ishaya i-58.4V. Amaseli ayishumi nesithupha ku-3.65V ngalinye. Izilawuli ezilinganiselwe ngokufaka okungu-50V max zizothosa. Abanye bavele bavale. Abanye benza umonakalo. Sikubonile sobabili. Hlola imininingwane yesilawuli sakho ngaphambi koku-oda amabhethri, hhayi ngemva kwalokho.
UCurtis 1266A-5201 uphatha i-48V lithium ngaphandle kokuguqulwa. Amayunithi e-Navitas nawo ayasebenza. Izilawuli ezindala ezinqoleni zangaphambi kuka-2015? Ibhajethi engu-$320-450 inqola ngayinye yokuthuthukiswa. Bhaka lokho kube izinombolo zakho zokuguqulwa.
Ukushintshwa kweshaja akuyona inketho. Amashaja okuhola{{1}e-asidi asebenzisa imijikelezo yokulinganisa epheka amaseli e-lithium. Ukuqedwa kwe-voltage yabo kulinganiswe ngokungalungile futhi. Amashaja e-lithium azinikele anamaphrofayili e-CC/CV afanele asebenzisa u-$280-400 wezinhlelo zokusebenza ezingu-48V.
Into eyodwa abantu abayiphuthelayo: izesekeli ze-12V. Izibani, amayunithi e-GPS, amasistimu omsindo. Izinqola eziningi zithinta i-voltage zisuka entanjeni yebhethri. Idala ukungalingani ekusetheni i-lithium. Isiguquli se-DC-se-DC sibiza u-$45-80 futhi sigcina amaseli akho angahlukani.
Inkinga yokucushwa kwe-4×12V
Sibuzwa njalo ngalokhu. Amabhethri amane e-12V ochungechungeni abiza kancane ngaphambili kunephakethe elilodwa le-48V. $1,600 uma kuqhathaniswa no-$2,000-2,200. Ukonga okusobala, akunjalo?
Cha. Ibhethri ngalinye le-12V line-BMS yalo. Abakhulumisani. Ngaphansi komthwalo, eyodwa ifinyelela imikhawulo yokuvikela kuyilapho abanye belokhu bephusha okwamanje. Amakhefu esekethe yochungechunge. Inqola ima ifile. Asikho isixwayiso, ayikho imodi exegayo, ima nje.
Noma bengahluleki ngendlela eyinhlekelele, bayakhukhuleka. Ukumelana kwangaphakathi kuyahlukahluka iyunithi neyunithi. Ngemuva kwemijikelezo engamakhulu ambalwa, ibhethri elilodwa lihlala ekushajweni okungu-95% kanti elinye lishaya ama-78%. Ishaja ibona i-aggregate voltage bese iyacisha. Amaseli ahlala engalingani. Amandla ehla ngokushesha.
Iphakethe elilodwa le-48V eline-BMS ehlanganisiwe liqeda zombili izinkinga. Amaseli ayishumi nesithupha, uhlelo olulodwa lokuphatha, ukuvikela okudidiyelwe. I-$400-600 eyengeziwe ikuthengela imijikelezo ethembekile engu-4,000 esikhundleni sezinkinga ezingu-400-600.
