Umehluko phakathi kwenkokhelo yezinyanga eziyi-14 kanye nembuyiselo yezinyanga ezingama-28 ekuguquleni kwe-lithium engu-48V ngokuvamile wehlela ezintweni ezintathu ezingakaze zivele eshidini elicacisiwe: ibanga lendawo, iminyaka yengqalasizinda yokushaja, kanye nokuthi umsebenzi wakho wokunakekela unenkontileka noma uyakhokhelwa yini.
Senze amaseli namaphekhi e-LiFePO4 kusukela ngo-2006, okwamanje athunyelwa 100+ kozakwethu be-OEM emazweni angu-80+. Lo mhlahlandlela udonsa kudatha yokufaka eqoqwe ngenethiwekhi yethu yabathengisi baseNyakatho Melika yozakwethu abasebenzayo abangu-27 ezifundazweni ezingu-16 kanye namaphrojekthi aqondile wokuhlanganisa ama-OEM. Okulandelayo kuhlanganisa izinkinga zokuhambisana, izimiso zokufaka, neziguquguqukayo ze-ROI ezinquma ukuthi iphrojekthi yokuguqula ifinyelela izinombolo zayo.
Ukuhambisana Nomkhiqizo Nonyaka Wemodeli
I-Club Car Precedent kanye namamodeli aphambili kusuka ngo-2015 kuye phambili amukela kakhulu48V LiFePO4 amaphakethengaphandle kokuguqulwa komshini. Umkhawulo ugesi: ishaja yefekthri ye-PowerDrive isebenzisa i-algorithm ye-CC/CV ene-cutoff yamanje engu-0.5A, iphansi kakhulu ukuthi i-lithium ifinyelele umthamo ogcwele. Uzobona ukushajwa okubonisiwe okungu-90% kuyilapho ushiya u-10% engasebenzi umjikelezo ngamunye. Ukulungisa kubiza u-$180-250 ngokushintsha ishaja, noma ngaphansi uma umdayisi wakho enethuluzi lokuxilonga ukuze abuyekeze i-algorithm ngokuqondile.
E-Z-Ulayini we-RXV we-GO udinga isibuyekezo sephrofayela ye-firmware ku-DELTA-Ishaja ye-Q ukuze ibone ijika lokushaja le-lithium. Lokhu kuthatha imizuzu eyi-15 ngekhebula lesixhumi esibonakalayo. Yeqe, futhi ishaja inqamuka kusenesikhathi noma icuphe ukuvikeleka kokukhokhiswa ngokweqile. Kusuka kudatha yombuzo wesiqinisekiso kubo bonke ozakwethu abangama-27 base-US nase-Canada, sibona cishe ukufaka okukodwa kokuhlanu kwe-RXV kukhiqiza ukuphinda ushaye onyakeni wokuqala lapho lesi sinyathelo sigejiwe.
I-Yamaha Drive2 iveza iwindi lamandla kagesi aqine kakhulu ku-43.2-50.4V okuzisholo wona. Iningi48V amaphakethe e-lithiumukuletha 44.4-54.6V ngokugcwele. Ngaphandle kokulungiswa kwewindi le-voltage ye-BMS, isilawuli sifunda i-overvoltage futhi siyenqaba ukuzibandakanya. Lokhu ukucushwa, hhayi ukuhambisana. Abathengisi abayibambayo ngesikhathi sokuyifaka bagwema izingcingo ezibukeka njengezinkinga zomkhiqizo kodwa akunjalo.

Iphrothokholi yokufaka
Isikhathi sokushintsha ngokomzimba sisebenza imizuzu engama-45-90 kuchwepheshe onolwazi. Izindleko zabasebenzi azishintshisani. Isezinyathelweni zokuxilonga ngaphambi nangemva kwezinyathelo zokuqinisekisa.
Ngaphambi kokuthi uthinte amatheminali ebhethri, nqamula imojuli yokunqamula i-Low Voltage yemoto. Amasistimu okuhola{{1}e-asidi ancike ku-LVD ukuze avimbele ukuchithwa okujulile; amaphakethe e-lithium anokuvikela kwangaphakathi kwe-BMS okungqubuzana namasekethe e-LVD angaphandle. Uma ithimba lethu losekelo lobuchwepheshe libuyekeza-amathikithi enyanga yokuqala, ukungqubuzana kwe-LVD kubala cishe elilodwa kwamane. Uphawu ukunqanyulwa kwamandla ngezikhathi ezithile okubukeka njengokuhluleka kwebhethri.
Ngemva kokufaka, sebenzisa ukuhlolwa kokuhamba ngebhayisikili okungu-20-80: khipha ku-20% SOC, gcwalisa kabusha ku-80%, phinda kathathu. Lokhu kuphoqa i-BMS ukuthi iqedele ukulinganisa kwamaseli. Uchungechunge oluyi-16Iphakethe le-LiFePO4ngisho neseli elilodwa{0}}lokumelana eliphezulu lisebenza ngaphansi kokusebenza kahle ngo-8-12% kuze kuqedwe ukulinganisa.
Igeji yekhebula iyimininingwane eminingi imihlahlandlela enganakwa ngayo. Isistimu engu-48V 100Ah idonsa u-60A ngokuqhubekayo no-200-300A eziqongweni zokuqalisa ikhuphuka amabanga amade. Izintambo ze-Factory 6AWG zisebenza ngokushisa ngaphansi kwamandla aphezulu okukhipha e-lithium. Izifaki ezingochwepheshe zithuthukela ku-4AWG noma ku-2AWG futhi zishintshanisa i-40A yefuse yangempela yohlobo lwe-Class T olulinganiselwe ngezici ze-lithium ze-short-circuit. Izindleko zezinto zingaphansi kuka-$40.
I-ROI: Ukuthi Kubukeka Kanjani Ukuthunyelwa Kwangempela Empeleni
Ithebula elingezansi libonisa ukusetshenziswa kwango-2023 esikunikeze endaweni yokuphumula yaseSouthern California ephethe amakalishi angu-72 e-Club Car Precedent. Sabelana ngayo ngoba ukuqagela komkhakha ngokuvamile awafaki izindleko zokushayisana.
