48V vs 36V Golf Cart Roj teeb: Yam twg rau koj lub nkoj
Peb tau nug cov lus nug no tas li. Thiab ncaj ncees, rau 90% ntawm kev lag luam kev lag luam nug hnub no, cov lus teb yog 48V. Tsis yog vim nws yog "zoo dua" hauv qee qhov kev nkag siab, tab sis vim tias 36V tshuab tsis tau tsim los ntawm OEMs loj txij li xyoo 2008. Yog tias koj tab tom yuav tshiab, koj tab tom yuav 48V. Qhov kev txiav txim siab tiag tiag yog dab tsi tshwm sim rau koj lub nkoj 36V uas twb muaj lawm, thiab seb lithium hloov pauv puas ua rau muaj txiaj ntsig nyiaj txiag rau koj txoj haujlwm.
Uas tau hais tias, Kuv tau saib cov pab pawg muag khoom pov tseg nyiaj loj ntawm ob sab ntawm qhov sib npaug no. Kev siv nyiaj ntau dhau ntawm kev txhim kho lub peev xwm tsis tsim nyog. Underspending ntawm infrastructure thiab tom qab ntawd cuam tshuam nrog lub charger tsis ua haujlwm rau lub hlis tom qab. Sim hloov hluav taws xob hloov hluav taws xob uas raug nqi ntau dua li hloov tsheb. Qhov yuam kev yog kwv yees ib zaug koj tau pom txaus ntawm lawv.
Technical Gap hauv Plain Terms
Ib qho 48V qhov system rub tawm tam sim no kom xa tau tib lub zog. Ntawm 2,400 watts tso zis, uas yog 50 amps piv rau 66.7 amps rau 36V. Qhov txo tam sim no txhais tau tias tsis tshua muaj cua sov hauv koj cov xov hlau, cov tswj, thiab cov motors. Peb tau pom maub los heatsinks khiav 15-20℃txias rau ntawm 48V teeb nyob rau hauv tib lub load testing. Thaum tshav kub kub yog dab tsi tua hluav taws xob nyob rau lub sijhawm, yog li qhov no tseem ceeb rau lub nkoj ntev.
Lwm qhov kev ua tau zoo sib txawv yog torque. Kev khiav lub cev muaj zog ntawm qhov hluav taws xob ntau dua ua rau cov zis tawm los ntawm kwv yees li 25-33%. Ntawm cov chav kawm hauv Florida, koj yuav tsis pom. Ntawm toj roob hauv pes hauv Carolinas lossis Arizona suab puam thaj chaw nrog kev hloov pauv siab, koj cov qhua yuav xav tau.

| Ntau yam (60Ah lithium, tiaj tus) | 18-25 mi | 25-35 mi |
| Ntau yam (60Ah lithium, hilly) | 12-18 mi | 20-28 mi |
Ib yam uas ua rau tib neeg tsis meej pem: "48V" lithium tiag tiag khiav ntawm 51.2V nominal vim LiFePO4 hlwb ua haujlwm ntawm 3.2V txhua, thiab cov txheej txheem pob siv 16 hlwb hauv series. Lub rooj sib tham naming yog tshuav los ntawm cov hlau lead-acid hnub. Qhov no tseem ceeb thaum koj xaiv cov chargers thiab xyuas SOC meter compatibility. Ib lub meter calibrated rau lead-acid 48V yuav tsis nyeem kom raug ntawm lithium.
Vim Li Cas Peb Thiaj Tsis Pom Zoo 36V rau Kev Tshaj Tawm Tshiab
Peb xyoos dhau los, peb tseem yuav spec 36V lithium rau qee yam kev siv. Cov nkoj me me hauv zej zog, thaj av tiaj tus, kev txwv nyiaj txiag. Cov nqi txuag tau muaj txiaj ntsig thiab qhov sib txawv ntawm kev ua haujlwm tau txais.
Qhov kev suav ntawd tau hloov lawm. Tus nqi sib txawv ntawm 36V thiab 48V lithium pob tau nqaim mus rau thaj tsam $400-600 rau ib lub laub. Lub caij no, kev muag khoom rov qab rau 36V lub laub txuas ntxiv zuj zus raws li cov neeg yuav khoom xav txog yav tom ntej qhov teeb meem muaj. Thaum ib tus neeg thov kom peb spec lub 36V hnub no, peb thawb rov qab. Tsis yog vim tias 36V tsis ua haujlwm, tab sis vim tias qhov kev pom ntawm tsib xyoos pom zoo rau tus qauv ntawm 48V.
Qhov kev zam yog retrofit tej yaam num nyob rau hauv uas twb muaj lawm 36V fleets nrog 5+ xyoo ntawm mechanical life seem. Hloov cov tsheb mus rau 48V tsis tshua muaj kev nkag siab (ntxiv rau hauv qab no). Muab tso rau hauv 36V lithium pob thiab txuas ntxiv lub neej kev pab cuam los ntawm lwm lub xyoo caum tuaj yeem yog txoj cai hu.

Yuav Ua Li Cas Ua Tau Tsis Zoo (Los ntawm Daim Pib Txhawb Nqa thiab Rooj Sib Tham Cov Lus)
Cov ntaub ntawv lag luam tsis suav nrog hom kev ua tsis tiav. Cov no yog cov teeb meem peb pom ntau zaus hauv kev xa khoom lag luam:
Ntau 12V roj teeb configurations.
Cov neeg siv khoom sim txuag nyiaj los ntawm kev khiav peb 12V lithium packs nyob rau hauv series tsis yog ib qho kev sib xyaw 36V lossis 48V pob. Qhov no tsim cell balancing npau suav phem. Ib qho kev paub txog thev naus laus zis ntawm Cartaholics lub rooj sib tham tau muab tso rau hauv bluntly: "Koj yuav tsum tau yuav lub roj teeb 36V, tsis yog 3 × 12V roj teeb. Txhua lub voj voog tawm / them nqi yuav pom cov pob muaj peev xwm poob qis" vim qhov sib txawv ntawm tes aging hla pob. Hauv rau lub hlis, koj yuav muaj ib pob txwv rau lwm tus.
Charger incompatibility.
Lead-acid chargers yuav ua rau cov pob lithium puas. Tus nqi nkhaus tsis raug, qhov kev txiav tawm tsis raug, thiab qee cov hlau lead -acid chargers siv cov pulses sib npaug uas tuaj yeem ua rau BMS kaw. Peb tau pom daim ntawv lees paub tsis lees paub tshwj xeeb vim tias cov neeg siv khoom siv lub chargers uas twb muaj lawm es tsis txhob yuav cov lithium- tshwj xeeb units.
Cov kab tsis muaj zog.
Cov pob lithium tuaj yeem xa cov tam sim no siab dua tam sim no dua li lead-acid. Thawj cov kab hluav taws xob loj rau cov hlau lead- cov kua qaub tawm ua rau qhov hluav taws xob poob qis. Cov tsos mob zoo li lub roj teeb tsis muaj zog (kev nrawm nrawm, lub zog poob ntawm toj) tab sis lub roj teeb zoo. Cov kab yog qhov txwv. Qhov no yog tshwj xeeb tshaj yog nyob rau hauv cov laus lub laub qhov twg corrosion muaj zog conductor kuj.
Pw tsaug zog hom lockouts.
Qee chav BMS nkag mus rau hom pw tsaug zog tom qab 18-24 teev yam tsis muaj kev ua si. Kev ua haujlwm raws caij nyoog uas khaws cov tsheb thauj mus rau lub lis piam ntawm kev siv rov qab los rau cov pob khoom uas yuav tsis sawv tsis muaj ib txoj kev pib dua tshiab. Txheeb xyuas tus cwj pwm BMS thaum lub sijhawm txuas ntxiv ua ntej yuav khoom.
SOC meter tsis meej pem.
Qhov no zoo li me me kom txog rau thaum tus qhua xa ib lub laub vim tias lub meter nyeem 40% thaum muaj peev xwm tiag tiag yog 5%. Lead-acid voltage curves txawv ntawm lithium. Qhov ntsuas dag. Los yog hloov nrog lithium- ntsuas ntsuas ntsuas lossis cob qhia cov neeg ua haujlwm kom tsis quav ntsej qhov ntsuas uas twb muaj lawm.
Kev Xaiv Tus Neeg Muag Khoom Uas Tseem Ceeb
