Ntau npaum li cas yog Golf Cart Battery?

Kuv tau txais tsawg kawg peb hu rau ib lub lim tiam uas pib zoo ib yam: "Ntau npaum li cas rau lub roj teeb 48V?" Kuv muab tus lej rau lawv. Ob vib nas this ntawm kev ntsiag to. "Qhov ntawd yog ntau tshaj qhov kuv pom ntawm Amazon." Nyem.

Ib hlis tom qab, tib neeg hu rov qab. Cov lus nug txawv lub sij hawm no: "Lub roj teeb kuv yuav txiav tawm. Koj puas tuaj yeem kho nws?"

Tsis yog. Koj yuav lwm tus neeg cov khoom. Kuv kho tsis tau qhov ntawd.

Lead-acid 48V systems khiav txog $1,200 txog $1,800. Lithium khiav $1,500 txog $4,000. Cov lej no yooj yim nrhiav tau nyob qhov twg. Lawv kuj tsis muaj qab hau. Lawv tsis qhia koj tias koj yuav siv li cas tshaj kaum xyoo.

Kuv tau nyob ntawm Polinovel tau rau xyoo tam sim no. Pib hauv kev txhawb nqa tech. Tam sim no tuav OEM xaj. Kuv tau pom ntau qhov kev ua tsis tiav ntau dua li kev ua tiav hauv qhov chaw no. Tsis yog vim lithium technology yog flawed. Ntau tus neeg txiav cov nqi hauv qhov chaw tsis ncaj ncees lawm.

Lithium Ion vs. Lead Acid Golf Cart Batteries

BMS Protection Cutouts -Qhov Tsis Muaj Leej Twg Qhia

Kuv yuav tsum siv sijhawm rau qhov no vim muaj coob tus neeg tsis nkag siab tias muaj dab tsi tshwm sim thaum lawv lub laub tuag ib nrab ntawm - caij.

Koj tus maub los lub cev muaj zog muaj qhov xav tau tam sim no. Cov tswj cov khoom lag luam feem ntau rub 200-400 amps. Upgraded Navitas lossis Curtis units tuaj yeem ntaus 600 amps. Thaum koj pem teb lub accelerator, lub cev muaj zog rub lub ncov tam sim no tam sim no. Yog tias koj lub roj teeb BMS raug ntsuas qis dua qhov pib no, nws ua rau muaj kev tiv thaiv. Txiav tawm. Lub laub nres.

Cov neeg ntawm Cartaholics hais tej yam zoo li "khiav zoo thaum kuv nias maj mam, txiav tawm thaum kuv pem teb." Lub roj teeb tsis tawg. Nws yog undersized. Los yog BMS specs tsis txaus. Cov tswj hwm cov khoom lag luam xav tau tsawg kawg 65Ah roj teeb ua haujlwm kom ntseeg tau. Cov kev hloov kho tshiab xav tau 105Ah yam tsawg kawg nkaus. Zoo dua 160Ah lossis siab dua. Cov roj teeb $489 "100Ah"? Lub peev xwm siv tau tiag tiag yuav yog 80Ah. BMS ncov tam sim no yuav yog 150A rau 3 vib nas this. Zoo txaus rau ntawm daim ntawv. Ib qho nyuaj acceleration thiab nws tuag.

Qhov teeb meem downhill cutout yog txawv. Ib tus neeg siv Enjoybot tau tshaj tawm rau hauv cov rooj sib tham uas nws lub laub txiav tawm txhua zaus nws nqis mus. Koj lub cev muaj zog tau rov qab- tsav los ntawm lub log ntawm qhovntsej thiaj tsis mob. Tsim rov qab -EMF uas tshaj qhov BMS overvoltage tiv thaiv qhov pib. Ib txwm series-mob lub cev tsis tau tsim nrog lithium voltage yam ntxwv hauv siab. Cov chav ua haujlwm zoo BMS muaj qhov tsim nyog overvoltage headroom. Cov pheej yig ntaus cov mob no thiab ceeb.

Tsis muaj qhov no tshwm sim ntawm ib nplooj ntawv khoom. Tsis muaj leej twg xav lees lawv BMS tej zaum yuav tsis tuav koj cov ntaub ntawv siv tshwj xeeb. Ntawm Polinovel, peb nug cov neeg siv khoom txog lawv cov qauv tswj thiab kev siv cov xwm txheej ua ntej xa khoom. BMS tsis tuaj yeem hloov kho raws li. Cov neeg muag khoom feem ntau tsis thab. Yog tias muaj qee yam tsis raug, lawv hu nws "kev siv tsis raug."

Qhov kev teeb tsa txhua tus yuav ntawm Amazon

Plaub 12V roj teeb xaim hauv series los ua 48V. Kev teeb tsa nrov tshaj plaws. Pheej yig. Zoo li yooj yim. Kev tshuaj xyuas yog ci ntsa iab.

Xyoo tas los no tus saib xyuas kev saib xyuas golf hu rau peb. Hais tias lawv cov roj teeb lithium tshiab tau tawg tawm tom qab peb lub hlis. Kuv nug seb lawv yuav dab tsi. Plaub Enjoybot 12V 100Ah units hauv series. Kuv paub qhov teeb meem ua ntej nws ua tiav cov kab lus.

Txhua 12V roj teeb muaj nws tus kheej BMS. Cov plaub BMS no tsis sib txuas lus nrog ib leeg. Thaum lub sij hawm them nyiaj, thawj tus sau rau disconnects rau kev tiv thaiv. Ua rau lub voj voog. Lwm qhov peb nres them. Thaum lub sij hawm tso tawm, thawj tus mus rau khoob disconnects. Lub peev xwm ntxiv nyob rau hauv peb qhov ua tsis tau. Ib tug neeg ntawm DIY Solar Forum muab nws zoo kawg nkaus: koj tau txais plaub BMS units ua lawv tus kheej, tsis paub txog ib leeg.

That Configuration Everyone Buys on Amazon

Khiav los ntawm ob peb lub kaum os nqi li no. Pob peev xwm poob rau 70% ntawm thawj. Qhov no tsis yog qhov teeb meem zoo ntawm tes. Qhov no yog qhov teeb meem tsim qauv. Koj txuag tau $800 los ntawm kev yuav plaub lub roj teeb sib cais es tsis txhob siv ib pob khoom. Peb lub hlis tom qab koj tau siv $ 2,000 rau kev hloov pauv.

Peb txoj hauv kev ntawm Polinovel yog ib qho -unit 48V tsim. Ib BMS tswj 16 lub hlwb hauv series. Tsis muaj teeb meem kev sib txuas lus vim tsis muaj dab tsi sib txuas lus ntawm. Qhov no tsis yog rocket science. Basic systems engineering. Nrhiav "lub laub golf lithium roj teeb" ntawm Amazon. Cov txiaj ntsig saum toj kawg nkaus yog tag nrho cov ntau- roj teeb teeb tsa. Vim lawv pheej yig. Vim lawv muag.

Cartaholics lub rooj sib tham tau txais tib cov posts txhua lub hlis. Vim li cas kuv lub roj teeb lithium tsis them tag nrho? Vim li cas kuv lub laub tuag ib nrab ntawm ib puag ncig? Yim zaug ntawm kaum, qhov no yog vim li cas.

Kaum-Xyoo Naj Npawb

Yam khoom	Lead-Acid (10 xyoo)	Lithium (10 xyoo)
Kev yuav khoom pib	$1,500	$2,500
Hloov cov voj voog	2-3 zaug	0-1 lub sijhawm
Hloov tus nqi	$3,000-$4,500	$0-$2,500
Kev tu vaj tse (watering, terminal tu)	$1,500-$3,000	~$200
Cov nqi hluav taws xob sib txawv (lead-acid 15-20% tsawg dua)	+$800	Lub hauv paus
Tag nrho	$6,800-$9,800	$2,700-$5,200

Kuv tau qhia cov lus no rau ntau tshaj ib puas tus neeg siv khoom. Txhua zaus, ib tug neeg ntsia ntawm thawj kab. "Saib, lithium raug nqi $ 1,000 ntxiv ua ntej." Kuv taw tes rau kab hauv qab. "Tam sim no saib leej twg nqis $4,000 tom qab kaum xyoo."

Lead-acid kav li ntawm 500 mus rau 1,000 cycles. Tiag -kev siv thoob ntiaj teb, qhov ntawd yog peb mus rau tsib xyoos ua ntej hloov. Lithium ua 3,000 rau 6,000 cycles. Yim mus rau kaum ob xyoos nyob rau hauv tej yam kev mob.

Thiab qhov ntawd yog ua ntej factoring hauv kev saib xyuas. Lead-acid xav tau kev kuaj xyuas dej txhua hli. Distilled dej saum-ups. Terminal corrosion ntxuav. Koj cov neeg saib xyuas siv pes tsawg teev rau qhov no txhua lub hlis? Kuv tau ua haujlwm nrog ib lub chaw ua haujlwm ib zaug ib zaug . 24 lub laub. Lawv pab neeg saib xyuas tau siv 15 teev txhua hli tsuas yog kho lub roj teeb. Tom qab hloov mus rau lithium, cov 15 teev ntawd ploj mus. Cov neeg ua haujlwm tau raug xa rov qab mus rau lwm txoj haujlwm.

Tus nqi zais hauv turf puas thiab. Lead-cov roj teeb kua qaub hnyav ib ncig 380 phaus. Lithium txiav 200-300 phaus. Cov tsheb sib zog tso cov rus ntiav ntawm cov nyom ntub. Tsawg compaction ncig cov zaub ntsuab. Nyuaj muab tus lej tseeb rau qhov no. Txhua tus thawj coj hauv chav kawm uas tau hloov pauv tau hais rau kuv.

Pricing yog ib tug mess

Lead-acid nqi yog pob tshab zoo nkauj. Trojan T-105 khiav txog $ 150 txhua. Yim ntawm lawv rau 48V system, ntxiv rau kev xa khoom thiab kev teeb tsa, koj tab tom saib $ 1,500 tag nrho. Tus nqi no tsis tau hloov ntau hauv nees nkaum xyoo. Trojan ua thawjgolf laub roj teebxyoo 1952. Ua ntej kuv txiv yug. Lawv paub tias lawv ua dab tsi.

Lithium nqi? Lub lim tiam dhau los kuv pom 48V 100Ah LiFePO4 ntawm Amazon rau $ 489. Nkoj los ntawm California. Lub npe khw yog ib txoj hlua random ntawm cov tsiaj ntawv. Tib specs los ntawm Allied tus nqi $1,800. RELiON xav tau $2,500. Peb tus nqi OEM ntawm Polinovel yog $ 600 txog $ 1,200 nyob ntawm qhov kev txiav txim ntim.

Qhov twg yog tus nqi tiag? Tag nrho lawv. Qhov txawv yog qhov koj tau txais tiag tiag.

Qhov ntawd $489 units? Kuv xav twv nyiaj nws khiav B-qib lossis C- qib cell. Cell grading tsis muaj tus qauv thoob ntiaj teb hauv kev lag luam no. Ib lub Hoobkas A- qib yuav yog lwm lub Hoobkas C- qib. Tib txoj kev txhim khu kev qha los txiav txim yog nug lawv cov hlwb uas lawv siv. Tier-ib lub tuam txhab xws li CATL, EVE Zog, BYD khiav txog 98% tus nqi tawm los. Cov chaw tsim khoom me me tuaj yeem tsoo 90-95%. EVE's LF280K tau dhau los ua tus qauv kev lag luam . 6, 000+ cycles. Zoo sib xws. Nug tus muag khoom $489 uas lawv siv. Yog tias lawv tsis tuaj yeem qhia koj, lossis muab qee qhov tsis paub meej "zoo suav suav hlwb" teb, tso tseg.

Allied thiab RELiON them nqi dab tsi lawv them ib nrab rau cov nqi hwm. Ib feem vim tias lawv siv cov hlwb zoo, tau txais ntawv pov thawj UL, muab kev pabcuam lav uas txhais tau tias qee yam. RELiON yog ib qho ntawm ob peb nrog UL2271 ntawv pov thawj. Cov qauv kev nyab xeeb tshwj xeeb rau lub teeb hluav taws xob tsheb. Rau cov neeg tsav nkoj uas saib xyuas kev lav phib xaub, daim ntawv pov thawj ntawd tsim nyog rau tus nqi sib txawv.

Polinovel txoj hauj lwm yog OEM tsum. Peb tsis ua si lub khw muag khoom markup game. Koj xav tau 50+ units, peb tuaj yeem hloov kho rau koj cov specs. Cell xaiv. Parameters ntawm BMS. Enclosure qhov ntev. Txhua tus sib tham. Chav tsev nqi khiav 30-40% hauv qab Allied. Me ntsis saum Amazon tsis muaj-npe. Koj tau txais cov khoom raug cai nrog UN38.3 ntawv pov thawj thiab kev txhawb nqa tom qab muag los ntawm peb ncaj qha.

Pricing Is a Mess
