Lub 72V roj teeb puas tuaj yeem mus ntawm 1500W Tsav?

Ntawm GEB, peb tsim siab - roj teeb lithium ua haujlwm rau Asmeskas thiab European ebike thiab hluav taws xob tsheb lag luam. Peb tau txais lo lus nug no ntau heev los ntawm cov neeg tsim kho kho lawv cov kev teeb tsa: Kuv puas tuaj yeem khiav lub roj teeb 72V ntawm kuv lub cev muaj zog 1500W? Cov lus teb luv luv yog yog - thiab feem ntau nws yog qhov ntse txav. Qhov kos tam sim no poob rau ib ncig ntawm 21A ntawm tag nrho 1500W load, uas ua kom sov qis thiab ua haujlwm siab. Tab sis compatibility nyob ntawm ob peb yam tseem ceeb. Tau txais lawv txoj cai, thiab koj tau txais kev ceeb toom ceev thiab lub zog. Ua rau lawv tsis raug, thiab koj yuav raug txiav tawm lossis kev puas tsuaj.

Phau ntawv qhia no taug kev los ntawm cov hauv paus, tus lej ua haujlwm tiag tiag, yam koj xav tau kom phim, thiab qhov txaus ntshai los saib. Peb tau pom ntau pua lub tsev no nyob rau hauv daim teb.

Vim li cas 72V ua haujlwm zoo nrog 1500W Motors

Fais fab sib npaug voltage zaus tam sim no: P=V × I.

Rau 1500W tso zis ntawm 72V, tam sim no yog 1500 / 72 ≈ 20.8A. Qhov ntawd yog qis. Ntawm 48V qhov system tib lub zog rub txog 31A. Cov amps siab dua txhais tau tias muaj cua sov ntau dua hauv cov xov hlau, cov khoom sib txuas, thiab lub cev muaj zog windings. Ntawm 72V lub kaw lus khiav txias dua thiab ua haujlwm zoo dua.

BLDC hub motors (feem ntau 1500W hom) tuav cov kauj ruam voltage no -zoo. Lawv qhov ntsuas KV nyob ruaj khov, yog li qhov hluav taws xob siab dua tig lub cev muaj zog sai dua. Kev ua tau zoo nyob ib puag ncig 85-90% hauv cov xwm txheej zoo.

Qhov tshwm sim: tib lub zog nominal, tab sis zoo dua tiag tiag - tus cwj pwm hauv ntiaj teb. Tsawg sag nyob rau hauv load. Tsawg zog ntawm cov khoom.

Kev Ua Tau Zoo: Yam Koj Tau Txais

Theoretical sab saum toj ceev zaum nyob ib ncig ntawm 50-70 km / h (31-43 mph) raws li lub cev muaj zog RPM scaling nrog voltage. Hauv kev xyaum, cov neeg caij tsheb feem ntau pom 45-60 km / h (28-37 mph) ntawm txoj kev tiaj tus nrog lub teeb pom kev zoo, roj teeb puv, thiab tsis muaj kev txwv.

Los ntawm forum cov ntaub ntawv thiab tsim tiag:

• Direct- tsav hub motors feem ntau ntaus 55–65 km / h hauv kev teeb tsa kom zoo (hauv av tiaj tus, 60–80kg tag nrho qhov hnyav).
• Nruab nrab- tsav lub cev muaj zog feem ntau sab saum toj qis dua, nyob ib ncig ntawm 45–55 km / h, vim yog kev tsav tsheb poob.
• Cov neeg caij tsheb hnyav dua lossis cov khoom thauj ceev 5-10 km / h.
• Me me toj los yog headwinds txiav lwm 5-15 km / h.

Kev nce toj txhim kho ntau yam - cov neeg siv qhia txog 30% kev ua haujlwm zoo dua toj piv rau 48V lossis 52V teeb tsa. Torque xav tias ntau linear vim voltage nyob ruaj khov ntev.

Nov yog lub rooj sib piv ceev rau tib lub 1500W hub lub cev muaj zog:

Cov lej no yog los ntawm cov neeg siv kev sim ntawm Endless-Sphere, Reddit, thiab YouTube khiav. Qhov ceev ceev sib txawv nrog lub log loj, lub log tsheb siab, aero luag, thiab kev tswj xyuas.

Yuav tsum -Match Components

Koj tsis tuaj yeem pauv lub roj teeb xwb. Cov khoom no yuav tsum tau ua raws li:

• Controller: Yuav tsum txhawb 72V input (feem ntau mus txog 84V ncov). A 48V-tsuas yog tus maub los yuav hlawv sai sai.
• BMS: Nruam tawm yam tsawg kawg yog 40A, zoo dua 50A +. Nws yuav tsum tau tswj cov surges luv luv rau acceleration yam tsis muaj tripping.
• Roj teeb muaj peev xwm: 20Ah yam tsawg kawg nkaus . 30-35Ah muab qhov sib npaug zoo tshaj plaws ntawm ntau yam thiab lub zog ruaj khov. Cov pob me me sag ntau dua thiab hnav sai dua nyob rau hauv siab kos.
• Txuas thiab xaim: XT90 lossis Anderson plugs. Tsawg kawg yog 10AWG hlau kom tsis txhob yaj ntawm 20A+.
• Charger: 84V cov zis sib npaug rau koj cov khoom siv hluav taws xob (feem ntau Li-ion).

Siv daim ntawv txheeb xyuas no ua ntej koj yuav:

• Controller voltage ntau npog 72V nominal / 84V max.
• BMS nruam ntsuam xyuas Ntau dua lossis sib npaug rau 40A (20% headroom tshaj qhov xav tau kos).
• Siab- paug cov hlwb (21700 hom xws li Samsung 40T tuav 35–45A ib lub xov tooj zoo dua li pheej yig 18650s).
• Lub cev haum: 72V packs hnyav dua - xyuas thav duab clearance thiab mounting.

Kev pheej hmoo thiab yuav ua li cas zam lawv

Qhov loj tshaj killer yog mismatch. Lub 48V maub los ntawm 72V tuag hauv vib nas this. Tsis muaj zog BMS mus ncig toj roob hauv pes, txiav fais fab nruab nrab - caij. Cov hlwb pheej yig sag nyuaj, poob qis thiab ua rau qis -voltage cutoff.

Lwm yam teeb meem:

• Kev kub ceev ceev tuaj yeem ua kom sov lub cev muaj zog, tab sis ntawm 72V qhov qis tam sim no pab ua kom nws txias dua li qis dua -voltage setups.
• Kev cia tsis zoo lossis huab cua txias ua rau muaj kev tiv thaiv sab hauv - lub zog poob kom txog thaum lub pob sov tuaj.
• Tshaj -volting yam tsis muaj qhov txias txias ua rau lub cev muaj zog hauv qhov xwm txheej hnyav.

Kev kho yog ncaj nraim:

• Match voltage ntsuas raws nraim.
• Xaiv cov pob lithium nrog BMS muaj zog (overcurrent, ntsuas, tiv thaiv temp).
• Ntxiv ib lub fuse ntawm lub roj teeb thiab cov tswj.
• Saib xyuas qhov voltage / tam sim no nrog LCD zaub.
• Khaws ntawm 50-60% them rau hauv nruab nrab temps.

Ua raws li txoj cai hauv zos - ntau thaj chaw hauv Teb Chaws Asmeskas thiab EU txwv ebike ceev rau 25–28 mph. Kev nrawm dua tig koj lub tsheb kauj vab mus rau lwm yam raws cai.
