Hauv kev loj hlob ntawm cov tsheb fais fab, qhov kev thov rau cov tsheb kauj vab hluav taws xob ua haujlwm siab (E-bike) tau nce vim qhov xav tau ntev dua, kev nyab xeeb zoo dua thiab ua haujlwm zoo dua. Lub lithium-ion (Li-ion) roj teeb pob yog ib qho tseem ceeb tshaj plaws ntawm txhua lub e-tsheb tuam. Raws li cov neeg tsim khoom sab saum toj ntawmhluav taws xob tsheb kauj vab roj teeb hauv Suav teb, tsab xov xwm no delves rau hauv cov txheej txheem tsim khoom tsim thiab tsim kev txiav txim siab rau lub tsev txhim khu kev qha, kev ua haujlwm siab lithium-ion roj teeb pob rau cov tsheb kauj vab hluav taws xob.
Nkag siab txog cov hauv paus ntawm E-bike Lithium-ion Battery Packs
Cov roj teeb lithium-ion yog cov khoom siv hluav taws xob tom qab lub tsheb kauj vab hluav taws xob, muab lub zog siab ceev, lub neej ntev lub neej, thiab lub teeb hnyav piv rau cov roj teeb txhuas-acid. Cov pob no feem ntau muaj ntau lub lithium hlwb uas muaj nyob rau hauv series los yog sib npaug, uas muab qhov tsim nyog voltage thiab muaj peev xwm rau lub tsheb kauj vab lub cev muaj zog ua haujlwm tau zoo.
Kev tsim ntawm lub pob roj teeb yuav tsum ua kom muaj kev sib raug zoo nrog E-bike lub zog hluav taws xob, ua kom lub zog loj, nrawm, thiab ntau yam. Lithium hlau phosphate (LiFePO4) thiab lithium nickel manganese cobalt oxide (NMC) yog cov tshuaj lom neeg siv ntau tshaj plaws hauv E-bike roj teeb, txhua qhov muab cov txiaj ntsig tshwj xeeb ntawm kev ruaj ntseg, lifespan, thiab lub zog ceev.
E-bike lithium-ion roj teeb tsim txheej txheem
Cov txheej txheem ntawm kev tsim cov lithium-ion roj teeb pob rau E-bikes yog qhov nyuaj, suav nrog ntau theem tseem ceeb kom ntseeg tau tias kev ua tau zoo thiab kev nyab xeeb.
Kauj Ruam 1: Xaiv cov khoom nyoos thiab kev npaj ntawm tes
Cov txheej txheem tsim khoom pib nrog kev ua tib zoo xaiv cov roj teeb hlwb. E-bike lithium-ion roj teeb feem ntau siv cov cylindrical hlwb (xws li 18650 lossis 21700), prismatic, lossis lub hnab ntim, txhua tus xaiv raws li daim ntawv thov xav tau. Cov neeg tsim khoom tsim cov hlwb los ntawm cov chaw muag khoom muaj npe los xyuas kom zoo thiab sib xws. Cells raug txheeb xyuas raws li cov yam ntxwv tseem ceeb, xws li qhov hluav taws xob thiab kev tiv thaiv sab hauv, kom ntseeg tau tias muaj kev sib luag thiab kev ua haujlwm ntev.
Kauj ruam 2: Roj teeb Cell Assembly
Thaum cov hlwb tau npaj, cov txheej txheem sib dhos pib. Qhov no suav nrog kev sib txuas ntawm cov hlwb hauv series lossis sib npaug, nyob ntawm qhov xav tau qhov hluav taws xob thiab lub peev xwm ntawm E-bike system. Piv txwv li, ib lub roj teeb 48V E-tsheb tuam yuav siv tau 13-14 hlwb hauv series (3.7V txhua), thaum lub roj teeb loj dua rau kev ua haujlwm siab E-bikes yuav xav tau cov hlwb ntxiv.
Cov hlwb raug teeb tsa rau hauv kev tiv thaiv vaj tse, feem ntau ua los ntawm ABS yas ruaj khov, uas muaj kev cuam tshuam thiab tiv thaiv corrosion. Lub vaj tsev no yog tsim los tiv thaiv lub roj teeb ntawm sab nraud xws li dej, plua plav, thiab kub heev.
Kauj Ruam 3: Kev sib koom ua ke ntawm Kev Tswj Hluav Taws Xob (BMS)
Ib qho tseem ceeb ntawm cov roj teeb pob yog Lub Roj Teeb Tswj Xyuas Txheej Txheem (BMS). Lub BMS saib xyuas kev noj qab haus huv ntawm lub pob roj teeb los ntawm kev tswj cov kev them nqi thiab kev tawm mus, tiv thaiv lub hlwb los ntawm overcharging, over-discharging, thiab luv circuits. BMS tseem ua kom muaj kev nyab xeeb tag nrho ntawm lub roj teeb los ntawm kev tswj xyuas thermal tswj thiab qhov hluav taws xob sib npaug ntawm cov hlwb.
Nyob rau hauv high-end E-bike systems, advanced BMS cov kev daws teeb meem nrog CANBUS lossis UART kev sib txuas lus raws tu qauv tau koom ua ke los saib xyuas kev ua tau zoo hauv lub sijhawm tiag tiag thiab tso cai rau kev kuaj mob thiab kev ua kom zoo thaum siv.
Kauj Ruam 4: Rwb thaiv tsev thiab kev nyab xeeb nta
Lub pob roj teeb yuav tsum tau insulated kom zoo los tiv thaiv luv luv Circuit Court thiab xyuas kom muaj kev nyab xeeb thaum ua haujlwm. Cov khoom siv hluav taws xob rwb thaiv tsev tau ntxiv los tiv thaiv kev tsim hluav taws xob, thaum cov khoom siv hluav taws xob zoo thiab cov khoom sib txuas tau siv los ua kom muaj kev ruaj ntseg ntawm cov hlwb thiab lub cev muaj zog.
Cov pob khoom tsim kuj suav nrog cov yam ntxwv ntawm kev nyab xeeb sab hauv, xws li fuses thiab lub siab nyem li qub, los tiv thaiv kev pheej hmoo xws li thermal runaway lossis lwm lub cev puas tsuaj.
E-tsheb tuam roj teeb pob tsim kev xav
Thaum tsim lub lithium-ion roj teeb pob rau E-bikes, ntau yam tseem ceeb yuav tsum tau xav txog:
Voltage thiab Capacity Requirements: Thawj kauj ruam hauv tus txheej txheem tsim yog nkag siab txog qhov voltage thiab peev xwm ntawm tus qauv E-bike tshwj xeeb. Piv txwv li, 48V roj teeb pob feem ntau muab lub zog tsim nyog rau kev ua tau zoo dua E-bikes. Lub peev xwm, ntsuas hauv amp-teev (Ah), txiav txim siab npaum li cas E-bike tuaj yeem taug kev ntawm ib qho nqi, uas yog qhov tseem ceeb rau cov neeg caij tsheb thiab cov neeg caij tsheb ua si.
Roj teeb Form Factor: E-bike roj teeb pob tuaj nyob rau hauv ntau daim ntawv yam, xws li cylindrical, prismatic, los yog hnab cell. Txhua daim foos muaj txiaj ntsig tshwj xeeb. Cylindrical hlwb yog ruaj thiab siv tau, thaum lub hlwb prismatic muaj ntau qhov chaw-npaum, thiab lub hnab ntim khoom yog lub teeb yuag thiab hloov tau, zoo tagnrho rau kev cog lus lossis kev cai tsim. Daim ntawv thov cuam tshuam ncaj qha rau tag nrho cov qauv tsim ntawm lub roj teeb pob, suav nrog nws qhov loj me, cov duab, thiab kev ua haujlwm.
Kev Tswj Kev Kub Kub: Cov roj teeb lithium-ion yog qhov hloov pauv ntawm qhov kub thiab txias, thiab huab cua sov lossis txias tuaj yeem cuam tshuam rau lawv cov kev ua haujlwm thiab kev ua neej. Lub roj teeb pob tsim yuav tsum suav nrog cov kev tswj xyuas thermal zoo kom tswj tau qhov ntsuas kub kom zoo, tshwj xeeb hauv cov cheeb tsam uas muaj huab cua huab cua ntau heev. Cov phaj cua txias lossis cov ntaub qhwv thermal feem ntau yog siv los tswj cov cua sov.
Durability thiab Kev Tiv Thaiv: Sab nraud ntawm lub pob roj teeb yuav tsum ua kom ruaj khov thiab tiv taus qhov cuam tshuam, kev vibrations, thiab ib puag ncig yam xws li dej thiab plua plav. Ntau lub tuam txhab xaiv ABS yas rau nws qhov sib npaug ntawm kev ua haujlwm ntev, tus nqi, thiab kev tsim khoom yooj yim. Tsis tas li ntawd, kev tiv thaiv circuits thiab fuses yog kev koom ua ke los tiv thaiv overcurrent, overcharge, thiab luv circuits, txhim khu kev ruaj ntseg tag nrho ntawm E-bike roj teeb.
Kev Tswj Xyuas Zoo thiab Kev Xeem
Kev ua kom zoo thiab kev nyab xeeb ntawm lithium-ion roj teeb pob rau E-bikes yog qhov tseem ceeb. Cov kev tswj xyuas nruj nruj yog siv nyob rau txhua theem ntawm kev tsim khoom. Cov no suav nrog kev sim cov tib neeg lub hlwb rau qhov hluav taws xob thiab kev tiv thaiv, ua kom muaj kev sib koom ua ke hauv kev sib dhos, thiab xyuas kom meej tias Lub Roj Teeb Tswj Xyuas Txheej Txheem (BMS) ua haujlwm raug.
Kev ntsuam xyuas zaum kawg suav nrog kev ntsuas lub pob qhov kev ua tau zoo nyob rau hauv ntau yam xwm txheej, suav nrog kev them nqi thiab kev tawm mus, kev ntsuas cua sov, thiab kev ntsuas lub peev xwm. Lub hom phiaj yog los xyuas kom meej lub roj teeb pob ua tau raws li cov qauv siab tshaj plaws rau kev ua tau zoo, kev ntseeg siab, thiab kev nyab xeeb.
Trends in E-bike Battery Manufacturing
Kev lag luam roj teeb E-tsheb tuam txuas ntxiv tsim kho tshiab, nrog rau kev nce qib txhawm rau txhim kho lub zog ceev, txo qhov hnyav, thiab txhim kho kev nyab xeeb. Cov neeg tsim khoom tab tom tshawb nrhiav cov roj teeb tshiab, xws li lithium hlau phosphate (LiFePO4), uas muaj cov thermal stability zoo dua thiab lub neej ntev dua. Tsis tas li ntawd, cov tuam txhab lag luam tau txais kev coj ua kom ruaj khov, suav nrog kev siv roj teeb rov ua dua tshiab thiab cov tswv yim tsim hluav taws xob, kom txo lawv cov kev cuam tshuam ib puag ncig.
Lwm qhov tseem ceeb tshaj plaws yog kev txhim kho cov thev naus laus zis thev naus laus zis, uas txo lub sijhawm nws siv los rov them lub roj teeb E-bike. Raws li qhov kev thov rau cov tsheb kauj vab hluav taws xob loj tuaj, cov kev tsim kho tshiab no yuav ua lub luag haujlwm tseem ceeb hauv kev txhim kho tag nrho E-bike kev paub.
