Golf laub roj teeb lifespan

Cov tsheb golf yog qhov tseem ceeb rau kev ntaus golf zoo. Lawv tseem tab tom nrhiav kev siv dav hauv cov chaw loj xws li chaw ua si lossis tsev kawm ntawv qib siab. Ib qho tseem ceeb uas ua rau lawv txaus nyiam heev yog kev siv cov roj teeb thiab hluav taws xob. Qhov no tso cai rau cov tsheb golf ua haujlwm nrog cov pa phem tsawg kawg nkaus thiab suab nrov emissions. Cov roj teeb muaj qhov tshwj xeeb lifespan thiab, yog tias dhau lawm, ua rau poob rau hauv lub tshuab ua haujlwm thiab ua rau muaj peev xwm ntawm cov dej xau thiab kev nyab xeeb xws li thermal runways thiab tawg. Yog li ntawd, cov neeg siv khoom thiab cov neeg siv khoom txhawj xeeb txog ntev npaum li cas agolf laub roj teebtuaj yeem nyob ntev kom tsis txhob muaj kev puas tsuaj thiab siv kev kho kom raug thaum xav tau.

Lo lus teb rau lo lus nug no yog hmoov tsis tsis tseem ceeb thiab nyob ntawm ntau yam, ib qho ntawm cov roj teeb chemistry. Feem ntau, lub tsheb golf laub roj teeb yuav tsum nyob nruab nrab ntawm 2-5 xyoo nyob rau hauv cov tsheb golf siv rau pej xeem thiab 6-10 xyoo hauv cov khoom ntiag tug. Rau lub neej ntev dua, cov neeg siv tuaj yeem siv cov roj teeb lithium-ion uas xav tias yuav kav ntev dua 10 xyoo thiab ncav cuag yuav luag 20 xyoo rau cov tsheb ntiag tug. Qhov ntau yam no cuam tshuam los ntawm ntau tus neeg sawv cev thiab cov xwm txheej, ua rau kev tsom xam ntau dua. Hauv tsab xov xwm no, peb yuav nkag mus tob rau hauv qhov feem ntau thiab muaj txiaj ntsig zoo hauv cov ntsiab lus ntawm lub tsheb golf, thaum muab qee cov lus pom zoo thaum ua tau.

Roj teeb chemistry

Raws li tau hais dhau los, kev xaiv ntawm roj teeb chemistry ncaj qha txiav txim siab qhov kev cia siab ntawm lub neej ntawm lub tsheb golf siv.

Lead-acid roj teeb yog cov nyiam tshaj plaws, muab lawv cov nqi qis thiab kev saib xyuas yooj yim. Txawm li cas los xij, lawv kuj muab qhov tsawg tshaj plaws kev cia siab rau lub neej, qhov nruab nrab ntawm 2-5 xyoo rau kev siv cov tsheb golf. Cov roj teeb no kuj hnyav hnyav thiab tsis zoo tagnrho rau cov tsheb me me uas yuav tsum muaj lub zog siab. Ib qho tseem yuav tsum tau saib xyuas qhov tob ntawm qhov tso tawm lossis muaj peev xwm muaj nyob hauv cov roj teeb no, yog li nws tsis pom zoo kom siv lawv qis dua 40% ntawm cov peev txheej khaws cia kom tsis txhob muaj kev puas tsuaj ntawm electrode.

Gel lead-acid golf laub roj teeb tau npaj siab los daws qhov tsis txaus ntawm cov khoom siv roj teeb golf tsheb. Hauv qhov no, cov electrolyte yog gel es tsis txhob ua kua. Qhov no txwv emissions thiab muaj peev xwm ntawm to. Nws yuav tsum muaj kev saib xyuas tsawg kawg nkaus thiab tuaj yeem ua haujlwm hauv qhov kub thiab txias, tshwj xeeb tshaj yog txias txias, uas paub tias yuav ua rau cov roj teeb degradation thiab, vim li ntawd, txo txoj sia.

Lithium-ion golf laub roj teeb yog qhov kim tshaj plaws tab sis muab lub neej ntev tshaj plaws. Feem ntau, koj tuaj yeem cia siab tias alithium-ion golf laub roj teebmus nyob txhua qhov chaw ntawm 10 mus rau 20 xyoo nyob ntawm kev siv tus cwj pwm thiab lwm yam. Qhov no feem ntau yog los ntawm electrode muaj pes tsawg leeg thiab cov khoom siv electrolyte, ua rau lub roj teeb muaj txiaj ntsig zoo thiab muaj zog dua rau kev degradation nyob rau hauv cov ntaub ntawv ntawm kev xav tau siab, them ceev ceev, thiab siv sij hawm ntev.

Cov xwm txheej ua haujlwm los xav txog

Raws li tau hais dhau los, roj teeb chemistry tsis yog qhov kev txiav txim siab nkaus xwb ntawm golf laub roj teeb lifespan. Nws yog, qhov tseeb, kev sib koom ua ke ntawm cov roj teeb chemistry thiab ntau yam kev ua haujlwm. Hauv qab no yog ib daim ntawv teev cov yam tseem ceeb tshaj plaws thiab yuav ua li cas lawv cuam tshuam nrog roj teeb chemistry.

. Overcharging thiab over-discharging: Them lossis tawm lub roj teeb dhau ntawm lub xeev ntawm kev them nqi tuaj yeem ua rau cov electrodes puas tas mus li. Kev them nyiaj ntau dhau tuaj yeem tshwm sim yog tias lub tsheb golf lub roj teeb cia ntev dhau ntawm tus nqi. Qhov no tsis yog ib qho kev txhawj xeeb loj nyob rau hauv cov ntaub ntawv ntawm lithium-ion roj teeb, qhov twg BMS feem ntau teeb tsa los txiav tawm kev them nyiaj thiab tiv thaiv cov xwm txheej zoo li no. Tshaj tawm, txawm li cas los xij, yog qhov tsis tseem ceeb los daws. Cov txheej txheem tawm yog nyob ntawm tus cwj pwm siv lub laub golf thiab lem siv. Kev txwv qhov tob ntawm qhov tso tawm yuav txwv qhov kev ncua deb ntawm lub tsheb golf tuaj yeem npog ntawm lub voj voog them. Nyob rau hauv cov ntaub ntawv no, lithium-ion golf laub roj teeb muaj qhov zoo dua vim tias lawv tuaj yeem tiv taus cov neeg caij tsheb sib sib zog nqus nrog kev cuam tshuam tsawg dua piv rau cov roj ntsha lead-acid.

. Fast charging thiab high-power demands: Fast charging and high-power demands are opposed processes in charging and discharging tab sis raug kev txom nyem los ntawm tib qhov teeb meem. Kev ceev tam sim no ntawm cov electrodes tuaj yeem ua rau cov khoom poob. Ntxiv dua thiab, cov roj teeb lithium-ion golf laub roj teeb tau zoo dua rau kev them nyiaj ceev thiab kev xav tau siab zog. Nyob rau hauv cov nqe lus ntawm daim ntawv thov thiab kev ua tau zoo, lub zog siab tuaj yeem ua tiav kev nrawm ntawm lub laub golf thiab kev ua haujlwm siab dua. Qhov no yog qhov uas lub voj voog tsav tsheb ntawm lub tsheb golf tuaj yeem cuam tshuam lub roj teeb lub neej nyob rau hauv tandem nrog kev siv. Hauv lwm lo lus, cov roj teeb ntawm lub laub golf siv ntawm qhov ceev ceev ntawm qhov chaw ntaus golf yuav dhau lub roj teeb ntawm lub tsheb golf thib ob siv ntawm qhov nrawm heev ntawm tib qhov chaw.

. Ib puag ncig tej yam kev mob: kub heev yog paub tias muaj feem xyuam rau lub roj teeb lub neej ncua. Txawm hais tias nres nyob rau hauv lub hnub los yog ua hauj lwm nyob rau hauv ze-freezing kub, qhov tshwm sim yog ib txwm muaj kev puas tsuaj rau golf laub roj teeb. Qee qhov kev daws teeb meem tau raug npaj los txo qhov cuam tshuam no. Gel Lead-Acid golf laub roj teeb yog ib qho kev daws teeb meem, raws li tau hais dhau los. Qee BMS kuj qhia txog kev them qis qis rau cov roj teeb lithium-ion kom sov lawv ua ntej C-tus nqi them siab kom txwv lithium plating.

Cov yam tseem ceeb no yuav tsum tau coj mus rau hauv tus account thaum yuav lub tsheb golf lub roj teeb. Piv txwv li, lubS38105 LiFePO4 roj teeb los ntawm ROYPOWtau tshaj tawm txog 10 xyoo dhau los ua ntej mus txog qhov kawg ntawm lub neej. Qhov no yog tus nqi nruab nrab raws li kev kuaj sim. Raws li kev siv tus cwj pwm thiab yuav ua li cas tus neeg siv tswj lub tsheb golf lub roj teeb, qhov kev cia siab rau lub voj voog lossis xyoo ntawm kev pabcuam tuaj yeem txo lossis nce siab tshaj qhov nruab nrab tus nqi qhia hauv lub tsheb golf cov ntaub ntawv.

Xaus

Hauv cov ntsiab lus, lub neej ntev ntawm lub laub golf yuav sib txawv nyob ntawm kev siv tus cwj pwm, kev ua haujlwm, thiab roj teeb chemistry. Muab thawj ob yog qhov nyuaj rau kev txheeb xyuas thiab kwv yees ua ntej, ib tus tuaj yeem tso siab rau qhov ntsuas nruab nrab raws li roj teeb chemistry. Nyob rau hauv tas li ntawd, lithium-ion golf laub roj teeb muab lub neej ntev dua tab sis tus nqi pib dua piv rau qhov qis lifespan thiab pheej yig tus nqi ntawm txhuas-acid roj teeb.
