Vim li cas thiaj muaj cov roj teeb cia hluav taws xob thiab cov roj teeb hluav taws xob, txawm tias lawv ob lub roj teeb lithium? Ntau tus neeg xav txog qhov no. Ntawm no, peb yuav piav qhia qhov txawv ntawm lawv.
Txawm hais tias ob lub zog cia roj teeb thiab cov roj teeb hluav taws xob feem ntau yog raws li lithium{0}}ion thev naus laus zis (xws li lithium hlau phosphate lossis ternary lithium), lawv cov kev siv thiab cov kev xav tau sib txawv heev, ua rau muaj qhov sib txawv tseem ceeb hauv kev tsim, kev ua haujlwm, thiab kev ua neej nyob.
Txhawm rau muab nws yooj yim, koj tuaj yeem siv qhov piv txwv:
Cov roj teeb hluav taws xob zoo li cov sprinters: qhov tseem ceeb ntawm lub zog tawg, ceev, thiab agility (siab zog, siab zog ceev). Piv txwv li, ntau lub tsheb fais fab tam sim no txhawb nqa ceev ceev; Kev them nqi qeeb yuav siv sijhawm 8 teev, thaum them nqi ceev tuaj yeem them tag nrho hauv 30 feeb xwb.
Lub zog cia roj teeb zoo ib yam li cov neeg khiav dej num marathon: ua qhov tseem ceeb ntawm kev ua siab ntev, ruaj khov, thiab tus nqi -kev ua tau zoo (ntev kev ua neej ntev, kev nyab xeeb siab, tus nqi qis). Hauv qab no, peb yuav sib piv lawv hauv kev nthuav dav thoob plaws ntau qhov ntev, raws li qhia hauv cov lus hauv qab no:

Kev tsim hluav taws xob sab (hnub ci / cua + cia), kab sib chaws (nruab nrab shaving & zaus tswj), cov neeg siv sab (chaw nyob / kev lag luam & chaw cia khoom), telecom base chaw nres tsheb thaub qab, thiab lwm yam kev siv nyob ruaj ruaj. |
|
Cov ntsiab lus tseem ceeb |
Lub zog ceev ceev (ntau tsav tsheb ntev) thiab lub zog siab ceev (ceev acceleration thiab ceev ceev). |
Lub neej voj voog ntev (them nqi txhua hnub / tso tawm ntau xyoo), kev nyab xeeb siab (kev cuam tshuam loj heev thaum tsis ua haujlwm), thiab tus nqi qis. |
|
Zog Ceev |
Siab heev. Ua ntej txo qhov hnyav thiab nce kev tsav tsheb. |
Tsawg heev. Raws li cov tshuab nyob ruaj ruaj, qhov hnyav thiab ntim yog qhov tseem ceeb tsawg; lub zog ntom ntom tuaj yeem raug txi rau kev nyab xeeb thiab kev ua neej zoo dua. |
|
Lub zog ceev |
Siab. Yuav tsum tau instant siab tam sim no tso zis rau acceleration thiab nce toj. |
Nruab nrab. Tsuas yog cov xwm txheej tswj hwm zaus, feem ntau cov ntawv thov yuav tsum muaj kev ruaj khov thiab tsis tshua muaj zog. |
|
Lub neej voj voog |
Feem ntau 1,000-3,000 cycles (nyob ntawm chemistry; NMC luv dua, LFP ntev dua). Lub neej ntawm lub tsheb yog li 8-15 xyoo. |
Very high, typically >3,500 cycles, thiab tuaj yeem tshaj 10,000 cycles. Lub zog cia tshuab yog tsim rau 15-20 xyoo. |
|
Tus nqi them / tso tawm |
Siab. Kev them nyiaj sai sai thiab siab - tus nqi tso tawm (piv txwv li, them sai sai, nrawm nrawm). |
Tsawg. Feem ntau ua haujlwm ntawm tus nqi qis thiab ruaj khov (piv txwv li, 0.5C lossis qis dua) txhawm rau txuas lub neej ntev. |
|
Nqi rhiab heev |
Siab. Cov nqi roj teeb ncaj qha cuam tshuam rau tus nqi tsheb thiab kev lag luam kev sib tw. |
Siab heev. Qhov tseem ceeb ntawm kev sib tw yog nyob rau hauv tus nqi ntawm kev khaws cia, uas yuav tsum tau them tus nqi qis tshaj plaws. |
|
Kev ua haujlwm ib puag ncig |
Complex: kev vibration, poob siab, thiab kub ntau yam (-30℃txog 50℃+). |
Relatively ruaj khov thiab tswj tau. Feem ntau ntsia hauv tsev lossis hauv cov thawv nrog cov txheej txheem thermal tswj siab heev. |
|
Battery Management System (BMS) |
Siab heev. Yuav tsum tau tiag tiag - lub sij hawm saib xyuas ntawm txhua lub xov tooj, tswj siab - tus nqi them / tso tawm, thiab ua kom muaj kev nyab xeeb thaum lub tsheb khiav lag luam. |
Tsom ntsoov rau kev sib npaug thiab kev tswj lub neej. Nrog rau ntau lub hlwb (MWh nplai), BMS yuav tsum ua kom zoo sib xws thiab txhim kho cov tswv yim them nqi / tso tawm. |
|
Mainstream Technologies |
Nickel Manganese Cobalt (NMC) roj teeb (rau siab zog ceev) thiab Lithium Iron Phosphate (LFP) roj teeb (rau kev nyab xeeb thiab kev ua neej ntev dua, nce kev lag luam sib faib). |
Feem ntau Lithium Iron Phosphate (LFP) roj teeb vim lawv qhov zoo ntawm kev nyab xeeb, kev ua neej ntev, thiab tus nqi, uas ua kom zoo nrog lub zog cia. |
Lithium ionRoj teeb pob sib dhos kabyog siv dav hauv cov cuab yeej hluav taws xob, tsev ntse, tsheb fais fab, photovoltaic zog cia, ntse teeb pom kev zoo, lub zog txawb, cov khoom siv me me thiab lub zog tshiab, thiab lwm yam.
Txawm hais tias cov roj teeb fais fab thiab lub zog cia roj teeb sib txawv hauv ntau txoj hauv kev, lub hauv paus ntsiab lus tseem ceeb ntawm cov hlwb yog tib yam: ob qho tib si muaj cov electrode zoo, tsis zoo electrode, ib qho cais, thiab electrolyte. Txawm li cas los xij, muaj qhov sib txawv tseem ceeb hauv kev tsim thiab xaiv cov khoom siv. Piv txwv li, cov roj teeb hluav taws xob xav tau siab - tus nqi them thiab tawm, yuav tsum xaiv cov khoom siv hluav taws xob zoo nrog cov khoom siv hluav taws xob zoo dua thiab qis dua D50, thaum tseem koom nrog cov khoom siv hluav taws xob xws li CNTs los txhim kho kev ua haujlwm.
Tsis tas li ntawd, kom ua tiav tus nqi siab ntawm kev tso tawm, qhov compaction ceev thiab thaj chaw ntom ntom tsis tuaj yeem siab dhau. Tam sim no, feem ntau lub zog cia hlwb yog 280Ah lossis 314Ah, thiab feem ntau yog pawg. Cov roj teeb fais fab, ntawm qhov tod tes, tuaj nyob rau hauv ob qhov txhab (cylindrical thiab prismatic) thiab stacked (prismatic).
