Nyob rau hauv qhov chaw txiav txim siab xws li cov chaw hauv cov ntaub ntawv thiab kev sib txuas lus hauv lub zog ua kom muaj zog, tab sis kuj tau sim cov duab ntsuas hluav taws xob ntsuas thiab kev nyab xeeb kub dissipation. Lub ntiaj teb cov tuam txhab tau nce ntxiv lub zog ntom ntom ntawm 1KW los ntawm 2kWh rau ntawm kev xaiv cov lag luam hauv tes, thiab kev ua kom sov tshiab tsis zoo. Qhov sib txig sib txuas no yog rov ua dua cov ciaj ntawm cov chaw tsim hluav taws xob hauv pawg.
1 Qib Cell Qib Tsim Tshiab: Qhov Kev Sib Ntaus Hauv Lub Zog Hluav Taws Xob
Txoj kev ntawm "Lithium Iron phosphate + nyias nyias tsim" los ntawm cov tuam ntxhab Suav. Qee hom lag luam 3U rack mounted roj teeb siv 21700 lithium iron phosphate hlwb (uas muaj lub peev xwm nce ntawm 50% hlwb. Qhov tuab ntawm lub roj teeb ntawm lub roj teeb tau raug txo los ntawm 0.3mm rau 0.2mm rau 0.2 hli (siv siab- lub zog aluminium). Thaum ineuring lub zog compressive, tus naj npawb ntawm cov leeg hlwb tau nce los ntawm 150, l hauv 3U chaw, uas yog 30% siab dua cov tiam dhau los. Los ntawm kev siv "honeycomb kev npaj" (nrog kev sib txawv ntawm tes ntawm 0.5mm) thiab ntxig ntau lub hlwb mus rau hauv tib lub ntim, tag nrho cov peev txheej ntawm 42U khib tshaj 200kW.
Lub "ternary lithium + mos ntim tshuab" txoj kev ntawm Japanese thiab Kauslim cov lag luam. Lub roj teeb 2U khib mounted roj teeb tau pib los ntawm samsung siv cov tern mos ternary (NCM811) nrog lub zog siv hluav taws xob ntawm 300 tawm lub zog. Sab hauv cov hlwb ntawm cov hlwb tau muab tshem tawm los ntawm cov tshuab Lamination, ua kom cov khoom siv tuaj yeem ua kom cov neeg siv hluav taws xob ntxiv rau 85%. Nws lub tswv yim "lub ntsej muag pub dawb" tsim qauv: cov mos pob roj teeb cov tais diav hauv qab no, tshem tawm cov chav dej tsoos hlau thiab txo qhov hnyav los ntawm 15%. Lub zog ceev ntawm 1u module ncav 180wh / u, ua rau nws haum rau kev sib txuas lus hauv kev sib txuas lus hauv chaw nres tsheb ciav hlau.
2 Kev Ua Kom Zoo Dua: Manimeter qib Mining ntawm qhov chaw siv nyiaj ua haujlwm
Cov "Modular Stacking" cov tswvyim hauv Tebchaws Europe. Cov "lego style" roj teeb khib tsim los ntawm German chaw tsim hluav taws xob tso cai rau txhua tus qauv 1u kom zoo rau nws tus kheej thiab tshem tawm. Los ntawm cov lus qhia qhia kev tsheb ciav hlau tsim (nrog qhov yuam kev ntawm ± 0.1mm), seamless splicing nruab nrab ntawm cov qauv tau ua tiav, zam cov chaw pov tseg los ntawm kev sib txuas ntawm cable. Sab nraub qaum teb siv cov tooj liab tuav (2 hli thickness) hloov chaw ntawm 50% thiab txuag tau 30% ntawm cov khoom muaj peev xwm nce ntxiv ntawm 42U khib los ntawm 10%. Ntawm ib qho chaw ntawm cov ntaub ntawv hauv Frankfurt, cov qauv no nce lub zog cia ntom ntom los ntawm 5kWh / m ² rau 7kWh / m ².
Lub "txias thiab kub aisle sib cais" cov qauv hauv Tebchaws Meskas. Rau siab - lub zog them thiab cov teeb meem khib nyiab faib cov roj teeb hauv ob ntu: qhov sab saud (kub<35 ℃) is used for charging, the lower part (temperature<40 ℃) is used for discharging, and the middle is isolated by a heat-insulating plate (thermal conductivity of 0.02W/(m · K)). Combined with the "side in side out" airflow design, the heat dissipation efficiency is improved by 40%. At a 1C charge discharge rate, the temperature difference of the battery cell is controlled within 3 ℃, which is 60% smaller than the traditional structure, ensuring safety during high-density operation.
3 Cua sov dissipation innovation: kub tswj thev naus laus zis ntawm qhov siab ntom
Tuam Tshoj "kua txias micchanannel" thev naus laus zis. Lub roj teeb 4U rack mounted roj teeb tau los ntawm Huawei embeds microchan plab kev ncig xyuas cov roj teeb, thiab siv ib qho module kub dissipation zog ntawm 500W. Nws "precia qhov ntsuas kub kho" algorithm hloov kho tus nqi ntws raws li 30kHz), ua kom muaj qhov qis dua ntawm 2c, uas yog 10}} txias tov. Daim ntawv thov ntawm ib qho chaw zoo nkauj qhia tau hais tias cov thev naus laus zis txuas ntxiv rau lub neej roj teeb rau 8000 zaug, uas yog 25% siab dua cua txias.
Is Nrias teb qis - tus nqi daws ntawm "ntuj sov dissipation + passive txias". Rau me me thiab nruab nrab- Cov chaw tsim cua sov uas tsim los ntawm cov khoom siv xyoob ntoo " Txawm hais tias lub zog ntom yog 20% qis dua li cov kua cua txias, tus nqi yog txo los ntawm 40%. Ntawm ib qho kev sib txuas lus hauv hluav taws xob hauv New Delhi tseem ruaj khov qis dua 50℃hauv lub caij ntuj sov yuav tsum tau kev siv tau yooj yim.
Qhov siab -}} kev sib xyaw ua ke ntawm cov roj khib lithium roj teeb yog txav los ntawm "kev ua kom zoo" rau "kev ua haujlwm zoo". Nyob rau yav tom ntej, nrog rau daim ntawv thov ntawm cov khoom- Lub zog kub tsis sib xws (mim)
