▍ Cov Txheej Txheem Kev Sau Npe (CRS)
Ministry of Electronics & Information Technology tso tawmCov Khoom Siv Hluav Taws Xob & Cov Ntaub Ntawv Technology Cov Khoom Siv-Yuav tsum muaj rau Kev Sau Npe Nkag Nkag I- Ceeb toom rau 7thLub Cuaj Hli, 2012, thiab nws tau pib siv rau 3rdLub Kaum Hli, 2013. Cov Khoom Siv Hluav Taws Xob & Cov Ntaub Ntawv Technology Cov Khoom Yuav Tsum Tau Txais Kev Sau Npe, feem ntau hu ua BIS certification, yog hu ua CRS rau npe / ntawv pov thawj.Tag nrho cov khoom siv hluav taws xob hauv cov khoom lag luam sau npe yuav tsum tau xa tuaj rau Is Nrias teb lossis muag hauv khw Indian yuav tsum tau sau npe hauv Bureau of Indian Standards (BIS).Thaum lub Kaum Ib Hlis 2014, 15 yam khoom uas yuav tsum tau sau npe tau ntxiv.Cov pawg tshiab suav nrog: xov tooj ntawm tes, roj teeb, lub tsev txhab nyiaj fais fab, cov khoom siv hluav taws xob, LED teeb thiab cov chaw muag khoom, thiab lwm yam.
▍ BIS Battery Test Standard
Nickel system cell / roj teeb: IS 16046 (Part 1): 2018 / IEC62133-1: 2017
Lithium cell / roj teeb: IS 16046 (Part 2): 2018 / IEC62133-2: 2017
Npib cell / roj teeb muaj nyob rau hauv CRS.
▍ Vim li cas MCM?
● Peb tau tsom mus rau Indian ntawv pov thawj rau ntau tshaj 5 xyoo thiab pab cov neeg tau txais lub ntiaj teb thawj roj teeb tsab ntawv BIS.Thiab peb muaj cov kev paub dhau los thiab cov peev txheej tsim nyog hauv BIS daim ntawv pov thawj.
● Yav dhau los cov tub ceev xwm laus ntawm Bureau of Indian Standards (BIS) tau ua haujlwm ua tus kws pab tswv yim muab ntawv pov thawj, los xyuas kom meej cov ntaub ntawv ua tau zoo thiab tshem tawm qhov kev pheej hmoo ntawm kev rho npe tus lej.
● Nruab nrog muaj kev paub daws teeb meem kev txawj ntse hauv daim ntawv pov thawj, peb muab cov peev txheej hauv paus txawm hauv Is Nrias teb.MCM khaws kev sib txuas lus zoo nrog BIS cov tub ceev xwm los muab cov neeg siv khoom nrog cov kev txiav txim siab tshaj plaws, cov ntaub ntawv tshaj lij thiab cov ntaub ntawv pov thawj feem ntau thiab cov kev pabcuam.
● Peb pabcuam cov tuam txhab ua lag luam hauv ntau yam kev lag luam thiab tau txais lub koob npe nrov hauv kev ua haujlwm, uas ua rau peb muaj kev ntseeg siab thiab txhawb nqa los ntawm cov neeg siv khoom.
Hauv kev lag luam tsheb fais fab tshiab, ternary lithium roj teeb thiab lithium hlau phosphate roj teeb yeej ib txwm yog lub hom phiaj ntawm kev sib tham.Ob leeg muaj lawv qhov zoo thiab qhov tsis zoo.Lub roj teeb ternary lithium muaj lub zog siab ceev, kev ua haujlwm zoo ntawm qhov kub thiab txias, thiab kev caij nkoj siab, tab sis tus nqi kim thiab tsis ruaj khov.LFP yog pheej yig, ruaj khov, thiab muaj kev ua haujlwm kub zoo.Qhov tsis zoo yog qhov ua haujlwm tsis zoo ntawm qhov kub thiab txias thiab tsis muaj zog ceev.
Nyob rau hauv txoj kev loj hlob ntawm ob lub roj teeb, vim yog cov kev cai sib txawv thiab kev xav tau kev loj hlob, ob hom kev ua si tawm tsam ib leeg nce thiab nqis.Tab sis tsis muaj teeb meem li cas ob hom kev txhim kho, kev nyab xeeb
kev ua tau zoo yog qhov tseem ceeb.Cov roj teeb lithium-ion feem ntau yog tsim los ntawm cov khoom siv tsis zoo electrode, electrolyte thiab cov khoom zoo electrode.Cov tshuaj ua haujlwm ntawm cov khoom tsis zoo electrode graphite yog ze rau ntawm cov hlau lithium hauv lub xeev them.SEI zaj duab xis nyob rau saum npoo decomposes ntawm qhov kub thiab txias, thiab lithium ions embedded nyob rau hauv lub graphite react nrog cov electrolyte thiab cov binder polyvinylidene fluoride tso tawm ntau cua sov.Alkyl carbonate organic tov yog feem ntau siv raws li
electrolytes, uas yog flammable.Cov khoom siv hluav taws xob zoo feem ntau yog hloov pauv hlau oxide, uas muaj cov khoom muaj zog oxi dizing hauv lub xeev them, thiab yooj yim decomposed kom tso pa tawm ntawm qhov kub thiab txias.Cov pa oxygen tso tawm ua rau cov tshuaj tiv thaiv oxidation nrog cov electrolyte, thiab tom qab ntawd tso tawm ntau cov cua sov.
Yog li ntawd, los ntawm qhov pom ntawm cov khoom siv, cov roj teeb lithium-ion muaj kev pheej hmoo siab, tshwj xeeb tshaj yog thaum muaj kev tsim txom, teeb meem kev nyab xeeb yog qhov tseem ceeb.Txhawm rau simulate thiab sib piv qhov kev ua tau zoo ntawm ob lub roj teeb lithium-ion sib txawv nyob rau hauv qhov kub thiab txias, peb tau ua cov kauj ruam hauv qab no.
