EV Tsheb roj teeb yog dab tsi?
Core Battery Cell Cheebtsam
Txhua lub pob roj teeb muaj ntau pua / txhiab ntawm Li-ion hlwb, txhua qhov muaj plaub qhov tseem ceeb:
•Cathode: Txiav txim siab muaj peev xwm; Cov ntaub ntawv muaj xws li LFP, NCM, NCA, siv rau txhuas ntawv ci tam sim no.
•Anode: Feem ntau graphite (los yog graphite-silicon blends), coated ntawm tooj liab ntawv- tooj liab los ntawm tooj liab pas nrig / bar kom zoo conductivity.
•Electrolyte: Ib qho tshuaj nruab nrab ua kom muaj lithium ion txaus rau kev them nyiaj / tso tawm.
•Separator: Ib zaj duab xis yas ntxeem tau (PE/PP) tiv thaiv luv luv Circuit Court, feem ntau ceramic -coated.
Cov Qauv & Cov Khoom Siv Ua Haujlwm (Battery Pack Assembly)
Cells tau sib sau ua ke rau hauv modules thiab pob khoom, yuav tsum tau precision hlau stamping qhov chaw:
• Cov Neeg Sau Tam Sim No: Aluminium (cathode) thiab tooj liab (anode) foils; tooj liab los ntawm tooj liab pas nrig / bar ua kom muaj zog hloov pauv.
• Busbars & Connectors: Tooj / txhuas qhov chaw, feem ntau precision- stamped los ntawm tooj liab pas nrig / bar lossis txhuas.
• Cov ntaub thaiv npog & Cov hlua khi: Aluminium / steel qhov chaw, ntau yam ua los ntawm hlau stamping rau lub zog.
• Kev Tswj Thermal: Aluminium cua txias daim hlau thiab cov dab dej kub kom tswj tau qhov kub thiab txias.
• BMS: Saib xyuas cell voltage / kub kom nyab xeeb, ua haujlwm tau zoo.
Cov ntsiab lus tseem ceeb
Cov ntaub ntawv tseem ceeb: hlau (lithium, nickel,tooj liablos ntawm tooj liab pas nrig / bar, aluminium, steel); Tsis yog -hlau (graphite, yas, electrolytes).
Precision hlau stamping Cheebtsam (tooj liab, txhuas, hlau) yog qhov tseem ceeb rau kev nyab xeeb, siv tau EV roj teeb.
