Cov roj teeb uas muaj hluav taws xob nyob hauv tsev feem ntau raug nqi ntawm 2500 thiab 3500 yuan / kWh. Ib lub zog loj 10kWh yuav raug nqi kwv yees li 25,000 txog 35,000 yuan. Tus nqi tshwj xeeb yog cuam tshuam los ntawm hom, thev naus laus zis, muaj peev xwm, thiab teeb tsa.
Yam tseem ceeb cuam tshuam rau tus nqi
Hom roj teeb
Lithium Iron Phosphate (LiFePO₄) Roj teeb: Qhov kev xaiv tseem ceeb, muab kev nyab xeeb siab thiab kev ua neej ntev (tshaj 6000 cycles), suav txog 55% -70% ntawm tus nqi.
Ternary Lithium/Lead-Acid Batteries: Tsawg feem ntau siv hauv cov ntawv thov hauv tsev; lub qub yog kim thiab tsis ruaj khov, thaum lub tom kawg muaj luv lifespan thiab yog obsolete.
Hom thiab Technology
Cov tuam txhab ua lag luam (xws li BYD, CATL, thiab Narada) hais kom tus nqi ntawm kwv yees li 15% -30% vim lawv cov tshuab BMS siab heev thiab lub neej mus ntev.
EITAI's 11.52kWh kua- roj teeb txias yog luv nqi ntawm kwv yees li 24,700 yuan, muaj cov kua txias txias thiab lub neej voj voog siab (Ntau dua lossis sib npaug rau 8000 cycles), haum rau siab - thaj tsam kub. Thermal Management Methods
Cua -cooled system: Tus nqi qis dua, haum rau thaj tsam huab cua.
Kua-cooled system: tswj qhov kub thiab txias, txuas ntxiv roj teeb lub neej, tab sis tus nqi yog 20% -30% siab dua.
Raw Material Tus nqi hloov pauv
Xyoo 2025, tus nqi qis tshaj plaws rau lub zog cia hlwb tau mus txog 0.26 yuan / Wh (260 yuan / kWh), tab sis vim yog qhov rov qab ntawm cov nqi lithium carbonate, tus nqi nruab nrab ntawm 2026 tau rov qab mus rau 0.6-0.8 yuan / Wh.
Raws li lub Peb Hlis 2026, tus nqi sib tw yeej rau qee qhov 2-teev lub zog khaws cia tau mus txog 0.7 yuan / Wh (700 yuan / kWh).
