M'malo amakono a machitidwe amagetsi, kusungira mphamvu kumakhala chinthu chofunikira kwambiri chotsimikizira kuphatikiza bwino kwa magwero amagetsi obwezerezedwanso ndikulimbitsa kukhazikika kwa gridi. Kugwiritsa ntchito kwake kumaphatikizapo kupanga magetsi, kasamalidwe ka gridi, ndi kugwiritsidwa ntchito kwa ogwiritsa ntchito, zomwe zimapangitsa kuti ikhale ukadaulo wofunikira kwambiri. Nkhaniyi ikufuna kuwunika ndikuwunikira kusanthula kwa mtengo, momwe zinthu zilili pakali pano, komanso chiyembekezo chamtsogolo cha machitidwe osungira mphamvu a batri ya lithiamu-ion.
Kuwerengera Mtengo wa Machitidwe Osungira Mphamvu:
Kapangidwe ka mtengo wa makina osungira mphamvu makamaka kamakhala ndi zinthu zisanu: ma module a batri, Ma Battery Management Systems (BMS), makontena (omwe akuphatikizapo Power Conversion Systems), ndalama zomangira ndi kukhazikitsa, ndi zina zomwe zimagwiritsidwa ntchito popanga ndi kukonza zolakwika. Potengera chitsanzo cha makina osungira mphamvu a 3MW/6.88MWh kuchokera ku fakitale ku Zhejiang Province, ma module a batri amapanga 55% ya ndalama zonse.
Kusanthula Koyerekeza kwa Ukadaulo wa Ma Battery:
Malo osungira mphamvu a lithiamu-ion akuphatikizapo ogulitsa zida zam'mwamba, ophatikiza pakati, ndi ogwiritsa ntchito kumapeto. Zipangizo zimayambira pa mabatire, Energy Management Systems (EMS), Battery Management Systems (BMS), mpaka Power Conversion Systems (PCS). Ophatikiza akuphatikizapo ophatikiza makina osungira mphamvu ndi makampani a Engineering, Procurement, and Construction (EPC). Ogwiritsa ntchito kumapeto akuphatikizapo kupanga magetsi, kasamalidwe ka gridi, kugwiritsa ntchito kwa ogwiritsa ntchito kumapeto, ndi malo olumikizirana/data.
Mtengo wa Batri ya Lithium-ion:
Mabatire a lithiamu-ion ndi omwe amagwiritsidwa ntchito kwambiri posungira mphamvu zamagetsi. Pakadali pano, msika umapereka ukadaulo wosiyanasiyana wa mabatire monga lithiamu-ion, lead-carbon, mabatire oyenda, ndi mabatire a sodium-ion, iliyonse ili ndi nthawi yoyankha yosiyana, mphamvu zotulutsa, komanso zabwino ndi zovuta zomwe zimapangidwa.
Ndalama zogulira mabatire ndi gawo lalikulu la ndalama zonse zosungira mphamvu zamagetsi zamagetsi, zomwe zimapanga mpaka 67%. Ndalama zina zimaphatikizapo ma inverter osungira mphamvu (10%), makina oyendetsera mabatire (9%), ndi makina oyendetsera mphamvu (2%). M'malo mwa ndalama za batire ya lithiamu-ion, zinthu za cathode zimakhala ndi gawo lalikulu kwambiri pafupifupi 40%, kutsatiridwa ndi zinthu za anode (19%), electrolyte (11%), ndi zolekanitsa (8%).
Zochitika ndi Mavuto Amakono:
Mtengo wa mabatire osungira mphamvu wakhala ukutsika chifukwa cha kutsika kwa mitengo ya lithiamu carbonate kuyambira 2023. Kugwiritsa ntchito mabatire a lithiamu iron phosphate pamsika wosungira mphamvu m'dziko muno kwawonjezera kuchepetsa ndalama. Zipangizo zosiyanasiyana monga cathode ndi anode materials, separator, electrolyte, current collector, structural components, ndi zina zawona kusintha kwa mitengo chifukwa cha zinthu izi.
Komabe, msika wa mabatire osungira mphamvu wasintha kuchoka pa kusowa kwa mphamvu kupita ku kuchuluka kwa magetsi, zomwe zikuwonjezera mpikisano. Olowa nawo ochokera m'magawo osiyanasiyana, kuphatikiza opanga mabatire amagetsi, makampani opanga ma photovoltaic, makampani atsopano osungira mabatire amagetsi, ndi akatswiri odziwika bwino pantchito, alowa nawo mpikisano. Kuchuluka kumeneku, pamodzi ndi kukulirakulira kwa mphamvu za osewera omwe alipo, kumabweretsa chiopsezo chokonzanso msika.
Mapeto:
Ngakhale kuti pali mavuto ambiri okhudzana ndi kuchuluka kwa magetsi komanso mpikisano waukulu, msika wosungira magetsi ukupitiliza kukula mofulumira. Poganiziridwa kuti ndi dera lomwe lingathe kugulitsidwa ndalama zokwana madola trilioni, umapereka mwayi waukulu wokulirapo, makamaka pakati pa kulimbikitsa kosalekeza kwa mfundo za mphamvu zongowonjezwdwanso komanso magawo olimba a mafakitale ndi amalonda aku China. Komabe, mu gawo ili la kuchuluka kwa magetsi komanso mpikisano woopsa, makasitomala atsopano adzafuna miyezo yapamwamba yamagetsi. Oyamba kumene ayenera kukhazikitsa zopinga zaukadaulo ndikukulitsa luso lawo kuti apite patsogolo m'malo osinthika awa.
Mwachidule, msika waku China wa mabatire a lithiamu-ion ndi osungira mphamvu uli ndi zovuta zambiri komanso mwayi wochuluka. Kumvetsetsa kusanthula mtengo, ukadaulo, ndi momwe msika ukugwirira ntchito ndikofunikira kwambiri kwa mabizinesi omwe akuyesetsa kukhala ndi mwayi waukulu mumakampani omwe akusintha mwachangu.
