Otsatira oyambilira amakumana ndi zolipirira zoyambira 100-200 zomwe nthawi zambiri zimachotsa zabwino zamtengo wapatali.
Kodi ndiyenera kukulitsa kuchuluka kwa batire yanga kuti ndiwononge kuwonongeka?
Makina ambiri oyikapo amakula mochulukira ndi 15-25% kuti ateteze ku kuwonongeka, pomwe masamba ang'onoang'ono nthawi zina amapitilira 30-35%. Kuchulukira kokwanira kumatengera zinthu zingapo: kuchulukira kwapang'onopang'ono (kuzungulira kolemetsa kwa tsiku ndi tsiku kumafuna chitetezo chochulukirapo kuposa kuzungulira kwa kuwala kwa sabata), kuya kwapang'onopang'ono (kupalasa njinga 20-80% SOC kumatalikitsa moyo kuyerekeza ndi 0-100% kupalasa njinga), kasamalidwe ka kutentha kogwira ntchito, ndi kuyerekezera mtengo wosinthira. Machitidwe ogwiritsira ntchito makina ogwiritsira ntchito makina owonongeka amatha kuchepetsa kuchulukitsitsa mpaka 10-15% pamene akusunga zolinga zogwirira ntchito, koma machitidwe ochiritsira ayenera kukhala ndi bajeti ya 20-25% yowonjezera ntchito zazaka 10.
Kodi cholakwika chachikulu ndi chiyani chomwe opanga madalaivala amasankha posankha ukadaulo wa batri?
Kusankha chemistry ya batri yotengera mphamvu ya kachulukidwe ka mphamvu m'malo mofananiza zinthu zama electrochemical ndi zomwe zimafunikira pakugwirira ntchito kumayambitsa kulephera kwa polojekiti. Pafupifupi 19 % ya mapulojekiti amapeza phindu lochepa chifukwa cha zovuta zaukadaulo komanso kutha kwa nthawi kosakonzekera, nthawi zambiri kuchokera kuzinthu zosagwirizana-monga kugwiritsa ntchito lithiamu-ion kwa maola 10-maola 10 pomwe mabatire othamanga amapambana, kapena kusankha mabatire oyendera kuti aziwongolera pafupipafupi zomwe zimafunikira kuyankha kwa mphindi zochepa. Cholakwika chachiwiri chachikulu ndikuchepetsa zofunikira pakuwongolera kutentha: Ntchito m'malo otentha popanda kuzizira kokwanira zimawona kuwonongeka komwe kumawononga chuma. Sankhani ukadaulo wanthawi yayitali yomwe mukufuna, maulendo apanjinga, komanso momwe chilengedwe chimakhalira, osati za "batire yabwino kwambiri".
Kodi mabatire achiwiri-amoyo a EV ndi odalirika kuti asungidwe pa gridi?
Yachiwiri-Mabatire a EV amoyo akupuma pa 70-80% mphamvu yake yoyamba ikugwirabe ntchito posungira osasunthika popanda kukhwimitsa kwambiri. Porsche's 5-megawatts 5,400 sekondi-ma module a Taycan amoyo akuwonetsa kugwira ntchito ndi 10+ zaka zomwe zikuyembekezeredwa moyo. Msika wachiwiri-akuyembekezeka kukula kuchokera pa 25-30 gigawatt-hours mu 2025 kufika pa 330-350 GWh mu 2030. Komabe, zovuta zikuphatikizapo kusanja ndi kuyika zilembo, maunyolo osakhwima, ndi data yochepa yanthawi yayitali. Mabatire amoyo wachiwiri amagwira bwino ntchito ngati kumetedwa kwambiri kwamalonda kapena ma microgrid ammudzi pomwe 30-50% yowongola ndalama imatsimikizira kuperewera kwa mphamvu komanso chiwopsezo chakuwonongeka kofulumira kuchokera ku mbiri yakale yosadziwika.
Kusankha Njira Yanu Yopita Patsogolo
Kusankha kwamagetsi osungira mphamvu za batri kumatengera kufananiza magawo atatu: zofunikira pakugwiritsa ntchito, kulekerera zoopsa, ndi zovuta zachuma. Palibe umisiri umodzi womwe umakhala wamphamvu pazochitika zonse-zilizonse zimakhala ndi maubwino ake pakagwiritsidwe ntchito.
Kwaufupi-kuwongolera pafupipafupi komanso kumeta kwambiri (osachepera maola 4):Lithium-ion LFP imapereka mphamvu zokwanira zogwirira ntchito bwino, nthawi yoyankhira, ndi moyo wanthawi zonse, ndi njira zogulitsira zomwe zimachepetsa chiwopsezo cha polojekiti ngakhale kukwera mtengo.
Kwa-nthawi yayitali yosinthiranso (6+ maola):Mabatire akuyenda amakhala ndi moyo wabwino-achuma mukakhala ndi malo ndipo mutha kuvomereza kugwiritsa ntchito mphamvu zochepa, ngakhale lithiamu{1}}ion imakhalabe yopambana mpaka 2025 chifukwa cha zabwino zake zopanga.
Zachitetezo-zoyika zofunika kwambiri:Mabatire oyenda amachotsa chiwopsezo chothawira kwathunthu, pomwe LFP imapereka chitetezo chovomerezeka pamtengo wotsika. Pewani NMC pakayaka moto{1}}malo omwe simukuwotcha.
Pamtengo-mphamvu zosunga zobwezeretsera zochepa:Lead{{0}acid kapena second-life lithium-ion imachepetsa ndalama zotsogola pamene kupalasa njinga sikuchitika kawirikawiri, kuvomereza kuti moyo ukhale waufupi ngati malonda a zachuma-kuchotsedwa.
Malo osungira mabatire akupitiliza kusinthika mwachangu. Ukadaulo womwe ukuwoneka kuti ukuyenda bwino mu 2025-sodium-ion, iron-mpweya, wolimba-ikhoza kusinthanso chuma pofika chaka cha 2030. Komabe mfundo zazikuluzikulu za ma electrochemical sizisintha: Fananizani chemistry ndi kayendesedwe ka njinga, samalani ndi kutentha, ndi mapangidwe kuti awonongeke kuyambira tsiku loyamba.
19% ya ma projekiti omwe amakumana ndi zolephera zaukadaulo ndikuchepetsa kubweza amagawana ulusi womwewo: Adakonzekeletsa magawo olakwika. Kachulukidwe ka mphamvu kamakhala kocheperako poyerekeza ndi zomwe zimafunikira pakutha. Mtengo pa kWh ndi wocheperapo kuposa mtengo wonse wa umwini kuphatikiza kuwononga, kukonza, ndi kubweza. Zatsopano zaukadaulo zimafunikira zochepa kuposa kukhwima kwa chain chain komanso kupezeka kwandalama.
Sankhani batire lomwe likugwirizana ndi momwe mumagwirira ntchito, osati lomwe limapambana pamatchulidwe amodzi. Njira yabwino kwambiri yosungira mphamvu ya batri ndi yomwe imapereka magwiridwe antchito odalirika pamtengo wovomerezeka pakugwiritsa ntchito kwanu pa moyo wake wonse.
Zofunika Kwambiri
Zofunikira pa nthawi yakugwiritsa ntchito (osachepera maola 2, 2-maola 6, 6+ maola) zitsimikizirani kuti ndi batire liti lomwe limakupatsani mwayi wopeza bwino zachuma osati kutsimikizika kwa magwiridwe antchito amtundu uliwonse.
Pafupifupi 19% ya mapulojekiti a batri amachepetsa kubweza kuchokera ku zovuta zaukadaulo, makamaka kuchokera kuukadaulo wosagwirizana kupita ku zofuna zamapulogalamu.
Lithium-ion (LFP) ili ndi gawo la 88.6% pamsika mu 2024 chifukwa cha kuchuluka kwa zopanga komanso kupezeka kwandalama, osati luso lapadziko lonse lapansi
Mabatire akuyenda amatha kupeza $20-25/kWh kwa nthawi yayitali-kusungirako kwanthawi yayitali poyerekeza ndi lithium-ion's $100-175, koma kwa maora 6+ okhawo omwe ali ndi malo
Kuwongolera kuwonongeka kwa batri kudzera panjinga yozama komanso kuwongolera kutentha kumakulitsa moyo wa 15-30% kupitilira machitidwe omwe amagwiritsidwa ntchito nthawi zonse.
Ndalama ndi inshuwaransi zenizeni nthawi zambiri zimatsimikizira kusankha kwaukadaulo popanda luso laukadaulo, ndi matekinoloje ena omwe amakumana ndi chiwongola dzanja cha 100-200.
Wachiwiri-mabatire a EV amoyo adzakula kuchoka pa 25-30 GWh mu 2025 kufika pa 330-350 GWh mu 2030, ndipo izi zidzapulumutsa 30-50% mtengo wa mapulogalamu oyenera.
