Kodi ma cell a thumba ndi otetezeka kuposa ma cell a prismatic?

Mbiri yachitetezo imasiyana m'malo motengera momwe zinthu ziliri. Ma cell a prismatic amakhala ndi zolephera m'nyumba zolimba koma amapangitsa kuti pakhale kupanikizika kwambiri mkati mwazotentha-zomwe zimapangitsa kuti pakhale phokoso lachiwawa. Ma cell a thumba amalephera pang'onopang'ono chifukwa cha kutupa pang'onopang'ono, kupereka chenjezo lowonekera, koma kuyika kwawo kosinthika sikumapereka chitetezo chamkati. Makina opangidwa bwino amapeza chitetezo chofananira mosasamala za mtundu wake kudzera mu kasamalidwe koyenera ka kutentha, kamangidwe ka makina, ndi chitetezo cha kasamalidwe ka batri.

Chifukwa chiyani mafoni a m'manja amagwiritsa ntchito ma cell pouch pomwe ma EV amakonda prismatic?

Zofunikira pakugwiritsa ntchito zimayendetsa kusankha mtundu. Mafoni a m'manja amakwaniritsa makulidwe osachepera komanso kulemera kwake m'malo osawoneka bwino-maselo am'matumba amapambana izi. Magalimoto amagetsi amaika patsogolo moyo wa kayendedwe, kukhazikika kwa kutentha, ndi kulimba kwa makina kuposa kupulumutsa kulemera pang'ono{3}}ma cell a prismatic amathandiza bwino izi. Komabe, kuchotserapo kulipo: ma EV ena (mitundu ina ya Nissan Leaf) amatumiza bwino ma cell a thumba, pomwe mafoni am'manja amatha kufotokozera ma cell ang'onoang'ono a prismatic kuti akhale olimba.

Kodi zisankho zamtundu wa batri zimakhudza bwanji mtengo wa chipangizo chonsecho?

Kusankha mawonekedwe kumakhudza 15-30% ya ndalama zonse za batri zomwe zimagwiritsidwa ntchito kuposa zomwe zimagwiritsidwa ntchito ndi ma cell. Maselo a prismatic amawononga 15-20% mochulukirapo pa kilowatt-ola koma amafunikira makina othandizira osavuta. Ma cell a mthumba amasunga ndalama zama cell koma amafuna makina opondereza apamwamba komanso kasamalidwe ka matenthedwe. Pamlingo wamakina, kusiyana kwamitengo kumachepera mpaka 5-15% kutengera kuchuluka kwa kupanga ndi zofunikira zamafuta. Kagwiridwe ka ntchito ndi kudalirika kaŵirikaŵiri kumaposa kulingalira kwa mtengo wa chindunji posankha mtundu.

Zofunika Kwambiri

Ma cell a prismatic ndi thumba amayimira njira zophatikizira zosiyanasiyanakwa lithiamu-ion chemistry-zigoba zolimba zamakona anayi motsutsana ndi malaminates osinthika-iliyonse ikukhathamiritsa magwiridwe antchito osiyanasiyana m'malo moyimira umisiri wapamwamba/otsika

Kachulukidwe ka mphamvu kamakonda kamangidwe ka thumba(174 Wh/kg) kupitilira njira zina za prismatic (157-165 Wh/kg), kumasulira ku 10-15% kupulumutsa kulemera kofunikira pamagetsi onyamula komanso kugwiritsa ntchito zakuthambo.

Ubwino wowongolera kutentha ndi wamitundu ya prismatickudzera mu kutentha kwa zipolopolo zazitsulo, zomwe zimapangitsa kuti{0}mphamvu zizitulutsa mphamvu zambiri m'magalimoto ndi m'mafakitale pomwe ma cell amafunikira zida zozizirira bwino.

Mitengo yamitengo imasiyana mwanzeru: ma pouch cell amabweretsa 15-20% zotsika mtengo zopangira koma amafuna njira yokulirapo-yowonjezera ndalama zothandizira makina opangira mawotchi komanso ndalama zonse zoyendetsera matenthedwe zimasintha mkati mwa 5-15% pa sikelo

Zofunikira pakugwiritsa ntchito zimayendetsa kusankha koyenerapaziganizo zisanu ndi chimodzi: mbiri ya mphamvu, malo opangira makina, kuchuluka kwa malo, kuchuluka kwa zinthu, zofunikira pa moyo, ndi malamulo achitetezo-palibe mawonekedwe "abwino kwambiri" omwe amapezeka pakagwiritsidwe ntchito.
