Posachedwapa, Lin Zhiying adachita ngozi yaikulu yapamsewu poyendetsa Tesla Model X momwe galimotoyo idawotcha.Ngakhale kuti chifukwa chenicheni cha ngoziyi chikadafufuzidwabe, chochitikacho chayambitsa kukambirana kwakukulu pa Tesla ndi chitetezo cha galimoto yamphamvu yatsopano.
Pamene chitukuko cha magalimoto atsopano chikukula, chitetezo ndichofunika kwambiri, ndipo kukweza kwa teknoloji ya batri yamagetsi n'kofunika kwambiri kuti athetse vutoli.Qi Haiyu, pulezidenti wa Solar Tech, adauza nyuzipepala ya Securities Daily kuti ndikuyenda mofulumira kwa magalimoto atsopano amagetsi, mphamvu yamagetsi yamagetsi ikuwonjezeka, ndipo teknoloji yothamanga mofulumira ikupitiriza kukula.Pachifukwa ichi, kuwongolera chitetezo kumafunikira mayankho mwachangu.
Magalimoto atsopano amphamvu apeza zotsatira zodabwitsa mu theka loyamba la chaka chino.Deta ikuwonetsa kuti kupanga ndi kugulitsa kwa Chinamagalimoto atsopano amphamvunthawi imeneyi anali 266 ndi 2 nthawi apamwamba kuposa chaka cham'mbuyo, ndi mayunitsi 10,000 ndi mayunitsi miliyoni 2.6.Kupanga ndi kugulitsa zidafika pambiri ndi 21.6% kulowa pamsika.
Posachedwapa, Ministry of Emergency Management Fire and Rescue Bureau inatulutsa deta ya kotala loyamba la 2022, kusonyeza kuti malipoti a 19,000 a moto wapamsewu adalandiridwa, omwe 640 adakhudza magalimoto atsopano amphamvu, kuwonjezeka kwa 32% chaka ndi chaka.Zikutanthauza kuti pali ngozi zisanu ndi ziwiri zamoto zamagalimoto atsopano tsiku lililonse.
Kuonjezera apo, panali ngozi zamoto za 300 za magalimoto atsopano amphamvu padziko lonse mu 2021. Kuopsa kwa moto m'magalimoto atsopano amphamvu nthawi zambiri kumakhala kwakukulu kuposa magalimoto achikhalidwe.
Qi Haiyu akutsimikizira kuti chitetezo cha magalimoto atsopano amphamvu chakhala chodetsa nkhawa kwambiri.Ngakhale kuti magalimoto amafuta amakhalanso ndi chiopsezo cha kuyaka mwadzidzidzi kapena ngozi yamoto, chitetezo cha magalimoto atsopano opangira mphamvu, makamaka mabatire, alandira chidwi chochuluka kuchokera kumbali zonse pamene akupangidwa kumene.
"Nkhani zachitetezo zomwe zikuchitika pamagalimoto amagetsi atsopano makamaka zimangoyaka modzidzimutsa, moto kapena kuphulika kwa mabatire.Batire ikapunduka, ngakhale ingatsimikizire chitetezo ikafinya ndikofunikira. ”Zhang Xiang, Purezidenti wa New Energy Vehicle Technology Research Institute, adatero poyankhulana ndi Securities Daily.
Kukweza kwaukadaulo kwa mabatire amphamvu ndiye chinsinsi
Ziwerengero zikuwonetsa kuti ngozi zambiri zagalimoto zamphamvu zatsopano zimachitika chifukwa cha zovuta za batri.
Sun Jinhua adati kuchuluka kwamoto kwa mabatire a ternary lithiamu ndikwambiri kuposa mabatire a lithiamu iron phosphate.Malinga ndi ziwerengero za ngozi, 60% ya magalimoto amagetsi atsopano amagwiritsa ntchito mabatire a ternary, ndipo 5% amagwiritsa ntchito mabatire a lithiamu iron phosphate.
M'malo mwake, nkhondo yapakati pa ternary lithium ndi lithiamu iron phosphate siyinayime pakusankha njira yamagalimoto amagetsi atsopano.Pakadali pano, mphamvu yoyika ya mabatire a ternary lithiamu ikuchepa.Chifukwa chimodzi, mtengo wake ndi wokwera.Kwa wina, chitetezo chake sichili bwino monga lithiamu iron phosphate.
"Kuthetsa vuto lachitetezo chamagalimoto atsopano amphamvuamafuna luso lazopangapanga.”Zhang Xiang adati.Pamene opanga mabatire akukhala odziwa zambiri komanso likulu lawo lamphamvu kwambiri, njira yaukadaulo waukadaulo mu gawo la batri ikupitilizabe.Mwachitsanzo, BYD inayambitsa mabatire a blade, ndipo CATL inayambitsa mabatire a CTP.Zamakono zamakonozi zathandizira chitetezo cha magalimoto atsopano amphamvu.
Qi Haishen amakhulupirira kuti pakufunika kulinganiza kachulukidwe ka mphamvu ndi chitetezo cha mabatire amphamvu, ndipo opanga mabatire ayenera kupititsa patsogolo kuchuluka kwa mphamvu zamabatire pansi pachitetezo kuti apititse patsogolo mawonekedwe.Ndi kupita patsogolo kwa sayansi ndi ukadaulo komanso kuyesetsa kosalekeza kwa opanga mabatire, chitetezo cha ukadaulo wa batri wokhazikika wamtsogolo chidzapitilirabe, ndipo kuchuluka kwa ngozi zamoto m'magalimoto atsopano amphamvu kudzachepa pang'onopang'ono.Kuwonetsetsa chitetezo cha moyo wa ogula ndi katundu ndi chofunikira pa chitukuko cha makampani opanga magalimoto ndi opanga mabatire.
