Pamene chidwi cha dziko pa chitukuko chokhazikika chikukulirakulira,magalimoto amagetsi atsopano (NEVs)akukhala chisankho chodziwika bwino pamaulendo amtsogolo. China ili patsogolo padziko lonse lapansi pankhani yaukadaulo waukadaulo komanso kukwezeleza msika pantchito yamagalimoto amagetsi atsopano, makamaka pakupititsa patsogolo ukadaulo wa batri. Nkhaniyi ifufuza za ubwino wa mabatire a galimoto yamagetsi aku China, makamaka ntchito yaikulu ya ma capacitor mu nsanja yamagetsi yamagetsi yamagetsi OBCs (majaja pa bolodi), komanso zomwe zachitika posachedwa pamakampani opanga magalimoto amphamvu posachedwapa.
1. Ubwino waukulu wa nsanja yamphamvu kwambiri ya OBC
Mu dongosolo la batri la magalimoto atsopano amphamvu, OBC yomwe ili pa-board ndiye chigawo chachikulu cha kulipiritsa ndi kasamalidwe ka mphamvu, ndipo ntchito yake imakhudza mwachindunji kuyendetsa bwino ndi kudalirika kwa galimoto yonse. Magalimoto amphamvu atsopano akamakula kupita ku 800V high-voltage magetsi ndi ma voltages apamwamba (monga 1200V), kukweza kwaukadaulo kwa OBC ndikofunikira kwambiri. Zomangamanga zamapulatifomu apamwamba kwambiri sizimangothandizira kuyitanitsa mwachangu, komanso zimazindikira kuyitanitsa kwapawiri ndi kutulutsa, zomwe zimapangitsa kuti batire ikhale yabwino.
Pochita izi, ma capacitor amatenga gawo lofunikira kwambiri ngati "malo osungiramo mphamvu ndi kusefa" a OBC ndi DCDC (DC-DC converter). Yankho lapamwamba la capacitor lomwe linakhazikitsidwa ndi Yongming lapangidwa kuti likwaniritse zofunikira zokhazikika pamagetsi apamwamba, ma frequency apamwamba komanso kutentha kwambiri. Zogulitsa zake monga nyanga yamadzimadzi a aluminiyamu electrolytic capacitors, plug-in aluminium electrolytic capacitors, ma capacitor olimba amadzimadzi osakanizidwa ndi ma capacitor opanga mafilimu onse ali ndi mwayi wopirira voteji, kachulukidwe kake komanso moyo wautali, zomwe zimapereka chitsimikizo champhamvu champhamvu zamagetsi zamagetsi zatsopano.
2. Ubwino waukadaulo wa Yongming capacitors
Kugwiritsa ntchito ma capacitor a Yongming mu makina a OBC & DCDC a magalimoto atsopano amphamvu akuwonetsa ubwino wake wapadera pamakina a batri othamanga kwambiri.
(1) Liquid Horn Aluminiyamu Electrolytic Capacitor: Mndandanda wa ma capacitor ali ndi mawonekedwe opirira kwambiri komanso ma ripple apano, ndipo amatha kupereka chithandizo chokhazikika chamagetsi pakusintha kwamagetsi ndi ma voteji omwe amakumana nawo pafupipafupi mu OBC. Pambuyo poyesa kukalamba kwamphamvu kwambiri komanso kupirira kwathunthu, kukhazikika kwake kwanthawi yayitali komanso kudalirika kwakukulu kumatsimikizika.
(2) Liquid pulagi-mu zotayidwa electrolytic capacitor: LKD mndandanda capacitors kuchita bwino mu kutentha mkulu ndi danga yaying'ono, akhoza kugwira ntchito stably mu kutentha kutentha kwa 105 ℃, ndi kuzolowera zinthu nkhanza mkulu voteji ndi pafupipafupi mkulu. Mapangidwe ake ophatikizika amamupangitsa kuti azipereka kusefa koyenera komanso kusunga mphamvu ngakhale pamalo ochepa.
(3) Solid-liquid hybrid capacitor: Capacitor iyi imapambana kwambiri pakuchulukira kwamphamvu komanso kutsika pang'ono, ndipo imatha kukhalabe ndi mphamvu yokhazikika pa kutentha kwakukulu, kuwonetsetsa kuti dongosololi likugwira ntchito bwino.
(4) Filimu capacitor: Kupirira kwakukulu kwamagetsi, kutsika kwa ESR ndi makhalidwe a moyo wautali wa ma capacitor opanga mafilimu amawapangitsa kukhala chotchinga chachitetezo pakugwiritsa ntchito magalimoto atsopano amphamvu. Amatha kupirira ma voltages mpaka 1200V ndikukhalabe ndikuchita bwino m'malo ovuta.
3. Zochitika Zamakampani ndi Mawonekedwe Amtsogolo
Posachedwa, msika wamagalimoto amphamvu aku China ukupitilirabe kutentha, ndipo kuthandizira kwa mfundo ndi luso laukadaulo zapitiliza kulimbikitsa chitukuko chamakampani. Malinga ndi zidziwitso zaposachedwa, mu theka loyamba la 2023, kugulitsa kwa magalimoto atsopano ku China kudakwera ndi 50% pachaka, komwe kupititsa patsogolo ukadaulo wa batri ndichinthu chofunikira kwambiri chomwe chikuyendetsa kukula kwa malonda. Makamaka pankhani yaukadaulo wothamangitsa mwachangu komanso kachulukidwe kamagetsi a batri, makampani aku China achepetsa pang'onopang'ono kusiyana ndi kutsogolera kwapadziko lonse lapansi.
Kuonjezera apo, pamene dziko lapansi likuyang'anitsitsa chitetezo cha chilengedwe ndi chitukuko chokhazikika, mayiko ndi madera ambiri ayamba kuwonjezera thandizo lawo kwa magalimoto atsopano amphamvu. Kutumiza kwa China kwa magalimoto amagetsi atsopano kukuchulukirachulukira, kukopa chidwi cha ogulitsa ambiri ochokera kumayiko ena komanso amalonda pawokha.
Mwachidule, ubwino wa mabatire a galimoto yamagetsi aku China ali mu mphamvu zawo zapamwamba, kudalirika kwakukulu ndi moyo wautali, zomwe, kuphatikizapo luso lamakono la Yongming capacitors, zimapereka mphamvu zothandizira pa chitukuko chamtsogolo cha magalimoto amphamvu. Ndi kukula kosalekeza kwa kufunikira kwa msika, ogulitsa mayiko ndi amalonda payekha adzawona kuthekera kwakukulu ndi mwayi wamitundu yaku China posankha magalimoto amagetsi atsopano.
