Ngokuthuthuka okukhulu kwemakethe yezimoto ezintsha zamandla, amashaja ezimoto, njengenye yezingxenye eziyinhloko, aguqukela ekusebenzeni kahle okuphezulu, ukwenziwa kube lula kanye nokuthembeka okuphezulu.
I-Shanghai Electronics Co., Ltd., ngobuchwepheshe bayo obusha be-capacitor, ayisizi nje kuphela i-Xiaomi Fast Charge ukuthi ifinyelele impumelelo emkhakheni we-electronics yabathengi, kodwa futhi inikeza ukwesekwa okubalulekile kokuthuthukiswa kobuchwepheshe bamashaja ezimoto.
1. Usayizi omncane kanye nobuningi bamandla aphezulu: ukujikeleza kwesikhala kwamashaja ezimoto
Enye yezinto eziyinhloko zokuncintisana kwama-capacitor isekuklanyweni kwawo komqondo "wosayizi omncane, umthamo omkhulu". Isibonelo, uhlobo lwe-lead oluwuketsheziAma-capacitor ochungechunge lwe-LKM(450V 8.2μF, usayizi ongu-8 * 16mm kuphela) oklanyelwe izibhamu zokushaja ze-Xiaomi zenza imisebenzi emibili yokubopha amandla kanye nokuzinzisa i-voltage ngokwenza ngcono izinto zangaphakathi nezakhiwo.
Lobu buchwepheshe busebenza futhi kumashaja ezimoto – endaweni elinganiselwe ebhodini, ama-capacitor amancane angakhuphula kakhulu ubukhulu bamandla emojuli yokushaja ngenkathi enciphisa ingcindezi yokushaja kokushisa. Ngaphezu kwalokho, uchungechunge lwe-KCX (400V 100μF) kanye nama-capacitor e-NPX series solid-state (25V 1000μF) aklanyelwe ngqo ukushaja okusheshayo kwe-GaN anikeze izixazululo ezivuthiwe zokuguqulwa okuphumelelayo kwe-DC/DC kwamashaja ebhodini ngezici zawo zemvamisa ephezulu kanye ne-impedance ephansi.
2. Ukumelana nezimo ezimbi kakhulu: Isiqinisekiso sokuthembeka kwezimo ezikhona
Amashaja asebhodini adinga ukumelana nezimo zokusebenza eziyinkimbinkimbi njengokudlidliza, izinga lokushisa eliphezulu, kanye nomswakama ophezulu. Ama-capacitor aklanyelwe ukumelana nokushaywa kombani kanye nemisinga emikhulu ye-ripple ephindaphindwayo. Isibonelo, uchungechunge lwe-LKM lungasebenza ngokuzinzile endaweni engu--55℃ ~ 105℃ enokuphila okufika emahoreni angu-3000.
Ubuchwepheshe bayo be-solid-liquid hybrid capacitor (njenge-anti-vibration capacitor esetshenziswa kuma-charger asebhodini) budlulile ezitifiketini ze-IATF16949 kanye ne-AEC-Q200 futhi busetshenziswe ngempumelelo kubalawuli besizinda kanye namamojula okushaja ezimoto ezintsha zamandla njenge-BYD. Lokhu kuthembeka okuphezulu kuyisidingo esiyinhloko sama-charger asebhodini ukuze abhekane nezimo ezinzima.
3. Ukusebenza kahle kwemvamisa ephezulu kanye nokwenza ngcono ukusebenza kahle kwamandla: ukufanisa ubuchwepheshe be-semiconductor besizukulwane sesithathu
Izici zemvamisa ephezulu yamadivayisi e-semiconductor esizukulwane sesithathu njenge-gallium nitride (GaN) kanye ne-silicon carbide (SiC) zibeka izidingo eziphakeme ekuphenduleni kwemvamisa ephezulu kanye nokulahlekelwa okuphansi kwama-capacitor.
Uchungechunge lwe-KCX lungazivumelanisa ne-topology ye-resonant ye-LLC ephindaphindayo futhi luthuthukise ukusebenza kahle kwamandla okuphelele kwamashaja asebhodini ngokunciphisa i-ESR (ukumelana nochungechunge olulinganayo) nokuthuthukisa ukumelana kwamanje kwe-ripple.
Isibonelo, ukusebenza kahle kokulungisa amandla okuthuthukisiwe kochungechunge lwe-LKM ezibhanini zokushaja ze-Xiaomi kunciphisa ngqo ukulahleka kwamandla ngesikhathi sokushaja. Lokhu okuhlangenwe nakho kungadluliselwa esimweni sokushaja okusheshayo esinamandla aphezulu ngaphakathi.
4. Ukubambisana kwemboni kanye namathemba esikhathi esizayo
Imodeli yokubambisana neXiaomi (njengokuthuthukiswa kwe-capacitor eyenziwe ngokwezifiso) inikeza imodeli yensimu yamashaja angaphakathi. Ithimba layo lobuchwepheshe lifinyelele ukulingana okunembile kwama-capacitor namadivayisi kagesi ngokuhlanganyela ngokujulile ocwaningweni nasekuthuthukisweni kwabakhiqizi bamandla (njengokubambisana nabakhiqizi bama-chip njenge-PI ne-Innoscience).
Esikhathini esizayo, ngokwandiswa kwamapulatifomu aphezulu e-800V kanye nobuchwepheshe bokushaja, kuthuthukiswa uchungechunge lwe-capacitor olunamandla aphezulu, okulindeleke ukuthi lukhuthaze kakhulu ukuthuthukiswa kwamashaja angaphakathi kwebhodi abe lula futhi ahlanganisiwe.
Isiphetho
Kusukela kuma-elekthronikhi abathengi kuya emkhakheni wezimoto, ama-capacitor abonise indima ebalulekile yama-capacitor “njengezindawo zokuphatha amandla” ngokusebenzisa ubuchwepheshe obusha kanye nokuzivumelanisa nezimo. Ukubambisana kwayo okuphumelelayo ne-Xiaomi Fast Charge akugcini nje ngokuhlinzeka ngezixazululo ezisebenzayo emakethe yabathengi, kodwa futhi kufaka umfutho omusha ekuthuthukisweni kobuchwepheshe bamashaja asebhodini. Iqhutshwa yizimoto zamandla amasha kanye nobuchwepheshe bokushaja okusheshayo, ubuchwepheshe be-capacitor obuncane kanye nokuthembeka okuphezulu buzoqhubeka nokuhola izinguquko embonini.
