Isiteshi Sokushaja Esiphezulu Esingu-240kW SE-NACS Esine-CHAdeMO Charger engu-150kW
Njengoba ukushintshela emhlabeni wonke ezimotweni zikagesi (ama-EV) kushesha, ingqalasizinda esekela lolu shintsho kumele ihambe endaweni eyinkimbinkimbi yezindinganiso ezincintisanayo kanye nezidingo zamandla ezikhula ngokushesha. Ngenkathi i-North American Charging Standard (i-NACS) ikhuphukele phambili emakethe yezimoto zabagibeli, ukusetshenziswa kwendabuko kanye nezimboni ezithile ze-CHAdeMO standard kusalokhu kuyisici esibalulekile se-system yokushaja yomhlaba wonke. Kubasebenzi beziteshi, inselelo icacile: ukuthi ungahlinzeka kanjani ngokushaja okusheshayo, okuvikela ikusasa kwezimoto ezintsha ezihlonyiswe yi-NACS ngaphandle kokushiya izigidi zezimoto ezithembele ku-CHAdeMO kanye nemikhumbi yezentengiselwano esesendleleni.
1. Ukufakwa kukagesi kwezokuThuthukiswa kwempahla: Isibopho Sokuhweba Somhlaba Wonke
Ezweni elinzima lokulethwa kwemishini okuhamba phambili kanye nokuthutha okunzima, ukushintsha kusuka ezinjinini zokushisa zangaphakathi kuya ezinjinini zikagesi akusekho ukukhetha. I-MIDA Power (迈依达), iminyaka eyishumi yobungcweti bobunjiniyela, iphambili kulolu guquko ngeIsiteshi Sokushaja Esiphezulu Esingu-240kW SE-NACS Esine-CHAdeMO Charger engu-150kW.
Izindawo zokuthutha zinikeza indawo ehlukile lapho isikhathi sokungasebenzi siwukulahlekelwa imali engenayo ngqo.Isiteshi Sokushaja Esiphezulu Esingu-240kW SE-NACS Esine-CHAdeMO Charger engu-150kWYakhelwe ukuhlangabezana nemijikelezo enzima yemisebenzi yezindawo zokulethwa kwezimpahla zasemadolobheni, iziteshi zezimpahla zasesikhumulweni sezindiza, kanye nemizila yokuthutha impahla yasechwebeni. Ngokusebenzisa ipulatifomu enamandla kagesi angu-1000V, i-MIDA iqinisekisa ukuthi amaveni kagesi esizukulwane esilandelayo kanye namaloli asindayo achitha isikhathi esincane emshinini wokukhipha izimpahla futhi achitha isikhathi esiningi emgwaqweni.
2. Ukwakhiwa Kobuchwepheshe: Ngaphakathi kwe-MIDA Power Stack
2.1 I-Topology ye-SiC MOSFET kanye Nokusebenza Kahle
Amashaja e-DC avamile avame ukuba nezinkinga zokwehla kokusebenza kahle uma imithwalo ingaphelele.Isiteshi Sokushaja Esiphezulu Esingu-240kW SE-NACS Esine-CHAdeMO Charger engu-150kWisebenzisa i-topology ye-Silicon Carbide (SiC) MOSFET enezigaba eziningi. Ngokungafani nezinhlelo ezijwayelekile ezisekelwe ku-IGBT, i-SiC ivumela amaza okushintsha aphezulu (kufika ku-100kHz), okunciphisa ukulahlekelwa kokushintsha ngo-30%. Lo mklamo uvumelaIsiteshi Sokushaja Esiphezulu Esingu-240kW SE-NACS Esine-CHAdeMO Charger engu-150kWukugcina ukusebenza kahle okuphezulu okungu-96.5%.
ISITHASISELO SOBCHWEPHESHE: Iphepha Elimhlophe Elichaza Ingqalasizinda Yamandla e-MIDA
Lesi sithasiselo sisebenza njengesisekelo esiphelele sobuchwepheshe sochungechunge lwe-MIDA Power DC Fast Charging. Sihlinzeka ngama-CPO (Charge Point Operators), abaphathi bemikhumbi, kanye nabatshalizimali bengqalasizinda ngokuqonda okujulile kwehadiwe, isofthiwe, kanye nezinhlaka zomthetho ezichaza uhlu lwemikhiqizo ye-MIDA ka-2026.
I. Ukwakhiwa Kwehadiwe: I-Fiziksi Yokuguqulwa Okusebenzayo Kakhulu
Enhliziyweni yesiteshi ngasinye se-MIDA DC kukhona i-modular power conversion stack esebenzisa ubuchwepheshe be-semiconductor be-wide-bandgap bamuva. Ushintsho lwethu kusuka kuma-Silicon IGBT endabuko ukuya kuma-Ama-MOSFET e-Silicon Carbide (SiC)imelela ushintsho olujwayelekile ekubuneni kwamandla kanye nokuqina kokushisa.
1.1 I-SiC MOSFET Topology kanye ne-LLC Resonant Converters
Amamojula kagesi e-MIDA angu-30kW kanye no-40kW asebenzisa i-Ibhuloho Eligcwele Elishintshiwe Ngesigaba (i-PSFB)kuhlanganiswe ne-Isiguquli se-LLC Resonantisigaba. Lokhu kulungiselelwa kuvumelaUkushintsha kwe-Zero Voltage (ZVS)kulo lonke ububanzi bomthwalo. Ngokususa ukulahlekelwa kokushintsha ngesikhathi sesigaba sokuvula, sifinyelela ukusebenza kahle kokuguqulwa okuphezulu okungu-96.5%. Ukusetshenziswa kwezinto ze-SiC kuvumela ukushintsha amaza adlula i-100kHz, okunciphisa kakhulu ivolumu ebonakalayo yezingxenye zamagnetic njenge-transformers ezivame kakhulu kanye nama-inductor, okuholela ekutheni kube nokunyakaza kwekhabhinethi okuncane kakhulu ngaphandle kokubeka engcupheni ukuphuma kwamandla.
1.2 Ukupholisa Nokuphathwa Kwemibhobho Yomoya Ehlukanisiwe
Ezindaweni zezimboni nezentengiselwano, ukwehluleka kwe-elekthronikhi kuvame ukubangelwa ukungcoliswa kwemvelo. Ubunjiniyela be-MIDA bube yiphayona le"Imigudu Yomoya Ehlukanisiwe"umklamo. Igumbi langaphakathi lihlukaniswe ngokwe-hemetically: ama-semiconductor kagesi kanye nama-magnetic kupholiswa ngomhubhe womoya ocindezelwe kakhulu, kuyilapho i-control logic, amamojula okuxhumana, kanye ne-HMI kugcinwe endaweni evaliwe, engenalo uthuli. Lokhu kuqinisekisa ukuthi ngisho nasezintweni zangaphandle ezilinganiselwe yi-IP54 noma i-IP55, uthuli oluqhubayo noma umswakama ngeke kukwazi ukuvala amabha amabhasi ane-voltage ephezulu.
II. Isendlalelo Sobuhlakani: I-Algorithm Yokuhlela Amandla ye-AI-DES
Ukushaja kwesimanje akuseyona nje into yokuletha ama-kilowatts angavuthiwe; kumayelana nokuhlelwa kwamandla okuhlakaniphile.I-AI-DES (Ukuhlelwa Kwamandla Ashukumisayo e-AI)ipulatifomu isebenza ngohlaka olunengqondo olunezigaba ezintathu:
- Isigaba 1: Ukusabela Kwegridi-Edge:Ishaja iqapha imvamisa yegridi yendawo kanye ne-voltage transients ngesilinganiso sokusampula esingu-10kHz. Uma kutholakala ukungazinzile kwegridi, uhlelo lwe-AI-DES lungalawula ukuphuma kwamandla ngaphakathi kwama-20ms ukuvimbela ukuhamba kwe-circuit breaker yendawo, okusebenza njenge-buffer yomhlinzeki wosizo.
- Isigaba 2: Ukuthuthukiswa Kwemoto Ephakathi:Isebenzisa i-telemetry ye-ISO 15118 ethi “Plug & Charge”, uhlelo lwe-AI-DES luxoxisana ngejika lokushaja elifanele ne-BMS yemoto. Lubheka izinga lokushisa lebhethri, isimo sempilo (i-SoH), kanye nokumelana kwangaphakathi ukuvimbela ukuguga kwangaphambi kwesikhathi kwamaseli e-lithium.
- Isigaba 3: Ukuphathwa Kwezimoto Zomnotho:Kuma-depot amakhulu, uhlelo luhlangana nezimakethe zamandla. Lubeka phambili ukushaja ngesikhathi samafasitela anentengo ephansi futhi lungasebenzisa izinhlelo zangaphakathi zokugcina amandla ebhethri (i-BESS) ukwenza "ukugunda okuphakeme," kugwenywe izindleko zokufunwa okuphezulu ezibekwa yizinsizakalo ngezikhathi zomsebenzi omatasa.
