Isiteshi Sokushaja Esisheshayo se-DC esingu-120kW esingu-240kW GBT Esinokulinganisela Komthwalo Oguquguqukayo
Ezweni elishintsha ngokushesha lengqalasizinda yezimoto zikagesi (EV), inselele ayisekho nje ngokuhlinzeka ngamandla aluhlaza; imayelana nokuphatha lawo mandla ngokunemba kokuhlinzwa. Njengoba amandla ebhethri enyuka futhi isivinini sokushaja siba yinto ebalulekile yokuncintisana ezindaweni zezentengiselwano, ikhono lokusabalalisa amandla ngendlela efanele ezimotweni eziningi seliyisici esibalulekile sohlelo lokushaja olusezingeni eliphezulu. I-MIDA Power (迈依达), umholi womhlaba wonke ku-electronics yamandla esebenza kahle, uyaziqhenya ngokwethula uchungechunge lokushaja okusheshayo lwe-120kW kanye ne-240kW GBT DC. Ngobuchwepheshe bethu obukhethekile be-Dynamic Load Balancing (DLB), lezi ziteshi zenzelwe ukwandisa ukusetshenziswa kwempahla ngenkathi kunciphisa ukucindezeleka kugridi yendawo. Kungakhathaliseki ukuthi kuyisiteshi sokuphumula somgwaqo omatasa, idepho yamabhasi kamasipala, noma isikhungo sokushaja sezentengiselwano, uchungechunge lwe-MIDA GBT lunikeza ubuhlakani, ukuthembeka, kanye nesivinini esidingekayo ukuze kunikezwe amandla ikusasa lezokuthutha.
1. Ukufakwa kukagesi kwezokuThuthukiswa kwempahla: Isibopho Sokuhweba Somhlaba Wonke
Ezweni elinzima lokulethwa kwemishini ngokushesha kanye nokuthutha okunzima, ukushintsha kusuka ezinjinini zokushisa zangaphakathi kuya ezinjinini zikagesi akusekho ukukhetha. I-MIDA Power, ngeminyaka yayo yobuchwepheshe bobuchwepheshe, ihamba phambili kulolu guquko ngeIsiteshi Sokushaja Esisheshayo se-DC esingu-120kW esingu-240kW GBT Esinokulinganisela Komthwalo Oguquguqukayo.
Izindawo zokuthutha zinikeza indawo ehlukile lapho isikhathi sokungasebenzi siwukulahlekelwa imali engenayo ngqo.Isiteshi Sokushaja Esisheshayo se-DC esingu-120kW esingu-240kW GBT Esinokulinganisela Komthwalo OguquguqukayoYakhelwe 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 Esisheshayo se-DC esingu-120kW esingu-240kW GBT Esinokulinganisela Komthwalo Oguquguqukayoisebenzisa 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 Esisheshayo se-DC esingu-120kW esingu-240kW GBT Esinokulinganisela Komthwalo Oguquguqukayoukugcina 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.
