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.
