Ngemuva kokuqonda ukuthuthukiswa kwemakethe kwenqwaba yokushaja.- [Mayelana Nenqwaba Yokushaja Imoto Kagesi - Isimo Sokuthuthukiswa Kwemakethe],Silandele njengoba sibheka ngokujulile ukusebenza kwangaphakathi kokushaja, okuzokusiza wenze ukukhetha okungcono mayelana nendlela yokukhetha isiteshi sokushaja.

Namuhla, sizoqala ngokuxoxa ngamamojula wokushaja kanye nezitayela zawo zokuthuthuka.

1. Isingeniso samamojula wokushaja

Ngokusekelwe ohlotsheni lwamanje, olukhonaamamojula wokushaja evihlanganisa amamojula okushaja e-AC/DC, amamojula okushaja e-DC/DC, namamojula wokushaja we-V2G ane-bi-directional. Amamojula we-AC/DC asetshenziswa endaweni eyodwainqwaba yokushaja imoto kagesi, okuwenza abe module yokushaja evame kakhulu futhi esetshenziswa kaningi. Amamojula e-DC/DC asetshenziswa ezimeni ezifana namabhethri elanga e-PV ashajayo, kanye nokushajwa kwebhethri kuya emotweni, ngokuvamile atholakala kumaphrojekthi wokushaja isitoreji selanga noma amaphrojekthi wokushaja isitoreji. Amamojula wokushaja we-V2G aklanyelwe ukubhekana nezidingo zesikhathi esizayo zokusebenzisa igridi yemoto noma ukushaja okuphindwe kabili kweziteshi zamandla.

2. Isingeniso Sokushaja Amathrendi Okuthuthukiswa Kwemojuli

Ngokusetshenziswa kabanzi kwezimoto zikagesi, izinqwaba zokushaja ezilula ngokusobala ngeke zanele ukusekela ukuthuthukiswa kwazo okukhulu. Umzila wobuchwepheshe wenethiwekhi yokushaja usube yimvumelwano kuukushaja imoto yamandla amashaimboni. Ukwakha Iziteshi zokushaja kulula, kodwa ukwakha inethiwekhi yokushaja kuyinkimbinkimbi kakhulu. Inethiwekhi yokushaja iwuhlelo oluphakathi kwezimboni kanye ne-inter-disciplinary ecosystem, ebandakanya okungenani izinkambu eziyi-10 zobuchwepheshe ezifana nogesi wamandla, isilawuli sokuthumela, idatha enkulu, izinkundla zamafu, ubuhlakani bokwenziwa, i-inthanethi yezimboni, ukusatshalaliswa kwesiteshi esincane, ukulawula okukhaliphile kwemvelo, ukuhlanganiswa kwesistimu, nokusebenza nokugcinwa okuhlakaniphile. Ukuhlanganiswa okujulile kwalobu buchwepheshe kubalulekile ukuze kuqinisekiswe ukuphelela kwesistimu yenethiwekhi yokushaja.

Umgoqo wobuchwepheshe oyinhloko wamamojula wokushaja usekuklameni kwawo kwe-topology namandla okuhlanganisa. Izingxenye ezibalulekile zamamojula wokushaja zifaka amadivayisi kagesi, izingxenye kazibuthe, izihlungi, ama-capacitor, ama-chips, nama-PCB. Lapho imojula yokushaja isebenza,amandla e-AC ezigaba ezintathuilungiswa yisekethi yokulungiswa kwesici samandla asebenzayo (PFC) bese iguqulelwa kumandla e-DC wesekethe yokuguqulela ye-DC/DC. Ama-algorithms esofthiwe wesilawuli asebenza ekushintsheni kwamandla esemiconductor ngamasekhethi okushayela, ngaleyo ndlela alawule ugesi ophumayo wemojuli yokushaja kanye namanje ukushaja iphekhi yebhethri. Isakhiwo sangaphakathi samamojula wokushaja siyinkimbinkimbi, sinezingxenye ezihlukahlukene ngaphakathi komkhiqizo owodwa. Idizayini ye-topology inquma ngokuqondile ukusebenza kahle nokusebenza komkhiqizo, kuyilapho idizayini yesakhiwo sokushabalalisa ukushisa inquma ukusebenza kahle kwayo kokukhipha ukushisa, kokubili okunomkhawulo ophezulu wezobuchwepheshe.

Njengomkhiqizo we-elekthronikhi wamandla onezivimbio eziphezulu zobuchwepheshe, ukufeza izinga eliphezulu kumamojula wokushaja kudinga ukucabangela imingcele eminingi, njengevolumu, ubukhulu, indlela yokukhipha ukushisa, i-voltage ephumayo, yamanje, ukusebenza kahle, ukuminyana kwamandla, umsindo, izinga lokushisa lokusebenza, nokulahlekelwa kokulinda. Ngaphambilini, izinqwaba zokushaja zazinamandla aphansi kanye nekhwalithi, ngakho-ke izidingo zamamojula wokushaja zazingekho phezulu. Kodwa-ke, ngaphansi komkhuba wokushaja kwamandla aphezulu, amamojula wokushaja asezingeni eliphansi angaholela ezinkingeni ezibalulekile phakathi nesigaba sokusebenza esilandelayo sokushaja izinqwaba, okwandisa izindleko zokusebenza zesikhathi eside nezokugcina. Ngakho-ke,ukushaja abakhiqizi benqwabakulindeleke ukuthi ziqhubeke zikhulise izidingo zazo zekhwalithi zamamojula wokushaja, zibeke izidingo eziphakeme kumakhono obuchwepheshe abakhiqizi bamamojula wokushaja.

Lokho kuphetha ukwabelana kwanamuhla kumamojula wokushaja we-EV. Sizokwabelana ngokuqukethwe okuningiliziwe ngokuhamba kwesikhathi kulezi zihloko:

1. Ukumisa imojuli yokushaja
2. Ukuthuthukiswa kumamojula aphezulu wokushaja amandla
3. Ukuhlukahluka kwezindlela zokukhipha ukushisa
4. Ubuchwepheshe obuphezulu bamanje nobuphezulu be-voltage
5. Ukwandisa izidingo zokuthembeka
6. Ubuchwepheshe bokushaja be-V2G bi-directional
7. Ukusebenza nokugcinwa okuhlakaniphile
