Ngemva kokuqonda intuthuko yemakethe yenqwaba yokushaja.- [Mayelana Nenqwaba Yokushaja Izimoto Zikagesi – Isimo Sokuthuthukiswa KwemaketheSilandele njengoba sibheka ngokujulile ukusebenza kwangaphakathi kweposi lokushaja, okuzokusiza ukuthi wenze izinqumo ezingcono mayelana nendlela yokukhetha isiteshi sokushaja.

Namuhla, sizoqala ngokuxoxa ngamamojula okushaja kanye nezitayela zawo zokuthuthukiswa.

1. Isingeniso kumaMojula Okushaja

Ngokusekelwe ohlotsheni lwamanje, olukhonaamamojula okushaja e-evfaka amamojula okushaja e-AC/DC, amamojula okushaja e-DC/DC, kanye namamojula okushaja e-V2G aqondiswa yizinhlangothi zombili. Amamojula e-AC/DC asetshenziswa ngendlela eyodwaizinqwaba zokushaja izimoto zikagesi, okwenza kube yimojuli yokushaja esetshenziswa kabanzi futhi evame ukusetshenziswa. Amamojula e-DC/DC asetshenziswa ezimweni ezifana namabhethri okushaja e-PV yelanga, kanye nokushaja ibhethri emotweni, okuvame ukutholakala kumaphrojekthi okushaja isitoreji selanga noma kumaphrojekthi okushaja isitoreji. Amamojula okushaja e-V2G aklanyelwe ukubhekana nezidingo zesikhathi esizayo zokuxhumana kwegridi yemoto noma ukushaja okuqondiswayo kweziteshi zamandla.

2. Isingeniso Sezindlela Zokuthuthukisa Imodyuli Yokushaja

Njengoba izimoto zikagesi sezisetshenziswa kabanzi, kusobala ukuthi ama-charging piles alula ngeke anele ukusekela intuthuko yazo enkulu. Indlela yobuchwepheshe yenethiwekhi yokushaja isibe yisivumelwano ku-ukushaja imoto entsha yamandlaimboni. Ukwakha iziteshi zokushaja kulula, kodwa ukwakha inethiwekhi yokushaja kuyinkimbinkimbi kakhulu. Inethiwekhi yokushaja iyisistimu yokusebenza yezimboni kanye nemikhakha eyahlukene, ehilela okungenani amasimu obuchwepheshe ayi-10 njenge-elekthronikhi yamandla, ukulawula ukuthunyelwa, idatha enkulu, amapulatifomu amafu, ubuhlakani bokwenziwa, i-inthanethi yezimboni, ukusatshalaliswa kweziteshi ezincane, ukulawula kwemvelo okuhlakaniphile, ukuhlanganiswa kwesistimu, kanye nokusebenza nokugcinwa okuhlakaniphile. Ukuhlanganiswa okujulile kwalezi zobuchwepheshe kubalulekile ukuqinisekisa ukuphelela kohlelo lwenethiwekhi yokushaja.

Isithiyo esiyinhloko sobuchwepheshe samamojula okushaja sisekuklanyweni kwawo kwe-topology kanye namakhono okuhlanganisa. Izingxenye ezibalulekile zamamojula okushaja zifaka amadivayisi kagesi, izingxenye zikagesi, ama-resistor, ama-capacitor, ama-chips, nama-PCB. Uma imojula yokushaja isebenza,Amandla e-AC anezigaba ezintathuilungiswa yisekethe yokulungisa amandla asebenzayo (i-PFC) bese iguqulwa ibe amandla e-DC yesekethe yokuguqula i-DC/DC. Ama-algorithms esofthiwe esilawuli asebenza kuma-switch amandla e-semiconductor ngokusebenzisa amasekethe okushayela, ngaleyo ndlela alawula i-voltage yokukhipha yemojula yokushaja kanye nogesi ukuze ishaje iphakethe lebhethri. Isakhiwo sangaphakathi samamojula okushaja siyinkimbinkimbi, sinezingxenye ezahlukahlukene ngaphakathi komkhiqizo owodwa. Idizayini ye-topology inquma ngqo ukusebenza kahle komkhiqizo kanye nokusebenza kwawo, kuyilapho ukwakheka kwesakhiwo sokusabalalisa ukushisa kunquma ukusebenza kahle kwawo kokusabalalisa ukushisa, kokubili kunemingcele ephezulu yobuchwepheshe.

Njengomkhiqizo kagesi osebenzisa amandla onezithiyo zobuchwepheshe eziphezulu, ukufeza ikhwalithi ephezulu kumamojula okushaja kudinga ukucabangela amapharamitha amaningi, njengevolumu, isisindo, indlela yokusabalalisa ukushisa, i-voltage yokuphuma, i-current, ukusebenza kahle, ubuningi bamandla, umsindo, izinga lokushisa lokusebenza, kanye nokulahlekelwa okulindile. Ngaphambilini, ama-pile okushaja ayenamandla nekhwalithi ephansi, ngakho-ke izidingo zamamojula okushaja zazingekho phezulu. Kodwa-ke, ngaphansi komkhuba wokushaja ngamandla aphezulu, amamojula okushaja asezingeni eliphansi angaholela ezinkingeni ezinkulu ngesikhathi sesigaba sokusebenza esilandelayo sama-pile okushaja, okwandisa izindleko zokusebenza nokugcinwa kwesikhathi eside. Ngakho-ke,abakhiqizi benqwaba yokushajakulindeleke ukuthi bathuthukise izidingo zabo zekhwalithi zamamojula okushaja, okubeka izidingo eziphezulu emakhonweni obuchwepheshe abakhiqizi bamamojula okushaja.

Lokho kuphetha ukwabelana kwanamuhla ngamamojula okushaja i-EV. Sizokwabelana ngokuqukethwe okuningiliziwe kamuva ngalezi zihloko:

1. Ukuqiniswa kwemojuli yokushaja
2. Ukuthuthukiswa kwamamojula okushaja amandla aphezulu
3. Ukuhlukahluka kwezindlela zokusabalalisa ukushisa
4. Ubuchwepheshe bamandla aphezulu kanye nobe-voltage ephezulu
5. Izidingo zokwethenjelwa ezikhulayo
6. Ubuchwepheshe bokushaja be-V2G obuqondisa zombili
7. Ukusebenza nokugcinwa okuhlakaniphile
