Ukuhlelwa kwamasu kuyisisekelo sempumelelo yezinkampani zeziteshi zokushaja izimoto zikagesi. Ingqalasizinda esebenza kahle ayidingi nje ama-hardware kuphela. Idinga ukugxila ekuthembekeni, ukuhambisana kwegridi, nokusebenza isikhathi eside. Ucwaningo lwemakethe oluvela ku-ACEAluqinisekisa ukuthi ukukhethwa kwama-hardware aqinile kuthonya ngqo ukukhula kwenethiwekhi ezimakethe zaseYurophu. Noma ngabe uphatha amanethiwekhi omphakathi noma ama-fleet angasese, ukukhethwa kwama-Mode 4 DC fast charger akho (CCS2 ne-GB/T) noma amayunithi e-Mode 3 AC wallbox (Type 2, Mennekes) kunquma ukusebenza kahle kwakho. Sebenzisa le roadmap yokusebenza ekusetshenzisweni okukhulu.

Ukusetshenziswa okuphumelelayo kuncike ekulungiseleleni okuqinile. Ngaphambi kokugqobhoza umhlaba noma ukufaka ama-hardware, qinisekisa ukuthi unezinto ezilandelayo ezilungiselelwe:

· Imibhalo eqinisekisiwe yokuhlolwa kwesizinda eqinisekisa amandla kagesi (kVA) womthwalo ohleliwe we-AC noma we-DC.

· Ukufinyelela kumadokhumenti ezobuchwepheshe emamodeli akho athile, kufaka phakathi imininingwane enemininingwane yemishini.

· Abasebenzi kagesi abaqeqeshiwe abajwayelene nezindinganiso ze-IEC 61851 kanye nezidingo zokuhambisana nekhodi yegridi yendawo.

· Uhlelo lokufaka oluqinisekisiwe olubheka izici zemvelo—ikakhulukazi esiteshini sokushaja se-EV sangaphandle—njengezidingo ze-IP-rating nokuphathwa kwekhebula.

Ngaphambi kokuthenga noma iyiphi iyunithi, kufanele uqinisekise umthamo wegidigidi. Izinkampani eziningi zeziteshi zokushaja izimoto zikagesi ziyahluleka ngoba ziyakushaya indiva ukudonswa kwamandla okuphelele. Kufanele ubale umthwalo ophezulu wawo wonke ama-DC fast charger noma isistimu yokushaja ehlukanisiwe esizeni. Uma ukunikezwa kwamandla kuphansi, isistimu izosebenza kabi. Kungenzeka futhi ukuthi ihlale icisha ama-breaker. Ukuhlela okusekelwe kudatha kuvimbela lokhu kwehluleka.

I-odithi yamandla kufanele ihole ngqo ohlelweni lwamandla olusebenzekayo. Hlela imithwalo ye-AC yesigaba esisodwa engu-230 V, amabhange okushaja ezigaba ezintathu angu-400 V kanye nanoma yiluphi uhlaka lwe-DC olungu-800 V, bese uhlola ukwanda kwe-transformer, ukugcinwa kwesikhashana kanye nesidingo esizayo. UMaruikel angakuthatha lokhu kusukela ekuhloleni ukusebenza kuze kufike ekwakhiweni kwegridi, ukucaciswa kweshaja ne-BESS, i-EMS/CMS, ukwakhiwa nokuqaliswa, okwenza ukuhlola kube yisigaba sokuqala sephrojekthi ephelele kunokuba kube umbiko okufanele umnikazi awuhumushe kubathengi abaningi.

Ukukhethwa kwezinto zangaphandle kufanele kuhlotshaniswe nendlela yokufaka kanye nomjikelezo wokusebenza. Cacisa ukuvikelwa kokungena kwe-IP65/IP67, ukumelana nokushaywa kwe-IK10 kanye nokuvikelwa kokugqwala kwe-ISO 12944, kodwa futhi qinisekisa izisekelo, imizila yamakhebula, ukupholisa nokunyakaza kwezimoto. Iphrojekthi ebhaliwe yakwa-Maruikel yafaka amashaja e-DC angu-240 kW ayisishiyagalombili ezimoto zikagesi eziyishumi nambili zobunjiniyela futhi yaqeda ukulungiswa kwesizinda nokuhlelwa ngezinsuku ezintathu. Lesi sigameko sikhombisa ukubaluleka kokuxhumanisa imishini eqinile, umsebenzi wokwakha kanye nokugunyazwa ngaphansi kweqembu elilodwa lokulethwa.

Cabanga ngomehluko phakathi kwezinto ezijwayelekile nezinqinile ngezansi:

Ukunganaki izicaciso zemvelo kuholela ekugqwaleni okusheshayo. Uzobhekana nezinkinga zokulungisa—kanye nezindleko eziphezulu—phakathi neminyaka emibili uma ihadiwe ingakhelwanga izimo zezulu. Ungalokothi uyekelele ekhwalithini yekhava emikhakheni yomphakathi. Ukwehluleka lapha kuphoqa ukushintshwa okuphelele kweyunithi.

Ukufakwa ngokomzimba kudinga ukunemba. Kufanele uqinise izinto zakho zasewallbox ezimisiwe ngokulandela iphethini yamabhawodi eqondile esencwadini yesandla. Qinisekisa ukuthi isisekelo silele futhi asinayo imfucumfucu. Amakhebuli kufanele adlule emiseleni evikelwe ukuze kuvinjelwe ukuhuzuka noma ukuchayeka emvelweni.

Umsebenzi wesisekelo awunakuxoxiswana ngawo ezindaweni ezinabantu abaningi. Sebenzisa ukhonkolo oqinisiwe ukusekela isisindo samayunithi asindayo. Umsebenzi wesisekelo ongalungile uholela ekutheni ihadiwe litsheke ngokuhamba kwesikhathi. Leli yisu lokwehluleka elivamile kumanethiwekhi omphakathi. Hlala usebenzisa ileveli yomoya ukuqinisekisa ukuthi indawo yokufaka icwecwe ngokuphelele. Uma iyunithi ihlezi nge-engeli, izikhonkwane zangaphakathi zokukhiya zingase zibambe. Lokhu kuvimba inqubo yokushaja kubasebenzisi bakho bokugcina.

Uma isifakiwe, ukuhlola ukuhlanganiswa kwenethiwekhi kubalulekile. Kufanele uqinisekise ukuthi ishaja ngayinye ye-DC esheshayo ixhumana kahle nohlelo lokuphatha olumaphakathi. Lokhu kuqinisekisa ukulinganiswa komthwalo kuyo yonke indawo. Ukuhlanganiswa okufanele kuvumela ukuqapha kwesikhathi sangempela kokusetshenziswa kwamandla. Lokhu kubalulekile enzuzweni yakho yesikhathi eside.

Hlola inkinobho yokuma okuphuthumayo kuyo yonke iyunithi. Kufanele inqamule ngokushesha konke ukugeleza kwamandla. Uma lokhu kwehluleka, iyunithi ayiphephile ukusebenza. Ngaphezu kwalokho, sebenzisa ukuhlola kokuxilonga ukuqinisekisa ukuthi imojuli yokuxhumana iyasebenza. Ukushaya indiva lesi sinyathelo kuholela ezindlekweni zokulawula. Awufuni ukuchaza ukuthi kungani izinhlelo zakho zokuphepha zazingasebenzi ngesikhathi sokuhlolwa okujwayelekile. Ukuhlola okulula kuthatha imizuzu emihlanu kuphela kodwa kusindisa isithunzi sakho.

Ukuvikelwa kwe-residual-current kudinga ukunakwa okukhethekile. Ku-Mode 4 DC fast charging, i-Type B residual current device (RCD) ehambisana ne-IEC 62423 inconywa kakhulu ngoba ikwazi ukuthola kokubili i-AC kanye ne-smooth DC residual currents. Uma i-Type A RCD isivele ifakiwe endaweni, i-RDC-DD ehambisana ne-IEC 62955 ingengezwa njengendlela yokuvikela elinganayo. I-RCD ejwayelekile yohlobo lwe-AC ayanele emandleni ephutha e-DC okungenzeka ukuthi ishaja esheshayo iwakhiqize. Ukukhethwa kokugcina kufanele kuhlale kuqinisekiswa ngokumelene nokuhlelwa kwegridi yendawo kanye nomklamo wokuvikela wemishini ethile yokushaja.

Ukuqedwa kwekhomishini kuphetha iphrojekthi. Kufanele wenze ukuhlolwa komthwalo ogcwele ukuze uqinisekise ukuthi umkhiqizo wamandla uhambisana nemininingwane ebhaliwe yamashaja akho. Bhala idatha yokusebenza eyisisekelo yeyunithi ngayinye. Lokhu kwakha indlela yokuqhathanisa yokunakekelwa okubikezelayo esikhathini esizayo.

Hlola izixhumi ukuze uthole izimpawu zokuguga. Hlola izihlungi zomoya zokungena kumakhabethe akho e-PV&ESS ahlanganisiwe njalo ngenyanga. Amayunithi ahlanzekile ahlala isikhathi eside futhi asebenza kangcono. Setha irekhodi ledijithali kukho konke ukuvakasha kwenkonzo. Uma iyunithi ikhombisa ukwehla kwamandla, hlola ngokushesha amafeni okupholisa. Ukwehluleka kwefeni iyona mbangela evamile kakhulu yokuncipha kokushisa kumashaja asheshayo e-DC.

Ngisho nengqalasizinda engcono kakhulu ibhekana nezinselele. Sebenzisa lezi zinyathelo ukulungisa izinkinga ezivamile ngokushesha:

· Iyunithi ayivuki: Hlola isiphuli esikhulu kanye nesimo sesivikeli sokulimala komhlaba. Ukuvuselela isivikelo sangaphambili ngokuvamile kuxazulula inkinga. Uma isiphuli siphinda sihluleka, hlola ukuthi kukhona ukujikeleza okufushane kukhebula lokushaja.

· Iphutha lokuxhumana: Qinisekisa kabusha isimo sokuxhumana kwe-LAN noma i-4G. Uma kuqhubeka, qalisa kabusha iyunithi yokulawula yangaphakathi. Qinisekisa ukuthi i-firewall yakho ivumela ukuhamba kwedatha okuvela kukheli le-IP elithile leshaja.

· Inkinga yokukhiya ikhebula: Qala ngokuqinisekisa ukuthi isixhumi sifakwe ngokugcwele esitsheni; indlela yokukhiya kufanele yenze umsindo ozwakalayo wokuthi "click." Uma iphini lokukhiya lingakwazi ukushelela endaweni ekhiyiwe, hlola imbobo ukuthi akunazinto zangaphandle noma imfucumfucu engase ivimbele ukuhlangana futhi sebenzisa umoya ocindezelwe ukuyihlanza uma kudingeka. Uma isixhumi sisahluleka ukukhiya ngemuva kokuhlanza, hlola isilawuli se-electronic-lock noma isignali yokuxhumana yemoto.

Ukuthembeka kuchaza abaholi bemakethe phakathi kwezinkampani zeziteshi zokushaja izimoto zikagesi. Izinsiza zakho zokusebenza kufanele zihlale zihlanganisa ukuxhumana nosekelo lobuchwepheshe lwama-24/7. Ukunakekela okusebenzayo kushibhe kunezindleko zokulungisa okulindile—kulula kangako. Gcina izingxenye zokushintsha endaweni yezindawo ezinokushintshwa okuphezulu. Ngaphezu kwalokho, ukulandelela ukusebenza kahle kwamandla kukusiza ukuthuthukisa izindleko ngokuhamba kwesikhathi.

Ngenxa yezidingo eziyisibopho ezikuMthetho Wengqalasizinda Yamafutha Okunye wase-EU (AFIR) mayelana nokuminyana kokufakwa kwenethiwekhi yokushaja yomphakathi namandla okushaja ahlanganisiwe, kanye nokulindela okujwayelekile komkhakha kokutholakala okuphezulu kwezishaja, abasebenzi kufanele bathathe isikhathi sokusebenza kwemishini njenge-KPI eyinhloko yokusebenza. Uma amayunithi akho engaxhunyiwe, ulahlekelwa yimali engenayo futhi wehluleka ukuhlangabezana nezimfuneko zombuso. Sebenzisa ukuphathwa kwamandla okuhlakaniphile ukushintsha imithwalo ngezikhathi zamahora aphezulu. Lokhu kwehlisa kakhulu izindleko zakho zikagesi.

Ama-opharetha amaningi eMpumalanga Ephakathi nase-Asia manje aseqhubekela ekugcineni kwamandla okuhlangene nelanga. Lezi zinhlelo zinciphisa umthwalo kugridi yendawo. Ziphinde zivumele ukushaja ukuthi kuqhubeke ngesikhathi sokuphazamiseka kugridi. Lokhu kudala inzuzo enkulu yokuncintisana yomkhiqizo wakho.

I-hardware kufanele ibhekane nomsebenzi wenethiwekhi yomphakathi, kodwa umphumela wezohwebo uncike ohlelweni oluphelele. UMaruikel angahlanganisa i-Mode 3 AC kanye ne-Mode 4 DC equipment nokuhlelwa kwegridi ne-transformer, i-solar PV, i-BESS, i-EMS/CMS, ukufakwa, ukusebenza kanye ne-24/7 O&M. Lesi sakhiwo se-turnkey sakha indlela eyodwa ezophendulwa kusukela ekuhlolweni kwamandla esizeni kuya ekusebenzeni okuzinzile, okuyindlela ama-opharetha anciphisa ngayo ukwehluleka kwe-interface futhi avikele isikhathi sokusebenza.
