Ukukhetha phakathi kwezinkampani zokushaja kudinga okungaphezu kokuqhathanisa amanani eyunithi. Umbuzo obalulekile ukuthi ingabe umhlinzeki angaletha isizinda esiphelele: ukusebenzeka, amandla kagesi noma e-transformer, ihadiwe ye-Mode 3 ne-Mode 4, i-solar PV, i-BESS, i-EMS/CMS, imisebenzi yokwakha, ukufakwa nokusebenza kanye ne-O&M. I-Maruikel ibekwe njengomhlinzeki wezixazululo ze-turnkey wase-Eurasia onokwethenjelwa okuphezulu kulo lonke lolu chungechunge olugcwele lokushaja namandla amasha, enciphisa ingozi yokuxhumanisa edalwa abahlinzeki abahlukene bemishini, ukwakhiwa kanye nesofthiwe.

Lapho uhlola abahlinzeki abangaba khona, bheka ihadiwe ehambisana namazinga omhlaba aqinile. Hlola uhla lwemikhiqizo yabo ngokuqhathanisa nezidingo zakho zephrojekthi ethile. Ingabe umthengisi unikeza i-ecosystem ephelele, kufaka phakathi amashaja asheshayo e-DC kanye nesitoreji samandla esihlanganisiwe? Nazi izindlela ezinhlanu ezingenakuphikiswa zenqubo yakho yokuhlola:

· Isitifiketi Nokuhambisana: Qinisekisa ukuthi zonke izinto zokusebenza zihambisana nochungechunge lwe-IEC 61851 kanye nezidingo zokumaka kwe-CE, kufaka phakathi i-Low Voltage Directive (LVD) kanye ne-Electromagnetic Compatibility Directive (EMC). Izinto zokusebenza ezinemisebenzi yokuxhumana ngaphandle kwentambo kufanele futhi zihambisane ne-Radio Equipment Directive (RED). Emakethe yase-UK, qinisekisa futhi ukuhlolwa okuzimele kwe-TÜV kanye nokumaka kwe-UKCA.

· Ukusebenza Kahle: Hlola amazinga okuguqulwa kwamandla; isibonelo, amashaja asheshayo e-DC kufanele anikeze ukusebenza kahle okungu-96% noma ngaphezulu.

· Ukuqina Kwemvelo: Qinisekisa ukuthi amakhabethe anezilinganiso eziphezulu zokungena (IP65 kuya ku-IP67), isilinganiso somthelela se-IK10 ngokumelene nokucekelwa phansi, kanye nebhokisi eliqedwe ngamazinga okuvikela ukugqwala e-ISO 12944 ezindaweni ezisogwini noma ezinomswakama ophezulu.

· Ukukhula: Ingabe umhlinzeki angakwazi ukunikeza amakhabethe e-PV&ESS asebenza ndawonye akhula ngokufakwa kwakho kwelanga?

· Ukusekelwa Kokuphila: Qinisekisa ukuthi umkhiqizi unikeza usizo lobuchwepheshe lwama-24/7 kanye newaranti ecacile yeminyaka eminingi.

Ukusebenza akusona nje isilinganiso sokumaketha. Udinga ukuqinisekisa ukuthi ama-electronics wamandla angaphakathi kwamashaja akho asheshayo e-DC angakwazi ukumelana nokushisa okuphezulu ngaphandle kokuncipha. Ngokweqiniso, uma uhlelo lwangaphakathi lokupholisa luhluleka, izindawo zakho zokushaja ziyavalwa. Lokho kubiza imali. Hlola i-umlando wenkampani kanye namazinga okukhiqiza ngaphambi kokuba uzibophezele ekuthengeni okuningi.

Ukwakhiwa kokuvikelwa kufanele kuhlolwe ngendlela efanayo nokukhipha okungahluziwe. Ekushajeni ngokushesha kwe-DC ye-Mode 4, isisetshenziswa sokusalela kwamanje (RCD) sohlobo B esihambisana ne-IEC 62423 sinconywa kakhulu ngoba sikwazi ukuthola kokubili amanzi asalelayo e-AC kanye ne-DC ebushelelezi. Uma i-RCD yohlobo A isivele ifakiwe endaweni, i-RDC-DD ehambisana ne-IEC 62955 ingengezwa njengendlela yokuvikela elinganayo. I-RCD yohlobo lwe-AC ejwayelekile ayanele emanzini asalelayo ephutha e-DC okungenzeka ukuthi ishaja esheshayo iwakhiqize. Ukukhethwa kokugcina kufanele kuhlolwe ngokumelene nokuhlelwa kwegridi yendawo kanye nokwakhiwa kokuvikelwa kwemishini yokushaja ethile. Ohlangothini lwesixhumi, qinisekisa ukuthi amayunithi e-DC athunyelwa ne-interface ye-CCS2 elindelekile kumanethiwekhi aseYurophu naseMpumalanga Ephakathi.

Ungakushayi indiva ukubaluleka kokusekelwa okuqhubekayo. Izinkampani ezithembekile zokushaja izimoto zikagesi zigcina izitoko zezingxenye zokungena emhlabeni wonke. Kufanele ubuze ukuthi zibhekana kanjani nokubuyekezwa kwezingxenye zekhompyutha noma iziqeshana ze-firmware zamashaja azo e-AC EV. Inkampani eyeka izingxenye zayo zekhompyutha ngemuva kokuthengisa iyingozi.

Izimpawu eziyisixwayiso zikhona yonke indawo emakethe yamanje. Gwema noma yimuphi umthengisi ongakwazi ukunikeza imibiko yokuhlola enemininingwane yezinhlelo zabo zokushaja ngokushesha kwe-DC. Ukusobala kuyisisekelo salesi sikhathi. Uma befihla imvelaphi yabo yokukhiqiza noma begwema ukukhuluma ngekhwalithi yezingxenye, hamba.

Ungalokothi uthenge imishini engazinaki izimiso zikagesi zesifunda. Isibonelo, ihadiwe efakwe eYurophu kufanele ilandele ngokuqinile uhlaka lwe-EU AFIR. Uma umhlinzeki ezama ukukuthengisela amayunithi ajwayelekile angenazo izimiso zokuxhumana ezifanele zesifunda sakho, uhlelo ngeke luhlanganiswe namanethiwekhi angemuva endawo. Akukho nokuncane.

Gwema abahlinzeki abaphusha ama-connector asezikhathini zakudala noma angahambisani. Hlala uqinisekisa ukuthi amayunithi akho okushaja e-AC wallbox asebenzisa ama-plug e-Type 2 (Mennekes) wokushaja kwe-Mode 3, nokuthi amayunithi e-DC asebenzisa izinga le-CCS2 lokushaja ngokushesha kwe-Mode 4 ezimakethe zaseYurophu naseMpumalanga Ephakathi. Ukusebenzisa isixhumi esingalungile kubangela izinkinga ezinkulu zokuhambisana kubasebenzisi bakho bokugcina. Kuyisicupho esilula okufanele usigweme.

Qaphela izinkampani ezikhipha zonke izingxenye ngaphandle kokuqapha. Ukulawulwa kwekhwalithi ngokuvamile kuyehla lapho imboni ingenazo izakhono zokukhiqiza kusukela ekuqaleni kuze kube sekugcineni. Hlala uqinisekisa ikhathalogi yomkhiqizo kanye nezincazelo zobuchwepheshe ukuze uqiniseke ukuthi bangabakhiqizi bokuqala.

Ngaphambi kokusayina noma yisiphi isivumelwano sokuthenga, udinga izimpendulo ezicacile. Lungiselela lolu hlu lemibuzo ukuze uhlunge labo abangasebenzi kahle. Ukuthola izimpendulo ezifanele kusenesikhathi kukusindisa izinkulungwane ezindlekweni zokunakekela esikhathini esizayo.

1. "Ingabe ama-DC fast charger akho ahambisana ngokuphelele nezindinganiso zakamuva ze-IEC 61851-23?"

2. "Ungakwazi yini ukunikeza uhlu olubhaliwe lwamaphrojekthi akho okusetshenziswa emhlabeni wonke?"

3. "Ingabe unikeza ukwenza ngokwezifiso kwe-OEM/ODM kokwenza uphawu lwakho noma izidingo ezithile zengxenyekathwane zesifunda?"

4. "Yisiphi isikhathi esilindelekile esimaphakathi phakathi kwezinkinga (MTBF) zamayunithi akho okushaja amandla aphezulu?"

5. "Ingabe isofthiwe yakho yokuxilonga kude ixhumana kanjani nezinhlelo zokuphatha indawo ezikhona?"

Ukushibha kuvame ukubiza kakhulu kulo mkhakha. Uma ubona ama-chaja ezimoto zikagesi anenani eliphansi ezithengiswayo, cabanga ukuthi yini efihliwe ngaphansi kwengubo. Amayunithi asezingeni lokungena avame ukuntula ukuvikelwa okuthuthukisiwe kwe-surge kanye nokuphathwa kokushisa okutholakala ku-hardware yekhwalithi ephezulu ehlala isikhathi eside.

Ukutshala imali ku-hardware yekhwalithi ephezulu, njengamasistimu okushaja okwabelana ngamandla athuthukisiwe, kuzikhokhela ngokwako ngokusebenzisa isikhathi sokusebenza. Wonke umzuzu i-chaja ehlala ingaxhunyiwe, ulahlekelwa imali engenayo. Iyunithi eshibhile ingase ikongelele imali ngosuku lokuqala, kodwa ingase ikubize inqwaba yemali emisebenzini nasezingxenyeni zokushintsha ngonyaka wesithathu.

Inani eliphezulu livela ekulethweni okuhlanganisiwe kanye nokuziphendulela komjikelezo wempilo. Ireferensi ebhaliwe ye-Maruikel yokusetshenziswa kabusha kwebhethri yahlanganisa ishaja esheshayo engu-180 kW namabhethri okugcina angu-200 kWh futhi yafaka isiteshi sokushaja ekusebenzeni phakathi nesonto elilodwa. Icala likhombisa indlela ukukhethwa kweshaja, ubunjiniyela bokugcina, ukwakhiwa kanye nokuqaliswa okungahlelelwa ngayo njengephrojekthi eyodwa, kuyilapho imibhalo ye-CE, TUV kanye ne-IEC 61851 isekela ukunikezwa kobuchwepheshe.

Kuningi okufanele ukucabangele. Ngaphambi kokuthi uqedele i-oda lakho, hlola lolu hlu olusheshayo:

· Ingabe izingxenye zekhompyutha zihambisana namazinga esifunda (IEC/CE)?

· Ingabe ikhona iwaranti ebhaliwe yeminyaka emi-3 ecacile?

· Ingabe usubuyekeze imibhalo yobuchwepheshe yazo zonke izinhlobo ze-AC ne-DC?

· Ingabe uqinisekisile ukuthi umhlinzeki unolwazi ngemboni yakho ethile?

· Ingabe usufinyelele ukuthola isilinganiso esisemthethweni kanye nesikhathi sokuthumela?

Ngaphambi kokusayina, linganisa umhlinzeki nge-site assessment, ukwakhiwa kwegridi ne-transformer, ukuhlanganiswa kwe-PV-ESS, i-hardware yokushaja, i-EMS/CMS, ukwakhiwa, ukusebenza, izingxenye zokushintsha kanye ne-O&M. Intengo ephansi yemishini ayikwazi ukunxephezela umthwalo ongekho ezindaweni zokuxhumana. Uzakwethu wezebhizinisi onamandla kakhulu yilowo ongakwazi ukuletha nokusekela impahla yokusebenza ephelele, hhayi nje ukuthumela ibhokisi elihambisana nemigomo.
