Indawo enhle kakhulu yakhiwe ngendlela ehlelekile, ayitholakalanga: iyindawo lapho kudingeka khona ithrafikhi elinganisiwe, ukufinyelela kwegridi okushibhile, izindleko zesidingo ezingalawuleki, kanye nokuguquguquka kwezindlu isikhathi eside.Abaqhubi abaphatha ukukhethwa kwesayithi njengomsebenzi wokubhala phansi oqhutshwa idatha — ukuthola amaphuzu okusebenzisa, indlela yamandla, amanani entengo, kanye nemigomo yokuqashisa ngaphambi kokufaka imali — bahlala bethola imali engaphezu kontanga abamane babeke amashaja lapho izindlu zishibhile khona. Njengoba amapulatifomu e-800V/1000V eba yinto evamile, i-NACS ne-CCS2 zisebenza ndawonye ezimakethe, kanye ne-IEC 61851-23:2023 ephakamisa ibha yokuthobela imithetho, isayithi lika-2026 elakhelwe phezu kwehadiwe enwebekayo, enwebekayo kanye nendlela yamandla exoxiswane kahle izoqhubeka nokukhiqiza imali engenayo ngo-2030 — kuyilapho amaphrojekthi anganaki kakhulu ehlelwa kabusha.

I-MIDA Power iklama futhi ikhiqize i-DC charging stack ephelele — iziteshi zokushaja ezisheshayo ze-DC ezimi phansi nezihlukanisiwe, izinhlelo zamandla aphezulu ezipholile ngoketshezi, iziteshi zokushaja ezihlanganisiwe nezisebenza ngamandla elanga ze-BESS, izixazululo ezikwazi ukusebenza nge-V2G, amamojula kagesi, kanye nezixhumi — ukuze opharetha bakwazi ukufanisa ukwakheka kwehadiwe nesidingo sendawo kanye nephrofayili yegridi kunokuba benze okuphambene nalokho.
