16. Isiphelo: Izinto ezibalulekileyo ekufuneka ziqwalaselwe ngabathengi abanzima

Ukukhetha itshaja yeklasi ye-480kW kwiinqwelo zeenqwelo zeKlasi yesi-8 sisigqibo esithatha iminyaka elishumi esichaphazela ukusebenza, iindleko zeenkonzo, kunye nokwaneliseka komqhubi. Gcina le migaqo iphambili kuvavanyo lwakho:

• Amandla aqhubekekayo adlula amandla aphezulu.Itshaja ekwaziyo ukumelana ne-480kW ixesha elipheleleyo lokutshintsha iiyure ezine ixabisa ngaphezu kwetshaja ekwaziyo ukumelana ne-480kW kangangemizuzu engamashumi amabini.
• Ubunjineli bobushushu yeyona nto ibangela umahluko.Kula manqanaba ombane, umahluko phakathi kwetshaja ethembekileyo kunye nentloko ebuhlungu yokugcinwa uhlala kwi-loop yokupholisa, kwi-connector, kunye nokuhamba komoya kwikhabhinethi.
• Ukupholisa ulwelo kuyimfuneko, akunyanzelekanga.Ukususela kwintambo ukuya kwiimodyuli zamandla, ulawulo lwe-coolant lugqiba ixesha lokuphumla kubushushu basehlotyeni nakwingqele yasebusika.
• Isoftware sisiseko.I-OCPP, i-ISO 15118, ukuxilongwa okukude, kunye nohlaziyo lwe-OTA zimisela ukuba inethiwekhi yakho itshintsha ngokukhawuleza kangakanani izithuthi ezintsha, amaxabiso, kunye nemigaqo.
• Cwangcisa i-MCS namhlanje.Khetha umthengisi onesakhiwo sekhabhathi esele sinendlela yokuhlaziya i-MCS ebhaliweyo, ngoko ke utyalo-mali lwanamhlanje lwe-480kW aluyi kunciphisa izithuthi zakho kwiminyaka emihlanu.
