Njengoba isidingo sezimoto zabagibeli nezimoto zezentengiselwano sikhula, amadivayisi kagesi ezimoto asetshenziswa kabanzi ezimotweni. Ukuze kuqinisekiswe ukusebenza okuvamile kwala madivayisi kagesi ohlelweni lokuphakelwa kwamandla oluzinzile, kubalulekile ukunqoba inkinga yokuphazamiseka okukhulu kwe-electromagnetic okubangelwa yizimoto ngesikhathi sokusebenza, okusakazekela ohlelweni lokuphakelwa kwamandla ngokuxhuma, ukudlulisa, kanye nemisebe, okuphazamisa ukusebenza kwemishini esebhodini. Ngakho-ke, indinganiso yamazwe ngamazwe ye-ISO 7637 ibeke phambili izidingo zokungavikeleki kwemikhiqizo kagesi yezimoto ekuphakelweni kwamandla.
Izinga le-ISO 7637, elaziwa nangokuthi: Izimoto zomgwaqo - ukuphazamiseka kukagesi okubangelwa ukuqhutshwa nokuhlanganiswa, liyizinga lokuhambisana kukagesi kwezinhlelo zikagesi zezimoto ze-12V kanye ne-24V. Lihlanganisa kokubili izingxenye zokukhuthazela kukagesi kanye nokukhishwa kokuhlolwa kokuhambisana kukagesi. Zonke lezi zindinganiso zichaza izidingo zamapharamitha zezinsimbi nemishini engasetshenziswa ukukhiqiza kabusha izingozi zikagesi nokwenza izivivinyo. Njenganamuhla, izinga le-ISO 7637 likhishwe ngezingxenye ezine. Njenganamuhla, izinga le-ISO 7637 likhishwe ngezingxenye ezine ukukhombisa izindlela zokuhlola kanye nemingcele ehlobene ngokuphelele. Ngemuva kwalokho sizokwethula ingxenye yesibili yaleli zinga, i-ISO 7637-II, esetshenziselwa ukuhlola ukuhambisana kwethebhulethi yethu eqinile.
I-ISO 7637-II ibiza ukuqhutshwa kwesikhashana kagesi emigqeni yokuphakelwa kuphela. Icacisa ukuhlolwa kwebhentshi kokuhlola ukuhambisana nezikhathi zikagesi eziqhutshwayo zemishini efakwe ezimotweni zabagibeli kanye nezimoto zezentengiselwano ezilula ezifakwe uhlelo lukagesi lwe-12 V noma izimoto zezentengiselwano ezifakwe uhlelo lukagesi lwe-24 V – kokubili ukujova kanye nokulinganisa izikhathi zikagesi. Ukuhlukaniswa kobunzima bemodi yokwehluleka kokungavikeleki ezinkathini zikagesi nakho kunikeziwe. Kuyasebenza kulezi zinhlobo zezimoto zomgwaqo, ngaphandle kohlelo lokuqhutshwa (isb. ukuvutha kwenhlansi noma injini yedizili, noma imoto kagesi).
Ukuhlolwa kwe-ISO 7637-II kufaka phakathi ama-waveform ahlukahlukene e-transient voltage. Amaphethelo akhuphukayo nawawayo ala ma-pulse noma ama-waveform ashesha, ngokuvamile ebangeni le-nanosecond noma le-microsecond. Lokhu kuhlolwa kwe-transient voltage kuklanyelwe ukulingisa zonke izingozi zikagesi izimoto ezingase zihlangane nazo ngaphansi kwezimo zangempela, kufaka phakathi i-load dump. Ukuqinisekisa ukusebenza okuzinzile kwemishini esebhodini kanye nokuphepha kwabagibeli.
Ukuhlanganisa ithebhulethi eqinile ehambisana ne-ISO 7637-II emotweni kunikeza izinzuzo eziningi. Okubaluleke kakhulu, ukuqina kwayo kuqinisekisa ukusebenza kwesikhathi eside nokusebenza okuthembekile, kunciphisa izindleko zokulungisa nokwandisa umkhiqizo jikelele. Okwesibili, ithebhulethi eqinile ehambisana ne-ISO 7637-II inikeza ukubonakala nokulawula ulwazi olubalulekile ngesikhathi sangempela, kuthuthukisa ukuxilongwa kwezimoto nokukhulisa ukusebenza kahle. Okokugcina, lawa mathebhulethi angaxhumana kalula nezinye izinhlelo zezimoto namadivayisi angaphandle, athuthukise ukuxhumana nokusebenzisana. Ngokunamathela kule ndinganiso, singakha ukwethembeka, sigxilise ukwethenjwa, futhi sinikeze imikhiqizo engcono kakhulu ehlangabezana nezidingo zamakhasimende.
Ngokuhambisana nokuvikelwa kwe-ISO 7637-II ejwayelekile ye-transient voltage, amaphilisi aqinile avela ku-3Rtablet ayakwazi ukumelana nokuphazamiseka kwezimoto okufika ku-174V 300ms futhi asekele ukunikezwa kwamandla kagesi we-DC8-36V ububanzi. Kuthuthukisa cishe ukuqina kokusebenza kwezinhlelo ezibalulekile emotweni njenge-telematics, i-navigation interface kanye nezibonisi ze-infotainment ngaphansi kwezimo ezinzima futhi kuvimbele ukulahlekelwa okubangelwa ukungasebenzi kahle.
