Ngenxa yokwanda kwesidingo seemoto zabakhweli kunye nezithuthi zorhwebo, izixhobo ze-elektroniki zezithuthi zisetyenziswa kakhulu kwiimoto. Ukuze kuqinisekiswe ukusebenza okuqhelekileyo kwezi zixhobo ze-elektroniki kwinkqubo yokubonelela ngombane ezinzileyo, kubalulekile ukoyisa ingxaki yokuphazamiseka okukhulu kwe-electromagnetic okubangelwa zizithuthi ngexesha lokusebenza, okusasazeka kwinkqubo yokubonelela ngombane ngokudityaniswa, ukuhanjiswa, kunye nemitha, okuphazamisa ukusebenza kwezixhobo ezikwibhodi. Ke ngoko, umgangatho wamazwe ngamazwe we-ISO 7637 ubeka phambili iimfuno zokungakhuseleki kwiimveliso ze-elektroniki zezithuthi kubonelelo lombane.
Umgangatho we-ISO 7637, okwaziwa ngokuba yi: Izithuthi zendlela – Ukuphazamiseka kombane okubangelwa kukuqhuba kunye nokudibanisa, ngumgangatho wokuhambelana kombane kwiinkqubo zombane ze-12V kunye ne-24V zeemoto. Ubandakanya zombini iindawo zokunyamezela kombane kunye nokukhupha umbane zovavanyo lokuhambelana kombane. Yonke le migangatho ichaza iimfuno zeparameter zezixhobo kunye nezixhobo ezinokusetyenziselwa ukuvelisa iingozi zombane kunye nokwenza iimvavanyo. Ukuza kuthi ga namhlanje, umgangatho we-ISO 7637 ukhutshwe kwiindawo ezine. Ukuza kuthi ga namhlanje, umgangatho we-ISO 7637 ukhutshwe kwiindawo ezine ukubonisa iindlela zovavanyo kunye neeparameter ezinxulumene nazo ngokupheleleyo. Emva koko siza kwazisa inxalenye yesibini yalo mgangatho, i-ISO 7637-II, esetyenziselwa ukuvavanya ukuhambelana kwethebhulethi yethu eqinileyo.
I-ISO 7637-II ibiza ukuhanjiswa kombane okuguquguqukayo kwimigca yokubonelela kuphela. Icacisa uvavanyo lwebhentshi lokuvavanya ukuhambelana ne-transients zombane eziqhutywayo zezixhobo ezifakwe kwiimoto zabakhweli kunye nezithuthi zorhwebo ezilula ezifakwe inkqubo yombane ye-12 V okanye izithuthi zorhwebo ezifakwe inkqubo yombane ye-24 V – zombini ukujova kunye nokulinganisa ii-transients. Uhlu lobunzima bendlela yokusilela kokungakhuseleki kwii-transients nalo lunikiwe. Iyasebenza kwezi ntlobo zezithuthi zendlela, ngaphandle kwenkqubo yokuqhubeleka (umz. i-spark ignition okanye injini yedizili, okanye i-electric motor).
Uvavanyo lwe-ISO 7637-II luquka ii-waveforms ezahlukeneyo ze-transient voltage. Ii-edges eziphakamayo nezihlayo zezi pulses okanye ii-waveforms zikhawuleza, zihlala zikwi-nanosecond okanye kwi-microsecond range. Ezi zilingo ze-transient voltage zenzelwe ukulinganisa zonke iingozi zombane ezinokudibana neemoto phantsi kweemeko zokwenyani, kubandakanya nokulahla umthwalo. Ukuqinisekisa ukusebenza okuzinzileyo kwezixhobo ezisebhodini kunye nokhuseleko lwabakhweli.
Ukudibanisa ithebhulethi eqinileyo ehambelana ne-ISO 7637-II kwisithuthi kunika iingenelo ezininzi. Eyona nto iphambili, ukuqina kwayo kuqinisekisa ukusebenza kwexesha elide kunye nokusebenza okuthembekileyo, kunciphisa iindleko zokulungisa kunye nokunyusa imveliso iyonke. Okwesibini, ithebhulethi eqinileyo ehambelana ne-ISO 7637-II inika ukubonakala kwangempela kunye nolawulo lolwazi olubalulekileyo, iphucula ukuxilongwa kwesithuthi kwaye inyusa ukusebenza kakuhle. Okokugqibela, ezi thebhulethi zinokudibana ngokulula nezinye iinkqubo zesithuthi kunye nezixhobo zangaphandle, ziphucula unxibelelwano kunye nokusebenzisana. Ngokunamathela kulo mgangatho, sinokwakha ukuthembeka, sikhuthaze ukuthembana, kwaye sinikezele ngeemveliso ezigqwesileyo ezihlangabezana neemfuno zabathengi.
Ihambelana nokhuseleko oluqhelekileyo lwe-ISO 7637-II lwe-transient voltage, iithebhulethi eziqinileyo ezivela kwi-3Rtablet ziyakwazi ukumelana nempembelelo yokunyuka kwemoto ukuya kuthi ga kwi-174V 300ms kwaye zixhasa umbane we-DC8-36V wide voltage. Iphucula phantse ukuqina kokusebenza kweenkqubo ezibalulekileyo ezisetyenziswa emotweni ezifana ne-telematics, i-navigation interfaces kunye ne-infotainment displays phantsi kweemeko ezinzima kwaye ithintela ilahleko ezibangelwa kukungasebenzi kakuhle.
