Popeza magalimoto okwera anthu ndi magalimoto amalonda akuchulukirachulukira, zida zamagetsi zamagalimoto zimagwiritsidwa ntchito kwambiri m'magalimoto. Pofuna kuonetsetsa kuti zida zamagetsi izi zikugwira ntchito bwino mu dongosolo lokhazikika lamagetsi, ndikofunikira kuthana ndi vuto la kusokonezeka kwakukulu kwamagetsi komwe kumachitika ndi magalimoto panthawi yogwira ntchito, komwe kumafalikira ku dongosolo lopereka magetsi kudzera mu kulumikizana, kupititsa patsogolo mphamvu, ndi kuwala, zomwe zimasokoneza magwiridwe antchito a zida zomwe zili m'bwalo. Chifukwa chake, muyezo wapadziko lonse lapansi wa ISO 7637 wapereka zofunikira za chitetezo chamthupi pazinthu zamagetsi zamagalimoto pamagetsi.
Muyezo wa ISO 7637, womwe umadziwikanso kuti: Magalimoto apamsewu - Kusokoneza kwamagetsi komwe kumachitika chifukwa cha kuyendetsa ndi kulumikizana, ndi muyezo wogwirizana ndi maginito amagetsi pamagalimoto amagetsi a 12V ndi 24V. Umaphatikizapo magawo onse awiri a kupirira kwa maginito ndi kutulutsa kwamagetsi poyesa kuyanjana ndi maginito amagetsi. Miyezo yonseyi imafotokoza zofunikira pazida ndi zida zomwe zingagwiritsidwe ntchito kubwereza ngozi zamagetsi ndikuchita mayeso. Masiku ano, muyezo wa ISO 7637 watulutsidwa m'magawo anayi. Masiku ano, muyezo wa ISO 7637 watulutsidwa m'magawo anayi kuti uwonetse njira zoyesera ndi magawo ena okhudzana nawo mokwanira. Kenako tidzayambitsa gawo lachiwiri la muyezo uwu, ISO 7637-II, lomwe limagwiritsidwa ntchito kuyesa kuyanjana kwa piritsi lathu lolimba.
ISO 7637-II imatchula kuti magetsi a transient conduction m'mizere yoperekera zinthu zokha. Imatchula mayeso a bench kuti ayesere kuyanjana ndi magetsi a transient omwe amayendetsedwa ndi zida zomwe zayikidwa pamagalimoto okwera anthu ndi magalimoto amalonda opepuka okhala ndi makina amagetsi a 12 V kapena magalimoto amalonda okhala ndi makina amagetsi a 24 V - pobayira komanso poyesa magetsi a transient. Kugawa kwa kulephera kwa chitetezo ku magetsi a transient kumaperekedwanso. Imagwiranso ntchito pamitundu iyi ya magalimoto apamsewu, osatengera makina oyendetsa (monga kuyatsa kwa spark kapena injini ya dizilo, kapena mota yamagetsi).
Mayeso a ISO 7637-II akuphatikizapo mafunde osiyanasiyana amagetsi osinthasintha. Mphepete zomwe zimakwera ndi kutsika kwa ma pulses kapena mafunde awa zimakhala zachangu, nthawi zambiri zimakhala mu nanosecond kapena microsecond range. Mayeso amagetsi osinthasintha awa adapangidwa kuti ayerekezere ngozi zonse zamagetsi zomwe magalimoto angakumane nazo m'mikhalidwe yeniyeni, kuphatikizapo katundu wotayidwa. Kuonetsetsa kuti zida zomwe zili m'boti zikugwira ntchito bwino komanso chitetezo cha okwera.
Kuphatikiza piritsi lolimba logwirizana ndi ISO 7637-II m'galimoto kumapereka zabwino zambiri. Chofunika kwambiri, kulimba kwake kumatsimikizira kuti limagwira ntchito kwa nthawi yayitali komanso kuti limagwira ntchito bwino, kuchepetsa ndalama zokonzera ndikuwonjezera ntchito yonse. Chachiwiri, piritsi lolimba logwirizana ndi ISO 7637-II limapereka kuwonekera komanso kuwongolera zambiri zofunika nthawi yomweyo, kukonza bwino kuzindikira magalimoto ndikuwonjezera magwiridwe antchito. Pomaliza, mapiritsi awa amatha kulumikizana bwino ndi makina ena agalimoto ndi zida zakunja, kukulitsa kulumikizana ndi kugwirira ntchito limodzi. Mwa kutsatira muyezo uwu, titha kumanga kudalirika, kulimbikitsa kudalirana, ndikupereka zinthu zabwino kwambiri zomwe zimakwaniritsa zosowa za makasitomala.
Potsatira chitetezo cha ISO 7637-II standard transient voltage, mapiritsi olimba ochokera ku 3Rtablet amatha kupirira mpaka 174V 300ms vehicle surge attack ndikuthandizira DC8-36V wide voltage supply. Zimathandiza kwambiri kuti makina ofunikira kwambiri m'galimoto monga telematics, navigation interfaces ndi infotainment displays zikhale zolimba komanso kupewa kutayika komwe kumachitika chifukwa cha zolakwika.
