Pakuchulukirachulukira kwa magalimoto onyamula anthu komanso magalimoto ogulitsa, zida zamagetsi zamagalimoto zimagwiritsidwa ntchito kwambiri pamagalimoto. Pofuna kuwonetsetsa kuti zida zamagetsi izi zikuyenda bwino pamakina okhazikika amagetsi, ndikofunikira kuthana ndi vuto la kusokoneza kwakukulu kwamagetsi komwe kumapangidwa ndi magalimoto panthawi yogwira ntchito, yomwe imafalikira kumagetsi opangira magetsi kudzera pakuphatikiza, kuwongolera, ndi ma radiation, kusokoneza magwiridwe antchito a zida zapa board. Chifukwa chake, muyezo wapadziko lonse lapansi wa ISO 7637 wayika patsogolo zofunikira zachitetezo chazinthu zamagetsi zamagalimoto pamagetsi.
Muyezo wa ISO 7637, womwe umadziwikanso kuti: Magalimoto apamsewu-Kusokoneza kwamagetsi kopangidwa ndi conduction ndi kulumikizana, ndi mulingo wofananira wamagetsi wamagalimoto a 12V ndi 24V magetsi. Zimaphatikizanso kupirira kwa ma elekitiroma komanso magawo otulutsa poyesa kufananiza kwamagetsi. Miyezo yonseyi imatchula zofunikira pazida ndi zida zomwe zingagwiritsidwe ntchito kupanganso ngozi zamagetsi ndikuyesa mayeso. Kuyambira lero, muyezo wa ISO 7637 watulutsidwa m'magawo anayi. Pofika lero, muyezo wa ISO 7637 watulutsidwa m'magawo anayi kuwonetsa njira zoyesera ndi magawo okhudzana nawo mokwanira. Kenako tiwonetsa gawo lachiwiri la muyezo uwu, ISO 7637-II, lomwe limagwiritsidwa ntchito kuyesa kugwirizana kwa piritsi lathu lolimba.
ISO 7637-II imayitanitsa ma conduction amagetsi osakhalitsa m'mizere yoperekera kokha. Imatchulanso mayeso a benchi poyesa kuphatikizika kwa zida zamagetsi zomwe zimayikidwa pamagalimoto onyamula anthu ndi magalimoto opepuka amalonda okhala ndi makina amagetsi a 12 V kapena magalimoto amalonda okhala ndi magetsi a 24 V - pa jakisoni komanso kuyeza kwanthawi yochepa. Kulephera kwamtundu wa kuopsa kwa chitetezo chamthupi kumaperekedwanso. Imagwiritsidwa ntchito pamitundu iyi yamagalimoto apamsewu, osadalira makina oyendetsa (mwachitsanzo, kuyatsa kapena injini ya dizilo, kapena mota yamagetsi).
Kuyesa kwa ISO 7637-II kumaphatikizapo ma waveform osiyanasiyana osakhalitsa. Mphepete zokwera ndi zotsika za ma pulse kapena ma waveform awa ndi othamanga, nthawi zambiri amakhala mu nanosecond kapena microsecond. Kuyesera kwamagetsi kwakanthawi kumeneku kudapangidwa kuti kuyerekezere ngozi zonse zamagetsi zomwe magalimoto angakumane nazo pansi pa zochitika zenizeni, kuphatikizapo kutaya katundu. Kuwonetsetsa kuti zida zomwe zili m'bwalo zikuyenda mokhazikika komanso chitetezo cha okwera.
Kuphatikiza piritsi lolimba la ISO 7637-II m'galimoto kumapereka zabwino zambiri. Choyambirira, kukhazikika kwawo kumatsimikizira kugwira ntchito kwanthawi yayitali komanso magwiridwe antchito odalirika, kuchepetsa ndalama zolipirira ndikuwonjezera zokolola zonse. Chachiwiri, piritsi lolimba la ISO 7637-II limapereka mawonekedwe enieni komanso kuwongolera zidziwitso zofunikira, kuwongolera zowunikira zamagalimoto ndikuwonjezera magwiridwe antchito. Pomaliza, mapiritsiwa amatha kulumikizana mosasunthika ndi machitidwe ena agalimoto ndi zida zakunja, kukulitsa kulumikizana ndi kugwirizana. Potsatira muyezo umenewu, tikhoza kukhala odalirika, kulimbikitsa chikhulupiriro, ndi kupereka zinthu zapamwamba zomwe zimakwaniritsa zofuna za makasitomala.
Mogwirizana ndi ISO 7637-II chitetezo chamagetsi osakhalitsa, mapiritsi olimba ochokera ku 3Rtablet amatha kupirira mpaka 174V 300ms kugunda kwagalimoto ndikuthandizira DC8-36V yamagetsi ambiri. Imawongolera kukhazikika kwa magwiridwe antchito ofunikira amgalimoto monga ma telematics, ma navigation interfaces ndi ma infotainment zowonetsera pansi pazovuta komanso kupewa kuwonongeka komwe kumachitika chifukwa cha kusokonekera.
