Ndi chitukuko chokhazikika chamakono cha magalimoto amagetsi, akatswiri ambiri ndi ogwiritsa ntchito akuyang'anitsitsa kwambiri chitetezo chamagetsi chamagetsi amagetsi, makamaka tsopano kuti ma voltages apamwamba (800V ndi pamwamba) akugwiritsidwa ntchito mosalekeza.Monga imodzi mwa njira zowonetsetsa kuti magalimoto amagetsi amagetsi akukwera kwambiri, ntchito ya high voltage interlock (HVIL) yakhala ikugogomezera kwambiri, ndipo kukhazikika ndi kuyankha kwachangu kwa HVIL kumapitilizidwa bwino.
High Voltage Interlock(HVIL mwachidule), ndi njira yopangira chitetezo kuti muzitha kuyang'anira mabwalo apamwamba kwambiri okhala ndi ma siginecha otsika.Popanga makina apamwamba kwambiri, kuti mupewe arc yomwe imayambitsidwa ndi cholumikizira champhamvu kwambiri pakugwira ntchito kwenikweni kwa njira yolumikizira magetsi, ndi kutseka, cholumikizira champhamvu kwambiri chimayenera kukhala ndi "high-voltage interlock" ntchito.
Dongosolo lolumikizira ma voltage apamwamba kwambiri lomwe lili ndi mphamvu zolumikizirana kwambiri, mphamvu, ndi ma terminals olowera akuyenera kukwaniritsa izi polumikiza ndikudula:
Pamene njira yolumikizira yamagetsi ikuluikulu imalumikizidwa, ma terminals amagetsi amalumikizidwa koyamba ndipo zolumikizira zolumikizira zimalumikizidwa pambuyo pake;pamene njira yolumikizira yamagetsi yamagetsi imachotsedwa, ma terminals olumikizana amachotsedwa poyamba ndipo ma terminals amagetsi amachotsedwa pambuyo pake.Ndiko kunena kuti:materminals okwera kwambiri ndi otalikirapo kuposa otsika voteji interlock terminals, zomwe zimatsimikizira kugwira ntchito kwa kuzindikirika kwa ma siginecha apamwamba kwambiri.
Ma interlocks okwera kwambiri amagwiritsidwa ntchito m'mabwalo amagetsi othamanga kwambiri, monga zolumikizira zamphamvu kwambiri, ma MSD, mabokosi ogawa ma voltage apamwamba, ndi mabwalo ena.Zolumikizira zokhala ndi zolumikizira zamphamvu kwambiri zimatha kulumikizidwa ndi nthawi yolumikizirana yamagetsi apamwamba kwambiri pomwe kutsegulira kumachitidwa pansi pamagetsi, ndipo nthawi yodulira ikugwirizana ndi kukula kwa kusiyana pakati pa kutalika kolumikizana kwamphamvu kwamphamvu yamagetsi. ma terminals ndi ma terminals amagetsi komanso kuthamanga kwa kulumikizidwa.Nthawi zambiri, nthawi yoyankhira dongosolo kudera lotsekeka lotsekeka limakhala pakati pa 10 ~ 100ms pomwe nthawi yolekanitsa yolumikizira (unplugging) imakhala yocheperako nthawi yoyankha, padzakhala chiwopsezo chachitetezo cha plugging yamagetsi ndi kutsitsa, ndi Kutsegula kwachiwiri kumapangidwira kuthetsa vuto la nthawi yotsekera iyi, kawirikawiri, kutsegulira kwachiwiri kungathe kulamulira bwino nthawi iyi yotsegula yoposa 1s, kuonetsetsa chitetezo cha ntchito.
Kutulutsa, kulandila, ndi kutsimikiza kwa siginecha yolumikizira zonse zimazindikirika kudzera mwa woyang'anira batri (kapena VCU).Ngati pali vuto lalikulu lamagetsi, galimotoyo siyiloledwa kuyenda pamagetsi okwera kwambiri, ndipo mabwalo olumikizirana amitundu yosiyanasiyana amasiyana (kuphatikiza kusiyana kwa mapini olumikizirana ndi mbali zamphamvu kwambiri zomwe zimaphatikizidwa ndi cholumikizira. ).
Chithunzi pamwambapa chikuwonetsa cholumikizira cholimba, pogwiritsa ntchito cholumikizira cholumikizira cholumikizira cholumikizira kuchokera ku cholumikizira chilichonse champhamvu chamagetsi chamtundu uliwonse kuti apange gawo lolumikizirana, pomwe gawo lamphamvu kwambiri lamagetsi limalephera kulumikiza, chipangizo chowunikira cholumikizira nthawi yomweyo nenani ku VCU, yomwe idzagwiritse ntchito njira yochepetsera mphamvu.Komabe, tisaiwale kuti sitingathe kulola galimoto yothamanga kwambiri kutaya mphamvu mwadzidzidzi, kotero liwiro la galimoto liyenera kuganiziridwa pakuchita njira yochepetsera mphamvu, kotero kuti zolumikizira zolimba ziyenera kukhala. grade pamene ndondomeko ikukonzedwa.
Mwachitsanzo, BMS, RESS (battery system), ndi OBC amaikidwa ngati level 1, MCU ndi MOTOR (electric motor) monga level 2, ndi EACP (electric air conditioning compressor), PTC, ndi DC/DC monga level 3.
Njira zosiyanasiyana za HVIL zimatengera magawo osiyanasiyana olumikizana.
Popeza zida zamphamvu kwambiri zimagawidwa m'galimoto yonse, izi zimapangitsa kuti pakhale nthawi yayitali kwambiri yolumikizirana, zomwe zimapangitsa kuti ma waya ovuta komanso mtengo wokwera wa ma waya otsika kwambiri.Komabe, njira yolumikizirana ndi hardwire ndi yosinthika pamapangidwe, osavuta pamaganizidwe, mwachilengedwe kwambiri, komanso amathandizira chitukuko.
