Ukusebenza kwe-voltage ephezulu ye-interlock kanye nendlela yokufeza imoto kagesi

Ngokuthuthukiswa okuqhubekayo kwamanje kwezimoto zikagesi, ochwepheshe abaningi nabasebenzisi baya ngokuya benaka ukuphepha kwe-high-voltage yezimoto zikagesi, ikakhulukazi manje njengoba ama-voltage aphezulu epulatifomu (800V nangaphezulu) asetshenziswa ngokuqhubekayo.Njengenye yezinyathelo zokuqinisekisa ukuphepha kukagesi ophezulu wezimoto zikagesi, umsebenzi we-high voltage interlock (HVIL) ugcizelelwe ngokwandayo, futhi ukuzinza nesivinini sokuphendula somsebenzi we-HVIL kuthuthukiswa ngokuqhubekayo.

I-High Voltage Interlock(i-HVIL ngamafuphi), iyindlela yokuklama ukuphepha yokuphatha amasekhethi kagesi aphezulu anamasignali kagesi aphansi.Ekuklanyweni kwesistimu ye-voltage ephezulu, ukugwema i-arc ebangelwa isixhumi se-voltage ephezulu ekusebenzeni kwangempela kwenqubo yokunqanyulwa kukagesi, nokuvala, isixhumi esinamandla kagesi kufanele sibe "ne-interlock ephezulu" umsebenzi.

Isistimu yokuxhuma i-high-voltage enomsebenzi wokuvala amandla kagesi aphezulu, amandla, namatheminali axhumene kufanele ihlangabezane nalezi zimo ezilandelayo lapho ixhuma futhi inqanyulwa:

Uma isistimu yokuxhuma i-high-voltage ixhunyiwe, amatheminali kagesi axhunyiwe kuqala futhi amatheminali ahlanganisiwe axhunywe kamuva;lapho uhlelo lokuxhuma lwamandla kagesi aphezulu lunqanyulwa, amatheminali axhumene ayanqanyulwa kuqala bese kuthi amatheminali kagesi anqanyulwe kamuva.Lokho kusho ukuthi:amatheminali kagesi aphezulu made kunamatheminali e-interlock kagesi aphansi, okuqinisekisa ukusebenza kahle kokutholwa kwesignali yokukhiya kwamandla kagesi aphezulu.

I-High-voltage interlocks ijwayele ukusetshenziswa kumasekhethi kagesi anamandla amakhulu, njengezixhumi ezinama-voltage aphezulu, ama-MSD, amabhokisi okusabalalisa amandla kagesi aphezulu, nezinye izifunda.Izixhumi ezinama-high-voltage interlock zinganqanyulwa isikhathi esinengqondo se-high-voltage interlock lapho ukuvulwa kwenziwa ngaphansi kwamandla, futhi isikhathi sokunqanyulwa sihlobene nosayizi womehluko phakathi kobude bokuxhumana obusebenzayo be-high-voltage interlock. amatheminali namatheminali amandla kanye nesivinini sokunqanyulwa.Imvamisa, isikhathi sokuphendula sohlelo kusekethe yetheminali ehlanganayo siphakathi kuka-10 ~ no-100ms lapho isikhathi sokuhlukaniswa kwesistimu yokuxhuma (ukuvula) singaphansi kwesikhathi sokuphendula sohlelo, kuzoba nengozi yokuphepha yokuxhunywa kukagesi nokukhipha i-plug, futhi ukuvula kwesibili kuklanyelwe ukuxazulula inkinga yalesi sikhathi sokunqanyulwa, ngokuvamile, ukuvula kwesibili kungalawula ngempumelelo lesi sikhathi sokunqanyulwa esingaphezu kwama-1s, ukuqinisekisa ukuphepha kokusebenza.

Ukukhishwa, ukwamukela, nokunqunywa kwesignali yokukhiya konke kwenziwa ngesiphathi sebhethri (noma i-VCU).Uma kunephutha le-high-voltage interlock, imoto ayivunyelwe ukuthi ihambe ngamandla kagesi aphezulu, futhi amasekhethi axhumayo amamodeli ezimoto ahlukene anomehluko othile (okuhlanganisa umehluko wamaphini okukhiya kanye nezingxenye zamandla kagesi aphezulu ezifakwe kusihluthulelo. ).

Lesi sibalo esingenhla sibonisa i-interlock enezintambo eziqinile, kusetshenziswa i-hardwire ukuxhuma amasignali empendulo kusukela kusixhumi ngasinye sengxenye ye-high-voltage ochungechungeni ukuze kwakhe isekethe ye-interlock, lapho ingxenye ye-voltage ephezulu kusekethe ihluleka ukuxhuma, idivayisi yokuqapha i-interlock izoba ngokushesha. bika ku-VCU, ezosebenzisa isu elihambisanayo lokwehlisa amandla.Kodwa-ke, kufanele kuqashelwe ukuthi asikwazi ukuvumela imoto enejubane elikhulu ilahlekelwe amandla ngokuzumayo, ngakho-ke ijubane lemoto kufanele licatshangelwe ekusetshenzisweni kwesu lokuhlehlisa amandla, ngakho-ke izintambo ezinezintambo eziqinile kufanele zibe. graded lapho isu lakhiwe.

Isibonelo, i-BMS, i-RESS (uhlelo lwebhethri), ne-OBC zihlukaniswa njengezinga loku-1, i-MCU ne-MOTOR (injini kagesi) njengeleveli 2, kanye ne-EACP (i-compressor air conditioning kagesi), i-PTC, ne-DC/DC njengeleveli 3.

Amasu ahlukene e-HVIL asetshenziswa kumazinga ahlukene axhumanayo.

Njengoba izingxenye ze-high-voltage zisakazwa kuyo yonke imoto, lokhu kuholela kubude obude be-interlock hardwire, okuholela ekufakweni kwezintambo eziyinkimbinkimbi kanye nezindleko ezikhulayo zamahhanisi ezintambo ezinama-voltage aphansi.Kodwa-ke, indlela ye-hardwire interlocking iyaguquguquka ekwakhiweni, ilula ku-logic, inembile kakhulu, futhi ikhuthaza ukukhula.
