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

Ngokuthuthukiswa okuqhubekayo kwamanje kwezimoto zikagesi, ochwepheshe abaningi nabasebenzisi baya ngokuya benaka ukuphepha kwamandla kagesi aphezulu, 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 yoxhumano lwamandla kagesi aphezulu anomsebenzi wokuvala amandla kagesi aphezulu, amandla, namatheminali axhumene kufanele ahlangabezane nalezi zimo ezilandelayo lapho uxhuma futhi unqanyulwa:

 

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.

 Isimiso sesakhiwo sokuxhumanisa i-voltage ephezulu

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 okwesibili kuklanyelwe ukuxazulula inkinga yalesi sikhathi sokunqanyulwa, ngokuvamile, ukuvula kwesibili kungalawula ngempumelelo lesi sikhathi sokunqanyulwa esingaphezu kwama-1s, ukuqinisekisa ukuphepha kocingo. ukusebenza.

 

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. ).

 I-high voltage interlock circuit

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.
