Ukusetshenziswa kwezinzwa zokushisa ekushajani izinqwaba kanye nezibhamu zokushaja

Izinzwa zokushisa ze-NTC zidlala indima ebalulekile ekuqinisekiseni ukuphepha ekushajeni izinqwaba kanye nezibhamu zokushaja. Ngokuyinhloko zisetshenziselwa ukuqapha izinga lokushisa kwesikhathi sangempela nokuvimbela ukushisa ngokweqile kwemishini, ngaleyo ndlela kuvikelwe ukuphepha nokuthembeka kwenqubo yokushaja. Ngezansi ukuhlaziya kwezinhlelo zabo zokusebenza ezithile nemisebenzi:

1. Izimo Zokusebenza

(1) Ukuqapha Izinga lokushisa Ezimbanjeni zokushaja

• Indawo Yokuxhumana kanye Nokuqapha Okuhlangene Kwekhebula:Ngesikhathi sokusebenza kwamandla aphezulu (isb., ukushaja okusheshayo kwe-DC), imisinga emikhulu ingase ikhiqize ukushisa okudlulele ezindaweni okuxhunywana nazo noma amajoyinti ekhebula ngenxa yokumelana nokuxhumana. Izinzwa ze-NTC ezishumekwe ekhanda lesibhamu noma izixhumi ziqapha ukushintsha kwezinga lokushisa ngesikhathi sangempela.
• Ukuvikela ukushisa ngokweqile:Uma amazinga okushisa edlula imikhawulo ebekwe ngaphambilini, isistimu yokulawula ukushaja inciphisa ngokuzenzakalelayo ukushaja kwamanje noma ukumisa ukuvimbela izingozi zomlilo noma ukulimala kwempahla.
• Ukuphepha komsebenzisi:Ivimbela indawo yesibhamu esishajayo ekushiseni ngokweqile, igwema ukushiswa komsebenzisi.

(2) Ukuphathwa Kwezinga Lokushisa Ngaphakathi Kwezinqwaba Zokushaja

• Ukuqapha Okushisayo Kwemojuli Yamandla:Amamojula anamandla kagesi aphezulu (isb., iziguquli ze-AC-DC, amamojula e-DC-DC) akhiqiza ukushisa ngesikhathi sokusebenza. Izinzwa ze-NTC ziqapha ama-heatsink noma izingxenye ezibalulekile, ezicupha abalandeli bokupholisa noma ukulungisa ukuphuma kwamandla.
• Ukuguquguquka Kwemvelo:Izinqwaba zokushaja zangaphandle kufanele zimelane namazinga okushisa aphezulu. Izinzwa ze-NTC zisiza ukuthuthukisa amapharamitha wokushaja ngokususelwe kuzimo zendawo (isb., ukushisa amabhethri kusengaphambili ebusika obubandayo).

2. Izinzuzo Eziyinhloko Zezinzwa ze-NTC

• Ukuzwela Okuphezulu:Ukumelana ne-NTC kushintsha kakhulu ngezinga lokushisa, okuvumela ukusabela okusheshayo ekuguquguqukeni okuncane.
• Usayizi Ohlangene Nezindleko Eziphansi:Ilungele ukuhlanganiswa kuzibhamu ezishajayo ezihlangene kanye nezinqwaba, ezinikeza ukusebenza kahle kwezindleko.
• Ukuzinza Nokuqina:Izinto zokufaka i-encapsulation (isb., i-epoxy resin, ingilazi) ihlinzeka ngokuvikela amanzi kanye nokugqwala, okufanelekile ezindaweni ezinokhahlo.

3. Ukucatshangelwa Okubalulekile Kwedizayini

• Ukubekwa Okulungile:Izinzwa kufanele zibekwe eduze nemithombo yokushisa (isb., oxhumana nabo bezibhamu ezishajayo, amamojula e-IGBT enqwaba) kuyilapho kugwenywa ukuphazamiseka kukazibuthe.
• Ukulinganiswa Kwezinga Lokushisa Nokwenza Umugqa:Izici ze-NTC ezingaqondile zidinga isinxephezelo ngamasekhethi (isb, izihlukanisi zikagesi) noma ama-algorithms esofthiwe (amathebula okubheka, isibalo se-Steinhart-Hart).
• Idizayini Yokungafuneki:Izinhlelo zokusebenza zokuphepha okuphezulu zingasebenzisa izinzwa eziningi ze-NTC ukuqinisekisa ukuthi ukwehluleka kwephuzu elilodwa akufaki ukuphepha engozini.
• Izindlela Zokuxhumana Nezokuphendula:Idatha yezinga lokushisa idluliselwa ngebhasi le-CAN noma amasiginali e-analogi ku-Battery Management System (BMS) noma isilawuli sokushaja, okucupha izimiso eziyisisekelo zokuvikela (isb, ukuncishiswa kwamandla → ama-alamu → ukuvala shaqa).

4. Amazinga Nezinselele Zemboni

• Izitifiketi Zokuphepha:Ukuthobelana namazinga afana ne-IEC 62196 kanye ne-UL 2251 yezidingo zokuqapha izinga lokushisa.
• Izinselelo Zesimo Esikhulu:Ukuzinza emazingeni okushisa angaphezu kuka-120°C noma ngaphansi -40°C kudinga ukuthuthukiswa kwezinto ezibonakalayo (isb., ifilimu ewugqinsi i-NTC).
• I-Fault Diagnostics:Amasistimu kufanele athole ukwehluleka kwe-NTC (isb, amasekhethi avulekile) ukuze agweme izibangeli zokuvikela ezingamanga.

5. Amathrendi Akusasa

• Ukuhlanganisa Okuhlakaniphile:Ukuhlanganisa nama-algorithms e-AI okulungisa okubikezelwayo (isb, ukubikezela ukucekelwa phansi kothintana naye ngedatha yomlando).
• Izimo Ezinamandla Aphezulu:Njengoba ukushaja okushesha kakhulu (350kW+) kwanda, ama-NTC kufanele athuthukise isivinini sokuphendula kanye nokumelana nezinga lokushisa eliphezulu.
• Ezinye Izixazululo:Ezinye izinhlelo zokusebenza zingasebenzisa i-PT100 noma izinzwa ze-infrared, kodwa ama-NTC ahlala ekhona ngenxa yokusebenza kahle kwezindleko.

Isiphetho

Izinzwa zokushisa ze-NTC ziyingxenye ebalulekile ochungechungeni lokuphepha lwengqalasizinda yokushaja ye-EV. Ngokuqapha kwesikhathi sangempela kanye nezindlela zokuphendula ngokushesha, banciphisa ngempumelelo izingozi zokushisa ngokweqile ngenkathi bethuthukisa ukusebenza kahle. Njengoba amandla okushaja kwe-EV eqhubeka nokukhuphuka, ukuthuthuka kokunemba kwe-NTC, ukwethembeka, nobuhlakani kuzobaluleka ekusekeleni ukukhula kwemboni.
