Izibonisi zobushushu ze-NTC zidlala indima ebalulekileyo ekuqinisekiseni ukhuseleko kwiimfumba zokutshaja kunye nokutshaja imipu. Ngokuqhelekileyo zisetyenziselwa ukujonga ubushushu bexesha langempela kunye nokukhusela izixhobo ezigqithisiweyo, ngaloo ndlela zikhusela ukhuseleko kunye nokuthembeka kwenkqubo yokutshaja. Ngezantsi luhlalutyo lwezicelo zabo ezithile kunye nemisebenzi:
1. Iimeko zesicelo
(1) Ukujongwa koBuqondo kwimipu yokuTjaja
- Indawo yoQhakamshelwano kunye noHlolo oluDityanisiweyo lweCable:Ngexesha lokusebenza kwamandla aphezulu (umzekelo, ukutshaja ngokukhawuleza kwe-DC), imisinga emikhulu inokuvelisa ubushushu obugqithisileyo kwiindawo zoqhagamshelwano okanye iintambo zentambo ngenxa yokumelana noqhagamshelwano. Iinzwa ze-NTC ezifakwe kwintloko yompu okanye izihlanganisi zijonga utshintsho lobushushu ngexesha lokwenyani.
- Ukhuseleko lobushushu obugqithisileyo:Xa amaqondo obushushu edlula i-preset thresholds, isixokelelwano solawulo lokutshaja ngokuzenzekelayo sinciphisa ngoku okanye simisa ukutshaja ukuthintela iingozi zomlilo okanye umonakalo wesixhobo.
- Ukhuseleko lomsebenzisi:Ikhusela umphezulu wompu otshajayo ekutshiseni ngokugqithisileyo, ukuthintela ukutsha komsebenzisi.
(2) Ulawulo lobushushu ngaphakathi kweePili zokuTjaja
- IModyuli yaMandla yokuJonga iThermal:Iimodyuli zamandla aphezulu (umzekelo, iziguquli ze-AC-DC, iimodyuli ze-DC-DC) zivelisa ubushushu ngexesha lokusebenza. Izinzwa ze-NTC zibeka esweni ii-heatsinks okanye izinto ezibalulekileyo, ezibangela abalandeli bokupholisa okanye ukulungelelanisa ukuphuma kwamandla.
- Ukuziqhelanisa nokusiNgqongileyo:Iimfumba zokutshaja ngaphandle kufuneka zimelane namaqondo obushushu agqithisileyo. Abenzi boluvo be-NTC banceda ukongeza iiparamitha zokutshaja ngokusekwe kwiimeko ze-ambient (umzekelo, ukufudumeza kwebhetri kwangaphambili ebusika obubandayo).
2. Izinto eziluncedo ezingundoqo ze-NTC Sensors
- Uvakalelo oluPhezulu:Ukuchasana kwe-NTC kutshintsha kakhulu ngeqondo lokushisa, okwenza kube lula ukuphendula ngokukhawuleza kwiinguqu ezincinci.
- Ubungakanani obubambeneyo kunye nexabiso eliphantsi:Ilungele ukudityaniswa kwimipu yokutshaja edibeneyo kunye neemfumba, ezinikezela ngeendleko ezifanelekileyo.
- Uzinzo kunye noZinzo:Izixhobo zokufaka i-encapsulation (umzekelo, i-epoxy resin, iglasi) zibonelela ngokuthintela amanzi kunye nokuxhathisa ukubola, ezifanelekileyo kwiindawo ezinzima.
3. Iingqwalasela ezingundoqo zoYilo
- Indawo eNgcono:Izivamvo kufuneka zibekwe kufutshane nemithombo yobushushu (umz., ukutshaja abafowunelwa bompu, iimodyuli ze-IGBT kwiimfumba) ngelixa unqanda ukuphazamiseka kombane.
- Ulungelelwaniso loBuqondo kunye nolungelelwaniso:Iimpawu ze-NTC ezingezizo zifuna imbuyekezo ngeesekethe (umzekelo, izahluli zombane) okanye iialgorithms zesoftware (iitafile zokujonga, iSteinhart-Hart equation).
- Uyilo oluNgafunekiyo:Ukhuseleko oluphezulu lwezicelo lunokusebenzisa abenzi boluvo abaninzi be-NTC ukuqinisekisa ukusilela kwenqaku elinye akubeki engozini ukhuseleko.
- IiNdlela zoNxibelelwano kunye neeMpendulo:Idatha yobushushu ihanjiswa ngebhasi ye-CAN okanye imiqondiso ye-analog kwiNkqubo yoLawulo lweBattery (BMS) okanye isilawuli sokutshaja, okubangela iiprothokholi zokhuseleko ezikumgangatho ophezulu (umz., ukunciphisa amandla → ii-alam → ukuvala).
4. ImiGangatho yoShishino kunye nemingeni
- Iziqinisekiso zoKhuseleko:Ukuthotyelwa kwemigangatho efana ne-IEC 62196 kunye ne-UL 2251 yeemfuno zokubeka iliso lobushushu.
- Imingeni yeMeko eBabekileyo:Ukuzinza kumaqondo obushushu angaphezulu kwe-120°C okanye ngaphantsi kwe-40°C kufuna ukuqhubela phambili kwezinto (umzekelo, ifilimu eshinyeneyo ye-NTC).
- Uxilongo lweFault:Iisistim kufuneka zibone ukusilela kwe-NTC (umzekelo, iisekethe ezivulekileyo) ukunqanda izinto ezibangela ukhuseleko lobuxoki.
5. IiNdlela zekamva
- Uhlanganiso oluhlakaniphile:Ukudibanisa ne-AI algorithms ukwenzela ukugcinwa kwangaphambili (umzekelo, ukuqikelela ukuthotywa koqhagamshelwano ngedatha yembali).
- Iimeko zaMandla aphezulu:Njengoko ukutshaja okukhawulezileyo (350kW+) kuya kuxhaphaka, ii-NTC kufuneka ziphucule isantya sokuphendula kunye nokumelana nobushushu obuphezulu.
- Izisombululo ezizezinye:Ezinye izicelo zinokuthatha i-PT100 okanye i-infrared sensors, kodwa ii-NTC zihlala zilawula ngenxa yeendleko-zokusebenza.
Ukuqukumbela
Izinzwa zobushushu ze-NTC ziyinxalenye ebalulekileyo kwikhonkco lokhuseleko lweziseko ezingundoqo zokutshaja i-EV. Ngokubeka iliso ngexesha lokwenyani kunye neendlela zokuphendula ngokukhawuleza, bathomalalisa ngempumelelo imingcipheko yokutshisa kakhulu ngelixa bephucula ukusebenza kakuhle. Njengoko amandla okutshaja e-EV eqhubeka nokunyuka, ukuqhubela phambili kokuchaneka kwe-NTC, ukuthembeka, kunye nobukrelekrele kuya kubaluleka ekuxhaseni ukukhula koshishino.
