HV Heater Functional Control Txoj Cai
Taw qhia
The electric High Voltage Heater (HVH) is the best heating system for plug-in hybrids (PHEV) and battery electric vehicles (BEV). Nws converts DC fais fab mov mus rau hauv tshav kub nrog xyaum tsis poob.
Muaj hwj chim zoo ib yam li nws lub npe, lub tshuab hluav taws xob high-voltage no tshwj xeeb rau cov tsheb fais fab. Los ntawm kev hloov hluav taws xob hluav taws xob ntawm lub roj teeb nrog DC voltage, xws li 300 txog 750v, rau hauv cov cua kub ntau, cov cuab yeej no muab kev ua haujlwm zoo, xoom-emissions sov-txhua yam thoob plaws hauv lub tsheb.
Lub luag haujlwm tseem ceeb ntawm kev sib xyaw ua ke ntawm cov dej kub cua sov yog:
-Control muaj nuj nqi: Lub rhaub tswj hom yog lub hwj chim tswj thiab kub tswj;
- Cua sov muaj nuj nqi: hluav taws xob hloov mus rau thermal zog;
-Interface muaj nuj nqi: Cua sov module thiab tswj module zog tawm tswv yim, teeb liab module input, grounding, dej inlet thiab dej qhov hluav taws xob.
Txoj Cai Tswjfwm Kev Ua Haujlwm
Pib mos
PTC muab faib ua 3 pawg, thiab lub zog faib yog 5/10, 3/10, 2/10. PWM soft start mode, pab pawg muag muag, txhua pab pawg pib nyob rau hauv ib theem zuj zus, staggering lub ncov ntawm lub inrush tam sim no. Muaj 3 pawg ntawm IGBTs sab hauv, lub sijhawm ncua ntawm txhua pab pawg yog 8-10S, thiab qhov pib muag tau tiav
hauv 30 vib nas this.
Daim duab saum toj no yog daim duab qhia kev hloov pauv tam sim no muag muag
Lub zog thiab kub tswj
Tom qab qhov muag pib ua tiav, lub zog hloov kho raws li lub iav yuav tsum; thaum lub teeb kub tau mus txog, lub hwj chim tau hloov kho thiab tswj qhov kub thiab txias. Feem ntau, lub neej ntawd yog hom iav, uas tuaj yeem muab faib ua rau lub zog: 20 feem pua, 30 feem pua, 50 feem pua, 70 feem pua, 80 feem pua, thiab
100 feem pua. Yog tias PWM hom tau txais kev pom zoo, kev tswj hwm lub zog tsis muaj kev tswj hwm. Nco tseg: Kev siv PWM hom yuav tsum tau sib tham ua ntej.
