Tsheb Charger (OBC)
Lub on-board charger yog lub luag hauj lwm rau converting alternating tam sim no rau direct tam sim no kom them lub hwj chim roj teeb.
Tam sim no, cov tsheb hluav taws xob qis qis thiab A00 mini hluav taws xob tsheb feem ntau yog nruab nrog 1.5kW thiab 2kW chargers, thiab ntau dua A00 cov neeg caij tsheb tau nruab nrog 3.3kW thiab 6.6kW chargers.
Feem ntau ntawm AC them cov tsheb lag luam siv 380v uaPeb-theem muaj hluav taws xob, thiab lub zog siab tshaj 10kW.
Raws li cov ntaub ntawv tshawb fawb ntawm Gaogong Electric Vehicle Research Institute (GGII), nyob rau xyoo 2018, qhov kev thov rau lub zog tshiab ntawm lub tsheb thauj khoom hauv Suav teb tau nce mus txog 1.220,700 teeb, nrog rau kev loj hlob ntawm 50.46%.
Los ntawm qhov kev xav ntawm nws cov qauv kev lag luam, chargers nrog cov zis hluav taws xob ntau dua 5kW tuav lub lag luam loj dua, txog 70%.
Lub tuam txhab txawv teb chaws tseem ceeb tsim lub tsheb charger yog Kesida,Emerson, Valeo, Infineon, Bosch thiab lwm yam lag luam thiab lwm yam.
Ib qho OBC feem ntau yog tsim los ntawm lub zog hluav taws xob (cov ntsiab lus tseem ceeb suav nrog PFC thiab DC / DC) thiab tswj Circuit Court (raws li qhia hauv qab no).
Ntawm lawv, lub luag haujlwm tseem ceeb ntawm lub zog hluav taws xob yog hloov pauv tam sim no mus rau qhov tam sim no ruaj khov;Kev tswj Circuit Court yog tsuas yog ua kom muaj kev sib txuas lus nrog lub roj teeb, thiab raws li qhov xav tau los tswj lub zog tsav hluav taws xob tso tawm ib qho voltage thiab tam sim no.
Diodes thiab hloov raj (IGBTs, MOSFETs, thiab lwm yam) yog cov khoom siv hluav taws xob tseem ceeb siv hauv OBC.
Nrog rau kev siv cov khoom siv hluav taws xob silicon carbide, kev hloov pauv ntawm OBC tuaj yeem ncav cuag 96%, thiab lub zog ceev tuaj yeem ncav cuag 1.2W / cc.
Kev ua tau zoo yuav tsum tau nce ntxiv mus rau 98% yav tom ntej.
Hom topology ntawm lub tsheb charger:
Cua txias thermal tswj
Nyob rau hauv lub tub yees system ntawm hluav taws xob tsheb cua txias, vim hais tias tsis muaj lub cav, lub compressor yuav tsum tau tsav los ntawm hluav taws xob, thiab scroll electric compressor integrated nrog tsav lub cev muaj zog thiab maub los yog dav siv nyob rau hauv tam sim no, uas muaj high volume efficiency thiab tsawg. nqi.
Kev nce siab yog qhov kev loj hlob tseem ceeb ntawmscroll compressors yav tom ntej.
Hluav taws xob tsheb cua txias cua sov yog qhov tsim nyog rau kev mloog.
Vim tias tsis muaj lub tshuab ua cua sov, cov tsheb hluav taws xob feem ntau siv PTC thermistor los ua kom sov lub cockpit.
Txawm hais tias qhov kev daws teeb meem no ceev ceev thiab tsis siv neeg qhov kub thiab txias, cov cuab yeej siv tau zoo dua, tab sis qhov tsis zoo yog tias lub zog siv hluav taws xob loj, tshwj xeeb tshaj yog nyob rau hauv qhov chaw txias thaum PTC cua sov tuaj yeem ua rau ntau tshaj 25% ntawm lub zog hluav taws xob.
Yog li ntawd, lub tshuab cua kub twj tso kua mis cua txias tau maj mam dhau los ua lwm txoj kev daws teeb meem, uas tuaj yeem txuag tau li ntawm 50% ntawm lub zog dua li PTC cov txheej txheem cua sov ntawm qhov ntsuas kub ntawm 0 ° C.
Hais txog cov tub yees, European Union's "Automotive Air Conditioning System Directive" tau txhawb kev txhim kho cov tub yees tshiab raucua txias, thiab daim ntawv thov ntawm ib puag ncig tus phooj ywg refrigerant CO2 (R744) nrog GWP 0 thiab ODP 1 tau maj mam nce.
Piv nrog HFO-1234yf, HFC-134a thiab lwm cov tub yees tsuas yog ntawm -5 degrees saum toj no muaj qhov ua kom txias zoo, CO2 ntawm -20 ℃ cua sov zog efficiency piv tseem tuaj yeem ncav cuag 2, yog lub neej yav tom ntej ntawm lub tsheb fais fab kub twj tso kua mis cua txias zog efficiency. yog qhov kev xaiv zoo tshaj plaws.

Nrog rau kev tsim hluav taws xob tsheb thiab kev txhim kho tus nqi ntawm kev tswj xyuas thermal, qhov chaw lag luam ntawm hluav taws xob tsheb thermal tswj yog dav.
