Lub tshuab faib hluav taws xob siab rau cov tsheb yog dab tsi?
Lub tshuab faib hluav taws xob siab (PDU) hauv tsheb yog ib qho tseem ceeb hauv lub tshuab hluav taws xob siab ntawm cov tsheb fais fab tshiab, feem ntau yog lub luag haujlwm rau kev faib hluav taws xob thiab kev tswj hwm kom ntseeg tau tias kev ua haujlwm zoo thiab ruaj khov ntawm cov khoom siv hluav taws xob siab ntawm lub tsheb.
Cov haujlwm tseem ceeb
Youdaoplaceholder0 Kev faib hluav taws xob thiab kev tswj hwm : Faib cov hluav taws xob siab ncaj qha mus rau ntau yam khoom siv hluav taws xob, xws li lub cev muaj zog tsav, lub tshuab them hluav taws xob, thiab lwm yam.
Youdaoplaceholder0 kev tswj hwm kev them thiab kev tso tawm: Tswj cov txheej txheem them thiab kev tso tawm ntawm lub kaw lus hluav taws xob siab, suav nrog kev tiv thaiv kev thauj khoom ntau dhau, kev tiv thaiv luv luv thiab kev ua haujlwm kuaj hluav taws xob siab.
Youdaoplaceholder0 kev tswj hwm qis-voltage : kev tswj hwm lub zog thiab kev saib xyuas qhov xwm txheej ntawm cov khoom siv hluav taws xob siab los ntawm cov voj voog qis-voltage.
Youdaoplaceholder0 tsim cua sov dissipation: Qee cov PDUs siv cov qauv dej txias lossis cua txias kom ntseeg tau tias cov khoom siv hluav taws xob siab xav tau cua sov dissipation.
Cov yam ntxwv ntawm cov qauv
Lub PDU tuaj yeem koom ua ke cov haujlwm xws li DC-DC hloov pauv modules, them OBC modules, thiab BMS lub ntsiab tswj, ua tiav kev tsim qauv sib koom ua ke. Piv txwv li, peb-hauv-ib thiab plaub-hauv-ib modules tuaj yeem koom ua ke ntau lub luag haujlwm kom tau raws li qhov xav tau ntawm cov qauv tsheb sib txawv.
Lub tshuab faib hluav taws xob siab (PDU) yog lub cuab yeej tswj hwm tseem ceeb ntawm lub tshuab hluav taws xob siab hauv cov tsheb fais fab tshiab, feem ntau ua tiav cov haujlwm ntawm kev faib hluav taws xob thiab kev tiv thaiv kev nyab xeeb. Cov hauv qab no yog nws cov haujlwm tseem ceeb:
Kev faib hluav taws xob siab
Lub PDU faib cov hluav taws xob siab-voltage ncaj qha (300-800V) tso tawm los ntawm lub roj teeb fais fab mus rau cov khoom tseem ceeb xws li lub cev muaj zog tsav, lub charger on-board (OBC), DC/DC converter, thiab lub tshuab cua txias hluav taws xob compressor. Piv txwv li, lub cev muaj zog tsav suav txog li 60% ntawm cov hluav taws xob tso tawm, nrog rau cov seem faib rau cov kab ke pabcuam xws li kev them thiab cua sov.
Txoj kev tiv thaiv kev nyab xeeb
Xws li overcurrent, luv luv Circuit Court, overvoltage thiab overheat tiv thaiv:
Youdaoplaceholder0 kev tiv thaiv overcurrent: Thaum tam sim no tshaj 120% ntawm tus nqi ntsuas rau 2 vib nas this, lub contactor tseem ceeb raug txiav tawm thiab lub fuse raug cua tshuab
Youdaoplaceholder0 Kev tiv thaiv luv luv: Thaum lub impedance qis dua 100mΩ, lub voj voog raug txiav tawm hauv microseconds
Youdaoplaceholder0 Kev tiv thaiv kub dhau: Thaum qhov kub ntawm lub tsheb tooj liab tshaj 110 ℃, nws yuav maj mam txo qhov hnyav lossis txiav lub zog
Youdaoplaceholder0 Kev kuaj pom kev rwb thaiv tsev: tuaj yeem txheeb xyuas qhov kev pheej hmoo ntawm kev ua tsis tiav rwb thaiv tsev <500Ω / V thiab ua rau lub tswb ceeb toom
Kev koom ua ke thiab kev tswj hwm ntawm lub kaw lus
Nws muab DC/DC hloov module, chav tswj them thiab BMS lub luag haujlwm tswj tseem ceeb, thiab txhawb nqa kev tsim qauv modular. Cov lus qhia VCU tau txais los ntawm CAN bus kom ua tiav qhov kev tswj hwm hluav taws xob ntawm lub voj voog hluav taws xob siab (lub sijhawm teb <50ms), thiab txoj kev faib hluav taws xob tau hloov kho dynamically (xws li kev txiav txim siab qhov tseem ceeb ntawm kev kaw cov khoom tsis tseem ceeb thaum lub sijhawm them).
Cov ntsuas kev ua tau zoo
Kev ua haujlwm ntawm kev faib tawm ≥98% (nyob rau hauv qhov ntsuas load)
Lub zog rwb thaiv tsev tuaj yeem tiv taus 2500V AC rau 60 vib nas this yam tsis muaj kev tawg
Lub neej kho tshuab ntawm lub relay hluav taws xob siab yog ntau tshaj 100,000 lub voj voog
Txhawb kev ua haujlwm sib phim thauj khoom hloov kho (txo kev siv hluav taws xob los ntawm 5-8%)
Qhov tsis zoo ntawm lub tshuab faib hluav taws xob siab ntawm lub tsheb feem ntau ua rau muaj cov kab ke fais fab tsis zoo, kev cuam tshuam kev them lossis kev puas tsuaj rau cov khoom siv hluav taws xob, uas tau pom tseeb tias yog:
Qhov teeb meem ntawm qhov yuam kev
Youdaoplaceholder0 Lub zog fais fab tsis ua haujlwm : Lub tsheb tsis tuaj yeem nrawm dua li qub, thiab qhov ceev tshaj plaws raug txwv (piv txwv li, qhov ceev hauv rooj plaub tsuas yog 40km / h)
Youdaoplaceholder0 Kev them nyiaj tsis zoo: AC/DC kev them nyiaj raug cuam tshuam lossis tsis tuaj yeem pib (tshawb xyuas seb puas muaj qhov tsis zoo hauv kab them nyiaj lossis lub sensor)
Youdaoplaceholder0 Lub tswb ceeb toom ntawm lub cuab yeej: Qhia cov lus qhia "Qhov teeb meem ntawm lub tshuab hluav taws xob siab" lossis "qhov teeb meem ntawm lub zog fais fab"
Youdaoplaceholder0 Kev tiv thaiv cov khoom siv hluav taws xob: Lub kaw lus txiav tawm lub voj voog hluav taws xob siab kom tiv thaiv kev puas tsuaj ntxiv (xws li cov tswj lub cev muaj zog, cov roj teeb fais fab, thiab lwm yam)
Cov laj thawj feem ntau
Youdaoplaceholder0 lub voj voog hluav taws xob siab qhib lub voj voog : cov teeb liab saib xyuas tsis zoo ua rau lub kaw lus xauv (xws li kev sib cuag kab tsis zoo, lub tshuab hluav taws xob tawg)
Qhov tsis zoo sab hauv ntawm lub thawv faib khoom: tus contactor ntawm lub thawv faib khoom hluav taws xob siab tau daig, thiab qhov kev kuaj pom qhov xau tsis ua haujlwm
Youdaoplaceholder0 Luv Circuit Court lossis overload : kev puas tsuaj rau txheej rwb thaiv tsev ntawm cov xov hluav taws xob siab ua rau luv Circuit Court rau hauv av
Cov txheej txheem kuaj mob
Youdaoplaceholder0 Nyeem cov lej ua txhaum cai: Tau txais cov lej ua txhaum cai tshwj xeeb (xws li P1E0300, B042900) los ntawm lub decoder
Youdaoplaceholder0 teeb liab waveform xeem : Saib xyuas seb lub voj voog ua haujlwm ntawm lub voj voog high-voltage interlock puas yog qhov qub (xav tau cov khoom siv tshaj lij)
Youdaoplaceholder0 kev kuaj xyuas lub voj voog : Saib xyuas cov lus teb ntawm cov khoom siv hluav taws xob (xws li lub zog fais fab ntawm lub tshuab tswj lub cev muaj zog) hauv cov xwm txheej ua txhaum simulated
Nws raug pom zoo kom hu rau lub koom haum saib xyuas kev tshaj lij rau kev sim cov hluav taws xob siab kom tsis txhob muaj kev phom sij rau kev nyab xeeb los ntawm kev rhuav tshem tus kheej.
