01 Qhov kev loj hlob ntawm lub zog tshiab tsav tsheb qhov kev thov hnyav ntawm kev ua lag luam OBC
Ua ib qho kev lag luam tseem ceeb hauv kuv lub teb chaws, kev lag luam tsheb fais fab tshiab tau txais txiaj ntsig zoo los ntawm tsoomfwv. Tsoomfwv tau tsim ntau txoj cai los txhawb thiab txhawb nqa kev txhim kho kev lag luam tsheb fais fab tshiab, uas tau ua lub luag haujlwm tseem ceeb hauv kev txhawb nqa kev txhim kho cov tsheb fais fab tshiab thiab cov khoom tseem ceeb.
Lub tshuab hluav taws xob fais fab ntawm cov tsheb fais fab tshiab feem ntau muaj peb ntu: lub tsheb fais fab on-board charger (AC-DC), inverter (DC-AC) thiab DC-DC converter. Lub on-board charger feem ntau siv hom ib-tsheb-ib-charger, thiab qhov nkag yog 220V AC. Raws li cov ntaub ntawv, qhov loj me ntawm kev lag luam ntawm kuv lub teb chaws OBC kev lag luam hauv xyoo 2022 yog kwv yees li 206.6 billion yuan, nce ntxiv txhua xyoo ntawm 95.6%.
Lub charger uas nyob hauv lub tsheb fais fab (OBC) yog hais txog lub charger uas tau teeb tsa ruaj khov rau ntawm lub tsheb fais fab, uas muaj peev xwm them lub roj teeb fais fab ntawm lub tsheb fais fab kom nyab xeeb thiab tsis tas yuav siv zog. Lub charger tuaj yeem hloov kho qhov tam sim no lossis qhov voltage raws li cov ntaub ntawv los ntawm lub kaw lus tswj roj teeb (BMS) muab, ua cov haujlwm sib xws, thiab ua tiav cov txheej txheem them.
Lub Charger Hauv Rooj Tsav Tsheb
02 Cov capacitors ib txwm muaj kev txwv txhua qhov chaw thiab daig hauv qhov teeb meem. Yuav ua li cas thiaj li tawg qhov teeb meem?
Tam sim no, cov tsheb fais fab tshiab tau dhau los ua ib qho teeb meem kub hauv kev lag luam tsheb thoob ntiaj teb. Txawm hais tias cov tsheb fais fab tshiab tau ua tiav zoo heev, tseem muaj ntau yam teeb meem uas yuav tsum tau daws, xws li kev ntxhov siab ntawm qhov deb, kev yooj yim them, kev them ceev, thiab lub sijhawm ntawm cov khoom siv ib txwm muaj thiab cov thev naus laus zis tshiab.
Lub hauv paus tseem ceeb ntawm kev daws teeb meem ntawm cov thev naus laus zis them ceev ceev OBC hauv lub tsheb yog yuav ua li cas kom nce lub zog them ntawm tag nrho lub tsheb. Txoj hauv kev los ua kom lub zog them yog yuav ua li cas kom nce lub zog hluav taws xob lossis tam sim no. Yog tias tam sim no nce ntxiv, nws yuav tsum hnyav dua. Tus nqi ntawm kev siv hluav taws xob ntau ntxiv thiab cov khoom siv pabcuam ntau dua yuav tsum tau siv. Yog li ntawd, cov chaw tsim khoom loj yuav tsiv los ntawm 400V voltage platform mus rau 800V lossis txawm tias siab dua voltage platform.
Txawm li cas los xij, cov txheej txheem no tso tawm cov kev xav tau hluav taws xob siab heev rau cov khoom siv hluav taws xob ib txwm muaj, tshwj xeeb tshaj yog cov capacitors DC bus. Vim yog qhov hluav taws xob tso zis siab ntawm lub zog hluav taws xob siab, cov capacitors ib txwm muaj feem ntau tsuas yog tiv taus cov hluav taws xob qis dua. Cov khoom siv dielectric hauv lub capacitor yuav raug puas tsuaj thaum muaj hluav taws xob siab, ua rau tawg. Yog tias lub capacitor bus tsis tuaj yeem tiv taus hluav taws xob txaus, nws yooj yim kom muaj kev tawg, hlawv tawm thiab lwm yam kev ua yuam kev, cuam tshuam rau kev ua haujlwm ib txwm ntawm tag nrho lub cev.
Yuav kom daws tau cov teeb meem hauv cov ntawv thov them fais tam sim no, YMIN snap-in aluminium electrolytic capacitors tau tsim ob cov khoom tshiab: CW3H thiab CW6H los ua kom tau raws li cov teeb meem hauv cov ntawv thov OBC thiab ua kom tau raws li cov kev xav tau ntawm ntau lub khw sib txawv.
03 Daws cov teeb meem qub thiab ua kom tau raws li cov kev xav tau tshiab, YMIN yeej ib txwm nyob ntawm txoj kev
Piv nrog cov capacitors ib txwm muaj, YMIN snap-in aluminium electrolytic capacitors muaj qhov tsis kam hluav taws xob siab dua thiab tuaj yeem ua haujlwm hauv qhov kub thiab txias, siab siab thiab qhov chaw siab, txhim kho kev ntseeg siab ntawm lub kaw lus, thiab txo qhov kev pheej hmoo ntawm kev ua tsis tiav xws li kev tawg thiab hlawv; ESR qis dua tuaj yeem muab cov zis tam sim no ntau dua thiab du dua rau OBC on-board; qhov kub qis dua, los ntawm kev tsim qauv tshwj xeeb ntawm Yongming capacitors thiab lub kaw lus cua sov dissipation, tuaj yeem txo qhov kub thiab txias sab hauv ntawm cov khoom, thiab tuaj yeem ua haujlwm ruaj khov hauv qab cov xwm txheej ua haujlwm nyuaj heev.
Cov khoom siv hluav taws xob YMIN snap-in aluminium electrolytic tsis yog tsuas yog muaj lub zog ceev ceev thiab cov qauv tshwj xeeb thiab cov khoom siv tsim, tab sis kuj muaj lub neej ua haujlwm ntev dua, uas tso cai rau cov neeg siv siv lub charger ntev dua. Tsis tas li ntawd, cov khoom tau raug kuaj xyuas thiab ntawv pov thawj nruj me ntsis, nws lub neej thiab kev ntseeg tau lav, thiab nws tau qhia txog cov txiaj ntsig zoo ntawm cov khoom hauv kev sim tshuab tiag tiag ntawm tus neeg siv khoom, thiab nws cov kev ua tau zoo kev nyab xeeb kuj zoo dua. Nws yog qhov tsim nyog heev rau kev siv hauv cov tsheb fais fab tshiab thiab lwm qhov chaw.
| Cov kua Snap hauv Aluminium Electrolytic Capacitor | Cov koob | Volt | Peev Xwm | Kub | Lub neej ntev |
| CW3H | 350~600V | 120~560uF | -40 ~ + 105 ℃ | 3000H | |
| CW6H | 400~600V | 120~470uF | -40 ~ + 105 ℃ | 6000H |
Nrog rau kev nthuav dav ntawm kev lag luam tsheb fais fab tshiab, cov thev naus laus zis on-board charger kuj tseem niaj hnub hloov kho thiab txhim kho. Raws li cov khoom tshiab, YMIN snap hauv aluminium electrolytic capacitors tau ua lub luag haujlwm tseem ceeb hauv kev txhim kho qib kev siv tshuab ntawm on-board chargers. Peb ntseeg tias nrog kev nce qib tas mus li thiab kev loj hlob ntawm ntau yam thev naus laus zis on-board OBC, kev koom tes ze ntawm kev sib phim siab, kev ntseeg siab siab, thiab lub neej ntev high-voltage kua horn capacitors, qhov kev them nqi ntawm on-board chargers yuav siab dua thiab siab dua, thiab qhov ceev them yuav sai dua thiab sai dua!
