01 Txoj kev loj hlob ntawm lub zog tshiab tsav lub zog-core xav tau ntawm OBC kev ua lag luam
Raws li ib qho tseem ceeb ntawm kev lag luam tawm tswv yim hauv kuv lub teb chaws, kev lag luam tsheb tshiab lub zog tau ntev heev los ntawm tsoomfwv. Tsoomfwv tau tshaj tawm ntau txoj cai los txhawb thiab txhawb txoj kev loj hlob ntawm kev lag luam tsheb tshiab lub zog, uas tau ua lub luag haujlwm tseem ceeb hauv kev txhawb nqa kev loj hlob ntawm lub zog tshiab thiab cov khoom tseem ceeb.
Lub zog hluav taws xob hluav taws xob ntawm cov tsheb tshiab lub zog feem ntau suav nrog peb ntu: lub tsheb hluav taws xob hluav taws xob hauv lub nkoj (AC-DC), inverter (DC-AC) thiab DC-DC converter. Lub on-board charger feem ntau txais yuav ib-tsheb-ib-chaw them nqi hom, thiab cov tswv yim yog 220V AC. Raws li cov ntaub ntawv, kev lag luam loj ntawm kuv lub teb chaws OBC kev lag luam hauv 2022 yog kwv yees li 206.6 billion yuan, ib xyoos ib zaug nce ntawm 95.6%.
Lub on-board charger (OBC) yog hais txog lub charger fixedly ntsia rau ntawm lub tsheb fais fab, uas muaj peev xwm ua kom muaj kev nyab xeeb thiab cia li them lub hwj chim ntawm lub tsheb fais fab. Lub charger tuaj yeem hloov kho qhov ntsuas tam sim no lossis qhov ntsuas hluav taws xob raws li cov ntaub ntawv muab los ntawm lub roj teeb tswj kev tswj hwm (BMS), ua cov haujlwm sib xws, thiab ua tiav cov txheej txheem them nyiaj.

02 Ib txwm siv cov capacitors txwv txhua qhov chaw thiab daig hauv qhov teeb meem. Yuav ua li cas rhuav tshem qhov teeb meem?
Tam sim no, lub zog tshiab tsheb tau dhau los ua lub ntsiab lus kub hauv kev lag luam tsheb thoob ntiaj teb. Txawm hais tias lub zog tshiab tsheb tau ua tiav zoo, tseem muaj ntau yam teeb meem yuav tsum tau daws, xws li kev ntxhov siab ntau, kev them nyiaj yooj yim, them ceev ceev, thiab lub sij hawm ntawm cov khoom siv niaj hnub thiab cov thev naus laus zis tshiab.
Lub hauv paus tseem ceeb ntawm kev daws teeb meem ntawm on-board OBC ceev them thev naus laus zis yog yuav ua li cas txhawm rau txhawm rau them lub zog ntawm tag nrho lub tsheb. Txoj hauv kev los ua kom lub zog them nyiaj ntau dua yog yuav ua li cas kom nce qhov voltage lossis tam sim no. Yog tias qhov tam sim no nce, nws yuav tsum hnyav dua. Tus nqi ntawm kev siv hluav taws xob ntau ntxiv thiab cov cuab yeej pabcuam ntxiv yuav tsum tau siv. Yog li ntawd, cov tuam txhab lag luam loj yuav txav los ntawm 400V voltage platform mus rau 800V lossis ntau dua qhov hluav taws xob platform.
Txawm li cas los xij, cov txheej txheem no tso rau pem hauv ntej ultra-siab voltage yuav tsum tau rau cov khoom siv hluav taws xob ib txwm muaj, tshwj xeeb tshaj yog tsheb npav DC capacitor. Vim lub siab tso zis voltage ntawm high-voltage fais fab mov, tsoos capacitors feem ntau tsuas yog tiv taus qis voltages. Cov khoom siv dielectric hauv lub capacitor yuav raug puas tsuaj nyob rau hauv high voltage, uas ua rau puas. Yog hais tias lub tsheb npav capacitor tsis tuaj yeem tiv taus qhov hluav taws xob txaus, nws yog ib qho yooj yim kom muaj kev tawg, hlawv thiab lwm yam txhaum, cuam tshuam rau kev ua haujlwm ntawm tag nrho cov kab ke.
Txhawm rau daws cov teeb meem hauv daim ntawv thov tam sim no on-board charger, YMIN snap-in txhuas electrolytic capacitors tau tshaj tawm ob yam khoom tshiab: CW3H thiab CW6H kom tau raws li cov kev cov nyom hauv on-board OBC daim ntawv thov thiab ua tau raws li qhov xav tau ntawm kev lag luam sib txawv.
03 Kho cov ntsiab lus mob qub thiab ua tau raws li qhov xav tau tshiab, YMIN ib txwm nyob ntawm txoj kev
Piv nrog rau cov khoom siv ib txwm siv, YMIN snap-in aluminium electrolytic capacitors muaj qhov ua haujlwm siab dua thiab tuaj yeem ua haujlwm nyob rau hauv qhov kub thiab txias, kev kub siab thiab ntau zaus ib puag ncig, txhim kho kev ntseeg tau, thiab txo qhov kev pheej hmoo ntawm kev ua tsis tiav xws li kev tawg thiab hlawv; qis ESR tuaj yeem muab ntau dua tam sim no thiab smoother ripple tso zis rau on-board OBC; qis kub nce, los ntawm cov qauv tsim tshwj xeeb ntawm Yongming capacitors thiab cov khoom siv hluav taws xob ua kom sov, tuaj yeem txo qhov kub thiab txias ntawm cov khoom, thiab tuaj yeem ua haujlwm ruaj khov nyob rau hauv kev ua haujlwm nyuaj heev.
YMIN snap-in aluminium electrolytic cov khoom siv tsis tsuas yog muaj lub zog ceev thiab cov qauv tshwj xeeb thiab cov khoom tsim, tab sis kuj muaj lub neej ua haujlwm ntev, tso cai rau cov neeg siv siv lub charger ntev dua. Tsis tas li ntawd, cov khoom tau raug soj ntsuam nruj me ntsis thiab tau lees paub, nws lub neej thiab kev ntseeg tau tau lees paub, thiab nws tau qhia cov khoom zoo hauv cov neeg siv khoom siv lub tshuab sim tiag tiag, thiab nws txoj kev nyab xeeb kev ua haujlwm kuj zoo dua. Nws yog qhov tsim nyog rau siv nyob rau hauv lub zog tshiab lub tsheb chargers thiab lwm qhov chaw.
| Kua Snap nyob rau hauv Aluminium Electrolytic Capacitor | Series | Volt | Muaj peev xwm | Kub | Lub neej ntev |
| CW 3 H | 350-600V | 120 ~ 560uF | -40 ~ + 105 ℃ | 3000 H | |
| CW 6 H | 400-600V | 120 ~ 470uF | -40 ~ + 105 ℃ | 6000 H |
Nrog rau kev nthuav dav ntxiv ntawm kev lag luam tshiab lub zog tsheb, cov khoom siv hluav taws xob ntawm lub tshuab hluav taws xob tseem niaj hnub txhim kho thiab txhim kho. Raws li cov khoom lag luam tshiab, YMIN snap hauv txhuas electrolytic capacitors tau ua lub luag haujlwm tseem ceeb hauv kev txhim kho cov txheej txheem ntawm on-board chargers. Peb ntseeg hais tias nrog rau kev nce qib thiab kev loj hlob ntawm ntau yam on-board OBC thev naus laus zis, kev sib koom tes zoo ntawm kev sib tw siab, kev ntseeg siab, thiab lub neej ntev-voltage kua horn capacitors, kev them nyiaj ua haujlwm ntawm on-board chargers yuav dhau los ua. siab dua thiab siab dua, thiab kev them nqi yuav nrawm dua thiab nrawm dua!
