Cov chaw them nyiaj EV teeb tsa li cas?
Jun 25, 2023
Nrog rau txoj kev loj hlob ntawm lub zog tshiab kev lag luam, cov tsheb hluav taws xob tau dhau los ua ntau dua hauv lub neej. Automakers xws li BYD, BMW, thiab Tesla tau dov tawm tag nrho cov tsheb hluav taws xob, thaum lub tsheb hybrid muaj ntau dua. Txhawm rau kom tau yooj yim them cov roj teeb ntawm cov tsheb fais fab no, cov chaw them nqi yuav tsum tau tsim. Yuav ua li cas teeb tsa lub charger pawg? Cia peb saib sai sai.
Lub chaw nres tsheb hluav taws xob them hluav taws xob feem ntau yog tsim los ntawm peb ntu: cov khoom siv hluav taws xob, lub charger thiab kev saib xyuas.
Cov khoom siv hluav taws xob no tsuas yog muab lub zog rau lub charger, feem ntau yog tsim los ntawm cov cuab yeej tseem ceeb (switches, transformers, switching circuits, thiab lwm yam) thiab cov khoom siv thib ob (xws li kev tshawb nrhiav, kev tiv thaiv, kev tswj cov khoom, thiab lwm yam), thiab tshwj xeeb tshaj yog nruab nrog cov khoom siv lim dej. cov khoom siv los tshem tawm cov kev sib haum xeeb thiab ruaj khov ntawm daim phiaj hluav taws xob.
Lub charger yog lub hauv paus ntawm tag nrho cov khoom siv hluav taws xob, uas feem ntau muab faib ua pawg DC them thiab AC them pawg. Lub DC charging pawg, piv txwv li, off-board charger, enables ceev ceev them roj teeb. Lub AC them lub teeb feem ntau muab kev ua haujlwm maj mam them lub tsheb. Cov zis yog AC thiab yuav tsum txuas nrog lub charger built-in.
Kev saib xyuas tus xov tooj muaj ib lossis ntau lub chaw ua haujlwm lossis cov servers, suav nrog kev saib xyuas cov chaw ua haujlwm, cov ntaub ntawv servers, thiab lwm yam. Cov khoos phis tawj no txuas nrog lub network. Lub chaw saib xyuas chaw ua haujlwm muab qhov cuam tshuam rau tib neeg-khoos phis tawj kev sib tham them nyiaj saib xyuas kom paub saib xyuas thiab them cov ntaub ntawv tau txais thiab nug. Cov ntaub ntawv server khaws cov ntaub ntawv nyoos thiab cov ntaub ntawv txheeb xyuas cov ntaub ntawv ntawm tag nrho cov nqi them nqi, thiab muab cov ntaub ntawv kev pabcuam thiab lwm yam kev pabcuam.
Tom ntej no, peb yuav tsom mus rau lub tshuab hluav taws xob thiab cov khoom siv hluav taws xob (AC charging pawg thiab DC charging pawg).
Fais fab system standard xav tau
1. Kev xav tau ntawm lub zog
1) Cov pawg them nyiaj yuav tsum ua haujlwm ntawm qhov hluav taws xob ntawm 10 (20) KV.
2) AC rechargeable roj teeb pob yuav tsum ua haujlwm ntawm qhov hluav taws xob ntawm 380 V lossis 220 V
3) Lub DC them pawg yuav tsum ua haujlwm ntawm qhov hluav taws xob ntawm 380 V.
2. Fais fab kev xav tau
1) Qhov sib txawv ntawm qhov hluav taws xob ntawm lub zog hluav taws xob yuav tsum sib npaug ntawm qhov sib txawv ntawm qhov hluav taws xob ntawm 10 (20) kV, thiab tom qab peb theem hluav taws xob yuav tsum tsis pub tshaj ± 7 ntawm qhov ntsuas hluav taws xob. Qhov sib txawv voltage ntawm ib theem 220 V yuav tsum tsis pub tshaj 7 feem pua, -10 feem pua ntawm cov ntsuas hluav taws xob.
2) Qhov sib txawv zaus yuav tsum tsis pub tshaj ±0.2 Hz.
3) Lub harmonic voltage txwv ntawm daim phiaj siv hluav taws xob xav kom tag nrho cov kev sib haum xeeb ntawm qhov sib txawv ntawm 10 (20) kV peb-theem voltage tsawg dua 5 feem pua, thaum tag nrho cov harmonic distortion tus nqi ntawm 380V peb-theem voltage tsawg dua 4 feem pua. ;
4) Thaum khiav ntawm qhov siab tshaj plaws load, xyuas kom meej tias lub hwj chim ntawm 10 (20) KV sab ntawm lub transformer tsis tsawg dua 0.95.
