Puas yog nws ib txwm muaj rau lub plhaub thiab txoj hlua them hluav taws xob kub thaum lub sijhawm them, lossis nws puas yog qhov txaus ntshai rau kev nyab xeeb?

Nrog rau qhov nrov zuj zus ntawm cov tsheb fais fab tshiab,lub tsev ev chargerthiabchaw them roj rau pej xeemtau dhau los ua cov khoom siv uas peb siv txhua hnub. Ntau tus tswv tsheb ntsib qhov teeb meem no thaum them lub tsheb: "Lub phom them hluav taws xob kub thaum kov, thiab lub plhaub ntawm lub chaw them hluav taws xob kuj sov lossis kub heev. Qhov no puas yog ib txwm muaj?Tsab xov xwm no yuav muab kev tshuaj xyuas kev tshaj lij thiab kev txheeb xyuas dav dav ntawm qhov teeb meem no.

I. Xaus Lus: Kub Dhau ≠ Txaus Ntshai, tab sis Kub Dhau Yog Qhov Txaus Ntshai Zais Cia

Seb nws yogDC them ceev ceev or AC them qeeb, cov cables thiab cov connectors yuav tsim cov cua sov resistive nyob rau hauv high current. Ib yam li cov xov tooj chargers thiab laptop fais fab adapters, cua sov yog ib qho phenomenon, tsis yog functional.

Txawm li cas los xij, yog tias qhov kub nce siab tshaj qhov ntau thiab tsawg tsim nyog, nws qhia txog qhov teeb meem uas yuav tshwm sim: xws li thaj tsam tooj liab tsis txaus hauv cov xov hlau, cov pob qij txha tsis zoo, lossis lub qhov them hluav taws xob qub. Cov yam no tuaj yeem ua rau muaj cua sov sai sai, ua rau kub hnyiab, tawg, lossis txawm tias hluav taws.

II. Vim li cas cov khoom siv them hluav taws xob thiaj tsim cua sov?

Seb nws yog ib qhoChaw them hluav taws xob AClos yog ib qhoDC chaw them ceev ceev, ob qho tib si yuav tsum tau tswj hwm qhov tam sim no loj tas mus li thaum lub sijhawm ua haujlwm. Cov neeg coj hluav taws xob muaj kev tiv thaiv, thiab cua sov raug tsim thaum tam sim no ntws los ntawm lawv, raws li qhia hauv cov mis: P = I² × R

Thaum lub sijhawm them tam sim no ncav cuag 32A (Chaw them hluav taws xob hauv tsev 7kW) lossis txawm tias 200A ~ 500A (DC them ceev ceev Pile), txawm tias qhov kev tiv thaiv qis heev tuaj yeem tsim kom muaj cua sov ntau. Yog li ntawd, kev tsim cua sov nruab nrab yog ib qho xwm txheej ib txwm muaj thiab tsis poob rau hauv qeb ntawm kev ua haujlwm tsis zoo.

Cov chaw kub feem ntau muaj xws li:

1. Kev tiv thaiv cua sov ntawm cov xov hlau them lawv tus kheej
2. Kev sib cuag voltage poob ntawm lub taub hau them
3. Kev tshem tawm cua sov los ntawm cov khoom siv hluav taws xob sab hauv
4. Kub ntxiv los ntawm qhov kub thiab txias thiab lub hnub ci

Yog li ntawd, nws yog ib qho uas cov neeg siv feem ntau xav tias "sov so" lossis "kub me ntsis" thaum them.

III. Dab tsi yog qhov kub nce siab ib txwm muaj?

Cov qauv kev lag luam (xws li GB/T 20234, GB/T 18487, QC/T 29106) muaj cov kev cai tshwj xeeb rau qhov kub nce ntawmcov khoom siv them nqiFeem ntau hais lus:

1. Qhov ntau thiab tsawg ib txwm muaj
Qhov kub ntawm qhov chaw 40 ℃ ～ 55 ℃: Qhov kub nce li qub, muaj kev nyab xeeb siv.

55℃～70℃: Me ntsis siab tab sis tseem nyob hauv qhov txwv uas txais tau hauv ntau qhov xwm txheej, tshwj xeeb tshaj yog rau kev them hluav taws xob DC siab thaum lub caij ntuj sov.

2. Qhov ntau uas yuav tsum tau ceev faj

>70 ℃: Yuav luag lossis tshaj qhov ntsuas kub uas tso cai nce, yuav tsum nres kev them thiab kuaj xyuas lub cuab yeej.

Cov hauv qab no suav tias yog cov xwm txheej tsis zoo:

1. Ua kom cov roj hmab lossis yas mos
2. Tsw ntxhiab kub hnyiab
3. Cov xim ntawm cov hlau terminals ntawm lub taub hau them hluav taws xob ploj mus
4. Cov cheeb tsam ntawm qhov txuas yuav kub heev rau qhov kov lossis txawm tias tsis tuaj yeem kov tau.

Cov xwm txheej no feem ntau muaj feem cuam tshuam ncaj qha rau "kev tiv thaiv kev sib cuag tsis zoo" lossis "cov lus qhia tsis txaus ntawm cov xov hlau" thiab xav tau kev tshawb nrhiav tam sim ntawd.

IV. Yam dab tsi ua rau kub dhau?

1. Thaj tsam ntawm cov xov hlau tooj liab tsis txaus:Qee cov khoom tsis zoo siv cov xov hlau "tsis tseeb" nrog thaj tsam hlau tooj liab me dua, ua rau muaj kev tiv taus ntau dua thiab kub nce ntxiv.

2. Kev nce impedance ntawm cov plugs, terminals, thiab lwm qhov chaw sib cuag:Kev puas tsuaj los ntawm kev ntsaws thiab tshem tawm, kev txiav cov xov hlau tsis zoo, thiab kev plating tsis zoo tuaj yeem ua rau muaj kev tiv taus kev sib cuag, ua rau muaj qhov kub hauv zos. "Qhov kub ntawm lub connector tshaj qhov kub ntawm lub cable nws tus kheej" yog qhov tshwm sim feem ntau.

3. Kev tsim cov khoom siv hluav taws xob sab hauv tsis zoo:Piv txwv li, qhov tsis txaus cua sov hauv relays, contactors, thiab DC/DC modules yuav tshwm sim ua qhov kub siab los ntawm lub casing.

4. Kev cuam tshuam tseem ceeb ntawm cov yam ntxwv ib puag ncig:Kev them fais sab nraum zoov thaum lub caij ntuj sov, qhov kub hauv av siab, thiab tshav ntuj ncaj qha yuav ua rau qhov kub nce siab.

Cov yam no txiav txim siab qhovqhov sib txawv ntawm qhov zoo tiag tiag ntawm cov pawg them nqi, tshwj xeeb tshaj yog qhov kev ntseeg tau ntawm lub tuam txhab lub peev xwm R&D, kev xaiv cov khoom siv, thiab cov txheej txheem tsim khoom.

V. Yuav ua li cas thiaj paub seb puas muaj kev phom sij rau kev nyab xeeb?

Cov neeg siv tuaj yeem soj ntsuam qhov xwm txheej sai sai siv cov txheej txheem hauv qab no:

Cov xwm txheej ib txwm muaj:

• Lub phom them thiab lub plhaub sov so rau qhov kov.
• Tsis muaj ntxhiab tsw lossis deformation.
• Qhov kub hloov pauv ntau heev nrog rau qhov kub thiab txias ntawm ib puag ncig.

Cov xwm txheej tsis zoo:

• Muaj tej thaj chaw kub heev rau kov, txawm tias tsis kov los tau.
• Lub taub hau phom them hluav taws xob kub dua li lub xov hlau nws tus kheej.
• Nrog rau ntxhiab tsw kub hnyiab, suab nrov, lossis qee zaum cuam tshuam kev them nqi.
• Lub hau phom them fais fab mos lossis hloov xim.

Yog tias muaj qhov txawv txav tshwm sim, tsum tsis txhob siv lub cuab yeej tam sim ntawd thiab hu rau cov kev pabcuam tom qab muag lossis thov kom hloov pauv.

VI. Yuav xaiv qhov chaw them nqi li cas?

Chaw them fais fab rau tshebmuaj ntau yam kev ntsuas txog kev siv tshuab, suav nrog kev siv hluav taws xob ntau, kev nyab xeeb hluav taws xob, kev rwb thaiv hluav taws xob, thiab kev tswj qhov kub thiab txias, ua rau muaj kev xav tau ntau rau kev tshawb fawb thiab kev txhim kho thiab kev tsim khoom. Cov chaw tsim khoom lag luam muaj cov txiaj ntsig zoo hauv cov hauv qab no: cov lus qhia txog cable raug (tsis muaj cov ntsiab lus tooj liab cuav), cov taub hau them hluav taws xob muaj kev ntseeg siab thiab cov txheej txheem plating ntev, kev nce kub hnyav, kev laus, thiab kev sim ib puag ncig, kev saib xyuas kub thiab kev tiv thaiv, thiab lub kaw lus pov thawj kev nyab xeeb tiav nrog qhov zoo uas taug qab tau. Xaiv cov hom lag luam ua lag luam xws liTuam Tshoj Beihai Fais Fabua kom lawv cov khoom raug kuaj xyuas kev nyab xeeb hluav taws xob, kev kuaj xyuas kev laus, thiab kev txheeb xyuas qhov sib xws tag nrho, ua rau muaj kev ruaj khov thiab kev nyab xeeb ntau dua, thiab txo qhov kev pheej hmoo ntawm kev kub dhau thiab teeb meem sib cuag.
