Puas yog lithium hlau phosphate cell muaj kev nyab xeeb nyob rau hauv cov xwm txheej overcharge?,
roj teeb,

▍ Daim ntawv pov thawj CE yog dab tsi?

Lub cim CE yog "passport" rau cov khoom lag luam nkag mus rau EU kev lag luam thiab EU Free Trade Association lub teb chaws ua lag luam. Cov khoom lag luam uas tau teev tseg (suav nrog cov lus qhia tshiab), txawm tias tsim tawm sab nraud EU lossis hauv EU cov tswvcuab hauv lub tebchaws, txhawm rau txhawm rau nthuav dav hauv EU kev lag luam, lawv yuav tsum ua raws li cov cai ntawm cov lus qhia thiab cov qauv kev sib haum xeeb ua ntej. muab tso rau hauv EU ua lag luam, thiab affix CE cim. Qhov no yog qhov yuav tsum tau ua ntawm EU txoj cai lij choj ntawm cov khoom muaj feem xyuam, uas muab cov txheej txheem kev sib koom ua ke yam tsawg kawg nkaus rau kev lag luam ntawm ntau lub teb chaws hauv European kev ua lag luam thiab ua kom yooj yim cov txheej txheem kev lag luam.

▍ Cov lus qhia CE yog dab tsi?

Cov lus qhia yog ib daim ntawv pov thawj tsim los ntawm European Community Council thiab European Commission raws li kev tso cai ntawmEuropean Community Treaty. Cov lus qhia siv tau rau cov roj teeb yog:

2006/66 / EC & 2013/56 / EU: Roj Teeb Cov Lus Qhia. Cov roj teeb uas ua raws li cov lus qhia no yuav tsum muaj lub thoob khib nyiab pov tseg;

2014/30 / EU: Electromagnetic Compatibility Directive (EMC Cov Lus Qhia). Cov roj teeb uas ua raws li cov lus qhia no yuav tsum muaj CE cim;

2011/65 / EU: ROHS cov lus qhia. Cov roj teeb uas ua raws li cov lus qhia no yuav tsum muaj CE cim;

Cov Lus Qhia: Tsuas yog thaum cov khoom ua raws li tag nrho cov lus qhia CE (CE cim yuav tsum tau muab tso rau), tuaj yeem muab CE kos rau thaum tag nrho cov kev cai ntawm cov lus qhia tau ua tiav.

▍ Qhov Tseem Ceeb ntawm Kev Thov rau CE Certification

Txhua yam khoom los ntawm ntau lub teb chaws uas xav nkag mus rau EU thiab European Free Trade Zone yuav tsum thov rau CE-certified thiab CE cim rau ntawm cov khoom. Yog li, daim ntawv pov thawj CE yog daim ntawv hla tebchaws rau cov khoom nkag mus rau EU thiab European Free Trade Zone.

▍ Cov txiaj ntsig ntawm kev thov rau daim ntawv pov thawj CE

1. EU txoj cai lij choj, kev tswj hwm, thiab cov qauv kev sib koom tes tsis yog tsuas yog loj ntawm cov khoom, tab sis kuj nyuaj rau cov ntsiab lus. Yog li ntawd, tau txais daim ntawv pov thawj CE yog ib qho kev xaiv ntse heev kom txuag tau lub sijhawm thiab kev siv zog thiab txo qhov kev pheej hmoo;

2. Daim ntawv pov thawj CE tuaj yeem pab kom tau txais kev ntseeg siab ntawm cov neeg siv khoom thiab lub koom haum saib xyuas kev lag luam mus rau qhov siab tshaj plaws;

3. Nws tuaj yeem tiv thaiv qhov xwm txheej tsis lees paub;

4. Nyob rau hauv lub ntsej muag ntawm kev sib hais plaub, daim ntawv pov thawj CE yuav dhau los ua pov thawj raug cai;

5. Thaum raug txim los ntawm EU lub teb chaws, lub koom haum muab ntawv pov thawj yuav koom tes nrog cov kev pheej hmoo ntawm kev lag luam, yog li txo qhov kev pheej hmoo ntawm kev lag luam.

▍ Vim li cas MCM?

● MCM muaj ib pab neeg ua haujlwm nrog ntau tshaj 20 tus kws tshaj lij ua haujlwm hauv kev ua haujlwmroj teebCE daim ntawv pov thawj, uas muab cov neeg siv khoom sai dua thiab muaj tseeb dua thiab cov ntaub ntawv pov thawj CE tshiab kawg;

● MCM muab ntau yam kev daws teeb meem CE suav nrog LVD, EMC,roj teebcov lus qhia, thiab lwm yam rau cov neeg siv khoom;

● MCM tau muab ntau tshaj 4000 roj teeb CE kuaj thoob ntiaj teb txog niaj hnub no.

Raws li kev txheeb cais yav dhau los, 80% ntawm spontaneous combustion xwm txheej ntawm lub zog tshiab tsheb tshwm sim
thaum them nyiaj lossis ib teev tom qab them tag nrho. Ntawm ntau qhov laj thawj rau qhov hluav taws kub thiab tawg ntawm lithium roj teeb, overcharging yog ib qho tseem ceeb tshaj plaws.
Lub lithium hlau phosphate roj teeb tau lees paub los ntawm kev lag luam raws li lub roj teeb uas muaj kev nyab xeeb siab. Nyob rau hauv thiaj li yuav
txheeb xyuas qhov kev nyab xeeb ntawm nws cov overcharge, tus editor xaiv lub roj teeb lithium los ua qhov kev sim overcharge kom pom tias nws muaj tseeb.
Overcharge TestThe Lithium hlau phosphate cell siv nyob rau hauv qhov kev sim yog 3.2V / 100Ah nrog txhuas enclosure. Txhawm rau ua kom muaj zog tshaj lub xeev ntawm lub xov tooj ntawm tes ntau npaum li qhov ua tau, peb twb tau siv 2 zaug ntawm qhov nominal voltage (6.4V) raws li kev them nqi hluav taws xob thiab 2C raws li kev them nyiaj tam sim no. Cov kauj ruam Kev Ntsuas hauv cov txheej txheem
Xaus:
Nws tuaj yeem pom los ntawm cov txiaj ntsig kev xeem uas qhov kev ntsuas kev ntsuas no tau zoo simulates qhov xwm txheej uas tuaj yeem tshwm sim thaum lub xov tooj ntawm tes yog overcharged. Aluminium-plhaub lithium hlau phosphate roj teeb tau dhau lawm
cov txheej txheem xws li o, tso pa, cua sov, thiab kev puas tsuaj yam tsis muaj hluav taws (pom hluav taws) thiab los yog tawg
(tag nrho disintegration) thaum overcharge. Hauv ntau qhov kev sim rov ua dua thiab kev sim dhau los, nws tau xaus lus tias
lithium hlau phosphate hlwb muaj kev nyab xeeb nyob rau hauv cov xwm txheej overcharged.
