Kev tawg: Peb Cov Khoom Siv Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob tau txais daim ntawv pov thawj UL 2271 - Npaj rau North American Market

1.Cov ntawv pov thawj UL 2271 yog dab tsi?

UL 2271 yog tus qauv kev nyab xeeb tsim los ntawm Underwriters Laboratories (UL), tshwj xeeb tsim rauCov roj teeb siv nyob rau hauv lub teeb hluav taws xob tsheb (LEVs) thiab cov khoom siv txawb.

1) Scope ntawm daim ntawv thov

UL 2271 siv rau lithium{1}} ion roj teeb siv hauv:

Neeg hlau nqus tsev vacuum

Hluav taws xob scooters

Hluav taws xob sib npaug boards / hoverboards

Cov tsheb kauj vab hluav taws xob

Lub rooj zaum fais fab

Lwm yam khoom siv teeb pom kev zoo

2) Cov ntsiab lus tseem ceeb

UL 2271 ntsuas roj teeb kev nyab xeeb hla peb qhov ntev:

Kev nyab xeeb hluav taws xob: Tsis muaj hluav taws kub, tsis muaj tawg nyob rau hauv qhov txawv txav xws li overcharge, tshaj - paug, los yog luv luv Circuit Court

Mechanical kev nyab xeeb: Tsis muaj dej xau, tsis muaj hluav taws kub, tsis muaj tawg nyob rau hauv lub cev muaj zog xws li tsoo, cuam tshuam, vibration, los yog poob

Ib puag ncig kev nyab xeeb: Kev ua haujlwm ruaj khov nyob rau hauv qhov kub thiab txias, siab - qhov kub thiab txias, thiab qis - lub zog siab

3) Tus nqi lag luam

Hauv North America, UL 2271 yogib qho yuav tsum tau ua rau lithium{0}}ion roj teeb. Yog tsis muaj nws, lub tshuab nqus tsev neeg hlau tsis tuaj yeem muag los ntawm cov khw muag khoom loj lossis tau txais kev ntseeg siab rau cov neeg siv khoom. Daim ntawv pov thawj no yog lub rooj vag mus rau North American lag luam.

2.UL 2271 Cov Khoom Xeem - Txhua yam dhau los nrog kev ua tau zoo

Cov txheej txheem ntawv pov thawj UL 2271 suav nrog cov kev xeem nruj. Peb cov roj teeb tau dhau txhua qhov kev xeem yam tsis muaj kev zam. Hauv qab no yog cov ntsiab lus ntawm cov kev xeem tseem ceeb thiab peb cov txiaj ntsig.

3.Qhov ntawv pov thawj UL 2271 txhais li cas rau peb cov neeg siv khoom?

UL 2271 yog ntau tshaj li daim ntawv pov thawj - nws muab tus nqi tiag tiag rau peb cov neeg siv khoom.

Tsis xav tau kev sim dua: Siv peb cov roj teeb uas muaj ntawv pov thawj thiab koj cov khoom tag nrho ua tau raws li North American kev ruaj ntseg

Lub sij hawm sai dua rau kev lag luam: Txuag 3-6 lub hlis ntawm cov ntawv pov thawj coj mus kuaj

Tsawg tus nqi ua raws cai: Zam tsis pub tshaj kaum txhiab daus las hauv cov nqi kuaj

Rau cov neeg siv kawg

Kev kaj siab lug: Daim ntawv pov thawj UL yog ib qho kev ntseeg siab rau cov neeg siv khoom hauv North American

Txhim khu kev ua tau zoo: Cov roj teeb uas dhau qhov kev sim nruj yuav siv sij hawm ntev dua thiab muaj qhov tsis ua haujlwm qis dua

Rau Importers thiab Distributors

Txo kev pheej hmoo ntawm cov saw hlau: Cov roj teeb muaj ntawv pov thawj txo qhov kev pheej hmoo ntawm cov khoom rov qab los ntawm cov teeb meem roj teeb

Lower lav raug: Kev ua raws li UL muab kev tiv thaiv muaj zog hauv cov khoom lag luam lav

Xaiv peb cov roj teeb txhais tau tias xaiv ibkev daws teeb meem thoob ntiaj teb. Txawm hais tias koj lub hom phiaj kev lag luam yog North America, Europe, Nyiv, lossis Tuam Tshoj, peb muaj cov ntawv pov thawj uas koj xav tau.

4.Yuav ua li cas peb ua kom muaj kev sib raug zoo hauv cov khoom muaj ntawv pov thawj

Kev xeem ntawv pov thawj tsuas yog thawj kauj ruam xwb. Kev tswj kom muaj kev sib luag thoob plaws ntau lawm yog qhov tseem ceeb sib npaug. Nov yog qhov peb ua kom txhua lub roj teeb ua tau raws li cov qauv siab:

Cov khoom siv raw tswj: Tag nrho cov khoom tseem ceeb (cells, ICs, MOSFETs, connectors) yog los ntawm sab saum toj -tier hom thiab tau txais 100% kev tshuaj xyuas

Cov txheej txheem tswj: Cov txheej txheem tsim khoom tseem ceeb (vuam, sib dhos, kuaj) raug saib xyuas nrog lub sijhawm tiag tiag -cov chaw kuaj xyuas zoo

100% kev xeem zaum kawg: Txhua lub roj teeb raug kuaj ua ntej xa zaub mov, suav nrog:

Qhib Circuit Court voltage

Sab hauv tsis kam

Charge / tso tawm muaj nuj nqi

Kev sib txuas lus muaj nuj nqi (rau BMS- qauv tsim)

Kev tshuaj xyuas qhov muag

Kev kuaj tsis tu ncua: Peb random qauv roj teeb los ntawm kev tsim khoom txhua lub hlis rau kev rov qab sab hauv -kev sim ntawm cov khoom tseem ceeb UL 2271 kom ntseeg tau tias kev ua raws li txoj cai
