Nyob rau hauv xyoo tas los no, Ob lub log hluav taws xob tsheb hluav taws xob tseem tau tshwm sim nyob rau hauv qhov kawg, tshwj xeeb tshaj yog nyob rau lub caij ntuj sov kub, hluav taws xob hluav taws xob yog ib qho yooj yim rau spontaneous combustion!
Raws li 2021 pab neeg tua hluav taws hauv tebchaws tau txais tub ceev xwm thiab cov ntaub ntawv tua hluav taws tso tawm los ntawm Lub Chaw Tiv Thaiv Hluav Taws Xob ntawm Ministry of Emergency Management, ze li ntawm 18,000 qhov hluav taws kub los ntawm ob lub log hluav taws xob thiab lawv cov roj teeb tsis ua haujlwm tau tshaj tawm thoob tebchaws, tua 57 tus neeg. Raws li cov lus ceeb toom, tsuas yog ib nrab xyoo 2022 xyoo no, muaj 26 Ob lub log hluav taws xob tsheb hluav taws kub hauv Yantai.
Dab tsi ua rau Ob lub log hluav taws xob tsheb hluav taws kub ntau heev?
Lub ntsiab culprit tom qab lub spontaneous combustion ntawm Ob wheeled electric tsheb yog lub thermal runaway ntawm lithium roj teeb, lub thiaj li hu ua thermal runaway yog ib tug saw cov tshuaj tiv thaiv tshwm sim los ntawm ntau yam incentives, thiab lub tshav kub tuaj yeem ua rau lub roj teeb kub nce ntau txhiab degrees, ua rau. nyob rau hauv spontaneous combustion. Ob lub log hluav taws xob lub tsheb roj teeb nyob rau hauv overcharge, puncture, kub, luv luv Circuit Court, sab nrauv puas thiab lwm yam yog vim li cas yooj yim ua rau thermal runaway.
Yuav ua li cas tiv thaiv thermal runaway zoo
Lub inducement ntawm thermal runaway yog ntau yam, yog li ntau yam kev tiv thaiv yuav tsum tau ua los tiv thaiv qhov tshwm sim ntawm thermal runaway.
Qhov laj thawj tseem ceeb ntawm thermal runaway yog "kub", kom ntseeg tau tias lub roj teeb tau khiav ntawm qhov kub thiab txias, txhawm rau tiv thaiv qhov tshwm sim ntawm thermal runaway. Txawm li cas los xij, thaum lub caij ntuj sov kub, "tshav kub" yog qhov tsis tuaj yeem zam, tom qab ntawd koj yuav tsum pib ntawm lub roj teeb, kom cov roj teeb lithium-ion muaj cov cua sov zoo dua thiab kev ua haujlwm kub.
Ua ntej tshaj plaws, cov neeg siv khoom yuav tsum tau ua tib zoo saib xyuas cov yam ntxwv ntawm cov roj teeb lithium thaum yuav ob lub log hluav taws xob, thiab seb cov khoom siv sab hauv ntawm lub roj teeb ntawm tes muaj qhov kub thiab txias thiab kev ua haujlwm kub. Qhov thib ob, seb lub connector txuas nrog lub roj teeb hauv lub tsheb hluav taws xob muaj qhov kub thiab txias ua haujlwm, kom ntseeg tau tias lub connector yuav tsis soften thiab poob vim qhov kub siab, thiaj li yuav xyuas kom meej tias lub Circuit Court yog du thiab zam qhov tshwm sim ntawm luv luv Circuit Court. .
Raws li tus kws tshaj lij hluav taws xob tsheb sib txuas cov kws tshaj lij, AmasS muaj 20 xyoo kev paub hauv kev tshawb fawb thiab kev tsim cov lithium hluav taws xob tsheb txuas, thiab muab cov kev daws teeb meem tam sim no rau ob lub log hluav taws xob tsheb tuam txhab xws li SUNRA, AIMA, YADEA. Amass siab kub ob lub log hluav taws xob tsheb txuas tau txais PBT nrog cov cua sov ua haujlwm, huab cua tsis kam thiab cov yam ntxwv hluav taws xob zoo, thiab lub melting point ntawm PBT insulated yas plhaub yog 225-235 ℃.
Cov qauv kev sim muaj zog ua haujlwm thiab cov qauv ntsuas zoo meej yog lub hauv paus rau kev ua kom zoo ntawm ob lub log hluav taws xob tsheb txuas
Amass Laboratory
Kev kub siab ob lub log hluav taws xob tsheb sib txuas tau dhau qhov kev ntsuas nplaim hluav taws kub, nplaim hluav taws kub ua haujlwm mus txog V0 nplaim retardant, kuj tuaj yeem ua tau raws li qhov ntsuas kub ntawm -20 ° C ~ 120 ° C. lub plhaub tseem ceeb ntawm ob lub log hluav taws xob lub tsheb sib txuas yuav tsis muag vim qhov kub thiab txias, ua rau luv luv Circuit Court.
Ntxiv rau qhov kev xaiv ntawm lub roj teeb thiab nws cov khoom, qhov zoo ntawm lub tsheb fais fab charger, lub sijhawm them lub sijhawm ntev dhau lawm, thiab kev hloov pauv tsis raug cai ntawm ob lub log tsheb fais fab yog tus yuam sij rau kev txhim kho kev nyab xeeb ntawm cov hluav taws xob. tsheb lithium roj teeb.
