Nyob rau hauv xyoo tas los no, hluav taws xob tsheb hluav taws xob tau tshwm sim ib qho zuj zus, tshwj xeeb tshaj yog nyob rau lub caij ntuj sov kub, cov tsheb hluav taws xob tau yooj yim rau qhov hluav taws kub thiab ua rau hluav taws kub!
Raws li 2021 lub teb chaws tua hluav taws pab cawm lub tswb ceeb toom thiab cov ntaub ntawv hluav taws tso tawm los ntawm Lub Tsev Haujlwm Saib Xyuas Hluav Taws Xob ntawm Ministry of Emergency Management, ze li ntawm 18000 qhov hluav taws kub thiab 57 tus neeg tuag los ntawm kev tsis ua haujlwm ntawm lub tsheb kauj vab hluav taws xob thiab lawv cov roj teeb tau tshaj tawm thoob tebchaws xyoo tas los.Nws tau tshaj tawm tias 26 lub tsheb kauj vab hluav taws xob tau tshwm sim hauv Yantai hauv ib nrab xyoo no.
Dab tsi ua rau hluav taws xob tsheb hluav taws xob tshwm sim ntau zaus?
Lub ntsiab culprit tom qab lub spontaneous combustion ntawm hluav taws xob tsheb yog lub thermal runaway ntawm lithium roj teeb.Qhov hu ua thermal runaway yog cov tshuaj tiv thaiv kab mob tshwm sim los ntawm ntau yam kev txhawb siab.Tus nqi calorific tuaj yeem nce lub roj teeb kub los ntawm ntau txhiab degrees, ua rau muaj kev sib tsoo tshwm sim.Cov roj teeb tsheb hluav taws xob muaj qhov cuam tshuam rau thermal runaway vim overcharge, puncture, kub kub, luv luv Circuit Court, sab nraud quab yuam puas thiab lwm yam.
Yuav ua li cas kom zoo tiv thaiv thermal runaway
Lub induces ntawm tshav kub tawm ntawm kev tswj yog ntau haiv neeg.Yog li ntawd, ntau yam kev tiv thaiv yuav tsum tau coj los tiv thaiv qhov tshwm sim ntawm cov cua sov tawm ntawm kev tswj.
Lub ntsiab inducement ntawm thermal runaway yog "kub".Txhawm rau tiv thaiv kom tsis txhob muaj cua sov, nws yog qhov tsim nyog los xyuas kom meej tias lub roj teeb tau ua haujlwm ntawm qhov kub thiab txias.Txawm li cas los xij, nyob rau lub caij ntuj sov kub, "tshav kub" yog qhov tsis tuaj yeem zam, yog li peb yuav tsum pib nrog lub roj teeb, thiaj li ua kom lub roj teeb lithium-ion muaj cov cua sov zoo dua thiab kev ua haujlwm kub dissipation.
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 lub tsheb hluav taws xob, thiab seb cov khoom siv hauv cov roj teeb puas muaj qhov kub thiab txias thiab kev ua haujlwm kub.Qhov thib ob, txawm hais tias lub connector txuas nrog lub roj teeb hauv lub tsheb hluav taws xob muaj qhov kub thiab txias ua haujlwm, peb yuav tsum xyuas kom meej tias lub connector yuav tsis soften thiab poob vim qhov kub thiab txias, thiaj li yuav xyuas kom meej tias lub Circuit Court yog unblocked thiab zam qhov tshwm sim ntawm luv luv. Circuit Court.
Raws li tus kws tshaj lij hluav taws xob tsheb txuas tus kws tshaj lij, Amassmuaj 20 xyoo ntawm kev tshawb fawb thiab kev loj hlob kev paub nyob rau hauv lithium electric tsheb connectors, thiab muab tam sim no nqa kev sib txuas kev daws teeb meem rau hluav taws xob tsheb tuam txhab uas muag xws li Xinri, Emma, Yadi, thiab lwm yam. Lub connector ntawm Ames kub resistant hluav taws xob tsheb adopts PBT nrog zoo kub kuj, huab cua kuj thiab hluav taws xob yam ntxwv.Lub melting point ntawm PBT insulating yas plhaub yog 225-235℃.

Cov kev sib txuas ntawm cov tsheb hluav taws xob kub kub tau dhau qhov kev ntsuas nplaim hluav taws kub, thiab cov nplaim hluav taws kub hnyiab tau ncav cuag V0 nplaim hluav taws kub, uas tuaj yeem ua tau raws li qhov ntsuas kub ntawm -20 ℃ ~ 120 ℃.Rau kev siv nyob rau hauv qhov saum toj no ambient kub ntau yam, lub plhaub tseem ceeb ntawm lub tsheb hluav taws xob connector yuav tsis soften vim kub kub, ua rau ib tug luv luv Circuit Court.
Ntxiv rau kev xaiv cov roj teeb thiab lawv cov khoom, qhov zoo ntawm lub tsheb fais fab chargers, lub sijhawm them ntev, kev hloov pauv tsis raug cai ntawm lub tsheb fais fab, thiab lwm yam yog tus yuam sij los txhim kho kev nyab xeeb ntawm lub tsheb fais fab lithium roj teeb.
