5 tus qauv tso cai tshaj plaws rau kev nyab xeeb roj teeb (cov qauv hauv ntiaj teb)

Lithium-ion roj teebsystems yog complex electrochemical thiab mechanical systems, thiab kev nyab xeeb ntawm lub roj teeb pob yog ib qho tseem ceeb nyob rau hauv hluav taws xob tsheb.Tuam Tshoj "Cov Lus Qhia Txog Kev Nyab Xeeb Kev Nyab Xeeb Hluav Taws Xob", uas tau hais meej meej tias lub roj teeb yuav tsum tsis txhob ntes hluav taws lossis tawg tsis pub dhau 5 feeb tom qab thermal runaway ntawm lub roj teeb monomer, tawm hauv lub sijhawm khiav nyab xeeb rau cov neeg nyob.

(1) Thermal kev nyab xeeb ntawm lub hwj chim roj teeb

Qhov kub qis tuaj yeem ua rau lub roj teeb tsis zoo thiab ua rau muaj kev puas tsuaj, tab sis feem ntau tsis ua rau muaj kev phom sij.Txawm li cas los xij, overcharging (siab dhau heev lawm) tuaj yeem ua rau cathode decomposition thiab electrolyte oxidation.Tshaj tawm (tsis tshua muaj hluav taws xob dhau) tuaj yeem ua rau decomposition ntawm cov khoom electrolyte interface (SEI) ntawm lub anode thiab tej zaum yuav ua rau oxidation ntawm cov ntawv ci tooj liab, ua rau lub roj teeb puas.

(2) IEC 62133 tus qauv

IEC 62133 (Kev ntsuas kev nyab xeeb rau cov roj teeb lithium-ion thiab cov hlwb), yog qhov yuav tsum tau muaj kev nyab xeeb rau kev sim cov roj teeb nruab nrab thiab cov hlwb uas muaj alkaline lossis tsis yog-acidic electrolytes.Nws yog siv los ntsuas cov roj teeb uas siv hauv cov khoom siv hluav taws xob thiab lwm yam kev siv, hais txog tshuaj lom neeg thiab hluav taws xob muaj kev phom sij thiab cov teeb meem siv tshuab xws li kev co thiab kev poob siab uas yuav ua rau cov neeg siv khoom thiab ib puag ncig.

(3)UN/DOT 38.3

UN/DOT 38.3 (T1 - T8 xeem thiab UN ST/SG/AC.10/11/Rev. 5), npog tag nrho cov roj teeb pob, lithium hlau cell thiab roj teeb rau kev kuaj kev nyab xeeb.Tus qauv xeem muaj yim qhov kev xeem (T1 - T8) tsom rau cov kev thauj mus los tshwj xeeb.

(4) IEC 62619 (TSI)

IEC 62619 (Kev Nyab Xeeb Kev Nyab Xeeb rau Secondary Lithium Batteries thiab Roj Teeb Pob), tus qauv qhia txog kev nyab xeeb rau cov roj teeb hauv hluav taws xob thiab lwm yam kev lag luam.Cov kev xeem yuav tsum tau siv rau ob qho tib si nyob ruaj ruaj thiab siv fais fab.Cov ntawv thov nyob ruaj ruaj muaj xws li kev sib txuas lus, cov khoom siv hluav taws xob tsis cuam tshuam (UPS), hluav taws xob txuag hluav taws xob, hloov hluav taws xob, hluav taws xob thaum muaj xwm txheej ceev thiab cov ntawv siv zoo sib xws.Cov ntawv thov muaj zog muaj xws li forklifts, tsheb golf, tsheb tsav tsheb (AGVs), kev tsheb ciav hlau, thiab nkoj (tsis suav nrog tsheb thauj mus los).

(5)wb 2580x

UL 2580x (UL Safety Standard for Electric Vehicle Batteries), muaj ntau yam kev xeem.

High Current Battery Short Circuit: Qhov kev ntsuam xyuas no yog khiav ntawm tus qauv them tag nrho.Cov qauv yog luv luv-circuited siv tag nrho cov hluav taws xob tiv thaiv ntawm ≤ 20 mΩ.Spark ignition kuaj pom qhov muaj cov pa taws ntau ntawm cov pa hauv cov qauv thiab tsis muaj cov cim ntawm kev tawg lossis hluav taws.

Roj teeb Crush: Khiav ntawm tus qauv them tag nrho thiab simulate cov teebmeem ntawm lub tsheb sib tsoo ntawm EESA kev ncaj ncees.Raws li nrog kev ntsuas luv luv Circuit Court, qhov hluav taws xob hluav taws xob kuaj pom qhov muaj cov pa taws ntau ntawm cov pa hauv cov qauv thiab tsis muaj qhov qhia tias muaj kev tawg lossis hluav taws.Tsis muaj cov pa phem tso tawm.

Roj teeb Cell Squeeze (Vertical): Khiav ntawm tus qauv them tag nrho.Lub zog siv nyob rau hauv qhov kev sim nyem yuav tsum raug txwv rau 1000 npaug ntawm qhov hnyav ntawm tes.Spark ignition detection yog tib yam li siv nyob rau hauv qhov kev sim nyem.

(6) Kev Nyab Xeeb Kev Nyab Xeeb rau Tsheb Hluav Taws Xob (GB 18384-2020)

Kev Nyab Xeeb Kev Nyab Xeeb rau Lub Tsheb Hluav Taws Xob" yog ib lub teb chaws tus qauv ntawm Cov Neeg Tuam Txhab Tuam Txhab Tuam Txhab Tuam Tshoj tau siv rau Lub Ib Hlis 1, 2021, uas teev cov kev cai nyab xeeb thiab kev sim rau cov tsheb hluav taws xob.
