▍ Daim ntawv pov thawj TISI yog dab tsi?

TISI yog luv luv rau Thai Industrial Standards Institute, koom nrog Thailand Industry Department. TISI yog lub luag haujlwm rau kev tsim cov qauv hauv tsev nrog rau kev koom tes hauv kev tsim qauv thoob ntiaj teb thiab saib xyuas cov khoom thiab cov txheej txheem kev soj ntsuam tsim nyog los xyuas kom meej cov qauv ua raws thiab kev lees paub. TISI yog ib lub koom haum uas tau tso cai los ntawm tsoom fwv rau kev cai lij choj pov thawj hauv Thaib teb. Nws tseem yog lub luag haujlwm rau kev tsim thiab tswj cov qauv, kev pom zoo hauv lab, kev cob qhia cov neeg ua haujlwm thiab kev sau npe ntawm cov khoom. Nws raug sau tseg tias tsis muaj lub koom haum tsis yog tsoomfwv cov ntawv pov thawj hauv Thaib teb.

Muaj daim ntawv pov thawj txaus siab thiab yuav tsum tau ua hauv Thaib teb. TISI logos (saib daim duab 1 thiab 2) raug tso cai siv thaum cov khoom ua tau raws li cov qauv. Rau cov khoom lag luam uas tseem tsis tau muaj tus qauv, TISI kuj tseem siv cov khoom sau npe ua cov ntawv pov thawj ib ntus.

▍ Yuav Tsum Tau Certification Scope

Cov ntawv pov thawj yuav tsum tau them 107 pawg, 10 thaj chaw, suav nrog: cov khoom siv hluav taws xob, khoom siv, khoom siv kho mob, cov khoom siv, cov khoom siv, tsheb, PVC kav, LPG gas ntim thiab cov khoom ua liaj ua teb. Cov khoom lag luam dhau qhov peev txheej no yog poob rau hauv daim ntawv pov thawj yeem. Roj teeb yog cov khoom siv ntawv pov thawj hauv TISI daim ntawv pov thawj.

Applied standard:TIS 2217-2548 (2005)

Cov roj teeb siv:Cov xov tooj thib ob thiab cov roj teeb (muaj cov alkaline lossis lwm yam tsis yog-acid electrolytes - kev nyab xeeb rau cov khoom siv sib txuas, thiab cov roj teeb uas tsim los ntawm lawv, siv rau hauv daim ntawv thov portable)

Txoj cai muab daim ntawv tso cai:Thai Industrial Standards Institute

▍ Vim li cas MCM?

● MCM koom tes nrog cov koom haum tshawb xyuas lub Hoobkas, chav kuaj thiab TISI ncaj qha, muaj peev xwm muab cov ntawv pov thawj zoo tshaj plaws rau cov neeg siv khoom.

● MCM muaj 10 xyoo kev paub ntau hauv kev lag luam roj teeb, muaj peev xwm muab kev txhawb nqa kev tshaj lij.

● MCM muab kev pabcuam ib-nres los pab cov neeg siv khoom nkag mus rau hauv ntau lub khw (tsis yog Thaib teb suav nrog) ua tiav nrog cov txheej txheem yooj yim.

Raws li cov ntaub ntawv tsis ntev los no tau tshaj tawm los ntawm Tuam Tshoj Ministry of Emergency Management, 640 qhov xwm txheej hluav taws kub ntawm lub zog tshiab tau tshaj tawm nyob rau thawj peb lub hlis twg xyoo 2022, nce 32% nyob rau tib lub sijhawm xyoo tas los, nrog qhov nruab nrab ntawm 7 hluav taws kub ib hnub. Tus sau tau ua qhov kev txheeb xyuas los ntawm lub xeev ntawm qee qhov hluav taws kub EV, thiab pom tias tus nqi hluav taws xob hauv lub xeev tsis siv, lub xeev tsav tsheb thiab lub xeev them nqi ntawm EV tsis txawv ntawm ib leeg, raws li qhia hauv daim duab hauv qab no. Tus kws sau ntawv yuav ua ib qho kev ntsuam xyuas yooj yim ntawm qhov ua rau hluav taws kub hauv peb lub xeev no thiab muab cov tswv yim tsim kev nyab xeeb.
Txawm hais tias qhov xwm txheej twg ua rau lub roj teeb hluav taws kub lossis tawg, lub hauv paus ua rau yog qhov luv luv hauv lossis sab nraud ntawm tes, uas ua rau thermal khiav ntawm lub cell. Tom qab lub thermal runaway ntawm ib lub xov tooj ntawm tes, nws thaum kawg yuav ua rau tag nrho cov pob ntes hluav taws yog tias thermal nthuav tawm tsis tuaj yeem zam vim yog cov qauv tsim ntawm module lossis pob. Ua rau sab hauv lossis sab nraud luv luv ntawm lub xov tooj ntawm tes yog (tab sis tsis txwv rau): overheating, overcharge, tshaj tawm, mechanical force (crush, shock), circuit aging, metal particles into the cell in production process, etc.
Thaum lub xov tooj ntawm tes tau txais cov cua sov sab nraud los yog nws tus kheej tsim cov cua sov thiab tsis tuaj yeem tawg rau lub sijhawm, thiab qhov kub ntawm lub xov tooj ntawm tes tshaj qhov kub ntawm cov khoom siv sab hauv (separator), tus separator yuav cog lus, uas ua rau luv luv Circuit Court ntawm qhov zoo thiab tsis zoo electrodes. .
