Puas yog lithium hlau phosphate cell muaj kev nyab xeeb nyob rau hauv cov xwm txheej overcharge?,
Lithium,

▍ 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 kev txheeb cais yav dhau los, 80% ntawm spontaneous combustion xwm txheej ntawm lub zog tshiab tsheb tshwm sim
thaum them nyiaj lossis ib teev tom qab them tag nrho. Ntawm ntau qhov laj thawj rau qhov hluav taws kub thiab tawg ntawm lithium roj teeb, overcharging yog ib qho tseem ceeb tshaj plaws.
Lub lithium hlau phosphate roj teeb tau lees paub los ntawm kev lag luam raws li lub roj teeb uas muaj kev nyab xeeb siab. Nyob rau hauv thiaj li yuav
txheeb xyuas qhov kev nyab xeeb ntawm nws cov overcharge, tus editor xaiv lub roj teeb lithium los ua qhov kev ntsuam xyuas overcharge kom pom tias nws muaj tseeb.
Overcharge Test CovLithiumhlau phosphate cell siv nyob rau hauv kev sim yog 3.2V / 100Ah nrog txhuas enclosure. Txhawm rau kom muaj zog tshaj lub xeev ntawm lub xov tooj ntawm tes ntau npaum li qhov ua tau, peb twb tau siv 2 zaug ntawm nominal voltage (6.4V) raws li kev them nqi hluav taws xob thiab 2C raws li them tam sim no.
1. Txuas lub roj teeb ntawm tes mus rau lub zog DC tswj lossis cov khoom siv them thiab tawm;
2. Muab cov thermocouple xaim nyob rau hauv nruab nrab ntawm lub xov tooj ntawm tes thiab ze rau qhov zoo thiab qhov tsis zoo terminals rau
saib xyuas qhov kub thiab txias ntawm tes ntawm lub sijhawm.
