Contents ntawm lub tswv yim:

Thaum Lub Rau Hli 25, 2021, UL official lub vev xaib tau tshaj tawm qhov kev hloov kho tshiab tshaj plaws rau UL2054 tus qauv. Qhov kev thov kev xav yuav kav mus txog rau lub Xya Hli 19, 2021. Cov hauv qab nosyog 6 qhov kev hloov kho hauv qhov kev pom zoo no:

1. Kev suav nrog cov kev cai dav dav rau cov qauv ntawm cov xov hlau thiab cov terminals: lub rwb thaiv tsev ntawm cov xov hlau yuav tsum ua tau raws li cov cai ntawm UL 758;
2. Lwm yam kev hloov kho rau tus qauv: feem ntau yog kev kho tsis raug, hloov tshiab ntawm cov qauv raug suav;
3. Ib qho ntxiv ntawm kev xeem yuav tsum tau ua rau cov nplaumness: so kuaj nrog dej thiab cov kuab tshuaj organic;
4. Kev nce qib ntawm kev tswj hwm ntawm cov khoom siv thiab cov khoom siv hluav taws xob nrog tib txoj kev tiv thaiv hauv kev ntsuas hluav taws xob: Yog tias obzoo ib yamcov khoomor circuits ua haujlwmua kelos tiv thaiv lub roj teeb, thaum txiav txim siab ib qho txhaum, ob qho tib si los yog circuits yuav tsum tau ua txhaum tib lub sijhawm.
5. Kos qhov kev sim ntsuas hluav taws xob tsawgasxaiv tau: seb qhov txwv tsis pub siv hluav taws xob sim hauv Tshooj 13 ntawm tus qauv yog ua tiav yuav raug txiav txim raws li cov neeg tsim khoom xav tau.
6. Kev hloov kho ntawm 9.11 clause-Kev ntsuas hluav taws xob sab nraud: tus qauv qub yog siv 16AWG (1.3mm2) liab qab tooj liab hlau; kev hloov kho tswv yim:tnws sab nraud kuj ntawm luv luv Circuit Courtyuav tsum yog80 ± 20mΩ liab qab tooj liab hlau.

Influence ntawm lub tswv yim ntawm lub roj teeb tsim:

Tshooj 4 ntawm lubtswv yimTej zaum yuav muaj feem cuam tshuam rau lub roj teeb tsim: ib zaug kev hloov kho cov lus pom zoo ntawm qhov ua txhaum ntawm kev tiv thaiv cov khoom siv thiab cov khoom siv hluav taws xob tau txais, thaum kev tiv thaiv yog nqa los ntawm ob lub voj voog lossis cov khoom siv, lwm yam kev tiv thaiv yuav tsum tau ntxiv vimcov qubyuav tsum tau ua txhaum. Piv txwv li, nyob rau hauv lub overcharge test, yog tias obib yamMOSFETs siv rau kev tiv thaiv overcharge yuav tsum tau ua txhaum yam tsis muaj lwm yam kev tiv thaiv overchargeua haujlwm, lub roj teeb poob lub overcharge tiv thaiv thiab qhov kev ntsuam xyuas yog tsis yooj yim sua.

Hauv cov ntsiab lus, nws raug pom zoo tias cov tuam txhab tsim khoom siv ob txoj kev tiv thaiv sib txawv thaum tsim lub roj teeb los daws cov kev hloov pauv tom ntej.
