Txheej txheem cej luam

UL 1973: 2022 tau luam tawm thaum Lub Ob Hlis 25th.Cov qauv no yog raws li ob lub tswv yim tawm tswv yim tawm thaum lub Tsib Hlis thiab Lub Kaum Hli 2021. Cov qauv hloov kho nthuav dav, suav nrog lub zog pab lub zog (xws li teeb pom kev zoo thiab kev sib txuas lus).

Hloov ntawm qhov tseem ceeb

1.Append 7.7 Transformer: transformer rau roj teeb system yuav tsum tau ntawv pov thawj raws li UL 1562 thiab UL 1310 los yog cov qauv tsim nyog.Tsawg voltage tuaj yeem lees paub hauv qab 26.6.

2.Hloov tshiab 7.9: Kev tiv thaiv Circuit Court thiab Tswjhwm: roj teeb lub cev yuav tsum muab hloov lossis tawg, qhov tsawg kawg nkaus yuav tsum yog 60V hloov 50V.Ntxiv kev xav tau rau kev qhia rau overcurrent fuse

3.Update 7.12 Cells (roj teeb thiab electrochemical capacitor): Rau cov roj ntsha Li-ion rechargeable, yuav tsum tau kuaj nyob rau hauv annex E, yam tsis xav txog UL 1642. Cells yuav tsum tau soj ntsuam yog tias ua tau raws li qhov xav tau ntawm kev nyab xeeb tsim, xws li cov khoom thiab txoj hauj lwm ntawm insulator, kev them nyiaj ntawm anode thiab cathode, thiab lwm yam.

4.Append 16 High Rate Charge: Ntsuam xyuas kev tiv thaiv kev tiv thaiv roj teeb nrog ntau tshaj qhov them tam sim no.Yuav tsum tau kuaj hauv 120% ntawm qhov siab tshaj plaws them tus nqi.

5.Append 17 Short Circuit Test: Ua luv luv Circuit Court kuaj rau cov roj teeb modules uas xav tau kev teeb tsa lossis hloov.

6.Append 18 Overload Under Discharge: Ntsuas lub peev xwm ntawm cov roj teeb uas muaj peev xwm tshaj tawm hauv qab.Muaj ob txoj hauv kev rau kev sim: thawj zaug yog nyob rau hauv overload nyob rau hauv kev tso tawm nyob rau hauv uas tam sim no siab tshaj qhov ntsuas qhov siab tshaj tawm tam sim no tab sis qis dua tam sim no ntawm BMS overcurrent tiv thaiv;qhov thib ob yog siab tshaj BMS tshaj kev tiv thaiv tam sim no tab sis qis dua qib 1 tiv thaiv tam sim no.

7.Append 27 Electromagnetic Immunity Test: tag nrho 7 xeem raws li nram no:

• Electrostatic paug (IEC 61000-4-2)
• Xov tooj cua zaus electromagnetic teb (IEC 61000-4-3)
• Kev tiv thaiv kab mob nrawm nrawm nrawm nrawm (IEC 61000-4-4)
• Kev tiv thaiv kev tiv thaiv kab mob (IEC 61000-4-5)
• Xov tooj cua zaus hom (IEC 61000-4-6)
• IEC 61000-4-8 Lub zog-zaus magnetic teb
• Kev ua haujlwm pov thawj

8.Append 3 annex: annex G (cov ntaub ntawv) Kev nyab xeeb cim txhais lus;annex H (normative) Lwm txoj hauv kev rau kev ntsuas lub valve tswj lossis vented lead acid lossis nickel cadmium roj teeb;annex I (normative): test program for mechanically rechargeable metal-air batteries.

Ceev faj

UL 1642 daim ntawv pov thawj rau cov hlwb yuav tsis raug lees paub rau cov roj teeb raws li UL1973 ntawv pov thawj.
