Thaum Lub Tsib Hlis 21, 2021, UL official lub vev xaib tau tshaj tawm cov ntsiab lus tawm tswv yim tshiab ntawm UL1973 roj teeb tus qauv rau chaw nres tsheb, tsheb thauj khoom siv hluav taws xob thiab lub teeb rail (LER) daim ntawv thov. Hnub kawg rau kev tawm tswv yim yog Lub Xya Hli 5, 2021. Cov hauv qab no yog 35 lub tswv yim:

1. Kev sim ntawm Modules thaum lub sij hawm luv luv Circuit Court test.

2. Kev kho kho.

3. Ntxiv qhov kev zam rau General Performance Section rau lub sij hawm xeem rau lithium ion hlwb

los yog roj teeb.

4. Kev hloov kho rau Table 12.1, Lus Cim (d) rau kev poob ntawm kev tswj hwm thawj zaug.

5. Ntxiv qhov Kev Zam Txim Rau Qhov Kev Ntsuam Xyuas Kev Nyuaj Siab SOC.

6. Ntxiv qhov kev zam rau kev siv sab nraum zoov nkaus xwb nyob rau hauv ib qho Cell Failure Design Tolerance test.

7. Tsiv tag nrho lithium cell yuav tsum tau mus rau UL 1973.

8. Ntxiv cov kev cai rau repurposing roj teeb.

9. Kev qhia meej ntawm cov kua qaub roj teeb uas yuav tsum tau ua.

10. Ntxiv rau Lub Tsheb Pab Txhawb Lub Hwj Chim Kev Xav Tau.

11. Kev hloov kho rau Kev Xeem Hluav Taws Xob Sab Nraud.

12. Ntxiv txoj kev kuaj cell los ntawm UL 9540A rau kev sau cov ntaub ntawv.

13. Kev qhia meej rau cov txheej txheem sib nrug thiab kev ua qias tuaj hauv 7.5.

14. Ntxiv kev ntsuas ntawm cov cell voltages thaum lub sij hawm overcharge thiab overdischarge xeem.

15. Kev nthuav qhia ntawm ib leeg ntawm tes tsis ua haujlwm tsim kev sim siab.

16. Cov lus pom zoo rau cov roj teeb electrolyte ntws.

17. Kev suav nrog mechanically recharged hlau cua roj teeb yuav tsum.

18. Kev hloov kho kev nyab xeeb ua haujlwm.

19. Kev ntsuas EMC rau kev tswj xyuas kev nyab xeeb hauv hluav taws xob.

20. Kev nthuav qhia ntawm Dielectric Voltage Withstand Test qhov chaw ntawm cov qauv.

21. SELV txwv rau Canada.

22. Kev hloov kho rau Tshooj 7.1 los hais txog txhua yam khoom tsis yog hlau.

23. Daim ntawv thov daim phiaj ntse.

24. Cov Lus Qhia rau Cov Lus Qhia Ntxiv C.

25. Ntxiv cov qauv kev ua raws li P – Tsis muaj kev tiv thaiv kev tiv thaiv rau Kev Ntsuas Kev Ntsuas.

26. Kev suav nrog sodium ion technology roj teeb.

27. Kev nthuav dav ntawm phab ntsa fixture test kom muaj lwm yam kev txhawb nqa.

28. Kev soj ntsuam daim ntawv thov rau kev txiav txim siab galvanic corrosion.

29. Kev hloov kho ntawm qhov yuav tsum tau ua hauv av hauv 7.6.3.

30. aR Fuse Consideration thiab Module/component voltage consideration.

31. Ntxiv cov txheej txheem rau transformers.

32. Tshaj tawm hauv qab tso tawm.

33. Ntxiv qhov Kev Ntsuas Tus Nqi Siab.

34. Kev hloov ntawm UL 60950-1 nrog UL 62368-1.

35. Kev hloov kho cov qauv kev tiv thaiv hauv Cov Ntawv Ntxiv A.

Cov ntsiab lus ntawm qhov kev pom zoo no suav nrog ntau qhov dav, feem ntau los nthuav dav kev siv ntawm UL1973. Cov ntsiab lus tag nrho ntawm lub tswv yim tuaj yeem tau txais los ntawm qhov txuas hauv qab no.

Yog xav paub ntxiv txog cov lus qhia ntxaws ntxaws, koj tuaj yeem tiv tauj thiab tawm tswv yim rau peb, thiab peb yuav muab cov kev xav sib koom ua ke rau STP Battery Standards Committee.
