UL 1973:2022 uhlengahlengiso olukhulu2

Isishwankathelo

UL 1973:2022 yapapashwa nge-25 kaFebruwari. Olu guqulelo lusekwe kwidrafti yeengcebiso ezimbini ezikhutshwe ngoMeyi nango-Okthobha ka-2021. Umgangatho olungisiweyo wandisa uluhlu lwayo, kubandakanywa inkqubo yamandla yomncedisi wesithuthi (umzekelo, ukukhanya kunye nonxibelelwano).

Ukutshintsha kogxininiso

1.Fakela 7.7 Isiguquli: isiguquli senkqubo yebhetri siya kuqinisekiswa phantsi kwe-UL 1562 kunye ne-UL 1310 okanye imigangatho efanelekileyo. Amandla ombane aphantsi anokuqinisekiswa phantsi kwe-26.6.

2.Uhlaziyo lwe-7.9: IiSekethe eziKhuselekileyo kunye noLawulo: inkqubo yebhetri iya kubonelela ngokutshintsha okanye i-breaker, ubuncinane obufunekayo ukuba ibe yi-60V endaweni ye-50V. Imfuneko eyongezelelweyo yomyalelo we-overcurrent fuse

3.Uhlaziyo lwe-7.12 Iiseli (iibhetri kunye ne-electrochemical capacitor): Kwiiseli ze-Li-ion ezinokutshajwa kwakhona, uvavanyo phantsi kwesihlomelo E lufunekayo, ngaphandle kokuqwalasela i-UL 1642. i-insulator, ukugubungela i-anode kunye ne-cathode, njl.

4.Fakela iRhafu yeRhafu ePhakamileyo ye-16: Vavanya ukhuseleko lokutshaja lwesixokelelwano sebhetri enobuninzi bokutshaja bangoku. Kufuneka kuvavanywe nge-120% yezinga eliphezulu lokutshaja.

5.Fakela uvavanyo lweSekethe olufutshane lwe-17: Yenza uvavanyo olufutshane lwesekethe kwiimodyuli zebhetri ezifuna ukufakela ifayile okanye utshintsho.

6.Fakela i-18 i-Overload Ngaphantsi koKukhupha: Vavanya amandla enkqubo yebhetri ngomthwalo ogqithisiweyo phantsi kokukhutshwa. Kukho iimeko ezimbini zovavanyo: okokuqala kumthwalo ogqithisiweyo phantsi kokukhutshwa apho ikhoyo iphezulu kunomlinganiselo ophezulu wokukhupha okwangoku kodwa ungaphantsi kwe-BMS yokukhusela ngokugqithisileyo; okwesibini kuphezulu kune-BMS ngaphezu kokukhuselwa kwangoku kodwa ngaphantsi kwinqanaba le-1 lokukhusela okwangoku.

7.Fakela uvavanyo lwe-Electromagnetic Immunity engama-27: zizonke iimvavanyo ezisi-7 ngolu hlobo lulandelayo:

  • Ukukhutshwa kombane (i-IEC 61000-4-2)
  • I-radio-frequency electromagnetic field (ireferensi ye-IEC 61000-4-3)
  • Ukhuseleko olukhawulezayo oludlulayo / olugqabhukileyo (ireferensi ye-IEC 61000-4-4)
  • Ukhuseleko lweSurge (ireferensi ye-IEC 61000-4-5)
  • Imo yerediyo-frequency eqhelekileyo (ireferensi IEC 61000-4-6)
  • Intsimi yemagnethi yokuphindaphinda amandla (i-IEC 61000-4-8)
  • Ukuqinisekiswa kokusebenza

8.Fakela isihlomelo esi-3: isihlomelo G (esinolwazi) Uguqulo lokumakisha ngokhuseleko; isihlomelo H (esiqhelekileyo) Enye indlela yokuvavanya ivalvu elawulwayo okanye i-asidi yelothe ekhupha umoya okanye iibhetri zenickel cadmium; isihlomelo I (esiqhelekileyo) : inkqubo yovavanyo lweebhetri zomoya zentsimbi ezitshajwa ngoomatshini.

Isilumkiso

Isatifikethi se-UL 1642 seeseli asisayi kuphinda samkelwe kwiibhetri phantsi kwesiqinisekiso se-UL1973.
