Uhlolojikelele

UL 1973:2022 yashicilelwa ngomhla zingama-25 kuNhlolanja. Le nguqulo isuselwe kokusalungiswa kweziphakamiso ezimbili ezikhishwe ngoMeyi nango-Okthoba ka-2021. Izinga elishintshiwe landisa ububanzi balo, okuhlanganisa umsizi wesistimu yamandla wemoto (isb. ukukhanya nokuxhumana).

Ukushintsha kokugcizelela

1.Yengeza okuthi 7.7 I-Transformer: i-transformer yohlelo lwebhethri izogunyazwa ngaphansi kwe-UL 1562 ne-UL 1310 noma amazinga afanelekile. I-voltage ephansi ingagunyazwa ngaphansi kwe-26.6.

2.Buyekeza 7.9: Izifunda Zokuvikela Nokulawula: isistimu yebhethri izohlinzeka ngeswishi noma i-breaker, ubuncane bayo obudingekayo ukuze kube ngu-60V esikhundleni sika-50V. Isidingo esingeziwe somyalelo we-overcurrent fuse

3.Buyekeza 7.12 Amaseli (amabhethri kanye ne-electrochemical capacitor): Kumaseli e-Li-ion aphinde ashajwa, ukuhlolwa ngaphansi kwe-annex E kuyadingeka, ngaphandle kokucabangela i-UL 1642. Amaseli ayadingeka futhi ukuba ahlaziywe uma ehlangabezana nesidingo sedizayini ephephile, njengempahla nendawo i-insulator, ukumbozwa kwe-anode ne-cathode, njll.

4.Yengeza 16 Imali Yezinga Eliphezulu: Hlola ukuvikelwa kokushaja kwesistimu yebhethri ngokushaja okuphezulu kwamandla wamanje. Kudingeka ukuhlola ngo-120% wesilinganiso sokushaja esiphezulu.

5.Yengeza Ukuhlolwa Kwesekethe Efushane engu-17: Yenza ukuhlolwa kwesekethe emfushane yamamojula ebhethri adinga ukufakwa kwefayela noma ukushintshwa.

6.Yengeza 18 Ukugcwala Okugcwele Ngaphansi Kokukhipha: Hlola ikhono lesistimu yebhethri ngokugcwala ngokweqile ngaphansi kokukhipha. Kunezimo ezimbili zokuhlolwa: eyokuqala igcwele ngokweqile ngaphansi kokukhipha lapho igagasi liphakeme kunesilinganiso esiphezulu samanje sokukhipha amanzi kodwa siphansi kunokwamanje sokuvikela okudlulele kwe-BMS; eyesibili iphakeme kune-BMS ngaphezu kokuvikela kwamanje kodwa iphansi kuneleveli 1 yamanje yokuvikela.

7.Append 27 Electromagnetic Immunity Test: 7 ngokuphelele izivivinyo ngendlela elandelayo:

• Ukukhishwa kwe-Electrostatic (inkomba ye-IEC 61000-4-2)
• Inkambu ye-radio-frequency electromagnetic (inkomba ye-IEC 61000-4-3)
• Ukungavikeleki kwesikhashana okusheshayo/ukuqhuma (inkomba ye-IEC 61000-4-4)
• I-Surge immunity (inkomba ye-IEC 61000-4-5)
• Imodi evamile yerediyo-frequency (inkomba IEC 61000-4-6)
• Inkambu kazibuthe yefrikhwensi yamandla (inkomba ye-IEC 61000-4-8)
• Ukuqinisekiswa kokusebenza

8.Yengeza isijobelelo esingu-3: isijobelelo G (esinolwazi) Ukuhumusha kokuphepha kokumaka; isijobelelo H (esivamile) Enye indlela yokuhlola i-valve elawulwayo noma i-vent lead acid noma amabhethri e-nickel cadmium; annex I (normative) : uhlelo lokuhlola lwamabhethri omoya ensimbi aphinde ashajwe ngomshini.

Isexwayiso

Isitifiketi se-UL 1642 samaseli ngeke sisaqashelwa ngamabhethri ngaphansi kwesitifiketi se-UL1973.
