Mwachidule

UL 1973:2022 idasindikizidwa pa 25 February. Mtunduwu umachokera pamalingaliro awiri omwe adaperekedwa mu Meyi ndi Okutobala 2021. Mulingo wosinthidwa umakulitsa kuchuluka kwake, kuphatikiza makina othandizira mphamvu zamagalimoto (mwachitsanzo, kuwunikira ndi kulumikizana).

Kusintha kwa kutsindika

1.Append 7.7 Transformer: thiransifoma ya kachitidwe ka batri iyenera kutsimikiziridwa pansi pa UL 1562 ndi UL 1310 kapena miyezo yoyenera. Mphamvu yotsika imatha kutsimikiziridwa pansi pa 26.6.

2.Kusintha 7.9: Mayendedwe Oteteza ndi Kuwongolera: dongosolo la batri lidzapereka chosinthira kapena chophwanyira, chomwe chiyenera kukhala 60V m'malo mwa 50V. Zofunikira zowonjezera pakuwongolera kwa fuse ya overcurrent

3.Kusintha Maselo a 7.12 (mabatire ndi electrochemical capacitor): Kwa maselo a Li-ion omwe amatha kuwonjezeredwa, kuyesa pansi pa annex E kumafunika, popanda kuganizira za UL 1642. Maselo amafunikanso kufufuzidwa ngati akukwaniritsa zofunikira za mapangidwe otetezeka, monga zinthu ndi malo a insulator, kuphimba anode ndi cathode, etc.

4.Append 16 High Rate Charge: Yang'anani chitetezo cholipiritsa cha makina a batri omwe ali ndi mphamvu yowonjezereka. Muyenera kuyesa mu 120% ya kuchuluka kwa ndalama zolipiritsa.

5.Append 17 Short Circuit Test: Chitani mayeso afupipafupi afupipafupi a ma modules a batri omwe amafunika kuyika mafayilo kapena kusintha.

6.Append 18 Yodzaza Pansi pa Kutaya: Unikani mphamvu ya dongosolo la batri ndi katundu wambiri pansi pa kutayidwa. Pali zikhalidwe ziwiri zoyezetsa: choyamba ndi chodzaza kwambiri pansi pa kutayidwa kumene panopa ndipamwamba kuposa momwe amachitira pakalipano koma otsika kuposa panopa a chitetezo cha BMS overcurrent; yachiwiri ndi yapamwamba kuposa BMS pachitetezo chapano koma chotsika kuposa 1 chitetezo chapano.

7.Append 27 Electromagnetic Immunity Test: mayeso 7 kwathunthu motere:

• Electrostatic discharge (IEC 61000-4-2)
• TS EN 61000-4-3 ma radio frequency electromagnetic field (IEC 61000-4-3)
• Kutetezedwa kwachangu kwakanthawi / kuphulika (mawu a IEC 61000-4-4)
• Kuteteza chitetezo chokwanira (IEC 61000-4-5)
• Mawayilesi pafupipafupi (mawu a IEC 61000-4-6)
• Mphamvu yamagetsi yamagetsi yamagetsi (IEC 61000-4-8)
• Kutsimikizira ntchito

8.Onjezani zowonjezera 3: annex G (zodziwitsa) Kumasulira kwa chizindikiro chachitetezo; annex H (normative) Njira ina yowunikira ma valve oyendetsedwa ndi asidi kapena mabatire a nickel cadmium; annex I (normative) : pulogalamu yoyesera ya mabatire achitsulo opangidwanso mwamakina.

Chenjezo

Satifiketi ya UL 1642 yama cell sidzazindikirikanso pamabatire pansi pa satifiketi ya UL1973.
