Nānā nui

Ua paʻi ʻia ka UL 1973：2022 ma ka lā 25 o Pepeluali.Hoʻokumu ʻia kēia mana ma luna o nā manaʻo manaʻo ʻelua i hoʻopuka ʻia ma Mei a me ʻOkakopa o 2021. Hoʻonui ka maʻamau i hoʻololi ʻia i kona laulā, me ka ʻōnaehana kōkua kaʻa (e laʻa i ka mālamalama a me ke kamaʻilio).

Hoʻololi o ka manaʻo nui

1.Append 7.7 Transformer: e hōʻoia ʻia ka mea hoʻololi no ka ʻōnaehana pākahi ma lalo o UL 1562 a me UL 1310 a i ʻole nā ​​kūlana kūpono.Hiki ke hōʻoia ʻia ka uila haʻahaʻa ma lalo o 26.6.

2. Hōʻano hou 7.9: Nā Kaapuni Palekana a me ka Mana: E hāʻawi ka ʻōnaehana pākaukau i ka hoʻololi a i ʻole breaker, ʻo ka liʻiliʻi o ka mea i koi ʻia he 60V ma kahi o 50V.Pono hou no ke aʻo ʻana no ka fuse overcurrent

3.Update 7.12 Cells (pāʻani a me ka electrochemical capacitor): No ka rechargeable Li-ion mau keena, ho'āʻo ma lalo o ka annex E koi 'ia, me ka noonoo ole UL 1642. E pono no hoi na keena ke kālailai ina e halawai me ka makemake o ka palekana manao, e like me ka mea a me ke kūlana o. insulator, ka uhi o ka anode a me ka cathode, etc.

4. Hoʻopili i ka 16 kiʻekiʻe uku uku: E loiloi i ka pale ʻana i ka hoʻopiʻi ʻana o ka ʻōnaehana pākaukau me ka ʻoi aku ka nui o ka hoʻouka ʻana i kēia manawa.Pono e hoʻāʻo ma 120% o ka nui o ka hoʻouka ʻana.

5.Append 17 Short Circuit Test: E hana i ka ho'āʻo kaapuni pōkole no nā modula pākahi e pono ai ke hoʻokomo a hoʻololi paha.

6. Hoʻopili i ka 18 Overload Under Discharge: E loiloi i ka hiki ʻana o ka ʻōnaehana pākaukau me ka overload ma lalo o ka hoʻokuʻu ʻana.ʻElua mau kūlana no ka hoʻāʻo ʻana: ʻo ka mea mua i ka overload ma lalo o ka hoʻokuʻu ʻana i ʻoi aku ka kiʻekiʻe o kēia manawa ma mua o ka helu kiʻekiʻe o ka hoʻokuʻu ʻana i kēia manawa akā ʻoi aku ka haʻahaʻa ma mua o ka pale o ka BMS overcurrent;ʻoi aku ka kiʻekiʻe o ka lua ma mua o BMS ma mua o ka pale o kēia manawa akā ʻoi aku ka haʻahaʻa ma mua o ka pae 1 pale o kēia manawa.

7. Hoʻohui i ka 27 Electromagnetic Immunity Test: ʻo 7 mau hoʻokolohua e like me kēia:

• ʻO ka hoʻokuʻu ʻana i ka electrostatic (ke kuhikuhi IEC 61000-4-2)
• ʻO ke kahua electromagnetic radio-frequency (hōʻike IEC 61000-4-3)
• ʻO ka pale ʻana i ka transient/burst immunity (ke kuhikuhi IEC 61000-4-4)
• Ka pale ʻana i ka piʻi ʻana (e pili ana IEC 61000-4-5)
• ʻO ke ʻano maʻamau o ka lekiō (e pili ana i ka IEC 61000-4-6)
• ʻO ke kahua mākēneki mana-frequency (hōʻike IEC 61000-4-8)
• Hōʻoia hana

8. Hoʻohui 3 annex: annex G (informative) Unuhi kaha palekana;hoʻohui H (normative) ʻO ke ala ʻē aʻe no ka loiloi ʻana i ka pahu wai i hoʻoponopono ʻia a i ʻole i hoʻoheheʻe ʻia i ka ʻakika alakaʻi a i ʻole nā ​​pahu nickel cadmium;annex I (normative): papahana hoʻāʻo no nā ʻeke metala-ea hiki ke hoʻouka hou ʻia.

E akahele

ʻAʻole ʻike hou ʻia ka palapala hōʻoia UL 1642 no nā kelepona no nā pā ma lalo o ka palapala hōʻoia UL1973.
