Overview

UL 1973:2022 yakaburitswa musi wa25 Kukadzi. Iyi vhezheni yakavakirwa pamazano maviri ekunyorwa akapihwa muna Chivabvu naGumiguru we2021. Iyo yakagadziridzwa mwero inowedzera huwandu hwayo, kusanganisira mota mubatsiri simba system (semuenzaniso kuvhenekera nekutaurirana).

Kuchinja kwekusimbisa

1.Append 7.7 Transformer: transformer yebhatiri system ichapihwa chitupa pasi pe UL 1562 uye UL 1310 kana zviyero zvakakodzera. Low voltage inogona kupihwa chitupa pasi pe26.6.

2.Update 7.9: Dziviriro Dzekutenderera uye Kudzora: bhatiri system ichapa switch kana breaker, iyo shoma inodiwa kuva 60V pane 50V. Kuwedzera kunodiwa kuraira kweiyo overcurrent fuse

3.Update 7.12 Masero (mabhatiri uye electrochemical capacitor): Kune rechargeable Li-ion masero, kuedza pasi peannex E kunodiwa, pasina kufunga nezve UL 1642. Masero anodiwawo kuti aongororwe kana akasangana nezvinodiwa zvekugadzirwa kwakachengeteka, sezvinhu uye nzvimbo ye insulator, kufukidzwa kweanode uye cathode, nezvimwe.

4.Append 16 High Rate Charge: Ongorora kuchengetedzwa kwekuchaja kwebhatiri system nepamusoro pekuchaja kwakanyanya. Inoda kuyedza mu120% yehuwandu hwekuchaja.

5.Append 17 Short Circuit Test: Ita chidimbu chechidimbu chekuongorora kwebheteri modules inoda kuiswa kwefaira kana kuchinja.

6.Append 18 Overload Under Discharge: Ongorora bhatiri system kugona nekuremerwa pasi pekubuda. Pane mamiriro maviri ekuedzwa: yekutanga iri mukuremerwa pasi pekubudiswa umo ikozvino yakakwirira kudarika yakarongwa yakawanda yekuburitsa ikozvino asi yakaderera pane ikozvino yeBMS overcurrent kudzivirira; yechipiri yakakwirira kudarika BMS pamusoro pekuchengetedzwa kwemazuva ano asi yakaderera pane level 1 yekudzivirira ikozvino.

7.Append 27 Electromagnetic Immunity Test: yakazara 7 bvunzo sezvinotevera:

• Electrostatic discharge (referensi IEC 61000-4-2)
• Radio-frequency electromagnetic field (referensi IEC 61000-4-3)
• Inokurumidza kuchinjika / kuputika kusadzivirirwa (referensi IEC 61000-4-4)
• Surge kudzivirirwa (referensi IEC 61000-4-5)
• Radio-frequency common mode (referensi IEC 61000-4-6)
• Simba-frequency magnetic field (referensi IEC 61000-4-8)
• Operational verification

8.Enderedza 3 annex: annex G (inozivisa) Kudzivirirwa kwechiratidzo chekushandura; annex H (normative) Imwe nzira yekuongorora vharafu inodzorwa kana mhepo inotungamira asidhi kana nickel cadmium mabhatiri; annex I (normative) : chirongwa chekuyedza chemabhatiri esimbi-mhepo anochajika.

Kuchenjerera

UL 1642 chitupa chemasero hachichazivikanwa kumabhatiri pasi peUL1973 certification.
