UL 1973:2022 waxaa la daabacay 25-kii Febraayo.Noocani waxa uu ku salaysan yahay laba talo oo qabyo ah oo la soo saaray May iyo Oktoobar 2021. Heerarka wax laga beddelay waxa uu ballaadhiyaa baaxaddiisa, oo ay ku jiraan nidaamka tamarta kaaliyaha baabuurta (tusaale iftiiminta iyo xidhiidhka).

Beddelka xoojinta

1.Append 7.7 Transformer: Transformer ee nidaamka batteriga waa in lagu caddeeyaa UL 1562 iyo UL 1310 ama heerarka la xiriira.Danab yar ayaa lagu shahaado ka qaadan karaa 26.6.

2.Update 7.9: Ilaalinta Wareegyada iyo Xakamaynta: Nidaamka batteriga waa inuu bixiyaa beddelka ama jabiyaha, ugu yaraan kaas oo loo baahan yahay inuu noqdo 60V halkii 50V.Shuruudaha dheeraadka ah ee tilmaamaha loogu talagalay fiyuuska xad dhaafka ah

3.Update 7.12 Unugyada (Batteries and electrochemical capacitor): Unugyada Li-ion ee dib loo buuxin karo, waxaa loo baahan yahay in la tijaabiyo lifaaqa E, iyada oo aan la tixgelinayn UL 1642. Insulator, daboolida anode iyo cathode, iwm.

4.Append 16 Kharashka Heerka Sare: Qiimee ilaalinta dallacaadda ee nidaamka batteriga oo leh in ka badan dallacaadda ugu badan ee hadda.Waxa loo baahan yahay in lagu tijaabiyo 120% ee heerka ugu badan ee dallacaadda.

5.Append 17 Tijaabada Wareegga Gaaban: Samee tijaabada wareegga gaaban ee qaybaha batteriga ee u baahan rakibidda ama isbeddelka.

6.Append 18 Overload Under Discharge: Qiimee awoodda nidaamka batteriga ee culeyska hoostiisa.Waxaa jira laba shuruudood oo tijaabada ah: marka hore waa culeys xad dhaaf ah oo la sii daayo kaas oo hadda ka sarreeya heerka ugu sarreeya ee hadda jira laakiin ka hooseeya kan hadda ilaalinta xad-dhaafka ah ee BMS;ka labaad ayaa ka sarreeya BMS ilaalinta hadda jirta laakiin waxa uu ka hooseeya heerka 1 ilaalinta hadda.

7.Append 27 Imtixaanka Xakamaynta Electromagnetic: gabi ahaanba 7 imtixaan sida soo socota:

• Dheecaan elektrostatic ah (tixraac IEC 61000-4-2)
• Goobta korantada-soo noqnoqda ee raadiyaha (tixraac IEC 61000-4-3)
• Xasaanadda degdegga ah ee ku meel gaadhka ah/qarxinta (tixraac IEC 61000-4-4)
• Difaaca sare (tixraac IEC 61000-4-5)
• Habka caadiga ah ee soo noqnoqda raadiyaha (tixraac IEC 61000-4-6)
• Goobta magnetka-soo noqnoqda awoodda (tixraac IEC 61000-4-8)
• Xaqiijinta hawlgalka

8. Lifaaqa 3 lifaaqa: lifaaqa G (warbixin) tarjumaadda calaamadaynta badbaadada;lifaaqa H (caadi ah) Habka beddelka ah ee qiimaynta waalka nidaamsan ama hawo-mareen baytariyada cadmium ee nikkel;lifaaqa I (caadi): barnaamijka tijaabada ee baytariyada birta-hawada si farsamaysan dib loogu dallaci karo.
