Gawo losungiramo magetsi ku China langochita bwino kwambiri. Pa Ogasiti 1, 2025, aGB 44240-2024 muyezo(Maselo achiwiri a lithiamu ndi mabatire omwe amagwiritsidwa ntchito pamagetsi osungira mphamvu zamagetsi-Zofunikira zachitetezo) zidayamba kugwira ntchito. Ichi sichitsogozo china chabe; ndiye mulingo woyamba wachitetezo ku China wofunikira makamaka kutsata mabatire a lithiamu-ion omwe amagwiritsidwa ntchitomakina osungira mphamvu (ESS). Kusunthaku kumasintha chitetezo kuchoka pachosankha kupita chofunikira.
1. Kodi Standard GB 44240-2024 Imagwira Ntchito Kuti?
Muyezo umakwirira mabatire a lithiamu ndi mapaketi mumitundu yosiyanasiyana ya ESS:
- ① Mphamvu zosunga zobwezeretsera za Telecom
- ② Kuyatsa kwadzidzidzi kwapakati & ma alarm
- ③ Injini yokhazikika yoyambira
- ④ Makina adzuwa okhala ndi malonda
- ⑤Grid-scale mphamvu yosungirako(onse pa-grid & off-grid)
▲ Mwachidule: Machitidwe adavotera100 kwkugwa mwachindunji pansi pa GB 44240-2024. Makina ang'onoang'ono amatsata muyezo wosiyana wa GB 40165.
2. N'chifukwa Chiyani "Kuvomerezedwa" Kufunika
Izi ndizosintha masewera. GB 44240-2024 imanyamula mphamvu zamalamulo komanso zofunikira zopezera msika. Kutsatira sikungakambirane. Imagwirizananso ndi miyezo yayikulu yapadziko lonse lapansi (IEC, UL, UN), kuwonetsetsa kuti ikugwirizana padziko lonse lapansi. Chofunika kwambiri, chimakhazikitsa zofunikira zachitetezo chokwanira pa nthawi yonse ya moyo wa batri, kuphatikiza kupanga, kupanga, kuyesa, mayendedwe, kukhazikitsa, kugwira ntchito, ndi kukonzanso. Nthawi ya "zotsika mtengo ndi zosatetezeka" ikutha.
3. Miyezo Yoyesa Chitetezo cha Batri ya Lithium
Muyezowu umapereka mayeso 23 apadera achitetezo, ma cell ophimba, ma module, ndi machitidwe athunthu. Mayeso ofunikira ndi awa:
- ⭐Kuchulukitsa: Kulipiritsa kwa 1.5x malire amagetsi kwa ola la 1 (palibe moto / kuphulika).
- ⭐Kutulutsa Mokakamizika: Bwezeretsani kulipiritsa kukhala voteji yokhazikitsidwa (palibe kuthawa kwamafuta).
- ⭐Kulowetsa Msomali: Kuyerekeza akabudula amkati ndikulowetsa singano pang'onopang'ono (palibe kuthawa kwamafuta).
- ⭐Kutentha Kwambiri: Kuwonekera kwa 130 ° C kwa ola limodzi.
- ⭐Zimango & Zachilengedwe: Kugwetsa, kuphwanya, kukhudza, kugwedezeka, ndi mayeso oyendetsa njinga.
Zowonjezera zodzipatulira zimafotokozera za kuyezetsa kwa kutentha, kutchula zoyambitsa, zoyezera, njira zolepherera (monga kutentha kwachangu kapena kutsika kwamagetsi), ndi tsatanetsatane.
4. Njira Zamphamvu Zowongolera Battery (BMS)
Zofunikira za BMS tsopano ndizofunikira. Dongosolo liyenera kukhala:
- ♦ Kuwongolera kwamphamvu kwambiri / kupitilira panopa
- ♦ Kudula kwa undervoltage discharge
- ♦ Kuwotcha kwambiri
- ♦ Makina otsekera otsekera pamikhalidwe yolakwika (yosasinthika ndi ogwiritsa ntchito)
Muyezowu umakankhira njira yotetezeka, yolimbikitsa mapangidwe omwe amalepheretsa kufalikira kwa kutentha.
5. Zomveka bwino & Zovuta zolembera batire la lithiamu
Chizindikiritso cha malonda chimakhala chokhwima. Mabatire ndi mapaketi ayenera kukhala ndi zilembo zaku China zokhazikika:
- ①Dzina, chitsanzo, mphamvu, mphamvu yamagetsi, magetsi, malire a ndalama
- ②Wopanga, tsiku, polarity, moyo wotetezeka, code yapadera
- ③Zolemba ziyenera kupirira kutentha komanso kukhala zomveka kwa nthawi yayitali. Mapaketi amafunikanso machenjezo omveka bwino: "Palibe Disassembly," "Pewani Kutentha Kwambiri," "Lekani Kugwiritsa Ntchito Ngati Kutupa."
6. Mapeto
GB 44240-2024 ikuwonetsa gawo lotsimikizika la China kupita kuchitetezo chovomerezeka, chapamwamba pamakampani omwe akukula kwambiri osungira mphamvu. Imayika mipiringidzo yayikulu, kuyendetsa bwino komanso kukweza chitetezo pagulu lonselo. Kwa opanga omwe amadalira njira "zotsika mtengo, zotsika mtengo", masewerawa atha. Izi ndiye maziko atsopano odalirikaESSku China.
