Gawo losungira mphamvu ku China langoyamba kumene kuchita bwino kwambiri pa chitetezo. Pa Ogasiti 1, 2025,Muyezo wa GB 44240-2024(Ma cell achiwiri a lithiamu ndi mabatire omwe amagwiritsidwa ntchito mu makina osungira mphamvu zamagetsi - Zofunikira pachitetezo) adayamba kugwira ntchito mwalamulo. Izi si malangizo ena okha; ndi muyezo woyamba wofunikira wachitetezo cha dziko ku China womwe umayang'ana makamaka mabatire a lithiamu-ion omwe amagwiritsidwa ntchito mumakina osungira mphamvu (ESS)Kusunthaku kumasintha chitetezo kuchoka pa chinthu chosankha kupita pa chinthu chofunikira kwambiri.
1. Kodi Standard GB 44240-2024 iyi ikugwira ntchito kuti?
Muyezowu umaphimba mabatire a lithiamu ndi mapaketi m'magwiritsidwe osiyanasiyana a ESS:
- ① Mphamvu yosungira zinthu pa telefoni
- ② Magetsi apakati ndi ma alamu
- ③ Kuyambitsa injini kokhazikika
- ④ Makina a dzuwa okhala m'nyumba ndi m'mabizinesi
- ⑤Kusungira mphamvu pa gridi(onse pa gridi ndi kunja kwa gridi)
▲ Chofunika kwambiri: Machitidwe adavotera kuposa100 kWhKugwera pansi pa GB 44240-2024. Makina ang'onoang'ono amatsatira muyezo wosiyana wa GB 40165.
2. Chifukwa Chake "Chofunika" Chili Chofunika
Izi ndi zosintha zinthu. GB 44240-2024 ili ndi mphamvu zalamulo komanso zofunikira pakupeza msika. Kutsatira malamulo sikungakambirane. Ikugwirizananso ndi miyezo yayikulu yapadziko lonse lapansi (IEC, UL, UN), kuonetsetsa kuti ikugwirizana padziko lonse lapansi. Chofunika kwambiri, imalimbikitsa zofunikira zonse zachitetezo pa moyo wonse wa batri, kuphatikizapo kapangidwe, kupanga, kuyesa, mayendedwe, kuyika, kugwiritsa ntchito, ndi kubwezeretsanso. Nthawi ya "yotsika mtengo komanso yosatetezeka" ikutha.
3. Miyezo Yoyesera Chitetezo cha Batri ya Lithium Yolimba
Muyezowu umafuna mayeso 23 apadera achitetezo, omwe amaphimba maselo, ma module, ndi machitidwe onse. Mayeso ofunikira akuphatikizapo:
- ⭐Kulipiritsa ndalama zambiri: Kuchaja mpaka 1.5x mphamvu yamagetsi yokhazikika kwa ola limodzi (palibe moto/kuphulika).
- ⭐Kutulutsidwa Mokakamizidwa: Kuchajanso kubweza ku voltage yokhazikika (popanda kuthawa kwa kutentha).
- ⭐Kulowa kwa Misomali: Kuyerekeza zovala zazifupi zamkati ndi singano yolowera pang'onopang'ono kwambiri (popanda kutentha kwambiri).
- ⭐Kugwiritsa Ntchito Matenthedwe Molakwika: Kutenthedwa kufika pa 130°C kwa ola limodzi.
- ⭐Makina ndi Zachilengedwe: Mayeso ogwetsa, kuphwanya, kukhudza, kugwedezeka, ndi kutentha.
Chowonjezera choperekedwa chimafotokoza za mayeso otha kutentha, kufotokoza zoyambitsa, malo oyezera, njira zolephera (monga kukwera kwa kutentha mwachangu kapena kutsika kwa magetsi), ndi zina zambiri.
4. Machitidwe Olimba Oyang'anira Mabatire (BMS)
Zofunikira za BMS tsopano ndi zofunika. Machitidwe ayenera kuphatikizapo:
- ♦ Kuwongolera mphamvu yamagetsi ochulukirapo/yamagetsi ochulukirapo
- ♦ Kudula kwa kutayira kwa under-voltage
- ♦ Kulamulira kutentha kwambiri
- ♦ Kutseka makina okha ngati pali vuto (ogwiritsa ntchito sangayikidwenso)
Muyezowu umalimbikitsa njira yonse yopezera chitetezo, kulimbikitsa mapangidwe omwe amaletsa kufalikira kwa kutentha komwe kumatuluka.
5. Zofunikira pakulemba zilembo za batri ya lithiamu yomveka bwino komanso yolimba
Kuzindikira zinthu kumakhala kovuta. Mabatire ndi mapaketi ayenera kukhala ndi zilembo zokhazikika zaku China zomwe zikusonyeza:
- ①Dzina, chitsanzo, mphamvu, kuchuluka kwa mphamvu, mphamvu zamagetsi, malire a mphamvu
- ②Wopanga, tsiku, polarity, nthawi yotetezeka, code yapadera
- ③Zolemba ziyenera kupirira kutentha ndipo zikhale zowerengeka kwa nthawi yayitali. Mapaketi amafunikanso machenjezo omveka bwino: "Osachotsa," "Pewani Kutentha Kwambiri," "Lekani Kugwiritsa Ntchito Ngati Muli ndi Matenda."
6. Mapeto
GB 44240-2024 ikuyimira sitepe yofunika kwambiri ya China yopita ku chitetezo chofunikira komanso chapamwamba pamakampani ake osungira mphamvu omwe akukula mwachangu. Ikukhazikitsa mipiringidzo yapamwamba, ikukweza ubwino ndi chitetezo m'njira zosiyanasiyana. Kwa opanga omwe amadalira njira "zotsika mtengo komanso zotetezeka", masewerawa atha. Iyi ndiye njira yatsopano yodalirika yopezera chitetezoESSku China.
