Bazi rekuchengetedza magetsi muChina rave kuita danho guru rekuchengetedza. Musi wa1 Nyamavhuvhu, 2025,GB 44240-2024 standard(Maseru echipiri e-lithium nemabhatiri anoshandiswa mumagetsi ekuchengetedza simba-zvinodiwa zvekuchengetedza) zvakatanga kushanda zviri pamutemo. Uyu hausi mumwe mutemo chete; ndiwo wekutanga mutemo wekuchengetedza nyika weChina wakanangana nemabhatiri e-lithium-ion anoshandiswa mumasisitimu ekuchengetera simba (ESS)Kuchinja uku kunochinja kuchengetedzeka kubva pakusarudza kuenda pakuva chinhu chakakosha.
1. Iyi Standard GB 44240-2024 Inoshanda Papi?
Chiyero ichi chinofukidza mabhatiri e lithium nemapaketi mumabasa akasiyana-siyana eESS:
- ① Simba rekuchengetedza reTelecom
- ② Mwenje wepakati uye maaramu
- ③ Injini yakatanga kushanda zvakanaka
- ④ Masisitimu ezuva edzimba nemabhizimisi
- ⑤Kuchengetedza simba remagetsi pagrid(zviri pagrid uye zvisiri pagrid)
▲ Zvakakosha: Masisitimu akaongororwa kupfuura100 kWhMasisitimu madiki anowira zvakananga pasi peGB 44240-2024. Masisitimu madiki anotevera mwero weGB 40165 wakasiyana.
2. Nei "Zvinosungirwa" Zvichikosha
Izvi zvinoshandura zvinhu. GB 44240-2024 ine simba repamutemo uye zvinodiwa kuti munhu asvike pamusika. Kutevedzera mitemo hakuchinjiki. Inoenderanawo nemitemo mikuru yepasi rose (IEC, UL, UN), ichivimbisa kuti zvinhu zvinoenderana pasi rose. Chinonyanya kukosha ndechekuti inoda kuchengetedzeka kwakazara muhupenyu hwese hwebhatiri, kusanganisira dhizaini, kugadzirwa, kuyedzwa, kutakurwa, kuiswa, kushandiswa, uye kudzokororwa. Nguva "yekusadhura uye isina kuchengetedzeka" iri kusvika kumagumo.
3. Maitiro Ekuongorora Kuchengetedzeka Kwemabhatiri eLithium Akasimba
Mutemo uyu unorayira bvunzo dzekuchengetedza makumi maviri nenhatu, dzinofukidza masero, mamodule, uye masisitimu akazara. Miedzo mikuru inosanganisira:
- ⭐Kubhadharisa mari yakawandisa: Kuchaja kusvika 1.5x voltage ine muganho kweawa imwe (hapana moto/kuputika).
- ⭐Kumanikidzwa Kubuda Muchipatara: Dzorera kuchaja kune voltage yakatarwa (hapana thermal runaway).
- ⭐Kupinda kwenzara: Kutevedzera mabhurugwa mapfupi emukati nekuisa tsono zvishoma nezvishoma (hapana kupisa kunobuda).
- ⭐Kushandiswa Zvisina Kunaka Kwekupisa: Kuchengetedzwa pa130°C kweawa imwe chete.
- ⭐Michina & Zvakatipoteredza: Miedzo yekudonha, kupwanya, kudonha, kudonha, kudedera, uye tembiricha.
Chinyorwa chakatsaurirwa chinotsanangura bvunzo dzekupisa dzinobva mumhepo, zvichiratidza zvinhu zvinokonzeresa kupisa, nzvimbo dzekuyera, zvinodiwa pakukundikana (sekukwira nekukurumidza kwekushisa kana kudonha kwemagetsi), uye zvimwe zvinhu.
4. Masisitimu Akasimba Ekutarisira Mabhatiri (BMS)
Zvinodiwa neBMS zvava kusungirwa. Masisitimu anofanira kusanganisira:
- ♦ Kudzora kuchaja kwemagetsi akawandisa/akawandisa
- ♦ Kuganhurirwa kwekubuda kwepasi pemagetsi
- ♦ Kudzora tembiricha yakawandisa
- ♦ Kuvharirwa kwesystem otomatiki mumamiriro ezvinhu ekutadza (hazvigadziriswe nevashandisi)
Mutemo uyu unosimudzira nzira yakakwana yekuchengetedzeka, uchikurudzira magadzirirwo anodzivirira kupararira kwekupisa kusingafadzi.
5. Zvinodiwa zvekunyora mabhatiri e lithium zvakajeka uye zvakasimba
Kuzivikanwa kwechigadzirwa kunowedzera kuoma. Mabhatiri nemapaketi anofanirwa kunge aine mazita echiChinese anogara aripo anoratidza:
- ①Zita, modhi, kugona, chiyero chesimba, voltage, miganhu yekuchaja
- ②Mugadziri, zuva, polarity, hupenyu hwakachengeteka, kodhi yakasiyana
- ③Mapepa ekunyorera anofanira kugara achidziya uye achiverengwa kwenguva refu. Mapaketi anodawo yambiro dzakajeka: "Musapwanya," "Dzivisai Kupisa Kwakanyanya," "Regai Kushandisa Kana Muchizvimba."
6. Mhedziso
GB 44240-2024 inoratidza danho guru reChina rekuchengetedza indasitiri yayo iri kukura yekuchengetedza magetsi. Inoisa nhanho yepamusoro, ichisimudzira mhando uye kuvandudzwa kwekuchengetedza kwese kwese. Kune vagadziri vanovimba nemazano "asina mutengo wakaderera, asina kuchengetedzeka", mutambo wapera. Uyu ndiwo musimboti mutsva wekuvimbikaESSmuChina.
