Chikamu chekuchengetedza magetsi cheChina chakangotora danho rakakura rekuchengetedza. Musi waNyamavhuvhu 1, 2025, iyoGB 44240-2024 yakajairwa(Secondary lithium masero uye mabhatiri anoshandiswa mumagetsi ekuchengetedza simba masisitimu-Kuchengetedza zvinodiwa) zvakatanga kushanda. Iyi haingori imwe gwara; ndiyo yekutanga yekuChina inosungirwa yenyika kuchengetedza chiyero chakanangana ne lithium-ion mabhatiri anoshandiswa mukatimasisitimu ekuchengetedza simba (ESS). Kufamba uku kunoshandura kuchengetedzwa kubva pakusarudza kuenda kune kwakakosha.
1. Iyi Standard GB 44240-2024 Inoshanda kupi?
Iyo chiyero inovhara lithium mabhatiri uye mapaketi mune akasiyana ESS application:
- ① Telecom backup simba
- ② Central emergency light & alarms
- ③ Yakagadziriswa injini kutanga
- ④ Nzvimbo dzekugara uye dzekutengesa solar system
- ⑤Grid-scale simba rekuchengetedza(zvese zviri pa-grid & off-grid)
▲ Crucially: Masisitimu akayerwa pamusoro100 kWhinowira zvakananga pasi peGB 44240-2024. Madiki masisitimu anotevera akaparadzana GB 40165 standard.
2. Nei “Zvinosungirwa” Zvichikosha
Uyu ndiwo mutambo wekuchinja. GB 44240-2024 inotakura simba repamutemo uye zvinodiwa pamusika. Kuteerera hakugone kutaurirana. Iyo zvakare inopindirana nehukuru hwepasirese zviyero (IEC, UL, UN), kuve nechokwadi chekuenderana pasi rose. Kunyanya kukosha, inoisa yakazara kuchengetedza zvinodiwa mukati mese kwese kwehupenyu hwebhatiri kutenderera, kusanganisira dhizaini, kugadzira, kuyedza, kufambisa, kuisirwa, kushanda, uye kudzokorodza. Nguva ye "yakachipa uye isina kuchengetedzeka" iri kusvika kumagumo.
3. Rigorous Lithium Battery Safety Testing Standards
Iyo yakajairwa inoraira makumi maviri nematatu chaiwo ekuchengetedza bvunzo, anovhara maseru, mamodule, uye akazara masisitimu. Miedzo yakakosha inosanganisira:
- ⭐Overcharge: Kuchaja ku1.5x iyo inogumira voltage kweawa 1 (hapana moto / kuputika).
- ⭐Kumanikidzwa Kuburitsa: Reverse charger kune set voltage (hapana thermal runaway).
- ⭐Kupinza Kwezvipikiri: Kutevedzera zvikabudura zvemukati zvine ultra-slow inopinza tsono (hapana thermal runaway).
- ⭐Thermal Abuse: Kuratidzira ku130 ° C kweawa imwe.
- ⭐Mechanical & Environmental: Donhedza, kupwanya, kukanganisa, vibration, uye tembiricha yebhasikoro bvunzo.
A appendikisi yakatsaurirwa inotsanangura kupisa kwekumhanya kwekuyedzwa, kutsanangura zvinokonzeresa, zviyero zvekuyerwa, maitiro ekutadza (seanokurumidza spikes tembiricha kana madonhwe emagetsi), uye ruzivo.
4. Yakasimba Battery Management Systems (BMS)
Zvinodiwa zveBMS zvino zvinosungirwa. Masisitimu anofanirwa kusanganisira:
- ♦ Over-voltage/over-current charge control
- ♦ Under-voltage discharge cut-off
- ♦ Over-temperature control
- ♦ Otomatiki sisitimu yekuvhara-pasi mumamiriro ekukanganisa (isina-kugadziriswa nevashandisi)
Iyo chiyero inosundira kune yakazara nzira yekuchengeteka, inokurudzira dhizaini inodzivirira kupisa kwemhepo kupararira.
5. Clearer & Tougher lithium battery labeling zvinodiwa
Kuzivikanwa kwechigadzirwa kunowedzera kusimba. Mabhatiri nemapaketi anofanirwa kuve neanogara eChinese mavara anoratidza:
- ①Zita, modhi, kugona, chiyero chesimba, voltage, miganhu yekuchaja
- ②Mugadziri, zuva, polarity, yakachengeteka hupenyu, yakasarudzika kodhi
- ③Mapepa anofanirwa kumira nekupisa uye kuramba achiverengwa kwenguva refu. Mapaketi anodawo yambiro yakajeka: "Hapana Disassembly," "Dzivisa Kupisa Kwepamusoro," "Misa Kushandisa Kana Kuzvimba."
6. Mhedziso
GB 44240-2024 inocherekedza danho reChina rakananga kune inosungirwa, yakakwirira-yepamusoro kuchengetedzwa kweindasitiri yayo iri kukura yekuchengetedza simba. Iyo inoisa yakakwira bar, yekutyaira mhando uye kuchengetedza kukwidziridzwa mukati mebhodhi. Kune vagadziri vanovimba ne "yakaderera-mutengo, yakaderera-chengetedzo" maitiro, mutambo wapera. Iyi ndiyo nheyo itsva yekuvimbikaESSmuChina.
