Miyezo 5 yovomerezeka kwambiri pachitetezo cha batri (miyezo yapadziko lonse lapansi)

Batire ya lithiamu-ionmachitidwe ndi ovuta electrochemical ndi makina makina, ndipo chitetezo cha batire paketi n'kofunika mu magalimoto magetsi. Ku China "Zofunikira Zotetezera Magalimoto a Magetsi", zomwe zimanena momveka bwino kuti dongosolo la batri likufunika kuti lisagwire moto kapena kuphulika mkati mwa mphindi 5 pambuyo pa kutha kwa matenthedwe a batri monomer, ndikusiya nthawi yopulumukira kwa omwe akukhalamo.

(1) Chitetezo cha kutentha kwa mabatire amphamvu

Kutentha kochepa kungapangitse kuti batire isagwire bwino ntchito komanso kuwonongeka komwe kungachitike, koma nthawi zambiri sikubweretsa ngozi. Komabe, kuchulukitsitsa (kuchuluka kwa voteji) kungayambitse kuwonongeka kwa cathode ndi okosijeni wa electrolyte. Kutulutsa kopitilira muyeso (kutsika kwambiri kwamagetsi) kungayambitse kuwonongeka kwa mawonekedwe olimba a electrolyte (SEI) pa anode ndipo kungayambitse kutsekemera kwa zojambulazo zamkuwa, kuwononga kwambiri batire.

(2) IEC 62133 muyezo

IEC 62133 (chitetezo choyezera mabatire ndi ma cell a lithiamu-ion) ndi chofunikira pachitetezo poyesa mabatire achiwiri ndi ma cell okhala ndi ma electrolyte amchere kapena osakhala acidic. Amagwiritsidwa ntchito kuyesa mabatire omwe amagwiritsidwa ntchito pamagetsi osunthika ndi zinthu zina, kuthana ndi zoopsa zamakina ndi zamagetsi komanso zovuta zamakina monga kugwedezeka ndi kugwedezeka komwe kumatha kuwopseza ogula ndi chilengedwe.

(3)UN/DOT 38.3

UN / DOT 38.3 (T1 - T8 mayesero ndi UN ST/SG/AC.10/11/Rev. 5), yophimba mapaketi onse a batri, maselo a lithiamu zitsulo ndi mabatire kuti ayese chitetezo choyendera. Muyezo woyeserera uli ndi mayeso asanu ndi atatu (T1 - T8) omwe amayang'ana kwambiri zoopsa zamayendedwe.

(4) IEC 62619

IEC 62619 (Safety Standard for Secondary Lithium Battery and Battery Packs), muyezo umatchula zofunikira zachitetezo pamabatire pamagetsi ndi mafakitale ena. Zofunikira pakuyesa zimagwira ntchito pazoyima komanso zoyendetsedwa ndi magetsi. Mapulogalamu osasunthika akuphatikiza matelefoni, magetsi osasokoneza (UPS), makina osungira mphamvu zamagetsi, zosinthira zofunikira, mphamvu zadzidzidzi ndi zina zofananira. Ntchito zoyendetsedwa ndi mphamvu zikuphatikiza ma forklift, ngolo za gofu, magalimoto oyendetsedwa ndi makina (AGVs), njanji, ndi zombo (kupatula magalimoto apamsewu).

(5)UL 2580x

UL 2580x (UL Safety Standard for Electric Vehicle Batteries), yopangidwa ndi mayesero angapo.

Mzere Wachidule Wa Battery Yamakono: Mayesowa amayendetsedwa ndi zitsanzo zodzaza kwathunthu. Zitsanzozo ndizofupikitsidwa pogwiritsa ntchito kukana kwathunthu kwa ≤ 20 mΩ. Kuyatsa kwa Spark kumazindikira kukhalapo kwa mpweya woyaka pachitsanzo ndipo palibe zizindikiro za kuphulika kapena moto.

Kuphwanya kwa Battery: Thamangani pa chitsanzo chokhala ndi chaji chonse ndipo yerekezerani zotsatira za ngozi yagalimoto pa EESA kukhulupirika. Mofanana ndi kuyesa kwafupipafupi, kuyatsa kwa spark kumazindikira kukhalapo kwa mpweya woyaka m'chitsanzocho ndipo palibe chizindikiro cha kuphulika kapena moto. Palibe mpweya wapoizoni umene umatulutsidwa.

Finyani Maselo a Battery (Oyima): Thamangani pa chitsanzo chodzaza kwathunthu. Mphamvu yomwe imagwiritsidwa ntchito poyesa kufinya iyenera kukhala yochepera 1000 kulemera kwa selo. Kuzindikira kuyatsa kwa Spark ndikofanana ndi komwe kumagwiritsidwa ntchito poyesa kufinya.

(6) Zofunikira Zachitetezo Pamagalimoto Amagetsi (GB 18384-2020)

Zofunikira Zachitetezo Pamagalimoto Amagetsi" ndi mulingo wadziko lonse wa People's Republic of China womwe udakhazikitsidwa pa Januware 1, 2021, womwe umafotokoza zofunikira zachitetezo ndi njira zoyesera zamagalimoto amagetsi.
