ʻO 5 mau kūlana mana loa no ka palekana pākaukau (nā kūlana papa honua)

ʻO ka pākaukau Lithium-ionʻO nā ʻōnaehana he ʻōnaehana electrochemical paʻakikī a me nā ʻōnaehana mechanical, a he mea koʻikoʻi ka palekana o ka pahu pākaukau i nā kaʻa uila. ʻO ka "Electric Vehicle Safety Requirements" o Kina, e hōʻike maopopo ana he pono ka ʻōnaehana ʻaʻole e puhi i ke ahi a pahū paha i loko o 5 mau minuke ma hope o ka holo ʻana o ka wela o ka monomer pākahi, e waiho ana i kahi manawa pakele no ka poʻe e noho ana.

(1) Palekana wela o nā pihi mana

Hiki i nā ha'aha'a ha'aha'a ke alaka'i i ka ha'aha'a ha'aha'a o ka pākaukau a me ka pō'ino, akā, 'a'ole ia e pilikia. Eia nō naʻe, hiki i ka hoʻonui ʻana (ke kiʻekiʻe kiʻekiʻe o ka volta) ke alakaʻi i ka decomposition cathode a me ka electrolyte oxidation. ʻO ka hoʻokuʻu ʻana (haʻahaʻa haʻahaʻa loa) hiki ke alakaʻi i ka decomposition o ka interface electrolyte solid (SEI) ma ka anode a hiki ke alakaʻi i ka oxidation o ka pahu keleawe, e hōʻino hou i ka pākaukau.

(2) IEC 62133 maʻamau

ʻO IEC 62133 (Ka maʻamau hoʻāʻo palekana no nā pā lithium-ion a me nā cell), kahi koi palekana no ka hoʻāʻo ʻana i nā pā lua a me nā cell i loaʻa nā electrolytes alkaline a i ʻole acidic. Hoʻohana ʻia ia e hoʻāʻo i nā pihi i hoʻohana ʻia i nā uila uila a me nā noi ʻē aʻe, e hoʻoponopono ana i nā pōʻino kemika a me ka uila a me nā pilikia mechanical e like me ka vibration a me ka haʻalulu e hoʻoweliweli paha i nā mea kūʻai aku a me ke kaiapuni.

(3)UN/DOT 38.3

UN / DOT 38.3 (T1 - T8 ho'āʻo a me UN ST/SG/AC.10/11/Rev. 5), e uhi ana i nā pūʻolo pila a pau, nā pūnaewele metala lithium a me nā pihi no ka hoʻāʻo ʻana i ka palekana. ʻO ka maʻamau hoʻāʻo he ʻewalu mau hoʻokolohua (T1 - T8) e kālele ana i nā pōʻino o ka halihali.

(4) IEC 62619

ʻO IEC 62619 (Safety Standard no Secondary Lithium Batteries and Battery Packs), ke kuhikuhi nei ka maʻamau i nā koi palekana no nā pā i ka uila a me nā noi ʻoihana ʻē aʻe. Pili nā koi hoʻāʻo i nā noi paʻa a me ka mana. Loaʻa i nā noi paʻa ke kelepona, nā lako mana hiki ʻole ke hoʻopau ʻia (UPS), nā ʻōnaehana mālama ikehu uila, ka hoʻololi pono, ka mana pilikia a me nā noi like. Loaʻa i nā noi ikaika nā forklifts, nā kaʻa kolepa, nā kaʻa alakaʻi automated (AGV), nā alahao, a me nā moku (koe nā kaʻa ma ke alanui).

(5)UL 2580x

UL 2580x (UL Safety Standard for Electric Vehicle Batteries), i loaʻa i kekahi mau hoʻokolohua.

Kaapuni Pokole Puka Kiʻekiʻe o kēia manawa: Ke holo nei kēia hoʻokolohua ma kahi laʻana i hoʻopiha piha ʻia. Hoʻopili pōkole ʻia ka hāpana me ka hoʻohana ʻana i ka pale kaapuni holoʻokoʻa o ≤ 20 mΩ. ʻIke ʻo Spark ignition i ka loaʻa ʻana o ke kinoea puhi ahi i loko o ka laʻana a ʻaʻohe hōʻailona o ka pahū a i ʻole ke ahi.

Pākuʻi Kaʻa: Holo ma kahi laʻana i hoʻopiha piha ʻia a hoʻohālikelike i nā hopena o kahi kaʻa i ka pono EESA. E like me ka ho'āʻo kaapuni pōkole, ʻike ʻia ka ʻā ʻana o ke ahi i ka hiki ʻana mai o nā ʻike kinoea i loko o ka hāpana a ʻaʻohe hōʻike o kahi pahū a i ʻole ke ahi. ʻAʻole hoʻokuʻu ʻia nā kinoea ʻona.

ʻO ka Pūnaewele Pūnaewele Squeeze (Vertical): Holo ma kahi laʻana i hoʻopiha piha ʻia. Pono e kaupalena ʻia ka ikaika i hoʻohana ʻia i ka hoʻāʻo ʻana i ka 1000 mau manawa o ke kaumaha o ke kelepona. Ua like ka ʻike ʻana i ka Spark ignition me ka mea i hoʻohana ʻia ma ka hoʻāʻo squeeze.

(6) Nā Koina Palekana no nā Kaʻa Uila (GB 18384-2020)

ʻO nā koi palekana no nā kaʻa uila" he kūlana aupuni o ka People's Republic of China i hoʻokō ʻia ma Ianuali 1, 2021, e kuhikuhi ana i nā koi palekana a me nā ʻano hoʻāʻo no nā kaʻa uila.
