Eia mai ka hardcore! E lawe iā ʻoe i kahi ʻike piha o ka hoʻāʻo ʻana i ka nail nail penetration test.
ʻO nā kaʻa ikehu hou ke alakaʻi o ka hoʻomohala ʻana i nā kaʻa e hiki mai ana, a ʻo kekahi o nā mea nui o nā kaʻa ikehu hou ʻo ia ka pā uila. I kēia manawa, ʻelua mau ʻano ma ka mākeke: ternary lithium a me lithium iron phosphate. ʻO wai o kēia mau ʻano pākahi ʻelua i ʻoi aku ka maʻalahi a me ka palekana? Ma mua, ua hāʻawi mai ka pā uila o BYD i kahi pane me kona hiki ke hana hou a me ka hōʻiliʻili ʻenehana hohonu. I kēia manawa, ua lanakila ka palekana kiʻekiʻe loa o ka pākahi lithium Kenergy i ka "Mount Everest" o ke kahua hoʻāʻo pākaukau - ka hoʻāʻo ʻana i ke kui. I kēia lā, e kamaʻilio wau e pili ana i ka palekana o nā pā lithium e pili ana i ka hoʻāʻo nail penetration o Kenergy lithium battery.
Ma mua o ka kamaʻilio ʻana e pili ana i ka hoʻāʻo nail penetration, e wehewehe mua wau i nā ʻano hoʻokolohua maʻamau o kēia manawa no ka palekana o ka pākaukau. I loko o nā koina maʻamau o ke aupuni no ka palekana o ka pākaukau, ʻo nā pōʻino i hoʻokumu ʻia e nā pihi mana o nā kaʻa uila, nā ʻeke pākahi, a i ʻole nā ʻōnaehana: (1) leakage, hiki ke alakaʻi i ka volta kiʻekiʻe o ka ʻōnaehana pākaukau a me ka hiki ʻole o ka insulation, e hoʻokau pololei ʻole i nā limahana uila. ka haʻalulu, ke ahi ʻōnaehana pākahi, a me nā pōʻino ʻē aʻe; (2) ke ahi, ka mea e puhi pono ai i ke kino kanaka; (3) pahū, e hoʻopilikia pololei ana i ke kino o ke kanaka, e like me nā wela wela, nā ʻeha haʻalulu, a me nā ʻeha ʻāpana pahū, a pēlā aku; (4) ka uila uila, ka mea i hana ʻia e ke au e hele ana ma ke kino o ke kanaka.
No ke aha e pono ai ka ho'āʻo ʻana i ke kui?
Wahi a nā ʻikepili kūpono, e lawe ana i nā pōʻino i hala o nā kaʻa ikehu hou ma ke ʻano he laʻana, ʻo ka hapa nui o nā ulia puhipuhi kuʻuna e pili ana i nā pihi pili pili i ka holo ʻana o ka wela o nā pūnāwai. No laila, he aha ka thermal runaway? ʻO ka holo wela wela o kahi pākaukau e pili ana i ke kūlana kahi i ʻoi aku ka kiʻekiʻe o ka nui o ka wela o nā hopena kemika o loko o ka pākaukau ma mua o ka nui o ka wela. ʻO ka nui o ka wela e hōʻiliʻili ai i loko o ka pākaukau, e piʻi wikiwiki ana ka wela o ka pākaukau, a i ka hopena i ke ahi a pahū paha.
Hiki i ka ho'āʻo ʻana i ke kui ke hoʻohālikelike i nā kaapuni pōkole o loko a me waho e alakaʻi ai i ka holo wela. I kēia manawa, ʻelua kumu nui o ka holo ʻana o ka wela: ʻo kekahi ke kumu mechanical a me nā kumu uila (e like me ke komo ʻana o ke kui, ka hui ʻana, a me nā pōʻino ʻē aʻe); ʻo ka mea ʻē aʻe he kumu electrochemical (e like me ka overcharging, fast charging, spontaneous short circuit, etc.). Ma hope o ka holo ʻana o ka wela o kahi pākahiko hoʻokahi, hoʻouna ʻia ia i nā cell pili, a laila pālahalaha ma kahi ākea, a hiki i ka hopena o nā pōʻino palekana.
ʻAʻole paʻakikī ke kaʻina hana o ka nail penetration test. Wahi a ke kaʻina hana hoʻāʻo nail penetration i ʻōlelo ʻia ma ke kūlana aupuni, pono e hoʻopiha piha ʻia ka pākaukau, a hoʻohana ʻia kahi nila kila tungsten e komo pono i ka pā. E hoʻokuʻu ʻia ka ikehu holoʻokoʻa o ka pākaukau ma o ka nail penetration point i kahi manawa pōkole. Noho ka nila kila i loko o ka pākaukau, a mālama ʻia no hoʻokahi hola. Manaʻo ʻia he kūpono inā ʻaʻohe ahi a pahū. Ma waena o nā ho'āʻo ʻoi aku ma mua o 300 no ka palekana pākaukau lithium, ʻike ʻia ka hōʻike nail penetration ma ke ʻano he mea paʻakikī loa a paʻakikī hoʻi e hoʻokō. Eia nō naʻe, ua lanakila ʻo Kenergy lithium battery i kahi hoʻokolohua koʻikoʻi loa.
ʻO "Super Safety" ka hiʻohiʻona nui loa o Kenergy lithium battery, a ʻo nā hopena hōʻike hoʻi e hōʻoia i kēia. Ma hope o ka hoʻokomo piha ʻia ʻana e ka nila, ʻo ke kiʻekiʻe kiʻekiʻe o ka wela wela o ka pā uila lithium Kenergy ma lalo o 50 ° C, ʻaʻohe ahi a pahū, ʻaʻohe uahi. Hiki ke ʻike ʻia he palekana loa kēia pākaukau ma lalo o nā kūlana kaapuni pōkole.

ʻO ka lithium iron phosphate prismatic pākahiko i hoʻohana ʻia no ka hoʻohālikelike hoʻohālikelike ʻaʻole i hoʻopuka i kahi lapalapa ākea, akā ua nui ka uahi mānoanoa, a ua maopopo loa ka hoʻololi ʻana o ka mahana. He mea weliweli loa ka hana ana o kekahi puliki lithium ternary: ua komo ke kinikini i ka manawa o ke komo ana o ke kui, ua oi aku ka wela o ka ili o ka paila ma mua o 500°C, a laila ua wela i ke ahi a pahū. Inā loaʻa kēia i ka wā kaʻa maoli, ʻoi aku ka nui o ka pilikia palekana.
Nā kiʻi hopena hoʻāʻo Lithium Iron Phosphate hoʻokūkū
Ua ʻike ʻia ka pākaukau lithium Kenergy e ka ʻoihana a me nā mea kūʻai aku.
ʻO ka hoʻāʻo ʻana o ka nail nail ke kumu o ka ʻoihana o Kenergy lithium battery. Loaʻa i kā mākou huahana nā hiʻohiʻona o ka ikaika nui, super endurance, super life, super power, a super cool resistance, ʻo ia ka pōhaku kihi o ke alakaʻi mau ʻana o Kenergy lithium battery. I ka manawa like, ke hoʻomau nei ka pākaukau lithium Kenergy i ke kūʻai wela, ʻo ia ka hōʻoia nui o nā mea kūʻai aku a me ka mākeke i ka ʻoihana.
Welina mai iā KELAN Lithium Battery. ʻO kā mākou kikowaena mana lawe lima,LiFePO4 Lithium Battery, aPākuʻi EV māmānā pūnaewele hiʻohiʻona a pau i hala i ka hoʻokolohua nail penetration. E hoʻohana iā lākou me ka hilinaʻi.
