He aha nā ʻano pākahiko kaʻa uila i loaʻa?

ʻO nā pila kaʻa uila ka ʻāpana pipiʻi loa o ke kaʻa uila.

ʻO ke kumukūʻai kiʻekiʻe o nā kaʻa uila ʻoi aku ke kumukūʻai ma mua o nā ʻano wahie ʻē aʻe, kahi e hoʻolohi nei i ka hoʻohana nui ʻana o ka EV.

Lithium-ion
ʻO nā pila Lithium-ion ka mea kaulana loa. Me ka ʻole o ka hele ʻana i nā kikoʻī nui, hoʻokuʻu lākou a hoʻouka hou i ka wā e lawe ana ka electrolyte i nā ion lithium i hoʻopiʻi maikaʻi ʻia mai ka anode a i ka cathode, a ʻo ka hope. Eia nō naʻe, hiki ke ʻokoʻa nā mea i hoʻohana ʻia i loko o ka cathode ma waena o nā pila lithium-ion.

ʻEkolu mau ʻano kemika like ʻole ʻo LFP, NMC, a me NCA o nā pila Lithium-ion. Hoʻohana ʻo LFP i ka Lithium-phosphate ma ke ʻano he mea cathode; Hoʻohana ʻo NMC i ka Lithium, Manganese, a me Cobalt; a hoʻohana ʻo NCA iā Nickel, Cobalt a me Aluminium.

Nā Pōmaikaʻi o nā pila Lithium-ion:
● ʻOi aku ke kumu kūʻai o ka hana ʻana ma mua o nā pila NMC a me NCA.
● ʻOi aku ka lōʻihi o ke ola - hāʻawi i 2,500-3,000 mau pōʻaiapuni hoʻouka/hoʻokuʻu piha i hoʻohālikelike ʻia me 1,000 no nā pila NMC.
● E hoʻemi i ka wela i ka wā e hoʻouka ai i hiki iā ia ke hoʻomau i ka nui o ka mana i loko o ke kaʻina hoʻouka, e alakaʻi ana i ka hoʻouka wikiwiki me ka ʻole o ka hōʻino ʻana o ka pila.
● Hiki ke hoʻouka ʻia a hiki i ka 100% me ka liʻiliʻi o ka pōʻino o ka pila no ka mea he kōkua ia i ka hoʻoponopono ʻana i ka pila a hāʻawi i nā kuhi mamao pololei - Ua ʻōlelo ʻia nā mea nona ka Model 3 me kahi pila LFP e mālama i ka palena hoʻouka i hoʻonohonoho ʻia i 100%.

I ka makahiki i hala, ua hāʻawi maoli ʻo Tesla i kāna mau mea kūʻai aku Model 3 ma ʻAmelika i kahi koho ma waena o kahi pākahi NCA a i ʻole kahi pākahi LFP. ʻOi aku ka māmā o ka pākahi NCA he 117kg a hāʻawi i kahi mamao he 10 mile, akā ua lōʻihi ka manawa alakaʻi. Eia nō naʻe, paipai pū ʻo Tesla e hoʻopiha wale ʻia ka pākahi NCA i 90% o kona hiki. I nā huaʻōlelo ʻē aʻe, inā ʻoe e hoʻolālā e hoʻohana mau i ka laulā piha, ʻoi aku ka maikaʻi o ka LFP.

ʻO ka hydride nikala-metala
ʻO nā pila hydride nickel-metal (i hoʻopōkole ʻia i NiMH) wale nō ke koho ʻē aʻe i nā pila lithium-ion i kēia manawa ma ka mākeke, ʻoiai ke loaʻa pinepine ʻia nei i nā kaʻa uila hybrid (ʻo Toyota ka hapa nui) i kūʻē i nā kaʻa uila maʻemaʻe.

ʻO ke kumu nui o kēia, ʻo ka nui o ka ikehu o nā pila NiMH he 40% ka haʻahaʻa ma mua o nā pila lithium-ion.
