ʻO ka mana nui, ka mana nui, ka liʻiliʻi liʻiliʻi, ke kaumaha māmā, ka hana maʻalahi maʻalahi, a me ka hoʻohana ʻana i nā ʻāpana liʻiliʻi he mea paʻakikī i ka hoʻolālā ʻana i nā pā uila EV. ʻO ka kilowatt-hour (kWh) i loaʻa pono e hāʻawi i ka laulā kiʻekiʻe, akā ma ke kumu kūʻai kūpono no ka hana ʻana. ʻO ka hopena, e ʻike pinepine ʻoe i nā wehewehe ʻana o ka pūʻulu pākaukau e hōʻike ana i kā lākou mau kumukūʻai hana, me nā helu, mai $240 a $280/kWh i ka wā hana, no ka laʻana.
ʻAe, a mai poina kākou i ka palekana. E hoʻomanaʻo i ka Samsung Galaxy Note 7 fiasco i kekahi mau makahiki i hala, a me ka EV pākahiko e like me ke ahi kaʻa a me Chernobyl like meltdowns. pack e pale aku i ka hoʻā ʻana o kekahi kelepona i kekahi, ʻo kekahi, a me nā mea ʻē aʻe, e hoʻohui i ka paʻakikī o ka hoʻomohala ʻana i ka pā uila EV. Ma waena o lākou, ʻo Tesla kekahi mau pilikia.
ʻOiai he ʻekolu mau ʻāpana nui o ka pā uila EV: ʻo nā ʻāpana pākaukau, kahi ʻōnaehana hoʻokele pākaukau, a me kekahi ʻano pahu a pahu paha e hoʻopaʻa pū ai iā lākou, i kēia manawa, e nānā wale mākou i nā pihi a pehea lākou i ulu ai me Tesla, akā, he pilikia no Toyota.
ʻO ka pahu cylindrical 18650 he pahu lithium-ion me ke anawaena o 18 mm, ka lōʻihi o 65 mm a me ke kaumaha ma kahi o 47 grams. Ma ka volts nominal o 3.7 volts, hiki i kēlā me kēia pākaukau ke hoʻouka a hiki i 4.2 volts a hoʻokuʻu i ka haʻahaʻa. e like me 2.5 volts, e mālama ana i ka 3500 mAh i kēlā me kēia kelepona.
E like me ka electrolytic capacitors, Tesla ka uila kaʻa pākahi me nā pepa lōʻihi o ka anode a me ka cathode, hoʻokaʻawale 'ia e ka uku-insulating mea, olokaa a paa i loko o ka cylinders e malama i wahi a me ka nui ikehu e like me ka hiki. ʻO kēia cathode (negatively charged) Anode (positively charged) nā ʻaoʻao no ka hoʻohui ʻana i nā uku like ma waena o nā pūnaewele, e loaʻa ana i kahi pākaukau ikaika - hoʻohui lākou i hoʻokahi, inā makemake ʻoe.
E like me ka capacitor, hoʻonui ia i kona capacitance ma ka hōʻemi ʻana i ka spacing ma waena o ka anode a me nā pepa cathode, e hoʻololi ana i ka dielectric (ka mea insulating ma luna ma waena o nā ʻāpana) i kahi me ka ʻae ʻoi aku ka kiʻekiʻe, a me ka hoʻonui ʻana i ka wahi o ka anode a me ka cathode. ʻO ka hana hou aʻe i ka (mana) Tesla EV pākaukau ʻo ka 2170, nona ka cylinder ʻoi aʻe ma mua o ka 18650, ʻo 21mm x 70mm ke ana a me ke kaumaha ma kahi o 68 grams. volts a me ka hoʻokuʻu ʻana ma lalo o 2.5 volts, e mālama ana i ka 4800 mAh i kēlā me kēia kelepona.
Aia kekahi kālepa-off, akā naʻe, ʻo ia ka hapa nui e pili ana i ke kū'ē a me ka wela me ka pono o kahi pahu nui iki. I ka hihia o ka 2170, ʻo ka hoʻonui ʻana i ka nui o ka anode / cathode plate ka hopena i kahi ala hoʻopiʻi lōʻihi, ʻo ia hoʻi ka ʻoi aku o ke kū'ē, no laila ʻoi aku. e pakele ana ka ikehu mai ka pākaukau e like me ka wela a me ka hoʻopilikia ʻana i ke koi hoʻouka wikiwiki.
No ka hana ʻana i kahi pākaukau o ka hanauna e hiki mai ana me ka mana hou aku (akā me ka hoʻonui ʻole ʻana i ke kūʻē), ua hoʻolālā nā mea ʻenehana Tesla i kahi pākaukau ʻoi aku ka nui me kahi hoʻolālā i kapa ʻia ʻo "papa" e hoʻopōkole i ke ala uila a no laila e hōʻemi i ka nui o ka wela i hana ʻia e ke kū'ē. Hiki ke hāʻawi ʻia ka hapa nui o kēia i ka mea ʻoi aku ka maikaʻi o nā mea noiʻi pākaukau ma ka honua.
Hoʻolālā ʻia ka pākaukau 4680 i kahi ʻano helix tiled no ka hana maʻalahi, me ka nui o ka pūʻolo o 46mm ke anawaena a me 80mm ka lōʻihi. ʻAʻole i loaʻa ke kaumaha, akā ua hōʻike ʻia nā hiʻohiʻona uila ʻē aʻe e like a like paha;akā naʻe, ua helu ʻia kēlā me kēia kelepona ma kahi o 9000 mAh, ʻo ia ka mea e maikaʻi ai nā pā pāpaʻi pāpaʻi Tesla hou. Eia kekahi, ʻoi aku ka maikaʻi o kona wikiwiki ʻana no ka koi wikiwiki.
ʻOiai ʻo ka hoʻonui ʻana i ka nui o kēlā me kēia cell ma mua o ka emi ʻana paha e kūʻē paha i nā koi hoʻolālā o ka pākaukau, ʻo ka hoʻomaikaʻi ʻana i ka mana mana a me ka mana wela o ka 4680 i hoʻohālikelike ʻia i ka 18650 a me 2170 ka hopena i ka liʻiliʻi liʻiliʻi i hoʻohālikelike ʻia i ka hoʻohana ʻana i ka Battery 18650 a me 2170 -ʻoi aku ka mana o nā hiʻohiʻona Tesla ma mua i kēlā me kēia pākaukau o ka nui like.
Mai kahi hiʻohiʻona helu, ʻo ia ka mea e koi ʻia ma kahi o 960 "4680" mau kelepona e hoʻopiha i ka wahi like me 4,416 "2170", akā me nā pōmaikaʻi ʻē aʻe e like me nā kumukūʻai haʻahaʻa haʻahaʻa no kWh a me ka hoʻohana ʻana i ka 4680 Hoʻonui nui ʻia ka mana.
E like me ka mea i ʻōlelo ʻia, manaʻo ʻia ka 4680 e hāʻawi i 5 mau manawa o ka mālama ʻana i ka ikehu a me 6 mau manawa i ka mana i hoʻohālikelike ʻia i ka pākaukau 2170, ʻo ia ka unuhi ʻana i kahi hoʻonui hoʻokele i manaʻo ʻia mai 82 kWh a i 95 kWh i nā Teslas Mileage hou e piʻi a hiki i 16%.
E hoʻomanaʻo, ʻo kēia wale nō nā kumu kumu o nā ʻenehana Tesla, ʻoi aku ka nui ma hope o ka ʻenehana. ka hana ʻana i ka wela, ka nalowale o ka mana, a… ʻoiaʻiʻo nō… ka pilikia o ke ahi pākaukau EV.
Inā makemake ʻoe i nā All-Things-Tesla, eia kou manawa e kūʻai ai i kahi mana Hot Wheels RC o ka Tesla Cybertruck.
ʻO Timothy Boyer he mea hoʻolaha Tesla a me EV no Torque News ma Cincinnati. Ua ʻike ʻo ia i ka hoʻihoʻi hou ʻana o ke kaʻa, hoʻihoʻi mau ʻo ia i nā kaʻa kahiko a hoʻololi i nā mīkini e hoʻomaikaʻi i ka hana.
