Nā palena pākaukau
1.1 Ike uila
He kilowatt-hour (kWh) ka ʻāpana o ka ikehu pākahiko, i kapa ʻia ʻo "degree". ʻO 1kWh ka manaʻo "ka ikehu i hoʻopau ʻia e kahi mea uila me ka mana o 1 kilowatt no hoʻokahi hola." No ka maʻalahi o ka hoʻomaopopo ʻana, hoʻohana nui kēia moʻolelo lehulehu i ka "degree" e hōʻike ai. Pono ka poʻe heluhelu e ʻike he ʻāpana ia o ka ikehu uila a ʻaʻole pono e ʻimi i kona manaʻo.
[Laʻana] ʻO ka mana pākaukau o nā kaʻa a me nā SUV me kahi ākea o 500km ma kahi o 60 degere a me 70 degere. I kēia manawa, hiki ke hoʻolako ʻia nā kaʻa uila maʻemaʻe i hana ʻia me nā pihi me ka mana kiʻekiʻe o 150 kwh a me kahi pae hoʻokele theoretical a hiki i 1,000km.
Aia kekahi papa inoa me ka ʻike kaʻa ma ka puka mua ʻākau (a i ʻole ka puka hope ʻākau) o kahi kaʻa ikehu hou. Ua helu ʻia ke degere o ka pākaukau ma ka hoʻohana ʻana i ka volta helu helu ʻia × kaha helu helu/1000. He ʻokoʻa iki paha ka hopena i helu ʻia mai ka waiwai kūhelu o ka hui kaʻa.
1.2 SOC
ʻO SOC ka pōkole o "Mokuaina o ka uku", e pili ana i ke kūlana o ka pila, ʻo ia hoʻi, ke koena o ka mana pākaukau, i hōʻike pinepine ʻia ma ke ʻano he pākēneka.
1.3 ʻAno pākaukau
ʻO ka hapa nui o nā kaʻa ikehu hou ma ka mākeke e hoʻohana i nā pākahi lithium-ion, hiki ke hoʻokaʻawale ʻia i nā pā lithium iron phosphate a me nā pākahi lithium ternary.
I waena o lākou, aia ʻelua mau hōʻike kikoʻī o ka "kūpono maikaʻi ʻole" o nā pā lithium hao phosphate. ʻO ka mea mua, ʻaʻole pololei ka hōʻike SOC: no ka laʻana, ua ʻike ka mea kākau i ka Xpeng P5, i lawe i 50 mau minuke e hoʻopiʻi mai 20% a i 99%, ʻoiai e hoʻopiʻi ana mai 99% a Ua lawe ʻo ia i 30 mau minuke a hiki i 100%, ʻo ia ka mea maopopo. pilikia me ka hōʻike SOC; ʻO ka lua, ʻaʻole kūlike ka wikiwiki o ka mana (ʻo ia hoʻi ka mea nui i ka wā i hoʻopiha piha ʻia): ʻaʻole hōʻike kekahi mau kaʻa i ka loli ʻana o ke ola pākaukau ma hope o ke kaʻa ʻana i 10km ma hope o ka hoʻopiha piha ʻana, ʻoiai ʻaʻole ʻike kekahi mau kaʻa. Ua hāʻule ke ola pākaukau i 5km ma hope o kekahi mau ʻanuʻu. No laila, pono e hoʻopiha piha ʻia nā pākahi lithium iron phosphate i hoʻokahi manawa i ka pule e hoʻoponopono i ka paʻa ʻana o nā cell.
ʻO ka mea ʻē aʻe, ma muli o ke ʻano o ka mea, ʻaʻole kūpono nā pā lithium ternary no ka kaʻa ma hope o ka hoʻopiha piha ʻana (akā hiki iā lākou ke hoʻomau i ke kaʻa ʻana ma lalo o 90% koke ma hope o ka hoʻopiha piha ʻana).Eia kekahi, ʻaʻole pono e hoʻokele ʻia ma lalo o ke ʻano haʻahaʻa haʻahaʻa (SOC <20%), ʻaʻole hoʻi e hoʻouka ʻia ma nā wahi ʻoi loa (nā wela ma luna o 30 ° C a ma lalo o 0 ° C).
E like me ka wikiwiki o ka hoʻouka ʻana, hiki ke hoʻokaʻawale ʻia nā ʻano hana i ka hoʻopiʻi wikiwiki a me ka hoʻopiʻi lohi.
ʻO ka volta charging o ka hoʻouka wikiwiki ʻana ʻo ia ka volta hana o nā kaʻa uila (ma kahi o 360-400V). I ka mana kiʻekiʻe, hiki i kēia manawa ke hiki i 200-250A, e like me 70-100kW o ka mana. ʻO kekahi mau hiʻohiʻona me ka hoʻopiʻi ʻana e like me kā lākou kūʻai aku hiki ke hiki i 150kW ma o ka volta kiʻekiʻe. maluna. Hiki i ka hapa nui o nā kaʻa ke uku mai 30% a 80% i ka hapalua hola.
[Laʻana] ʻO ka lawe ʻana i kahi kaʻa me ka nui o ka pākaukau o 60 degere (me kahi ākea o 500km) ma ke ʻano he laʻana, hiki ke hoʻopiʻi wikiwiki (mana 60kW)hoʻouka i kahi pākaukauke ola o 250km i ka hapalua hola (ka mana kiʻekiʻe)
Inā makemake ʻoe e ʻike hou aku e pili ana i kēia, e ʻoluʻolu e kelepona mai iā mākou.
