Ua hoʻomohala ʻo Mahle, kahi hui ʻāpana kaʻa Kelemania, i nā kaʻa uila kiʻekiʻe no nā EV, a ʻaʻole i manaʻo ʻia e hoʻoikaika ʻia ka hoʻolako ʻana a me ke koi ʻana i nā honua laha.
ʻAʻole like me nā ʻenekini hoʻopau i loko, ʻo ke ʻano kumu a me ke kumu hana o nā kaʻa uila he mea maʻalahi loa.Manaʻo wau he nui ka poʻe i pāʻani me ka "kaʻa huila ʻehā" i ko lākou wā ʻōpio.Aia kekahi kaʻa uila i loko.
ʻO ke kumu hana o ke kaʻa ʻo ia ka hana ʻana o ke kahua magnetic i ka ikaika o ke au e hoʻohuli ai i ka motika.ʻO ke kaʻa kaʻa he mea hana e hoʻololi i ka ikehu uila i ikehu mechanical.Hoʻohana ʻo ia i kahi wili ikaika e hoʻohua ai i kahi māla magnetic rotating a hana i ka rotor e hana i kahi torque rotation ikaika magnetoelectric.Maʻalahi ka hoʻohana ʻana i ka mīkini, hilinaʻi i ka hana, haʻahaʻa i ke kumu kūʻai a paʻa i ke ʻano.
Nui nā mea i loko o ko mākou ola e hiki ke hoʻololi, e like me nā mea maloʻo lauoho, nā mea hoʻomaʻemaʻe, a me nā mea ʻē aʻe.
ʻO ke kaʻa i loko o kahi kaʻa uila maʻemaʻe ʻoi aku ka nui a ʻoi aku ka paʻakikī, akā ʻo ke kumu kumu like.
ʻO ka mea e pono ai e hoʻoili i ka ikaika i loko o ke kaʻa, a ʻo ka mea e hoʻokele ai i ka uila mai ka pākaukau ʻo ia ka coil coil i loko o ka moto.ʻO ka mea nāna i hoʻokumu i ke kahua magnetic he magnet.ʻO ia hoʻi nā mea kumu ʻelua e hana ai i kahi kaʻa.
I ka wā ma mua, ʻo nā magnets i hoʻohana ʻia i nā kaʻa uila he mau magnet mau loa i hana ʻia i ka hao, akā ʻo ka pilikia ʻo ia ka palena o ka ikaika o ka māla magnetic.No laila inā e hoʻemi ʻoe i ka mīkini i ka nui i hoʻopili ʻia i loko o kahi kelepona i kēia lā, ʻaʻole e loaʻa iā ʻoe ka ikaika magnetic āu e pono ai.
Eia nō naʻe, i ka makahiki 1980, ua ʻike ʻia kahi ʻano magnet mau loa, i kapa ʻia ʻo "neodymium magnet".ʻO nā mākēneki Neodymium he ʻelua ʻoi aku ka ikaika ma mua o nā magnet maʻamau.ʻO ka hopena, hoʻohana ʻia ia i nā pepeiao pepeiao a me nā poʻo i ʻoi aku ka liʻiliʻi a ʻoi aku ka ikaika ma mua o nā smartphones.Eia kekahi, ʻaʻole paʻakikī ka loaʻa ʻana o "neodymium magnets" i ko mākou ola i kēlā me kēia lā.I kēia manawa, loaʻa i kekahi mau mea haʻiʻōlelo, nā mea kuke induction, a me nā kelepona paʻa i ko mākou ola "neodymium magnets".
ʻO ke kumu e hoʻomaka wikiwiki ai nā EV i kēia lā ma muli o nā "neodymium magnets" hiki ke hoʻomaikaʻi nui i ka nui a i ʻole ka puka ʻana o ka kaʻa.Eia nō naʻe, ma hope o ke komo ʻana i ke kenekulia 21, ua kū mai kahi pilikia hou ma muli o ka hoʻohana ʻana i nā honua laha i nā neodymium magnets.Aia ma Kina ka hapa nui o nā kumuwaiwai honua.Wahi a nā helu helu, ma kahi o 97% o ka honua rare earth magnet raw material e hoʻolako ʻia e Kina.I kēia manawa, ua kapu loa ka lawe ʻana aku i kēia kumuwaiwai.
Ma hope o ka hoʻomohala ʻana i nā magnet neodymium, ua hoʻāʻo ka poʻe ʻepekema i ka hoʻomohala ʻana i nā magnet liʻiliʻi, ikaika, a ʻoi aku ka liʻiliʻi.Ma muli o ka mālama ʻana o Kina i ka hoʻolako ʻana i nā metala laha ʻole a me nā honua laha ʻole, manaʻo kekahi poʻe loiloi ʻaʻole e hāʻule ke kumukūʻai o nā kaʻa uila e like me ka mea i manaʻo ʻia.
Eia naʻe, i kēia mau lā, ua hoʻomohala maikaʻi ka ʻenehana kaʻa kaʻa Kelemania a me nā ʻāpana hoʻomohala ʻo "Mahle" i kahi ʻano kaʻa kaʻa hou ʻaʻole i loaʻa nā mea ʻano honua.ʻAʻole loaʻa nā magnet i ka mīkini i kūkulu ʻia.
Ua ʻike ʻia kēia ala i nā kaʻa he "motor induction" a hana ia i kahi māla magnetic ma ke kahe ʻana i ke au ma kahi stator ma kahi o nā magnet e hiki ai ke kahe.I kēia manawa, ke hoʻopili ʻia ka rotor e ka māla magnetic, e hoʻoulu ia i ka ikehu electromotive, a hui pū nā mea ʻelua e hana i ka ikaika rotational.
ʻO ka waiho wale ʻana, inā hoʻokumu mau ʻia ke kahua magnetic ma ke kāʻei ʻana i ke kaʻa me nā magnet mau loa, a laila ʻo ke ala ke hoʻololi i nā magnet mau me nā electromagnets.He nui nā pono o kēia ʻano, maʻalahi ke kumu o ka hana, a paʻa loa.ʻO ka mea nui loa, ʻaʻole liʻiliʻi ka emi ʻana o ka hana wela, a ʻo kekahi o nā hemahema o nā magnet neodymium ʻo ia ka emi ʻana o kā lākou hana i ka wā e hana ʻia ai ka wela kiʻekiʻe.
Akā, loaʻa nō hoʻi nā hemahema, ʻoiai ke hoʻomau nei ke kahe o kēia manawa ma waena o ka stator a me ka rotor, ua koʻikoʻi ka wela.ʻOiaʻiʻo, hiki ke hoʻohana maikaʻi i ka wela i hana ʻia e ka ʻohi ʻana a hoʻohana ʻia e like me ka mea hoʻomehana i loko o ka kaʻa.Ma waho aʻe o kēlā, aia kekahi mau hemahema.Akā, ua hoʻolaha ʻo MAHLE ua hoʻomohala maikaʻi ʻo ia i kahi kaʻa non-magnetic i hoʻoponopono i nā hemahema o ka mīkini hoʻokomo.
Loaʻa iā MAHLE ʻelua mau pōmaikaʻi nui i kāna kaʻa magnetless hou.ʻAʻole pili kekahi i ka paʻa ʻole o ka hāʻawi ʻana a me ka koi honua.E like me ka mea i ʻōlelo ʻia ma luna, ʻo ka hapa nui o nā metala honua laha ʻole i hoʻohana ʻia i nā magnet mau loa e hoʻolako ʻia nei e Kina, akā ʻaʻole pili nā kaʻa non-magnet e ke kaomi o ka lako honua.Eia kekahi, no ka mea ʻaʻole hoʻohana ʻia nā mea ʻāina laha, hiki ke hāʻawi ʻia ma ke kumu kūʻai haʻahaʻa.
ʻO ka mea ʻē aʻe e hōʻike ana i ka maikaʻi maikaʻi loa, me nā kaʻa i hoʻohana maʻamau ʻia i nā kaʻa uila e loaʻa ana ka pono ma kahi o 70-95%.I nā huaʻōlelo ʻē aʻe, inā hāʻawi ʻoe i 100% o ka mana, hiki iā ʻoe ke hāʻawi i ka 95% o ka hopena.Eia nō naʻe, ma kēia kaʻina hana, ma muli o nā kumu pohō e like me ka poho hao, ʻaʻole hiki ke nalowale i ka hoʻopuka.
Eia naʻe, ʻoi aku ka maikaʻi o Mahler ma mua o 95% i ka nui o nā hihia a hiki i ka 96% i kekahi mau hihia.ʻOiai ʻaʻole i hoʻolaha ʻia nā helu kikoʻī, e manaʻo i ka piʻi iki ʻana o ka laulā i hoʻohālikelike ʻia i ke kumu hoʻohālike mua.
ʻO ka hope, wehewehe ʻo MAHLE ʻaʻole hiki ke hoʻohana wale ʻia ka ʻenekini manuahi i kūkulu ʻia i nā kaʻa uila maʻamau, akā hiki ke hoʻohana ʻia i nā kaʻa kalepa ma o ka amplification.Ua ʻōlelo ʻo MAHLE ua hoʻomaka ʻo ia i ka noiʻi hana nui, a ke manaʻoʻiʻo nei ʻo ia i ka wā e pau ai ka hoʻomohala ʻana o ka kaʻa hou, e hiki iā ia ke hāʻawi i nā motika paʻa, haʻahaʻa a me ka ʻoi aku ka maikaʻi.
Inā pau kēia ʻenehana, hiki paha i ka ʻenehana kaʻa uila holomua o MAHLE ke lilo i wahi hoʻomaka hou no ka ʻenehana kaʻa uila ʻoi aku ka maikaʻi.
