ʻAoʻao hydrogen hou no BMW
Nā mea
Ke hoʻomākaukau nei ka ʻoihana Bavarian i kahi moʻo X5 me nā aila wahie
ʻO BMW paha ka ʻoihana holo lōʻihi loa ma ka hoʻokele waiwai hydrogen. Ke hoʻomohala nei ka ʻoihana i nā ʻenekini hoʻāhu hydrogen no nā makahiki he nui. I kēia manawa ke holo nei kekahi manaʻo ʻē aʻe.
Kū paha ka neʻe uila, akā he nuances ponoʻī kona. Inā ʻaʻole, ʻoiaʻiʻo, kuhi mākou i nā kaʻa o ke kinoea hydrogen i loko o kēia hui. Hoʻomaopopo kēia i ke ʻano o ke kele i nīnau ʻia e hana i ka uila ma muli o ka hui pū ʻana o ka hydrogen a me ka oxygen i loko o kahi mea hana kemika, a hoʻohana ʻia ia e hana i ka kaʻa uila e hoʻokele i ke kaʻa. Loaʻa i ka Volkswagen Group kahi hoʻolālā paʻa no ka hoʻomohala ʻana i kēia ʻano ʻenehana a hāʻawi ʻia i ka hoʻomohala ʻana i nā ʻenekini Audi.
ʻO Toyota, ka mea e hoʻomākaukau nei i kahi Mirai hou, a ʻo Hyundai a me Honda, ke hana nui nei hoʻi i kēia hana. Ma loko o ka hui PSA, kuleana ʻo Opel no ka hoʻomohala ʻana i nā ʻenehana hydrogen cell, i loaʻa he mau makahiki he nui i ka ʻike ma kēia kahua ma ke ʻano he ʻenehana no General Motors.
ʻAʻole paha e ʻike pinepine ʻia ia mau kaʻa ma nā ala o ʻEulopa, akā hiki ke wānana ʻia ka wā e ʻike ʻia ana he hiki ke kūkulu i nā mahiʻai makani kūloko e hana i ka uila a me ka hydrogen mai ka wai e ka hāʻawi ʻana i nā mea kanu hydrogen. ʻO nā hunaola wahie kahi ʻāpana o ka hoʻohālikelike e ʻae i ka mana i hoʻohuli ʻia e hoʻohua i ka uila mai nā kumuwaiwai hou i hydrogen a hoʻi i ka ikehu, ʻo ia hoʻi, no ka mālama ʻana.
Ma o ka hui pū ʻana me Toyota, hiki nō iā BMW ke hilinaʻi i ka hele ʻana ma kēia mākeke niche liʻiliʻi. Hoʻokahi makahiki a me ka hapa ma hope o ka hōʻike ʻana o ka BMW I-Hydrogen Next ma Frankfurt, ua hāʻawi ʻo BMW i nā kikoʻī hou aʻe e pili ana i ke kaʻa e pili ana i ka hana hana - ʻo kēia manawa e pili ana i ka X5 o kēia manawa. No nā makahiki, ua hōʻike ʻo BMW i nā prototypes kaʻa hydrogen e hoʻohana ana i ka hydrogen i wahie no nā ʻenekini hoʻopau i loko. ʻO ka hydrogen cell ka hopena maikaʻi loa e pili ana i ka pono, akā ua loaʻa i nā mea ʻenekini BMW ka ʻike kūpono i ke kahua o nā kaʻina puhi ahi no nā wahie i loaʻa ʻole ke kalapona i kā lākou mau mole. Eia naʻe, he kumuhana ʻokoʻa kēia.
ʻAʻole like me ka hoa Toyota, e hoʻomaka koke ana i ka lua o ka hanauna Mirai e pili ana i ka ʻōnaehana modular TNGA, ʻoi aku ka makaʻala o BMW ma kēia wahi. No laila, hōʻike ʻia ka I-NEXT hou ma ke ʻano he kaʻa hana, akā ma ke ʻano he kaʻa kaʻa liʻiliʻi e hōʻike ʻia i kahi liʻiliʻi o nā mea kūʻai aku i koho ʻia. ʻO ka wehewehe ʻana no kēia mea aia i loko o ka ʻoihana liʻiliʻi. "I ko mākou manaʻo, ma ke ʻano he kumu ikehu, pono e hoʻomaka ka hydrogen e hana ʻia i ka nui a me ke kōkua o ka ikehu ʻōmaʻomaʻo, a loaʻa pū i nā kumukūʻai hoʻokūkū. E hoʻohana ʻia nā ʻenekini wahie i nā kaʻa paʻakikī i ka uila i kēia manawa, e like me nā kaʻa kaumaha, "wahi a Klaus Fröhlich, lālā o ka papa alakaʻi o BMW AG a me ke kuleana no ka noiʻi a me ka hoʻomohala ʻana.
O na pu ki a me ka wahie aeea i symbiosis
Eia naʻe, kūpaʻa ʻo BMW i kahi hoʻolālā hydrogen maʻemaʻe no ka wā lōʻihi. ʻO kēia kahi ʻāpana o ka hoʻolālā holoʻokoʻa o ka hui e hoʻomohala i nā ʻano mana like ʻole, ʻaʻole wale no nā kaʻa uila. "Ke manaʻoʻiʻo nei mākou i ka wā e hiki mai ana e loaʻa nā ʻano o ka neʻe ʻana, no ka mea ʻaʻohe hopena hoʻokahi e hoʻokō i nā koi āpau o ka neʻe ʻana o ka mea kūʻai aku. Ke manaʻoʻiʻo nei mākou e lilo ka hydrogen ma ke ʻano he wahie ke kia ʻehā i kā mākou kōpili powertrain i ka wā lōʻihi," wahi a Fröhlich.
Ma I-Hydrogen Aʻe, hoʻohana ʻo BMW i nā ʻōnaehana ʻenehana i hana ʻia me ka laulima me ka Toyota alakaʻi alakaʻi ʻoihana. ʻO nā hui ʻelua he mau hoa hana ma kēia wahi mai ka 2013. Ma lalo o ka uhi mua o X5 kahi ahu o nā hunaola wahie e hoʻoulu ai i ka uila ma o ka hana ʻana ma waena o hydrogen a me oxygen (mai ka lewa). ʻO ka mana hana nui i hiki ke hāʻawi ʻia i ka mea he 125 kW. ʻO ka ʻāpana pūnaewele wahie kahi hoʻomohala ʻoihana Bavarian, like me kāna hana pākahi ponoʻī (me nā lithium-ion cell mai nā mea hoʻolako e like me Samsung SDI), a ua kūkulu pū ʻia nā pūnaewele me Toyota.
Mālama ʻia ka hydrogen i loko o ʻelua pahu kiʻekiʻena kiʻekiʻe (700 bar). He ʻehā mau minuke ke kaʻina hana hoʻoilina, a he keu kūpono ia ma mua o nā kaʻa uila. Hoʻohana ka ʻōnaehana i kahi puʻupuʻu lithium-ion ma ke ʻano he buffer element, e hāʻawi ana i ka hoʻihoʻi ʻelua i ka wā o ka paleki a me ke kaulike o ka ikehu a, no laila, kōkua i ka holomua I kēiaʻano, ʻano like ka ʻōnaehana me kahi kaʻa hybrid. Pono kēia mau mea āpau no ka mea ma ka hoʻomaʻamaʻa ʻoi aku ka nui o ka mana o ka pila ma mua o kahi pūnaewele wahie, ʻo ia hoʻi, inā hiki i ka mea hope ke hoʻoili iā ia i ka ukana piha, i ka wā o ka hoʻouka kiʻekiʻe hiki i ka pila ke hāʻawi i nā huahana kiʻekiʻe a me ka mana ʻōnaehana o 374. hp. ʻO ka hoʻokele uila ponoʻī ka hanauna BMW hou ʻelima a e hoʻomaka i ka BMW iX3.
I ka 2015, ua wehe ʻo BMW i kahi prototype hydrogen car i hoʻokumu ʻia ma BMW 5 GT, akā i ka hoʻomaʻamaʻa ʻana, e wehe ʻo I-Hydrogen Next i kahi ʻaoʻao hydrogen hou no ka brand. E hoʻomaka ia me kahi moʻo liʻiliʻi i 2022, me nā pūʻulu ʻoi aku ka nui i manaʻo ʻia i ka hapa lua o ke anahulu.
