Hoʻokomo ʻia nā pākahi hou ma ka International Space Station: Li-ion, 357 kWh. Hele ʻo NiMH kahiko i ka Honua
Ua wehe ʻia a hoʻokuʻu ʻia mai ka International Space Station (ISS) ka 2,9 tonne nickel metal hydride pack battery pack. Manaʻo ʻia lākou e kaʻapuni i ka Honua no ʻelua a ʻehā mau makahiki a laila e wela i ka lewa. 48 modules me nickel-metal hydride cell i pani ʻia me 24 modules me ka lithium-ion cell.
ISS Battery: LiCoO2, 357 kWh, a hiki i 60 mau kaʻina hana
Ua hoʻohana ʻia nā pihi NiMH ma ka ISS no ka mālama ʻana i ka ikehu i hana ʻia e nā pūnaewele photovoltaic. ʻO ka mea kahiko i lawelawe ʻia mai 2006, no laila ua hoʻoholo ʻo NASA e hoʻololi ʻia ke hiki i kona ola pono. Ua hoʻoholo ʻia e hoʻokumu ʻia nā pihi hou i nā cell lithium-ion, kahi e hāʻawi ai i ka nui o ka ikehu kiʻekiʻe ma kēlā me kēia ʻāpana o ka nui a me ka leo.
Ua manaʻo ʻia kēlā Pono nā mea hou e kū i 10 mau makahiki a me 60 mau manawa hanaa ma ka hopena o ke ola e hāʻawi i ka liʻiliʻi o 48 Ah ma kahi o ka 134 Ah (0,5 kWh) kumu. E like me kāu e ʻike ai, ʻae ʻo NASA me ka hoʻohaʻahaʻa nui aʻe ma mua o nā mea hana EV no ka mea he 36 pakeneka wale nō o ka mana kumu i manaʻo ʻia he hopena o ke ola. I nā kaʻa uila, ua hoʻonohonoho pinepine ʻia ka paepae pani ma kahi o 65-70 pakeneka o ka nui o ka pākaukau hale hana.
I ka pōʻai hoʻāʻo, ua hoʻoholo ʻia e kūkulu ʻia nā pā (ʻoi aku ka pololei: ORU modules) ma ke kumu o nā cell. Kumu Yuasa me nā cathodes i hana ʻia me ka lithium-cobalt oxide (LiCoO2). ʻO kēlā me kēia o lākou he 30 mau pūnaewele, no laila he mana o 14,87 kWh hoʻokahi module, piha piha o na pila no ka malama ana i 357 kWh o ka ikehu. E like me nā pūnaewele LiCoO2 hiki ke pahū inā pōʻino, ua hoʻokō ʻia kekahi mau hoʻāʻo, me kā lākou hana i ka wā e hou ana a hoʻouka hou.
Ua hoʻomaka ka mikiona hoʻololi pākahi i ka makahiki 2016 a ua pau i ka Pōʻalima 11 Malaki. Ua hoʻokuʻu ʻia kahi pallet me 48 NiMH-based batteries i ka Honua - ma ke kiʻi ʻike ʻia lākou ma 427 mau kilomita ma luna o Chile.... Ma hope o ka hoʻokuʻu ʻana, neʻe ʻo ia i ka wikiwiki o 7,7 km / s i kahi orbit haʻahaʻa haʻahaʻa. Manaʻo ʻo NASA i loko o ʻelua a ʻehā mau makahiki e komo ka ukana i ka lewa a wela i loko "Me ka poino ole." Ke noʻonoʻo nei i ke kaumaha o ke kit (2,9 tons) a me kona ʻano (module interconnected), pono mākou e manaʻo i kahi kaʻa ʻālohilohi e hāʻule i loko o ka ua o ka ʻōpala.
Manaʻolana, no ka mea, ʻo 2,9 tons ke kaumaha o kahi SUV nui loa. A ʻo ka "ʻōpala" nui loa i hoʻokuʻu ʻia mai ka International Space Station ...
