I Nowemapa 2022, ua hoʻomau ka piʻi ʻana o ke kūʻai aku ʻana o nā kaʻa uila honua ma ka helu pālua makahiki-ma-makahiki (46%), me ke kūʻai aku ʻana o nā kaʻa uila no 18% o ka mākeke kaʻa honua holoʻokoʻa, me ka ulu ʻana o ka māhele mākeke o nā kaʻa uila maʻemaʻe i 13%.
ʻAʻohe kānalua ua lilo ka hoʻokele uila i ke ala hoʻomohala o ka ʻoihana kaʻa honua. I ke au honua o ka ulu nui ʻana o nā kaʻa ikehu hou, ua hoʻolauna pū nā mea i hui pū ʻia no nā pahu pila kaʻa uila i nā manawa kūpono nui no ka hoʻomohala ʻana, a ua hoʻokau pū nā ʻoihana kaʻa nui i nā koi kiʻekiʻe no ka ʻenehana a me ka hana o nā mea i hui pū ʻia no nā pahu pila kaʻa uila.

Pono nā keʻena no nā ʻōnaehana pila kaʻa uila kiʻekiʻe e kaulike i kekahi mau koi paʻakikī. ʻO ka mea mua, pono lākou e hāʻawi i nā waiwai mechanical lōʻihi, me ka torsional a me ka flexural stiffness, e hāpai i nā cell kaumaha ma ke ola o ka ʻeke me ka pale ʻana iā lākou mai ka pala, ka hopena pōhaku, ka lepo a me ka makū, a me ka electrolyte leakage. I kekahi mau hihia, pono nō hoʻi ka hihia pila e hiki ke pale aku i ka hoʻokuʻu electrostatic a me EMI/RFI mai nā ʻōnaehana kokoke.
ʻO ka lua, inā he ulia, pono ka hihia e pale i ka ʻōnaehana pila mai ka haki ʻana, ka puka ʻana, a i ʻole ka pōkole ʻana ma muli o ke komo ʻana o ka wai/makū. ʻO ke kolu, pono ka ʻōnaehana pila EV e kōkua i ka mālama ʻana i kēlā me kēia cell i loko o ka pae hana wela i makemake ʻia i ka wā e hoʻouka ai/hoʻokuʻu ʻana i nā ʻano ʻano like ʻole. Inā he ahi, pono lākou e mālama i ka ʻeke pila mai ka pili ʻana me nā lapalapa no ka lōʻihi e hiki ai, me ka pale ʻana i nā mea noho kaʻa mai ka wela a me nā lapalapa i hana ʻia e ka holo wela i loko o ka ʻeke pila. Aia kekahi mau pilikia e like me ka hopena o ke kaumaha ma ka pae hoʻokele, ka hopena o nā hoʻomanawanui stacking cell ma ka wahi hoʻonohonoho, nā kumukūʻai hana, ka mālama ʻana a me ka hana hou ʻana i ka hopena o ke ola.
