ʻO nā ʻakika ʻakika alakaʻi

ʻAkika-ʻakika

ʻO kapākahi-ʻakikaʻO ia ke ʻano o ka pākaukau rechargeable i hana mua ʻia i ka makahiki 1859 e ke kauka lapaʻau Farani ʻo Gaston Planté.ʻO ia ka muaʻano ʻanoo ka pākaukau hiki ke hoʻouka hou ʻiahana ʻia.Ke hoʻohālikelike ʻia me nā ʻaʻa pākahi rechargeable hou, ʻoi aku ka haʻahaʻa o ka ikehu haʻahaʻa o nā pākī lead-acid.ʻOiai ʻo kēia, ʻo ko lākou hiki ke hoʻolako i nā ʻauheʻe kiʻekiʻe, ʻo ia hoʻi, ʻoi aku ka nui o ka mana-a-kaumaha o nā cell.ʻO kēia mau hiʻohiʻona, me kā lākou kumu kūʻai haʻahaʻa, hoʻohiwahiwa iā lākou no ka hoʻohana ʻana i nā kaʻa kaʻa e hāʻawi i ke ʻano kiʻekiʻe e koi ʻia e nā kaʻa hoʻomaka.Loaʻa i nā ʻakika Lead-acid ke ola pōkole pōkole (maʻa mau ma lalo o 500 mau pōʻai hohonu) a me ke ola holoʻokoʻa (ma muli o ka "sulphation pālua" i ka moku i hoʻokuʻu ʻia).

Kele-keleamoena aniani-moenaHe mea maʻamau nā pā i kēia mau kuleana, i ʻike pū ʻia ʻo VRLA (valve-regulated lead-acid).

I ka mokuʻāina i hoʻopiʻi ʻia, mālama ʻia ka ikehu kemika o ka pākaukau ma ka ʻokoʻa kūpono ma waena o ke kēpau metala ma ka ʻaoʻao ʻino a me ka PbO.₂ma ka aoao maikai.Loaʻa iā ia ka ʻaoʻao maikaʻi PbO2 a me ke alakaʻi metala negtive, papa insulation, pahu plastic, sulfuric acid a me ka wai.

Ke hoʻokuʻu ʻia, ka hopena electrode maikaʻi:bO2 + 4H+ + SO42- + 2e- = PbSO4 + 2H2O

Pane ʻino: Pb + SO42- - 2e- = PbSO4

Ka hopena holoʻokoʻa: PbO2 + Pb + 2H2SO4 === 2PbSO4 + 2H2O (Ke hoʻokuʻu ʻia ka pane ʻākau, ke hoʻopiʻi nei ka pane hema).

Hoʻohana ʻia nā ʻeke ʻakika lead-acid (WLABs) i nā ʻakika lead-acid e pono e hoʻopau ʻia. 

Ma waena o nā hoʻohana ʻokoʻa o WLAB, ʻo ka noi nui i loko o nā kaʻa, ʻoiai ʻo ka noi ʻana ma ka UPS uninterruptible power supply kahi ʻano e ulu nei ma muli o ka ulu ʻana o nā ʻāpana kelepona a me ka ʻike ʻike (ʻoi aku ka ʻike kikowaena).Me ka hoʻonui nui ʻana o nā kikowaena data, manaʻo ʻia e hoʻonui mau ʻia nā WLAB e kū mai ana mai kēia ʻāpana i nā makahiki e hiki mai ana.

Hiki iā mākou ke hāʻawi i kahilaina hoʻihoʻi hou ʻana i nā ʻakika waikona kepau, me ka ʻōnaehana wāwahi a me ka hoʻokaʻawale ʻana, ʻōnaehana umu, ʻōnaehana hoʻomaʻemaʻe, a me ka ʻōnaehana kānana huelo, etc.

ʻIke hou aku, e ʻoluʻolu e kelepona mai iā mākou.

Me ke aloha,
