ʻO ke ʻano nui o nā ʻenekini hāmeʻa mana ma ka mākeke he mea paʻakikī, akā ʻoi aku ka maʻalahi ma mua o ka mea i ʻike ʻia. Hiki iā lākou ke hoʻohui ʻia i hoʻokahi o ʻekolu mau ʻano nui, a ʻo kēlā me kēia mea hana hana mana cordless wale nō e hana i nā pā a me nā loina no kā lākou huahana, ʻo ia hoʻi, ua kaupalena ʻia ʻoe i kāu hāmeʻa.
Hoʻohana like nā ʻano ʻokoʻa ʻekolu o nā ʻano pākahi (e nānā. Pehea ka hana ʻana o ka pā uila uila ʻole?), akā he ʻokoʻa ka "chemistry". ʻO kēia nā nickel-cadmium (NiCd), nickel-metal hydride (NiMH) a me ka lithium-ion (Li-ion).
ʻO ka uila uila a me ka hiki ke ʻokoʻa nui ma waena o nā pila. Kūkākūkā ʻia kēia mau mea ma ka ʻaoʻao He aha ka nui a me ke kaumaha o nā ʻeke hāmeʻa cordless i loaʻa?
Nickel cadmium
He lōʻihi loa nā pākiki Nickel Cadmium (NiCd) a he kūpono inā pono ʻoe e hoʻohana i nā ʻeke no ka hana maʻamau a me ka ikaika i kēlā me kēia lā. Ua pane maikaʻi lākou i ka hoʻopiʻi ʻana i nā manawa he nui a laila hoʻohana ʻia. ʻO ka waiho ʻana iā lākou i loko o nā loina a me ka hoʻohana ʻana iā lākou i kekahi manawa e hōʻemi i ko lākou ola.
Hiki iā lākou ke hoʻopaʻi ʻia ma luna o 1,000 mau manawa ma mua o ka hoʻomaka ʻana o kā lākou pae hana e hoʻomāhuahua.
Hiki iā lākou ke hoʻouka hou ʻia a hoʻohana ʻia ma nā haʻahaʻa haʻahaʻa ma mua o nā kemika ʻē aʻe, me ka liʻiliʻi o ka hopena maikaʻi ʻole i ka pā.
Hoʻokuʻu pono ʻia nā ʻaʻa NiCd (e emi mālie ka uku inā ʻaʻole i hoʻohana ʻia) i ka wā e waiho ai, akā ʻaʻole e like me ka wikiwiki e like me nā pihi NiMH.
ʻO nā ʻano ʻekolu, ʻo nā pā NiCd ka haʻahaʻa haʻahaʻa o ka ikehu, ʻo ia ka mea e hāʻawi i ka mana like me ka NiMH a i ʻole ka lithium-ion pākahi, pono lākou e ʻoi aku ka nui a me ke kaumaha.
Pono lākou e hoʻokuʻu ʻia a laila hoʻopaʻa mau ʻia e pale i ka "hopena hoʻomanaʻo" (e nānā Pehea e hoʻopaʻa ai i kahi pākahi nickel no nā mea hana mana), ka mea e hooki ai i ka hana ana o ka pila.
He pilikia nō hoʻi ka hoʻolei ʻia ʻana o nā pākahi nickel-cadmium no ka mea aia nā mea ʻawaʻawa e pōʻino i ke kaiapuni. ʻO ka koho maikaʻi loa e hana hou iā lākou.
hydride metala nikela
ʻO ka pōmaikaʻi nui loa o nā pākaukau nickel metal hydride (NiMH) rechargeable ma luna o NiCd ʻo ia ka hāʻawi ʻana i ka 40% kiʻekiʻe o ka ikehu. ʻO ia ke ʻano hiki ke liʻiliʻi a ʻoi aku ka māmā akā hāʻawi mau i ka nui o ka mana. Akā naʻe, ʻaʻole like lākou i ka lōʻihi.
Hoʻohana maikaʻi ʻia lākou no nā hana maʻalahi, no ka mea, hiki i nā wela kiʻekiʻe a me ka hoʻohana koʻikoʻi ke hōʻemi i ke ola pākaukau mai ka 300-500 charge/discharge cycles i 200-300.
ʻOiai pono e hoʻokuʻu piha ʻia nā pākahi nickel-metal hydride i kēlā me kēia manawa, ʻaʻole hiki ke maʻalahi i ka hopena hoʻomanaʻo e like me nā pihi nickel-cadmium.
Loaʻa i nā pila NiMH nā mea ʻawaʻawa maʻalahi, no laila ʻoi aku ka maikaʻi no ke kaiapuni.
Pono lākou i ka manawa lōʻihi o ka hoʻouka ʻana ma mua o NiCd no ka mea ua wela lākou, hiki ke hōʻino iā lākou. Loaʻa iā lākou kahi helu hoʻokuʻu ponoʻī ʻo 50% kiʻekiʻe ma mua o nā pihi NiCd.
ʻOi aku ka maikaʻi o nā pila NiMH ma kahi o 20% ma mua o nā pihi NiCd, akā manaʻo pinepine ʻia he kūpono no ka nui o ka ikehu.
lithium ion
ʻO ka Lithium he metala māmā e hana maʻalahi i nā ion (e nānā. Pehea ka hana ʻana o ka pā uila uila ʻole?), no laila, kūpono no ka hana ʻana i nā pā.
ʻO nā ʻaniani Lithium-ion (Li-ion) i hoʻopaʻa hou ʻia, ʻo ia nā pihi pipiʻi loa no nā mea hana mana cordless, akā liʻiliʻi loa lākou a māmā a ʻelua ʻoi aku ka nui o ka ikehu o nā pihi nickel-cadmium.
Eia kekahi, ʻaʻole lākou e koi i ka mālama kūikawā no ka mea ʻaʻole lākou e pili i ka hopena hoʻomanaʻo.
ʻOiai lākou e hoʻokuʻu iā lākou iho, ʻo ka hapa ka hapa o nā pā nickel-cadmium. Hiki ke mālama ʻia kekahi mau pākahi lithium-ion no 500 mau lā me ka ʻole e hoʻopiha hou ʻia i ka manawa aʻe e hoʻohana ʻia ai.
Ma ka ʻaoʻao haʻahaʻa, he palupalu lākou a koi i kahi kaapuni pale e nānā i ka volta a me ka mahana e pale ai i ka pōʻino o ka pā. Hiki wawe ko lakou mau makahiki; e emi ana ka hana ma hope o hoʻokahi makahiki.
