I kēia manawa i ka mākeke, hoʻohana nui nā mea hoʻohana i nā pā lithium i ke kikowaena mana portable.A aia ʻelua mau mea hana kemika nui, ʻo Nickel Manganese Cobalt (NMC) a me ka lithium iron phosphate (LFP).
No ka laʻana, hiki iā mākou ke ʻike i kēlā LFP no ka muliwai EcoFlow 2 pro, Anker power house 555 a me Bluetti AC200P, NMC no Goalzero YETI1500X a me EcoFlow DELTA mini.Ma ke ala, ʻaʻole hiki iaʻu ke haʻi i ke kemika o nā huahana a Jackery no ka mea ʻōlelo wale ʻo Lithium-ion.
No laila eia ka nīnau, ʻO wai kemika pākaukau e koho ai i ke kūʻai ʻana i kahi kikowaena uila?
Ma mua o ka pane ʻana i kēia nīnau, pono mākou e ʻimi mua i nā ʻano kemika o kēia mau ʻano pila ʻelua a hana i nā koho kūʻai e pili ana i kā mākou pono maoli.E hoʻohālikelike mākou i nā mea ʻelua mai nā ʻano ʻekolu: ka nui o ka ikehu, palekana, a me ke ola pōʻai.
No laila, ʻo ka ʻokoʻa mua ka ikehu, e hoʻohana wau iā Growatt i kumu hoʻohālike e hōʻike ai.Lawe ʻia kēia mau kikoʻī mai ka pūnaewele Growatt.Me ka nui like, hiki i ka NMC based 1500 ka mana 1512wh, a he 33 paona kona kaumaha, a ʻo ka LFP based 1300 ka mana he 1382wh akā he 42 paona.No laila, ʻoi aku ka kiʻekiʻe o ka ikehu kiʻekiʻe o nā ʻeke NMC ma mua o nā pā LFP.ʻO ia ke ʻano hiki iā lākou ke mālama i ka ikehu ma kēlā me kēia ʻāpana kaumaha a i ʻole ka leo, e hopena i ka lōʻihi o ke ola pākaukau a me ka puka mana kiʻekiʻe.
Nā hiʻohiʻona o GROWATT
ʻO ka ʻokoʻa ʻelua ka palekana.He mau hiʻohiʻona palekana maikaʻi nā pila NMC, akā ʻoi aku ka maʻalahi o ka holo ʻana i ka wela a me nā pōʻino ahi, ʻoi aku ka maikaʻi i ka wā i ʻike ʻia i nā wela kiʻekiʻe a i ʻole nā poino kino.Hoʻohui nā mea hana i nā ʻano hana palekana e hoʻēmi i kēia mau pilikia, e like me nā ʻōnaehana hoʻokele pākaukau kiʻekiʻe (BMS).
Ua manaʻo ʻia ʻoi aku ka palekana o nā pākahi LFP ma mua o nā pākahi lithium ternary.Loaʻa iā lākou ke kūpaʻa wela a ʻoi aku ka liʻiliʻi o ka wela a i ʻole ke ahi.ʻO ka hao phosphate he haʻahaʻa haʻahaʻa e hoʻoheheʻe ʻia i nā wela kiʻekiʻe, e hāʻawi ana i ka ʻike palekana holoʻokoʻa o ka pākaukau.
No laila, ʻaʻohe ʻokoʻa nui o nā pā uila NMC a me LFP i ka palekana no ka BMS kiʻekiʻe.
ʻO ka ʻokoʻa nui hope loa ke ola pōʻaiapili.E nānā i kēia palapala, ua helu au i kekahi mau hiʻohiʻona kaulana a me nā ʻāpana o Genki, e ʻike ʻoe ua helu ʻia nā hiʻohiʻona LFP e like me Genki no 3000 cycles a hiki i ka 80% hiki, a ʻo nā hiʻohiʻona NMC he 500 cycles.Hoʻomaka ka pōʻaiapuni ma 100 a hiki i 0, hoʻi i 100%, hoʻokahi pōʻaiapuni ia.No laila inā ʻoe i hana i kēlā me kēia lā, hiki iā ʻoe ke hoʻohana i nā huahana LFP ma luna o 9 mau makahiki.E hele ana ʻoe ma kahi o 6 mau manawa lōʻihi ma mua o nā kikowaena mana o NMC.
Hoʻohālikelike ʻāpana
No laila, i ka hōʻuluʻulu manaʻo, ʻoi aku ka nui o ka ikehu o nā ʻāpana NMC ma mua o ka LFP, a ʻoi aku ka lōʻihi o ke ola ʻana o nā pākahi LFP ma mua o NMC, a ʻoi aku ka maikaʻi o ka hana palekana ma muli o ka ʻōnaehana hoʻokele pākaukau holomua.
E hoʻi i ka nīnau, ʻO wai kemika pākaukau e koho ai i ke kūʻai ʻana i kahi kikowaena uila?NMC a i ʻole LFP?E koho i nā huahana i kūpono iā ʻoe e pili ana i kāu mau pono maoli a me ke kumukūʻai kumukūʻai.
