ʻO ka piʻi ʻana o nā kumukūʻai ikehu ma ʻEulopa ʻaʻole ia i alakaʻi i ka boom i ka mākeke PV rooftop i hoʻohele ʻia, akā ua hoʻoikaika pū kekahi i ka ulu nui ʻana i nā ʻōnaehana mālama uila home.Ka hoike oMākeʻaka ʻEulopa no ka mālama ʻana i nā Batri Noho2022-2026i paʻi ʻia e SolarPower Europe (SPE) ʻike i ka makahiki 2021, ma kahi o 250,000 mau ʻōnaehana mālama ikehu pākaukau i hoʻokomo ʻia e kākoʻo i nā ʻōnaehana ikehu lā o ʻEulopa.ʻO ka mākeke mālama ʻana i ka ikehu pā hale ʻEulopa ma 2021 a hiki i 2.3GWh.Ma waena o ia mea, ʻo Kelemania ka ʻāpana mākeke nui loa, ʻo 59% ka helu, a ʻo ka hiki ke mālama i ka ikehu hou he 1.3GWh me ka piʻi o ka ulu makahiki o 81%.
Ua manaʻo ʻia ma ka hopena o 2026, e hoʻonui ʻia ka nui o ka nui o nā ʻōnaehana mālama ikehu home ma mua o 300% a hiki i 32.2GWh, a ʻo ka nui o nā ʻohana me nā ʻōnaehana mālama ikehu PV e hiki i 3.9 miliona.
I loko o ka ʻōnaehana mālama ikehu home, ʻo ka pākaukau mālama ikehu kekahi o nā mea nui.I kēia manawa, noho nā pā lithium-ion i kahi kūlana kūʻai koʻikoʻi ma ke kahua o ka mālama ʻana i ka ikehu home ma muli o ko lākou mau hiʻohiʻona koʻikoʻi e like me ka liʻiliʻi liʻiliʻi, ke kaumaha māmā a me ke ola lawelawe lōʻihi.
I loko o ka ʻōnaehana pākaukau lithium-ion i hana ʻia i kēia manawa, ua hoʻokaʻawale ʻia ʻo ia i ka ternary lithium battery, lithium manganate battery a me ka lithium iron phosphate battery e like me ka mea electrode maikaʻi.Ke noʻonoʻo nei i ka hana palekana, ke ola pōʻaiapuni a me nā ʻāpana hana ʻē aʻe, ʻo nā pākahi lithium hao phosphate i kēia manawa ke kumu nui i nā ʻenekona mālama home.No nā pākahi lithium hao phosphate hale, ʻo nā hiʻohiʻona nui e pili ana i kēia:
- ghana palekana ood.I ka hiʻohiʻona noiʻi o ka pākaukau mālama home, he mea nui ka hana palekana.Ke hoʻohālikelike ʻia me ka pākahi lithium ternary, haʻahaʻa haʻahaʻa ka mana o ka pākaukau lithium iron phosphate, ʻo 3.2V wale nō, ʻoiai ʻoi aku ka kiʻekiʻe o ka wela o ka hoʻoheheʻe ʻana o ka mea ma mua o 200 ℃ o ka pākahi lithium ternary, no laila e hōʻike ana i ka hana palekana maikaʻi.I ka manawa like, me ka hoʻomohala hou ʻana o ka ʻenehana hoʻolālā pākaukau a me ka ʻenehana hoʻokele pākaukau, nui ka ʻike a me ka ʻenehana noiʻi pono i ka hoʻokele piha ʻana i nā pā lithium hao phosphate, ka mea i hāpai i ka hoʻohana ākea o nā pā lithium hao phosphate i loko. ke kahua o ka waihona ikehu hale.
- aʻokoʻa maikaʻi i nā pākaukau lead-acid.No ka manawa lōʻihi i ka wā i hala aku nei, ʻo nā pākahi ma ke kahua o ka mālama ʻana i ka ikehu a me ka hoʻihoʻi ʻana i ka mana hoʻihoʻi ka nui o nā pākaʻi lead-acid, a ua hoʻolālā ʻia nā ʻōnaehana hoʻokele e pili ana me ka pili ʻana i ka nui o ka volta o nā pākika lead-acid a lilo i mea pili i ka honua a me ka home. nā kūlana,.Ma nā ʻōnaehana pākahi lithium-ion a pau, ʻoi aku ka maikaʻi o nā pākahi lithium iron phosphate ma nā moʻo e hoʻokūkū maikaʻi loa i ka volta hoʻokuʻu ʻana o ka pākēneka lead-acid modular.No ka laʻana, ʻo ka volta hana o 12.8V lithium iron phosphate pākahiko ma kahi o 10V a i 14.6V, ʻoiai ʻo ka volta hana pono o 12V lead-acid pākahi ma waena o 10.8V a me 14.4V.
- Ke ola lōʻihi.I kēia manawa, i waena o nā pākaukau accumulator stationary a pau, ʻo nā pā lithium hao phosphate ka lōʻihi o ke ola pōʻai.Mai ka hiʻohiʻona o nā pōʻai ola o kēlā me kēia cell, ʻo ka pākaukau lead-acid ma kahi o 300 mau manawa, hiki i ka ternary lithium battery ke hiki i 1000 mau manawa, aʻo ka lithium iron phosphate battery hiki ke ʻoi aku ma mua o 2000 mau manawa.Me ka hoʻomaikaʻi ʻana i ke kaʻina hana, ke oʻo ʻana o ka ʻenehana lithium replenishment, a me nā mea ʻē aʻe, hiki i nā pōʻai ola o nā pahu lithium hao phosphate ke piʻi aku ma mua o 5,000 mau manawa a i ʻole 10,000 mau manawa.No nā huahana pākaukau mālama ikehu home, ʻoiai e kaumaha ʻia ka helu o nā pōʻai i kekahi ʻano (e loaʻa pū kekahi i nā ʻōnaehana pākaukau ʻē aʻe) ma ka hoʻonui ʻana i ka helu o kēlā me kēia cell ma o ka hoʻopili ʻana i ka moʻo (i kekahi manawa i ka like), nā hemahema o ka multi-series. a e hoʻoponopono hou ʻia nā ʻenekini multi-parallel ma o ka optimization o ka ʻenehana pairing, ka hoʻolālā huahana, ka ʻenehana hoʻoheheʻe wela a me ka ʻenehana hoʻokele hoʻokele pila i ka nui e hoʻomaikaʻi i ke ola lawelawe.
