He aha te kaha o te pākahiko?
Ko te kaha o te pākahiko ko te nui o te utu hiko ka taea e ia te tuku i te ngaohiko kāore e heke iho i raro i te ngaohiko pito kua tohua. Ko te kaha ka whakahuatia i roto i ngā hāora-ampere (A·h) (mAh mō ngā pākahiko iti). Ko te whanaungatanga i waenga i te iahiko, te wā tuku me te kaha ka whakatauhia (i runga i te whānuitanga o ngā uara iahiko) māTe ture a Peukert:
t = Q/I
tko te roa o te wā (i roto i ngā hāora) ka taea e te pākahiko te pupuri.
Qko te kaha.
Iko te iahiko e tangohia ana mai i te pākahiko.
Hei tauira, ki te whakamahia te rama rā, ko tōna kaha pākahiko he 7Ah, me te iahiko 0.35A, ka taea te whakamahi mō te 20 hāora. Ā, e ai ki teTe ture a Peukert, ka taea e tātou te mōhio mēnāHe nui ake te kaha o te pākahiko o te rama rā, ā, ka roa ake te wā e whakamahia anaĀ, ka taea e te kaha pākahiko o te rama tiriti rā raupapa Liper D te eke ki te 80Ah!
Me pēhea te whakarite a Liper i te kaha o te pākahiko?
Ko ngā pākahiko katoa e whakamahia ana i roto i ngā hua Liper he mea hanga e mātou. Ā, ka whakamatautauria e tā mātou mīhini ngaio e utu ana, e tuku ana hoki i ngā pākahiko mō ngā wā e rima. (Ka taea hoki te whakamahi i te mīhini hei whakamātautau i te roa o te porowhita o te pākahiko)
Haunga tēnā, ka whakamahia e mātou te phosphate rino lithium (LiFePO4)4) te hangarau pākahiko kua whakamātauhia ka taea e ia te whakarato i te utu tere me te tuku hiko, ka tukuna katoatia tōna kaha ki roto i te kawenga i roto i te 10 ki te 20 hēkona i te whakamātautau i te tau 2009. Ki te whakatauritea ki ētahi atu momo pākahiko,He haumaru ake te pākahiko LFP, ā, he roa hoki tōna ora.
He aha te whai huatanga o te papa rā?
He taputapu te panera rā e huri ana i te hihi o te rā hei hiko mā te whakamahi i ngā pūtau photovoltaic (PV). Ā, ko te whai huatanga o te panera rā ko te wāhanga o te pūngao i roto i te āhua o te hihi o te rā ka taea te huri mā te photovoltaics hei hiko e te pūtau rā.
Mō ngā hua pūngao rā o Liper, ka whakamahia e mātou he panera pūngao rā silicon mono-crystalline. Me te pai o te mahi taiwhanga pūtau kotahi-hononga kua tuhia o26.7%, ko te silicon mono-crystalline te mea tino whai hua o te huringa kua whakaūtia i roto i ngā hangarau PV arumoni katoa, i mua i te poly-Si (22.3%) me ngā hangarau kiriata angiangi kua whakapumautia, pēnei i ngā pūtau CIGS (21.7%), ngā pūtau CdTe (21.0%), me ngā pūtau a-Si (10.2%). Ko te whai hua o te kōwae rā mō te mono-Si—he iti iho i ngā pūtau e rite ana—i te mutunga i whiti i te tohu 20% mō te tau 2012, ā, i eke ki te 24.4% i te tau 2016.
Hei whakarāpopototanga, kaua e aro noa ki te hiko ina hiahia koe ki te hoko hua pūngao rā! Kia aro ki te kaha o te pākahiko me te whai huatanga o te panera rā! Ko Liper te kaihanga o ngā hua pūngao rā pai rawa atu māu i ngā wā katoa.
