Ko ngā pākahiko o te waka hiko te wāhanga utu nui rawa atu o tētahi waka hiko.
Nā te nui o te utu, he nui ake te utu o ngā waka hiko i ētahi atu momo wahie, ā, e whakaroa ana tēnei i te whakamahinga nui o ngā EV.
Ritiumu-ion
Ko ngā pākahiko lithium-ion te mea tino rongonui. Engari kaua e kōrero nui atu, ka tukuna, ka whakakīia anō hoki i te mea ka haria e te electrolyte ngā katote lithium kua whakakīia pai mai i te anode ki te cathode, me te ritenga kē. Heoi anō, ka rerekē pea ngā rauemi e whakamahia ana i roto i te cathode i waenga i ngā pākahiko lithium-ion.
Ko te LFP, te NMC, me te NCA he matū iti e toru o ngā pākahiko Lithium-ion. Ka whakamahia e te LFP te Lithium-phosphate hei rauemi katote; ka whakamahia e te NMC te Lithium, te Manganese, me te Cobalt; ā, ka whakamahia e te NCA te Nickel, te Cobalt me te Aluminium.
Ngā painga o ngā pākahiko Lithium-ion:
● He iti ake te utu o te hanga i ngā pākahiko NMC me NCA.
● He roa ake te ora – ka tukuna he 2,500-3,000 huringa utu/tukunga katoa, ki te whakaritea ki te 1,000 mō ngā pākahiko NMC.
● He iti ake te wera e puta i te wā e utu ana kia roa ake ai te tere o te hiko e mau ana ki roto i te pihi utu, ka tere ake te utu me te kore e pakaru te pākahiko.
● Ka taea te utu ki te 100% me te iti o te pakaru o te pākahiko nā te mea ka āwhina i te whakatikatika i te pākahiko me te whakarato i ngā whakatau tata tika ake - Ko te hunga whai pākahiko LFP Tauira 3 me pupuri te rohe utu ki te 100%.
I te tau kua hipa, i tukuna e Tesla ki ana kiritaki Model 3 i Amerika he kōwhiringa i waenga i te pākahiko NCA, i te pākahiko LFP rānei. He 117kg te mama ake o te pākahiko NCA, ā, he 10 maero te tawhiti atu, engari he roa ake te wā e whakamahia ana. Heoi, e taunaki ana hoki a Tesla kia 90% noa iho o tōna kaha te utu mō te pākahiko NCA. Arā, ki te mea kei te whakaaro koe ki te whakamahi i te whānuitanga katoa i ngā wā katoa, ko te LFP tonu pea te kōwhiringa pai ake.
Waihāriki nikara-whakarewa
Ko ngā pākahiko nikara-whakarewa waikura (whakarāpopototanga ki NiMH) anake te mea hei whakakapi i ngā pākahiko lithium-ion kei te mākete i tēnei wā, ahakoa e kitea ana i roto i ngā waka hiko ranu (te nuinga o Toyota) he rerekē ki ngā waka hiko parakore.
Ko te take matua mō tēnei he 40% te iti iho o te mātotoru pūngao o ngā pākahiko NiMH i ngā pākahiko lithium-ion.
