Te whanonga whakawhiti wera o te pākahiko Lithium-ion me te hoahoa whakahaere waiariki

Na te pikinga o te hokonga me te mana o nga waka hiko hou, ka puta ano nga aitua ahi o nga waka hiko hou i ia wa.Ko te hoahoatanga o te punaha whakahaere waiariki he raruraru pounamu e aukati ana i te whanaketanga o nga waka hiko hou.Ko te hoahoa i tetahi punaha whakahaere waiariki pumau me te whai hua he mea nui hei whakapai ake i te haumaru o nga waka hiko hou.

Ko te whakatauira waiariki pākahiko Li-ion te kaupapa o te whakahaere waiariki pākahiko Li-ion.I roto i a raatau, ko te whakatauira ahuatanga whakawhiti wera me te whakatauira ahuatanga whakangao wera e rua nga waahanga nui o te whakatauira waiariki pākahiko lithium-ion.I roto i nga rangahau o naianei mo te whakatauira i nga ahuatanga whakawhiti wera o nga pākahiko, e kiia ana ko nga pākahiko lithium-ion he kawe wera anisotropic.Na reira, he mea nui ki te ako i te awe o nga waahi whakawhiti wera rereke me nga waahi whakawhiti wera i runga i te wera o te wera me te wera o nga papahiko lithium-ion mo te hoahoa o nga punaha whakahaere waiariki pai me te pono mo nga papahiko lithium-ion.

Ko te 50 A·h lithium iron phosphate pūtau pūtau i whakamahia hei ahanoa rangahau, ā, i āta tātarihia ngā āhuatanga whanonga whakawhiti wera, ā, i whakaarohia he whakaaro hoahoa whakahaere waiariki hou.Ko te ahua o te pūtau e whakaatuhia ana i te Whakaahua 1, me nga tawhā rahi motuhake e whakaatuhia ana i te Ripanga 1. Ko te hanganga pākahiko Li-ion i te nuinga o te waa kei roto i te hiko pai, te hiko kino, te electrolyte, te whakawehe, te arahi hiko pai, te arahi hiko kino, te taunga pokapū, he mea whakamarumaru, he paera haumaru, he whakarea pāmahana pai (PTC)(PTC whakamahana whakamahana/PTC Air Heater) whakamaarama me te pouaka pākahiko.Ka whakawhäitihia he kaiwehewehe i waenga i nga pou pai me te kino, a ka hangaia te matua o te pākahiko ma te awhiowhio, ka hangaia ranei te roopu pou ma te raima.Whakangwarihia te hanganga pūtau papa-maha ki roto i te rauemi pūtau he rite te rahi, me te mahi i te maimoatanga rite ki nga tawhā thermophysical o te pūtau, pera i te Whakaaturanga 2. Ko te rauemi pūtau pākahiko e kiia ana he waeine putorino me nga ahuatanga kawe werawera anisotropic. , ka whakatauhia kia iti ake te kawe waiariki (λz) e tika ana ki te ahunga whakapapa i te whakarara (λ x, λy) e whakarara ana ki te ahunga whakapapa.

(1) Ko te kaha tohanga wera o te kaupapa whakahaere waiariki lithium-ion pākahiko ka pangia e nga tawhā e wha: ko te kawe i te waiariki e tika ana ki te mata o te wera, te tawhiti o te huarahi i waenga i te pokapū o te puna wera me te mata o te wera, te te rahi o te mata tohanga wera o te kaupapa whakahaere waiariki, me te rereketanga o te pāmahana i waenga i te mata tohanga wera me te taiao a tawhio noa.

(2) I te wa e whiriwhiri ana i te mata tohanga wera mo te hoahoa whakahaere waiariki o nga pākahiko lithium-ion, ko te kaupapa whakawhiti wera taha o te mea rangahau kua tohua he pai ake i te kaupapa whakawhiti wera o raro, engari mo nga pākahiko tapawha o nga rahi rereke, he mea tika. ki te tatau i te kaha tohanga wera o nga mata tohanga wera rereke kia taea ai te whakatau i te waahi whakamatao pai rawa atu.

(3) Ka whakamahia te tauira ki te tatau me te arotake i te kaha tohanga wera, a ka whakamahia te whaihanga tau ki te manatoko he tino rite nga hua, e tohu ana he whai hua te tikanga tatauranga ka taea te whakamahi hei tohutoro i te wa e hoahoa ana te whakahaere waiariki. o ngā pūtau tapawhā.(BTMS)
