Lithium rino Phosphate pākahiko: te āhuatanga, tono

taputapu Modern Kei te hoko matatini ake me kaha nga ra. paerewa hangarau High hanga titauraa teitei ki te pākahiko e hiahia inaianei ki te ngā mahi nui, pūngao kakama, ka whai i te nui haere supply o te hiko.

Ko te kupu whakataki o ngā momo hou o te hanga taputapu hiko, te whakaterenga o te tukanga - faarahi tenei katoa ki hiko tono, a kore e taea pākahiko hou te whakatau tonu ratou. Hei whakaoti i tēnei raruraru, kua whiriwhiria ngā kaiwhakanao ki te whakapai ake i te hangarau lithium-katote. Ko te kupu i whanau i te pākahiko lithium rino Phosphate (LiFePO4), i te mea he uri wä o pākahiko Li-katote.

mōhiohio hītori

LiFePO4, ranei LFP, - kohuke māori olivine whānau, i kitea tuatahi i roto i te tau 1996 e te pūtaiao i te University o Texas, John Goodenough, nei i rapu mō huarahi ki te whakapai ake i te puna mana Li-katote. Rongonui ko te meka e te kohuke kua he tāoke raro me te pūmautanga teitei waiariki atu tetahi mohiotia i te wa nga electrodes.

Haunga tutaki i te reira i roto i te taiao māori, me i he utu raro. Ko te drawback matua o nga electrodes i runga i te pūtake o LiFePO4 ko te kaha hiko iti, i te mea he aha kua mutu lithium pūhiko rino Phosphate ki kia whakawhanakehia.

Rangahau i roto i tenei aronga i anō i roto i te tau 2003 i te Institute o Technology Massachusetts. He rōpū o pūtaiao mahi i runga i te hanganga o te pūhiko faufaa hou e e riro i te whakakapinga mō te matatau tino i taua pākahiko wa, Li-katote. Ko te kaupapa hiahia i roto i te kamupene nui pērā i Motorola ko Qualcomm o, i kawea mai te putanga o te pūhiko ki huānga LiFePO4 pitoiho.

LiFePO4 pākahiko i runga i te pūtake o

Ka whakamahia e tēnei momo o pūhiko te taua hangarau ki te whakaputa i te hiko, me te pūtau lithium-katote mua mo tatou. Heoi, i reira e he maha o nui ngā rerekētanga i waenganui i a ratou. Tuatahi, ko te ki te whakamahi i tona momo ake o BMS - pūnaha whakahaere e tiaki te pūhiko hiko i overcharging me rere hohonu, whakapai ake mauroa me te hanga atu pūmau te puna pūngao.

Tuarua, LiFePO4, pērā LiCoO2, he iti paitini. Tenei meka whakaaetia ki te karo i etahi o nga raruraru e pā ana ki poke taiao. I roto i ngā ki te whakaiti i te tukunga konukurahina tika ki tikanga hē o ngā pākahiko.

I te pae hopea, e tika ana ki te kore o ngā paerewa kotahi huānga LFP i tito matū rerekē, e ai tauira rerekētanga mahinga i runga i te whānuitanga whanui. I tua atu, enei kai tiaki te mana ake uaua, me te kia meatia i roto i te hanganga ture ki etahi ture.

āhuatanga hangarau

Kei te mea te reira e kua whakaputaina lithium rino Phosphate pākahiko 48 volts, 36 volts me 60 volts i raupapa takotoranga i te pūtau kotahi, no te mea e kore ai te ngaohiko mōrahi i roto i te kotahi LFP-wāhanga nui 3,65 V. reira, te mahi o ia pūhiko kia tino rerekē i ia atu - te reira i katoa tei runga i te whakaminenga, me te hanganga ngā matū.

Hoki tātari Mahinga tapae uara iti o tetahi pūtau kotahi.

Kua tae te iteraa pai o te pūmanawa o ia pūtau takitahi i roto i te pūhiko Everexceed. Lithium rino Phosphate pūhiko Everexceed rerekē te ora roa. ratou e nehenehe e te tu katoa ki runga, ki te 4 mano huringa Akona-rere. ki te mate o te kaha o runga ki te 20%, me te ētahi o rokiroki pūngao e wahi i roto i te 12 meneti. Homai tenei, ka taea e tatou e faaoti e Everexceed pūhiko e tetahi o nga māngai pai o te LFP-huānga.

Huapai me ngā huakore

Ko te painga matua o taua i roto i te marama pai ngā te Phosphate pākahiko lithium rino, i roto i te tahi atu māngai o te CRA, he pikinga. taea ki te tu atu neke atu i te 3 mano huringa tiaki-rere i te taumata mana he huānga taua he pata ki te 30%, me te neke atu i te 2 mano - .. Ki te maturuturu iho ki te 20%. No te mea o tenei ko āhua i te ora pūhiko toharite 7 tau.

nāianei ka tohutohutia pūmau ko te rua o nga painga nui o LFP-huānga. tonu rite ki te 3.2 V te ngaohiko whakaputa noa ko tino ruha te tiaki. Simplifies tenei te waea, te whakakore i te hiahia mō ngā tauwehe ngaohiko.

Higher tihi o nāianei - te tuatoru o painga ratou. Tēnei āhuatanga e āhei te pūhiko ki hoatu ratou mana mōrahi noa i pāmahana tino iti. Kua ākina tēnei taonga kaiwhakanao waka ki te whakamahi i lithium pūhiko rino Phosphate rite te puna mana tuatahi ka tīmata penehīni me te diesel engines.

Fakataha ki nga painga katoa, LiFePO4 pākahiko i kotahi drawback nui - he puranga nui me āhuatanga. E whakaiti ana tēnei i to ratou whakamahi i roto i etahi momo o te mīhini me te taputapu hiko.

Āhuatanga o te mahi

Ki te hoko koe i rite-hanga pākahiko lithium-Phosphate, e kore nga fifi ki te tiaki me te mahi ka whai koutou. whakawhetai katoa ki te meka e kua whakaurua nga kaihanga o taua huānga ki poari BMS e ārai i overcharging me te ārai huānga rere ki te taumata i raro.

Otiia, ki te hoko koe pūtau takitahi (pākahiko penlight, mo te tauira), ka whai koe ki te pupuri i te kanohi i runga i te mana pūhiko anake. A, no te makaka tiaki i raro i te taumata tino (2.00 V i raro) ka tere hinga me te puritanga, hanga reira taea ki te recharge te pūtau. Ki te koe, i runga i te anga ke, kia taimaha (i runga 3.75 V), te pūtau kua tupu te noa e tika ana ki te haurehu tukua.

Ki te kei te whakamahi koe i te pākahiko taua mo te waka hiko, i muri i te 100% tohutohutia me momotu e koe te rihi pākahiko. Kore, putapu te pūhiko e tika ana ki te supersaturation o electrocution.

ture whakahaere

Ki te whakamahere koe ki te whakamahi i te pākahiko lithium-Phosphate i roto i te aratau huringa me te i roto i te moka, mo te tauira, kia rite ki te puna o te mana-ake ranei i roto i te taha ki te pākahiko solar, e hiahia ana koe ki te tango i te tiaki o tukupu te taumata o te tiaki ki te 3.40-3.45 V. akakoromaki ki tauturu tenei mahi peihana 'atamai' e aunoa tuatahi tino utu mo te supply o te pūngao, me ka raro i te taumata ahotea.

I roto i te mahi, e hiahia ana koe ki te aroturuki i te toenga o ngā pūtau te whakamahi o te utu whärite motuhake (i roto i te pūhiko, kua hanga ratou mo te waka hiko) ranei. tāne i pūtau huaina te āhua taua, ina ko te katoa ngaohiko o te pūrere i te taumata iti, engari riro rerekē te ngaohiko pūtau.

Tenei āhuatanga Ko e tika ana ki te rerekētanga o te parenga o ngā wāhanga takitahi, therebetween whakapā rawakore. Ki te whai i te pūtau ngaohiko rerekē, me te mea ratou pāhiwihiwi tiaki-rere, e tino whakaiti te ora mahi o te pūhiko.

Te tuku i te pūhiko ki te mahi

I mua i te whakamahi i te pākahiko lithium Phosphate huihui i ngā pūtau motuhake, me tiaki e tangohia pūnaha whärite, rite taea te wāhanga i te taumata tiaki rerekē. Hoki tenei whakaaro, e toaati wāhanga katoa i roto i te whakarara, me te e hono ki te rectifier, he rihi. United kupu ko reira e tika ana ki te ako atu i te pūtau ki 3.6 V.

Mā te pūhiko Phosphate lithium rino mo te pahikara hiko, pea ite koe e i roto i te meneti tuatahi o te pūhiko homai te kaha mōrahi, a ka te tere hinga te tiaki ki te taumata o 3.3-3.0 V. kaua e wehi o tenei, no te mea ko reira te mahi noa o te pūhiko . Ko te meka e te nuinga o tona kaha (e pā ana ki 90%) takoto i roto i tēnei awhe.

mutunga

Te kaha pākahiko lithium-Phosphate ko 20-30% runga ake i taua o te tahi atu pākahiko. I te wa ano ratou mahi hoki 2-3 tau roa atu i ētahi atu puna mana, me te whakarato i te nāianei pūmau i runga i te wā katoa o te mahi. tenei katoa miramira te āhuatanga aroaro i roto i te marama pai.

Heoi, ka tukunoa'i nuinga o te iwi, me te lithium rino Phosphate pākahiko. Pai me ngā raruraru o te pūhiko koma i mua i te utu ratou - ko reira 5-6 wa, nui atu i te mua mo ki tatou no te arata'i-waikawa pūtau. utu tenei pūhiko motokā te toharite o e pā ana ki 26 mano. moni.
