Kei te haere mai te puranga utu DC mana-teitei

E ai ki te whanaketanga o te hangarau utu waka hiko me te hiahia mō te utu tere, i whakaritea e te Manatū Ahumahi me te Hangarau Mōhiohio te Komiti Hangarau Paerewa Motuka ā-Motu hei whakaoti i te arotakenga o ngā paerewa ā-motu e rua kua tūtohutia, kia tutuki ai he whakahoutanga hou ki te putanga taketake o te tau 2015 o te kaupapa paerewa ā-motu (e mōhiotia whānuitia ana ko te paerewa "2015 +"), he mea whai hua ki te whakapai ake i te urutau taiao, te haumaru me te pono o ngā taputapu hononga utu hiko, me te whakatutuki i ngā hiahia tuturu o te utu hiko iti-mana DC me te utu hiko teitei.

I te taahiraa e whai ake nei, ka whakarite te Manatū Ahumahi me te Hangarau Mōhiohio i ngā wāhanga e tika ana hei whakahaere i te whakatairanga hohonu, te whakatairanga me te whakatinanatanga o ngā paerewa ā-motu e rua, te whakatairanga i te whakatairanga me te tono o te utu hiko DC teitei me ētahi atu hangarau, me te waihanga i tētahi taiao whanaketanga kounga teitei mō te umanga waka hiko hou me te umanga whare utu. He taiao pai. Ko te utu puhoi he tino raruraru i roto i te umanga waka hiko.

E ai ki tētahi pūrongo a Soochow Securities, ko te tere utu ā-arotake toharite o ngā tauira hokohoko rongonui e tautoko ana i te utu tere i te tau 2021 he tata ki te 1C (ko C te tere utu o te pūnaha pākahiko. Ki te kīanga māmā noa, ka taea e te utu 1C te utu katoa i te pūnaha pākahiko i roto i te 60 meneti), arā, e 30 meneti te roa o te utu hei whakatutuki i te SOC 30%-80%, ā, ko te roa o te ora o te pākahiko he tata ki te 219km (paerewa NEDC).

I roto i te mahi, ko te nuinga o ngā waka hiko parakore e hiahia ana kia 40-50 meneti te utu hei whakatutuki i te SOC 30%-80%, ā, ka taea te haere i te 150-200km. Mena ka whakaurua te wā ki te tomo me te wehe atu i te teihana utu (tata ki te 10 meneti), ka taea e te waka hiko parakore e tata ana ki te 1 hāora te utu te taraiwa i runga i te huarahi nui mo te neke atu i te 1 hāora.

Ko te whakatairanga me te whakamahi i ngā hangarau pēnei i te utu hiko DC kaha-teitei ka hiahiatia he whakapai ake i te whatunga utu a meake nei. I mua ake nei, i whakapuaki te Manatū Pūtaiao me te Hangarau kua hangaia e tōku whenua he whatunga whare utu me te nui rawa o ngā taputapu utu me te rohe hipoki nui rawa atu. Ko te nuinga o ngā whare utu tūmatanui hou he taputapu utu tere DC me te 120kW, neke atu rānei.Ngā puranga utu puhoi 7kW ACkua noho hei paerewa i roto i te rāngai tūmataiti. Kua rongonui haere te whakamahinga o te utu tere DC i roto i te mara o ngā waka motuhake. He whatunga tūāpapa kapua kei ngā whare utu tūmatanui hei aroturuki i te wā-tūturu. Kua whānuitia te whakamahinga o ngā āheinga, te kimi puranga APP me te utu ipurangi, ā, kei te whanake haere ngā hangarau hou pēnei i te utu hiko teitei, te utu hiko DC iti-mana, te hononga utu aunoa me te utu tika.

Ā tōna wā, ka arotahi te Manatū Pūtaiao me te Hangarau ki ngā hangarau me ngā taputapu matua mō te utu me te whakawhiti mahi tahi whai hua, pērā i ngā hangarau matua mō te hononga kapua puranga waka, ngā tikanga whakamahere whare utu me ngā hangarau whakahaere utu tika, ngā hangarau matua mō te utu ahokore mana-teitei, me ngā hangarau matua mō te whakakapinga tere o ngā pākahiko hiko. Whakakaha ake i te rangahau pūtaiao me te hangarau.

I tētahi atu taha,te utu DC mana-teiteika whakatō i ngā whakaritenga teitei ake mō te mahi a ngā pākahiko hiko, arā, ngā wāhanga matua o ngā waka hiko.

E ai ki te tātaritanga a Soochow Securities, tuatahi, ko te whakanui ake i te tere utu o te pākahiko he rerekē ki te mātāpono o te whakanui ake i te kiato pūngao, nā te mea ko te tere teitei e hiahia ana ki ngā matūriki iti ake o ngā rauemi irahiko pai me te kino o te pākahiko, ā, ko te kiato pūngao teitei e hiahia ana ki ngā matūriki nui ake o ngā rauemi irahiko pai me te kino.

Tuarua, ko te utu tere nui i te āhua mana nui ka nui ake ngā tauhohenga taha o te whakatakotoranga lithium me ngā pānga whakaputa wera ki te pākahiko, ka iti ake te haumaru o te pākahiko.

I roto i ēnei, ko te rauemi hiko kino o te pākahiko te mea matua e whakawhāiti ana i te utu tere. Nā te mea he mea hanga te karāpeti hiko kino ki ngā rau karāpene, ā, ka uru ngā katote lithium ki roto i te rau mā ngā taha. Nō reira, i te wā o te utu tere, ka tere te eke o te hiko kino ki te rohe o tōna kaha ki te mimiti i ngā katote, ā, ka tīmata ngā katote lithium ki te hanga i te konutai lithium totoka ki runga i ngā matūriki karāpeti, arā, ka puta he tauhohenga taha o te maturuturunga o te Lithium. Ka whakaitihia e te maturuturunga o te Lithium te horahanga whai hua o te hiko kino hei whakauru i ngā katote lithium. I tetahi taha, ka whakaitihia te kaha o te pākahiko, ka whakanui ake i te ātete o roto, ā, ka whakapoto i te roanga o te ora. I tetahi atu taha, ka tipu ngā tioata atanga ka wero i te wehewehe, ka pā ki te haumaru.

Kua tuhituhia anō hoki e Ahorangi Wu Ningning me ētahi atu o Shanghai Handwe Industry Co., Ltd. i mua, hei whakapai ake i te kaha utu tere o ngā pākahiko hiko, me whakanui ake te tere o te hekenga o ngā katote lithium ki roto i te rauemi katote pākahiko, me te tere ake te whakaurunga o ngā katote lithium ki roto i te rauemi anode. Whakapai ake i te kawe irahiko o te electrolyte, whiriwhiria he wehewehe utu tere, whakapai ake i te kawe irahiko me te hiko o te electrode, me te whiriwhiri i tētahi rautaki utu tika.

Heoi, ko tā ngā kaihoko e tumanako atu nei, mai i te tau kua hipa, kua tīmata ngā kamupene pākahiko ā-rohe ki te whakawhanake me te whakamahi i ngā pākahiko utu tere. I te marama o Ākuhata o tēnei tau, i tukuna e te CATL matua te pākahiko utu nui 4C Shenxing i runga i te pūnaha phosphate rino lithium pai (ko te tikanga o te 4C ka taea te utu katoa i te pākahiko i roto i te hauwhā o te haora), ka taea te whakatutuki i te "10 meneti o te utu me te whānuitanga o te 400 kw" Tere utu tere rawa. I raro i te pāmahana noa, ka taea te utu i te pākahiko ki te 80% SOC i roto i te 10 meneti. I taua wā anō, ka whakamahia e te CATL te hangarau whakahaere pāmahana pūtau i runga i te tūāpapa pūnaha, ka taea te wera tere ki te awhe pāmahana mahi tino pai i roto i ngā taiao pāmahana iti. Ahakoa i roto i te taiao pāmahana iti o te -10°C, ka taea te utu ki te 80% i roto i te 30 meneti, ā, ahakoa i roto i ngā ngoikoretanga pāmahana iti, kāore te whakaterenga tere kore-rau-rau e pirau i roto i te āhua hiko.

E ai ki a CATL, ka hangaia papatipu ngā pākahiko whakakaha nui a Shenxing i roto i tēnei tau, ā, koinei te tuatahi ka whakamahia i roto i ngā tauira Avita.

 

Kua whakarewahia hoki te tauira hiko parakore tino pai i tēnei tau e te pākahiko utu tere 4C Kirin a CATL i hangaia i runga i te rauemi katote lithium toru, ā, nō nā tata nei i whakarewahia ai te motuka hopu tino papai rawa atu, 001FR.

Haunga a Ningde Times, me ētahi atu kamupene pākahiko ā-rohe, kua whakatakotohia e China New Aviation ngā ara e rua, he tapawhā me he porotaka nui, i roto i te mara o te utu tere ngaohiko-teitei 800V. Ka tautokohia e ngā pākahiko tapawhā te utu tere 4C, ā, ka tautokohia e ngā pākahiko porotaka nui te utu tere 6C. Mō te otinga pākahiko prismatic, ka whakaratohia e China Innovation Aviation ki a Xpeng G9 he whakatupuranga hou o ngā pākahiko rino lithium utu tere me ngā pākahiko toru ngaohiko-teitei nikara-waenga i whakawhanakehia i runga i te tūāpapa ngaohiko-teitei 800V, ka taea te whakatutuki i te SOC mai i te 10% ki te 80% i roto i te 20 meneti.

I tukuna e Honeycomb Energy te Pūhiko Dragon Scale i te tau 2022. E hototahi ana te pūhiko ki ngā otinga pūnaha matū katoa pērā i te rino-litium, te ternary, me te kore-cobalt. E hipokina ana e ia ngā pūnaha utu tere 1.6C-6C, ā, ka taea te tāuta ki ngā tauira raupapa A00-D. E matapaetia ana ka tukuna te tauira ki te hanga papatipu i te hauwhā tuawhā o te tau 2023.

Ka tukuna e Yiwei Lithium Energy tētahi pūnaha pākahiko porotaka nui π i te tau 2023. Ka taea e te hangarau whakamatao "π" o te pākahiko te whakaoti i te raruraru o te utu tere me te whakamahana i ngā pākahiko. E matapaetia ana ka hangaia papatipu ana pākahiko porotaka nui 46 raupapa ka tukuna i te hauwhā tuatoru o te tau 2023.

I te marama o Ākuhata o tēnei tau, i kōrero anō a Sunwanda Company ki ngā kaipupuri moni ka taea te whakarerekē i te pākahiko "flash charge" e whakarewahia ana e te kamupene mō te mākete BEV ki ngā pūnaha ngaohiko teitei 800V me te ngaohiko noa 400V. Kua tutuki i ngā hua pākahiko 4C tino tere te utu i te hauwhā tuatahi. Kei te pai te haere o te whanaketanga o ngā pākahiko "flash charging" 4C-6C, ā, ka taea e te horopaki katoa te whakatutuki i te roa o te pākahiko o te 400 kw i roto i te 10 meneti.
