He aha te BESS Modular e tuku ana i te ngāwari kore e rite mō ngā kaiwhakahaere

Whakautu Tere:He pūnaha rokiroki pūngao pākahiko modular (BESS) kua hangaia mai i ngā poraka hiko me ngā poraka pākahiko kua whakaritea, ka taea te whakakapi motuhake, kaua hei wae kotahi, e āhei ai ngā kaiwhakahaere ki te whakanui i te kaha i roto i ngā taahiraa e taea te matapae - hei tauira mai i te wae 120 kWh/60 kW ki te teihana 625 kWh/400 kW - mā te tāpiri i ngā wae rite. E whā ngā painga whakahaere a te modularity e kore e taea te whakataurite e ngā hoahoa monolithic: te whakapaunga whakapaipai utu-i-a-koe-te-tipu, te tiaki whakawhiti-wera e whakaiti ana i te wā kore mahi mai i ngā rā ki ngā hāora, te tauutuutu N+1 e pupuri ana i te pae ki te ipurangi i te wā e rahua ana ngā wāhanga, me te ngāwari o te whakatinanatanga puta noa i ngā whakatakotoranga tūmau, pūkoro, me te whakauru-rā mā te whakamahi i ngā taputapu matua kotahi. Mō ngā kaiwhakahaere waka me ngā pūwāhi utu, ka hurihia e te hoahoa modular te rokiroki mai i te haumi pumau, mōrearea ki roto i te rawa whakahaere tauine me te tere o te tono, te utu katoa iti iho o te mana, me te ara mārama ki te whakawhānui ake a meake nei.

Ngā Whakaaro Matua:

• Ka whakaitihia e te BESS modular te whakapaipai tuatahi mā te 40–60% ki te whakaritea ki tētahi pūnaha monolithic rahi rawa, nā te mea ka tāpirihia te kaha ina tika te whakamahinga.
• Mā ngā poraka pākahiko me te hiko kua whakaritea, ka taea te whakakapi i ngā taputapu me te whakawhiti wera, ka tere ake te wā whakatikatika mai i ngā rā ki ngā hāora, ā, ka whakaitihia hoki te nui o ngā wāhanga e manawapa ana.
• Ko te tikanga o te taurite o te kōwae N+1 ka iti ake te kaha o te kōwae hiko, pākahiko rānei e rahua ana, hei utu mō te tango i te pae katoa mai i te ipurangi.
• Ka taea te whakaneke i ngā poraka hiko taurite mai i te 60 kW/120 kWh whakairinga-pātū ki ngā teihana huarahi 400 kW/625 kWh — ā, ka neke i waenga i ngā whirihoranga tūmau, pūkoro, me ngā whirihoranga rokiroki-rā-me-te-pūmanawa.
• Mā te whiriwhiri a ngā kaiwhakahaere i ngā hoahoanga modular ka whakapotohia ngā wā arahi kaupapa, ka whakangāwari ake hoki i te hoko, te whakangungu, me te whakahaere pūtāhui puta noa i ngā wāhi maha.

Te Mahanga Monolithic: He aha i Pāngia ai ngā Kaiwhakahaere e te Pūhiko Nui Kotahi

I hiahiatia e te kaiwhakahaere ratonga kawe waka he 300 kW o te kaha utu waka, ā, i muri i te tohutohu a te kaitohutohu, i hokona e ia tētahi pūnaha rokiroki kotahi te rahi, 480 kWh, hei utu mō te "tipu ā muri ake nei." Tekau mā waru marama i muri mai, kua tae noa te whakamahinga ki te 40% o te kaha o te pākahiko: kua puhoi ake te tipu o te waka i te mea i matapaetia, ko te tihi o te papa ko te 220 kW, ā, he papaku te huringa o te pākahiko nui rawa atu - te momo mahi iti rawa te hua mō te rokiroki. Ko te mea kino rawa atu, i te pakaru o te inverter kotahi, i pōuri te papa utu katoa mō ngā rā e rima i te wā e tukuna ana he whakakapinga mai i tāwāhi.

E toru ngā take e kore ai e angitu ngā kaiwhakahaere i te huarahi kotahi: te wā whakapaipai (te utu i tēnei rā mō te kaha e whakamahia ana i roto i ngā tau e toru), te radius pahūtanga rahunga (ka hinga te rawa katoa i ngā pūwāhi rahunga kotahi), me te urutau (kāore e taea e te hoahoa pumau te neke ina huri ngā huarahi waka, ngā tahora papa rānei). Koinei tonu ngā momo rahunga e whakakorea ana e te hoahoa modular, koia te take i noho ai te BESS modular hei hoahoa taunoa i roto i te wāhanga arumoni me te ahumahi, ā, he aha te take e whakaarohia ana e te nuinga o ngā hoahoa tohutoro e whakaputaina ana e ngā kaiwhakahaere whatunga me ngā kaiwhakakotahi he poraka hanga modular, paerewa.

He aha te tikanga o te Modularity i roto i te BESS

E rua ngā taumata o te whakarerekētanga o te utu hiko BESS-integrated EV: te ara hiko me te ara pūngao. Kei roto i te ara hiko ngā waeine whakawhiti hiko paerewa rua-ara — mō MIDA, ngā waeine i roto i te [akomanga 20–40 kW](https://www.midapower.com/ev-charging-power-module) e huri ana i te whatunga AC ki te DC mō te pākahiko me te rihi, me ngā momo wai-whakamatao tae atu ki te 125 kW mō ngā tono mana-teitei. Kei roto i te ara pūngao ngā poraka pākahiko paerewa, ko te tikanga he 20–100 kWh ia, i hangaia mai i ngā pūtau LFP whaimana me te BMS whakauru me te whakahaere wera.

He motuhake ia poraka: ko ōna ake BMS, ko ōna ake hononga whakamatao, me ngā atanga miihini me te hiko paerewa. Ka honoa ngā poraka i roto i te raupapa me te whakarara kia tae atu ki te ngaohiko me te kaha e hiahiatia ana. Koinei te mea e wehewehe ana i te āhua tūturu mai i tētahi wāhanga noa iho: ka taea te whakawhiti, te tiaki, te whakakapi rānei i tētahi poraka me te kore e pā ki ētahi atu, ā, ka whirihora aunoa te kaiwhakahaere pūnaha ki te maha o ngā poraka hou. Mā te kaiwhakahaere e whakanui ana i te 240 kWh ki te 482 kWh ka tāpiri noa i tētahi atu poraka paerewa, ka hono atu ki te pahi DC, ā, ka taea te EMS te arotau anō - kāore he hoahoa anō, kāore he whakaritenga anō o te pae, kāore he wā whakatā roa.

Modular vs. Monolithic: He Whakataurite Taha-ki-Taha

E whakaata ana te ripanga whakatairite i ngā kōrero a ngā kaiwhakahaere i roto i te mahi: ka toa ngā pūnaha monolithic anake mēnā he tino pumau te āhua kawenga o te papa mō te roanga katoa o te oranga o te rawa — he āhuatanga onge i roto i te mākete utu e huri haere ana te tatau o ngā waka, ngā taumata hiko, me ngā hanganga taripa i roto i te pae tau e rima.

Te Whakarahi me te Kore e Hanga Nui: Te Whakarahi Tika me ngā Poraka Paerewa

Ko te rahi tika te whakatau pūtea nui rawa atu i roto i tētahi kaupapa rokiroki, ā, mā te āhua rerekē ka taea te huri. Ko te ture hangarau mō te utu hiko EV ko te rahi i te rokiroki ki te 0.5–1× te kaha utu teitei o te papa i roto i ngā kilowatt-hāora: ko te papa 120 kW e hiahia ana ki te 120–240 kWh; ko te papa 320 kW e hiahia ana ki te 240–480 kWh. Mā te [whānau hua rerekē](https://www.midapower.com/energy-storage-charging-station) ka taea e te kaiwhakahaere te hoko i te rohe o raro i te tuatahi, ā, ka whakawhānui ake ina tika ana ngā raraunga whakamahinga.

He whānau kōwae kotahi ngā whirihoranga katoa, nō reira, mā te kaiwhakahaere e whakahaere ana i ngā pae e rima i ngā tauine rerekē ka pupuri i tētahi kōwae hiko tāpiri me tētahi poraka pākahiko tāpiri mō te whatunga katoa. Ko te whakawhānui i waenga i ngā whirihoranga he whirihoranga anō i te taumata pae — te tāpiri poraka me te whakataurite anō i te EMS — ehara i te hoko hou.

Rautaki Tiaki, Tauwhiro, me ngā Wāhanga-Tāpiri

Ko te wātea te wāhi e mau tonu ai te mahi a te momohiko. I roto i te hoahoa hiko momohiko, ka whakamahia e te kaiwhakahaere teihana te taurite N+1: ko te whakaritenga poraka hiko 6×40 kW e mahi ana i te kawenga 240 kW ka manawanui ki te rahunga o tetahi momohiko kotahi me te kore e whakaiti i te kaha o te papa, ā, ko te rahunga tuarua ka whakaiti noa i te kaha. He rite tonu te mahi a ngā poraka pākahiko - ka wehea e te BMS te poraka rahunga, ā, ka haere tonu ngā poraka e toe ana ki te mahi ki te pahi DC.

Kātahi ka hurihia e te tiaki whakawhiti-wera taua mahi auau hei whakaora tere. Nā te mea he atanga paerewa ngā poraka, ka whakakapia e te tohunga hangarau tētahi waeine pakaru i raro i te haora mā te whakamahi i ngā taputapu ā-ringa, kaua ki te whakatikatika wheketere maha-rā mō tētahi waeine kotahi kua whakauruhia. Ka whakaitihia e tēnei te roa o te wā whakatika mai i ngā rā ki ngā hāora, ka hiki ake i ngā taurangi wātea o te waka, ā, ka whakaitihia te rarangi wāhanga tāpui ki tētahi huinga iti o ngā waeine whakawhiti e tohaina ana puta noa i te whatunga. Mō ngā kaiwhakahaere he whakaaetanga taumata-ratonga mō te utu huarahi - kei reira ia haora tuimotu ka ngaro te moni whiwhi me te ngaronga o te whakawhirinaki o ngā taraiwa - koinei te rerekētanga i waenga i te rawa ka taea te mahi me te nama.

Ngāwari o te Whakatakotoranga: Kotahi te Hanganga, He maha ngā Hōputu

Ka wehea hoki e te momotu te taputapu hiko mai i tōna whakatakotoranga ā-tinana. Ka whakanohoia te pākahiko me ngā poraka hiko kotahi ki roto i ngā anga e toru: ngā kāpata tū-papa mō ngā wāhi pumau, ngā papa nekeneke mō ngā whakatinanatanga rangitahi, ā-whatumanawa rānei, me ngā ipu whakauru-rā e whāngai tika ana te urunga PV ki te pahi DC.

Mā tēnei ngāwari o te whakatakotoranga ka taea e ngā kaiwhakahaere te whakatū anō i ngā rawa ina huri ngā āhuatanga pakihi. Ko te waeine rokiroki pūkoro 200 kWh e whakamahia ana hei uhi i tētahi wā raumati ka noho hei ārai tūmau mō te tau e whai ake nei; ka nekehia tētahi teihana kua nekehia e te whakarerekētanga o te huarahi ki te wāhi hou, kaua e whakakorea. Ko ngā whirihoranga whakauru-rā — pērā i te rihi hiko pūkoro 200 kWh/120 kW a MIDA me te whakaurunga rā MPPT — ka taea e ngā poraka waeine kotahi te mahi ki ngā wāhi he ngoikore, he kore rānei ngā hononga whatunga, ka huri i tētahi hoko rokiroki hei whakahohe motuhake-whatunga.

Me pēhea te whiriwhiri i te hoahoanga modular tika

Ko te whiriwhiri i tētahi BESS modular mō te utu EV ka whakaitihia ki te ono ngā whakatau, kia rite ki:

1. Tautuhia te papa me te tuanui mō ngā marama 24.Hokona he wāhi rokiroki mō te papa; whakamaherehia he poraka tāpiri mō te tuanui. 2.Whakapūmautia te rahi poraka kotahi puta noa i te whatungakia nui ake ai te whakawhitiwhiti i ngā taputapu tāpiri me ngā taputapu whakangungu. 3.Manatokohia te whanonga whakawhiti-wera me te N+1 i roto i te hoahoa pūnaha— whakaū i te taurite aunoa o te kaiwhakahaere ina tāpirihia, ina tangohia rānei ngā poraka. 4.Whakaūtia te ōritetanga o te whānau o ngā waeine hiko ki ngā taumata hiko o te rihinō reira, ka whai hua te pahi DC ki te whakamahi i te pākahiko me ngā waka (92–95% te haere hoki-mai). 5.Tirohia te tautoko kawa (OCPP, ISO 15118, Modbus) i runga i te waeine turanga, nā te mea me toro atu te rerekētanga o te taputapu ki te whirihoranga pūmanawa. 6.Kōwhiria he kaiwhakarato e horapa ana tōna whānau kōwae ki tō whānuitanga ūnga— mai i te whakairinga ki te pakitara ki te tauine huarahi — nō reira, kāore te tipu e akiaki i te whakawhiti kaihoko.

Ehara te whakarerekētanga i te āhuatanga; he rautaki whakahaere. Ka hurihia te rokiroki mai i tētahi petipeti pumau, rahi rawa ki tētahi putea o ngā poraka paerewa e tauine ana me ngā taunakitanga, e rahua ana, ā, e neke ana ki hea te pakihi e haere ana. Mō ngā kaiwhakahaere e whakamahere ana i ngā whatunga utu rima tau i roto i tētahi mākete tere haere, koinei te whakamāramatanga o te ngāwari - ā, ko te take i noho ai te BESS whakarerekētanga hei mea taunoa mō te umanga.
