Me pēhea te mahi a ngā pūnaha rokiroki pūngao pākahiko?

Ko te pūnaha rokiroki pūngao pākahiko, e mōhiotia whānuitia ana ko te BESS, e whakamahi ana i ngā pēke pākahiko ka taea te whakahou hei penapena i te hiko nui mai i te whatunga hiko, i ngā pūtake whakahou rānei mō te whakamahinga a muri ake nei. I te whanaketanga haere o te pūngao whakahou me ngā hangarau whatunga atamai, kei te piki haere te mahi nui a ngā pūnaha BESS ki te whakaū i ngā pūtake hiko me te whakanui ake i te uara o te pūngao matomato. Nō reira, me pēhea te mahi a ēnei pūnaha?
Hipanga 1: Pēke Pūhiko
Ko te pūtake o tētahi BESS ko te reo rokiroki pūngao - arā, ko ngā pākahiko. He maha ngā wae pākahiko, arā, ngā "pūtau" ka honoa ngātahitia hei hanga i tētahi "pēke pākahiko" e whakarato ana i te kaha rokiroki e hiahiatia ana. Ko ngā pūtau e whakamahia whānuitia ana ko te lithium-ion nā te mea he nui te kaha o te mana, he roa te ora, ā, he tere hoki te utu. Ko ētahi atu matū pēnei i te waikawa-mata me ngā pākahiko rere ka whakamahia hoki i roto i ētahi mahi.
Hipanga 2: Pūnaha Tahuri Mana
Ka hono te pēke pākahiko ki te whatunga hiko mā te pūnaha whakawhiti hiko, PCS rānei. Kei roto i te PCS ngā wāhanga hikohiko pēnei i te inverter, te kaitahuri, me ngā tātari e tuku ana i te hiko kia rere i ngā taha e rua i waenga i te pākahiko me te whatunga hiko. Ka hurihia e te inverter te iahiko tika (DC) mai i te pākahiko ki te iahiko tauutuutu (AC) e whakamahia ana e te whatunga hiko, ā, ka mahi te kaitahuri i te ritenga kē hei utu i te pākahiko.
Hipanga 3: Pūnaha Whakahaere Pūhiko
Ka aroturukihia, ka whakahaerea hoki e te pūnaha whakahaere pākahiko, te BMS rānei, ia pūtau pākahiko takitahi i roto i te pēke pākahiko. Ka whakatauritehia e te BMS ngā pūtau, ka whakahaere i te ngaohiko me te iahiko i te wā utu me te tukunga, ā, ka tiaki i te kino mai i te utu nui rawa, te iahiko nui rawa, te tukunga hohonu rānei. Ka aroturukihia e ia ngā tawhā matua pēnei i te ngaohiko, te iahiko me te pāmahana hei whakapai ake i te mahi me te roa o te pākahiko.
Hipanga 4: Pūnaha Whakamatao
Ka tangohia e te pūnaha whakamatao te wera nui mai i ngā pākahiko i te wā e whakahaerehia ana. He mea nui tēnei kia mau tonu ngā pūtau i roto i tō rātou awhe pāmahana tino pai, kia roa ai hoki te ora o te huringa. Ko ngā momo whakamatao e whakamahia whānuitia ana ko te whakamatao wai (mā te huri i te whakamatao mā roto i ngā pereti e pā ana ki ngā pākahiko) me te whakamatao hau (mā te whakamahi i ngā pā hau hei pana i te hau mā roto i ngā pouaka pākahiko).
Hipanga 5: Te Mahi
I ngā wā e iti ana te hiahia hiko, e nui ana rānei te whakaputanga pūngao whakahou, ka mimiti te BESS i te kaha nui mā te pūnaha whakawhiti hiko, ā, ka rongoatia ki roto i te pēke pākahiko. Ina nui te hiahia, ina kore rānei e wātea ngā pūngao whakahou, ka tukuna te pūngao kua rongoatia ki te whatunga hiko mā te inverter. Mā tēnei ka taea e te BESS te "neke wā" i te pūngao whakahou wā-poto, te whakaū i te auau me te ngaohiko o te whatunga hiko, me te whakarato hiko tārua i ngā wā motumotu.
Ka aroturukihia e te pūnaha whakahaere pākahiko te āhua o te utu o ia pūtau, ā, ka whakahaeretia hoki te tere o te utu me te tukunga hei ārai i te utu nui rawa, te wera rawa me te tukunga hōhonu o ngā pākahiko - kia roa ake ai te ora o ā rātou mahi. Ā, ka mahi te pūnaha whakamatao hei pupuri i te pāmahana pākahiko whānui i roto i te awhe mahi haumaru.
Hei whakarāpopototanga, ka whakamahia e te pūnaha rokiroki pūngao pākahiko ngā pākahiko, ngā wāhanga hikohiko mana, ngā mana whakahaere atamai me te whakahaere wera i roto i te huarahi whakauru hei penapena i te hiko taikaha me te tuku hiko ina hiahiatia. Mā tēnei ka taea e te hangarau BESS te whakanui ake i te uara o ngā pūtake pūngao whakahou, te whakapai ake i te whai hua me te pumau o ngā whatunga hiko, me te tautoko i te whakawhiti ki te heke mai o te pūngao iti-waro.

I te pikinga ake o ngā pūtake pūngao hou pērā i te hiko o te rā me te hau, kei te piki haere te hiranga o ngā pūnaha rokiroki pūngao pākahiko nui (BESS) ki te whakau i ngā whatunga hiko. Ka whakamahia e te pūnaha rokiroki pūngao pākahiko ngā pākahiko ka taea te whakahou hei penapena i te hiko nui mai i te whatunga hiko, mai i ngā pūngao hou rānei, ā, ka whakahokia mai taua hiko ina hiahiatia. Ka āwhina te hangarau BESS ki te whakanui ake i te whakamahinga o te pūngao hou ā-wā, ā, ka whakapai ake i te pono, te whai huatanga me te pumau o te whatunga hiko.
He maha ngā wāhanga o te BESS:
1) He pēke pākahiko i hangaia mai i ngā kōwae pākahiko maha, i ngā pūtau rānei hei whakarato i te kaha rokiroki pūngao e hiahiatia ana. Ko ngā pākahiko lithium-ion te mea e whakamahia whānuitia ana nā te mea he nui te kaha o te mana, he roa te ora, ā, he tere hoki te utu. Ka whakamahia hoki ētahi atu matū pēnei i te waikawa mata me ngā pākahiko rere.
2) Pūnaha whakawhiti hiko (PCS) e hono ana i te pēke pākahiko ki te whatunga hiko. Kei roto i te PCS he kaitahuri hiko, he kaitahuri hiko me ētahi atu taputapu whakahaere e taea ai te rere o te hiko i ngā taha e rua i waenga i te pākahiko me te whatunga hiko.
3) Pūnaha whakahaere pākahiko (BMS) e aroturuki ana, e whakahaere ana hoki i te āhua me te mahi a ngā pūtau pākahiko takitahi. Ka whakataurite te BMS i ngā pūtau, ka tiaki i a rātou mai i te kino mai i te utu nui rawa, te tukunga hohonu rānei, ā, ka aroturuki hoki i ngā tawhā pēnei i te ngaohiko, te iahiko me te pāmahana.
