Ko te Pūnaha Rokiroki Pūngao Pūhiko (BESS) he pūnaha pākahiko tauine nui e hangai ana ki te hononga whatunga, e whakamahia ana hei rokiroki hiko me te pūngao. Ka whakakotahi i ngā pākahiko maha hei hanga i tētahi taputapu rokiroki pūngao kua whakauruhia.
1. Pūtau Pūhiko: Hei wāhanga o te pūnaha pūhiko, ka hurihia e ia te pūngao matū hei pūngao hiko.
2. Wāhanga Pūhiko: He mea tito mai i ngā pūtau pūhiko maha e hono ana i ngā raupapa me ngā pūtau pūhiko whakarara, kei roto ko te Pūnaha Whakahaere Pūhiko Wāhanga (MBMS) hei aroturuki i te mahi a ngā pūtau pūhiko.
3. Pūtau Pūhiko: Whakamahia hei whakauru i ngā kōwae maha e hono ana i te raupapa me ngā Wāhanga Tiaki Pūhiko (BPU), e mōhiotia ana ko te kaiwhakahaere pūtau pūhiko. Ka aroturukihia e te Pūnaha Whakahaere Pūhiko (BMS) mō te pūtau pūhiko te ngaohiko, te pāmahana, me te tūnga utu o ngā pūhiko me te whakahaere i ā rātou huringa utu me te tuku.
4. Ipu Rokiroki Pūngao: Ka taea te kawe i ngā tautau pākahiko maha e hono ana whakarara ana, ā, ka taea te whakauru atu ki ētahi atu wāhanga hei whakahaere, hei whakahaere rānei i te taiao o roto o te ipu.
5. Pūnaha Whakawhiti Hiko (PCS): Ka hurihia te iahiko tika (DC) e hangaia ana e ngā pākahiko hei iahiko whakawhiti (AC) mā roto i ngā PCS, i ngā kaitahuri rua-ara rānei hei tuku ki te whatunga hiko (ngā whare, ngā kaiwhakamahi mutunga rānei). Mēnā e tika ana, ka taea hoki e tēnei pūnaha te tango hiko mai i te whatunga hiko hei utu i ngā pākahiko.
He aha te mātāpono mahi o ngā Pūnaha Rokiroki Pūngao Pūhiko (BESS)?
Ko te mātāpono mahi o te Pūnaha Rokiroki Pūngao Pūhiko (BESS) e toru ngā tukanga matua: te utu, te penapena, me te tuku hiko. I te wā o te utu, ka rongoa e BESS te pūngao hiko i roto i te pākahiko mā te pūtake hiko o waho. Ka taea te whakatinanatanga mā te au tika, mā te au hurihuri rānei, i runga i te hoahoa pūnaha me ngā whakaritenga tono. Ina he nui te mana e whakaratohia ana e te pūtake hiko o waho, ka hurihia e BESS te pūngao taikaha hei pūngao matū, ā, ka rongoatia ki roto i ngā pākahiko ka taea te utu anō i roto i te āhua whakahou i roto. I te wā o te rokiroki, ina kore he rawaka, kāore rānei he puna hiko o waho e wātea ana, ka pupuri a BESS i te pūngao kua rongoatia kua utua katoatia, ā, ka mau tonu tōna pumau mō te whakamahinga a meake nei. I te wā o te tuku hiko, ina hiahiatia te whakamahi i te pūngao kua rongoatia, ka tukuna e BESS te nui o te pūngao e tika ana kia rite ki te hiahia mō te taraiwa i ngā taputapu, ngā miihini, ngā momo kawenga rānei.
He aha ngā painga me ngā wero o te whakamahi i te BESS?
Ka taea e BESS te whakarato i ngā painga me ngā ratonga maha ki te pūnaha hiko, pēnei i:
1. Te whakapakari ake i te whakaurunga o te pūngao whakahou: Ka taea e BESS te penapena i te pūngao whakahou nui i ngā wā whakaputa nui me te iti o te tono, ka tukuna atu i ngā wā whakaputa iti me te nui o te tono. Ka taea e tēnei te whakaiti i te aukati hau, te whakapai ake i tōna tere whakamahinga, me te whakakore i tōna wā whakaroa me te rerekētanga.
2. Te whakapai ake i te kounga me te pono o te hiko: Ka taea e BESS te whakarato urupare tere me te ngāwari ki ngā piki me ngā heke o te ngaohiko me te auau, ngā harmonics, me ētahi atu take kounga hiko. Ka taea hoki te mahi hei puna hiko tārua me te tautoko i te mahi tīmatanga mangu i te wā e motu ana te whatunga hiko, i ngā āhuatanga ohorere rānei.
3. Te whakaiti i te hiahia nui: Ka taea e BESS te utu i ngā wā kore-pīki ina iti ngā utu hiko, ā, ka taea te tuku i te hiko i ngā wā pīki ina teitei ngā utu. Ka taea e tēnei te whakaiti i te hiahia nui, te whakaiti i ngā utu hiko, me te whakaroa i te hiahia mō te whakawhānui i te kaha o te whakatipuranga hou, te whakapai ake rānei i te tuku hiko.
4. Te whakaiti i ngā tukunga hau kati kōtuhi: Ka taea e te BESS te whakaiti i te whakawhirinaki ki te whakaputanga wahie pūmua, inā koa i ngā wā tino pukumahi, me te whakanui ake i te wāhi o te pūngao whakahou i roto i te ranunga hiko. Ka āwhina tēnei ki te whakaiti i ngā tukunga hau kati kōtuhi me te whakaiti i ngā pānga o te huringa āhuarangi.
Heoi anō, kei te pā mai anō hoki ētahi wero ki a BESS, pēnei i:
1. Te utu nui: Ki te whakatauritea ki ētahi atu puna hiko, he tino utu nui tonu te BESS, inā koa mō ngā utu whakapaipai, ngā utu whakahaere me te tiaki, me ngā utu huringa ora. Ko te utu o te BESS e whakawhirinaki ana ki ngā āhuatanga maha pēnei i te momo pākahiko, te rahi o te pūnaha, te tono, me ngā āhuatanga o te mākete. I te pakeketanga me te whānui haere o te hangarau, e matapaetia ana ka heke te utu o te BESS a muri ake nei engari tera pea ka waiho hei arai ki te whakamahinga whānui.
2. Ngā take haumaru: Kei roto i te BESS ngā ngaohiko teitei, te iahiko nui, me te pāmahana teitei e tūpono ana ki ngā mōrearea pēnei i te ahi, te pahūtanga, te ru hiko me ētahi atu. Kei roto hoki i te BESS ngā matū morearea pēnei i te konganuku, te waikawa me ngā electrolytes ka pā he mōrearea ki te taiao me te hauora mena kāore e whakahaerea, e makahia rānei i te huarahi tika. Me whai paerewa haumaru, ture me ngā tikanga tino pakari hei whakarite i te whakahaere haumaru me te whakahaere o te BESS.
5. Pānga ki te taiao: Tērā pea ka pā kino a BESS ki te taiao tae atu ki te whakaiti i ngā rauemi, ngā take whakamahinga whenua, ngā raruraru whakamahinga wai, te whakaputanga para, me ngā āwangawanga parahanga. He nui ngā rauemi mata e hiahiatia ana e BESS pērā i te lithium, te cobalt, te nickel, te parahi me ētahi atu, he onge noa iho i te ao katoa, ā, kāore i te ōrite te tohatoha. Ka pau hoki i a BESS te wai me te whenua mō ngā mahi keri me te whakahaere. Ka puta he para me ngā tukunga a BESS puta noa i tōna huringa ora, ka pā pea ki te kounga o te hau, te wai, te oneone. Me whai whakaaro ki ngā pānga ki te taiao mā te whakamahi i ngā tikanga pumau hei whakaiti i ō rātou pānga i te mea ka taea.
He aha ngā whakamahinga matua o BESS me ōna āhuatanga?
He whānuitia te whakamahinga o te BESS i roto i ngā ahumahi me ngā tono maha, pērā i te whakaputa hiko, ngā whare rokiroki hiko, ngā raina tuku me te tohatoha i roto i te pūnaha hiko, tae atu ki ngā pūnaha waka hiko me te moana i roto i te rāngai kawe waka. Ka whakamahia hoki i roto i ngā pūnaha rokiroki hiko pākahiko mō ngā whare noho me ngā whare arumoni. Ka taea e ēnei pūnaha te whakatutuki i ngā hiahia rokiroki o te hiko tāpiri me te whakarato i te kaha tārua hei whakaiti i te taumaha i runga i ngā raina tuku me te tohatoha me te ārai i te whakakīkī i roto i te pūnaha tuku. He mahi nui tā te BESS i roto i ngā whatunga hiko iti, arā, he whatunga hiko tohatoha e hono ana ki te whatunga matua, e mahi motuhake ana rānei. Ka taea e ngā whatunga hiko iti motuhake kei ngā wāhi tawhiti te whakawhirinaki ki te BESS me ngā puna hiko whakahou kia tutuki ai te whakaputa hiko pumau me te āwhina ki te karo i ngā utu nui e pā ana ki ngā miihini tīhiera me ngā take parahanga hau. He maha ngā rahi me ngā whirihoranga o te BESS, e tika ana mō ngā taputapu whare iti me ngā pūnaha whaipainga nui. Ka taea te tāuta ki ngā wāhi rerekē tae atu ki ngā kāinga, ngā whare arumoni, me ngā teihana hiko iti. Hei tāpiri, ka taea e rātou te mahi hei puna hiko tārua ohorere i te wā e motu ana te hiko.
He aha ngā momo pākahiko e whakamahia ana i roto i te BESS?
1. Ko ngā pākahiko waikawa-mata te momo pākahiko e whakamahia whānuitia ana, he mea tito mai i ngā pereti mata me te electrolyte waikawa whanariki. E tino whakanuia ana ēnei mō te iti o te utu, te hangarau pakari, me te roa o te ora, e whakamahia ana i ngā wāhi pēnei i te tīmatanga o ngā pākahiko, ngā pūtake hiko ohorere, me te rokiroki hiko iti.
2. Ko ngā pākahiko lithium-ion, tētahi o ngā momo pākahiko rongonui me te matatau, he mea hanga mai i ngā irahiko pai me ngā irahiko kino i hangaia mai i te konganuku lithium, i ngā rauemi hiato rānei, me ngā whakarewa waro. He painga ō rātou pēnei i te nui o te kaha, te pai o te mahi, me te iti o te pānga ki te taiao; he mea nui tēnei i roto i ngā taputapu pūkoro, ngā waka hiko, me ētahi atu tono rokiroki kaha.
3. He taputapu rokiroki hiko ka taea te whakahou ake ngā pākahiko rere e whakamahi ana i ngā rauemi wai e rongoa ana i roto i ngā tāke o waho. Ko ō rātou āhuatanga ko te iti o te kiato hiko engari he nui te whai huatanga me te roa o te ora mahi.
4. Haunga ēnei kōwhiringa kua whakahuatia i runga ake nei, kei reira anō ētahi atu momo BESS e wātea ana hei kōwhiringa pērā i ngā pākahiko konutai-whāwhā, ngā pākahiko nikara-kāmium, me ngā pūnga kaha; he rerekē ngā āhuatanga me ngā mahi o ia pākahiko e tika ana mō ngā āhuatanga rerekē.
