He mea nui ngā rihi hiko DC/DC i roto i ngā pūnaha hiko o ēnei rā, inā koa i roto i ngā waka, i ngā pūnaha hiko o te rā, me ngā tono kore-pūnaha. Ko tētahi pātai noa i waenga i ngā kaiwhakamahi ko te mea ka taea e te rihi hiko DC/DC te utu i ngā pākahiko e rua i te wā kotahi. Ko te whakautu koāe, engari me ngā whakaaro nui e pā ana ki ngā waea, ngā momo pākahiko, me ngā kōtaha utu.
Ka tūhuratia e tēnei tuhinga te mahi a ngā rihi DC/DC me ngā pūnaha pākahiko-rua, ngā whirihoranga rerekē e wātea ana, me ngā tikanga pai mō te utu haumaru i ngā pākahiko e rua mai i tētahi rihi DC/DC kotahi.
Te Mārama ki ngā Taura DC/DC
I mua i te ruku ki te whakahōtaka pākahiko-rua, he mea nui kia mārama koe ki te mahi a te whakahōtaka pākahiko DC/DC:
- Ka Tahuri i te NgaohikoKa tangohia he tāuru DC (hei tauira, 12V mai i te waka) ka whakatikatika ki te putanga e hiahiatia ana (hei tauira, 12V, 24V rānei mō te pākahiko tuarua).
- Whakahaere i te Utu: Ka whakarite i te tika o te kōtaha utu (papatipu, mimiti, pōrewarewa) mō te momo pākahiko (waikawa-mata, lithium, AGM, me ētahi atu).
- Ārai i te Utu Nui: Ka tiaki i ngā pākahiko mai i te ngaohiko nui rawa, ka taea ai te whakapoto i te roa o te ora.
He rerekē te rihi hiko DC/DC i te kaitahuri ngaohiko noa iho nā te mea ka whakahaere kaha ia i te tukanga utu, kaua ki te whakarite noa i te ngaohiko.
Ka taea e te rihi DC/DC kotahi te utu i ngā pākahiko e rua?
Ae, engari e rua ngā huarahi matua hei mahi i tēnei:
- Te Utu Whakarara– Te hono i ngā pākahiko e rua i te taha whakarara ki tētahi rihi DC/DC kotahi.
- Ngā Kaitautoko DC/DC Putanga-Rua– Te whakamahi i tētahi rihi i hangaia mō ngā pākahiko e rua.
He painga, he ngoikoretanga hoki tō ia tikanga.
Tikanga 1: Te Utu Whakarara (Utu Putanga Kotahi DC/DC)
Ki te honoa e koe ngā pākahiko e rua i te taha o tētahi rihi DC/DC kotahi, ka utua ngātahi rāua. Heoi, he mea nui ngā whakaaro mō tēnei tatūnga:
Ngā Painga o te Utu Whakarara
✔Waea Māmā Ake– Kotahi noa te rihi e hiahiatia ana.
✔Whai hua te utu– Kāore e hiahiatia he rihi putanga-rua.
✔Ngaohiko Taurite– ...
Ngā Huakore o te Utu Whakarara
❌Te Utu Kāore i te Taurite– Mena he rerekē ngā āhua utu (SoC) o ngā pākahiko, ka tere ake pea te utu o tētahi i tētahi.
❌Ngā Momo Pūhiko Whakaranu– Tērā pea ka hiahiatia he rerekē ngā āhua utu mō ngā matū rerekē (hei tauira, te lithium + te waikawa mata).
❌Te taumaha rawa pea– Me whakahaere e te rihi hiko DC/DC te tono iahiko whakakotahi.
Ngā Tikanga Pai mō te Utu Whakarara
- Whakamahiangā pākahiko ōrite(he rite tonu te kaha, te tau, me te matū).
- Me whakarite kia rawaka te rihi DC/DCte kaha o nāianei(hei tauira, ka taea e te rihi hiko 30A te whakahaere i ngā pākahiko 100Ah e rua, engari ka puhoi pea te utu).
- Whakaarohia hewehewehe pākahikorāneite whakawhiti hiko-tairongo (VSR)mēnā he pākahiko tīmata tētahi pākahiko.
Tikanga 2: Ngā Pūrere Whakarewa DC/DC Putanga-Rua
Kua hangaia ētahi rihi DC/DC mee rua ngā putanga motuhake, e āhei ai rātou ki te utu motuhake i ngā pākahiko e rua.
Te Mahi a ngā Rīhi DC/DC Putanga-Rua
- Ngā Kōtaha Utu Motuhake– Ka taea te whakarite i ia putanga mō ngā momo pākahiko rerekē (hei tauira, te lithium mō tētahi, te AGM mō tētahi).
- Whakahaere Utaina Atamai– Ko ētahi tauira e whakatau ana i te utunga i runga i ngā hiahia o te pākahiko.
- Ngā Arahiko Motuhake– Ārai i te paunga o te pākahiko o tētahi atu.
Ngā Tauira o ngā Pūrere Whakarewa DC/DC Putanga-Rua
- Redarc BCDC1240D– Ka utua ngā pākahiko e rua me te mana whakahaere motuhake.
- Victron Orion-Tr Atamai– Ka taea te whirihora mō te utu pākahiko takirua.
- Kisae DMT1250– E tautoko ana i ngā pākahiko e rua me ngā matū rerekē.
Ngā Painga o ngā Rīhi Putanga-Rua
✔Te Utu Arotau– Ka whiwhi ia pākahiko i te ngaohiko me te iahiko tika.
✔Tautoko i ngā Momo Pūhiko Whakaranu– He pai mō ngā pūnaha he pākahiko tīmatanga me he pākahiko wātea.
✔He Pai Ake– Ka whakaiti i te moumou pūngao ki te whakataurite ki ngā whakatakotoranga whakarara.
Ngā Huakore o ngā Rihi Putanga-Rua
❌Te utu teitei ake– He nui ake te utu i ngā rihi putanga-kotahi.
❌Tāutanga Uaua– Me whai waea me te whirihoranga tika.
Kōwhiringa kē: Te whakamahi i te Pūhiko Whakawehe, VSR rānei
Mena kāore āu rihi hiko DC/DC putanga-rua, ko tētahi atu kōwhiringa ko te whakamahi i:
- Relay Tairongo-Ngaohiko (VSR)– Ka hono/momotu aunoa i ngā pākahiko i runga i te ngaohiko.
- Pātene Pūhiko ā-ringa– Mā tēnei ka taea e koe te whiriwhiri ko tēhea pākahiko hei utu.
- Kaiwhakawehe i runga i te Diode– Ka ārai i te rere whakamuri engari ka heke te ngaohiko.
Mā ēnei tikanga ka taea te utu i ngā pākahiko e rua mai i te pūtake DC kotahi (hei tauira, he alternator, he papa rā rānei) engari kāore e whakakapi i te whakahaere atamai o te rihi DC/DC.
Ngā Whakaaro Matua mō te Whakautu i ngā Pūhiko e Rua
1. Hototahi ki te Matū Pūhiko
- Waikawa-Mata (AGM, Kirikiri, Waipuke)– Me whai āhua utu maha-wāhanga.
- Ritiumu (LiFePO4)– Me whakahaere tika te ngaohiko.
- Ngā Pūnaha Whakaranu– Me whakamahi noa me te rihi putanga-rua.
2. Te kaha o te rihi
- Tērā pea ka raru tētahi rihi hiko 20A DC/DC i ngā pākahiko nunui e rua.
- Mō te utu tere ake, whakamahia he rihi utu he nui ake te amperage (hei tauira, 40A+).
3. Te Waea me te Hononga
- Whakamahia ngā taura matotoru hei whakahaere i te iahiko whakakotahi.
- Tāutahia ngā fiusi tata ki ia pākahiko hei haumaru.
4. Te Aroturuki
- Whakamahia he aroturuki pākahiko (hei tauira, Victron BMV) hei aroturuki i te tūnga utu.
Ngā Whakamahinga Whai Hua
1. Pūhiko Takirua 4×4 me ngā Kapene
- Pūhiko Tīmata– Ka whakakaha i te waka.
- Pūhiko Āwhina– E whakahaere ana i ngā pouaka whakamātao, ngā rama, me ngā pūwhakakā hiko.
- Mā te rihi DC/DC ka whakarite kia tika te utu o te pākahiko āwhina mai i te alternator.
2. Ngā Pūnaha Hiko o te Rā
- Peeke Pūhiko Whare– E penapena ana i te pūngao o te rā.
- Pūrua Pūhiko Tīmata– Ka taea te whakakī ake mā te whakamahi i tētahi rihi putanga-rua.
3. Ngā Pūnaha Moana me te RV
- Pūhiko Mīhini– Hei tīmatanga.
- Peeke Whare– Mō ngā taputapu.
- Ka āraihia e te rihi DC/DC te paunga o te pākahiko tīmatanga e te kawenga whare.
Whakamutunga: Ae, Engari Kōwhiria te Tikanga Tika
He rihi DC/DCkēneutua kia rua ngā pākahiko, engari ko te tikanga pai rawa atu kei tō tautuhinga:
✅Mō ngā pākahiko ōrite→ Ka mahi te utu whakarara (engari me aroturuki tonu).
✅Mō ngā momo pākahiko whakauru→ Whakamahia herihi DC/DC putanga-rua.
✅Mō ngā whakaritenga māmā→ Ka taea e te VSR, te whakawehe rānei te āwhina, engari kāore i te wātea te utu atamai.
Mena kei te hiahia koe ki te utu pono, whai hua hoki mō ngā pākahiko e rua, me haumi koe ki tētahirihi DC/DC putanga-ruakoinei te otinga pai rawa atu mō te wā roa.
