Nā tētahi miihini pākahiko lithium matua i tuhi tēnei tuhinga, e whakamārama ana i te tukanga matua mō te whakarite i tētahi kete pākahiko atamai mō ngā kaihoroi papa. Ko te angitu e whakawhirinaki ana ki tētahi huarahi pūnaha e whakataurite ana i te mahi, te haumaru, me te roa o te ora.
Ngā Whakaritenga Matua: Ka tīmata te tukanga me te māramatanga hōhonu ki ngā hiahia whakahaere o te kaihoroi, tae atu ki ngā whakatakotoranga mana o tōna motuka, ngā rahi o te wāhanga pākahiko, me te kawa whakawhitiwhiti kōrero e hiahiatia ana (hei tauira, CAN Bus).
Hei miihini pākahiko lithium matua, he wheako ki ngā rau kaupapa whakaritenga mō ngā kete pākahiko, i tēnei rā ka whakapuaki ahau i tētahi kaupapa mō te whakarite i tētahi kete pākahiko atamai mō tētahi kaihoroi papa. I hiahia te kiritaki ki tētahi kaihoroi papa atamai, nō reira me atamai anō hoki te kete pākahiko.
Tuatahi, me mārama tātou ki ngā āhuatanga whakahaere o te mīhini horoi papa me ōna hiahia mana motuhake.
Me whakarato mai e te kiritaki ngā tawhā matua ki a mātou, tae atu ki: ngā rahi o te wāhanga pākahiko, te ngaohiko whakatauranga o te motuka, te mana whakatauranga, te mana mōrahi, te iahiko whakauru i te wā tīmatanga, ngā atanga pito pai/kino, ngā pito atanga whakawhitiwhiti kōrero, me te roanga mahi noa mō ia huringa. Hei tāpiri, he mea nui te whakarato i te kawa whakawhitiwhiti kōrero a te kaihoroi papa. Mā ēnei tawhā, ka taea e tātou te tīmata i te hoahoa pākahiko.
Ngā Huānga Hangarau Matua i roto i te Whakaritenga Pūhiko Atamai
1. Kōwhiringa Pūtau: LiFePO4 vs. NMC
Ko te pūtau te uho o te pūnaha pākahiko, ā, me whai whakaaro ki ngā āhuatanga maha o te kōwhiringa:
Ngā Pūtau LiFePO4 (Lithium Iron Phosphate): He tino pai te pumau o te wera, he roa te ora o te huringa (neke atu i te 2000 huringa), ā, he tino haumaru. Ko ō rātou ngoikoretanga ko te iti o te kaha o te pūngao me te ngoikore o te mahi pāmahana iti, ahakoa ka taea te whakaiti i tēnei mā te whakauru i tētahi waeine whakamahana.
Ngā Pūtau NMC (Nickel Manganese Cobalt): He nui te kaha o te pūngao, ā, he pai ake te mahi pāmahana iti. Heoi, he ngoikore ake te pumau o te wera, ā, he nui ake ngā whakaritenga mō te Pūnaha Whakahaere Pūhiko (BMS).
Mō ngā mīhini horoi papa arumoni e whakamahia ana i ngā wāhi pumau, ka tino taunaki mātou i te otinga LiFePO4, nā te mea he mea nui te haumaru me te roa o te huringa.
2. Hoahoa Pūnaha Whakahaere Pūhiko Atamai (BMS)
Ko te BMS te "roro" o te pākahiko. Mō te pākahiko horoi papa atamai, kei roto i tā mātou hoahoa BMS ngā mahi e whai ake nei:
Aroturukitanga Tika: Te aro turuki i ngā tawhā ngaohiko, iahiko, me te pāmahana i te wā tūturu, me te inenga ngaohiko i roto i te ±1mV.
Hangarau Taurite Pūtau: Ka whakarite i te ōritetanga i waenga i ngā pūtau takitahi, ka roa ake te roa o te ora ratonga pākahiko. Ka tautokohia e tā mātou hoahoa BMS motuhake te Hōhonutanga o te Tukunga (DoD) tae atu ki te 95% me te kore e whakararu i te roa o te huringa, ka tutuki mā roto i ngā rauropi taurite matatau.
Ngā Tikanga Parenga Maha-Taumata: Parenga whānui mai i te utu nui rawa, te tukunga nui rawa, te iahiko nui rawa, te ara iahiko poto, me ngā pāmahana tino tiketike/iti.
Te Whakawhitiwhiti Kōrero me te Takiuru Raraunga: Ka tautoko i ngā kawa whakawhitiwhiti kōrero pēnei i te CAN Bus me te RS485. Ka tuhia ngā raraunga mahi o mua hei whakahaere i te tātari hapa me te arotau i te mahi.
3. Te Hoahoa Hanganga me te Āheitanga ki te Taiao
Me whai whakaaro te hoahoa hanganga o te pākahiko ki te taiao mahi tuturu:
Whakatauranga Parenga Whakauru (IP): E taunakihia ana kia iti rawa te whakatauranga IP65 hei ārai i te urunga mai o te makuku i te wā e horoia ana.
Hoahoa Whakahaere Wera: Te whiriwhiri i tētahi rautaki whakamatao tika (hei tauira, te whakamatao kore mahi, ngā rauemi whakarerekē-āhuatanga, te whakamatao hau kaha rānei) i runga i ngā whakaritenga o te tere tukunga (tere-C).
Hanganga Mīhini: Kei roto te ātete wiri me te hoahoa āhua rerekē hei ngāwari ake te tiaki me te whakakapi.
4. Te Whakaritenga o ngā Tawhā Hiko
Me tatau tika ngā tawhā hiko kia rite ki ngā hiahia mana motuhake o te kaihoroi:
Ngaohiko me te Pūmanawa: Ko te ngaohiko noa o tā mātou hoahoa paerewa he 25.6V me te pūmanawa 150Ah.
Te Āheinga Tukunga: Ka tukuna e te pākahiko he iahiko tukunga tonu mōrahi o te 150A, me te āheinga iahiko tukunga teitei o te 300A, e tutuki katoa ana i ngā whakaritenga uaua o te kaihoroi papa.
Ngā Mahanga Noa me ngā Whakaaro Matua
E ai ki ō mātou wheako hangarau, ko ngā whakaaro hē noa mō te whakaritenga pākahiko horoi papa ko:
Te Aro nui ki te Kaha Teitei: Te kore e aro ki te pikinga o te rahi me te taumaha, ka pā kino pea tēnei ki te ngāwari o te nekeneke me te ngāwari o te whakahaere.
Te Whakahāwea i te Hototahi o ngā Ripanga: Me whakamahi ngā pākahiko lithium i ngā rihi motuhake. Ka raru pea te ngoikore o ngā hiko utu kāore i te ōrite.
Huarahi Utu-Nui Rawa: Mā te whiriwhiri i ngā pūtau kounga-iti me te whakangāwari i ngā mahi BMS ka whakaiti i ngā utu tīmatanga engari he maha ngā wā ka poto ake te roa o te ora me te nui ake o ngā whakapaunga tiaki mō te wā roa.
