Hangarau Utu Tere me te Whakahaere Mahana Atamai
Nā te whanaketanga o te hangarau utu tere i ngā tau tata nei kua hurihia te huarahi e whakamahia ai e te tangata ngā taputapu hiko, inā koa ngā waea atamai, ngā pona, ngā taputapu mau, tae atu ki ngā waka hiko. Ahakoa i mua he maha ngā hāora e pau ana ki te utu i te pākahiko, he maha ngā taputapu ka taea te eke ki te tekau ōrau i roto i ngā meneti noa iho. Heoi, kei muri i tēnei whai wāhitanga he wero hangarau nui: te wera. Ko te nui ake o te hiko e tukuna ana ki te pākahiko, ko te nui ake o te tūponotanga o te pikinga o te pāmahana. Koinei te wāhi e whai wāhi nui ai te whakahaere wera atamai ki te whakarite kia tere tonu te utu tere, kia haumaru, kia ora ai te pākahiko.
He aha te take e whakaputa ai te wera i te utunga tere?
Ki te whakarapopoto, ko te tikanga o te utu tere ko te tuku i te hiko nui ake ki te pākahiko i roto i te wā poto ake. I te pikinga ake o te hiko kua whakawhitia, ka piki ake hoki te iahiko (amperes) me/ranei te ngaohiko (volts). I roto i tētahi pūnaha hiko, ka puta te wera mai i te ātete i roto i ngā raina utu, ngā hononga, ngā ara iahiko whakahaere hiko, me ngā pūtau pākahiko tonu. Ko te teitei ake o te iahiko, ko te nui ake o te kaha ki te whakamahana.
Haunga te ātete, he āhuatanga matū tō ngā pākahiko lithium—arā, te lithium-ion me te lithium-polymer—e pāngia ana e te pāmahana. Ina whiwhi te pūtau pākahiko i te iahiko teitei, ka tere ake te puta o ngā tauhohenga matū o roto, ka piki ake te pāmahana. Ehara i te mea ka wera noa te taputapu i ngā pāmahana tino teitei engari ka tere ake te pakaru o te pākahiko, ka whakaiti i te kaha, ā, ka piki ake ngā mōrearea haumaru mena kāore e whakahaerea tika.
Te Whanaketanga o te Utu Tere: Tere ake, Atamai ake
Kāore te utu tere o ēnei rā e pā ana ki te "whakanui ake i te mana" anake. Kei te whakawhanake ngā kaihanga i ngā kawa utu pēnei i te USB Power Delivery (USB PD), te Qualcomm Quick Charge, me ngā hangarau motuhake mai i ngā kaihanga taputapu. Ko te tikanga, ka kōrero te rihi me te taputapu hei whakatau i te huinga au-ngaohiko tino pai.
I ngā rā tōmua o te utu tere, he māmā ake te whakahaere: i tono te taputapu kia nui te hiko, kātahi ka whakaitihia i te tata ki te kī o te pākahiko. I ēnei rā, he tino uaua ake te pūnaha. Kua wehea te utu ki ētahi wāhanga, hei tauira:
1. Wāhanga tīmatanga (whakautu-mua/whakatikatika): ina iti te pākahiko, ka piki haere te iahiko.
2. Wāhanga tere (au pūmau): ka whakamahia te au teitei hei whakanui wawe i te kaha.
3. Wāhanga whakapūmau (ngaohiko pumau): ka mau tonu te ngaohiko, ka tīmata te heke o te iahiko.
4. Wāhanga katoa (whakakī-ake/maturuturu): ka whakaroahia te utu hei tiaki i te pākahiko.
I ia wāhanga, ka aroturuki tonu te whakahaere pāmahana atamai i ngā āhuatanga me te whakarerekē i ngā rautaki.
He aha te Whakahaere Pāmahana Atamai?
Ko te whakahaere pāmahana atamai he pūnaha whakakotahi o ngā pūoko, ngā rauropi whakahaere, me te hoahoa taputapu hei whakarite kia noho tonu ngā pāmahana i roto i ngā rohe haumaru me te kore e tino whakararu i te tere utu. Ka mahi tēnei pūnaha i te wā tūturu, ko te tikanga ka mahia ngā whakataunga i ia wā, i ia wā, tae atu ki te huri i ia hēkona i runga i ngā āhuatanga.
Ko ngā wāhanga matua ko:
– Pūoko pāmahana: he pūoko whakamahana, he pūoko matihiko rānei e whakanohoia ana ki te taha o te pākahiko, te IC utu, ā, i ētahi wā kei roto i te rohe hononga USB.
– IC whakahaere mana (PMIC): he maramara e whakahaere ana i te tohatoha mana, e whakatakoto ana i te iahiko/ngaohiko, ā, e tapahi ana i te utunga mēnā ka puta he āhuatanga morearea.
– Pūmanawa/raupapa: he arorau e whakatau ana i te wā e taea ai te whakanui, te whakaiti, te whakaū rānei i te mana.
– Pūnaha whakamarara wera (hoahoa wera): te hora wera, te pepa karāpeti, te rūma kohu, te anga konumohe, me te rauemi wera e kawe ana i te wera mai i te wāhi wera.
Ngā Rautaki Matua mō te Whakahaere i te Wera i te Wā e Utu Tere Ana
1. Whakarerekētanga Mana Hihiri (Utu Whakarerekētanga)
Engari mō te pupuri i te taumata mana teitei pumau, ka whakatikatika te taputapu i te mana i runga i te pāmahana tuturu. Mēnā ka kitea e te pūoko te pāmahana e tata ana ki tētahi paepae, ka whakaitihia e te pūnaha te iahiko, ka whakarerekētia rānei te kōtaha ngaohiko. Mā tēnei ka pōturi ake te utu, engari he haumaru ake, he pumau ake hoki.
2. Te Tohatoha Raina Utu (Papu Utu Maha-Pūtau, Papu Utu Takirua rānei)
Ka whakamahia e ētahi taputapu he hoahoa pākahiko pūtau-rua, he ara iahiko papu utu rānei hei tohatoha i te kawenga. Mā te wehewehe i te iahiko puta noa i ngā pūtau e rua, i ngā ara e rua rānei, ka taea te whakaiti i te wera i te pūwāhi kotahi. He maha ngā wā ka kitea tēnei hangarau i roto i ngā waea atamai tere-utu kaha rawa.
3. Te Aroturuki i te Neke atu i te Kotahi Wāhi Wera
Ehara i te mea ko te pākahiko anake te mea e aro turukihia ana e te whakahaere pāmahana atamai. Ko te IC utu, te rohe tauranga, tae atu ki te pāmahana taiao he mea nui anō hoki. Hei tauira, ka taea te whakaiti i te utu tere ina kei roto te taputapu i te motuka wera, i te wā rānei e takaro ana i te kēmu—nā te mea ka tāpirihia e te kawenga CPU/GPU tētahi atu pūtake wera.
4. Te Whakaterenga Wera Maeneene
E rangona ana te kupu "throttling" i roto i ngā tono pēnei i ngā tukatuka, engari he rite tonu te ariā mō te utu. Ko te rerekētanga ko ngā pūnaha hou e ngana ana ki te karo i ngā hekenga ohorere. Mā te whakahaere āta haere, kāore ngā kaiwhakamahi e pāngia e ngā pikinga utu nui, ā, he pumau ake ngā pāmahana.
5. Matapae Whanoke a te Kaiwhakamahi
Ka whakatinanahia e ētahi kaihanga te utunga urutau e whai whakaaro ana ki ngā whanonga a te kaiwhakamahi. Hei tauira, ina utu te kaiwhakamahi i te pō, ka taea e te taputapu te pupuri i te utunga ki tētahi taumata (hei tauira, 80–90%) kātahi ka utu ki te 100% i te wā e tata ana ki te wā oho ake ai. Ko te whāinga he whakaiti i te wā e pāngia ana te pākahiko e te ngaohiko teitei me ngā pāmahana teitei, kia roa ake ai tōna roa.
Te Pānga o te Whakahaere Pāmahana Atamai ki te Ora o te Pūhiko
E rua ngā āhuatanga nui e pāngia ana e ngā pākahiko lithium: te pāmahana me te roa o te ngaohiko teitei. Ka kino ake ngā āhuatanga e rua i te utu tere. Ki te kore he whakahaere pāmahana tika, ka taea e ngā huringa utu tere te whakatere i te hekenga o te kaha. Koia te take he maha ngā taputapu "ka tere te ahua" i te tīmatanga, engari i muri i te tau, e rua rānei, ka tere ake te mimiti o te pākahiko.
Mā te whakahaere pāmahana atamai, ka ngana te pūnaha ki te pupuri i te pākahiko i roto i te "rohe haumaru"—hei tauira, mā te whakawhāiti i te pāmahana mōrahi me te whakahaere i te wāhanga whakakī kia iti ake te kaha. Nō reira, ka taea tonu te utu tere me te whakaiti i te pakaru o te pākahiko.
Ngā Wero me ngā Whakaaetanga
Ahakoa te whanaketanga o te hangarau, kei reira tonu ētahi āhuatanga e kore e taea te karo:
– Tere vs pāmahana: ka tere ake te utu, ka uaua ake te pupuri i te pāmahana kia iti, inā koa i roto i ngā taputapu angiangi.
– Rahi o te taputapu: he iti noa te wāhi mō ngā pūnaha whakamatao o ngā waea atamai angiangi.
– Te kounga o te taura me te urutau: ka whakanui ake ngā taura kounga iti i te ātete, ka whakaputa wera, ā, ka ngaro te hiko o te pūnaha.
– Taiao: ka pā te pāmahana rūma, te pānga o te rā, te whakamahinga rānei o tētahi pouaka matotoru ki te tohatoha wera.
Nō reira, ka rerekē pea te wheako utu tere i runga i ngā āhuatanga. I roto i te rūma hauhautanga, ka roa pea te pumau o te taputapu i te kaha teitei. I tetahi atu taha, i roto i ngā taiao wera, ka heke pea ngā tere i te mea ka tiakina e te pūnaha ngā wāhanga.
Te Ao o te Ao: Te Utu Tere Haumaru, Whai Hua Ake hoki
I ngā rā kei te heke mai, ka tautokona te utu tere e te huinga o ngā hangarau: he nui ake ngā rauemi pākahiko ātete wera, he tika ake ngā pūoko, he rauropi e ahu mai ana i te ako mīhini, me ngā hoahoa wera matatau ake. Hei tāpiri, kei te whanake tonu ngā paerewa whānui pēnei i te USB PD kia ōrite, kia haumaru, kia whai hua ake hoki te pūnaha utu-taura-taputapu.
He mea nui anō hoki te mōhio o te kaiwhakamahi. Mā te utu i te pākahiko i te wāhi hauhautanga, te whakamahi i tētahi rihi me te taura kounga teitei, me te karo i te whakamahinga nui i te wā e utu tere ana, ka āwhina i te pūnaha whakahaere pāmahana kia pai te mahi.
Te Katinga
Ehara i te mea ko te "whakatere tere" anake te hangarau utu tere, engari ko te tuku haumaru i te mana nui ki ngā pākahiko tairongo. Ko te whakahaere pāmahana atamai he tūāpapa nui mō te pumau o te utu tere o ēnei rā: te aroturuki i ngā pūoko, te whakarerekētanga hihiri i te mana, te tohatoha i te kawenga, me te arotau i te hoahoa tohatoha wera. Ko te hua he wheako kaiwhakamahi watea ake me te kore e whakararu i te haumaru me te roa o te pākahiko. I tēnei wā o ngā taputapu hono tonu me te nekenekehanga tere, ko te whakakotahitanga o te utu tere me te whakahaere wera atamai ka noho tonu hei hangarau matua i roto i ngā momo hua hiko o ēnei rā me ngā rā kei te heke mai.
