Ngā Pūhiko Pūmanawa Teitei mō ngā Pūrere Hiko
I roto i ngā tekau tau kua pahure ake nei, kua tere te whanaketanga o ngā taputapu hiko: kua angiangi haere ngā waea atamai, kua māmā haere ngā pona, kua matatau haere ngā mataaratanga atamai, ā, kua "atamai" haere ngā taputapu kāinga nā te hononga ipurangi. Kei muri i ēnei ahunga whakamua katoa tētahi wāhanga nui engari e warewarehia ana: ko te pākahiko. Ki te kore he pākahiko pono, kāore e taea te kawe i tētahi taputapu kawe. Koia te take i noho ai ngā pākahiko kaha-nui hei kaupapa nui—ehara i te mea mā ngā kaihanga anake, engari mā ngā kaiwhakamahi hoki e hiahia ana kia roa ake te ora o te pākahiko, kia iti ake te auau o te utu, me te wheako kaiwhakamahi pumau.
He aha te Pūhiko Kaha Teitei?
I te whakarapopototanga, ko te kaha o te pākahiko te nui o te kaha ka taea e ia te penapena, ā, ka whakamahia hei whakakaha i tētahi taputapu. Ko te kaha ka inehia i roto i ngā hāora-mīriamita (mAh) mō ngā taputapu iti pēnei i ngā waea pūkoro, i roto rānei i ngā hāora-watt (Wh) mō ngā taputapu nui pēnei i ngā pona. Ko te tikanga o tētahi pākahiko kaha-nui ka taea e ia te penapena kaha nui atu i tētahi pākahiko tuku iho o taua momo, o taua rahi rānei, kia roa ake ai te oma o te taputapu i mua i te hiahia kia whakakīia anō.
Heoi, e rua ngā huarahi e taea ai te whakamārama i te "kaha nui". Tuatahi, e pā ana ki te kaha nui (hei tauira, he pākahiko 6000 mAh i roto i te waea pūkoro). Tuarua, e pā ana ki te kaha nui o te pūngao, arā, te kaha ki te penapena i te nui o te pūngao i roto i te rahi me te taumaha iti. Mō ngā taputapu hou e whakatairanga ana i ngā hoahoa angiangi, ko te kaha nui te mea nui.
He aha i nui haere ai te hiahia mō te kaha teitei?
Kei te piki haere te hiahia mō ngā pākahiko kaha-nui i te mea ka huri ngā tauira whakamahinga taputapu. Ehara i te mea ko ngā waea pūkoro he taputapu whakawhitiwhiti kōrero anake, engari he kāmera, he taputapu mahi, he mahere whakatere, he putea matihiko, he pokapū whakangahau hoki. Ko ngā mahi pēnei i te rere ataata, te petipeti, te waea ataata, me te whakamahinga GPS ka tere ake te pau o te hiko i te waea me te tuku karere kuputuhi o mua. I tenei wā, kāore ngā pona e herea ana ki ngā tēpu; he maha ngā tāngata e mahi mamao ana, e haere ana ki ngā hui ipurangi, ā, e whakawhirinaki ana ki ā rātou pākahiko mō te hua o ia rā.
I tētahi atu taha, ko ngā āhuatanga e whanake haere ana e hiahia ana ki te kaha ake: ngā whakaaturanga whakahou tere teitei, te hononga 5G, ngā pūoko koiora, me ngā wāhanga AI rerekē kei runga i te taputapu. Ko te nui ake o ngā āheinga e whakauruhia ana e te taputapu, ko te teitei ake o ngā whakaritenga pūngao. Nō reira, ko ngā pākahiko kaha teitei te whakautu ki ēnei tono.
Te Hangarau Pūhiko Matua o Tēnei Rā
Ko te nuinga o ngā taputapu hiko hou e whakamahi ana i ngā pākahiko lithium-ion (Li-ion) lithium-polymer (Li-Po) rānei. He pai ake ngā āhuatanga o ēnei e rua: he nui te kaha o te pūngao, he pai te whai huatanga, me te kaha ki te whakahou i ngā rau huringa. I roto i te mahi, he maha ngā pākahiko waea pūkoro e kiia ana ko Li-Po, ahakoa kei roto tonu i te whānau lithium-ion ō rātou matū. Ko ngā rerekētanga matua kei roto i ō rātou āhua ā-tinana me te momo electrolyte, e ngāwari ake ai mō ngā hoahoa angiangi.
Heoi anō, kāore te hangarau lithium e kore e raru. Ka taea e te whakamahinga nui me te utu tere te whakanui ake i te pāmahana, ā, ka tere ake te pirau o te pākahiko i ngā pāmahana teitei. Nō reira, ehara i te mea he "nui" noa iho te pākahiko kaha-nui; me tautokona e te pūnaha whakahaere pākahiko pakari (BMS), ngā rauemi kounga teitei, me te hoahoa wera haumaru.
Ngā Āhuatanga e Whakatau ana i te Mahi Pūhiko Kaha-Tiketike
He maha ngā āhuatanga e whakatau ana mēnā he tino whai hua te pākahiko kaha-nui:
1. Te mātotoru o te pūngao: ka nui ake te mātotoru, ka nui ake te mana i te wāhi kotahi. He mea nui tēnei mō ngā waea tino angiangi me ngā taputapu mau.
2. Te tere tukunga: me kaha te pākahiko ki te tuku i ngā iahiko nui mō ngā hiahia mahi tino pai pēnei i te petipeti, te whakaata rānei.
3. Te roa o te huringa utu: Ka mau tonu te kaha o ngā pākahiko kounga teitei mō te wā roa. Ki te tere te pirau o te pākahiko, ka iti ake te hiranga o tōna kaha teitei i te tīmatanga.
4. Haumaru: He mea nui te tiaki i te hiko mai i te nui rawa o te hiko, te nui rawa o te iahiko, me ngā ara iahiko poto. Ko te nui ake o te kaha ko te nui ake o te penapena hiko, ā, he mea nui ake te haumaru.
5. Te whakahaere i te pāmahana: Ko te wera te hoariri matua o te pākahiko. Ko ngā taputapu he pai te hoahoa whakamatao ka roa ake te ora o te pākahiko.
Te Pānga o te Utu Tere ki te Pūhiko
Kua rongonui te utu tere. Mā te kaha nui, ka taea te utu i ngā pākahiko mai i te 0–50% i roto i te wā poto. Heoi, ka taea e ngā ia utu nui te whakanui ake i te wera me te ahotea matū i roto i ngā pūtau pākahiko. Kei te aro atu ngā kaihanga ki tēnei take mā ngā hangarau pēnei i te utu pūtau-rua hei whakahaere i te ngaohiko me te ia kia haumaru ake, me te pūnaha utu ā-wāhanga e whakaroa ana i te utunga ina tata ki te 80–100%.
Ki ngā kaiwhakamahi, ko te mea nui kia mārama he watea te utu tere, engari kāore i te pai i ngā wā katoa mēnā ka mahia tonutia i roto i ngā āhuatanga wera. Mā te utu tere i te wā e whakamahia ana te taputapu (hei tauira, te tākaro kēmu) ka taea te whakanui ake i te pāmahana me te tere ake te heke o te kaha. Ka roa ake te ora o ngā pākahiko kaha-nui mēnā ka whakahaerehia i roto i te awhe pāmahana e tika ana, me ngā tikanga utu tika.
Ngā Pūhiko Pūmanawa Teitei i roto i ngā Pūrere Rerekē
Ko ngā waea atamai te tauira tino kitea. He mea noa ngā pākahiko 5000–6000 mAh i ēnei rā, inā koa i roto i ngā waea e whakatairanga ana i te roa o te pākahiko. Heoi, i ētahi wā ka whiriwhiria e ngā waea matua ngā kaha iti ake mō ngā hoahoa angiangi, hei whakauru rānei i ngā kāmera me ngā pūnaha whakamatao.
Ka inehia e ngā pona te kaha o te rorohiko Wh. Ko ngā pona Slim te nuinga o te wā kei waenga i te 40–70 Wh, engari ko ngā pona mahi, ngā pona kaihanga rānei ka nui ake. Heoi, ko ngā ture rererangi e hiahia ana i ngā pākahiko kia nui ake i tētahi kaha, nō reira he maha ngā wā ka whakatauritehia e ngā kaihanga te kaha me te ngāwari ki te kawe.
Ahakoa he rerekē ngā wero, ka whai hua anō ngā papahiko me ngā taputapu mau i ngā pākahiko kaha-nui. Me whakamahi ngā pākahiko iti, whai hua hoki mō ngā taputapu mau nā te mea he iti noa te wāhi. Nō reira, he rite tonu te hiranga o te arotau pūmanawa, ngā whakaaturanga penapena-pūngao, me ngā pūoko whai hua ki te kaha o te pākahiko.
Te Tūranga o te Pūmanawa me te Whai Huatanga Pūngao
Ehara i te mea ko te pākahiko nui anake te otinga. Ko te pai o te maramara, te arotautanga o te pūnaha whakahaere, me te whakahaere taupānga papamuri ka pā nui ki te roa o te pākahiko. He maha ngā taputapu hou e whakamahi ana i ngā tukatuka me ngā hoahoa penapena-pūngao me ngā hangarau hanga iti haere (hei tauira, 4nm, 3nm rānei) hei whakaiti i te whakapaunga pūngao. Ka āwhina hoki ngā whakaaturanga OLED mā te whakaweto i ngā pika i ngā wāhi pōuri. Mā te whakakotahitanga o te pākahiko kaha-nui me te pai o te pūnaha ka roa ake te ora o ngā taputapu me te kore e whakaiti i te mahi.
Ngā Tohutohu mō te Whakanui i te Ora o ngā Pūhiko Kaha-Tiketike
Hei pupuri i te hauora o te pākahiko, ka taea e ngā kaiwhakamahi te whai i ētahi tikanga māmā:
– Āta karohia ngā pāmahana tino kino, inā koa te wera nui.
– Whakamahia he rihi kounga e tutuki ana i ngā paerewa o te taputapu.
– Mēnā kei te wātea, whakahohehia te āhuatanga "tiaki pākahiko" me te whakawhāiti rānei i te utunga ki te 80–85% mō te whakamahinga o ia rā.
– Kaua e tukua te pākahiko kia pau rawa i ngā wā katoa.
– Whakaitihia te tikanga o te utu i te pākahiko i te wā e whakahaere ana i ngā taupānga taumaha mō te wā roa.
Mā tēnei tikanga ka āta haere te pirau kia noho whai hua ai te kaha nui mō te wā roa.
Te Anamata: Te Auahatanga i tua atu i te Lithium-ion
Kei te haere tonu te rangahau mō ngā pākahiko. Ko tētahi huarahi whai hua ko ngā pākahiko totoka-āhua, e whakakapi ana i ngā irahiko wai ki ngā irahiko totoka hei whakapai ake i te haumaru me te whakahohe i ngā kiato pūngao teitei ake. Kei te rangahauhia anō hoki te konutai-ion hei huarahi kē atu i te iti ake te utu me te nui ake, ahakoa me whakapai tonu tōna kiato pūngao kia whakataetae ai ki ngā taputapu utu nui. Hei tāpiri, ko te whakawhanaketanga o ngā rauemi anode pēnei i te silicon he kaha anō hoki ki te whakanui ake i te kaha, ahakoa ko te wero o te whakawhānui rauemi i te wā o ngā huringa utu he arotahi tonu ki te rangahau.
Whakamutunga
Ko ngā pākahiko kaha-nui te poutokomanawa o ngā taputapu hiko hou. Ka tutuki i a rātou ngā hiahia o te nekenekehanga me te hua, me te whakahohe i ngā āhuatanga matatau ake me te kore e rapu tonu i tētahi putanga hiko. Heoi, me whai hangarau haumaru, whakahaere wera, me te arotau pūmanawa te kaha-nui kia pai ai te roa me te roa o te ora. I te tirohanga whakamua, ka oati ngā auahatanga pēnei i ngā pākahiko totoka me ngā rauemi hou ki ngā pikinga nui ake, kia pono ake ai, kia haumaru ake ai, kia roa ake ai hoki ngā taputapu hiko mō te whakamahinga o ia rā.
