Me Pēhea te Whiriwhiri i te Sel Bateri Tika mō Tō Kāwai

Te Mārama i te Hangarau Uira Wātea mō ngā Tinihanga Kua Whanaketia

Ko te whiriwhiri i te uira wātea tino pai mō tō tinihanga he waahanga matua e taea ai te whakapiki ake i te mahi, roa o te oranga, me te wheako kaiwhiltri. Kia tupu haere tā tātou here ki ngā taputapu pūkoro e taea ai te karapoti, ka nui ake te takotoranga o te whiriwhiringa i te uira wātea tika. Mai i ngā waea ringaringa, ngā rorohiko ki ngā waka inuhi, hoki rānei ki ngā taputapu hauora, e hiahiatia ana e ia tono ngā herehere hiko e kīia ana anake e ētahi atu ngā uira wātea e taea ana te tuku.

Kua whanaketia te ao o ngā uira wātea i te tekau tau kua pāhua, e tuku ana i tētahi tauira whānui o ngā kimihana, rahi, me ngā korero pakari. Ka āwhina tēnei aratohu whānui i a koe kia kitea te ara angitu o te hangarau uira kia taea ai te whiriwhiri mō ō hiahia motuhake.

Ngā Tūtohu Matua o te Sel Bateria

Ngā Taipitopito Mō Te Tahumaero me Te Marumaru

Ko te tahumaero me te marumaru o tētahi sel bateria ngā whakamāharatanga matua e whakatau ana i tōna ū mō te taputapu. Me tautū ana te tahumaero ingoa, e hāngai ana mai i te 1.2V ki te 3.7V kia rerekē ai te kimikara, ki ngā here o tō taputapu. Ko te marumaru, e ine ana i ngā māhao milliampere (mAh) némpi ampere-hora (Ah), e whakaatu ana i te nui o te hiko e taea e te sel bateria te penapena. Heoi anō, ko te marumaru teitei ake he wā roa ake te aronga, engari me tino āhua tēnei ki ngā here o te rahi me te taumaha.

Ina arotake ana i ngā taipitopito o te sel bateria, me whai whakaaro ki ngā here hiko pīkau me te pī tonu mō tō taputapu. E hiahiatia ana pea tētahi sel e taea ai te wera hiko nui mō ngā taputapu e hiahiatia ana te hiko, i te mea e taea pea tētahi sel iti ake mō ngā whakamahinga iti ake.

Ngā Rāwekenga Arotahumaoro me ngā Huinga

Ko ngā seli papatara i ngā whānuitanga rerekē, tae atu ki ngā pepa pōro (18650, 21700), ngā pepa tapatoru, me ngā seli pūkete. Ko ngā here tinana o tō taputapu ka whakatau ai pēhea ngā āhua e taea ana. E tuku ana ngā seli pōro i te tōaitanga tinana pai, ā, kua whakamahia whānui ki ngā rorohiko mātātoko me ngā taputapu hiko. E tuku ana ngā seli tapatoru i te whai wāhi tino mōhio, ā, he nui ake i ngā waea pūkoro. Ko ngā seli pūkete e tuku ana i te kotahi te arataki energi teitei rawa, engari me tāwhai atu i te tiaki.

Whakaaro kaua anō ko ngā here o te rahi o nāianei engari ko ngā panonitanga, whakahou rānei ka taea mō tō taputapu. He mea mataara kia waiho ētahi mometane mō te whakahaere wera me ngā sircuits tiaki ina whiriwhiria ana tētahi āhua seli reka.

Te Whiriwhiringa Matū me ng Āhuatanga Mahi

Ngā Takotoranga Līthiama-Ion

Ko te mātai matū Lithium-ion tonu te kōpae matū matua, e tuku ana i te āhua pai o te nekeneke o te hiko, te ora whakateretere, me te utu. I roto i te whānau lithium-ion, e etahi rerekētanga, ko ia tetahi he ake ōna āhuatanga motuhake. Ko ngā sel NMC (Nickel Manganese Cobalt) e tuku ana i te nekeneke hiko teitei e hāngai ana mō ngā taputapu nukumove. Ko ngā sel LFP (Lithium Iron Phosphate) e tuku ana i te haumātauranga me te roa o te wā, ka hāngai ai mō ngā whakamahinga tuarangi me ngā whakamahinga hangarau.

Me āwhina te kōwhiringa matū lithium-ion ki āu hiahia matua. Mēnā ko te wā roa rawa te mea nui, whakaaroa ngā kōwhiringa hiko-teitei. Mēnā ko te haumātauranga me te roa o te wā te mea matua, ko LFP pea te kōwhiringa pai ake ahakoa he iti ake te nekeneke o te hiko.

Ngā Kōwhiringa Matū Kōrero Kē

I tua atu i te lithium-ion, ko ētahi atu matū pūtau pūhiko e mahi ana i ngā wāhi motuhake. Ko ngā pūtau Nikel-Metal Hydride (NiMH) e tuku ana i te mahi pai ki te utu iti iho, ahakoa he iti ake te taumaha pūngao. Ko ngā pūtau waikawa-whatu, ahakoa he taumaha, he nui hoki, he pai tonu mō ngā tono kāore te taumaha i te mea matua, ā, he mea nui te whai hua o te utu.

Ko ngā hangarau hou pēnei i ngā pūhiko pūngāwerewere e whakaari ana i te haumaru me te pūngao kaha ake, ahakoa he iti tonu te wātea o te hokohoko. I te kōwhiri i tētahi matū, kaua e whakaaro noa ki ngā hiahia o nāianei engari ki te pakeke o te hangarau me te wātea mo te wā roa.

Ngā āhuatanga taiao me ngā āhuatanga whakahaere

Ngā Whakaaetanga o te Waimā

Ko te taiao whakahaere e pa ana tino ki te mahi me te roa o ngā wae pū. E mahi pai ana te nuinga o ngā wae pū i waenganui i te 20°C ki te 30°C, ā, ko ngā whākinga nui e pa ana ki te kapa, ngā pūkenga uta, me te ora-wae. Ko ngā teperetia teitei e huritau ana i te pakeke, ā, ka taea hoki e ia te whai mōrearea haumaru, kei te heke haere hoki ngā teperetia iti i te kapa wātea me te mariko uta.

Mō ngā taputapu e whakahaere ana i ngā tikanga tino herekau, ka hiahiatia pea ngā wae pū motuhake i hangaia mō te whakahaere i te teperetia teitei, i te iti rānei. Ko ēnei he nuinga o ngā kimikara rerekē, i te āhua atawhai hoki kia mau ai te haumaru me te whakapau pono i runga i te tauwāhi whānui ake o te teperetia.

Ngā Tautohe Haumaru me te Atawhai

Kāore ever i te tika kia whakakaha ngā whakaaro mō te haumātao i te whiriwhiri i tētahi wāhi pūhiko. Ko ngā tono rerekē e here ana i ngā rākau rerekē ki te aukati i te tino uta, te tino whakaputangia, ngā huarahi poto, me te rere tūmate. Hei tauira, e manaaki ana ngā taputapu hauora i ngā wāhi e whai pūmanawa haumātao tino pai ana, ā, he nui ngā tikanga aukati tuarua.

Whakamātau i ngā āhuatanga aukati kei roto i te wāhi, ka whakaaro hoki ki āhea e hiahiatia ana ētahi anuanu aukati atu anō. Kei ētahi wāhi ko ngā taputapu PTC roto, i runga rānei i ngā tikanga CID, ā, kei ētahi atu anō anō pea ngā anuanu aukati waho.

Ngā Whakaaro mō Te Utu me Te Huinga Tuku

Whakamātauranga Tahumaero

Ka torutoru ake te utu o te whakaurunga i tētahi ratonga wāhi pūhiko i te utu kotahi. Me whakaaro ki ngā utu mō ngā anuanu aukati, ngā punaha whakahaere wera, me ētahi whai mōhio e herea ana. Ka taea e te utu rahi te whai pā ki te mutunga o te utu, nō reira he mea nui te whakamātau i ngā kaihautū rerekē me ngā rahinga iti e hiahiatia ana.

Whakauruhia te matapae mō te roa o te ora me ngā wāhanga whakakapi i te tātai i te utu tino nui. Mā te wāhanga ārai tūtahi eke ake te utu engari he roa ake te wā o te wāhanga, ka tino iti ake te utu i te roanga o te wā i tētahi atu e iti ake te utu engari me te whakakapi marino.

Whakapauaro Tukutuku

Whakaritea kia ū ki te huinga uaua o te pūhiko e kōwhiri ana koe me ngā kaihanga mōhio maha. Ko ngā here ki tētahi puna anake e waiho ana hei raru nui mō te wātea o ngā hua. Whakamātauria te hītori o te kaihanga, te kapaiti hua, me te āhua e taea ai te tutuki i ngā paerewa kounga me ngā here tuku.

Whakamātau i te wātea roa-roa o te momo pūhiko i kōwhiria e koe, ina nui ake mō ngā hua e roa ana te wā o te ratonga. Mā te whai puna takotoranga rerekē, takotoranga rānei e ono ana, ka taea te whakaroa i ngā raru o te huinga uaua.

Ngā Pātai e Patai Pūnoa Ana

E hia te tau e tika ana kia ora ai tētahi pūhiko?

Ko te roa o te ora o tētahi wā kōpae rerehua e rerekē ana e te mātauranga kimihana, ngā hīkoi whakamahi, me ngā tikanga taiao. Ka pupuri ake te nuinga o ngā wā kōpae rerehua-rihiata i te 80% o tō rātou kaha taketake i muri i ngā 500-1000 wehenga uta i ngā tikanga pai. Engari, ka taea te haerenga mai i te 300 ki te 3000 anuanu, e hāngai ana ki te kimihana iti me ngā here whakamahinga.

He aha ngā tiwhikete haumātauranga e tika ana kia titiro mātou ki tētahi wā kōpae rerehua?

Ko ngā tiwhikete matua ko UL 1642 mō ngā kōpae rerehua-rihiata, IEC 62133 mō ngā whakamahinga pūrere, me UN 38.3 mō te haumātauranga kawenga. Ko ngā taputapu hauora pea e hiahiatia ana ētahi atu tiwhikete pērā i te IEC 60601-1. Me tirotiro tonu kia hou ngā tiwhikete, me tika hoki mō tō pātaka me tō whakamahinga e hiahia ana koe.

Taea rānei e au te whakakapi i tētahi kimihana wā kōpae rerehua ki tētahi atu?

Ahakoa e taea ana te whakakapi i ētahi atu kimihana pū, kāore e tūtohu noa mēnā kāore he tātari inžiniera. He rerekē ngā kimihana ki ngā aronga volta, ngā here utu, me ngā āhuatanga haumātao e hiahiatia pea he panonitanga nui ki te punaha whakahaere hiko me ngā waitohu tiaki o te taputapu.
