He torutoru ngā mahi hei tatau i te mana pākahiko e hiahiatia ana mō tētahi poti hiko, ā, e whakawhirinaki ana ki ngā āhuatanga pēnei i te mana o tō motuka, te wā e hiahiatia ana hei whakahaere, me te pūnaha ngaohiko. Anei tētahi aratohu taahiraa-i-te-taahiraa hei āwhina i a koe ki te whakatau i te rahi pākahiko tika mō tō poti hiko:
Hipanga 1: Whakatauhia te Whakamahinga Mana o te Mōta (i roto i ngā Watts, Amps rānei)
Ko te whakatauranga o ngā mōtini poti hiko ko te nuinga o te wāNgā Wāti or Mana hōiho (HP):
-
1 HP ≈ 746 Watts
Mena kei roto i te Amps te whakatauranga o tō motuka, ka taea e koe te tatau i te mana (Watts) mā te whakamahi i:
-
Ngā Wāti = Ngā Waohiko × Ngā Āmio
Hipanga 2: Whakatau Tatau i te Whakamahinga o ia Rā (Te Wā Whakahaere i roto i ngā Hāora)
E hia ngā hāora e whakamaheretia ana e koe hei whakahaere i te motuka i ia rā? Nāu tēneiwā whakahaere.
Hipanga 3: Tātaihia te Hiahia Pūngao (Whatt-haora)
Whakareatia te whakapaunga hiko ki te wā whakahaere kia whiwhi ai i te whakamahinga hiko:
-
Pūngao e Hiahiatia ana (Wh) = Mana (W) × Wā Whakahaere (h)
Hipanga 4: Whakatauhia te Ngaohiko Pūhiko
Whakatauhia te ngaohiko o te pūnaha pākahiko o tō poti (hei tauira, 12V, 24V, 48V). He maha ngā poti hiko e whakamahi ana24V, 48V rāneingā pūnaha mō te whai huatanga.
Hipanga 5: Tātaihia te Pūhiko e Hiahiatia ana (Amp-haora)
Whakamahia te hiahia pūngao hei kimi i te kaha o te pākahiko:
-
Te Pūngao Pūhiko (Ah) = Te Pūngao e Hiahiatia ana (Wh) ÷ Te Ngaohiko Pūhiko (V)
Tauira Tātaitanga
Me kī tātou:
-
Mana mōtini: 2000 Watts (2 kW)
-
Te roa o te mahi: 3 hāora/rā
-
Ngaohiko: Pūnaha 48V
-
Pūngao e Hiahiatia ana = 2000W × 3h = 6000Wh
-
Te kaha o te pākahiko = 6000Wh ÷ 48V = 125Ah
Nō reira, me hiahia koe i te iti rawa48V 125Ahte kaha o te pākahiko.
Tāpirihia he Tapeke Haumaru
E taunaki ana kia tāpirihia20–30% te kaha tāpirihei whakaaro mō te hau, te ia, te whakamahinga tāpiri rānei:
-
125Ah × 1.3 ≈ 162.5Ah, whakaawhiwhi ki runga160Ah, 170Ah rānei.
Ētahi atu Whakaaroaro
-
Momo pākahikoHe nui ake te mātotoru o te pūngao o ngā pākahiko LiFePO4, he roa ake te ora, ā, he pai ake te mahi i te waikawa mata.
-
Taumaha me te wāhiHe mea nui mō ngā poti iti.
-
Te wā utuKia tino rite tō tautuhinga utu ki tāu e whakamahi ana.
