Ko te tatau i te mana o te pākahiko e hiahiatia ana mo te poti hiko he iti noa nga waahanga ka whakawhirinaki ki nga ahuatanga penei i te mana o to motuka, te waa e hiahiatia ana, me te punaha ngaohiko. Anei he aratohu taahiraa-i-taahiraa hei awhina i a koe ki te whakatau i te rahi o te pākahiko tika mo to poti hiko:
Hipanga 1: Whakatauhia te Whakamahi Hiko Motini (i Watts, Amps ranei)
Ko nga motuka poti hiko e kiia ana i rotoWatts or Horsepower (HP):
-
1 HP ≈ 746 Watts
Mena kei te Amps to whakatauranga motuka, ka taea e koe te tatau i te hiko (Watts) me:
-
Watts = Volts × Amps
Hipanga 2: Whakatauhia te Whakamahinga Ia Ia (Waima i roto i nga Haora)
E hia nga haora e whakamahere ana koe ki te whakahaere i te motini ia ra? Ko to teneiwā whakahaere.
Hipanga 3: Tātaihia te Whakaritenga Pungao (Watt-haora)
Whakareatia te kohi hiko ki te wa whakahaere ki te whakamahi hiko:
-
Hiahia Pungao (Wh) = Hiko (W) × Wā Whakahaere (h)
Hipanga 4: Whakatauhia te Ngaohiko Pūhiko
Whakatauhia te ngaohiko punaha pākahiko o to poti (hei tauira, 12V, 24V, 48V). He maha nga poti hiko e whakamahi ana24V ranei 48Vnga punaha mo te whai hua.
Hipanga 5: Tātaihia te Rahi Pūhiko (Amp-haora)
Whakamahia te hiahia ki te kimi i te kaha o te pākahiko:
-
Raukaha Pūhiko (Ah) = Pūngao e Hiahia ana (Wh) ÷ Ngaohiko Pūhiko (V)
Tauira Tatau
Me kii tatou:
-
Te mana motopaika: 2000 Watts (2 kW)
-
Wā whakahaere: 3 haora/ra
-
Ngaohiko: Pūnaha 48V
-
Hiahia te Pungao = 2000W × 3h = 6000Wh
-
Raukaha Pūhiko = 6000Wh ÷ 48V = 125Ah
Na, ka hiahia koe i te iti rawa48V 125Ahkaha pūhiko.

E taunaki ana kia taapiri20–30% te kaha taapiriki te whakaaro mo te hau, te naianei, te whakamahi taapiri ranei:
-
125Ah × 1.3 ≈ 162.5Ah, porowhita ake ki160Ah, 170Ah ranei.
Ētahi atu Whakaaro
-
Momo pākahiko: Ko nga pākahiko LiFePO4 he nui ake te kiato o te kaha, te roa o te ora, me te pai ake o te mahi i te waikawa mata.
-
Te taumaha me te waahi: He mea nui mo nga poti iti.
-
Te wa utu: Me whakarite kia rite to tatūnga utu ki to whakamahi.
