2. Cov txheej txheem suav
Core Formulas
1. Kev siv zog ib teev:Kev siv ib teev (kWh) = Kev Siv Txhua Hnub / 24
2. Tag Nrho Cov Hluav Taws Xob:Tag Nrho Zog = Kev Siv Sij Hawm × Cov Sijhawm Thaub
3. Roj Teeb Muaj Peev Xwm:Roj teeb (Ah) = (Tag nrho Zog × 1000) / (DOD × Efficiency × Voltage)
4. Inverter Qhov Loj:Inverter (kW) = Peak zog × 1.2
5. Lub Sijhawm Them Hnub Ci (yeem):Cov Sijhawm Them = Tag Nrho Lub Zog / ( Hnub Ci Loj × Ua Haujlwm)
3. Ua piv txwv
Cov ntaub ntawv piv txwv
- Kev siv txhua hnub: 25 kWh
- Lub Sijhawm Teev Tseg: 36 teev
- Lub cev muaj zog: 7.5 kW
- Roj teeb: Li-Ion (DOD = 0.8)
- Lub cev muaj zog: 48V
- Inverter Ua Haujlwm: 92%
- Hnub ci vaj huam sib luag: 5 kW
Kev suav cov kauj ruam
- Kev siv ib teev: 25/24 = 1.042 kWh
- Tag nrho cov zog: 1.042 × 36 = 37.5 kWh
- Roj teeb muaj peev xwm: (37.5 × 1000) / (0.8 × 0.92 × 48) = 1,118 Ah
- Inverter Loj: 7.5 × 1.2 = 9 kW
- Them sij hawm: 37.5 / (5 × 0.92) = 8.15 teev
4. Cov Lus Qhia Engineering
Kev txiav txim siab tseem ceeb
- Ntxiv 15-20% muaj peev xwm tsis rau roj teeb laus
- Kub derating yam:
- +35 ° C: × 0.9 hli
- -10 ° C: × 0.75 hli
