Regen
- Ensure maximum regen are in settings.
- This value can almost never be more than the total output in kW.
- Probably some efficiency loss here, 0.9?
DC to AC Inverter Efficiency
- Standard around 95%
- SiC around 97.5%
Motor Efficiency
- EPact 84% - 92.5%
- NEMA Premium and Super Premium 86.5% - 94.1%
- Permanent Magnet efficiency = 92% - 97%
Rolling resistance
- Car tire: 0.010 - 0.015
- Rain on road: 0.02
- Snow on road: 0.05 - 0.075
- Gravel road: 0.020 - 0.035
Tire contact area
Heater Consumption
- Calculate watts required to maintain cabin temperature compared to ambient temperature.
- Calculate watts required to maintain battery at 15-35° (20-25°C I think is best)
- Wind chill on cabin?
Heat pumps generally are around 700W - 1000W and will generate heat around 2-3kW
Resistance heat: Around 20C - 0W Around 10C - 300W Around 0C (freezing point) 1000W Around -10C - 2000W Around -20C - 3000W
With heat pump: Around 20C - 0W Around 10C - 100W Around 0C (freezing point) 200W Around -10C - 700W Around -20C - 3000W
