I know real-world scenarios where we saw consumption over 50kWh for 100 km. Depends on driving style, speeds, weather, and many other factors. I would check your vehicle parameters: For me, the Tesla with a 239 kWh engine is an sports car, and given unfavourable road conditions the acceleration and deceleration may be high, and hence the consumption may go up. It's indeed worth further analysis...As a rule of thumb, with current EVs we expect consumption about 15-20 kWh per 100 km in favourable conditions (summer tyres, no heating or air conditioning). In winter, this goes up to 30 or 40 kWh per 100 km. An average consumption with eg. VW Golf Electric over two years was about 20 kWh / 100 km (but that car was kind of a joke).But again, that's just observation, we did no rigid analysis of EV consumption here.Hope this helps.JanEl jue, 30 sept 2021 a las 18:09, Jakob Erdmann (<namdre.sumo@xxxxxxxxx>) escribió:maybe...Am Do., 30.

In the paper Kurczveil, T., López, P.A., Schnieder, E., Implementation of an Energy Model and a Charging Infrastructure in SUMO you have an example with an electric bus. Use these parameters in your vehicle and check if the result is coherent with your expected result. If not, send me network and route file.

I’m working on a simulation of an electric vehicle going from one city to another. Total distance is 100km and the vehicle has the following parameters:
- max speed (m/s) = 33.3 m/s (100 km/h)
- speedFactor = 1
- has.battery.device = true
- maximumBatteryCapacity (Wh) = 50.000 Wh.
- maximumPower (W) = 239.000 W.
- vehicleMass (Kg) = 1700 kg.
- frontSurfaceArea (m²) = 2.34 m².
- airDragCoefficient = 0.23.
- internalMomentOfInertia (kg m²) = 0.01 kg m².
- radialDragCoefficient = 0.5
- rollDragCoefficient = 0.01
- constantPowerIntake (W) = 50 W
- propulsionEfficiency = 0.9. .
- recuperationEfficiency = 0.9.
- stoppingTreshold (km/h) = 0.1.
- actualBatteryCapacity (Wh): 50.000.
Simulation has 3600 steps, step-length of 1 second.
The battery output says that the battery has been almost entirely consumed, and this doesn’t make any sense cause 50.000 Wh of battery capacity should last for around 300 km.
Is there any parameter I am misunderstanding or assigning an incorrect value?
I am trying to reproduce some features of Tesla Model 3 with maximumBaterryCapacity, maximumPower and vehicleMass.
