Hi Pablo, thanks for your reply.
In this case, I would guess to define maximum capacity and actual capacity of the battery in Wh as well. Otherwise the battery drain according to the consumption would make no sense. However, the documentation and the examples at http://sumo.dlr.de/wiki/Models/Electric clearly state that maximum capacity and actual capacity need to be defined in kWh. Kind regards, Karl.

We do it so to gain more precision. Regards —————————————————————————— Deutsches Zentrum für Luft- und Raumfahrt e.V.

We are trying to simulate energy consumption for electric vehicles without recuperation. To this end, we have taken your example of an electric vehicle configuration from your wiki and adapted it to what we think might fit a regular car (see below). However, we found that both - your example configuration and our adapted configuration - result in high energy consumption. A one minute drive almost drains 200 kw/h of battery load (log file attached). What can we do to achieve a more moderate energy consumption? Kind regards, Karl. <vType id="PKW" accel="1.5000" carFollowModel="Krauss" color="red" decel="4.5000" length="5.0000" maxSpeed="50.0000" minGap="2.5000" sigma="0.5000" tau="1.0000"> <param key="maximumBatteryCapacity" value="2000"/> <param key="vehicleMass" value="1800"/> <param key="frontSurfaceArea" value="2.0"/> <param key="airDragCoefficient" value="0.25"/> <param key="internalMomentOfInertia" value="0.01"/> <param key="radialDragCoefficient" value="0.5"/> <param key="rollDragCoefficient" value="0.01"/> <param key="constantPowerIntake" value="0"/> <param key="propulsionEfficiency" value="0.9"/> <param key="recuperationEfficiency" value="0.0"/> <param key="stoppingTreshold" value="0.1"/> </vType> ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ sumo-user mailing list [email protected]<mailto:[email protected]> https://lists.sourceforge.net/lists/listinfo/sumo-user ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ sumo-user mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/sumo-user
