Apologies for my classically anglo-centric assumption - in my defence the
consumption reported was absurd! :)
I hadn't realised the EV model had been added to Sumo and am very interested in
this - I had a look at the model behaviour using my own vehicle (soul 2020).
The consumption values were similarly absurd and a sensitivity analysis
indicated that vehicleMass, radialDragCoefficient and the efficiency values
have most impact on the model.
For my Soul EV, against a round trip school run for which I have consistent
consumption values, the following gives me model output comparable to real life.
<vType id="soulEV" accel="1.0" decel="1.0" length="4.2" maxSpeed="167.0"
sigma="0.0" minGap="2.5" color="1,1,1">
<param key="has.battery.device" value="true"/>
<param key="maximumBatteryCapacity" value="64000"/>
<param key="maximumPower" value="150000"/>
<!-- wt = 1682kg - payload = 498kg = all passengers - so assume 200kg for 2
passengers + kit -->
<param key="vehicleMass" value="1882"/>
<!-- height = 1.600, width = 1.800, clearance = .155 front SA =
1.800*(1.600-0.155) -->
<param key="frontSurfaceArea" value="2.6"/>
<param key="airDragCoefficient" value="0.35"/>
<param key="internalMomentOfInertia" value="0.01"/>
<param key="radialDragCoefficient" value="0.1"/>
<param key="rollDragCoefficient" value="0.01"/>
<param key="constantPowerIntake" value="100"/>
<param key="propulsionEfficiency" value=".98"/>
<param key="recuperationEfficiency" value=".96"/>
<param key="stoppingTreshold" value="0.1"/>
<param key="emissionClass" value="Energy/unknown"/>
</vType>
I suggest you look at reducing the radialDragCoefficient as I'm pretty sure
that would be much higher for a bus than a Model 3! I have not yet looked at
how these parameters fit with longer/faster (non-urban) routes.
I'm interested in incorporating temperature impacts into the sumo model - much
more significant for an ev - if no-one is working on this I'd probably start
with the data from https://www.geotab.com/blog/ev-range/ and apply this to the
energy consumption/recuperation.
The question is where the temperature value should be set in sumo - it feels
like setting the value against an edge would be technically accurate but too
granular - whilst setting it for a simulation run may be too inflexible - any
thoughts?
cheers
