I'm sorry but I don't think I understood all your questions. Your outputfile shows a vehicle that did not charge any energy (presumably because it was stopped somewhere where there was no chargingStation. Vehicles can only recharge their battery in either of the following cases - they are passing a chargingStation and that chargingStation has attribute chargeInTransit="true" - they are stopped (or with speed below stoppingThreshold) at a chargingStation - they are braking from high speed and their recuprationEfficiency is > 0
1) no. chargeInTransit is a user-specified chargingStation attribute 2) yes. recupration from braking is independent of chargingStations 3). I don't understand what you tried to say 2018-06-17 0:47 GMT+02:00 Jane Cheung <[email protected]>: > Hi Jakob, > > Thanks for your reply! > I have made some demo to simulate the EVs with different values on the > attribute of StoppingTreshold and Ihave find some result like the picture > shown below > [image: 0.0000.png] > There are some other understanding of the attribute of cars： > 1) whether the attribute of *chargeInTransit is positive or not > depends on the difference of speed timestep by timestep;* > *2) There is no relationship between the 5th and 6th attributes;* > 3) If someone wants to simulate the charging and discharging behavior of > EVs and do not want any information of Charging Station, they could add > STOPS for EVs to simulate the charging at the specific location without > defining Charging Station.
