Re: [sumo-user] Some parameters in defining the Electrical Vehicles
Additional questions, 
1) My understanding of  the reply is that the rules that SUMO used to check whether cars had a braking behavior  or not  has no relationship with the attribute stoppingTreshold,
2) There are  two defined ways that EVs could choose when they are charging (moving or stable. The  stoppingTreshold have the function to let SUMO decrease the speed if CharingStation was also defined in the simulation and the  attribute chargeInTransit is set to be  'false'. if the understanding is right, it would mean that the  attribute stoppingTreshold has no use no matter what value it was defined when the  chargeInTransit  is "true"?

Regards!

4 is a factor between physical energy requirement and battery drain
5 is a factor between physical energy recuperation and battery charging (0 means no energy is recovered when braking, 1 means all is recovered)
6: charging stations can be configured to either charge moving vehicles or only stopped (attribute chargeInTransit). The stoppingThreshild defines an upper speed boundary that determines whether vehicles are considered as 'stopped' so they will be charged by these stations.

Hi, 
There are some parameters that I want someone could explain to me. There has no more detail information for these parameters. Appreciate for your help in advance.

As shown on the website of
  1. internalMomentOfInertia 
  2. radialDragCoefficient 
  3. ollDragCoefficient 
  4. propulsionEfficiency
  5. recuperationEfficiency 
  6. stoppingTreshold 
For the index  stoppingTreshold, does it have the relationship with the parameter  cuperationEfficiency? The speed threshold used to define braking behavior refers to the  stoppingTreshold?   In other words, if the car's speed is less than the value defined by the  stoppingTreshold, the cars are going to be charging? In my opinion,  whether the cars are going to charge or use the battery energy depends on the difference of the speed in between the simulation step. If the speed is always less than than the parameter  stoppingTreshold,  the cars are going to be charging all the time?
Could someone give a more detailed explanation for the 1-6 index listed above.

Appreciate for your reading it! Thanks!


Jane
