Re: [sumo-dev] Discussion on EV Rerouting with Stationfinder Device

Hi Haotian,

 

the stationfinder device is working in this case, but gives the wrong advice. The main problem with your simulation is that you test a corner case:

• very small battery
• high energy consumption
• low initial charge
• short route
  •  the predicted consumption is either based on historical data for longer routes or on few assumptions for short routes
  • underestimating the consumption for short routes

With your configuration, the stationfinder device assumes the predicted energy consumption at the time of entering the network is sufficient to terminate the route. However the battery is very close to empty at arrival so the rescue action is triggered. In order to make the vehicles charge and arrive safely raise the device.stationfinder.reserveFactor parameter (a value of 5 makes all vehicles head to the charging station).

 

Nonetheless I see the stationfinder device decision logic can still be adjusted a bit. Currently the emptyThreshold parameter is not taken into account for deciding whether to charge or not but actually should.

 

Best regards,

Mirko

Hi,

 

The stationfinder devices are not working, all EVs can't be rerouted to the CS on lane E0_0. And there is no charging record showing in battery.out.xml. Instead, all the EVs are in rescue mode and removed due to the low battery. I have added the battery and stationfinder device in the vType file. Can anyone help me with this? 

 

Best,

Haotian
