Sunday February 18, 2018 EV Corridor Analysis Tool Earlier this week I received a press release from the Georgetown Climate Center announced the availability of an electric vehicle (EV) corridor analysis tool developed by M.J. Bradley & Associates.  This tool is designed to allow input from EV drivers about potential locations for DC fast charging stations that will serve major corridors in the North East from Washington DC to Main. 


The tool opens into a visualization map which shows the main corridors and has dots indicating which type of fast charger is available.  A dark green dot indicates locations that have both CHAdeMO and SAE connectors.  Light green dots indicate SAE only.  Light blue dots show sites that have only CHAdeMO.  Purple dots indicate sites that have Tesla and CHAdeMO.  The larger the dot the more charging ports there are at the site.


The first thing I noticed is the lack of Tesla charging locations.  The map only shows locations that were within 5 miles of a major corridor and I thought that might be the reason.  I took a look at Tesla's supercharger map and it was clear that they had charging locations along many of the area's corridors including many locations along interstate 95, the main north/south corridor.  It appears that by default, this map only shows Tesla locations that also have CHAdeMO chargers.  There is a button labeled layers which when pressed produces a drop down menu, and one of the selections there is Tesla charging locations.  If this option is checked then a little red T appears to denote the location of Tesla superchargers. 
The map could be useful for people who  want to see what charger options you have if you are travelling in this area as it shows just chargers located near the main routes so you don't have to deal with lots of chargers not near the freeways as you would if you used something like plug-share.  If you click on one of the dots you  get a pop-up showing information about the site.  I did notice that some of the entries showed the network the charger was connected to but many did not meaning that some additional research would need to be done to make sure that a planned charging stop was actually usable


The layering also allows other details to be added to the map including highlighting stretches of the corridors that have heavy traffic volume and showing areas that exceed EPA standards for Ozone.  There is even a layer that adds pop-up information on traffic volume when you click on one of the highlighted corridors.  You can then click on the Zoom and it will take you to a close-up of the area of road you clicked on.  Pressing the "-" button the map zooms out a little and allows you to look at a detailed plan of the nearest exit.

Using the visualization map for trip planning is not the intended use of this tool.  It is actually intended to be used by EV drivers to make recommendations on the desirability of locations where new chargers can be added.  When the tool is downloaded it is supposed to load information into an excel spreadsheet and allow the EV driver to alter parameters.  This didn't happen when I downloaded the tool so I'm not sure how well this will work.


For those that want to give this a try the tool can be downloaded from http://www.mjbradley.com/analytical-resources.  Registration is required and is free.  According to the website the tool runs best in a Microsoft Windows environment.
