In fact you may want to make this even more fuzzy, checking for either
tag. And
That might conflict with a nearby non-Tesla charger.
use name:Supercharger not name=Supercharger.
What's the difference? I already use a case-insensitive substring search
for
supercharger.
OSM mappers will often change things like a name tag. While it is
possibly
nobody will ever mess
with the data you left in OSM, but chances are periodically someone will
hand edit the nodes
you left.
Here's a supercharger with all the bells and whistles mapped out[1].
* The charging problem is all about current. The big old transformer that
supports a Tesla DC station was added to the north of the screen wall.
* The original node form Tesla was in the walled area.
* I use a single node for all the chargers that I have mapped including
Tesla. If a charging site has limited amps going to the vehicle, then the J
connector style can require a long time for a partial charge. Hence, this
is not like a gas station where a single node is good enough. For example,
an EV charger may be tied up for four hours in low amp settings. Tesla is
changing the game with a 10 minute charge time.
* The real address on the site is 444 South Watson Road[2]. The addressing
authority did not send the address to the USPS so you will not find 444 as
a valid USPS address via address correcting software. 444 is a valid
Buckeye AZ address for emergency calls or for the utility company. If the
address was submitted to USPS, then you'd receive a code saying that 444
was a valid address along with additional information saying that the USPS
will not deliver mail to that site. 444 is on the south side of the walled
area.
* The 416 address is for the Carl's Jr. I have not added that photo to the
OSM wiki yet. I am not sure if it would help. Perhaps Carl's Jr. is the
operator/sponsor of the charger? If so, then that would be a savvy
business move. Sponsoring the Tesla charger may help Carl's Jr. compete
with the truck stops to the west of the location. USPS would deliver mail
to the 416 address.
* I put the Buckeye Supercharger name on the industrial landuse that I
added to cover the switching cabinets. All the addresses and names would
help someone find the location. Nominatim has already picked up the
information.
* I used Key Pad Mapper 2 to record all the reference numbers on each
terminal. It looks like there is significance to the As and Bs in use[3].
* I used an idea that I picked up from Bryce on his Duro repair stations.
I changed the original source tag to website. I added source as survey.
Let's say that you program sets the source tag to auto or the program's
name. If a mapper takes the time add the detail, then your program could
use the survey tag as an indicator to discontinue the updates to the tags.
* Feel free to hack and whack on the nodes that I created. It won't hurt
my feelers and I won't stop mapping if you do. The wiki page is a mess
right now[4]. I have found that it is a confusing topic to get straight as
I am not an EV vehicle driver. I think there needs to be a US or North
America section of the page that has a focus on what is used here. You all
can hack and whack on the wiki page too.
* One of the problems is that in a pinch, a regular RV socket can be used
to charge the vehicles. That may mean that RV and EV tags could merge some
day.
* I'd encourage you to continue your efforts. Once you have the Tesla
stations done, then you can try your hand at all the other chargers. I
added a great deal of detail for a couple of SemaConnect Network chargers.
I personally wouldn't do that in the future. Having an assisted editing
system like what your are trying to develop would be a great help to
enhance limited data that a mapper might include. All the other chargers
require some sort of membership to a network unless the government is
pushing a free one[5]. Such a deal! Spend $30K + on an EV and get free
parking at a basketball or baseball game. ;-)
