Hi all,
Just wanted to get your thoughts and learn more about NA's electrical system.
In Europe it seems like they are able to leverage existing infrastructure to put charging stations virtually almost everywhere. Example articles below:
London is installing electric car charging stations inside lamp posts for street charging
Germany is getting 12,000 new electric car charging stations by converting distribution boxes
Now for the US, it doesn't appear to be as easy (though still possible). One thing Europe has going for them is that everything is virtually 230V/400Y, which means they can have A/C charging and DC charging with no issues. (Hence why you see A/C and D/C charging in a single station a lot).
On the other hand, the US generally has:
120/240 split voltage
120V/208Y
277V/480Y
277V is outside the range for A/C charging. (Tesla did support it before with the HPWC, but from what I read this was too close to the upper range supported by the car), so depending on the lightning system installed you can't just stick in a plug without a step down transformer, driving up cost.
This doesn't matter for D/C charging but it costs a lot more to put in a DC charging box.
So what I'm wondering is:
I kind of wish that Tesla had increased the voltage range supported, but I guess it wasn't worth the increased cost.

So what I'm wondering is:
- When I see streetlamps and/or parking lot lights, how often are they 277 or higher vs a lower voltage?
- Was there a reason why Europe went with a standard where you generally need to bring a charging cable? One advantage with that is you can hide a charge point if you want to and not have a cable always being shown, and the cable locks too.
- Long term do you see any changes to the charging standard or a new tech (cheap transformer?) to make it easier to install EV charging almost anywhere? I honestly don't see us being able to add chargepoints to street lamps.
