I just returned from a two week drive from Minnesota to the East Coast, including New York State, New York City, Boston, and Maine. The car was a Mercedes EQS580. I've had it for six months now, but until two weeks ago, I had only charged it at home.
Aside from seeing some old friends, I wanted to understand how feasible it was to travel charger to charger. Here's what I learned.
Mercedes Isn't a Tesla
It can't use their network. Nobody else can. It's a closed network, except in Europe where the EU has forced them to open it up. Tesla is talking about doing that here in the U.S. Talking.
A Charger Is Not A Charger
They vary from recharging a vehicle in about 45 minutes to several days. Fast Chargers are essential and there aren't many Charger Stations and they often have broken chargers.
The Apps Are A Challenge
Every network has its own app. Parts of each work.
The Charging Networks are Primitive
On my route through Chicago, i used ChargePoint and Electrify America. There were a lot of EVgo chargers in the Chicago area, but I didn't try them. I should have.
Electrify America is owned by VW and has Siemens as a major investor. Around $2.5billion invested so far. More coming. It's fallout from the settlement with the U.S. over Dieselgate. Their support is good.
Plan Ahead
There are so few chargers that you need to know before you go. Several times, my range was in the 20's before I could get to a fast charger.
Bring A Book
My "quick" charges were about 40 minutes. This turned out to be no problem. You meet other people who are in the same boat, learn from them, find something to eat, and walk a little.
Plugshare Helps
It's an app that another fellow charger recommended and it's good. Oddly, you have to enter your trip first in a desktop browser.
GPS Is Good
On Google Maps and on my car's map, you can find chargers. It's awkward but helpful. On Google, you just search for EV charger. On the car, the map has a search window with a EV Charger icon.
Walmart Is Your Friend
Electrify America has the largest fast charger network and they have a partnership with Walmart.
Look Carefully
The chargers are all over the place and sometimes hard to find. Plugshare has pictures. Google sometimes can direct you there.
It was sold to EVgo last year, so its cross system approach may go away.
Bottom Line
It works, but it's not very reliable or easy. It reminds me of the early days of the software business when software generally didn't work well.
If EV's continue to gain market share, the charging networks will have to expand rapidly.
