I've had my Taycan for almost a year now and have 14K miles with most of those being long drives/road trips and Electrify America charging stops. One thing that I've noticed from my last big trip is that EA stations are becoming even less reliable and there are more and more cars using them. Especially on weekends.

From EA stations being down to arriving to one where they were doing maintenance on all of them I've been experiencing some minor close calls. In the Southeast where I live the two busiest charging stations near me are in Asheville and Greenville. Both only have 4 stations at a Sam's Club, are difficult to get in and out of, and are so busy that I'm often having to wait to use them.

Last month I arrived in Asheville to find myself 3rd in line to charge and where others had to wait an hour to charge. It didn't help that an EQS owner decided to leave his car plugged in and was idling for more than 2 hours blocking the charger from being used by others.

This is the problem that I am seeing on the road right now:

- EA stations are not reliable with some units not working so the station is basically left with only 3 functional chargers
- Chevy Bolts have doubled in production and at only $25K are becoming more and more common. These cars only charge at a max speed of 55kW so will occupy a charger for much longer than most cars
- Hummer EV's have such a large batter pack that even with a charging speed of 350kW it takes them an hour to go from 20-80% which is much longer than most cars
- Mustang EV's charge at 150kW but then taper to a level-2 charging speed at 80% and greater so uneducated new owners who think that they need to charge above 80% will occupy a charger for long time
- New uneducated owners will charge to above 80% regardless of the type of EV they're driving which again will occupy more time at a charger

On my last trip from Toronto to Atlanta I saw a ton of Chevy Bolts, Cadillac Lyriq, Mercedes EQS and EQB (or whatever their new SUV model is), VW ID's, etc. basically they are more and more cars using the network and new installations are far and few in between at least on the East Coast.

EA's charging network is not keeping up with the amount of new EV's hitting the streets and unfortunately there are no other companies coming out with DC fast chargers above 150kW to help keep up with the demand. And as more and more EV's hit the street at some point there will be enough of them that we'll lose the benefit of driving in HOV lanes and toll roads for free.

As somebody who bought EV's (we also own a Telsa and a couple of V8 cars) not to save the planet but because of the way they drive I would love to see a new administration slow down the transition of forcing everybody to move to EV's and rather make electrical vehicles an option to those who prefer them. Yes, that's me being selfish but that's what the majority of the population seem to want anyway.

Interested in hearing other people's experiences on the demand on the current charging infrastructure as well but that's my two cents.

I agree 100% with this. Living in Dallas and about to make a road trip to Atlanta next month. I have to go out of my way a couple of hours due to lack of chargers (zero) on I-20 in LA & MS. I also own a Tesla and have watched the super charger network grow leaps and bounds attempting to keep up with demand. I'm very worried EA or others are going to be able to keep up with the same level of build outs.

hopefully Tesla Supercharger network becomes CCS compatible in the next 18 months - that will help greatly…

As much as I like my panoramic roof, I would have much preferred to have high-efficiency solar cells covering the hood and roof of the Taycan so that you could be re-charging while driving or parked in the sun.

the issue with EA and other suppliers is two fold.

keeping the chargers operational has been an issue but is resolved by hiring more techs to service the units.

the bigger issue is that the charging infrastructure is not keeping pace with the numbers of EVs hitting the roads.

this problem is not easily solved because the siting of the charging units can be problematic.
local electrical infrastructures are sometimes unable to supply the levels of power the chargers need, and the general cost of placing the units is hampering expansion of the charging network.
in addition the math doesn't really support the expansion of the charging network.

unless the number of L3 charging locations can be significantly expanded we will all be impacted by charging issues when travelling out of the car's range.

even if the entire roof was made of solar panels the amount of charge that it would generate is minimal at best and makes little sense.

It could avoid the draining of the 12 volt battery though!

One of the Prius models had an option for this. The roof is nowhere like big enough to dent the requirement of the traction battery but it helped with the 12V and cabin ventilation iirc.

Just because it charges slowly doesn't mean it is illogical.

When I go on vacation, I will frequently leave my car without driving it for days. Why wouldn't it be a good idea to have it charge that whole time (and while driving)?

I appreciate that it is not efficient right now, but I'm hopeful that the efficiency will improve over time. Now, if it is both very expensive and very inefficient, then I appreciate that one or both parts of that equation would have to change before we would want it to be deployed.

I agree 100%. When I first took my brand new Taycan on a road trip last year, the EA chargers on I-5 were working and empty. Never had to wait and always got a charge. Fast forward to last week and half the chargers are unavailable and there are Bolts and Hyundai’s and Mustangs all waiting to charge. With all the tax subsidies these car makers received, they should have been required to build out the infrastructure along with VWAG instead of just piggybacking on their network. It’s made driving with the Taycan away from home super unreliable.

It's not a matter of efficiency of the solar panels. Even if your entire roof and hood has 100% efficient panels, the total energy collected would be minimal compared to the need of the Taycan. I'm just making up numbers, but let's assume you live somewhere sunny and could average 100W between different weathers, nights and days, shades, garages, etc. That's 2.4KWh per day, or 12.5 minutes charging your standard Taycan (7.5 minutes if you have the 19.2KWh charger and matching EVSE), or 35 seconds of charging at a DC charger (assuming 250KW).

Another way to put it, there isn't enough sun energy shining on your car for make it worth while.

That is pretty much what they are good for - ventilating the cabin when it's hot outside due to sun shining. Here in the US we have similar, solar powered ventilation fans for attics in some homes.

Yea, but compared to the large battery, it doesn't make significant impact. Your 12V battery can be topped off for many days from the HV battery, the energy needed for that you regain in seconds at a DC charger. The cost and complexity added to the system is just not economical. Heck, the added weight itself would make your EV use more energy for every day driving, offsetting some (if not all) of the gain.
