sell to Siemens is an overstatement - Siemens has/will take a minority interest in EA - not sure as to why - but that is what is happening.

FWIW: you will never see your car charging at 350kw, I believe it is goverened to 270kw and you'd only see that speed if the car is very low SOC, battery pre conditioned and it will taper real quick. if you can get over 200+kw for the first 50% of SOC you are doing well.

Thanks for the reply, the last time I looked I did not find anything, this time I got a number of videos. I do not know what I did wrong, but the videos were interesting to watch. Once again, thank you

I did a recent presentation on EV chargers at a technical industry event. I learned and presented a few things:
1. They are supposed to be designed to avoid puddles where you step. This is mostly for perception, as they should be well grounded. However, defects and stray currents will be hazardous, so puddles should be avoided.
2. Charging speeds will be reduced if other cars are charging from the same electrical equipment. The local power equipment may only be able to supply a limited amount of power. If your car isn't limiting the power charge rate, then the charger is limiting the charge rate due to other circumstances.
3. The industry is all over the place on testing the final installations. Many installations do not test the affect of full load charging (all chargers delivering full load). So they don't really know if they work when all charges are in use. They will likely just provide an awful charge rate to all cars connected.
4. Testing all the low voltage functions (monitoring, payment systems, client communication) is also poor and the service is inconsistent.
Based on what I have learned, I have extremely diminished expectations on long distance electric travel.

Still plan to use a BEV for all my daily driving and many weekend errands so I’ll use an EV for >90% of all my miles, but all longer trips will still be in an ICE, usually my 991.2 GT3.

I was already planning on swapping my Tesla M3P for an electric Cayman when that Cayman comes out in 2 years, but this news makes my Tesla even less desirable by the end of this year.
I think Tesla will regret opening up their charging network as this will make Tesla’s own cars much less desirable.
Porsche already makes a better BEV. So if any driver can utilize the Tesla network, the discerning driver will choose a Porsche BEV, and the Tesla supercharger network.

Here's a great article on the charging infrastructure.
And for those not believing ...this is what happens when one runs of electrons.
Electric cars are doomed if fast charger reliability doesn’t get better

Agree. I don’t plan to drive an electric car on long distance trips in the future. Will always keep an ICE for that.

For those of us who can afford multiple cars, that works well. When we travel long distance, I do a cannonball run, and stops are short and efficient. Half hour or more stops will never happen and sharing the driving allows long distance in a single day. I need 400 miles of range at a steady 80 mph and a full charge in no more than 15 minutes...tops. Does that car exist with an all electric powertrain?
When EV road tripping in an optimal fashion, one doesn't do a full charge at intermediate stops. Takes too long. That last 10-20% takes an eternity.

I definitely would not want to own only an EV as my one and only car unless I lived in a very EV friendly area, and I didn't enjoy weekend trips. But neither of those apply to me, so I think it makes more sense to buy a reasonably priced EV as your daily drives that does 90% of your miles, including errands and other non recreational activities. But you'll still keep one or two ICE for long trips, hauling things, and hauling people.
My Tesla model 3 performance and my 991.2 GT3 are my only cars, and perfect for me.
I'm single, but I would think a good set up for most middle class families would be two inexpensive EVs ( one for mom and one for dad, (if they both work)), and then an SUV for family activities and family trips.
Tiny carbon footprint, charge only at home, lots of instant torque for daily driving, much cheaper than gas, but the family does haven't have to deal with stopping all the time on trips, broken chargers, and inability to tow boats, gear, and travel trailers

Design
Like Tesla, they could have forked out the money to install them themselves (making sure there are no gaps in major routes) and like gas stations around the world they could have design *ALL* the chargers to take credit cards.
