For a road trip with fast charging, the results aren't that surprising. Maybe not common knowledge, but the relatively high price of using fast chargers isn't new news. The costs of supplying such amount of electricity in a short time aren't cheap, and they don't sell snacks and drinks to help support the operation like a gas station.
Most people aren't using fast charging as their sole source, or even the major source, for EV fueling. Most of it is slow charging at home for maybe a third of the rate. The infrastructure for that for those without such access is lacking, that does need to be addressed.
One of the presenters mentions the costs rose again since filming. I believe ionity charge £1 per kWH now, so add another 45% to the total cost.
I asked my boss about installing a charger, his energy is capped for a year or so but then goes up 400% to the same as what the most expensive chargers cost you. It's kinda annoying this has occurred in the year I'm actually considering an EV.
In the US, utilities will charge what are referred as demand fees. These kick in when monthly usage goes over a set limit, or if the immediate draw goes over one. Fast chargers trigger these. Even the slower ones. Some of the early installed ones here had there rate throttled down to 40kW or less to avoid those fees.
I think these charger fees will come down some in the long term. Part of the price is the overhead for the less used units. More EVs means better utilization of those. Until then, an EV gives you more options in terms of fuel sources than for an ICE.
I was just thinking that I lucked out when my wife said no to the diesel Cruze. The better fuel economy would likely not cover the $2 difference in fuel today.
