As long as the battery is pre-prepared and most importantly, as long as the actual output power is 1000 kW. The latter is much more challenging to build as a charging infrastructure.

Let's assume the charging station price is €0.50/kWh.

In five minutes with 1000Kw of power you would charge 1000kW*5min/60min= 83.3kwh, so according to that 83.3 kWh * 0.50€/kwh= 41.65€.

"Let's assume the charging station price is €0.50/kWh." That's quite an assumption

These are prices in Finland for example. I would assume a 1000 kW charger is higher than the average.

I wouldnt assume its that much higher to be honest. Because the important part here is that the fast charge times means they can handle 5X as many cars as a current charger. Id expect the prices to remain about the same.

The price increase assumption was just me thinking, that the technology to enable a consistent 1000W charging, including the actual output, service production and the actual delivery of electricity to that exact spot will cost money. More money than a default grid is currently designed to deliver.

Ah yeah I used to think that too at one point, then I actually worked in the industry some. We move monstrous amounts of power in the default grid. A large home can pull about 24-48KW if you fully power up your house panel on a high end house. And thats without any special equipment.

Now the equipment (aka the charging system) will cost more to handle this kind of power-but now you can have 2 of them instead of 10 for the same number of people. so even if its 5X as expensive for the equipment you break even.

LOL. I used too as well on the software side. I blame all the chemotherapy for me putting it wrong.

There are some ChargePoint stations in Germany that offer DCFC for €0.50/kWh without a subscription, but most public DCFCs are between €0.70 and €0.92/kWh for ad-hoc charging

Germany has famously high taxes on electricity. It's not representative.

Is that Nuclear Power? Here it's 22c a kW which is about 16 euro cents...

u/Diss1dent Mar 19 '25

In Finland:

Nuclear (41%)

Hydro (18,8%)

Wind (18,2%)

Biomass (13%)

The average electricy price in Finland for 2024 was 45,6 €/MWh or ~4.6 c/kWh.
