Electrical charging on the road is expensive, because those are fast chargers, and not normal chargers a home would have.
A ~7kw charger you'd install in a home or a business has is relatively cheap wiring electrically, and the stalls are not that expensive.
Rivian adventure network uses chargers that have to output 220kw into the car. This requires significantly higher cost for getting electricity to each stall, the stall needs to be able to handle that much power transfer, and they must be actively cooled (since that much power causes a significant amount of heat). They also require a decent amount of maintenance.
These stalls can cost upwards of $100k per stall for installation.
This is all done so you can charge in ~20 minutes (as opposed to several hours it would take at a normal 7kwh one).
That's why fast chargers cost significantly more. They also need higher profit margins to make back the installation and maintenance cost depending on utilization rates they expect, otherwise installing these chargers doesn't make a lot of sense for businesses.
