@TechConnectify Probably right, but I wonder if fast-charging most EVs is actually too cheap for this to matter — at least for people on long trips who usually charge at home.
For those customers, the experience of the charger and its location — how nice/convenient it is to spend 30 minutes there — is probably more important than whether the electricity costs $15 or $12.
Of course, the bigger the battery, or the more you use DC fast-charging, the more a price difference starts to matter.
