This is a shortcoming of the Google operating system, not Volvo. But yes, this is normal behavior and is not good. Everyone’s threshold is different, but I’d personally want to filter to 100kW and above only (there are some ChargePoint spots near me that are 120kW shared) but most of the 100+ are as you found, EA chargers.
At the moment you cannot filter like this (you can in PlugShare). So the best work around is to just navigate yourself to the desired charging location. Even in a Tesla or such, I always suggest pre planning any trip using your app of choice. I like the trip planner in the PlugShare app/web site, but EV Trip Planner and sites like that can be even better. A Better Route Planner is one of the most comprehensive, although the powerful ness of it can be daunting for many users.
FWIW, we’ve taken a few trips already in our XC40 and I’ve trip planned using PlugShare, then turn off ALL networks except for Electrify America, and saved the trip. Then during the drive I can just pull up the saved trip on my phone, and then by voice say “hey google, get directions to ElectrifyAmerica charging station Pittsburgh Pennsylvania” (fore example) and it works great. Food for thought…
