Hi there,
We travelled from Kent to Catalonia in early January in our LR. The infrastructure in France (in our opinion) is not as good as in UK, most of rapid chargers are 50kw, however there are also many 150+kw ones, but these are expensive (around 0,8 euro). Some of them apart form charging per kwh charge you per minute (+ kwh), on the other hand there there are still some free free ones (rapid ones) and a very cheap ones.
It might be worth ordering a charge map card, as for 20 euro it gives you access to many networks across France (and Europe) without paying monthly subscription.

I would personally try to avoid Ionity, as their prices are quite heigh. Freshmile is quite cheap or even free.
It's worth downloading A better route planner, EV navigation and chargemap apps.
We were doing a lot of planning before we left, finding chargers and an alternatives just in case the charger doesn't work (it happened once - the alternative charger was 20 km away and it luckily work and was free) After a while we took bit more of relaxed approach and we only started looking for stops as we were driving, for example we would start looking around 35% charge (it was 'co-driver' task), we mostly used chargemap app to see what's on our way, if it's live, the cost etc.
If you have any cards for charging, it's worth taking them with you. We went to Valencia last week and were able to start a rapid charger in the city (it wasn't possible to start it with an app) with Electric Juice card from Octopus, even though it wasn't listed on the map. One more thing, France has got a lot of "semi-rapid" AC type chargers (type 2), up to 44kw, so make sure to check the type of the connector (CCS) when you are looking for a charging point, not just "current".
All in all, we've done around 900 miles.
