So, partly inspired by comments in this thread earlier jr and I hatched a plan whilst at a track day on Friday night to head off for a journey in the wife's EV on Saturday, with no planning whatsoever for charging or anything else, save a few destinations for some sightseeing as the weather was supposed to be good.
Leaving at sparrow fart, with the car fully charged, we headed across Derby way and oop North up the M1 for breakfast in Knaresborough. As luck would have it the car park had a couple of 50kw chargers, so by the time we'd filled our faces with a full English at Marigold's Cafe, charge was back up to 100%.
We then headed off to Whitby, stopping along the way on the Moors for a stroll and to take in the scenery. Arrived in Whitby in time for a fish and chip lunch at Quayside and a stroll along the seafront. Charging infrastructure in the North East is woeful. 50kw chargers are few and far between and the best your likely to find in a convenient location is 7kw. We didn't need to charge anyway, so that didn't matter.
Then we headed further north to Durham, where jr had never been before and I bored him solid for an hour or so showing him all the haunts from my uni days. To try and cheer him up a little, I allowed him to buy us ice creams... Not knowing when the next charge was likely to be I'd left the car charging at 7kw in the city centre. As you might imagine that didn't add a great deal of range at that speed but it's better than nothing.
Then we headed across to Carlisle with the intention of charging on the M6 on the way home where the range indicator suggested we'd need to do a meaningful charge somewhere around Manchester. We decided we needed a pitstop in Carlisle and also replenish our stock of travel essentials (Jelly Babies and Wine Gums). Low and behold there was a 50kw Instavolt charger at the supermarket so hooked up to that. After just over an hour we had enough range to get us home.
Drive back down the M6 and arrived home at about 11pm with 34 miles of range left.
We drove everywhere sticking to speed limits but with my usual heavy right foot. No concession was made to economy, aircon was used all the time. Not once did I even think about the possibility of running out of juice on a journey that has quite poor charging infrastructure.
Had we been able to charge at 350kw where the car can get from 10% to 80% charge in 18 minutes we'd only have needed to charge the once during our 624 mile trip.
