Northbound isn’t open yet, as far as I could see... I used Warwick northbound instead on Saturday morning, which was great - lots of stalls and super fast (350 miles/hr charge rate!) It’s in a prime location there, so they may have a problem with ICEing...
Stoke/Keele services southbound could do with more chargers - I got the last space when I arrived there yesterday afternoon, and the station was obviously strained; only a 90mi/hr charge rate for the first 10 minutes, which went up to about 160 after the MX next to me left.
