I have had my M3 SR+ since August and have done numerous long journeys all with Superchargers along the route. Yesterday I headed 68 miles to Brighton, started with 93% finished with 53% in Brighton. It was cold etc. I had time after my meeting and before I left thought I would try a quick top up with the CYC charger in the car park I was in. Downloaded app, plugged in charger...eventually got it started for about 5 secs and then it stopped...and then no matter what I did on the app couldn’t get my cable out of the charger. Had to call them, was first in the queue (according to the message) for 17 mins and then a very nice guy, apologised sent a message to the charger and released me. (Well my cable). He said do try again, I decided not to. So I headed back on my return journey...still no absolutely necessity to charge but consulted Zap Map and thought I would try somewhere off the M23...so Tesco’s near Crawley at three bridges, a whole range of chargers advertised on Zap Map, all out of use due to unforeseen circumstances...so I tried three bridges railway station...pod point...I have pod point at home, so I already had the pod point app and had used one of their chargers before. Got there, there was a free charger or 2. Good news. 3kw. Bad news. And on top of that you need to buy a whole day parking ticket for £7 or so to use it for longer than 20 mins before you get ANPRd..so I of course gave up. I headed home, and got back with about 6% left...slightly less than I would have liked on a cold night. Since yesterday I have studied Zap Map again as to what I would have done if I knew I was going to run out before I got home, for example if it had been 75/80 miles each way. I concluded I would have spent a couple of hours at three bridges charging and suffered a slow and expensive charge. I wouldn’t have risked heading to another charger in another network where I may have needed an RFID card...and there was almost nothing else near my M23, M25, A3 Route - all main roads soon to be buzzing with electric cars. All I can say is thank god I have a Tesla as the many super chargers I have used have been 100% reliable and quick...I have no idea how any one in a different electric car will survive at the moment. Also bring on the Brighton supercharger for my next trip down there!
