Free charging

Drove my boat off to the inflatable boat doctor about 150km away. Weather has been so fantastic throughout April that I have always been able to charge the car for 'free' from the PV.

Today with the warm weather, I should have been able to do the 300km round trip without needing charging, but it requires a gentle right foot & preferably not 80% unlimited speed and relatively quiet Autobahn. 

However, the company EnBW who have the largest electric vehicle charging network in Germany, had given me a €10 voucher which expires at the end of the month.  As EnBW is probably my least favourite charging network, and not just by me, I wasn't going to let this offer go. It didn't even require a minimum charge. Sadly I hit the STOP button a second too late & ended up paying €0.18c.
