Cologne's dense network of Aral, Shell, Esso, TotalEnergies and budget JET and STAR stations spreads along the city ring and the A1/A3/A4 motorway box. German fuel prices swing several cents within a single day, so timing matters. EV charging is extensive, with rapid hubs at retail locations and along the Rhine corridor motorways.
Cologne has more charging points mapped than fuel stations, 822 against 244. That is still rare, and it makes this an easy place to arrive on a low battery. See Cologne on the map →
