I ordered a DKV card. I also read about other options, but I've had very good experiences with DKV. In fact, we still use this card for our Octavia, enjoying attractive fuel prices compared to others, such as Routex. I linked the card to the app, checked the prices and unlinked the card almost immediately. Unfortunately, when it comes to charging electric cars, it's simply more expensive. It still pays off most to use the Elocity and Greenway apps, and to do the rest of the charging ad hoc, e.g. with a QR code. A shame, because I love having 1-2 consolidated invoices a month rather than one for every single charging session.
Recently I came up with the idea of driving to the cheaper charger at the Lidl in Stary Konik, but in the end I changed my mind. Owning an electric car, I don't want to drive slower just to save energy. I want to travel within the rules, optimize my time and use motorways whenever I can. Time is what matters most to me.
On the route to the Lidl in Stary Konik, 80% of the way is motorway, which of course affects energy consumption. One way it comes to 4 kWh (3.97 kWh to be exact). Maybe on the national road the consumption would be closer to 3 kWh, maybe even less – I'll probably verify that someday. But back to the calculations: if one way takes 4 kWh, then there and back comes to about 8 kWh.
The 50 kW DC charger at Lidl costs 1.99 PLN gross per 1 kWh. For comparison, the 60 kW DC charger in Mińsk costs 2.39 PLN gross per 1 kWh. The difference is 40 grosz per 1 kWh. The cost of getting to Lidl, assuming I charge there, is 15.92 PLN gross. To break even, I'd have to add 39.8 kWh for Lidl to turn out cheaper. In reality, charging that much energy while losing time doesn't make much sense. 40 kWh is more than half of a 77.5 kWh battery, and we rarely charge the battery by more than 50%. Losing 40 minutes to save a few złoty when charging in the 10-80% range? The price difference is less than 10 PLN. And that's how I mathematically debunked my own idea. :)
Luckily, any moment now they'll launch the charger at the Lidl in Mińsk, which will resolve the dilemma (unless Budimex decides to cut its prices then :)).
It's worth stopping at the Lidl in Stary Konik if we're coming back from Warsaw, are low on energy and need to do some shopping. It's not far from the exit, so then you can easily use DC or AC charging. 😊
