This DC fast charging station tells EV drivers when renewable energy is at its peak in the grid – and thus when charging prices are cheapest.

The “Better Energy Charge” station in Sønderborg, Denmark, is owned by renewable energy company Better Energy. (It sits next to the company’s R&D solar park.)

What makes this charging station unique is its dynamic pricing model. It differs from traditional fixed pricing schemes because it incentivizes EV drivers with lower charging prices when renewable energy is at its peak on the grid.

The charging price, which is available the day before, follows the Danish energy spot prices. Similar to a gas station’s pricing signs, the EV charging station’s price board is visible from the road. (Why don’t all EV charging stations do this?)

“We want to encourage people to charge their cars when there is a lot of renewable electricity in the grid by making it cheaper when the sun is shining and the wind is blowing,” said Peter Munck Søe-Jensen, EVP of power solutions at Better Energy.

The Danish company feels its model helps drivers plan in advance to charge their EVs when energy is at its cheapest. Plus, by charging EVs when solar and wind energy production is high, consumers can also increase the probability that they’re using renewable, not fossil fuel-powered, energy.
