Dynamic #EV charging prices, following the spot market, and available to all - including direct payment with bank or credit card, without ‘fees’. A big ‘Bravo!’ for enercity and EV-Pay for showing what is possible in Germany, despite all the ‘Eichrecht’ hurdles.

Stündlich wechselnde Ladepreise: Enercity und EV-Pay führen dynamische Ad-hoc-Preise ein - electrive.net
Der Strompreis am Spotmarkt schwankt, an Ladesäulen sind heute aber starre Festpreise die Regel. In Hannover ist das bald anders: Enercity und EV-Pay starten

Can slow recombination in ordered superconductors explain the excess quasiparticle population?
An excess density of quasiparticles is widely observed in superconducting films. This excess causes performance degradation in a variety of superconducting devices, including decoherence in qubits. In this Letter, we evaluate the hypothesis of [1] that the quasiparticle excess is caused by anomalously slow recombination at low quasiparticle densities due to localization in sub-gap states. We probe the density of states in aluminum and niobium films using current-voltage measurements of tunnel j…
