Check this out….here’s a great side by side comparison of an Agile v Time-of-use tariff and how Ohme does the hard work in interrogating the pricing to adjust the charge profile to achieve your defined charging goal.
The Time-Of-Use tariff (black line) shows itself as uniform square wave in the first graph, that is a set period of higher cost and lower cost per day. However look at the agile (blue line), particularly 22-24th where plunge pricing occurs hitting -10p at certain point. Some very happy EV drivers using Ohme with an agile tariffs at these moments!
This second graph takes a specific day and how his Ohme chargers executes Nicks defined charging schedule, taking advantage of the agile tariff to deliver his energy requirement at the lowest cost
