When optimising your charging, ev.energy's smart charging algorithm will always put YOU first. If there is extra flexibility within your charging schedule, then ev.energy will automatically select the best times for the grid and the environment to help you charge cheaper and greener. 

There are four layers of optimisation;

1. Getting your EV charged by your "ready by time"
2. Using the cheapest times for the energy tariff selected in the app
3. When the electricity grid is less congested and;
4. When there is the most low carbon generation available

You're still in full control of your "ready by" time and can "Boost" charge whenever you need to - but remember, Boosting may utilise high-carbon energy at peak prices.
