The eco charge mode is a mixture of both green energy and energy imported from the grid. Eco mode minimizes the use of grid power, generally taking advantage of cheaper rates overnight, but can also charge using 100% green energy. Essentially giving you the ability to charge up your car for free! The charging power is continuously adjusted in response to changes in generation or power being used elsewhere in the home.

If the surplus generation drops below 1.4kWh, some power will be drawn from the grid to top it back up.

Eco+ charging is very similar to eco charging in that it can utilize power from the grid or your own power source. However, the charge power is continuously adjusted in response to changes in generation or power consumption elsewhere in the home. Your electric car charging will pause if there is too much-imported power, continuing only when there is surplus free power available.

In fast mode, your vehicle will be charged at maximum power. This power can come from a renewable energy source or simply from the grid. The cost of charging an electric car also depends on numerous factors, including mode and the car itself.

If you don’t have solar panels or wind generation, zappi will charge just like an ordinary Mode 3 charging point.
