In general, the best time to use an EV charger at home is during off-peak hours when the demand for electricity is low and energy prices are cheaper.
Off-peak hours are typically between 12 am to 7 am or 11 pm to 6 am, depending on your energy supplier. During these hours, energy prices are typically lower, and the grid is under less stress from high demand.
By charging your EV during off-peak hours, you can take advantage of lower energy prices and potentially save money on your energy bill.
