Off-peak charging refers to the practice of charging EVs during periods of lower electricity demand, typically during nighttime hours. UK regulations encourage off-peak charging as a way to optimise the use of the power grid. By incentivizing EV owners to charge their vehicles during off-peak hours, the regulations aim to avoid excessive strain on the grid during peak demand times while also promoting cost-effective charging for consumers.
