Frequently asked questions
Is it cheaper to charge an EV at night?
Yes, on most tariffs. Off-peak night rates are typically 30-60% cheaper than peak daytime rates. A night-timed charge can save $300-700/year on a typical EV.
What is a charging schedule?
A charging schedule tells your car or wallbox when to start and stop charging. Set it to start at night when electricity is cheapest, so the car is full by morning.
Can I charge during peak hours?
You can, but it costs more and strains the grid. If your tariff has expensive peak rates, scheduling charging for off-peak windows can halve your charging bill.
Do smart chargers handle scheduling automatically?
Yes — most smart wallboxes and EV apps let you set a departure time and price cap, and they automatically charge during the cheapest hours.
