When Is the Cheapest Time to Charge Your EV at Home?
Learn how time-of-use rates affect home EV charging costs and how to find your utility's cheapest off-peak windows.
Why timing matters more than where you charge
Home EV charging is almost always cheaper than public fast charging — but the hour you plug in can change your cost by 50% or more. Most US utilities now offer time-of-use (TOU) rate plans that charge significantly less during off-peak hours, typically late evening through early morning.
If you charge during peak hours — often late afternoon and early evening — you pay the highest rates even though you're using the same amount of electricity. Gleam's free electricity usage calculator can estimate how much an EV adds to total home kWh before you optimize charging times.
How to find your off-peak windows
Check your utility bill or rate schedule for peak, off-peak, and super off-peak periods. Many utilities also offer EV-specific rate plans with even deeper overnight discounts.
Gleam reads your actual rate plan and usage to recommend the cheapest charging windows for your home — no spreadsheet required.
Solar, batteries, and EV charging together
If you have solar panels, midday charging can be nearly free when production exceeds usage. But overnight off-peak grid charging is sometimes cheaper than discharging a home battery or exporting solar at low net metering credits.
The best schedule depends on your full setup — utility rates, solar output, battery size, and driving habits. Gleam models all of it together.
