There is no single right answer to how often you should charge an electric vehicle at home. The answer depends on how far you drive each day, how large the battery is, and how much range you want available when you need it. For most drivers, the better question is not whether to plug in tonight, but whether you have enough charge for tomorrow.
Charge to match your daily driving
Start with your typical daily distance. EVs vary, but a round number of about 3 miles per kWh is a useful starting point for estimates. At that rate, a 40-mile day uses roughly 13 kWh from the battery, and charging losses add a little more on the way in.
Now compare that to the battery. A 60 kWh battery holds far more energy than one day of ordinary driving. If you drive 40 miles a day, you could go several days before the battery needs a full recharge. Many owners plug in every night out of habit, even when they use only a small part of the battery. Plugging in every night is convenient, but it is not required for most daily routines.
A simple way to decide
- Check the state of charge each evening on the car's screen or in its app.
- Estimate how much driving you have planned for the next day.
- Charge enough to cover that day plus a buffer, instead of charging to full by default.
- If the car will sit unused for several days, charge it to the amount you expect to need rather than to the top.
- Avoid letting the battery run close to empty as a routine. Keep a buffer for detours and unexpected trips.
Consider the charger's speed
Charging time is roughly the energy you need divided by the charger's power. Replenishing 13 kWh at 9.6 kW takes a little over an hour, before losses. The same energy at a slower charger takes longer, so a slower setup means you need to plan further ahead. Your car's onboard charger also limits how fast it can accept AC power, so a more powerful charger does not always mean a faster charge.
Seasonal and occasional changes
Your habits may change with the seasons. In cold weather, batteries deliver less range, and cabin heating takes energy, so you may need to charge more often. Long trips, visitors, and busy weeks also change what you need. Reviewing your usage once a month helps you spot these patterns before you run low.
How this applies to EVIQO chargers
EVIQO chargers are 240V units with a 25 ft cable. The 40A (9.6 kW) option adds about 38 miles of range per hour of charging, and the 48A (11.5 kW) option adds about 46 miles per hour. For a 40-mile day, a 40A charger needs roughly an hour of charging, so a short overnight session covers it. Because you only need to charge as often as your driving requires, a charger that fits your routine is useful whether you plug in daily or every few days. All EVIQO chargers come with a 3-year warranty, and a 4-year extended warranty is available for an additional charge.
