Most EVs let you set a charge limit, which is the percentage of the battery the car will charge to. For daily driving, a lower limit is often enough. Matching the limit to what you actually need keeps the battery in a moderate state of charge, which is generally easier on lithium-ion batteries than sitting at full for long periods.
Why the limit matters
Lithium-ion batteries are generally most comfortable between about 20 and 80 percent. Charging to 100 percent and leaving the car parked there for hours or days adds more stress than a moderate charge. A charge limit lets the car stop at the level you choose, so you do not have to remember to unplug early. The effect builds up over years of ownership rather than showing up in a single night.
Choosing a daily limit
Start with the energy you need for a typical day. As an example, take a 60 kWh battery and a 40-mile day that uses about 13 kWh. A limit of 80 percent holds about 48 kWh, which is far more than that day needs. For most daily routines, a lower limit still leaves a comfortable buffer while keeping the battery at a moderate level.
A few habits work well with a daily limit:
- Use a lower limit on normal days when the next day's driving is short.
- Raise the limit to 100 percent only before a long trip, and plan to drive soon after the charge finishes.
- Avoid leaving the car at full charge for long stretches when you do not need the range.
- Keep a buffer so the battery does not regularly run close to empty.
Understanding the range display
The range shown on your car's display is an estimate based on the current battery level and recent driving. A higher limit increases the range shown, but cold weather, highway speeds, and heating or cooling can reduce what you actually get. Leave margin for those conditions, especially on days when you plan to drive farther than usual.
Where to find the setting
Charge limits are usually found in the car's charging menu or in the manufacturer's app. Some chargers and charging apps offer their own limits as well. If you use more than one method, confirm which one controls the final stopping point so you know what to expect when you return to the car.
How this applies to EVIQO chargers
The charge limit is usually set in the vehicle, so the setting works the same way no matter which EVIQO charger you install. EVIQO offers 40A (9.6 kW) and 48A (11.5 kW) options, which add about 38 and about 46 miles of range per hour of charging. A typical daily top-up on a 40A charger takes one to two hours, so a lower limit still leaves plenty of time within an overnight window. EVIQO chargers come with a 25 ft cable and a 3-year warranty, and a 4-year extended warranty is available for an additional charge.
