Quick Answer: How Long Does a Charge Last?
A full charge on a modern electric car lasts between 200 and 400 miles depending on the model, battery size, and driving conditions. The EPA-rated range for popular 2026 models spans from roughly 240 miles (base Hyundai Ioniq 5) to 402 miles (Lucid Air Grand Touring). In real-world driving — highway speeds, moderate climate — expect to use 70% to 85% of the EPA sticker number. A 300-mile EPA car typically delivers 230–260 miles before you need to plug in.
The question "how long does a charge last on an electric car" doesn't have a single answer because range depends on battery capacity (measured in kWh, or kilowatt-hours — the total energy stored), vehicle efficiency (how many miles per kWh), and how you drive. Let's break down the real numbers.
Understanding EV Range: EPA Sticker vs. Real-World Miles
The EPA range figure on a window sticker is a laboratory-derived estimate that blends city, highway, and temperature-controlled conditions. It's useful for comparing vehicles but rarely matches what you'll see on the road.
| Vehicle | Battery (kWh usable) | EPA Range | Real-World Highway | Real-World Cold (30°F) | Efficiency (kWh/100mi) |
|---|---|---|---|---|---|
| Tesla Model Y Long Range | 75 kWh (NMC) | 320 mi | ~270 mi | ~230 mi | 25 |
| Hyundai Ioniq 5 (RWD Std Range) | 58 kWh (NMC) | 240 mi | ~200 mi | ~175 mi | 26 |
| Chevrolet Equinox EV 3RS | 85 kWh (NMC) | 319 mi | ~265 mi | ~225 mi | 27 |
| Ford F-150 Lightning (Ext Range) | 131 kWh (NMC) | 320 mi | ~250 mi | ~210 mi | 42 |
| BMW i4 eDrive40 | 81.5 kWh (NMC) | 301 mi | ~260 mi | ~220 mi | 27 |
| Lucid Air Pure | 88 kWh (NMC) | 419 mi | ~350 mi | ~300 mi | 22 |

Why the Gap?
Three factors consistently reduce real-world range below the EPA number:
- Highway speed: Aerodynamic drag increases with the square of speed. Sustained 75+ mph driving cuts range 15–20% versus mixed conditions.
- Cold temperatures: Below 40°F, battery chemistry slows and cabin heating draws 2–5 kW continuously. Expect 20–30% range loss at 30°F, and up to 40% at 10°F or below.
- Elevation and payload: Mountain passes, heavy cargo, and roof boxes add energy demand that the EPA cycle doesn't model.
How Battery Size and Efficiency Determine Range
Range is a function of two variables: how much energy the battery stores (kWh) and how efficiently the vehicle uses it (miles per kWh or kWh per 100 miles).
The formula is simple: Usable battery kWh × vehicle efficiency (mi/kWh) = approximate range.
For example, the Tesla Model Y Long Range has roughly 75 kWh of usable capacity and achieves about 4.0 mi/kWh in mixed driving: 75 × 4.0 = 300 miles. The Lucid Air Pure's class-leading efficiency of ~4.5 mi/kWh combined with its 88 kWh battery yields over 400 miles on paper.
Battery chemistry also matters. Most 2026 EVs use NMC (nickel manganese cobalt) cells, which offer high energy density. Some models, including the standard-range Tesla Model 3 and certain BYD vehicles, use LFP (lithium iron phosphate) chemistry. LFP batteries are heavier and hold less energy per kilogram, but they tolerate daily 100% charging without degradation concerns and typically cost less to replace.
EV Range vs. Gas Car Range: A Fair Comparison
| Metric | 2026 Tesla Model Y LR | 2026 Toyota RAV4 (Gas AWD) |
|---|---|---|
| EPA Range / Tank Range | 320 mi | ~435 mi (14.5 gal × 30 mpg combined) |
| Real-World Highway Range | ~270 mi | ~375 mi (14.5 gal × 26 mpg hwy) |
| Refuel/Recharge Time | 10–80% in ~22 min (250 kW DC) | ~5 min at gas pump |
| "Refuel" Cost (Full) | ~$10–14 home / ~$28–36 DCFC | ~$48 (at $3.30/gal) |
| Annual Fuel/Energy Cost (15k mi) | ~$540 (home charging) | ~$1,650 |
Gas cars still hold a raw range advantage, especially for long road trips through areas with sparse charging. But for the 80% of drivers who travel fewer than 40 miles round-trip daily, a 250-mile EV charge lasts several days — and home charging means you start every morning "full."
