Range anxiety is a common concern for new EV owners. But what actually happens if you do run out of charge? Here's the reality.
First: It's Very Rare
Running out of charge is uncommon because:
Studies suggest EV drivers run out of charge far less often than petrol drivers run out of fuel.
What Happens as Battery Gets Low
Warning Stage (15–20%)
Your car will:
Low Battery (5–10%)
Your car will:
Very Low (1–5%)
Your car will:
"Empty" (0%)
What "0%" actually means:

What to Do If You Run Out
Step 1: Don't Panic
Running out of charge is inconvenient, not dangerous:
Step 2: Call for Help
Breakdown cover options:
| Provider | EV Coverage | Notes |
|---|---|---|
| AA | Yes | Can charge or recover |
| RAC | Yes | Mobile charging in some areas |
| Green Flag | Yes | Recovery to nearest charger |
| Tesla Roadside | Tesla only | 24/7 support |
| Manufacturer cover | Check your car | Often included for first years |
What they'll do:
Note: EVs can't be towed conventionally (wheels must be off the ground) — flatbed recovery is standard.
Step 3: Prevent It Next Time
After the experience:
Mobile Charging Options
AA/RAC Mobile Charging
Some breakdown providers now carry mobile chargers:

What About the 12V Battery?
EVs have two batteries:
If the 12V battery dies:
Note: A flat traction battery doesn't immediately drain the 12V, but leaving an EV unplugged for months can cause 12V issues.

The Honest Truth
Running out of charge:
The real lesson: After 3–6 months of EV ownership, you'll know your car's range intimately and running out will seem as unlikely as running out of petrol felt before.
Don't let fear of flat batteries prevent you from enjoying electric driving. The rare inconvenience of running low is vastly outweighed by the daily convenience of starting every morning with a "full tank."
