Range anxiety — the fear of running out of charge — is one of the biggest concerns for prospective EV owners. But what actually happens if you do run flat? And how worried should you be?
The Short Answer
Running out of charge in an EV is similar to running out of petrol: the car stops and you need assistance. However, it's extremely rare because:
What Actually Happens When an EV Runs Out
The Warning Phase
Long before you run out, your car will:
When It Finally Stops
If you ignore all warnings and the battery reaches 0%:
Important: Unlike running out of petrol, there's a small reserve. The car shows "0%" but retains enough power to run lights, hazards, and locks for a short time.
Can It Damage the Battery?
Running to 0% occasionally won't cause permanent damage. Modern battery management systems (BMS) prevent true complete discharge. However:
How Rare Is It?
Extremely rare. Data suggests:
| Source | Finding |
|---|---|
| RAC breakdown data | <1% of EV callouts are for flat batteries |
| Tesla data | 0.03% of journeys result in running out |
| AA statistics | More petrol cars run out of fuel than EVs run out of charge |
Why it's so rare:
What to Do If It Happens
Immediate Steps
Your Options
1. Roadside Charging (Some Breakdown Services)
2. Recovery to Nearest Charger
3. Emergency Mobile Charger
4. Very Slow Recovery Charge
Breakdown Cover for EVs
Make sure your cover includes EV-specific features:
| Provider | EV Features |
|---|---|
| RAC | Mobile charging units, EV-trained patrols |
| AA | Recovery to charger, EV knowledge |
| Green Flag | EV recovery, training program |
| Tesla | Own roadside assistance included |
Tip: Check your breakdown cover specifically mentions EVs and charging assistance.
How to Avoid Running Out
1. Plan Ahead
Before long journeys:
2. Trust the Range Estimate
Modern EVs are conservative with range predictions:
If the car says you can make it, you almost certainly can.
3. Don't Ignore Warnings
Your car gives you many chances:
4. Know Your Charger Network
| Charger Location | Typical Availability |
|---|---|
| Motorway services | Every services has chargers |
| Supermarkets | Tesco, Lidl, Sainsbury's, Morrisons |
| Shopping centres | Most have EV parking |
| Town centre car parks | Increasingly common |
| Hotels | Many offer guest charging |
| Pubs/restaurants | Growing network |
5. Adjust Driving in Emergencies
If you're running low:
Dropping from 70mph to 60mph can increase range by 15-20%.
6. Use the Car's Features
Most EVs have:
Common Scenarios
Scenario 1: Motorway Journey
You're driving on the M1 and battery is lower than expected.
Solution:
Risk level: Very low — chargers everywhere.
Scenario 2: Rural Area
You're in the countryside with 15% battery and no chargers showing nearby.
Solution:
Risk level: Low-medium — requires awareness but manageable.
Scenario 3: Unexpected Traffic Jam
Stuck in traffic with battery draining.
Solution:
Risk level: Very low — traffic jams don't drain batteries quickly.
The Psychology of Range Anxiety
Most EV owners report the same experience:
| Timeline | Feeling |
|---|---|
| Before buying | High anxiety about range |
| First month | Some anxiety, over-checking |
| After 3 months | Confidence growing |
| After 6 months | Rarely think about it |
| After 1 year | Anxiety completely gone |
Why it fades:
Summary
| Question | Answer |
|---|---|
| What happens if I run out? | Car stops, you need recovery |
| Is it damaging? | Minor, if not repeated frequently |
| How common is it? | Very rare (<1% of breakdowns) |
| Will breakdown cover help? | Yes, most cover EV recovery |
| Should I be worried? | No — far less likely than running out of petrol |
The bottom line: Running out of charge is theoretically possible but practically very rare. Modern EVs make it difficult to run flat accidentally — you have to ignore multiple warnings and bypass the car's safety systems.
Most EV drivers never experience it. After a few months of ownership, range anxiety typically disappears entirely. You'll develop routines, learn your car's capabilities, and realise that charging infrastructure is now comprehensive across the UK.
The fear is understandable before you switch. But ask any EV owner: it's almost never a problem in real life.
