What Happens If an Electric Car Runs Out of Battery?

If an electric car runs out of battery, it does not cut out without warning: it alerts you several times, then limits its power so it cannot speed up, and finally stops. From there it needs a small charge at the roadside or a flatbed to a charger, because an electric car should not be towed on its wheels and cannot be push started.

It happens less often than people fear. The AA said that in June 2024 only 1.4% of its electric car call-outs were for flat batteries, down from 8% in 2015, and in most of those cases the car still had a little charge left when the patrol arrived. This guide covers what the car does as the battery runs low, what to do when it stops, whether you can push or tow it, and a worked UK example that turns the last few per cent of a battery into miles.

What happens when an electric car runs out of battery while driving?

The car gives you a staged run of warnings and power cuts before it stops, so you have time to reach a charger or a safe place. Nissan’s owner’s manual for the Leaf sets out the sequence clearly, and it is a useful guide to what most electric cars do.

Stage	What you see	What the car does
Low battery	Low battery light, master warning, “Charge now” message, range figure flashing	Drives normally; the navigation suggests nearby chargers
Very low	Range display changes to dashes	Drives normally, but no longer shows a range
Power limitation	Power limitation light and a “Power reduced” warning	Motor output is cut and speed will not increase
Empty	No response to the accelerator	Stops; it will not drive again until it is recharged

Once the power limitation light is on, the car will not speed up even if you press the accelerator. That is the point to leave a motorway or a fast A-road, not to press on for one more junction. Nissan’s instruction is to stop somewhere safe before the battery is completely empty.

The power fades in steps, and the car tells you at each one. Use the warning stages to choose where you stop: a lay-by, a car park or a side road is far better than wherever the car happens to give up.

What should you do if your electric car runs out of charge?

Pull over somewhere safe, put the hazard lights on and call your breakdown provider. Kia UK gives the same steps: pull over as soon as you can, turn on the hazards, switch the car off and call roadside assistance.

On a motorway, the Highway Code says the safest place to stop is a service area, with lay-bys, emergency areas and hard shoulders as other places of relative safety, though hard shoulders give less protection (rule 275). Running out of charge is a breakdown, so it counts as the kind of emergency for which the hard shoulder may be used (rule 269). Once stopped, use the free emergency telephone or call 999 (rule 277).

If you still have a few miles showing, you have two better choices. One is to drive gently to the nearest charger. The other is to stop somewhere safe before the car does it for you. The AA’s figures suggest many drivers already do this, since most of its “out of charge” call-outs reach cars that are nearly, not completely, empty.

The nearest public charger will usually fit your car. Our guide to whether you can charge any EV at any public charger explains the connectors and the exceptions.

Can a breakdown service charge an electric car at the roadside?

Yes, some can, but only enough to reach a charger. The RAC says its EV Boost vans can give a stranded electric car a 10 mile boost to get it to the nearest charge point. The RAC announced the system in 2019: a generator on the van’s engine feeds the car through an inverter, using the Type 1 and Type 2 connectors that the RAC said then covered 99% of electric cars on UK roads.

Ten miles is a rescue, not a refill. If the nearest working charger is further away, or the car cannot be charged where it stands, it goes on a flatbed to a charger. What you get depends on your provider and policy, so read the wording before you need it, especially if you drive long distances in rural areas.

Most of the AA’s work with electric cars has nothing to do with range. It said in July 2024 that the commonest reasons for electric car call-outs were tyres, wheels and the 12 volt battery, as they are for petrol and diesel cars. Our report on the AA’s flat battery figures looks at the trend in more detail.

Can you push an electric car?

You can push an electric car a few metres to safety only if the car lets you select neutral and release the electronic parking brake, and you cannot push start one. If neutral will not engage, the parking brake stays on and the car will not roll, so do not try to force it.

Push starting is not possible. Kia’s owner’s manual for its electric cars says plainly not to push or pull the vehicle to start it, because it could damage the car or injure you. The AA says cars with automatic transmissions cannot be push started, and that pushing a car anywhere near moving traffic or pedestrians puts everyone at risk.

So if your electric car stops in a live lane, get everyone to a safe place first and leave the car to the recovery service. Pushing it only makes sense on a quiet road, at walking pace, to clear a junction or a driveway.

Can you tow an electric car with a rope?

No. An electric car should be moved on a flatbed or with all four wheels lifted off the road. Kia UK explains why: a petrol or diesel car is towed in neutral, but an electric car has no neutral gear in that sense, and towing it in drive or reverse builds up energy that damages the battery.

That is why breakdown services carry electric cars rather than drag them. The RAC says its vans can lift all four wheels of an electric car off the ground, so it can be recovered without waiting for a separate lorry. If a friend offers a tow rope, say no.

Towing is a different question when the electric car is doing the pulling. Many can tow a caravan or trailer, and our guide on towing with an electric car covers the limits and what towing does to range.

How far can you go on the last few per cent? A worked UK example

The last 10% of a big battery is worth a useful number of miles. Take the Range Rover Electric, which JLR prices from £154,070 for the EV550 Autobiography SWB in November 2026, with a 118.5 kWh usable battery and 372 miles of WLTP range.

EV Compared’s method divides WLTP miles by usable battery capacity for efficiency, prices public rapid charging at 82p/kWh from Zapmap’s October 2026 price index and home charging at 6.5p/kWh, and ignores charging losses (see our methodology). On those inputs:

• Efficiency is 3.14 miles per kWh, so the last 10% of the battery is about 37 miles of WLTP range.
• A 10 mile roadside boost from the RAC is about 3 kWh, under 3% of this battery.
• Ten minutes on a rapid charger adds about 118 miles, because JLR quotes 10 to 80% in about 22 minutes on a 350 kW charger.
• Rapid charging costs about 26.1p a mile, so those 118 miles cost around £30.80. A full battery costs £97.17 at a rapid charger, against £7.70 on an off-peak home tariff.

The lesson is that ten minutes at a rapid charger is worth more than ten times any roadside boost, so stopping early to charge beats running the battery down. WLTP figures are test results, and real range falls at motorway speeds and in cold weather; our guide on how far an electric car really goes on one charge puts numbers on the gap.

Does running out of charge damage the battery?

Makers design their warnings to stop you running the battery to empty, so treat zero as something to avoid and recharge as soon as you can. Nissan tells Leaf drivers to stop somewhere safe before the battery is completely discharged, and, if the power reduced warning appears because the battery is extremely low, to stop in a safe location and contact a Nissan certified electric vehicle dealer. Long-term ageing is a separate question, covered in our explainer on what happens to an EV battery at the end of its life.

If you are buying second-hand, how a car has been charged and stored matters more than one flat battery on the hard shoulder. Our used EV buying checklist covers the battery health report to ask for.

How do you avoid running out of charge?

Charge before you need to, plan longer trips around chargers, and treat the low battery warning as an instruction. A driver who charges at home and starts most days with a well charged battery will rarely see the warnings at all. If you are new to it, our guide on how to charge an electric car covers home, workplace and public charging, and Best Chargers compares home wallboxes.

On a long journey, plan to arrive at a rapid charger with 10 to 20% left rather than 2%, so a broken or busy charger is an inconvenience rather than a breakdown. In winter, allow for a slower charge as well as a shorter range: our explainer on why EVs charge more slowly in the cold explains what is going on.

What it means for choosing an electric car

Running out of charge should not decide whether you buy an electric car, but range should decide which one. Kia UK quotes an SMMT average UK range of 236 miles; a car whose range comfortably covers your longest regular journey, plus a home charger, will rarely get near empty.

If you mostly drive locally and charge at home, a smaller battery suits you and the risk of running out is low. If you regularly cover long motorway journeys or cannot charge at home, choose a car with a longer range and fast DC charging, so a ten minute stop adds a useful number of miles. Whatever you buy, check that your breakdown cover includes roadside charging or flatbed recovery for electric cars.

Our verdict, based on published manufacturer and breakdown service information rather than our own testing: running out of charge is rare, gradual and recoverable. The car gives you plenty of warning, the realistic outcome is a short boost or a flatbed to the nearest charger, and the habit that prevents it is simple, charging well before the warning lights come on.
