One of the most common concerns for drivers considering electric vehicles is simple: what happens if an electric car runs out of battery? It's valid, particularly for those accustomed to petrol cars where running out of fuel feels more manageable.
The good news? Running out of charge in an electric car is considerably rarer than running out of petrol. Modern EVs feature sophisticated warning systems and power management that make it extremely difficult to be caught off guard. Additionally, with the UK's rapidly expanding charging infrastructure—66,779 charging points across 34,570 locations as of July 2024—finding a charge is increasingly straightforward.
What Actually Happens When Your EV Runs Low? The Warning Systems
Unlike petrol cars that suddenly stop, electric cars communicate extensively about energy levels through multiple warning systems.
Progressive Warning Stages
At 20% Battery: Initial low battery warning appears. You still have 40-60 miles of range typically. Navigation automatically shows nearby charging stations.
At 10% Battery: Warnings become more persistent. Some vehicles limit power-consuming features like climate control to preserve range.
At 5% Battery: Most EVs enter "limp mode" or "turtle mode"—reduced performance that extends remaining range by several miles. Many display a turtle icon.
At 0% Battery: When reaching the minimum safe level (not truly 0%—the battery management system reserves some charge), the vehicle gradually slows and stops. Hazard lights remain functional, and most cars retain enough reserve to move a short distance to safety.
How the Car Protects Itself
The battery management system (BMS) progressively reduces power to non-essential systems while prioritising the drivetrain. It prevents complete depletion that could cause permanent damage. Even at 0% displayed, typically 5-10% capacity remains—you just can't access it for driving.
This is one reason why electric cars are more reliable than many expect.
Immediate Steps If You Run Out
Despite warning systems, occasionally drivers do find themselves with depleted batteries. Here's what to do:
Pull Over Safely
As your EV enters final power reduction, you'll have warning before complete stop. Use this time to find the safest location:
On motorways, reach the hard shoulder or emergency refuge area
On regular roads, find a safe lay-by or car park
Turn on hazard lights immediately
Avoid blocking traffic
Contact Breakdown Service
Call your breakdown service immediately (often included in electric car salary sacrifice schemes). Mention:
You have an electric vehicle
Your exact location
Vehicle make and model
You've run out of charge
What to Expect: Mobile Charging vs. Towing
Mobile Charging: Some breakdown services now offer portable batteries providing 10-15 miles of range within 15-30 minutes—enough to reach a proper charging point. However, availability varies by location.
Towing Considerations: EVs typically require flatbed transport rather than traditional towing, as turning wheels while towing can generate electricity and damage the motor. The service will usually take you to the nearest charging station.
The Reality: How Common Is This?
Fewer than 5% of electric car drivers have ever run completely out of charge—compared to approximately 15% of petrol/diesel drivers running out of fuel.
Why EV Drivers Are More Vigilant
Constant Charge Awareness: EVs display battery level prominently with clear percentage displays and range indicators
Home Charging Routine: Most owners charge overnight at home, starting each day with a "full tank"
Predictive Navigation: Modern EVs automatically include charging stops when destinations exceed range
Growing Network: The UK's charging infrastructure expanded 46% year-on-year, making charging increasingly accessible
Electric vehicles actually have advantages over conventional cars:
More advance warning systems
Gradual power reduction rather than sudden cutoff
Battery protection preventing damage
Increasingly available roadside charging

Prevention Strategies
Establish a Home Charging Routine
The most effective prevention is consistent home charging. Most EV drivers charge overnight, similar to smartphones, starting each day with a full battery providing 200+ miles of range.
Home charging is particularly convenient through salary sacrifice schemes, as many packages include home charger installation. The Electric Car Scheme allows adding a charger to your agreement, saving 20-50% on installation through pre-tax deductions.
Without off-street parking? Many areas offer on-street residential charging, and workplace charging is increasingly common. Explore our guide on how to charge without a driveway.
Utilise Modern Technology
Built-in navigation systems calculate whether you can reach destinations on current charge, suggest charging stops if needed, and account for elevation and weather conditions.
Helpful apps include:
Zap-Map: UK's most comprehensive charging database
A Better Route Planner (ABRP): Excellent for journey planning
PlugShare: Community-based with real-time reviews
For detailed reviews, see our guide to best EV charging apps.
The Charge Scheme allows salary sacrifice on charging costs, saving 20-50% on all EV charging at home, work, or in public.
Understand Real-World Range
Official WLTP range varies based on:
Driving Conditions: Motorway driving consumes more than city; cold weather reduces range 20-30%; hot weather with AC reduces 10-15%
Driving Style: Aggressive acceleration and high speeds significantly impact range; smooth driving maximises efficiency
Learn techniques in our guide on optimising your electric car's range.
Plan Long Journeys Strategically
Check charging options along your route beforehand
Plan stops at natural break points
Build in buffer time for charging
Consider seasonal factors—winter requires more frequent charging
Have backup charging locations identified
Weather Considerations
Winter particularly impacts range. Our comprehensive guide on electric cars in winter covers strategies including preheating while plugged in and using seat heaters instead of cabin heating.
Cost Implications
Recovery Service Costs
With Breakdown Cover: Usually covered under comprehensive policies (AA, RAC, Green Flag), though check EV-specific provisions. Many salary sacrifice packages include breakdown cover.
Without Breakdown Cover:
Standard callout: £80-150
Flatbed recovery: £150-300
Mobile charging: £50-100
Charging Costs After Recovery
Rapid Charging (50kW+): 55-85p per kWh, £20-30 for 60kWh battery (20-80%), 30-45 minutes
Fast Charging (7-22kW): 25-45p per kWh, £9-16 for 60kWh battery, 2-4 hours
Home charging costs 15-20p per kWh on standard tariffs, or 7.5p per kWh on EV tariffs. See our guide on home charging costs.
Salary Sacrifice Scheme Benefits
Home Charger Installation Included
Many schemes, including The Electric Car Scheme, allow adding a home charger to your agreement. Installation cost is incorporated into monthly salary deductions from pre-tax salary, saving 20-50% compared to paying after-tax.
Having a home charger fundamentally changes EV ownership. Simply plug in when home, wake up with a full battery. A typical 7kW charger fully charges most EVs overnight (6-10 hours), providing 200+ miles—more than the average UK driver's 20-mile daily commute.
Workplace Charging Access
Many employers offering salary sacrifice also install workplace charging, providing additional charging options beyond home. Particularly valuable for employees in flats without dedicated parking or those wanting to charge during work hours.
The government's Workplace Charging Scheme provides grants up to £350 per socket.
The Charge Scheme: Salary Sacrifice for Charging
The Electric Car Scheme's innovation allows salary sacrificing both vehicle and charging costs:
Receive an app and charging card
Card works across multiple public networks
Charging costs deducted from pre-tax salary
Save 20-50% on all EV charging
This applies at home, work, or public stations, with the same 3% Benefit-in-Kind rate (2025/26) as the vehicle itself.
Reduced Risk Through Planned Charging
Salary sacrifice schemes create structured EV ownership that naturally reduces running-out risk through regular service, comprehensive insurance/breakdown cover, education and support, and financial predictability encouraging proper charging habits.

Technology That Helps
Intelligent Range Prediction
EVs use complex algorithms considering current driving style, climate control usage, road conditions, weather, elevation changes, and traffic to provide accurate range predictions that update continuously.
Navigation System Integration
When entering destinations beyond current range, navigation automatically includes charging stops, selects optimal stations, calculates charging duration, and updates routes in real-time. Most systems are conservative, building in safety buffers.
Preconditioning Features
Many EVs allow preconditioning the battery and cabin while charging—optimising battery temperature and cabin comfort without using battery power, saving several miles of range particularly in winter.
Smartphone Apps
Nearly all modern EVs include apps providing remote battery monitoring, climate control, charging station location, and journey planning.
Over-the-Air Updates
Many modern EVs receive software updates improving battery management, range prediction, charging efficiency, and energy consumption—meaning your car gets better at managing energy over time.
Frequently Asked Questions
Can You Push an Electric Car?
Technically yes, but not recommended and significantly harder than petrol cars. EVs are 200-300kg heavier, electronic parking brakes require power to disengage, and automatic "park" mode engages when switched off. Multiple people are needed for very short distances only. Always call breakdown assistance instead.
Will Running Out of Charge Damage the Battery?
No, not usually. Modern battery management systems prevent true complete discharge. Even at 0% displayed, 5-10% charge remains reserved for protection. However, leaving depleted for weeks can be harmful—arrange recovery and recharging promptly. Learn more about EV battery health.
How Long Does Mobile Charging Take?
Mobile units typically provide 10-15 miles of range in 15-30 minutes—enough to reach proper charging stations. They're designed for emergency range, not full charges. Availability varies, with urban areas having better coverage.
What If I'm on a Motorway?
Move to the left lane immediately, reach the next emergency refuge area or hard shoulder, turn on hazards, exit away from traffic, and call 999 if in immediate danger. Motorway recovery is prioritised. Most service stations now have rapid charging, typically spaced every 20-30 miles.
Does This Affect My Salary Sacrifice Agreement?
No. Running out of charge doesn't affect monthly deductions, agreement terms, or future eligibility. It's treated as driver responsibility. Breakdown cover in your package should cover recovery. Only if it leads to uncovered accident damage might there be implications.
Conclusion
Running out of charge is significantly rarer than running out of petrol—fewer than 5% of EV drivers have ever experienced completely depleted batteries versus 15% of petrol drivers. Modern EVs provide progressive warnings, enter reduced performance mode to extend range, and stop safely without battery damage.
Prevention is straightforward: establish home charging routines, use navigation systems, leverage the UK's 66,779+ charging points, and plan accordingly for longer journeys.
Through schemes like The Electric Car Scheme, drivers benefit from included home charger installation (saving 20-50% through pre-tax deductions), comprehensive breakdown cover, The Charge Scheme for salary sacrifice on all charging, and bundled monthly payments with the current 3% Benefit-in-Kind rate (2025/26).
Range anxiety remains a commonly cited barrier to EV adoption, yet evidence shows this fear is unfounded. With average range of 212 miles and rising, expanding infrastructure, sophisticated technology, and simple charging routines, running out is increasingly unlikely.
For UK drivers averaging just 20 miles daily, even modest electric cars provide adequate range. With home charging costing 7.5-20p per kWh versus petrol equivalent of 60p+ per kWh, the financial incentive to keep charged is compelling.
