Electric Car Breakdown: What Happens When Your EV Fails?

# Electric Car Breakdown: What Happens When Your EV Fails?

As electric vehicles become increasingly common on UK roads, drivers are discovering that EV breakdowns present unique challenges compared to traditional petrol or diesel cars. From high-voltage systems to specialised recovery requirements, understanding what can go wrong—and how to get help—is essential for every electric car owner.

Common Electric Car Breakdown Causes

Battery-Related Issues

• **Complete Battery Depletion:**
• Most common EV breakdown cause (similar to running out of fuel)
• Often occurs due to range miscalculation or charging point failures
• Cannot be easily resolved roadside without mobile charging

• **12V Auxiliary Battery Failure:**
• EVs still use 12V batteries for lights, electronics, and computers
• Failure prevents car from starting, even with full main battery
• More common than main battery issues

• **Charging System Problems:**
• Faulty charging port or connector damage
• Internal charging system failures
• Software glitches preventing charging

Mechanical and Electronic Issues

• **Tyre Problems:**
• Punctures and wear issues identical to conventional cars
• EV tyres may wear differently due to instant torque
• Many EVs use special low-rolling-resistance tyres

• **Motor and Drive System Faults:**
• Electric motor failures (rare but complex to repair)
• Inverter or controller problems
• Regenerative braking system issues

• **Software and Computer Problems:**
• Update failures rendering vehicle inoperable
• Sensor malfunctions affecting critical systems
• Touchscreen or interface freezes

What Makes EV Breakdowns Different

High Voltage Safety Concerns

• **Recovery Complications:**
• High-voltage systems (400-800 volts) require specialist knowledge
• Not all breakdown operators trained for EV recovery
• Special isolation procedures needed before vehicle movement

• **Repair Restrictions:**
• Many roadside repairs impossible due to safety requirements
• Specialist EV-qualified technicians often needed
• Diagnostic equipment must be EV-compatible

Limited Roadside Solutions

• **What Can Be Fixed Roadside:**
• 12V battery replacement or jump-start
• Tyre changes (using standard equipment)
• Basic fuse replacement
• Software resets in some cases

• **What Cannot Be Fixed Roadside:**
• Main battery charging (without mobile charging units)
• High-voltage system repairs
• Complex electronic control unit problems
• Motor or inverter repairs

Emergency Mobile Charging

How Mobile EV Charging Works

• **Service Availability:**
• Growing number of mobile charging services across UK
• Emergency charging vans with portable battery packs
• Typical charge: 10-30 miles range in 15-30 minutes

• **Limitations:**
• Not yet universally available
• More expensive than standard charging
• Limited charge capacity per visit

• **Major Providers:**
• AA and RAC now offer limited mobile charging
• Specialist EV breakdown services emerging
• Some local mechanics investing in portable charging equipment

Emergency Charging Costs

• **Typical Pricing:**
• Callout fee: £50-100
• Charging cost: £1-3 per mile of range added
• Total emergency charge: £80-200 typical

• **Compared to Conventional Breakdown:**
• Similar cost to traditional breakdown recovery
• Often cheaper than vehicle recovery to charging point

EV-Specific Recovery Procedures

Safety Requirements

• **Before Recovery:**
• Vehicle must be properly isolated
• High-voltage systems checked and secured
• Special lifting points identified
• Battery condition assessed

• **Recovery Vehicle Requirements:**
• Flatbed preferred over traditional towing
• Operator must be EV-trained
• Appropriate lifting and securing equipment
• Understanding of weight distribution

Destination Considerations

• **Where EVs Get Recovered:**
• EV-specialist garages (limited number)
• Manufacturer-approved service centres
• Charging points with workshop facilities
• Home address (if charging available)

• **Recovery Distance Impact:**
• May need longer-distance recovery to reach EV specialist
• Traditional local garages may not accept EV work
• Higher recovery costs due to specialist requirements

Getting Help for EV Breakdowns

Traditional Breakdown Services

• **AA EV Services:**
• Mobile charging available in some areas
• EV-trained patrol officers increasing
• Specialist recovery vehicles in major cities
• Limited rural EV expertise

• **RAC EV Support:**
• Emergency charging service
• EV-qualified technicians
• Partnerships with charging networks
• Growing but not comprehensive coverage

• **Limitations:**
• Rural coverage still patchy
• Not all engineers EV-qualified
• Limited mobile charging availability
• Recovery to EV specialists may incur extra costs

Specialist EV Breakdown Services

• **Dedicated EV Providers:**
• 100% EV-focused breakdown services
• All technicians EV-qualified
• Mobile charging standard
• Understanding of EV-specific issues

• **Availability:**
• Currently limited to major urban areas
• Growing rapidly across UK
• Often more expensive than traditional services
• Better equipped for complex EV problems

Modern Mobile Mechanic Services

• Apps like Hault are adapting to EV needs by:
• Partnering with EV-qualified mobile mechanics
• Ensuring technicians carry appropriate safety equipment
• Providing access to EV diagnostic tools
• Offering transparent pricing for EV services

Insurance and Warranty Considerations

EV Insurance Differences

• **Breakdown Cover:**
• Some policies specifically exclude high-voltage work
• EV-specialist cover often more comprehensive
• Mobile charging may or may not be covered
• Check policy terms for EV-specific provisions

• **Recovery Limitations:**
• Standard policies may not cover EV specialist recovery costs
• Extended distances to appropriate facilities
• Hire car arrangements for longer repair times

Manufacturer Warranty Support

• **What's Usually Covered:**
• Roadside assistance during warranty period
• Recovery to authorised service centres
• Sometimes mobile charging included
• Courtesy vehicle provision

• **Geographic Limitations:**
• May require recovery to distant service centres
• Rural area coverage often limited
• European cover varies by manufacturer

Prevention and Preparation

Range Management

• **Best Practices:**
• Plan routes with charging stops
• Never rely on single charging point
• Keep 20-30% buffer charge minimum
• Use multiple route planning apps

• **Emergency Preparation:**
• Know locations of rapid chargers on regular routes
• Download multiple charging network apps
• Carry charging cables appropriate for destination
• Understand your car's emergency charging options

Regular Maintenance

• **EV-Specific Checks:**
• 12V auxiliary battery condition
• Charging port cleanliness and condition
• Software updates (may prevent roadside issues)
• Tyre condition (affects range significantly)

• **Professional Servicing:**
• Use EV-qualified service centres
• Regular high-voltage system safety checks
• Coolant system maintenance (battery thermal management)
• Brake system service (regenerative braking affects conventional brakes)
