Electric Car Maintenance and Servicing Guide

Electric cars (EVs) are often praised for their efficiency, eco-friendliness, and lower running costs compared to traditional petrol or diesel vehicles.

However, like all vehicles, they require regular maintenance and occasional servicing to keep them in top condition.

This guide provides an in-depth look at electric car maintenance and servicing, covering everything you need to know to keep your EV running smoothly.

What Requires Maintaining and Servicing on Electric Cars?

While EVs have fewer moving parts than internal combustion engine (ICE) vehicles, there are still several key components that require attention:

Electric Motor and Battery

The electric motor and battery are the heart of an EV.

Though these components are designed to last for years, they benefit from periodic checks to ensure optimal performance.

• Battery Health: Most EV batteries are built to last 8-10 years. Regular software updates and avoiding frequent deep discharges can prolong battery life.
• Cooling Systems: Many EV batteries use liquid cooling systems to prevent overheating. These systems may require periodic inspections and coolant replacement.

Oil and Coolant

Although EVs don’t require engine oil changes, some components, such as gearboxes or thermal management systems, use specific oils or coolants that need periodic replacement.

Brake Pads & Brake Fluid

Electric cars use regenerative braking, which reduces wear on brake pads.

However, brake fluid requires regular replacement, typically every 2-3 years, as it can degrade over time.

Tyre Wear and Tyre Pressure Checks

EVs are heavier than ICE vehicles due to their batteries, which can cause increased tyre wear.

Regularly checking EV tyre pressure and tread depth is essential for safety and efficiency.

Suspension

Suspension components, like shock absorbers and springs, wear out over time and should be inspected during routine servicing to ensure a smooth ride.

Windscreen Wiper Replacement

Wipers need replacing periodically to maintain visibility during adverse weather conditions.

Replacing them is an inexpensive yet vital aspect of maintenance.

MOT

In the UK, EVs over three years old must undergo an annual MOT test, which checks roadworthiness, safety, and emissions (though EVs are exempt from emissions testing).

How Often Do Electric Cars Require Servicing?

Most EV manufacturers recommend servicing intervals of 12 months or every 10,000 to 15,000 miles, whichever comes first.

This includes checks on:

• Battery health and performance
• Electrical systems
• Brake pads and fluid
• Tyres and suspension

However, consult your owner’s manual for manufacturer-specific guidance, as requirements can vary.

Electric Car Maintenance and Servicing Costs vs Combustion Engines

EVs generally cost less to maintain than ICE vehicles due to fewer moving parts. Here’s why:

• No Oil Changes: EVs eliminate the need for regular oil changes.
• Brake Longevity: Regenerative braking extends the life of brake pads.
• Simpler Powertrains: With no clutch, timing belt, or exhaust system, there’s less to service or replace.

Studies suggest that EV owners save 20-30% on maintenance costs compared to ICE vehicles over the vehicle’s lifetime.

What Happens When an Electric Car Breaks Down?

If an EV breaks down, it’s often due to flat tyres, 12V battery issues, or software faults rather than mechanical failures.

Most EV manufacturers provide roadside assistance, and specialised EV recovery services are becoming more widespread. Additionally:

• Battery Depletion: If the main battery runs out of charge, towing may be required as roadside charging facilities are still limited in some areas.
• Specialist Repairs: EV-specific components like batteries and electric motors require specialised repairs, often at approved service centres.

Conclusion

Maintaining an electric car is simpler and often more affordable than maintaining a traditional ICE vehicle.

By understanding the unique maintenance requirements of EVs and adhering to regular servicing schedules, you can maximise performance, safety, and longevity while enjoying the many benefits of electric driving.

Always refer to your vehicle’s manual for specific recommendations, and consult a qualified EV technician for any concerns.

With proper care, your electric car will serve you well for many years to come.
