As electric vehicles (EVs) continue to gain popularity worldwide, understanding their unique servicing requirements becomes essential for car owners. Electric car servicing focuses on maintaining EVs' functionality, efficiency, and safety. Unlike traditional internal combustion engine (ICE) vehicles, EVs have fewer moving parts but rely heavily on complex systems like battery packs, electric motors, and advanced software. Proper servicing ensures these components' longevity and the car's overall health.
What Is EV Car Servicing?
Electric car servicing involves inspecting, maintaining, and repairing components unique to EVs while addressing general vehicle upkeep. Since EVs lack traditional engines, parts such as oil filters, spark plugs, and timing belts are unnecessary. However, EVs introduce new components and systems that require regular checks and maintenance:
Battery Maintenance
The battery pack is the heart of an electric car, supplying the energy needed to power the vehicle. Servicing includes checking the battery's health, ensuring proper connections, and monitoring for signs of degradation. Technicians may also update the battery management system (BMS) software, which optimises charging and usage patterns.
Electric Motor and Powertrain
Electric motors are more straightforward than ICE engines but still require regular inspection. This includes checking for wear and tear, ensuring proper lubrication of moving parts, and verifying the functioning of the inverter, which converts direct current (DC) from the battery to alternating current (AC) for the motor.
Software Updates
EVs rely on software to manage power distribution and control autonomous driving features. Routine servicing includes software diagnostics and updates to enhance performance, improve efficiency, and patch security vulnerabilities.
Regenerative Braking System
EVs use regenerative braking, which converts kinetic energy back into electricity to recharge the battery. Servicing ensures this system works efficiently and checks the physical brakes, which may wear unevenly due to less frequent use.
Tyres
Because EVs are heavier due to their battery packs and offer instant torque, tyres can wear out faster. Servicing includes tyre rotation, alignment, and ensuring appropriate pressure to maintain safety and efficiency.
Cooling and Heating Systems
Thermal management is vital in EVs to prevent battery and electric motor overheating. Servicing ensures that coolant levels are adequate and that heating systems function correctly.
Why Is EV Car Servicing Important?
Regular servicing of an electric car ensures not only the longevity of the vehicle but also its safety, efficiency, and optimal performance. Here are the key reasons why electric car servicing is crucial:
Maximising Battery Lifespan
The battery is the most expensive component of an EV, often accounting for 30-40% of the vehicle's total cost. A well-maintained battery retains its capacity and charging efficiency over time, reducing the risk of premature replacement. Servicing ensures the battery operates within its optimal range, avoiding deep discharges or overheating, which can degrade it.
Ensuring Safety
Electrical systems in EVs operate at high voltages, posing potential safety risks if not maintained. Regular checks can identify issues such as frayed wiring, loose connections, or coolant leaks that could lead to electrical fires or other hazards. Furthermore, software updates often include safety improvements.
Preserving Efficiency
EVs are known for their energy efficiency compared to ICE vehicles. However, poorly maintained components, such as underinflated tyres or an inefficient cooling system, can reduce range and overall performance. Servicing helps maintain peak efficiency, ensuring drivers get the most out of every charge.
Retaining Warranty and Resale Value
Many EV manufacturers require adherence to a servicing schedule to maintain warranty coverage. Skipping service appointments could void the warranty, leaving the owner responsible for costly repairs. Moreover, a well-documented service history enhances the resale value of an EV, reassuring potential buyers of its condition.
Enhancing Longevity
Just as regular servicing extends the life of traditional cars, it ensures that EVs remain operational for years to come. This includes protecting the battery's longevity and other critical systems like the inverter, motor, and regenerative braking mechanism.
Identifying Issues Early
Servicing allows technicians to spot potential problems before they escalate. For example, a minor software glitch might not affect performance immediately but could lead to significant issues if left unresolved. Early detection minimises downtime and repair costs.
How Often Should EV Cars Be Serviced?
The frequency of servicing depends on the manufacturer's guidelines and the specific model of the EV. Some components, like tyres and brakes, may require inspection more frequently, while other checks can be done annually. Typically:
​
-
Battery checks are recommended every year or 20,000 miles.
-
Software updates may occur remotely or during a service visit, depending on the manufacturer.
-
Brake system inspections might be needed every 12,000 to 15,000 miles, especially for regenerative braking systems.
-
Tire maintenance is often required every 6,000 to 8,000 miles, depending on driving conditions.
Owners should always refer to their vehicle's manual for the recommended servicing schedule.
Common Myths About EV Car Servicing
As EVs become more widespread, several misconceptions about their maintenance have arisen. Here are some myths and realities:
​
Myth 1: EVs Don't Require Servicing
Reality: While EVs generally have lower maintenance requirements than ICE vehicles, they still need regular checks to ensure safety, efficiency, and longevity.
Myth 2: Servicing EVs is More Expensive
Reality: EVs lack many parts that require frequent replacement in ICE vehicles, such as oil and air filters. While specific repairs, like battery replacements, can be costly, routine servicing is often cheaper.
Myth 3: Any Mechanic Can Service an EV
Reality: EVs require specialised knowledge and tools. They must be serviced by trained technicians familiar with high-voltage systems and EV-specific technologies.

Electric car servicing is vital for maintaining the vehicle's health, safety, and performance. It ensures the longevity of critical components, enhances efficiency, and provides peace of mind for owners. With the growing adoption of EVs, understanding and adhering to proper servicing practices will not only extend the life of these vehicles but also contribute to the sustainability of transportation. As technology advances, EV servicing will become even more streamlined, making it easier for owners to keep their cars in optimal condition.
