Electric car maintenance: a practical guide on how to perform it simply and effectively

Electric mobility is no longer a mirage: more and more drivers are choosing to switch to electric cars to reduce management costs and contribute to a more sustainable future. However, one doubt remains recurring: how does the maintenance of an electric car work? Is it really simpler than that of a traditional vehicle? And how much does it cost to keep it efficient over time?

The short answer is yes: maintenance of an electric car is on average lighter, less expensive, and more predictable. But to fully understand the benefits, it is useful to analyze in detail the differences, routine and extraordinary interventions, battery management, and practical tips that help extend the life of the vehicle.

Main differences with internal combustion cars

Absence of engine oil, fuel filters, and spark plugs

The first evident advantage concerns the simplification of the engine: there is no longer a need for oil changes, fuel filters, or spark plugs, all typical operations of internal combustion engines. This not only reduces costs but also the frequency of interventions in the workshop.

Regenerative braking and lower brake wear

Thanks to regenerative braking, part of the energy produced during deceleration is recovered and reinjected into the battery. In addition to improving efficiency, this mechanism limits the wear of the brake pads, which last longer compared to those of combustion cars.

Reduced mechanical components and fewer parts subject to failure

An electric motor consists of many fewer moving parts compared to a traditional one. This means less friction, less maintenance, and lower risks of mechanical failures. Obviously, tires, suspensions, and the air conditioning system, common to any type of vehicle, remain to be cared for.

Routine maintenance of an electric car

Tire check and tire rotation

The greater weight of electric cars and the instant torque of the electric motor put a strain on the tires. It is good practice to check the pressure once a month and arrange for rotation every 10-15,000 km to ensure even wear.

Brake, suspension, and steering checks

Even though the brakes wear out more slowly, it is important to subject them to regular checks. The same goes for suspensions and steering, elements that directly affect safety and driving comfort.

Cleaning and maintenance of the air conditioning system

The cabin filter should be replaced periodically to ensure clean air and optimal air conditioning operation. Careful maintenance of the system avoids bad odors and keeps energy efficiency high.

Software updates and periodic electronic diagnostics

Electric cars are real digital systems. Updating the software allows for new features, bug fixes, and performance improvements. Periodic electronic checks, often executable remotely, ensure that everything runs smoothly.

The battery: the heart of EV maintenance

Average battery life and factors affecting efficiency

The battery represents the most delicate and expensive component of the electric car. On average, it lasts 8-10 years, but it can exceed these thresholds if treated properly. Extreme temperatures, aggressive driving styles, and careless charging habits can reduce its longevity.

State of health check with periodic inspections (SoH)

The “State of Health” of the battery indicates its efficiency compared to new. Authorized workshops can analyze parameters such as remaining capacity and internal resistance to provide an accurate picture of the battery pack's conditions.

Diagnostics using professional tools and detailed reports

Specialized analyses generate clear and reliable reports, useful for scheduling any interventions or simply for monitoring the battery's performance over time.

Key parameters to monitor to ensure autonomy and safety

Values to keep an eye on include charge cycles, depth of discharge, and operating temperatures. Keeping them within recommended limits ensures consistent and safe performance.

Good daily charging practices

An intelligent use of charging makes a difference. Avoid completely discharging the battery, do not keep it always at 100%, and prefer slow charging when possible are good habits to preserve its long-term health.

Extraordinary maintenance: what to expect

Possible electronic failures and control unit issues

Although rare, electronic failures can occur. The management control unit or some sensors may require replacements. Fortunately, these are much less frequent interventions compared to failures of a traditional engine.

Check and maintenance of the home charging system (wallbox)

The home charging system should be treated as an integral part of the vehicle. Cables, plugs, and wallboxes must be periodically checked to ensure safety and consistent performance.

Battery replacement or regeneration in exceptional cases

Battery replacement is a rare operation and covered by extended warranties. Alternatively, more and more operators offer regeneration, which allows restoring part of the capacity at a lower cost than a complete replacement.

Costs of electric car maintenance

Typical expenses for annual routine maintenance

An annual check of an electric car can cost between 100 and 200 euros. The absence of interventions related to the thermal engine allows for tangible savings compared to gasoline and diesel.

Extraordinary interventions and long-term cost estimates

Extraordinary interventions are infrequent. The most expensive remains battery replacement, but multi-year warranties and technological improvements are progressively reducing the economic impact of this scenario.

Cost comparison between electric vehicles and gasoline or diesel cars

The difference in maintenance costs is evident. Where a traditional car requires between 500 and 700 euros annually, an electric one maintains an average of 200-300 euros.

Recommended intervention frequency

Maintenance intervals based on kilometers and years

The general rule is a check every 15-30,000 km or once a year. However, some checks such as electronic or software ones can be done even more often and remotely.

Difference between annual check-up and predictive maintenance

Predictive maintenance, supported by smart sensors, allows anticipating potential issues. It is a growing technology that reduces unexpected downtimes and extraordinary expenses.

Practical tips for extending the life of the electric car

How to preserve battery autonomy over time

Keep the charge between 20% and 80%, avoid extreme temperatures, and use slow charging when possible are simple but effective precautions.

Driving styles that reduce energy consumption and wear

A smooth driving style, with gentle accelerations and braking, not only increases autonomy but also extends the life of mechanical components.

Parking and environmental conditions that affect battery life

Excessive heat is the number one enemy of batteries. Parking in the shade or in a garage reduces the risk of overheating.

Importance of original accessories and certified cables

Using certified cables and components is essential. Non-original products can compromise safety and reduce charging efficiency.

The importance of specialized assistance

Authorized workshops and certified EV assistance centers

Turning to qualified technicians means relying on professionals trained in the specifics of electric cars. It is a guarantee of quality and safety.

Why to avoid DIY maintenance of the battery

The battery operates at high voltage: intervening without specific skills is risky. It is better to rely on experienced hands for any issue.

Evolution of EV maintenance in the coming years

Predictive maintenance thanks to artificial intelligence and IoT sensors

The use of artificial intelligence and connected sensors will allow for precise predictions of failures and optimization of maintenance cycles.

Remote diagnostics and over-the-air software updates

More and more manufacturers are offering remote updates, which improve performance without needing to go to the workshop.

How new technologies will further reduce management costs

With more resilient batteries and increasingly advanced software, management costs will tend to decline further, making electric vehicles even more convenient.
