EV Maintenance Costs: How Much Do You Really Save?
It's well known that electric vehicles (EVs) are more cost-effective to operate than gas-powered cars, thanks to significantly lower electricity costs compared to petrol or diesel. However, when considering technical maintenance, do modern EVs with cutting-edge technology remain the more budget-friendly option? In this article, we take a detailed look at all possible maintenance costs to determine whether EVs remain the more cost-effective choice.

EV Care: More Than Just Plugging In
Traditional ICE and hybrid cars require maintenance every 5,000–10,000 miles, including oil and filter changes. In contrast, EVs have a different structure that extends maintenance intervals. But does that mean they require no servicing at all? Let’s break down the essential maintenance tasks for EV owners:
Battery Health Managing
The battery is the heart of every electric vehicle, making regular health checks essential. We recommend inspecting battery performance annually or every 15,000 miles to detect early signs of degradation and ensure all connected systems function properly. Monitoring battery health helps maintain optimal range, efficiency, and long-term reliability, preventing costly repairs down the line.
Cooling System Inspection
Electric vehicles require periodic cooling system inspections, usually at 150,000-mile or five-year intervals (varies by model). If the coolant has degraded or levels are low, replacing it is essential to maintain battery efficiency and prevent overheating. This is especially important for high-performance EVs like the Tesla Model S Plaid, which generate more heat due to their powerful motors. For such vehicles, more frequent cooling system checks are highly recommended to optimize longevity and performance.
Brake System Maintenance
While EVs require routine brake maintenance, such as replacing brake pads, fluid, and discs, their braking systems typically have much longer service intervals compared to gasoline vehicles. This is primarily due to regenerative braking, which reduces wear and tear by allowing the vehicle to slow down without engaging traditional brakes — especially with the one-pedal driving feature. Learn more about this technology in our in-depth article on regenerative braking.
Oil Changing
Surprisingly, electric cars also require oil changes — but not for an engine. EVs use differentials to transfer power fr om electric motors to the wheels, and the differential oil needs replacement approximately every 80,000–100,000 miles. While this interval is far longer than in internal combustion engine (ICE) vehicles, neglecting it could lead to excessive wear or even damage, especially for drivers who accelerate aggressively. Regular maintenance ensures smooth performance and extends the lifespan of your EV’s drivetrain.
Other Essential Maintenance
Just like any other vehicle, electric cars require regular attention to components such as cabin filters, wiper fluid, wiper blades, and the 12V battery, which most EVs still have alongside the main battery. However, there's one significant difference: EVs typically need tire replacements more often. This is due to the heavier weight of electric vehicles, which places more strain on the tires, causing them to wear out faster compared to gas-powered cars. Tires are the only component that tends to need more frequent replacement in EVs compared to conventional vehicles.
Why EVs Have Lower Maintenance Costs?
Now that we’ve covered all the essential maintenance aspects of EVs, it’s clear that electric vehicles offer a more convenient and budget-friendly ownership experience compared to internal combustion engine (ICE) cars. But what exactly makes EV maintenance and running costs lower? Let’s break down the key factors that contribute to these savings.
- Fewer Moving Parts: At first glance, EVs may seem complex, but their construction is actually simpler than that of gas-powered cars. This simplicity means fewer components are prone to wear and failure.
- Extended Maintenance Intervals: Unlike gas-powered cars, EVs don’t require frequent maintenance routines like oil changes or complex engine servicing. Their maintenance intervals are significantly longer, often involving just a cabin filter replacement and routine battery and motor checks.
- Durability of EV Components: Designed for longevity, EV batteries and motors can run for over a decade with minimal repairs. Their reliability makes EV maintenance far more cost-effective than that of gas-powered vehicles.
Cost Comparison of EV, ICE, and Hybrid Car: Real Example
To evaluate cost-effectiveness, we’ve selected three different types of vehicles for comparison. The Tesla Model 3 Long Range AWD represents electric vehicles, the BMW 330i stands for traditional internal combustion engine (ICE) cars, and the Toyota RAV4 Hybrid exemplifies hybrid technology. Let’s find out which one is the most economical choice!
1. Standard Maintenance Price
- Tesla ≈ $150
- BMW ≈ $300
- Toyota ≈ $380
2. Total Maintenance Price (10 Years Period)
- Tesla ≈ $4,000
- BMW ≈ $9,500
- Toyota ≈ $5,500
3. Fuel Expenses (10 Years Period)
- Tesla ≈ $3,000
- BMW ≈ $10,000
- Toyota ≈ $7,000
As demonstrated, the Tesla offers significantly greater affordability compared to both petrol and hybrid vehicles. With an EV, you not only reduce maintenance costs but also benefit from substantial fuel savings.

Tips to Minimize EV Maintenance Costs
Owning an EV undoubtedly offers substantial cost savings compared to conventional cars. Yet, certain challenges may emerge that could unexpectedly and sharply increase ownership costs. Here, we provide expert advice on how to prevent these issues and ensure a seamless EV experience.
- Avoid Charging to 100%: Frequent full charging can accelerate battery degradation, potentially resulting in costly replacements — sometimes reaching up to $15,000. To maximize battery lifespan and maintain optimal performance, set a charging lim it of 80-90% for daily use, reserving full charges only for longer trips. This simple adjustment can significantly enhance your EV’s longevity while reducing long-term maintenance costs.
- Avoid Full Discharging: Just like frequent full charging, allowing your EV battery to fully discharge can significantly harm its lifespan. Additionally, a completely drained battery may prevent you from unlocking or starting your car. To avoid issues, maintain the charge above 10-20% and keep the car plugged in when leaving it unused for long periods.
- Limit Fast Charging: Frequent use of DC fast chargers can accelerate battery degradation, just like regularly charging to 100%. Instead, opt for AC home charging for daily use — it’s safer for the battery and conveniently charges your EV overnight. Reserve fast charging for long trips or urgent situations.
- Avoid Extreme Temperatures: Extreme cold or heat can negatively impact battery health and efficiency, leading to increased energy consumption as thermal management systems work harder. To preserve battery life, park your EV in a garage or covered parking whenever possible, especially in harsh weather conditions. For expert tips on cold-weather care, explore our EV winterproofing guide.
- Make Regular EV Check-Ups: While EVs require less maintenance than traditional cars, it’s crucial to inspect key components regularly. Checking the battery, electric motors, suspension, and tires helps prevent unexpected issues. We recommend a full diagnostic every 1–2 years to keep your EV in top shape.
