Electric Car Maintenance Costs Vs Traditional Cars

Electric Car Maintenance

Electric cars have their pros and cons, but they are often more affordable to maintain compared to standard cars. One potential cost, which is the most expensive, involves replacing the battery, which could amount to $10,000.

However, the majority of the time, electric vehicle maintenance tends to be inexpensive. This is due to their reduced number of moving parts (for example, they have a simplified transmission and don’t have alternators), resulting in fewer opportunities for damage compared to petrol cars.

EVs are known for their cost advantages regarding maintenance, with savings of around 30% compared to traditional cars, and potentially even up to 50%. However, it should be noted that maintenance costs can vary based on the specific make and model.

When comparing plug-in hybrids to full-petrol or diesel cars, they generally come out as the more affordable option in terms of maintenance.

However, it’s important to mention that they still have some conventional car parts, including an engine, exhausts, clutches, and gearboxes, which may require maintenance and incur associated costs. On the other hand, fully-electric cars tend to be less expensive to maintain.

EV Battery Repair Costs

Battery cells can be repaired instead of replacing the entire battery, though it is quite uncommon and most people won’t encounter this issue.

Costs for repairs differ depending on the manufacturer, and repairs need to be done directly by them. It’s advisable to verify if the warranty covers battery repairs.

An EV battery repair is going to extend the battery life, allowing you to postpone a more expensive battery replacement.

Required maintenance for an electric car

Here’s the maintenance needed to keep your electric car in good shape and prolong its lifespan:

1. EV Battery Pack Maintenance

Regular check-ups and maintenance are essential to ensure the health and performance of your EV’s battery pack. This includes monitoring its capacity, balancing the cells, and keeping it within the recommended temperature range for optimal longevity.

The National Renewable Energy Laboratory of the United States is predicting that today’s electric vehicle (EV) batteries will have service lives ranging from 12 to 15 years when used in moderate climates.

However, if regular use takes place in extreme environments, this estimated service life decreases to 8 to 12 years.

Despite these variations, EV batteries generally require minimal maintenance throughout their service life. Nevertheless, there are several actions that drivers can take to prolong the life of their EV’s battery pack:

A. Avoid extreme temperatures

If you want to maximize the lifespan of your EV’s battery, it’s crucial to keep it away from extreme temperature conditions. Trust me, extreme heat, and cold can eventually harm those cells! So, try to find a cozy spot to park your electric beauty, away from scorching sun or freezing winters. Your battery will thank you for it!

Anyway, automakers take extreme temperatures, both hot and cold, into account when developing their electric vehicles (EVs). They equip these vehicles with auxiliary cooling and heating systems to ensure the battery temperature remains at acceptable levels.

This practice generally prevents adverse effects on the battery caused by temperature fluctuations.

B. Limit the use of fast chargers

Fast chargers, despite their convenience in rapid recharging, degrade battery packs at a quicker rate than slower 120- or 240-volt charging. However, the exact impact of fast charging on battery life remains uncertain in these early stages of modern EVs.

In a road-trip scenario, fast charging becomes necessary because EVs can’t charge themselves, so there is no reason to avoid it.

Nonetheless, relying exclusively on fast charging when buying an EV is not advisable, both in terms of battery life and cost. It is worth noting that fast charging costs three to four times more per kilowatt-hour of energy compared to home charging.

C. Use the battery between 20-80% charge

Batteries degrade faster when charged to their maximum capacity and especially when completely discharged. Fortunately, many manufacturers help fight battery degradation by limiting full-capacity charging.

Most cars offer settings to charge to less than 100 percent, with automakers often recommending a daily charge level of 85 or 90 percent.

2. Electronics

Regular check-ups and firmware updates for the power electronics system are crucial for optimal efficiency and performance. This includes monitoring inverters, converters, and other electronic components.

Given that EVs rely heavily on electronics, owners should also consider car cybersecurity. VPN will help with this, the main thing is high-speed and safe. For example, VeePN offers VPN connection speeds up to 100 Mbps on most of their servers. This is enough for any media content, including high definition.

3. Brakes

Despite regenerative braking, EVs still use mechanical brakes. It’s important to inspect brake pads and rotors regularly to ensure they are in good condition and replace them when necessary to maintain safe and efficient braking performance.

4. Tires

Regular tire maintenance is crucial for both safety and efficiency. This involves rotating tires, checking inflation levels, and monitoring tread depth. Good tire maintenance helps ensure optimal grip and extends tire lifespan.

It’s worth noting that the regenerative braking system employed in electric cars can contribute to a longer tire lifespan. With regenerative braking, the electric motor helps slow down the vehicle, reducing the wear on the brake pads.

This gentler braking behavior can lead to less frequent tire replacements and extended longevity for the tires.

5. Cooling System

EVs rely on cooling systems to regulate battery and motor temperatures. It’s important to inspect, clean, and potentially replace cooling components as needed to prevent overheating and maintain optimal performance and longevity.

6. Charging System

Electric cars generally require less maintenance compared to petrol cars. With fewer parts, there is a reduced chance of things going wrong. Additionally, routine costs such as oil changes are not necessary for EVs.

EV manufacturers typically provide service plans for their electric cars. These plans, similar to mobile phone contracts, are often paid monthly by drivers in exchange for regular servicing.

Compared to servicing petrol cars, these services are generally more affordable. For instance, the Renault Zoe’s service plan costs only $399 for three years and 30,000 miles.

However, it’s important to note that these service plans do not typically cover wear and tear items such as brake components or windscreen wipers.

How Often Should You Contact the Service?

The frequency of car servicing varies according to the specific car model. Nissan recommends a service for its Leaf after every 12,000 km, while Tesla suggests inspections every 16,000 – 20,000 km.

Regular servicing is essential for maintaining optimal car performance, maximizing battery lifespan, and preventing costly maintenance issues in the future.

How Long Does a Battery Last in EVs?

The battery is a crucial component of an electric vehicle, and it may require replacement over time. The lifespan of a battery depends on various factors such as driving habits and the specific EV model.

Generally, a good rule of thumb is to add two years to the EV’s warranty and anticipate the battery to last approximately that long.

For instance, estimations suggest that the Nissan Leaf and Jaguar I-Pace typically endure for around eight years, while the Tesla Model 3 has an anticipated lifespan ranging from 21 to 35 years.

As an EV ages, it undergoes degradation with each charging cycle. Initially, these degradations are minimal, and their impact on the EV’s driving range might go unnoticed. However, over time, these increments accumulate, significantly affecting the battery’s lifespan.

On average, EVs experience an annual range loss of about 1-2%, meaning that after five years of use. You may experience a reduction of approximately 10% of the battery’s total capacity.
