How to Maintain Your EV

Electric vehicles are known for their low maintenance, clean operation, and cost savings compared to gasoline powered vehicles. Yes, it's true that EVs don't require oil changes anymore, but that doesn't mean they don't need to be serviced regularly. Regular maintenance is essential to ensure they remain efficient, reliable, and safe for years to come.

EVFinder recommends getting your EV serviced and inspected every 6 months to ensure optimal performance and longevity. Here's a detailed guide on things to look out for.

Brakes & Regenerative Braking

EVs use regenerative braking, which reduces dependence on traditional brakes and slows brake pad and rotor wear. However, those traditional brakes still need attention. Have them inspected during routine service appointments for wear, corrosion, and proper fluid levels. In colder climates or places where road salt is commonly used, making sure brake calipers are lubricated annually can prevent seizing and corrosion-related issues. Additionally, brake fluid should be replaced as outlined in your owner's manual, which is typically every two to three years, to maintain effectiveness and safety.

Fluids & Filters

Although EVs do not require oil changes, several other fluids and filters are still part of their maintenance routine. Coolant is crucial for temperature regulation in the battery, motor, and power electronics. It needs to be checked and replaced on schedule as per manufacturer guidance. Windshield washer fluid should be topped up regularly to ensure clear vision, and the cabin air filter should be inspected regularly, to keep the interior air clean and comfortable.

Battery Care

The battery pack is arguably the most important and expensive component in your EV, so proper care directly affects your vehicle's health and residual value. It's strongly recommended to maintain your battery's state of charge within the 20% to 80% range during regular use. Charging to 100% should be reserved only for long journeys, as frequent full charges can speed up the process of cell degradation. Using DC fast charging is convenient when on the road or in a pinch, but it does generate extra heat and puts additional stress on the battery. Regularly relying on the slower Level 2 charging stations, or home charging for daily needs, helps preserve the battery's long-term capacity and health.

Additionally, extreme temperatures can negatively impact the health of the battery. High heat can speed up the degradation process while cold temperatures affect performance. Parking in garages or shaded spaces during hot days and keeping your vehicle plugged in during colder months to enable its battery thermal management system, are good habits to perform. As battery management technologies and efficiency often improve through software, enabling over-the-air updates or checking for software upgrades periodically is another practical step to keep the battery in tip top shape.

Tire Maintenance

Tire maintenance is also a cornerstone of EV care. Checking tire pressures regularly, ideally every month, ensures your tires are properly inflated. Proper inflation reduces rolling resistance and maximizes your driving range. Tire rotation is equally critical. Rotating tires every 10,000 to 12,000 kilometers helps them wear evenly and extend their serviceable life. Making sure your wheels are properly aligned eliminates unnecessary strain and prevents uneven tread wear which contributes to a smoother & safer drive. It's advisable to have your vehicle's alignment checked at least annually, or whenever you notice the car pulling to one side or vibrations at higher speeds.

Software & Electronics

Today's EVs are also sophisticated, software-driven machines, meaning that regular updates are essential. These updates control everything from battery performance to safety systems and navigation. Additionally, the electronic systems in your EV, including the sensors, cameras, and driver-assist technologies, should be in good working order, and can be checked during regular servicing.

Other Tips

Another aspect that shouldn't be overlooked is the condition of your charging equipment. Cables, connectors, and home charging stations need to be free of wear or damage to ensure safe and reliable charging. Regular washing of your EV, particularly the areas where sensors and cameras are placed, helps maintain the proper function of safety features such as parking assistance and lane departure alerts.

By focusing on these areas, you can enjoy lower running costs, a high level of dependability, and years of enjoyable, eco-friendly driving. A proactive approach to maintenance is key to a reliable and efficient EV ownership experience.
