Maintaining Your Used EV: Essential Tips
Purchasing a used electric vehicle (EV) is a smart move for both your wallet and the environment. However, like any vehicle, regular maintenance is crucial to ensure its longevity and optimal performance. While EVs generally require less maintenance than their petrol-powered counterparts, neglecting key areas can lead to costly repairs down the line. This guide provides essential tips for maintaining your used EV and keeping it in top condition. You can also learn more about Usedelectricvehicles and what we offer.
1. Regular Battery Health Checks
The battery is the heart of your EV, and its health directly impacts the vehicle's range and performance. While EV batteries are designed to last for many years, degradation is inevitable. Regular monitoring can help you identify potential issues early on.
Understanding Battery Degradation
Battery degradation refers to the gradual loss of battery capacity over time. Factors contributing to degradation include:
Age: All batteries degrade naturally with age.
Usage: Frequent fast charging and deep discharges can accelerate degradation.
Temperature: Extreme temperatures (both hot and cold) can negatively impact battery health.
Monitoring Battery Health
Check the State of Health (SOH): Many EVs provide a State of Health (SOH) reading, which indicates the battery's current capacity as a percentage of its original capacity. Consult your owner's manual for instructions on accessing this information.
Track Range: Monitor your vehicle's range over time. A noticeable decrease in range could indicate battery degradation.
Use Diagnostic Tools: Some aftermarket diagnostic tools can provide more detailed information about your battery's health.
Best Practices for Battery Care
Avoid Extreme Charging Habits: Limit frequent fast charging and try to keep the battery charge between 20% and 80% for daily use. Full charges are fine for long trips, but avoid leaving the battery at 100% for extended periods.
Manage Temperature: Park your EV in shaded areas during hot weather and in a garage during cold weather to minimise temperature extremes.
Follow Manufacturer Recommendations: Adhere to the manufacturer's recommendations for battery care and maintenance.
2. Tyre Maintenance and Rotation
Tyres play a crucial role in your EV's handling, efficiency, and safety. Proper tyre maintenance is essential for maximising their lifespan and ensuring optimal performance.
Tyre Pressure
Check Regularly: Check your tyre pressure at least once a month and before long trips. Use a reliable tyre pressure gauge.
Maintain Correct Pressure: Inflate your tyres to the recommended pressure specified in your owner's manual or on the tyre placard (usually located on the driver's side doorjamb). EVs often have different recommended pressures than petrol cars due to their weight.
Avoid Over- or Under-Inflation: Over-inflated tyres can lead to a harsh ride and reduced grip, while under-inflated tyres can increase rolling resistance and reduce range.
Tyre Rotation
Rotate Regularly: Rotate your tyres every 8,000 to 10,000 kilometres, or as recommended by the manufacturer. This helps to ensure even wear and extend the lifespan of your tyres.
Follow Rotation Pattern: Consult your owner's manual for the recommended tyre rotation pattern for your vehicle. Common patterns include front-to-back and X-pattern rotations.
Tyre Condition
Inspect for Wear: Regularly inspect your tyres for signs of wear, such as uneven tread wear, cracks, or bulges.
Check Tread Depth: Use a tread depth gauge to measure the tread depth. Replace your tyres when the tread depth reaches the minimum legal limit (usually 1.6mm).
Consider Low Rolling Resistance Tyres: When replacing your tyres, consider choosing low rolling resistance tyres, which are designed to improve energy efficiency and increase your EV's range. You can find more information in our frequently asked questions.
3. Brake System Inspection
EVs utilise regenerative braking, which significantly reduces wear on the traditional friction brakes. However, the brake system still requires regular inspection and maintenance.
Regenerative Braking and Brake Wear
Regenerative braking uses the electric motor to slow the vehicle down, converting kinetic energy back into electricity and charging the battery. This reduces the reliance on friction brakes, resulting in significantly less wear and tear.
Inspection Points
Brake Pads and Rotors: Although they wear down slower, regularly inspect the brake pads and rotors for wear and damage. Listen for any unusual noises, such as squealing or grinding, when braking.
Brake Fluid: Check the brake fluid level and condition. Brake fluid absorbs moisture over time, which can reduce its effectiveness. Replace the brake fluid according to the manufacturer's recommendations.
Brake Lines and Hoses: Inspect the brake lines and hoses for leaks, cracks, or damage. Replace any damaged components immediately.
Addressing Infrequent Use
Because regenerative braking handles much of the slowing, the physical brakes can sometimes develop rust or corrosion from infrequent use. Periodically performing hard braking (in a safe environment) can help to clean the rotors and prevent this issue.
4. Fluid Level Checks
While EVs don't require oil changes like petrol cars, they still have several fluids that need to be checked and maintained.
Coolant
Battery Coolant: Many EVs use coolant to regulate the temperature of the battery pack. Check the coolant level regularly and top it up as needed. Use the coolant specified by the manufacturer.
Motor Coolant: Some EVs also have a separate coolant system for the electric motor. Check the coolant level and condition periodically.
Brake Fluid (Refer to Brake System Inspection Section)
As mentioned earlier, brake fluid levels and condition should be checked regularly.
Windscreen Washer Fluid
Keep the windscreen washer fluid reservoir filled to ensure clear visibility. Use a quality windscreen washer fluid that is suitable for your climate.
Transmission Fluid (If Applicable)
Some EVs have a single-speed transmission that requires fluid changes. Consult your owner's manual for the recommended service interval.
5. Software Updates
EVs rely heavily on software to control various functions, including battery management, motor control, and infotainment. Regular software updates are essential for improving performance, fixing bugs, and adding new features.
Over-the-Air (OTA) Updates
Many modern EVs support over-the-air (OTA) software updates, which can be downloaded and installed wirelessly. Ensure your vehicle is connected to Wi-Fi and follow the on-screen instructions to install updates.
Dealership Updates
Some software updates may require a visit to the dealership. Check with your dealer for any available updates and schedule an appointment as needed.
Benefits of Software Updates
Improved Performance: Software updates can optimise battery management, motor control, and other systems to improve performance and efficiency.
Bug Fixes: Updates can address software bugs and glitches that may affect the vehicle's functionality.
New Features: Software updates can add new features and functionalities to your EV.
Security Enhancements: Updates can improve the vehicle's security and protect against cyber threats.
6. Cleaning and Detailing
Keeping your EV clean not only enhances its appearance but also helps to protect its paint and finish. Regular cleaning and detailing can prevent corrosion and maintain the vehicle's resale value.
Washing
Wash Regularly: Wash your EV regularly to remove dirt, grime, and road salt. Use a pH-neutral car wash soap and a soft sponge or wash mitt.
Avoid Harsh Chemicals: Avoid using harsh chemicals or abrasive cleaners, which can damage the paint and finish.
Rinse Thoroughly: Rinse the vehicle thoroughly with clean water to remove all traces of soap.
Waxing and Polishing
Wax Periodically: Apply a coat of wax every few months to protect the paint and give it a glossy shine.
Polish as Needed: Polish the paint as needed to remove scratches and swirl marks.
Interior Cleaning
Vacuum Regularly: Vacuum the interior of your EV regularly to remove dirt, dust, and debris.
- Clean Surfaces: Clean the interior surfaces with a suitable cleaner. Use a leather cleaner for leather seats and a vinyl cleaner for vinyl surfaces.
