As temperatures rise during the summer months, electric vehicle (EV) owners face unique challenges in maintaining their vehicles’ performance and longevity. High heat can impact battery efficiency, reduce driving range, and strain various vehicle systems. Implementing proactive maintenance strategies is crucial to ensure your EV remains reliable and efficient throughout the season.
1. Monitor and Manage Battery Temperature
EV batteries operate optimally within a specific temperature range, typically between 15°C and 25°C. Excessive heat can lead to battery degradation, reduced efficiency, and shortened lifespan.
Tips:
- Park in shaded areas or garages to minimize direct sun exposure.
- Avoid charging during peak heat hours; opt for early morning or late evening sessions.
- Utilise your EV’s thermal management system, which many modern vehicles have to regulate battery temperature automatically.
Implementing these practices helps maintain battery health and ensures consistent performance.
2. Optimise Charging Practices
Charging your EV in high temperatures can lead to longer charging times and potential thermal throttling.
Recommendations:
- Schedule charging during cooler periods, such as overnight, using smart charging features.
- Avoid frequent use of fast-charging stations in extreme heat, as they can accelerate battery wear.
- Maintain the battery charge between 20% and 80% to prolong battery life.
These strategies help in preserving battery efficiency and extending its lifespan.
3. Precondition Your Vehicle
Preconditioning involves cooling or heating your EV’s cabin while it’s still plugged in, using grid power instead of the vehicle’s battery.
Benefits:
- Enhances driving comfort by achieving a pleasant cabin temperature before departure.
- Conserves battery power, as the energy used for preconditioning doesn’t come from the battery.
How to Precondition:
- Use your vehicle’s app or onboard system to set the desired cabin temperature.
- Activate preconditioning 15–30 minutes before driving, ensuring the vehicle is still connected to the charger.
Regular use of preconditioning can lead to significant energy savings and improved driving comfort.
4. Maintain Proper Tyre Pressure
High temperatures can cause tyre pressure to fluctuate, impacting vehicle handling and efficiency.
Action Steps:
- Check tyre pressure regularly, especially during temperature changes.
- Inflate tyres to the manufacturer’s recommended levels, which can typically be found in the owner’s manual or on a sticker inside the driver’s door.
Proper tyre maintenance ensures optimal contact with the road, enhancing safety and performance.
5. Regularly Inspect Cooling Systems
Your EV’s cooling system plays a vital role in maintaining battery storage and system temperatures.
Maintenance Tips:
- Check coolant levels periodically, ensuring they are within the recommended range.
- Inspect for leaks or signs of wear in hoses and connections.
- Schedule regular servicing to ensure the cooling system operates efficiently.
A well-maintained cooling system prevents overheating and protects critical components.
By implementing these summer maintenance tips, you can ensure your electric vehicle remains efficient, safe, and comfortable throughout the hot months. Regular attention to battery health, charging practices, and overall vehicle maintenance not only enhances performance but also extends the lifespan of your EV.
