Battery degradation can be a common issue affecting the range of electric vehicles like the 2018 Chevrolet Bolt EV. Addressing this problem involves a few steps and considerations to help maximize the battery life and ensure optimal performance. Here is a detailed guide on how to approach this issue:

 
Understand Battery Degradation
 

• • Batteries naturally degrade over time due to various factors, including temperature, usage patterns, and age. It’s essential to understand that some level of degradation is inevitable.
• • Monitor your vehicle's range and consult the vehicle's instrument panel regularly to gauge if the battery's state of health is significantly impacting the range.

 
Optimize Charging Habits
 

• • Avoid frequent full charges or discharges. Aim to keep the battery charge level between 20% and 80% for daily use, which can help extend battery life.
• • Utilize Level 1 or Level 2 charging options for regular charging as fast charging (DC fast chargers) can increase battery temperature, potentially accelerating degradation.
• • Charge the vehicle overnight or during cooler periods of the day to minimize the effects of high temperatures on battery lifespan.

 
Maintain Optimal Temperature
 

• • Extreme temperatures can impact battery performance. If possible, park your Chevrolet Bolt EV in a garage or shaded area to protect it from extreme heat or cold.
• • Utilize the vehicle's thermal management system to maintain optimal battery temperatures, especially during longer drives or in severe climate conditions.

 
Regular Software Updates
 

• • Ensure that your vehicle’s software is up-to-date. Chevrolet periodically releases updates that may improve battery performance and range estimations.
• • Contact your local Chevrolet dealer or service center for available updates, as they may enhance battery management systems.

 
Conduct Routine Maintenance
 

• • Regular maintenance checks ensure that the vehicle is in good operating condition, which indirectly supports battery health.
• • Verify that the cooling system functions correctly to prevent battery overheating and ensure all software updates are installed.
• • Have the battery assessed by professionals if you notice a significant decline in range, as it might indicate a specific issue beyond typical degradation.

 
Consider Warranty and Replacement Options
 

• • The 2018 Chevrolet Bolt EV comes with a battery warranty; check if your battery issues fall under warranty coverage.
• • If degradation is substantial and beyond warranty, evaluate the cost-benefit of battery replacement or consulting Chevrolet for potential solutions.

By understanding these factors and taking the appropriate steps, you can help mitigate the impact of battery degradation on your Chevrolet Bolt EV and preserve its efficiency for a longer duration.
