How to Preserve Your Electric Vehicle Battery During Long-Term Storage
Electric vehicles (EVs) are becoming increasingly popular, but proper battery care is crucial, especially during extended storage periods. Here’s how to safeguard your EV’s battery and ensure optimal performance when you’re ready to hit the road again:
Optimal Charge Level:
Avoid Extremes: A fully charged or wholly depleted battery is ideal for long-term storage. Extreme charge states can accelerate battery degradation.
The Goldilocks Zone: Aim for a moderate charge level, typically between 40% and 60%. Consult your vehicle’s owner’s manual for specific recommendations.
Consider a Battery Maintainer: Consider using a battery maintainer for extended storage. These devices trickle charge the battery to maintain a consistent level, preventing deep discharge.
Temperature Control:
Cool is Key: High temperatures significantly accelerate battery degradation. Store your EV in a cool, shaded area whenever possible.
Avoid Direct Sunlight: Direct sunlight can cause excessive heat buildup within the battery pack.
Consider a Garage: Storing your EV in a garage provides a more temperature controlled environment.
Minimize Electrical Drains:
Disconnect Accessories: Disconnect accessories that may draw power from the 12-volt battery, such as dashcams or chargers
Disable Features: Disable any unnecessary features like keyless entry or remote start, as these can gradually drain the battery.
Regular Check-ups:
Monthly Inspections: Perform brief checks on the battery’s state of charge during storage. This helps to identify any unexpected issues.
Consult Your Dealer: For extended storage periods (several months or more), consult your EV dealer for specific recommendations and potential maintenance procedures.
Consider Climate-Controlled Storage:
For Long-Term Storage: Consider climate-controlled storage facilities if you anticipate storing your EV for an extended period. These facilities offer consistent temperature and humidity levels, providing optimal conditions for battery health.
Important Notes:
Consult Your Owner’s Manual: The owner’s manual contains your vehicle’s most accurate and up-to-date storage instructions.
Manufacturer Recommendations: Follow any specific recommendations from your EV manufacturer regarding storage procedures and battery maintenance.
Following these guidelines, you can significantly minimize battery degradation during long-term storage and ensure your EV can perform optimally when you’re ready to drive again.
