When using the battery at a low state of charge, your vehicle could start disabling accessory features to protect battery life.
If your vehicle reaches a 0% state of charge, recharge your vehicle as soon as possible.
In everyday use it is acceptable to use the full state of charge window, however there are a few best practices we recommend in order to maintain the health and life of your battery.
Overnight Charging
You can increase the longevity and performance of your high voltage battery by using the charge scheduling and departure and comfort settings on your touchscreen or in the FordPass app.
With Charge Scheduling, you can improve the high voltage battery's longevity by delaying the start of charging and setting a maximum charging limit. We recommend you set your preferred charging times to be at least 2-3 hours after your typical plug in time. This allows the battery to cool before charging begins. Additionally, setting the maximum charge level to be less than 100% for everyday usage reduces strain on the battery.
You can improve driving range and performance by scheduling departure times and cabin comfort level with the Departure and Comfort feature. This not only warms or cools the cabin but also conditions the battery to ensure the best driving range and performance by the set departure time.
DC Charging
Frequent use of DC charging could result in reducing your battery's efficiency and lifespan. This is more pronounced on the standard range battery pack versus the extended range battery pack.   See   What is DC Charging
Storage Temperature
Storing your vehicle in temperatures between 32°F (°C) and 113°F (45°C) is the most beneficial range for the high voltage battery.
At temperatures just above the freezing point or lower, plug in your vehicle to maintain battery performance and maximize driving range.
Storage State of Charge
You can increase the battery life by maintaining your state of charge below 100%. When you park your vehicle for an extended period of 30 days or more, we recommend your battery be at an approximately 50% state of charge. Storing your vehicle's high voltage battery at higher states of charge is less favorable than storing at lower states of charge.
Note:   To achieve this state of charge for storage, you can drive your vehicle down to 50% and set a charge limit for your location.  See   Setting the Charging Schedule and Preferences
