How do I maintain my Ford Electric Vehicle's battery?

Follow the Electric Vehicle (EV) battery maintenance tips below to keep your battery healthy.

Stay in Charge

Similar to the fuel gauge found in a typical gas-powered vehicle, your battery charge and health are important to know how far you can go between fill-ups.

The high-voltage battery gauge displays the state of charge in the form of a gauge or percentage. A full fill (or 100% charge) represents the total amount of energy you can get from your vehicle without plugging in. When your gauge is blue, you have miles to go. When the gauge turns amber, your battery is low, and it’s time to plug in. When the battery is depleted, the gauge is red.

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 to help preserve your battery life.

Overnight Charging and Storage

You can increase the longevity of your high-voltage battery by using the Preferred Charge Times feature. Preferred Charge Times can keep your battery at the optimal temperature and state of charge based on your settings and usage. Allowing your battery to cool before charging and setting the maximum state of charge to 90% for everyday usage will improve the longevity of your high-voltage battery.

Storage Temperature

Storing your vehicle in temperatures between 32.0 °F and 112.9 °F is the most beneficial for the high-voltage battery.

Storage State of Charge

You can increase the battery life by maintaining your state of charge below 100%. When your vehicle will be parked for an extended period of 30 days or more, we recommend your battery be at 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.
