Typically, electric vehicle drivers would charge their car to between 20% and 80%. Like a mobile phone, charging is quickest for the first 20% and once it reaches 80%, it slows down to protect the battery life. Drivers can also influence the lifespan of a battery by charging up to 80%. For example, AC charging is often better for batteries than DC rapid charging, hence, when using rapid chargers, charge the battery up to 80% instead of 100% which will also help protect its lifespan. We recommend you set your charging target to 80% for your vehicle.
The same could be set up on the MMI (in your vehicle's MMI select home screen > Car > Charging and efficiency > Charging.) For longer journeys, we recommend you to set your charging target to 100%, as it generates the longest range.
