1. A method performed in an electronic device for managing a power limit of a battery of a vehicle, the method comprising:
obtaining a first State of Health value of the battery at a first time,
obtaining a second State of Health value of the battery at a second time,
determining a rate of change of State of Health value of the battery based on the first State of Health value of the battery at the first time and the second State of Health value of the battery at the second time,
determining a power value by calculating a function that is dependent on the rate of change of State of Health of the battery, and
adjusting the power limit of the battery to the determined power value for managing the life time of the battery, and
wherein adjusting the power limit to a lower power limit is ignored after detecting input from a driver of the vehicle accepting a shortening of the lifetime of the battery.
