Device for determining cost-optimized charging of electric car based on navigation data, has charge determining device determining required charging of battery of car to reach destination based on battery charge state and navigation data

摘要

The device has a battery (1) including a charge state output device for outputting charge state of the battery. A navigation system (2) includes an energy calculating device (22) for calculating energy requirements of an electric vehicle i.e. car, based on navigation data. An energy management system (3) includes a charge determining device (31) to determine required charging of the battery of the electric car to reach a target destination based on the charge state of the battery and the navigation data. An independent claim is also included for a method for determining cost-optimized charging of an electric vehicle based on navigation data.
