Charging at Charging Stations for Range Extension
First Claim
1. A control unit for a vehicle that is driven by an electric motor with electrical energy from an electrical energy store, comprising:
- a processor configured to execute processing to;
determine a first state of charge of the energy store at a starting position of the vehicle;
determine a first range of the vehicle starting from the starting position based on the first state of charge;
determine that the first range of the vehicle is insufficient to travel to a destination position of the vehicle;
based on a second state of charge of the energy store and based on the first range, determine a charging region between the starting position and the destination position, wherein the second state of charge corresponds to an assumed state of charge of the energy store after carrying out a charging process at a charging location on a route between the starting position and the destination position; and
determine one or more possible charging locations in the charging region based on digital map information.

Abstract
A method and a corresponding device are provided for extending the range of vehicles having an electric drive. A control unit for a vehicle that is driven by an electric motor, which is operated by electrical energy from an electrical energy store, is described. The control unit is designed to determine a first state of charge of the energy store at a starting position of the vehicle and to determine a first range of the vehicle starting from the starting position on the basis of the first state of charge. Furthermore, the control unit is designed to determine that the first range of the vehicle is insufficient for reaching a target position of the vehicle. The control unit is also designed to determine a changing region between the starting position and the target position on the basis of a second state of charge of the energy store and on the basis of the first range. The second state of charge corresponds to an assumed state of charge of the energy store after a charging process is carried out at a charging location on a route between the starting position and the target position. In addition, the control unit is designed to determine one or more possible charging locations in the charging region on the basis of digital map information.
