Abstract
The invention relates to controlling the energy output from an electric vehicle to an external consumer. According to the invention, an energy requirement for reaching a predefined destination or along a predefined route is determined. If the electrical energy stored in the traction battery falls to a critical level, which is required for safely reaching the destination, then the energy output to an external consumer can be stopped. Alternatively, a user can be informed at least of a critical status of this type.
Claims10
A control device (11) for an electric vehicle (1) having a traction battery (12) and an energy output device (13) for providing electrical energy to an external consumer (2), wherein the control device (11) is configured:
- to determine the current state of charge of the traction battery (12),
- to determine an energy requirement for a future route,
- to compare the state of charge of the traction battery (12) and the determined energy requirement for the future route, and
- to use the comparison of the state of charge of the traction battery (12) and the determined energy requirement to control an energy output to the external load (2) and/or to output a signal.
A method for controlling the energy outputs from a traction battery (12) of an electric vehicle (1) to an external load (2), the method comprising:
- determining (S1), via a control device, an energy requirement of the electric vehicle (1) for a future route;
- determining (S2), via the control device, a current state of charge of the traction battery (12);
- comparing (S3), via the control device, the state of charge of the traction battery (12) with the determined energy requirement for the future route;
- and
- outputting (S4), via the control device, of a signaling and/or control of an energy output to the external load (2) using the comparison of the state of charge of the traction battery (12) with the determined energy requirement.
