Abstract
A method of controlling a range extender of an electric vehicle comprises using actual measured or modelled pollution levels dynamically to set a target state of charge level for a range extender of an electric vehicle at a particular location.
Claims20
A method of controlling a range extender of an electric vehicle, the method comprising:
- using actual measured or modelled pollution levels dynamically to set a target state of charge level for a range extender of an electric vehicle at a current location of the electric vehicle,
- wherein using actual measured pollution levels comprises measuring a dynamic level of pollution at the current location of the electric vehicle using one or more sensors arranged on the electric vehicle, and
- wherein using modelled pollution levels comprises:
- generating a dynamic model of pollution;
- and
- using the generated dynamic model to calculate the modelled pollution level at the current location of the electric vehicle at a current or future point in time;
- monitoring a state of charge of an on-board battery powering the electric vehicle;
- and
- activating the range extender in response to the state of charge being lower than the target state of charge level.
An apparatus for controlling a range extender of an electric vehicle, the apparatus being configured to perform operations comprising:
- using actual measured or modelled pollution levels dynamically to set a target state of charge level for a range extender of an electric vehicle at a current location of the electric vehicle,
- wherein using actual measured pollution levels comprises measuring a dynamic level of pollution at the current location of the electric vehicle using one or more sensors arranged on the electric vehicle, and
- wherein using modelled pollution levels comprises:
- generating a dynamic model of pollution;
- and
- using the generated dynamic model to calculate the modelled pollution level at the current location of the electric vehicle at a current or future point in time;
- monitoring a state of charge of an on-board battery powering the electric vehicle;
- and
- activating the range extender in response to the state of charge being lower than the target state of charge level when the electric vehicle.
A non-transitory computer readable medium storing software code for controlling a range extender of an electric vehicle, wherein execution of the software code on a data processing apparatus causes the data processing apparatus to perform operations comprising:
- using actual measured or modelled pollution levels dynamically to set a target state of charge level for a range extender of an electric vehicle at a current location of the electric vehicle,
- wherein using actual measured pollution levels comprises measuring a dynamic level of pollution at the current location of the electric vehicle using one or more sensors arranged on the electric vehicle, and
- wherein using modelled pollution levels comprises:
- generating a dynamic model of pollution;
- and
- using the generated dynamic model to calculate the modelled pollution level at the current location of the electric vehicle at a current or future point in time;
- monitoring a state of charge of an on-board battery powering the electric vehicle;
- and
- activating the range extender in response to the state of charge being lower than the target state of charge level.
