Abstract

A controller (100) for a vehicle (1), the vehicle comprising:

a powertrain (1P) comprising an electric machine (50) for providing motive power;cooling means (60, 80); andelectrical energy storage means (70) for powering the electric machine (50),wherein the cooling means (60, 80) is configured to cool the electrical energy storage means (70) and a cabin (1C) of the vehicle and the vehicle (1) is configured to operate in a first or second driving mode,the controller (100) comprising:an input for receiving information indicative of a temperature of the energy storage means (70); anda processor arranged to generate a control signal in dependence on the information indicative of temperature of the energy storage means (70) and information indicative of the selected driving mode of the vehicle,wherein:if the vehicle is in the first driving mode the processor is configured to generate the control signal to limit or reduce an amount of power consumed by the powertrain (1P) in dependence on the information indicative of temperature of the energy storage means (70); and/orif the vehicle is in the second driving mode the processor is configured to generate the control signal to control a proportion of the cooling power of the cooling means that is available to cool the electrical energy storage means relative to the cabin (1C) of the vehicle (1) in dependence on the information indicative of temperature of the energy storage means (70).
