A system for providing a scale (11) of electrical charge of a vehicle battery and a hybrid vehicle comprising such a system comprises a scale (11) of state of charge of the vehicle battery. The scale (11) comprises minimum (14) and maximum (15) parameters and a controller to select the minimum (14) and maximum (15) parameters if the scale (11) in dependence on a battery usage parameter dependent on at least one of a mode of operation of the vehicle, a state of charge of the battery and a state of health of the battery. A display (10) for indicating an amount consists of the scale (11) and an indicator (12) movable with respect to the scale (11). Different scales (11) are provided for different purposes, and are changeable without altering the instant position of the indicator (12). The display (10) may indicate the state of charge of a battery of the hybrid electric vehicle having an internal combustion engine and motor/generator, different scales (11) having maxima (15) corresponding to different nominal or optimum states of charge. |
