Abstract
The present invention provides a system for monitoring usage of a electric vehicle's battery which offsets the display when the vehicle is in an on condition. A battery energy measuring device is provided which measures the conditions indicative of the maximum available current of the battery and generates a charge signal indicative of the conditions indicative of the maximum available current of the battery. A display is provided which is responsive to the charge signal for displaying the maximum available current of the battery. An offset device is provided which is responsive to the keyswitch to provide a keyswitch signal to the battery energy measuring device representative of the on and off condition of the keyswitch. The battery energy measuring device offsets the charge signal when the keyswitch is in an on condition such that the display displays the on and off condition of the keyswitch.
