  • Performance monitor for electric vehicle
    Patent number: 5568052
    Abstract: A system (10) and method for monitoring usage of current immediately available from the traction batteries (12) of an electric vehicle includes a means (18) for generating a signal representative of the current being drawn from the batteries (12); a means (20) for generating a signal representative of the maximum current available from the batteries (12) for immediate use; and a means (22) responsive to the drawn-current signal and the maximum-available-current signal for generating a usage signal representing the ratio of drawn current to maximum-available current. A display, such as an analog meter (24) responsive to the usage signal and calibrated from zero-percent to one-hundred-percent available current usage, displays the transitory current usage as a percentage of maximum-available current.
