Abstract
An Electric Vehicle Monitoring System (EVMS) for measuring the performance f an electric vehicle. The preferred embodiment of the system comprises: (1) a variety of sensors for obtaining data on vehicle performance and operating parameters; (2) a digital dashboard display providing the vehicle operator with information on vehicle operating parameters; (3) a data acquisition system for collecting the data from the sensors and converting the data to digital format; and (4) a processing unit in the form of a removable, portable or notebook computer used for storing, evaluating and providing reports of the digital format data. The EVMS is adapted for use in a vehicle specifically designed for electric propulsion or for use in an internal combustion engine vehicle converted to electrical power use. The sensors include voltmeters, ammeters, thermocouples, optical shaft encoders and an inclinometer and provide data to both the operator display and the data acquisition system. The operator display includes bargraphs for current draw, motor and battery temperature, accessory battery voltage, main battery voltage or 'fuel level' and alphanumeric displays for vehicle speed, distance traveled, trip meter and transmission gear indicator.
