Measurer for performance of electric car

Abstract

Abstract PURPOSE:To enhance the measurement precision, by selecting various inputted signals in accordance with required measurement items and performing automatically data gathering, analysis, operations such as editing, and processings and outputting results to a printer. CONSTITUTION:When a P signal (power) or a B signal (brake) of the main controller input is inputted from an insulating relay buffer 5 after completion of setting-up, measurements for the speed, the distance, the time, the average aerial wire voltage, the current of main circuit, the acceleration and deceleration speed, and the electric energy are started from this time, and results are printed on a printer 19 at intervals of a set time. In the P or B test mode, sampling is started by the P or B signal inputted from the buffer 5 or a P or B simulation signal input, and an acceleration alpha and deceleration beta at a certain time are calculated and are stored. Measured results are outputted automatically to the printer 19, and contents of an internal memory 18 are cleared to terminate measurements.
