ELECTRIC VEHICLE BATTERY FAST CHARGING val is 100 miles. With a 332 lbs passenger or equivalent weight, the vehicle travels 35 miles between any two charging segments. During this driving test, the values noted include: • • • •
Average Average Average Average
vehicle speed distance required between charge distance traveled between charge kWhr available per charge
Driving Range at the End of Day-2 Test The vehicle driving range test is to determine the maximum driving range achieved at the end of Day-2 during a 12-hour period. The test is repeated with the same passenger weight and minimum range requirements as on Day-1. The same driving test values are noted during the test on Day-2.
Driving Range at the End of Day-3 Test The test is repeated with the same passenger weight and minimum range requirements as on Days-1 and -2. The same driving test values are noted during the test on Day-3.
ELECTRIC VEHICLE SPEEDOMETER CALIBRATION In the event the EV speedometer requires recalibration, the vehicle requires a data acquisition system. The speedometer can be recalibrated using the following steps: • • •
•
•
•
Record the speedometer reading when the EV is stopped. Accelerate the EV to 5 mph and record the speedometer reading. Increase the EV speed in increments of 5 mph and note the speedometer readings until the final speed of 60 mph is achieved. Increase the EV speed to 80 mph and note the speedometer reading. Develop a speedometer calibration table, taking differences in the speedometer reading and the calculated correction factors into account. Using this speedometer calibration table, repeat the test with a recalibrated speedometer.
