The amount of voltage across the battery decreases at about a constant rate per run. The distance that the AEV travels is also dependent on the amount of voltage that is in the battery. As seen in the second graph, when there is more voltage in the battery, the AEV travels farther.
These takeaways mean that in the future for the MCR, the team should keep in mind that the voltage across the battery is decreasing between runs so the energy provided to the motors will decrease over a number of runs. Since the distance the AEV travels is also dependent on the voltage, this means that over a number of runs, the distance traveled by the AEV will also decrease. In order for the runs to be accurate, the battery should be changed after a period of time to ensure that the difference in battery voltage does not introduce a skew in performance tests.
