Battery Testing
Goal:
The team was asked to determine the relationship between battery voltage and the number of test runs and improved the efficiency and design of the AEV project.
Procedure:
1. Run the reflectance sensor test to make sure the performance of AEV is correct.
2. The group will use the same scenario code from L_M_Preliminary Lab and revise i
3. The group will put the AEV on the same track for all the runs.
4. After each run, the group will use the battery voltage multimeter to record the voltage of the battery.
5. After finishing the data collection by using the data extraction tool, the group will plot the graph of voltage vs. the number of runs and analyze the data.
Equipment needed:
1. Constructed AEV + LI-PO Battery/Batteries
2. Battery Voltage Multimeter
Graph: 
Results: The figure Battery Voltage vs. Numbers of Runs demonstrates that the voltage of the battery is directly proportional to the number of runs. When the number of runs increases, the voltage will slightly decrease. After each run, the battery voltage decreases about 0.01 watts to 0.02 watts. It is admitted that the increased number of runs will lower the battery voltage. However, since the reduced amount is small enough, it will not significantly affect the overall performance. Although it is not necessary to change the design of the AEV, to achieve the best performance, the team should charge the battery before performance testing.
