Battery Voltage and Distance
Equipment
- Final AEV design
- Voltage multimeter
- Li-Po Battery
Method
*Use fully charged battery
1. First the battery voltage was measured and recorded
2. Then the code was run at 50% power
3. Then the battery voltage was measured and recorded
4. Then the code was run at 50% again
5. Then the battery voltage was measured and recorded
6. Then the code was run at 25% power
7. Then the battery voltage was measured and recorded
8. Then the code was run at 25% again
9. Then the battery voltage was measured and recorded
10. Then the code was run at 75% power
11. Then the battery voltage was measured and recorded
12. Then the code was run at 75% again
13. Finally the battery voltage was measured and recorded
Code for aR&D 3
motorSpeed(4,XX); // XX is replaced by 25, 50, and 75 for the different tests
goFor(20);
brake(20);
Takeaways
The purpose of aR&D 3 was to build off of aR&D 2 and to see how voltage drains. We hypothesized that voltage would scale linearly and found that at 25% power around 0.02V were lost, at 50% power 0.04V volts were lost and at 75% power 0.06V were lost. In order to get more accurate data a multimeter that reads to 0.001V would be best.
