Table 3.1, located below, shows the battery voltage at the beginning of the lab.

Table 3.1: Battery Pack Functional Test Measured (V) Expected
Initial Battery Voltage 9.540 9-10 VDC

The initial battery voltage was recorded as 9.540 volts, a number greater than 9.00 volts, indicating that the battery was almost fully charged.

Table 3.2, located below, shows the battery pack characterization. The table shows the voltage of the battery and the current through the battery as a function of time.

Table 3.2: Battery Pack Characterization
Minutes under charge Battery Voltage (V) Battery Current (A)
0 9.540 0.120
1 9.548 0.114
2 9.586 0.107
3 9.605 0.100
4 9.624 0.095
5 9.642 0.091

The above table shows that the current through the battery decreases …show more content…

The data in table 3.6 follows these trends; therefore, the EPS board was functioning as …show more content…

The SPV and SPI will further decrease when the lamp is turned off. The reasoning behind this trend is an angle of 45 degrees lets both solar panels receive light from the halogen lamp, so this data point will have the largest SPV and SPI measurement. Turning the EyasSAT module normal to one solar panel means that only one solar panel is receiving light so the SPV and SPI decrease. Turning off the halogen lamp means neither of the solar panels are receiving light so the SPV and SPI values decrease even further. The data in table 3.7 follow this expected trend, so the solar panels functioned as
