Functional Tests

4.1 Electrical Power System (EPS)

Test Plan

For this section the intention is to write down at least what should be tested on the EPS engineering model. Details on how this tests have been done will be given in the next section. Below follows the list of EPS blocks which must be tested:

• Continuity, for the case that the security switches are closed.

• Input current, for the case that any solar panel or a test bench power supply is connected (instrument measurement).

• Input current, for the case that any solar panel or a test bench power supply is connected (microcontroller adc measuremnt).

• Battery input current (instrument measurement).

• Battery voltage (instrument measurement).

• Battery output current for a known electrical load (instrument measurement).

• Temperature measurement (battery monitoring IC output).

• Battery input current (battery monitoring IC output).

• Battery voltage (battery monitoring IC output).

• Battery output current for a known electrical load (battery monitoring IC output).

• Turn on/off mppt blocks (hardware shutdown).

• Turn on/off mppt blocks (software shutdown).

• Battery overvoltage protection.

• Battery overcurrent protection.

• Battery undervoltage protection.

• Battery charging modes for different voltage thresholds.

• Turn on/off dc/dc converters (hardware shutdown).

• Turn on/off dc/dc converters (software shutdown).

• EPS actuation by receiving commands via I2C.
