hitl_tester.test_cases.bms.test_korad_charge

Test Korad power supply logging and control functionality.

Used in these test plans:

  • nicd_charge ⠀⠀⠀(bms/nicd_charge.plan)

Example Command (warning: test plan may run other test cases):

  • ./hitl_tester.py nicd_charge -DSAMPLE_RATE=2 -DVOLTAGE=3 -DCURRENT=0.5
