2.2.3 Verifying SOH Function

  1. Keep the setup as similar to steps 1-6 in Section 2.2.1.
  2. Go to GUI SOH Settings page, set Enable AVI Pin Output to Battery voltage and set AVI Pin Ratio To The Backup Battery Voltage as 1/2 with GUI.
  3. Set Charger, SOH as Enable SOH. Check if the AVI pin voltage is approximately 1.5V.
  4. Set SOH Discharge Current to 500mA with GUI and check if the battery simulator is discharged by approximately 500mA.
  5. Set Enable AVI Pin Output to Discharge Current and check if the AVI pin voltage is approximately 0.5V.
