Kia e-Niro 2019 – Lock command issue / implausible CAC & SOH values

Hello,

I recently installed an OVMS module in my 2019 Kia e-Niro and overall it works quite well.
SOC, GPS position and most vehicle data are working correctly.

However, I noticed two issues:

1. Lock command problem

• Unlock command via OVMS works correctly.
• Lock command does not work correctly.
• Every time I try to lock the vehicle via OVMS:
  • the radio powers on
  • the vehicle attempts to lock
  • locking fails and the car remains unlocked

2. CAC and SOH values appear implausible

The reported battery values do not seem realistic:

• CAC values are sometimes reported above 100 Ah
• SOH is always shown as 100%
• An independent battery health certificate reports approximately 93.6% SOH

Vehicle mileage is approximately 151,000 km.

Example:

• OVMS reported CAC values up to around 114 Ah

Questions:

• Is this a known issue in the Kia Niro EV module?
• Are CAC and SOH directly read from the BMS or estimated/calculated by OVMS?

OVMS firmware:

• 3.3.004
• Kia module version: xkn 0.1.6

Thanks.
