Interpreting OBD2 Data: Key Observations for Kia Sportage PHEV Battery

Analyzing the data provided by the Car Scanner app can reveal valuable insights into your Kia Sportage PHEV’s battery behavior. Here are a few notable observations based on real-world usage:

1. SOC vs. SOC BMS Discrepancy: It’s common to observe that the SOC BMS reading is slightly lower (e.g., around 5%) than the SOC displayed on the Kia Sportage’s instrument cluster. This suggests a buffer built into the battery management system. However, this difference may diminish at lower charge levels.

2. Battery Buffer and EV Range: The observed difference between SOC and SOC BMS, along with the point where the internal combustion engine (ICE) engages in PHEV models (around 15% SOC), indicates a total battery buffer of approximately 20% (5% + 15%). This buffer is designed to protect the battery and ensure longevity. The usable battery capacity for pure EV driving is therefore less than the total physical battery capacity advertised by Kia.

3. Cell Voltage Monitoring: Observing “Max Cell” and “Min Cell” voltages can provide insights into battery cell balance. Ideally, these values should be very close. Minor variations (e.g., 0.02V) are typically within acceptable limits and measurement tolerances. Significant voltage differences between cells could indicate potential battery health issues and warrant further investigation.
