Battery Health & Diagnostics
Monitor your battery's State of Health (SOH) over time, track degradation rates, project future capacity, and keep an eye on tire pressure — all from continuous data collection.
Battery State of Health
The battery health page provides a comprehensive view of your EV battery's condition and projected lifespan.
Current SOH Display
A large, prominent display shows the current battery SOH percentage with a color-coded health status indicator. The color zones provide an immediate visual assessment:
80-100%
Excellent
50-80%
Good
20-50%
Low
0-20%
Critical
Degradation Statistics
Below the SOH display, key degradation metrics are shown:
SOH Projections
A projection table estimates future SOH values based on the observed degradation rate:
| Timeframe | Projected SOH |
|---|---|
| 1 Year | ~97% |
| 2 Years | ~94% |
| 3 Years | ~91% |
| 5 Years | ~85% |
SOH Trend Chart
A historical line chart plots every recorded SOH value over time. The chart background uses the same four color zones (green/light-green/orange/red) to give immediate visual context. Data points are connected chronologically, and the trend line reveals the gradual degradation pattern. Hovering/tapping a data point shows the exact SOH percentage and date.
Tire Pressure Monitoring
The tire pressure page provides a visual overview of all four tires' warning status, combining a car diagram with historical trend charts.
Visual Car Diagram
An SVG top-down view of the vehicle with each tire position color-coded: green for normal pressure, red for a pressure warning. A status chip at the top provides an overall assessment (all OK or warning detected).
Example: 3 tires OK, rear-right warning
Pressure History Charts
Below the car diagram, four individual stepped-line charts show the warning state history for each tire (Front Left, Front Right, Rear Left, Rear Right) over time. A time range filter (7 days, 30 days, all data) controls the chart period. Since the Kia API only provides warning flags (0 or 1) rather than actual PSI values, the charts show binary OK/Warning states.
Battery Capacity Analysis
The capacity analysis page provides deeper insights into the battery's usable capacity over time, tracking how the effective kWh capacity changes as the battery ages. This complements the SOH percentage with absolute energy values.
