IONIQ 5 Companion

New in 2.0: more on CarPlay than ever — new Power, Compass & charging chips. A private drive & charge history via iCloud, for IONIQ 5, 5 N, 6, 9 & Kia EV6.

IONIQ 5 Companion is an independent diagnostic tool for the Hyundai IONIQ 5 and IONIQ 5 N, now with full support for the Kia EV6, IONIQ 6, and IONIQ 9. Plug in an ELM327-compatible BLE OBD-II adapter and it reads battery, charging, tire, and ECU data directly from your car. A built-in History records every drive and charge and syncs across your devices via iCloud.

CARPLAY

• Two rows of live chips on the Driving tab — charge, power, tires, climate, and more
• New chips: Power (draw and regen on one dial), Compass (optionally replacing the odometer), AC Draw (live volts, amps, kW), and Cell Voltage Δ (a per-cell heatmap)
• Dynamic Charging and EVSE tabs during charging, with a session timer and the charger's reported capabilities

HISTORY & ICLOUD

• New History tab records every drive and charge, with live State-of-Charge charts plus distance, energy, peak-power, and battery-temperature ranges
• 50+ signals logged over time on charts you can pinch, pan, and scrub — voltages, temperatures, motor RPM, isolation resistance, charging power, and more
• Optional iCloud sync keeps your history in step across iPhone, iPad, and Mac
• Attach a photo and share a clean report card with one tap

LIVE DASHBOARD

• State of charge, available energy, voltage, current
• New: Regeneration gauge, Gear indicator (P, R, N, D), Isolation Resistance chip, and Polling Headroom indicator
• Cell min/max temperature and per-cell voltages as a color-coded heatmap with an explainer
• Tire pressures and temperatures, motor RPM, ignition state, battery heater status
• 12V auxiliary battery — charge, voltage, current, temperature, plus DC-DC converter telemetry
• Outside and cabin temperature, relative humidity, headlight and brake-light indicators

CHARGING TELEMETRY

• Live AC and DC charging detection
• Session detail plots Charging Power, Pack Voltage, battery and ambient temperature, banded by AC, DC, and preconditioning
• DC fast charging: a new EVSE Current chart compares requested vs. delivered current, plus an EV Supply Equipment card with the station's max power, voltage, and current (J1772 + CCS)
• Live "Time to 70°F / 21°C" battery ETA for optimal DC fast charging

CONNECTION & SETTINGS

• Connect, disconnect, and toggle Auto-Connect to share one adapter between apps
• Keep Screen Awake while the app is in the foreground
• Choose Power units (kW, HP, PS) and Efficiency units (mi/kWh, km/kWh, kWh/100km, Wh/mi)

ADVANCED TOOLS

• J1979 OBD-II Scanner — standard mode 01-09 read-out for adapter compatibility
• ECU Finder maps every ECU; DID Range Scan probes one across an address range; Curated DID List scans all 65535 addresses; an A/B/C test hunts new signals — with result sharing
