Next‑Generation EV Battery Diagnostics

ClearWatt™ is FixAnyEV’s advanced diagnostic platform designed to deliver the most accurate, transparent and data‑rich EV battery analysis available today. Using manufacturer‑level tools, enhanced data modelling and real‑time thermal and charging behaviour analysis, ClearWatt™ provides a deeper understanding of battery health than standard SoH checks.

Ideal for buyers, sellers, dealerships, fleets and warranty providers who need reliable, independent and high‑resolution battery diagnostics.

What ClearWatt™ Diagnostics Measures

  • High‑accuracy State‑of‑Health (SoH) percentage
  • Battery degradation curve vs expected lifespan
  • Cell‑level voltage spread and internal balance mapping
  • Thermal system performance and cooling efficiency
  • Temperature behaviour during load, charging and regeneration
  • AC charging performance and charge‑rate stability
  • DC rapid‑charging acceptance and taper behaviour
  • On‑board charger (OBC) diagnostic review
  • HV contactor and relay behaviour
  • 12V system stability during HV activation
  • Full HV battery module diagnostic scan
  • ClearWatt™ digital diagnostic report with technician insights

Why ClearWatt™ Is Different

ClearWatt™ goes beyond a basic SoH reading. It analyses how the battery behaves under real‑world conditions, identifies early‑stage degradation patterns, and highlights charging or thermal anomalies that typical tools miss.

  • More accurate than app‑based or dashboard‑based readings
  • More detailed than standard dealer health checks
  • More transparent with clear, visualised data
  • More reliable for long‑term ownership decisions
