Specialist High‑Voltage System Inspections for EVs

Your EV’s high‑voltage system is the backbone of its performance, safety and reliability. Our Professional EV High‑Voltage System Inspection provides a detailed, independent assessment of the complete HV architecture — not just the battery.

Ideal for buyers, sellers, dealerships, fleets and warranty providers who need confidence that the entire HV system is operating safely and correctly.

What Our HV System Inspection Covers

  • High‑voltage battery State‑of‑Health (SoH) percentage
  • Battery degradation vs expected lifespan
  • Cell‑level voltage spread and internal balance
  • HV contactor and relay behaviour
  • Insulation and isolation fault checks (where supported)
  • Thermal system performance and cooling efficiency
  • Temperature behaviour under load and charging
  • AC charging performance and charge‑rate stability
  • DC rapid‑charging acceptance and taper behaviour
  • On‑board charger (OBC) diagnostic review
  • 12V system stability during HV activation
  • Full diagnostic scan of HV battery and HV control modules
  • Professional digital HV inspection report with technician notes

Why a Professional HV Inspection Matters

The HV system includes more than just the battery — contactors, inverters, chargers, cooling circuits and safety controls all play a critical role. Faults in any of these areas can cause safety issues, breakdowns or expensive repairs.

  • Identifies hidden HV faults before they become failures
  • Supports safe operation and long‑term reliability
  • Provides evidence for warranty and insurance decisions
  • Protects buyers and fleets from unexpected repair costs

Who This Service Is For

  • Private buyers checking an EV before purchase
  • Sellers wanting proof of HV system health
  • Dealerships and trade buyers verifying stock
  • Fleet operators managing EV reliability and safety
  • Lease return inspections and end‑of‑contract checks
  • Warranty and insurance assessments
