FixAnyHybrid London – 07448 457247

Independent certification of your EV’s high‑voltage battery and HV system. Mobile testing for buyers, sellers, fleets and private owners.

Independent EV Battery & HV System Certification

Your EV’s high‑voltage system includes far more than the battery pack. Our EV Battery & HV System Certification provides a complete, independent assessment of the battery, HV contactors, cooling circuits, sensors, charging behaviour and overall system integrity.

This certification is ideal for pre‑purchase inspections, selling your EV, warranty evidence, fleet safety audits and insurance documentation.

What the HV System Certification Includes

  • State‑of‑Health (SoH) percentage
  • Battery degradation vs expected lifespan
  • Cell‑level voltage spread and internal balance
  • Thermal system performance and cooling efficiency
  • Temperature stability during charging and load
  • AC charging performance and charge‑rate behaviour
  • DC rapid‑charging acceptance and stability
  • On‑board charger (OBC) functionality
  • HV contactor and relay behaviour
  • 12V system stability during HV activation
  • Diagnostic scan of all HV battery modules
  • Independent digital HV system certificate with technician notes

Who This Certification Is Designed For

  • Private buyers verifying EV condition before purchase
  • Sellers wanting proof of HV system health
  • Dealers needing independent verification
  • Fleet managers conducting safety and reliability audits
  • Lease return inspections
  • Insurance and warranty documentation

Why HV System Certification Matters

The HV system includes contactors, sensors, cooling circuits, relays and control modules — any of which can affect safety and performance. This certificate confirms the entire HV system is functioning correctly, stable under load and free from hidden faults.
