Electric and hybrid vehicles represent the fastest growing segment of the Australian automotive market — and as more EVs and hybrids appear on Melbourne roads, the demand for specialist high voltage diagnostics and servicing is growing rapidly. At National AutoTec, we are Melbourne's dedicated EV and hybrid specialist — providing comprehensive high voltage diagnostics, battery health reporting, depower and reinitialise procedures and pre-purchase inspections across all major EV and hybrid makes and models.

All high voltage work is carried out by EVT licensed technicians — ensuring every procedure meets Victorian safety requirements and manufacturer specifications.

High Voltage System Diagnostics Comprehensive diagnosis of EV and hybrid high voltage systems — identifying faults, degradation and performance issues across battery packs, inverters, motor controllers and associated HV components. Full written diagnostic reports provided.

Depower & Reinitialise Procedures Before any repair work involving EV or hybrid high voltage components, the HV system must be safely depowered and isolated. We carry out all depower and reinitialise procedures to manufacturer specifications — providing the safety clearance required before repairs commence and after completion.

HV Battery Health Reports A comprehensive battery health report assessing state of health, remaining capacity, cell balance and degradation across the full battery pack. Essential for pre-purchase inspections, insurance assessments and ongoing fleet management. Detailed written reports provided and accepted by major insurers.

Pre-Purchase EV & Hybrid Inspections Purchasing a used EV or hybrid without a professional inspection is a significant financial risk. Battery degradation, HV system faults and hidden electronic issues can cost thousands to rectify — and none of these are visible to the naked eye. Our pre-purchase inspection covers full HV system diagnostics, battery health report, full vehicle diagnostic scan, crash data check and written report — giving you complete confidence before you commit to a purchase.

Post-Accident HV System Inspection & Clearance After any collision involving an EV or hybrid, the HV system must be professionally inspected and cleared before repairs commence and before the vehicle returns to the road. We provide formal HV system inspection reports accepted by all major insurers — an increasingly important requirement as EVs enter the smash repair ecosystem.

Thermal Management System Reset EV and hybrid thermal management systems require resetting after battery or cooling system repairs — ensuring correct temperature regulation and battery performance after any HV related work.

EV Charging System Diagnosis & Repair On-board charger diagnosis and repair, charging port diagnosis and fault rectification — covering all EV charging system components across major EV makes and models.

EV Vehicle Testing Victorian EV vehicle testing carried out by our EVT licensed technician — providing formal EV roadworthiness testing and certification.
