Sydney's specialist electric vehicle pre-purchase inspection service. Our EV-trained mechanics travel to any seller's address across Greater Sydney — battery state of health testing, charge-cycle history, range estimation, charging port integrity, electric motor assessment and full OBD scanning for all EV brands. Same-day written report. From $299.
Electric vehicles require specialist equipment and training that most general mechanics simply don't have.
The battery pack represents 30–50% of an EV's total value and is the single most important component to assess. Standard OBD scanners cannot read battery state of health — specialist diagnostic equipment that directly accesses the Battery Management System (BMS) is required.
Electric motors, inverters, high-voltage cables and power electronics require specific diagnostic knowledge and safety protocols. Assessing motor performance, efficiency faults and inverter health requires EV-specialist training beyond standard automotive qualifications.
Charging port condition, connector pin wear, on-board charger performance and charge acceptance rate testing cannot be assessed by visual inspection alone — they require active diagnostic testing with specialist EV equipment.
Battery State of Health (SoH) is a measurement of an EV battery's current capacity as a percentage of its original factory capacity. A new EV battery starts at 100% SoH. As the battery ages and accumulates charge cycles, its capacity gradually decreases — this is called degradation.
SoH directly determines how far you can drive on a full charge. A Tesla Model 3 Standard Range with a rated range of 491 km (WLTP) at 100% SoH delivers approximately:
90%+ SoH is excellent — minimal degradation. 85–90% is good but should be reflected in price. Below 85% means significant range reduction — negotiate accordingly. Below 80% SoH means battery replacement ($10,000–$25,000) may be approaching and requires very careful consideration.
BYD Blade Batteries and some Tesla batteries use LFP (lithium iron phosphate) chemistry, which degrades differently to the NMC chemistry used by BMW, Hyundai, Kia and others. LFP batteries typically show lower percentage degradation but have different SoH measurement characteristics — our specialist equipment handles both accurately.
