EV Inspection: Special Considerations
Electric vehicles represent the fastest-growing segment of the Indian automotive market, and PDI for EVs requires a significantly different approach than for internal combustion engine vehicles. Here's what makes EV inspections unique.
Battery State of Health (SOH)
The battery pack is the most critical and expensive component of any EV. During PDI, we check the battery's State of Health — its actual capacity relative to its original design capacity.
A new EV should have an SOH of 98–100%. Anything significantly below this at delivery indicates either a defective battery or a vehicle that has been extensively tested or driven before delivery.
Charging Port Verification
All charging ports must be tested — both AC (home charging) and DC fast charging ports.
This is a frequent failure point in new EVs, and a non-functional charging port discovered after delivery becomes a complex warranty claim. Testing at delivery takes minutes; fixing it later can take weeks.
Thermal Management System
EV batteries require active thermal management to maintain optimal performance and longevity. The cooling system for the battery pack must be checked for leaks and proper function during PDI.
Regenerative Braking
Unlike conventional brakes, EV regenerative braking systems require specific testing. The various regen modes should be tested during the PDI test drive to confirm they engage, hold correctly, and provide the expected deceleration without noise or judder.
Software Version Verification
Modern EVs are software-defined vehicles. At delivery, the vehicle's software should be on the latest manufacturer-released version.
Older software versions may have known bugs or missing features. Confirm the software version and check for any pending over-the-air updates.
Drive Unit Inspection
The electric motor and reduction gear assembly should be tested for unusual noises — whining, clicking, or grinding.
These are uncommon in new units but have been found during PDI inspections of some popular EV models.
Standard Checks Still Apply
Everything on a conventional PDI checklist still applies to EVs — panel gaps, paint quality, tyre dates, interior quality, glass condition, and documentation verification.
The EV-specific checks add to, rather than replace, the standard inspection protocol.
Why EV PDI Is More Critical
The cost of EV components — particularly the battery pack — is significantly higher than equivalent ICE components.
An undetected battery issue or charging defect can result in repair costs that dwarf the price of the inspection. For EV buyers especially, a professional PDI is not a luxury but a necessity.
