Is the State of Health of an EV battery included in an NRMA pre-purchase inspection report?
When the NRMA does a pre-purchase inspection of a used car, the NRMA sites says "We plug in a diagnostic scan tool to detect any fault codes on all car types including electric and hybrid." Does the report on the vehicle include reading out the 'State of Health' (SOH) of the car's traction battery? IE Does the report tell a prospective buyer that 'The battery retains x% of its originally rated capacity'. This would be useful information to give confidence to a prospective buyer and would also help the seller to demonstrate that the battery remains in good condition. I think this would be the single most useful thing to know about used EV.

In the absence of a response from NRMA, if the current owner keeps a log of charging, energy use and distance travelled etc (we do), then it is possible to determine, reasonably accurately, what the battery SOH is.
I've yet to find an OBD2 scanner that is guaranteed to work with my vehicle, but a decent quality unit that works with EVs may be able to give SOH information too.

Hello @PeterCa , apologies for the delay here. We've checked in with our vehicle inspection partner and can confirm that their process is as follows:
As the 2nd hand EV market matures, the industry is working to improve and respond with what data us available and accessible to give a more precise reading on the battery.
