Hi Robert, I have a similar complaint. How did it all play out for you? Do you have a link to the most up-to-date ATO advice you used? I bought a smart plug for my Outlander PHEV to try and claim actual home electricity costs. I dont need a dedicated charger with speeds that exceed what the car is capable of charging at. Plus trying to avoid spending in excess of $1000 for a changer I don't actually need.
I am happy with the 'granny charger' speeds at 8A and willing to do a stat dec re the actual costs to submit my electricity claims. I have complained to MAXXIA about them rejecting my submissions too. I am using a lot more electricity than petrol with my PHEV.
Thank you
