The health test is probably a bit too positive.I had the same thought, so I ran the battery health test in service mode yesterday. The results showed battery health at 92%, but the estimated range is still 227 miles. That math doesn’t add up, right (I started at 253, so 92% should be 232)?
The delivered energy is dependant on the power during the discharge. Lower power makes the battery deliver more energy.
The healt test use the AC/climate (?) to discharge the battery?
Anyway it is a slower discharge than normal driving (from where the BMS calculated energy comes) so the result would by principle exaggerate the real capacity in that test.
