Last night, I conducted a battery health test on my 3-month-old 2023 Tesla Model Y Long Range, which has 8,500 miles on it.
I connected the vehicle to a 10 kW Level 2 public charger, accessed the service mode, and initiated the test.
The test says it requires at least a 6 kW supply.
Although I was initially concerned about being able to lock the car, I found that the Tesla app allowed me to do so.
I locked the vehicle, left it overnight and monitored the testing process remotely.
Initially, the car ran its motor and fans to deplete and warm up the high-voltage battery.
It took less than 2 hours to reduce the state of charge from 27%.
Once the SoC dropped to 8%, the car went into sleep mode and reawakened after roughly an hour.
After charging to full, the test indicated a 3% battery degradation, aligning with the estimated 100% range.
Declared rated range for such model and configuration is 330 miles.
