Battery Capacity Test Results

Keep an eye on this thread.
I will post there as soon as I learn anything new.

 

I had Honda of Pasadena pull the full EV powertrain data as well as individual cell voltages. After 18 months and 15,000 miles the capacity is 49.9Ah. That’s about 9% below the 55Ah capacity for a new battery. We did not receive this information from the selling dealer at the time of purchase, so I do not have that data to compare. I have contacted them to see if the PDI was performed and if they have that data
available.

SOC at the time of the test was 79%. Usable capacity for as 82% for Line A and 83% for Line B.

Line A Minimum cell voltage was 3884.2mV
Line A Maximum cell voltage was 3904.0mV

Line B Minimum was 3888.4 mV
Line B Maximum was 3905.2 mV

This was during the A01 service. They charged a $142 diagnostic fee. The A01 charge was discounted $5, to $60 and they took 10% off the entire bill. Total was $186.50. I don’t plan on asking for this data again unless the mileage goes south. I still seem to be getting the same range as when new.

They also printed out 12 pages of information, at my request, that provides a detailed explanation of each fuse, since I was unable to decipher about half of the acronyms used in the manual.

Finally, they fussed with the A-pillar trim that has separated at the dash. It’s a half buttocks job and they said it’s a common problem that has no solution. I don’t know if enough of us can pitch a fit to get a recall issued. What am I thinking, Honda doesn’t listen to us.
