Скачать или смотреть 1st V3 Supercharge with 90kWh replacement battery in our 2012 Signature Edition P85 Tesla Model S

We went to the Thornton Supercharger which is V3 and and should deliver upto 250 kW. Driving from Cheyenne, Wyoming in 70°+ weather, and destination programmed in to pre-condition we were hoping for faster charging than what we get in Cheyenne, which is V2 (150 kW maximum).

We arrived with 20 percent SOC (State Of Charge) and were underwhelmed by the result, 115 kW. We charged for 12 minutes and were at 52 percent SOC, which actually is much better than our original battery. We'll see if Tesla can do anything to improve this, but even if they can't, it maintained greater than 100 kW during the entire charging session. Our old battery would have had a maximum rate of 88kW and during most of the charging session would be 30 - 45 kW.

The only source of our disappointment was the expectation created by what the representatives from Tesla stated about the upgrade battery performance. They need to either be more realistic or figure why our battery is not operating in the manner they said it would (V3). Had they told us that it would perform like this (V2), we still would have picked the upgrade instead of a remanufactured replacement, but would not have any sense of disappointment about it. I hope sharing this information helps others who are considering options if their Tesla High Voltage battery is out of warranty and needs replacement.


UPDATE: May 3, 2021 - I got a call from one of the Service Technicians at the Superior Tesla Service Center. Aside from an apology for the prior miscommunications, he explained much, and per my request followed up with an email so I would have a record of our discussion. Here are excerpts from the email I received, which accurately reflects what we discussed as it pertains to the HV battery:

"Just wanted to follow up and try and provide a summary of what we discussed over the phone regarding the new HV battery we recently installed in your vehicle. I do apologize again for the miscommunication about the charging rates. Unfortunately, even though the battery itself is capable of charging at a higher rate, the other charging components installed in the vehicle are not capable of charging higher than what you are currently seeing under ideal conditions. This is something we definitely should have communicated better with you and I am sorry for that.

I asked one of the high voltage battery engineers about the change in voltage from 400 to 350 and found out the internal architecture of this battery is different than what your vehicle originally had installed. This new architecture actually allows for improved performance than your original battery was capable of at a slightly reduced voltage. This is due to some different battery cell chemistry as well as improvements to other hardware within the battery. These changes create a more consistent voltage during acceleration (less voltage drop) and improved and more consistent current flow to the drive unit increasing the performance of the vehicle.

The last thing I would like to mention is that the battery you have is completely brand new, no remanufactured or used parts are present, even the housing is a completely new piece. I hope this helps explain a little more about your battery. If you do have any further questions I can answer, please feel free to reach out."

I appreciate the communication and clarifications. We would have done the same repair with this information, but our expectations would have been different. I am satisfied with this response from Tesla.
