Another question. If the battery proves to be indeed degrading faster than normal and we bring it in for warranty service, does Porsche actually replace the battery or just use the software to release the reserved capacity?
Another quandary:
If using the OBD Energy Available data, the Original SoH at deliver actually would be 85.2 kWh!
(47.9kWh/65.5%)/85.85%
So did Porsche actually made more tan 83.7 kWh usable?
@ciaranob. Thanks for the feedback. My car is the 2021 RWD. It was delivered September 2021. How can I find out when it was built?
I would like some opinions on the following points:
1. I wonder if this significant loss of capacity was due to me charging at the 150kW EA Stations exclusively...
SoH indicated by OBD is confusing. Can anyone enlighten me?
SoH as displayed on OBD 85.85%
SoC displayed 65.5%
Battery Energy (Available) 47.9 kWh
Calculations:
SoH from: Energy and SoC Data
100% SoH = 47.9kWh/65.5% = 73.13 kWh
But Porsche claims 100% SoH at delivery is 83.7 kWh
Battery...
@ciaranob , Got the OBDII. Great recommendation. Works like a charm with the iOS. But This is what I got. Can't make sense out of it. What is the SOH 85.85% here? Porsche state the usable capacity is 83.7%. What is this a percentage of? And what is the difference between SoCHR and SoC Display?
@4thPcar , as I understand it, preheating the car helps to charge the car faster. But since you are charging at home, I don't really see the benefit. On the other hand, it is the heat generated in the battery from the high speed DC charging that is detrimental to the battery health. So as far as...
BTW, my dealer just told me that on average, Taycan loses 10% of the SOH in the first year of average annual driven mileage (12000 miles?). Unfortunately, we don't know if the initial SOH of the 93.4Wh battery was indeed 3.7 as Porsche reports. (There are discussion that it is actually more.)...
Mine: 2021 Taycan RWD, after 120000 milds in moderate weather has 240 on Normal Drive and 153 on Range Drive. BTW, I have been using the EA 150KW charger exclusively.
Thanks!
I don't have an OBDII unit. I have been estimating my %SOH by relying on reading on DC Charger. Calculate it with: #kWh put in/ %Usable Battery capacity replenished
Does that work?
The 3-year free DC charging we get here in there U.S. is at rates of 150kwh-350kwh. Where as I do not know what the rate is at the DC charging mentioned here in the following quote of estimate from the Idaho National Lab.
"The INL tested two pairs of Nissan Leaf EVs from the 2012 model year that...
Since we all get 3 years of free DC charging with our purchase, this would be a worthwhile analysis. According to one report for the Nissan Leaf, the difference is 3% more loss of SOH after 50000 miles. What do you think it is for the Taycan?
