To promote healthy battery life, we are told ‘by some’ to keep the state of charge between 20% to 80% with our 75 kWh batteries.
Now when the 60 kWh Model 3 comes out, it will basically be a 75 kWh battery software locked to only utilize 60 kWh.
Question: Will the 60 kWh version use the upper state of charge of the 75 kWh battery where all of the small batteries are charged to 4.2v apiece? If so, then to promote battery health would you be asked to keep the state of charge between 0% and 75%?
0% voltage equaling the voltage of a 75 kWh battery at 20% and 75% equaling the voltage of the 75 kWh battery at 80%. It’s still the same battery regardless of how much you are allowed to use.
If the 60 kWh battery utilized the median SoC of the 75 kWh battery, then it would seem that it would be harder for people to damage their battery if they were to charge it to 100% on trips because 100% on the 60 kWh version would be about 90% SoC of the 75 kWh battery that it really is. And draining the software locked 60 kWh battery to 0% is still leaving 10% charge in the battery (which is really a 75 kWh battery). Battery health could be optimized by using 10% to 90% SoC if you have the 60 kWh version.
Now I didn’t want to nitpick the exact numbers or argue the 20-80 or 30-70 SoC. I just wanted to get the main idea across.
Wonder which way they will go when they software lock the 60 kWh range available of the 75 kWh battery.
I’m now sick and tired of typing kWh over and over. Argh!!!
