That aside, the graph was originally produced to expose the fallacy of Audi's claims that ~ 150 kW charging with a late taper is superior to the Tesla network. Look at the kWh added vs time
the "no knowledge necessary" approach that Audi is using
What are you talking about ?
Whenever we have a newbie come in here, we have to explain to them that the charge rate will taper, that it may or may not be worth QCing beyond 80%, depending on the price/kWh or minute, blah blah blah.
This is on top of telling newbies that for longevity it's best if they keep the SoC between X and Y%, (with the inevitable extended discussion about what the values of X and Y should be), that you probably don't want to go below Z% on a regular basis, that if you charge to 100% you shouldn't leave it there for any length of time especially if the temp is over T degrees and it's best to avoid using it if you don't have to, unless you need to do it to balance the cells, yada, yada, yada. It can be intimidating, and whether it is or not, that level of knowledge shouldn't be necessary for members of the general public who just want to use the car, not take an exam in battery care and maintenance. Early adopters are willing and usually interested enough to learn all that, but the mass market isn't.
Compare that to an ICE: fill it up, run it down as much as you want and then repeat; that's it. Audi's approach is "you will gain about X kWh/miles of range every minute of charge regardless of your starting and ending SoC; feel free to use the entire SoC range". This is essentially the same as the liquid-fueled ICEs everyone's used to. Which is simpler? Which is preferable?
People shouldn't need to know a secret handshake just to use the car to its max. capability and have their battery last a reasonable length of time.
