I was thinking about the fact that initially we were given the ability to set the charging current and then the charging power.
According to the specification sheet downloadable from Stark’s site in its support section, the voltage range for an MX 1.0 is 250 - 420 V.
This means that if you charge at 3 A when the battery is at low State of Charge, the charging power can be for example 3 A * 270 V = 810 W, while when the SoC is high it can be like 3 A * 400 V = 1,200 W, which is quite a difference. The charging speed should therefore increase as the SoC increases: at the beginning it takes more time to gain 1%.
If you set a constant power like 1kW, on the other hand, the current should theoretically become lower and lower as the charge and voltage increase and the charging speed should be constant: if it takes 2 minutes 14 seconds to gain 1% at 23%, it will still take the same time at 74%.
So I think switching to the power setting has been a good move because now it’s easier to predict the charging time.
