I’m charging at this bank now, and with two other vehicles at the other end of the row. I got 50kW at first but it’s dropped to mid thirties. I was at 60% when I started so I’m not sure if that has anything to do with it, but from my experience this doesn’t seem to be V3 speeds. All units are supposed to get 250kW, correct?
No. Read up a little bit on how batteries charge. As they get 'fuller', they ramp down the amount so as not to cause damage. There are plots of this on the forum (almost since the beginning) and, I'm sure, if you note the charging rate of your car, it will fall close to the plot. Over time a good way to tell if battery may have a problem.
Hint for charging - to get the most from a charger - as you get within 10 miles, make that charger your destination. The car will pre-condition the battery to receive maximum amount of charge (for it's current condition), thus you start of strong when you plug in.
