It explicitly says that if the car slows down the charge rate so that you would be in a lower price tier, you will still be charged the higher rate. Of course, chademo is limited to 50kW no matter what, so that won't affect Leaf drivers. Except, the chademo plug seems to always be paired with a low power CCS plug, so I wonder if that will encourage more drivers to use that charger even when they could use a CCS/CCS one.
I'm not positive, but I understood the charging scheme differently. I think you are tiered by the charge rate at the beginning of the session (or close to it.) The general idea is to presumably match your tier to the highest load during the session. This makes more than a little sense since the majority of the electricity costs are demand charges. It would have been fairer to use the peak load from the highest 15 minutes of a charging session since that is what the utility does but it may have been too much for their software .... or they are just screwing you .
If the price doesn't drop as the rate slows down, that will seriously screw Kona/Niro/Soul owners, as their peak rate is 77-78 kW, just above the 75kW cut but about as far below 150kW as it's possible to be. At Gallup, 75kW and below is $0.21/min, while 76 <= 150 kW is $0.58/min! As noted in the Niro topic by Tom Moloughney, the car charges at max rate until about 35% SoC after which it rapidly drops to 39kW, so anyone trying to get the lower rate would need to keep the battery above the 35% level, seriously limiting the useful range. This will have to be changed, through battery buffering or what have you.
