@ventrap, Be aware that the km/hr (and mi/hr) reading on the charging screen is an average over the whole charging session, while the kW displayed is instantaneous. The km/hr display will lag on the actual slowdown, not showing you how slow the vehicle is actually charging at that specific time. The km/hr displayed also includes the several seconds that it takes to actually start charging. This means the km/hr displayed lags the actual charging speed as it both ramps up at the beginning and down as the charging speed starts tapering off.
@Dre78, The Urban Supercharger sites can provide a constant 72 kW at any time, assuming the car is able to accept that full power. If you're seeing these slow (30 kW) supercharging sessions, but don't have your battery at 70% full or higher, it's likely that your battery is a little cold. To get the full charging speed, you need to drive for something like an hour. If you see any "regen dots" below the speedometer, your battery is likely too cold to accept the full charging speed. Try charging at the end of your driving for the day when the battery is warmer than it would be after parking in the cold overnight. If you're charging in the morning after parking in the cold, try to drive an hour before attempt to supercharge. You'll eventually get the battery charged, but by trying to get the battery warmed up a little by driving the car, you should get higher kW charging speeds, particularly at Urban Superchargers where you don't need to worry about pairing of the charging stalls.
