You keep making unit mistakes. Charging rate is measured in kW, a unit of power. There's no /h, no /hour, no per hour.That calculates to 20 kW/hour (31 kW in 1.5 hours). Then there is time remaining 4 hours. Lastly, what does the 99 indicate? I understand it's supposed to be the rate, but that does not make sense.
For "31 kW in 1.5 hour", are you talking about 31 kWh? Energy is measured in kWh.
If you charge at 50 kW * 1 hour --> 50 kWh came out of the "wall". Multiply units and values.
50 kW * 2 hours --> 100 kWh
100 kWh / 2h --> 50 kW as h divided by h cancels out.
31 kWh / 1.5 hours --> ~20.67 kW
20.67 kW * 1.5 hours --> 31.005 kWh
Notice the chargers are labeled in kW. When you charge, watch the screens. You'll see that the power level is correctly in kW and energy dispensed is correctly in kWh.
Skip to 7:00 of the video at https://insideevs.com/news/495913/nissan-leaf-dc-fast-charging-curve/. Notice that charging power is in the middle (kW). Energy dispensed is in kWh (upper right).
Watch the video at https://electricrevs.com/2018/07/17...hargepoint-express-250-charge-at-up-to-55-kw/. The software on that unit gives a bit more info. Yes, I know it's a Bolt.
