Charging constant - degradation threshold / EPA miles
Drmi - displayed rated miles. These are 4.5% smaller in energy than charging constant
I don’t talk about energy constant.
In the past for simplicity I have referred to charging constant and discharge constant with discharge constant representing energy in each displayed rated mile which is 4.5% less than the charging constant.
Charging constant is used in a lot of places to display information. Charge events (incorrect), energy screen (incorrect), rated line (5Wh/mi above charging constant).
Discharge constant is never explicitly used but is the energy in each displayed rated mile.
No. This is what it says on the screen but it is wrong.
Use the 4.5% less value for that.
Just remember for the displayed range it only displays 95.5% of your energy in your pack when at 100%. Then it all makes sense.
I can’t explain why everything is displayed incorrectly. Just the way Tesla does it.
If you want to know energy loss use the Charge stats in the app, and compare the number on the screen multiplied by 95.5% to the app value.
The losses will be about 10% or a bit higher for slowing charging setups (I have never experimented with those to see how accurate the metering on the charge stats is - in theory it can be quite accurate by integrating voltage*current but I don’t know what sig figs they have on the current especially at lower currents).
All very straightforward in the end.
