We'll have to rethink this when someone starts DC Quick-charging, or direct-DC charging off Solar.DaveinOlyWA wrote:AMPK= AC miles per kwh which would be..."wall" power
I can't use these units because I don't have a direct view of DC (battery output) kWh. Assigning specific units to something inferred, approximated, or variable just makes for confusing results later.DMPK= DC miles or "battery" power.
Miles we can measure accurately.
"Wall" kWh we can measure accurately at the source.
Battery kWh, that's still Nissan's secret. Because of this, charger efficiency is also a debatable ratio.
If I had a favorite summary unit, it would be:
Wall Watt-hours per Mile.
Consumed Watt-hours per Mile?
And for now, A/C Wh per mile.
Because MPG is still our unfortunate unit for ICE, mi/kWh is a natural analog. It's still upside-down, though.
For instantaneous readout on the dash, my favorite values would be:
- Useable Wh remaining in the Battery.
- Instantaneous Watts Per Mile
- Average Watts per Mile for 1, 5, and 20 miles.
- Wh used from Battery since last charge.
- Instantaneous Watts
