So finally I had a chance to run down my battery as much as possible, and I was at 12% with 0 range displayed when I plugged in. This morning after a full charge my meter is saying I used 9.15kWh. However we do need to take into account that probably 1-2% is lost during the charging process.I've seen as high as 8.3kWh (measured by the Chargepoint charger I normally use). Of course, that doesn't account for any losses in the Niro's onboard charger. For example, if the Niro's charger is 98% efficient the actual energy delivered to the battery pack would be ~8.1kWh.
