As many were aware, the previous software version (2022.47) severely miscalculated total energy to the point that it was reporting total energy usage as roughly half of what it should be. This bug seems to be fixed in 2023.2.3, which allows one to calculate how much the truck is losing to vampire drain / idle energy usage.
I reset the trip meter right after updating. After 48-hours checked the numbers:
Total Distance: 65.9 mi
Duration: 3 hr 7 min
Efficiency: 1.89 mi/kWh
Total Energy: 37.9 kWh
If I'm reading this correctly, during the ~3hrs of driving, the truck used 34.9 kWh of energy. That leaves 3 kWh of total energy usage unaccounted for during the other 45 hrs of this measurement, which equals 1.6kWh of vampire drain per every idle 24 hours.
These numbers are with gear guard enabled everywhere. High of 61F and low of 39F during this time period. I didn't charge the truck during this measurement.
Overall, these numbers are in line with my anecdotal observation of 1% daily vampire drain and similar to what others have reported. It's not that big of a deal to me or enough for me to disable gear guard, but still I hope Rivian is able to further optimize and reduce idle energy usage.
