Hi, I searched around a bit but didn't quite find an answer to my question. I've had my Gen III Prius IV for about 2 months. I've been getting great gas mileage on my 16 mile commute.. averaging 65MPG calculated over the first 2 tanks. My scheduled changed this week, so now my morning commute is in the pre-dawn hours. The last 4 miles of my commute, I barely need to use the ICE at all.. downhill.. low speed limits. I've noticed that in this stretch, that even though I'm really mostly gliding.. that SOC meter is dropping alarming fast.. like 4 bars in just a short period of time, when the ICE isn't being used at all. Since this is a residential neighborhood and it's very early.. I experimented this morning with turning the headlights off on that stretch and just using the running lights.. and sure enough.. the SOC plummet stopped. Is this normal? I would have thought the headlights would be run by the normal battery, not the traction battery.
