I'm getting extremely high consumption numbers over the first few minutes of my drive. It usually regulates if I get on the highway, but I live in NYC so the highway isn't always an option.
By high energy, I mean 1000+ Wh/mi to start. That slowly (sometimes very slowly) creeps down to 500 Wh/mi, and eventually regulates to +/- 200 Wh/mi once I'm going 50mph or more. I am very aware of the factors that affect energy, and I'm not abusing any of the known culprits:
- I'm often going <30 mph, and rarely drive over 70 on the highways around NYC.
- A/C fan is usually on 2. I still get high readings when A/C is off (I've tested it all)
- I get these readings regardless of whether or not I pre-condition the cabin temp.
- I'm not accelerating in an aggressive way
- My tire pressure is perfect, approximately 48psi as recommended
I've read every forum and watched every video I could find (within reason), and I haven't seen anyone with this particular problem. A consumption surge of 1400 Wh/mi when I'm driving 20 mph with no A/C just isn't normal.
I have a two year old in the car, and I need to know that my energy readings are reliable and that my battery isn't malfunctioning in a potentially dangerous way.
No snarky comments, please. I understand the basic science of the car and the physics of driving.
