AC and seat heat battery drain

[tna9001]

Hello, All.

I was bored today so I thought I'd try and quantify how much energy the AC and heat seat use. According to my unscientific calculations*, the seat heat (on high drivers side only) and the AC set to 73 degrees (55 ambient temp) increase wh/mi by 23%. That sure seems like a lot of energy. Has anyone else done similar calculations?

*Test was 3 miles each way over the same stretch of road on the interstate at 60mph with the autopilot on. The start and stop points were fixed signs.

55 ambient and 'AC' set to 73 means you're using the heater. That's what's using the energy. The seat heater will be almost unnoticeable by itself.

It uses a lot of power. There's no sense in quoting "23 percent increase" without specifying what speed you are traveling at.
