I just uncovered the traction battery for the first time. (Cover is held on by Velcro!) Anyhow, there seems to be a lot of space around the battery where I could add some sort of heating pads. On those -40° days it would be nice to start out with a warm battery and engine.
I also just threw a space heater in the trunk that I will be using to warm the cabin before driving. Some of my drives are very short.
I'd like to add more engine heating/insulation. One idea I have is to install a tank type heater, but with a pump. Normally the problem I have with tank type heaters is that it's hard to install them just right so that they draw water from down low and perculate up high. And usually when you do them right then the flow is backwards from what the engine pumps while running, so they're useless if you're trying to use them with the engine on. But with a pump that problem would be solved. Plus, if I get enough heat, I could turn on the car and heat the interior at the same time. If there's enough heat coming from the tank heater then the engine should not turn on, or not stay on for very long, while I defrost the windshield and heat the interior. I'm not sure if it can be done, but since the engine apparently already uses electric pumps, I wonder how hard it would be to wire it up to turn on the pump that goes to the heater core and put a tank type heater inline with that.
