Why not a fossil fuel heater for the Leaf or BEV's?

Mon Oct 24, 2011 10:33 pm

OK, so we know that BEV range gets hammered during cold days, particularly in climates that experience cold winters. We know that there are heaters that consume fossil fuels, but do so in a highly efficient manner- more efficiently than an internal combustion engine.

Why not put a fossil fuel powered heater (propane? gasoline?) in BEV vehicles like the Leaf? By burning a small amount of a readily available fuel for heat, one could significantly increase a BEV's range during the winter months by allowing the battery to drive the car instead of being wasted by heating the cabin. It would suck having to burn a fossil fuel at all, but at least it would preserve the BEV's winter range and make the car more functional while also burning that fossil fuel in a highly efficient manner- certainly more efficiently than an internal combustion engine would.

The worst heaters in the world are the petrol burning Janitrol heaters in airplanes.

No thanks.

I am not talking about the heater in a 1954 Apache! I am talking about a modern, highly efficient heater that could greatly increase the cold weather range of a BEV like a Leaf in cold, winter seasons.

I think last winter Nissan said the Leaf would do about 50 miles slogging thru snow, heater blasting etc.

I still think an electrically heated motorcycle vest consumes a lot less power and will keep you very warm, plus it heats up instantly.

Webasto makes a line of diesel fueled auxiliary heaters, they tie into the antifreeze coolant loop of an ICE vehicle, perhaps it can be adapted to a Leaf.. popular in cold countries to heat up diesels.

In Norway it is quite common to install Webasto and similar heaters in electric cars for winter use.
My hope was that the Leaf with is preheating would not need this. I live in an area where temps during winter is rarely below 20F, and my commute is not very long.

You'd want something that safe, burns clean and is ideally easy to get anywhere. Alcohol is a great choice for this, IMHO. You can pick up a bottle of 70% Isopropyl Alcohol at any pharmacy or supermarket for dirt cheap and 99% concentrations are like $10 a liter or so. (In a pinch maybe you can stop at a liquor store and get some bottom-shelf vodka... seriously officer, it's for my car!) Butane is my #2 choice since you can pick up refill canisters of it at any hardware store.

Just gotta figure out where to install it. Something that installs like a child seat would be pretty nice if you can figure out the venting. Maybe you can fit something into the space between the rear wheels to heat water and pipe it up to the existing heating system?

The 1997-1999 Honda EV Plus had a fossil fuel heater when deployed in colder climates. Living on the San Francisco peninsula however the one I had did not.

Because then you go back to having to fill your car with a gas (ethanol)?

If I was in a very cold climate I would consider an aftermarket kit that replaced the electric coil with a small propane burner.
Small disposable/recyclable canister would be fine.
Might be a viable product when 2M Leafs are on the road.
1 bar lost at 21,451 miles, 16 months.
2 bar lost at 35,339 miles, 25 months.
LEAF traded at 45,400 miles for a RAV4-EV
