First, keep the batteries warm. Plan on putting the batteries in fully
closed well-insulated boxes, with about 1" of styrafoam insulation on
all sides. Include some kind of heating mat; with this insulation, it
only takes about 25 watts per battery.
For heating the interior, there are at least three options: electric
water heater, electric air heater, or fuel-fired heater.
An electric water heater is a small coffee-can sized tank with a heating
element, pump, and hoses. It produces hot water that is pumped through
your vehicle's existing heater core, to provide heat exactly the same as
for the stock vehicle. This method has the slowest warm-up time, but is
the easiest to add because you don't have to take the dash apart or
replace the heater core.
An electric air heater is usually one or two ceramic heating elements,
installed in place of the vehicle's existing heater core. It's the
cheapest approach and provides instant heat. But depending on the
vehicle, it can be very difficult to install.
A fuel-fired heater uses gasoline, diesel, or some other fuel. It is
essentially a miniature version of a home furnace, built to go in a car
or truck. Several companies offer these, intended for trucks or other
commercial vehicles. They work fast and make lots of heat, and have no
effect on range. But they can be noisy, smelly, somewhat difficult to
install, and you have to buy fuel.
Note: Cars treat heat as "free" and so have zero insulation. You'd never
consider trying to heat your house with no insulation! The same is true
for an electric car. Adding even minimal amounts of insulation and
plugging up drafts and leaks will make a major difference in how much
heat you need to produce.
