Why not use a auxiliary battery heating system that uses some kind of fuel (i.e. biofuel) for this scenario? The amount of fuel needed to heat a battery to its optimal operating temperature during cold weather is probably orders of magnitude less than the amount of fuel needed to propel a truck, so the carbon emissions would be minimal. The same system could also be used for driver cabin heat.
