I agree that this commute isn't a good fit for a 24kWh LEAF (regardless of year) bar workplace charging, and maybe not even then. Having the heat pump will help, except that much of the time in the OP's winter the temps will be below the point at which the heat pump provides no advantage, and resistive heating will be used. Add winds and high rolling resistance to that, and it's too much hassle.
