In its obsessive desire to promote the virtues of electric cars, the BBC proudly showed us last week how its reporter Brian Milligan was able to drive an electric Mini from London to Edinburgh in a mere four days – with nine stops of up to 10 hours to recharge the batteries (with electricity from fossil fuels).
What the BBC omitted to tell us was that in the 1830s, a stagecoach was able to make the same journey in half the time, with two days and nights of continuous driving. This did require 50 stops to change horses, but each of these took only two minutes, giving a total stopping time of just over an hour and a half.
Add in the effect of cold:
All batteries deliver their power via a chemical reaction inside the battery that releases electrons. When the temperature drops the chemical reactions happen more slowly and the battery cannot produce the same current that it can at room temperature. A change of ten degrees can sap 50% of a battery's output.
You've just lost 50% of driving range (assuming that you've dressed warmly and don't turn to frivolities like the heater).
You may be pardoned for not being especially impressed.
