London Electric Vehicle Chargers Proposal.

davezawadi:

Chris I find your calculation curious in that you suggest an electricity consumption for an electric car which is tiny. 4kWh per 5 miles is optimistic if there are any hills, wind, acceleration or whatever on the route. Charging at stations may be a good idea, but at train pricing rates probably unaffordable.


 

4kWh per 5 miles is extremely pessimistic.  It may be true for a large HGV.  But for real electric cars on real roads, it's nearer 4 miles per kWh.  Maybe 5 miles per kWh for a very small efficient car, less for a big one.  The latest cars coming on the market have batteries of around 50 to 65 kWh, and have measured ranges of around 200 to 250 miles.


The only caveat is that the range does drop in winter.  How much depends on how cold it is, partly as the batteries lose efficiency, and partly as people turn the heaters on.


Just look at the published specifications of any modern EV, measured against the latest official range measurement standards.
