  1. Energy Tariffs like Vehicle-to-grid (V2G) systems

    General EV Discussion
    Is it worth doing any of these? Static time-of-use energy tariffs Different price bands for electricity throughout the day Dependent on the time of day, day of the week, or season Higher rates are applied when demand for electricity is greater In some cases, installation of a smart electricity...
  2. Did Brian steal my energy?

    General EV Discussion
    As I do every few weeks, I drove my LEAF down to Birmingham and back this weekend (21st October). Now this was the day that storm Brian visited the UK. Now usually I get to Tibshelf with more that 20% in the tank, plenty to move on to Trowel if Tibshelf is busy, or bust. This time I was down to...

    Tesla Model S
    With my last couple of ICE cars I've kept a log of tank-to-tank mpg as a way of measuring actual fuel consumption (the on-board estimates usually proved to be over-optimistic). I've been trying to do something similar with my Model S70 RWD which has done a modest 1780 miles over 3 months (around...
  4. Charging pole adapter questionnaire

    General Charging Discussion
    Hello people! My name is Koen Elands and I am a third year automotive engineering student at the Technical university of Eindhoven. For a project we designed an adapter on a charging pole which will be more energy efficient so it will reduce the costs of charging and it is better for the energy...
  5. Effect of cold weather on energy usage

    Nissan LEAF24 & LEAF30
    Just downloaded my last 11 months figures off the Nissan website: very clear evidence of the winter/summer effect on range and energy efficiency for my 2013 Leaf: I'm driving about 1,000 miles a month or so: June 2015 figures are unavailable due to a carwings glitch: Jan/2016 0.34 kWh/mile...
