Well, this'll screw up those oil companies' conspiracies to keep drivers dependent on their products!.... .... or more likely it is another graphene fantasy from Geim...

So are you guys in the States seeing prices at the fuel pumps dropping, like we are in the UK? ... maybe you've not noticed!! ;) Anyhow, the issue I see with the price of crude dropping is that it seems to be a failure of policy not to maintain some mechanism to give advantage to low carbon...

Given recent threads, there seem to be folks here who have crunched through quite some published materials on 'global warming'. So I'd be interested to hear if any of these publications people have read have addressed one conundrum I've never really been satisfied with, in all the discussion on...

Tesla Motors accused of bullying to grab key car charging sites in the UK http://www.theguardian.com/environment/2014/may/22/tesla-uk-utility-electric-car-charging-stations" onclick="window.open(this.href);return false; Reminds me of Microsoft. Innovative company, but commercially vicious...

I'd just like to clarify something, because I felt that the following, from another thread, was an unnecessarily dismissive POV on the viability of domestic hydrogen fuelling: That's only as long as a piece of string. What rate of compressed flow do you think a home-fueler needs? Yes, there...

Just unplugging the charging lead from my home charging station (I had one fitted with a Type 2 socket), at 16A for a couple of hours, and was thinking about the fact that the Type 2 Mennekes connector was warm, but the J1772 was completely cold. I'd hazard a guess that the plug was...

Just to mention; from another thread: The largest and also one of the most efficient (per unit area covered) solar farms in the world is the Agua Celiente farm in Arizona, which delivers 630 GWh per year from its 3.75 mile^2 site. So a 10,000 mile^2 site, on the same energy/land area basis...

I've been carefully studying the energy consumption and indicated charge/use in my Renault Fluence since I got it. Hardly surprising - any EV driver must do this to plan their driving. Anyhow, I have come to trust and interpret what the SOC and gauges are telling me and am happy that I can judge...

I have found a timer with a suitable nominal rated current that I want to rig up to my charge station, so that I can take control of when it is powered up. I'm not sure if it's relay is a SSR or a mechanical type. Let's assume it is mechanical, and so it can switch off at a cycle peak, for the...

I put this in this forum because this is to do with wall-to-wheel efficiencies. OK, so I have had my EV (a Renault Fluence*) for a few weeks now but only tried charging to 100% over night, last night. Previously, I just put in as much as I needed for my next trip. One might casually presume...

I have, today, been investigating the power drawn by my wall charger for the purpose of establishing wall-wheel efficiency. It transpires that my particular wall charger unit draws 16 W of power while doing nothing, in its standby mode. So that adds up to 140 kWh per year, while I am...

I have seen some web pages reporting the [2012] Leaf battery pack as weighing 200 kg (without controllers). The Volt battery pack also appears to weigh in around 200 kg, but is 16 kWh instead of 24 kWh. But GM make a song and dance out of the fact that the Volt only uses 65% of its actual...

Hi. This might prove to be a technically complex question that I'm hoping can be summed up with just a bit of simple advice - because it should result in a simple decision as to what SOC to recharge at! Having searched around for tech info on the internet extensively today, I do not appear to...

If a simple current clamp is used to measure current drawn during EV charging, I presume this'd be accurate only in so far as there was no power factor correction to be made. So my question is; when charging an EV with a 'typical' on board charger design [I don't know if there is, yet, a...

Hi Guys. I'm in the UK and have a Renault Fluence ZE. I've been lurking for a while, seeing what the 'Leaf' experience is like. I signed up mainly to access the 'search' function here (... can't search unless logged in, it appears!). OK, well, I'll dive straight into what I was looking for...
