Inverters at homes (and other charging stations?).

Software so EVs know when to "buy" and "sell" (the latter up to a limit so they don't go flat).

A way to measure when you bought and sold, and at what rates. Smart meter in the home? What if 'selling' at a remote station?

Variable tarrifs. At least "low" (5p/kWh?), "normal" (15p/kWh), "high" (25p/kWh). Govt would probably want to limit the 'high' cost for social reasons.

Anything else?]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=14310&Focus=243217#Comment_243217 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=14310&Focus=243217#Comment_243217 Tue, 28 Jun 2016 14:07:59 +0100 SteamyTea Also how about regional differences. Why should someone in Cornwall not be able to charge a car at a cheap rate because some farmer is using power in the morning (there is a 40 minute solar time difference). Similarly, what if the next town to you has a large arc furnace that is trying to take advantage of cheap rate power, that will just flatten your batteries for you.]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=14310&Focus=243247#Comment_243247 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=14310&Focus=243247#Comment_243247 Wed, 29 Jun 2016 12:52:15 +0100 GarethC
Trying to guesstimate how the ability to buy leccy cheap and sell high (say at my indicative rates) might affect the economics of EV ownership. i.e. what 'profit' might be realistic, and would it pay for the inverter etc, or make EV ownership generally more attractive.

But I'm failing. Too many variables. I'll come back to this, but can anyone with more knowledge (low bar) come up with an answer in the meantime?]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=14310&Focus=243265#Comment_243265 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=14310&Focus=243265#Comment_243265 Wed, 29 Jun 2016 16:00:58 +0100 ringi https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=14310&Focus=243274#Comment_243274 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=14310&Focus=243274#Comment_243274 Wed, 29 Jun 2016 19:53:40 +0100 GarethC
