Real World Test of V2G Now Underway in Spain (w/videos)


At the end of April, in Malaga, Spain, Zem2All – one of the largest pilot programs dedicated to electric vehicles and two-way energy exchange between vehicles and the power grid – got underway.

The leaders of the project are Japanese company Mitsubishi Heavy Industries, Hitachi, Mitsubishi Corporation and Spain’s Endesa.  Endesa previously partnered with others to develop earlier V2G devices.

Zem2All’s fleet consists 200 electric vehicles – 160 Mitsubishi i-MiEVs and 40 Nissan LEAFs.  The charging network is made up of 200 charge points and 29 CHAdeMO fast chargers, 6 of which are equipped with the V2G capability.

Taking into account that, in Spain, there existed only 24 fast chargers at the end of 2012, Malaga certainly has to be Spain’s leading city now with 29 CHAdeMO fast chargers arranged in nine locations.

This four-year vehicle-to-grid project has a budget nof €60 million and one of its objectives is to conduct real-world tests of vehicles charging mostly from renewable sources and returning power to the grid at times of peak demand.

Detroit Electric was bragging about how their car will be able to do car-to-grid. The i-MiEV and LEAF do it today.

Sorry. I’m just not a fan of this. I don’t want the battery in my car to be drained to provide extra power to the grid. Not only that, I certainly don’t want to pay extra money for an EVSE that has this “feature.”


You will not going to pay. You shall be getting discounts for that.

V2G sugests that power drainage from batteries would be needed during peak demand. This happens very seldom and for very short period (miliseconds). Who cares if charging time increases for some seconds but general power blackout will be avoided.

Regular EVSEs / L2s won’t have that “feature”, as the on-board charger on current cars can’t feed anything back to the grid. EVSEs can implement (and some, like Blink units, already support) load shedding, ie temporarily reduce, pause or delay charging if and when grid conditions call for such measures. I’m not aware of this being used already though. I’d imagine that it would always be voluntary, override-able, and that utilities would provide some kind of incentive to whoever participates (cheaper electrons? free EVSE?), like is currently the case for the air-conditioning “throttling” program that at least one utility, PG&E, promotes. The CHAdeMO quick-charge port (Leaf, i-MiEV etc) already allows energy to flow either way, nothing to change there (software, at most). A quick-charger, V2G-enabled or not, isn’t something you’d buy for home use, so you don’t have to worry about that cost. If anything, V2G may allow companies offering quick-charging to do it cheaper eventually… E.g “Hey, we charge your vehicle for free, maybe up to 100%, but we may borrow back up to x kW*h so we only guarantee you’ll have 80% charge or more at any time. [Accept free] [Request regular charging] ?”. I’m not holding my… Read more »

Well, actually… that was fast 🙂
The article is a bit low on details, but it sounds like the only grid “interaction” there was in that case was (re)scheduling charges at more favorable times, not V2G.


I’m always astounded at the price of these studies. About $200,000 per vehicle/charge station. Boy, if you can’t make at least $40M profit you’re doing something wrong.
