If there was massive uptake, the issue would be the network. Our 20th century one-way grid is expected to be all things to all customers, but it simply wasn’t built to accomodate large amounts of two-way power flows. Australia's been having problems with this for a few years now in parts due to extensive PV uptake. Thats why I find the concept of a utilising car battery for home generation interesting as it nudges you in the direction towards self sufficiency.
True but the Netherlands also has a sane government and regulators that seem to have customers interests at heart
Whereas we got a herd of cats in the Dail and the Chicago Boys for regulators
Absolutely, my folks put in 5-6kw array in November and have generated more than they've used since, which is pretty amazing over the winter. No EV or heat pump yet though
Can't imagine how much they'll be ahead by next winter. They're hanging onto the backwards spinning meter for dear life🤣
@the_amazing_raisin "This is the kind of scale that Eirgrid would be more interested in rather than a bunch of domestic customers exporting a few kilowatts whenever they feel like it"
You'd be surprised. I recently saw some figures for domestic micro PV generation in the Netherlands on a bright day in winter and it is one of the major components of electricity production now. There is a lot of power in small installs once they run into big numbers. And PV over there works less well than PV in Ireland. Many houses in Ireland could generate their entire yearly electricity consumption (or more) from 12-16 panels on the roof
Based on the Quasar 1, I'd be expecting a price of around €5k, pretty pricey
I agree with @unkel that AC V2G is better for domestic scenarios, much cheaper installation costs and you have the advantage that the inverter is in your car, so you've a portable power pack anywhere your car goes
DC V2G is really suited to big commercial fleets which can make a lot of money exporting to the grid. The main advantage of DC is that in theory you can discharge as fast as the car can charge, so 150kW should be possible with the right equipment
If you had a fleet of trucks plugged into chargers every evening you could export several MW of power at once, assuming you had a suitable inverter. This is the kind of scale that Eirgrid would be more interested in rather than a bunch of domestic customers exporting a few kilowatts whenever they feel like it
It's called ICEing a charger 😁
CCS Denial of Service attacks, don't think I've seen anything like this reported before.

$1310 plus install costs for Ford's bi-directional 10kW home charge point is reasonable enough, I'd gladly pay that if my car(s) had bi-directional charging enabled
Ford have a released a bi-directional AC charging solution in the US for the F-150 Lightning EV. Make sense given its battery size for the extended range (131kWh).
The new Quasar 2 Wallbox also recently released (again in the US) a DC charger that has a CCS Combo plug charging at 7.4kW/32A or 11.5kW/48A. Im not aware of any supported vehicles at the moment. And I would expect it to be pricey.
Will be interesting to see where this convergence of technologies heads in the long term.
DC bi-directional charging is no good. First of all there is not yet even any standard for CCS bi-directional charging. And DC chargers in the home will always be expensive and there is totally no need for it. AC at up to 22kW (if your house is 3 phase) or 7kW (if your house is 1 phase) is adequate. I can't see how there are any regulatory issues with AC either, it's working the same way as if you have a home attached power wall.
ID cars can only do DC bidirectional charging at the moment. Well actually they can't do any V2G at the moment but they have the hardware for DC V2G already. Software to unlock it is supposed to be out end of 2022, apparently they're waiting on the updated CCS2 spec before rolling it out
I'd much prefer if VW did AC V2L like Ford, MG and Kia/Hyundai. It's definitely the way the market is going and seems much simpler in implementation because you don't need to worry as much about grid integration
Speaking of which, Deiss mentioned that the biggest hurdle with V2G wasn't technology but regulatory, since they have to customise the solution for every country just about. I could very easily see VW looking at Ireland's ridiculous set of rules and just not bothering 😬
This is actually something I was thinking would be great for emergency vehicles and vehicles that have to work in remote areas
It would be fairly simple to build an EV and then bolt on a generator to charge the battery. Again the i3 is the perfect example
I've seen generator modules that fit under a truck which could be an option. They don't need to be particularly powerful, the idea being that they try to keep the battery above a certain threshold. While the vehicle is cruising the battery is charged but if it needs to accelerate then it can dip into it's battery reserve
You could even make a modular system so you could easily swap out a diesel generator for something like a fuel cell or more batteries down the line depending on the need
Again to stress, I think it's only really worthwhile for specialist applications. As we're seeing most normal haulage jobs can be handled on battery power alone
Given their is no tailpipe, and the vehicle itself is not emitting, I think it's fair to call it a zero emission vehicle.
They should be labelled "zero tailpipe emission" vehicles, having said that I've driven around 542kms this month on zero emissions as power fed from house PV panel generation
Here in Athlone they are all electric too, they finish the day with 60% SOC but policy is to charge back to 100% every night which I disagree with from a BMS perspective but what do I know
I'd say more theoretically than technically, yes it is possible. You have the battery as a buffer of energy which you replenish with the REX. Not that this truck will go very long distances.
As fun fact did you read about the truck that doesn't need to be charged?
Very light on the details about that pilot scheme. But they rightly stress the huge importance of V2G in the renewable energy revolution. Fair play to VW, hope they can roll this out to the public very soon. A quick google shows that only the largest (77kWh usable) battery ID (MEB platform) range cars already have a bidirectional AC charger on board?
VW starting a pilot scheme with EV grid integration
I'm thinking truck, lets say a Volvo fh Electric 6x2 truck, 46 ton unit, towing a timber trailer, lets say there is no weight issue, in adding a generator of up to 1 ton on to the trailer, could that truck then work, and charge itself, on the move, but mostly in down time, example loading in a forest would take an hour,.
Technically possible?
lets say a 100 kva lpg generator
Well it's to be expected when they list the cars they are targeting.
The design language should filter down to the "cheaper" models though.
... and expensive!
That looks amazing.
Practical solution, but would never be accepted by Councils here given our BS compo culture/industry in this country.
They also have electric Mercs. Our local DPD van is electric as well. I think it is Nissan
Oh, you're right. But there are other solutions being tried such as the chargearm. See here:
https://chargearm.com/
Is it really so common in other countries? The link above talks about a cable gully trial by one local authority in the UK. I haven't seen them installed anywhere so far.
People may well try to do that. However, it shouldn't be used as a stick to beat law-abiding citizens looking for a safe solution to a problem that is about to become very common and which has been easily dealt with in other countries already.
Looking at how some people in this country try to privatise the space in front of their house with traffic cones and all kinds of other obstructions, I am not sure allowing them to install a cable gully or anything else is such a good idea.
Wouldn't call it a cheat, removing tail pipe emissions from cities will save millions of lives.
But yeah, of course we will need to make the grid much more renewable than it is now. And soon.
