We’ve all heard the stat, your car spends 90% of its time parked so if a large chunk of EVs were vehicle to grid, or V2G, enabled in which electrons are sent backwards and forwards between the battery and the grid, that could supply all of the world’s short-term grid energy storage requirements by 2030. Sounds good right?! But it’s not totally straightforward. The hardware exists, but standardisation, communication protocols and getting all the car companies, charging operators and energy companies and various grids on the same page has proved somewhat of a stumbling block. So what do we need to do?! In this episode Imogen finds out what it will take to get to this electric vehicle utopia and when we can all expect to enjoy a little bit of V2G!

The only reason it has not come sooner is because some car companies also have home battery products to sell.

Chademo is still supported but CCS became the much preferred format and now the NACS format is set to replace both of them. However, the idea of exporting energy from your car is here to stay.

The problems with conventional V2G, besides the technical and cost issues. It is logistics. EVs are parked at various locations, bidirectional charging would have to become ubiquitous It is a very long way off at best. And who knows if it will ever happen? Plus that 10 to 20 percent, when you're driving tends to be when the grid needs it. So it still will just be a marginal option at best. A far more effective option is V2G, utilizing modular (or variable sized) packs, via battery swapping stations. Since the excess battery capacity is at a swapping station, where it can do V2G balancing. Which is already being done at battery swapping stations in China. Conventional V2G is just a niche feel good option, that's just not scalable in most cases.

@reginald7214 3 месяца назад

Actually there are far more interesting battery swapping networks, than what NIO offers.... For example, CATL's modular battery swapping network.... But since NIO is rolling out in Europe it tends to be the only one that gets coverage In Europe.... But the competition is forcing NIO to become more innovative, such as agreeing to create a battery swapping standard with Geely and other automakers....

@dreamcatcher3748 3 месяца назад

Thanks for another informative video! I can't wait until all of this V2G, V2L, V2H just work no matter what you buy. I've been holding off on buying an EV and solar for my house until this is worked out and standard (along with some of the newer battery tech). My dream is that when it is all working, can add solar to my house, a smallish home battery, and use my car as a battery too, at night. We have lots of sun each day where I live, so everything can charge during the day, and then the batteries can be used overnight. I doubt I would furnish battery energy back to the grid because of the impact on the battery's life UNLESS the local utility paid a premium for it. But I'd be happy to sell them any excess energy I generate during the day after my battery and car are topped off. Most of my neighbors that have solar work during the day away from home. They don't have batteries, so most of what they generate from their solar is sold to their utility at wholesale prices. At night, they have to buy energy from the local utility at retail peak prices and then charge their vehicles in the wee hours at retail off-peak prices. So they are still buying lots of electricity from the local utility each evening and night, and getting a little money back due to the energy they are selling the utility at wholesale prices. WHEN V2Everything is available, I don't need my local utility as much, and a lot less energy will be racing around my neighborhood. Lots of people mention how our grids are undersized for the future. I think this technology will mitigate some of that as people like myself become more self-contained and use the grid less and less.

@@nc3826 How does battery swapping help me use my car battery to run my home? Battery swapping can only happen at a swap station. An EVSE at home which can take power out as well as put it in means the battery can be filled and emptied some every day to minimise grid costs. In our case it would stay plugged in for a month or more at a time in winter. Battery swapping is only relevant to fast charging on road trips.

@nc3826 3 месяца назад

@xxwookey Battery swapping stations, do bidirectional charging energy arbitrage, much more effectively, based on a database algorithms, than any home bidirectional charging. Plus it allows much lower capacity battery packs, to be utilized most of the time... And just swap in a higher capacity battery pack when needed. While conversely having an EV sit at home for months at a time is a relatively inefficient use of that technology and its carbon footprint. An appropriately sized stationary energy storage system would be a much more efficient use of resources. And is offset by that lower capacity swappable battery pack, which normally can be used to power a battery swappable electric vehicle. Battery swapping has a plethora of advantages, which tend to be overlooked in the West.

Plus they have developed the Gateway 2 so that it satisfies the requirements of grid operators in many different countries.

Although if people have range anxiety as things are, we can't really count on much of the baterries capacity to be actually loaned to the grid, so the potential comes with this big caveat. I'd guess something around 30% of EV batteries would actually be surrendered, and then there's the logistics of it all and the practical necessity for middlemen to come in and take a cut, making the prospects less convincing to the end user. Also, people would probably have to charge by day while they're at work and then V2G in the evening. This would make it harder for overnight level 2 charging to suffice for people's comfort. So, probably a step forward, but not a game changer.

In UK we've been outsourcing electricity for at least a hundred years or so ... and gas ... (pipe or tank) ... or water. You might say we "outsource" the contents of our septic tanks as well as. If you added a power wall and/or V2L and solars (not quite so useful in UK) where's the cost saving if you include the equipment? Even in really atrocious weather UK doesn't suffer that many outages. Hospitals, say, sit on a generator(s). Some defence stuff might have two completely separate incomers off the grid from entirely independent connections, and a genny if Armageddon does arrive. Mind you most of us would have been exposed to a touch of gamma radiation and probably not too bothered about much after that anyway. Those in their own fall out bunkers will only be delaying things by a couple of weeks anyway.

Given that 7kW is enough for most purposes it seems to me that doing this the AC way will be much more cost-effective.

The controlling device in terms of whether power flows in or out is the inverter. That could be in the car, in your 'charger' (actually EVSE) or in your house. And (ideally) you can control that, or you can choose to hand over control of it to the power company so they can decide when to flow which way. I hope that makes sense. At the moment the power company or car company tries to sell you 'black box' paired device so that only they can control what happens.

I do follow the news, and things are looking extremely promising on that front. Even for purposes like Steel and Aluminum smelting energy demand. If your concern is V2L on the other hand.

Given that the world is likely to be battery-minerals and/or manufacture constrained for the next few years at least, it makes a lot of sense to use the car batteries for grid balancing rather than make all the batteries again.

We don't need a 'universal consensus' on anything beyond the comms standards, and those already exist. There can be plenty of different business and control models given open standards implemented in connection equipment. You are right that there is potential for other, cheaper, more static-appropriate battery tech to go on the grid, reducing the need for expensive mobile-optimised batteries to be use for this purpose, but the demand for storage is already very large in dunkelflaute periods, and will continue to grow as nearly every house gets a heat pump and nearly all the cars go electric.

I’m puzzled why they reinvented the wheel. V2H has existed in Japan for over a decade and it works. Many households have already implemented it. There is no magic to it with Chademo. For it to work with CCS/NACS the car manufacturers need to agree the required communication protocols and then device manufacturers will surely provide the necessary inverters like in Japan. That said people overlook one big issue and that is that EVs consume a lot of power when charging or discharging on DC. This overhead is so big that V2H isn’t a great replacement for a home battery which is much more efficient in this respect. Most V2H owners in Japan have been badly disappointed by how little power they actually save - in some cases even losing more power by being permanently connected to the car than their solar systems produce. So EVs need not only the right communication protocol but also some reengineering to run as efficiently bidirectional charging as home battery systems mostly do.

Having EV's offer V2x as DC output makes most sense, as should only require a software update to enable. Prior to the Nissan LEAF offering V2G option, the Mitsubishi iMiEV offered V2L option using an external "PowerBox" the size of an A4 paper ream (500 sheets). In 2012, this a great option for home power outage, camping, etc. Cost was reasonable, and the 1500 watt PowerBox was was portable at ~9 kg. An option to offload/charge via DC port could also transfer energy to an external energy storage, or too the EV. Once grid connections, come into play, particularly with AC, things get complex quickly. eg: AC signals need a way to manage and keep in-sync. The raw technology for converting DC to AC via an inverter is exactly the same as a solar inverter. Just slightly different management software.

@xxwookey 3 месяца назад

Using the DC port requires your EVSE to manage 400 or 800V DC which is currently expensive (although it probably wouldn't be if it was standard). Doing it over 240V AC is a lot simpler and cheaper and still gives you 7kW (single phase) which is enough for most houses. 3-phase 22kW is enough for any sensible house.

One other thing ref the notion of an onboard car inverter then that output would only be supplying the house mains phase (in UK). Google will help on the topic of how properties are connected to the grid in order to balance the phases. If a battery was charged away from the home on an "expensive" tariff then it would be an expensive way of doing the battery to home thing. All in all it looks as if most people are clueless on this topic and the entire nonsense is a case of technology looking for a home to solve a problem that doesn't exist. In fact it might be said that buying all this equipment to run a jome from a car battery simply shortens the life of said car battery. And increases the cost of running the home when the cost of a battery is factored into the equation. Nothing is really for free. This notion of battery backup is a bit silly in countries with a reliable mains supply. Perhaps that's why some car manufacturers steer clear of this "V2H/G/L" so the car battery isn't on such a brutal duty cycle working itself to death driving a home as well as the car? People who have researched why lithium ion batteries self ignite will know by now that there's an issue with "electrolyte degradation" which can cause heat to build up. For all we know that's what caused the three London buses to self ignite. Probably best to wait until hydrogen arrives before lashing out on power walls and the like.

Just not worth it for most people.

As Elon said: Batteries have limited cycles. Spend them on the car.

Can we please stop confusing people buy calling a EVSE a charger when it is not.. THX

The rapidly falling price of batteries , esp stationary batteries, is IMNSHO making the use of the car as a battery redundant. A battery that will do my whole house for a day is around £3k and could be £2k by end of this year. IOR £4k for a battery that will manage double my house load. Sure a car has far more storage but how often is that needed?

@reginald7214 3 месяца назад

Probably very infrequently. V2g during the day out and about or at work is good for earning a few bucks.

I'm willing to bet a decade from now, we will still be hearing how V2G is just around the corner. While V2G is already available in China via battery swapping stations. And it is coming to the rest of the world via the same path. Without most people ever realizing it. KISS...

@Brian-om2hh 3 месяца назад

There are already a number of V2G schemes operating in Britain. You just were not aware of them....

@nc3826 3 месяца назад

Jingoistic "awareness" of decades old V2G schemes, that have proven to be unscalable.... Is the problem, not the solution....

It powers your house ... *When it's at your house* . If your power cuts at 0830 and you left for..... "somewhere" in the vehicle at 0820, no battery.😊

She said the car would be used to bolster your houses battery storage, so if you have a Tesla Powerwall etc, the car would work as additional battery storage on the basis the majority of journeys are 10-30 miles a day, so well short of the kWH of the onboard battery.

If you have a small house battery, you could drive and bring home enough electricity to last you over the weekend. Nice.

@theunknownunknowns5168 3 месяца назад

Decentralised democratise energy. The rich are going to fight hard against V2G/L/H. As they already do against residential and community Solar plus stationery batteries.

How will shareholders make gains if energy is made everywhere and easily shared.

@keschris 3 месяца назад

Disappointing video, tempted me in with talk of v2h but focused on v2g. I don't want to buy a power wall battery when I have a 40 kwh battery sitting on the drive.

@reginald7214 3 месяца назад

Good point

@charleshill7184 3 месяца назад

You do, actually. At least, you do if there is a power outage and you want people at the home to still have some power if you need to drive away. As the interviewee said, you can get a small battery for the home and supplement with the car battery. Powerwall? No. Something smaller, like an EP Cube in the minimal configuration.

@@charleshill7184 I've not heard of ep cube, just looked it up, not sure it's available in the UK yet. Interesting concept of backing it up with the car, will investigate further. Thank you

Wouldn’t solar on the cars help? I’d like to convert my 2000 VW Cabrio to EV in the future if there’s great kit options.

@robinbennett5994 3 месяца назад

Not really, a car roof is tiny compared to your house roof. Put the panels on your house, where the weight and aerodynamics don't matter as much.

@Brian-om2hh 3 месяца назад

Waste of time. To get any meaningful amount of charge into an EV in a relatively short time (such as when you were parked), you'd need a solar array the size of a tennis court.
