I am watching a YouTube video about V2G from the “Everything Electric show” and during the discussion it went on to talk about people who need electricity supply all the time due to their illness. The girl went on to mention motability was involved in discussions relating to the topic. That got me thinking that motability may, in the future, supply V2G or V2H chargers, which are very expensive at this time, to those who need constant electricity even during a supply outage.

Do motability do anything at present for those in this situation?

Has anyone asked motability about V2G chargers in the past?

This is an interesting subject and one that would be incredibly useful in the event of power cuts when customers have life saving equipment needing power.

 

I’m not sure what cars are actually capable of V2G or V2H (Vehicle to Home) but the equipment needed for two way power isn’t cheap.  I honestly believe in the future this will be a standard and potentially a prerequisite for  Scheme charger installations but we could well be looking beyond the time I’ll be driving or even around to see it.

Mark I agree it is a topic worth discussion and I think it will be arriving over the next 5-10 years. According to the YouTube video California is mandating all cars in their state must have V2H capability by 2027. Once car manufacturers are forced to supply in one location it’s likely they will go the whole hog and do it for all their cars ?.

Anything i post over three lines long please assume it is an article lol.

That’s part of what it will need.  I see it as a 3 part process:

 

1 Cars capable and available.  Without a car capable of sending as well as receiving high current loads over AC then the rest is useless.

2  Chargers.  Not only smart enough to know when it’s required and when it’s best to recharge but also capable of communicating with the car, grid, supplier and the smart meter.

3  Cost.  This can not be a luxury for the rich, to be successful it has to be at a price that Joe Public can easily invest in both car and charger up front in able to save on electricity prices and have that personal power security in a world where the ongoing power needs are only going to grow as technology continues to progress into every single aspect of our lives.

Many newer EV’s on the Market have the capability of whats known as “Bidirectional charging”, which will be the gateway for V2G and V2H. A vehicle with Biderectional charging capability, allow’s the car to be charged with AC electric from your wallbox via the onboard charger in the car converts it to DC voltage and charges the battery unilateraly (AC toDC converter) An EV fitted with a biderctional charger simply allows the DC voltage stored in the battery to be used to power your home or supply the electrical grid in the same way as feed in tariffs are used with solar PV. For this to happen you now need to covert DC to AC by means of a DC to AC coverter, which can be built in to a specifically designed EVCP, as a stand alone unit next to your EVCP or built within the onboard charger of an EV, allowing the EV its self to convert AC-DC-AC, sending power to your consumer unit or powerbank, such as a Tesla powerwall or soon to solar PV systems.

EV’s such as Hyundai Ionics and Kia EV6 are fitted with bidirectional chargers feature asimilar Vehicle to Load which allows you to power a kettle in a layby for example or power equipment in the home, using upto 80% of the vehicles battery using standard socket built into the car or a have a V2L adaptor that can be used with the car’s charging port.

At the moment vehicles with a CHAdeMO charge port can support bidirectional charging. The UK along with Denmark and the US have been trialing Biderctional charging to power houses and offices. In time Bidirection charging will become availble to other charge port standards, such as CCS2 V2G which I believe Austrailia is adopting it – well part of it!

For those with or thinking of having an EV with Bidirectional charging, you could use V2L to power dedicated socket/s or via a change over switch to power basic equipment in your home such as lamps, TV or kettle or indeed medical equipment.

As part of the government smart charger act, its their longterm goal for implementing V2G, to enable vehicle connected to the networt to help the grid on the odd occasions where peak demand cannot be met by the grid alone or via feed in tariffs at normal times. Its worth noting updating Europes ageing grid to todays standard is an impossible task. Where as the EU is spending billions digitaliing their grid the UK are more wisely adopting the said system. However given the high cost of Bidirectional EVCP’s I can’t see it happening soon.
