EV general discussion

Finally have power back on, a day earlier than anticipated, those SSEN engineers don't waste time!

The Vehicle To Load worked wonders, all EVs should have it.

They should offer true V2H, G and L. Slow standardization is too blame as lack foresight about how quickly BEVs would become a solution to wider issues when trying to make a more sustainable future

I agree, quite a few risks involved I hear with true V2H - house earthing arrangements, subpar electrics and the such like. As you say it can be overcome with standardisation.

It’s really no difference to any off grid capable battery system you can buy off the shelf of which thousands are installed every day in the U.K.

You only need to worry about earthing if you use the Earth provided by the grid and you wan to run in off grid mode.

If you go into off grid mode, you just need an earth spike or two, it’s nothing new or even expensive. Some houses don’t have an earth provided by the grid and will have an earth spike already installed.

The other thing you need if you want to run off grid is you need a mechanism to physically disconnect from the grid if there is an outage. If you want automatic (sub 20ms to failover), It’s about £900 of kit, if you are happy with manual then it’s under £100 of parts.

TLDR, the regs exist and the tech exists and has done for a long time.
 
I have a 3 pin plug socket under the rear seat found it earlier. Wonder if it will power my laptop….

According to Google it is pure sine wave (so should work fine with a wide variety of devices - unlike the modified sine wave output on some vehicles) and capable of 2-3kw output.

People are much more likely to hook up V2H with a "suicide" cable than typical with other systems which may make manufacturers wary, but yeah no reason why it can't be done properly.

practically manufacturers are still cagey on what export limits they might impose on v2g cars to assure battery warranty,
and if the car has an inbuilt 7/11kw invertor, that will be an interesting warranty claim area - my car is no longer supplying the house.

Like solar/batteries installs need the details on what effective electricity unit cost would be amortizing initial premium of a bidirectional charger.
 
My Cupra Born 77kWh allows V2G and V2H but limits this to 10,000 kWh or 4000 hours. You also need a compatible charger installed. It’s not something I ever see myself caring about.

The 58kWh versions do not allow this.
 
I’ve been using V2H for about a year, when it works it’s incredible but it’s not as reliable as I’d like it to be. The unit I have is from Indra and it only works on Chademo connections, hence why I have a Leaf.

Just checked it, it’s charged the car overnight on cheap but doesn’t appear to have switched back to Loadmatch at 530. Turned unit off and back on again, manually on the device outside and it’s happy again.

Is that lifetime?

If so that’s rather stingy to say the least. I’ve only had my hope battery since Jan 2024 and it’s already done 5,500kWh.

That said I’m not sure why you wouldn’t use it if it was something that was actually available. V2H will be come a standard charger feature eventually so you might as well extract the value from it if you can, particularly if you are leasing.
 
I would say a vehicle as a house power source would be purely emergency use only. So 10,000 kWh isn’t that bad in that context.

I’d suggest people would want to use it in leu or to supplement a home battery.

For example I’ve got a 13.5kwh battery, if I had a v2h capable car, I could probably get away with a smaller battery. Not only that, my battery doesn’t last the day in the depths of winter as I have electric heating (heat pump) so the car battery could plug the gap and keep me using the cheapest possible electricity.
 
My OHME Home Pro has been throwing up error messages on and off since Monday but was consistant since last night so I wasn't able to charge the Leaf. I contacted OHME this morning via chat which seems to be the only way to get in touch if you don't use social media and first you go through a AI bot that asks you some questions and then passed me onto a support person. Told her the problem and charger ID and she said it's a overvoltage error as too much voltage was being supplied to the charger. It wasn't that much over so she reset the limits on the charger and all is good again. Start to finish took around five minutes. Out of curiosity I plugged in my power monitor and sure enough the house voltage is 251.6v compared to our normal which is around 244v. It's been like this since the storm that passed through here on Monday.

On a side note, I have had the Leaf for 14 months now and only found out on Friday that if I press the camera button repeatedly it cycles through the different views. Duh!!

if you've paid for the bidirectional charger you'd want to use the v2g capability everyday for supplying/offsetting electricity during your peak evening cooking time .
the initial vag limits of 10000kwh or 4000 hours discharge might be adequate for first owner.
