What time does cheaper EV rate apply on Charge Anytime?

Thanks for replying. I still don’t really understand why you would use the boost/immediate charge function at a higher rate. Surely you can just set the time you need the full charge to be reached for one,two,three..hours time and it will start charging immediately (at the lower rate).

I think the boost function is to be used in case your situation changes and you need a top up charge quickly. The timed function doesn’t necessarily switch on full immediately 

I understood that the system will charge when electricity is low carbon/off peak - so it won’t necessarily start charging immediately as you suggest @craig310 

It might be useful to know roughly when the “green” times would be, so that you could know when to plug in your car. If it’s going to be roughly after 10:00pm say, then you just need to remember to plug in before bedtime. If it’s going to be greener at 4:00pm, then you might need to plug in between daily journeys. Many of us would not just by default plug the car in after every journey, especially if you need to position the car in a particular place on your drive.

The thing is @lee_surrey the green ‘slots’ vary and so aren’t exactly the same. 
You can take a look at the forecasted green generation times from National Grid for a clue.

They feature on an app too

Thanks for your answer @BPLightlog. I can see that it’s a little unpredictable as to when your car will charge. I suppose what I’m trying to work out is, what happens if there are no slots designated “green” in between you plugging in and the scheduled “charge by” time. For instance, if I plug in my car at 10:00pm to be charged by 8:00am the next morning, what will win out? a) My request to have my car fully charged, or b) the network’s need to be “green”. And if the answer is a), then would the car just get charged at normal household rates? And if it’s b), I would be pretty annoyed if there had been no green slots overnight and my car didn’t have enough charge to go to work.

It seems that, as the marketing blurb says “Charge Anytime, the clue’s in the name” what it’s really saying is that it’s not Charge Anytime you want, but Charge Anytime Ovo wants.

Thanks,Lee.

On the marketing ‘blurb’ you will see the note on ‘greenest’ times rather than green .. they say

4 Our smart tech aims to charge your car when the grid has more renewable energy in it, within the time you’ve set. Meaning it’s less likely your EV will be charged by energy from fossil fuels. 

@lee_surrey your scenario is always option a. If you set a ready by time, your EV will be charged by that ready by time at the discounted 10p per kWh. You don’t have to worry about the green slots, it’s all done for you. If there are none, your car will still charge and at the lower rate. The only time you will be charged the full rate is if you select ‘urgent charge’. 

Thanks guys. This is exactly the type of certainty I’m looking for. So basically, it will charge any time you want, at the 10p/kWh rate, as long as you put in a bit more effort and modify your “charge by” time for that day. It also gives you the choice to be “greener” too by setting a longer “charge by” window, like overnight, to allow the network to use greener power.

I just tested this theory and at 2:00pm I plugged my partially charger car in and told the app I needed the car by 2:30pm. After about 5 minutes, it started charging and continued even past 2:30pm. My Ovo app also reported about 50p increase in the amount I’d saved, proving it was using the correct 10p/kWh rate.

Thanks for all your help,
Lee.
