Anyone else getting lower than expected amounts from Charge Anytime ?

I have a Kia Niro EV and a Pod Point charger.  After some initial incomplete transactions, I now seem to have the system working OK, but the savings are lower than expected.

To avoid peak rates, I started the last two chargings at around 1:00 to 1:30 am each time, with the car itself set to charge to a maximum of 80% - both times from existing levels of around 40%.   As expected, the details shown by my PodPoint App show charge amounts of 30kWh each time over around 4 hrs each time - so finishing well before 7 a.m.

For 30 kWh the Charge Anytime rate of 7.07p/kWh compared with my OVO rate of 27. 07p/kWh gives a saving rate of 20p/kWh, so I expected to see saving of around £6.00 for each charge.   However, in my Charge Anytime App, savings are shown as around £4.00 each time.

When I sent copies of my data to Charge Anytime at OVO, I received a reply containing the following:

Comparison with vehicle manufacturer and charger apps have in some cases shown discrepancies, that suggest customers are missing out on savings accrued from Charge Anytime. It’s worth noting that in each of these situations there are no absolute truths as the vehicle and charger manufacturers will all estimate figures in a different way, with varying accuracy.

 
Environmental factors also come into play as the vehicle might end up using power provided by the charger to precondition the battery to a optimal charge state, which we can’t account for using the telemetry we receive from the vehicle.
 
Rest assured that energy accuracy will continue to be an ongoing focus for us, as there will always be more ways to develop and improve how we work with the data that is being sent from your vehicle.
 
Having seen the programmes about Sub-Post Office managers being told that they were the only ones affected by computer problems, I thought that I would ask here whether other users are experiencing similar problems.

There are a couple of points:

 

Is the Kai App also showing the energy used in any environmental pre/post-conditioning which could happen outside of the charge times? My Zoë does that. It can draw anything between 750-2,000W for a period of time to bring the battery temperature up to what it wants but this is always outside of the set charge times.

 

The charging process from a 7kW charge point will be about 90-92% efficient (due to the car’s inverter inefficiencies and system power consumption) and may or may not be a factor in this. For instance putting 30kW hours into the battery will need about 4 hours + 10% or 4hrs 24 mins.

 

What you actually need to know is the power drawn through your domestic meter from Ovo’s HH data during the charge times set up by Charge Anytime for that session. As far as I have read the T&Cs anything used outside of that time slot will not be deemed as charging the car and will not qualify for the discount. What could be difficult there is how to interpret HH data where the charging start / stop is not exactly on a HH boundary unless Charge Anytime only uses HH boundaries. That I don’t know.

 

I hope that helps but also hope you get some feedback from someone who does use Charge Anytime.

This post prompted me to check my consumption data and in that respect I can’t fault Kaluza/Indra which match fairly closely to the smart meter. What had me scratching my head was that the charge anytime rebate calculated by Ovo was higher than I was expecting by about 20p. Unfortunately, if applied here it would only make it worse. So in case anyone else is making the same mistake could I admit to it to avoid any further confusion.

I have always assumed electricity rates were quoted before vat. So my standard rate is currently 23.34p before vat. My error was in assuming the charge anytime rate of 7p was also pre vat. This is not the case, it includes vat, so before vat the rate is 6.666p(recurring). So to calculate my rebate:

23.34 - 6.66667 = 16.67333

So on my total charging so far this month I have earned 

0.1667333 * 41.9 = £6.99

 Ovo reports £7.01 The 2p is probably down to the Kaluza app only displaying to one decimal place.

Hi all,

 

I’m still trying to make sense of ChargeAnytime and the charging values compared to my BMW app.

I’ve set the CA app to charge the car to 100% (recommended by BMW for the i3s) and have the BMW app ‘Charging mode’ set to charge immediately, I’ve done this on the basis that the OVO app will send charge to the EV when it wants to and the car will then accept the charge but if that’s not correct then please advise.

As an example here are 2 days figures from the BMW app and OVO CA app:

27th February: BMW app shows 19kWh charge over 7h48mins whereas the CA app shows 7kWh charge.

28th February: BMW app shows 18kWh charge over 7h20mins whereas the CA app shows 15kWh charge.

All help appreciated 😢

Charge Anytime is run by Kaluza (an OVO associate) and appears to run similarly to Battery Boost.

"All electricity used will initially be charged at the normal unit rate".

A monthly credit is then applied to your bill  reflecting the cheaper rate.  In the case of Charge Anytime it's 7p per kWh (Battery Boost is 10p per kWh.)

The difficulty is trying to reconcile your usage with the amount of monthly credit appearing on your bill.

I have three months of data usage downloaded to Excel and cannot reconcile the figures. 

You cannot talk to Kaluza, only the Battery Boost (or the Charge Anytime team).

I'm afraid it doesn't shed too much light on your particular problem but it's an interesting Kaluza coincidence.

Has anyone on the forum had the correct reimbursement for either Charge Anytime or Battery Boost?

Many folks get reimbursed correctly. This is probably a BMW specific issue so I’d suggest checking with the Charge Anytime team who can dig the logs.

Just a note to mention though. Kaluza is primarily made up of engineering teams who can’t access your account. Even if you could talk to them, you’d make little to no progress anyway.

So…

I can't talk to Kaluza.

I can't get the logs.

I've had no contact from the Battery Boost team.

I've hit something resembling a wall?

I will ask the Forum Moderators if they’ve got a contact number for the Battery Boost team at some point. Certainly, the Charge Anytime one is 0330 175 9678. This is the one you’re after. If Kaluza needs to get involved, the Charge Anytime team will raise an escalation on your behalf.

But as mentioned, Kaluza is mostly back-office engineering teams who can’t help you. The logs, meanwhile, are massive and often deeply technical. Unless you have the right tools to parse them, they’re often unreadable - needle in a haystack stuff.

Ok thanks. Look forward to the number.

It's a bit concerning that the logs are massive, technical and unreadable.

Does this mean we have to accept what OVO/Kaluza offer as a monthly rebate with no possibility of scrutiny?

It’s normal for logs related to almost anything to become gigantic - that is the idea after all. To log everything that happens. Hence why you need tools to drill down to just what you’re after.

I emailed 'ovocharge@ovo.com' last week asking for more info around charging costs but no reply yet

If you wish to follow up, you can also call 0330 175 9678. That’s usually the faster option anyway - the team often picks up rapidly.
