Blue Smart Chargers IP22 pulsing voltage and current

I don’t know the specifics of this charger issue yet, I’m waiting to hear back from the director, but the Christmas to New Years period is also not the fastest moving.

So just generally;

We definitely appreciate end user reports, especially those that show effort in research (with links to others experiencing the same issue).

There are several “awkward” gaps in the process when something goes wrong

  1. When users know there is a problem, but we don’t.

  2. When we know there is a problem, but don’t know how big it is, or how to fix it yet

  3. We know how to fix it, but the fix will take some time to implement or roll out (if it’s a hardware change)

Quite often in that process there are also multiple potential pathways.

For example there is a hardware problem, but we might be able to resolve it with a firmware update.

That was the case with the Cerbo GX MK2 VE.Can port - eventually we resolved it low level with a hardware change, but we were able to resolve in 99.9% of cases even in old hardware with a series of firmware fixes. Many other similar cases too.

As a manufacturer, there are also stages on how we notify our networks.

For example sometimes we might need to notify our repair centres and give them the time, instructions and components necessary before making a public announcement and overwhelming them with enquiries they aren’t ready to handle yet.

That looks like to the end users like we are ignoring the problem, when actually people are working hard so the roll out of a fix is as smooth as possible.

For my part at least while there isn’t always perfect information, a best effort is made that everyone feels like we stand behind our products and do what we can to fix things when they go wrong.

I hope to come back shortly with an update on what’s next for these chargers.

When will the new improved batch of chargers be released for sale???

There is no announcement about a new batch.

Currently the issue isn’t documented.

Victron stated they are investigating the reports.

This isn’t going to happen immediately as it is the festive season.

They will report back here any findings.

Hi All,

Thanks for your patience waiting for more info on this issue.

We now have a preliminary beta firmware version that is being tested to resolve this issue.

EDIT - see latest post for info about the beta firmware test

This is specifically for Blue Smart IP22 Chargers with a serial number between HQ2511 and HQ2551 that show a pulsing output (voltage + current peaks) under low current draw conditions.

Units produced before HQ2511 and after HQ2551 are not affected, and do not show this behaviour.

Once we have completed the beta testing phase the firmware fix will be rolled out as normal.

If there is some instance for a unit between HQ2511-HQ2551 where the behaviour is still shown despite the newer updated firmware fix, Victron Repairs will arrange an alternative remedy as long as it is clear in the RMA that the firmware fix has already been applied and was unsuccessful.

However we expect the firmware fix will be successful.

There may be further updates as we get more information from units in the field and the firmware is finalised.

Again, apologies for the issue and thanks for the reports and patience in the resolution.

Hi Guy Stewart,

I have a IP65 Charger 12V 10A with a serial number HQ2519 and I have the same problem.

  1. There are current peaks in the charging (video showing the BULK phase in Low Current mode).

  2. The voltage in Normal mode should be max 14.4V. However, I have almost 14.7V (it`s too high voltage) in Normal mode (video). When I switch the programme to High mode, I have 14.7V – in High mode it is OK.

Is there a fault with the charger? In my opinion, the charger is not working properly.

What do you think?

Hi @Tomek

I’ll leave this post specifically about IP22 and reply in your new one about IP65

The behaviour appears similar, but for now the remedy is different

Anyone experiencing issues with IP65 please discuss here;

Hello there,

I’ve just finished testing the new beta update for my IP12 15A with serial number HQ2531(…). It helped with in 50% of the existing problem - the current is now not pulsing from min to maximum value which has been set - it’s now more subtle, but it’s still noticable because it double its value at the range 0.3-3A.
Voltage is also pulsing and is not stable at all in any stage.

Whole story of my unit is that I’ve gotten it with 3.63 version I belive, and it was working fine until in the ABS stage the current went under the 2.5A - then the pulsing started for both current and voltage. Before that the voltage was solid as a rock, and current in bulk stage was as well.

After update to 3.65 the pulsing was present in every stage, and for the current was in whole range.

If any questions will arise I’m happy to help.

Hallo,

After the firmware update, the problem persists. The voltage spikes are smaller, but it’s still not constant. Before the firmware update, charging in the bulk and early absorption phases was fine. The problem appeared over time. I’m sending you videos showing what it looks like. The first three are after the firmware update, the next two before.

Witam mam wersję HQ2528A2D4Z skaczące napiecie i amperarz mógłbym prosić o przesłanie poprawki do oprogramowania Pozdrawiam

Hi, HQ2522* here. Looks like current is fluctuating much, can go from 0.2A to 15A in few seconds. Its more intense in first few minutes of charging then cycle repeats (the appearance of 15A current is periodic). Looks like charger could not make it’s mind.

Attaching video: https://youtube.com/shorts/KYbGW0UeCHk?feature=share

Firmware: 3.16, bootloader 3.16.

Exact serial number: HQ2522TMYVF

Should I try some beta software?

Hi!
My BSC IP22 is HQ2534. I also see voltage and current peaks in float or storage stage. Could you point me to the beta firmware to see if it helps?

@guystewart

Hi @RheinSkipper @gregoryo @fotosikor

I have sent you each an email with the testing firmware

Witam mam pytanie jak tą poprawke zainstalować ?da sie przez victron connect?

Thanks, got it, however I already sent device to the Seller. Will need to wait if it comes back.

I installed beta firmware. But I still see fluctuating current an voltage:

Tak, da się. Najpierw z poziomu androida np. za pomocą aplikacji Files od Google znajdź ten plik i zrób uruchom za pomocą : Victron Connect. Wtedy ci się załaduje ten plik do aplikacji, a następnie najlepiej ściągnij sobie instrukcję i tam jest wszystko opisane na str. 49-53.

The beta software installed didn’t help. The charger was sent to the store today for a complaint. HQ2525

Dzięki udało sie zainstalować ale nic nie pomogło Pozdrawiam
