Re: hobdrive - and i-MIEV ion zero, show electronic control units, reset errors

Is there any particular reason why Hobdrive can't work with Bluetooth 3 adaptors on iOS when other apps can ? Especially when the same adaptor works with Hobdrive under Android.

I don’t think the MX+ is BLE only “standard” Bluetooth, so I guess it won’t work then.

Re: hobdrive - and i-MIEV ion zero, show electronic control units, reset errors

A quick question for Serhge - I already own the Android version of Hobdrive and use it both with an OBDLink LX and OBDLink MX+. However the Android device is a tablet and is often not in the car and I would sometimes like to take a quick reading (such as traction battery cell temperature) using my i...

Re: not charging my iON, cell or CMU or BMU problems

I appear today to have confirmed that the MUT3 can renumber CMU BMS PCBs I actually thought that they would renumber themselves, using a daisy chained pair of wires between each CMU. Are you sure you needed the MUT3 for this? Perhaps the MUT3 is needed to "kick things off", and the CMUs t...

Re: MCU 20A 450VDC fuse investigation

2.4kV ?

So the original 2kV caps would probably suffer a failure while my 6kV caps would survive in this scenario ?

Re: Troubleshooting and repair for On-board Charger (OBC), DC-DC Converter

Here is a simplified functional schematic of the OBC, MCU and Pack, showing details of the HV DC Output section with the snubber caps and MCU fuse that seems to blow. The snubber caps in my OBC were definitely 2kV not 3kV as shown in your diagram - one was undamaged and easy to read. I fitted 6kV r...

Re: Under the Cover--an Inside Look at a 2018 On-Board Charger (OBC2)

i think if you were to proactively replace the 20A MCU fuse as a maintenance item, then your old OBC would work just fine for a good long time. i'm still doing research on the failure modes. i'm struggling to understand how the MCU fuse could experience an over-current condition and blow, without t...

Hi DBMandrake, Glad to hear you're up and running again, Can you tell me what potting compound you used or even better provide a link for it? Think my board is a bit worse off than your one but again with the help of the great guys in this forum it should be sorted soon, Sure no problem. It's not a...

Re: Troubleshooting and repair for On-board Charger (OBC), DC-DC Converter

Good news. :) The fuse finally arrived today and the rest was a bit of an anti-climax! I fitted the fuse, put the cover back on the MCU, refitted the traction battery safety link, reconnected the 12v battery, plugged the car into charge listening for a bang but all I got was charging. :D I checked t...
