Slightly off-topic, but might be of interest: I highly recommend two books by American writer Steven M Casey on true tales of design, technology, human error and the law of unexpected consequences: "The Atomic Chef" (Aegean, 2006) and "Set Phasers On Stun" (Aegean, 1993). Out of print, but...
Agghh! That's a real pity, as my friend's workaround sounded like it might do the trick.
Maybe a future MG firmware upgrade might offer the option of setting charging current (or power) in smaller user-selected increments?
I guess another workaround is to cut out the Zappi altogether when I...
Thanks for the advice and explanation on cell balancing - very helpful.
Boost mode isn't activated and there are no other limits.
I did a granny charge overnight, and I'm pleased to report the MGiSmart app is reporting that the battery has now charged to 100%.
I'm planning to drive to London...
Thanks.
This time I didn't repeat disconnection and reconnection of the 12V battery: I just sat in the car and started it up.
Not so many warning messages as last time.
Whilst it was booting up and sending warning messages, I turned the steering wheel fully left then fully right, and the...
I thought it was going to prompt me to turn the steering wheel to both extremes at the appropriate moment during the re-boot sequence; but it didn't.
Does this mean I've missed the opportunity to calibrate the steering and need to repeat the process of disconnecting and reconnecting the 12V...
Thanks! Worrying moment there: I thought I'd managed to brick the car!
What about the power steering? It's sending me alerts about this but hasn't asked me to perform a calibration, so how will it know that the steering is properly calibrated and safe to use?
So... I've just powered down my MG4 using the Safety>Power Off setting.
Removed the Negative Terminal from the 12V battery.
Waited a minute.
Reconnected the 12V battery and powered up.
When the system powered up, it only asked me to calibrate the 4 electric windows in turn.
Not sure how to do...
Hi - glad your system is behaving well at present!
I'm on Intelligent Octopus tariff, so it costs 7.5p/unit to charge my EV and/or Powerwall overnight, which is great; but when my system was working before these problems I could charge my car for free on sunny days from PV, and only use the...
Many thanks for your clear and thoughtful reply.
I hadn't appreciated the fact that overwriting user settings might be a necessary programming strategy to avoid loops, but from that perspective it certainly makes sense - even if it makes for a frustrating end-user experience ;-)
I've been...
Thanks - I agree there are all sorts of potential problems in using multiple apps and hardware and getting them to work together as intended without conflict; but this all worked fine for me till last week's MG firmware updates.
My requirements/expectations can't be that exceptional: there must...
Thanks for the link and workaround...
I really appreciate your help, and if this was a second hand car that I'd bought cheaply then I'd accept these kind of problems as part of the deal and have a go at fixing them myself.
However this is a 6 month old car that cost me over £ 32K to buy from...
Thanks for your reply. Apologies for my lengthy posts: I'm just trying to include as much detail as possible in case it is relevant and helps someone identify a possible cause or solution.
I had the MG4 Trophy LR from new last September, and it used to all work fine when trickle charging from...
Many thanks.
Just before I got your last post, I had just restarted charging again (required unplugging and reinserting charging plug, checking that Charge Settings on both MGiSmart app and in car firmware are both set to "Scheduled Charging: OFF" and "Target Battery Level: 100%", and toggling...
Tried again to charge from PV today in Eco+ mode, with latest versions of Zappi firmware and MyEnergi app.
The starting Battery Level was 86% with a Target Battery Level of 100%.
Charging started and continued without any problems until I diverted the surplus PV generation from the Zappi to...
