I recently came to buy a three phase cable for my early MG4 Trophy (which can do 11kW!), and was initially confused by all the different options of cables out there, and the restrictions on speed when combined with the various AC charging points as well!
So it's prompted me to create the...
I always park my car in my garage, therefore my charger is in my garage.
Having the charger there is also likely to prolong the life of the charger as it won't be exposed to the elements as it would be outside!
It's not too old (11 months), as it has the "large button" air con screen instead of the earlier one with the tiny circles. Most settings should be the same though either way.
If you're on an earlier version of the infotainment system, there are two files on the USB that you need to delete before starting the update:
VN.txt and File_verification
If you delete those from the root of the USB and try it again that may resolve it for you.
So, it seems to put me in Berlin if I have my phone connected by Bluetooth (nothing else, just standard Bluetooth connection). If I switch off my phone Bluetooth, it correctly puts me where I actually am!
I think the main takeaway is there's not a single figure such as "regenerative braking recovers 90% of the energy", or anything like that, as there are a myriad of factors at work.
Suffice to say the answer is, "it's complicated", and enjoy the drive. ?
They measured the energy recovered by calculating what was put back into the battery, vs the kinetic energy "lost" due to braking of the vehicle:
They were interested in the efficiency, and not specifically in all the ways that the efficiency can be reduced... but there are other papers on...
If everything is "normal" and the HV battery isn't really low, then the 12v battery should also be OK as well, as the vehicle should automatically keep it charged when powered off... from manual:
So as said there are a lot of factors that effect regeneration performance. One of the major ones is speed at which you start braking - lower speeds regenerate much less (and indeed very slow speeds aren't very efficient at all - they do slow the car down well, but they don't recover much...
So yeah, that option is there (UK R59 + "other updates" done by dealer last week)
Only thing is, when I tried it, it seemed to think I was in Berlin (even though normal satnav was correct). Will switch off and try again tomorrow... ?
Yes - the issue I imagine that makes then pause with OTA, is you have to have a pretty robust system for carrying out end user updates.
i.e. it has to be able to cope with any possible failures and have a clear path to be able to rollback if necessary, otherwise you can end up with "bricked"...
Don't forget also that the regenerative aspect is not just a factor of the mechanics of the motor/generator, other things come into play too, such as the current temperature of the battery and the current state of charge of the battery, both of which will affect how much of the recovered energy...
I don't think "over the air" (OTA) updates have been activated/permitted in many countries yet, so the only way to get updates is via a dealer. They're only likely to do an update if you complain about a specific issue that an update might address.
The reason they suggest that is the final connection (being the negative of the donor to the negative of the "disabled" vehicle), may cause a spark when you connect it.
Sometimes 12v batteries can vent flammable hydrogen gas, so it's to avoid the possibility of the spark igniting them...
The iSmart app really does give some interesting temperature readings sometimes.
I really hope it's not accurate, as if it is, it probably means my garage is on fire... ? ?
