Hi folks,

I am just highlighting this thread, please contribute your votes to this thread on what you'd like us to cover in future podcasts, thank you.

It'd be great to have some kind of index to show what's covered in each cast. For example, I'd love to see a podcast covering the old chestnut, LKA. I'm sure this has been covered already (briefly touched on the latest cast from June 24, but it turned out to refer to the LKA on a Hyundai )

Just bumping this back up the forum list - please continue to vote and tell us what you would like to see.

I've made the thread sticky for now, to save you having to keep bumping it.

It would be great to see a discussion on best practice for realising a long life for the traction battery, particularly the equalisation charge and any nuanices between the different battery chemistries. LFP has such a flat SoC/voltage curve it needs to be charged to 100% for it to perform an equalisation charge, while the NMC chemstry is not as flat and going above 80% starts to go into greater degradation territory... so is the BMS able to do an equalisation charge at a "percentage limited setting" of the NMC batteries or does it need to charge to 100%?

 

[MrSnuffles]

... like this:NMC balancing at 80% SoC

I second that, and in particular I'd like some guidance about when to use battery heating.

It might be worth getting an expert as a guest speaker for that discussion.

 

[Rolfe]

If Euan McTurk could be induced to do it, that would be a great catch.

 

[HazardLights]

Sorry if this has been covered but I have a memory like a sieve... how about an update from MG UK on when OTA updates will be coming to the UK as the current situation isn't great for brand image?

 

[AlexC]

Yes, OTA & s/w updates in general need to be raised. I will try reaching out to get feedback.

 

[MG4EVLawyer]

Yes, the topic of updates would be fantastic and the reasons for the seeming reluctance of Dealers to do them. Sisiak(?) on YouTube has done an interesting video on MG4 R59 update

100% We need to feedback to MG UK perhaps individually and via dealers that much more needs to be done to enable updates, changelogs etc.

There seems to be a problem when trying to look at the MGs EV Podcasts. It comes up with:

Ok, I have notified Stuart, thanks.

I think now the weather is getting colder it would be good to cover battery heating. What benefit is it, when should we do it, and is it worth the electricity it consumes? Is it the same for LFP and NMC, or are there different protocols?

This, including the question of whether the logic for battery heating is the same for short versus long journeys and also whether it makes sense from a battery life point of view given that low temperatures have long lasting effects on battery life.

In an ideal world Dr. Jeff Dahn would come on and share his expertise on batteries.

 

[AlexC]

Yea and add charging in there. Why for example does OPD sometimes fail to enable on 90% SOC with spurious low kinetic energy warning.

 

[siteguru]

I think charging was covered in one of the recent podcasts.

Yes, although we didn't cover OPD (I don't have it on my car).

I will see if we have any more information on these issues for the next podcast. We will cover them only if have we something useful to say in answer.
