OBD Data

[tsedge]

@electricsidecar I appreciate your work to support the MG4. Having a good choice of solutions provides the best for everyone.

For LFP 94% is nothing to worry about, 95% is typical after a year's average driving but there are variations between packs and driving conditions / styles etc...

Agreed, although we had other "signals" that suggests we should keep a close eye on it. Including a sudden drop in overall pack voltage (and reported soc) while the vehicle was off (and without a significant change in external temperature).

I'm quite interested in logging the cell pack voltages and temps to see if we can detect any signals of an early failure. This is one of the things you cannot do via API for example

Pack voltage last 30 days from the API:

and temperature:

I'm aiming for Electric Sidecar to bring value to vehicle owners who want minimal configuration paired with maximum understanding of their vehicle. I see this as a bit of a spectrum on which there exist many products similar to Home Assistant and Electric Sidecar.

Makes sense. The value add is making it easier to access.

There are OBD readers with internet connectivity actually!

Neat.

Totally understandable! Trip routing is a difficult feature to get right at global scale. Electric Sidecar takes an intentionally different approach and provides a "fog of war" map instead to encourage exploration.

I've no idea what that means.

I just need to know how to get where I want to go and the best way there, plus any useful info en-route.

Using Waze for that but my wireless CarPlay is crud.

 

[electricsidecar]

I've no idea what that means.

Turning on history mode in CarPlay covers the map in a cloud layer that gets permanently erased as you travel around. It's kind of the opposite of a trip navigation feature haha.

OK what android aplication you use for MG4

Do you get detail similar to these 2 images ?

If so how do you use it? E.g. is there some particular Imbalance value that is bad or are you looking for differences between the groups, or simply looking for changes over time?

I'm still not understanding. It adds a cloud layer that is erased?

Think I need to see it in operation. My CarPlay has no such "history mode" option to turn on or off.

 

[siteguru]

Is that a Google Maps thing or an Apple Maps thing? (I doubt it's a CarPlay thing).

 

[electricsidecar]

It’s an Electric Sidecar thing It’s part of the trip logging feature.

Thanks to @nanomad's guidance I've got SAIC accounts working in Electric Sidecar's development branch:

If you'd like to give this account support a spin and provide feedback, shoot me a DM and I can add you to the TestFlight.

Some other updates:

• @nanomad's added a bunch of extended OBD PIDs: MG-MG4/signalsets/v3/default.json at main · ElectricSidecar/MG-MG4
• MG4 has its own vehicle symbol now.
• I've started capturing some of the more common MG4 issues in the Electric Sidecar issue tracker: Issues · ElectricSidecar/MG-MG4

Outstanding work and app

 

[sparc00]

Just found this thread from a Google search because one of the Electric Sidecar users owns an MG MG4 and was hoping to connect their OBD to the app. If anyone on this forum would be interested in helping test the OBD scanning functionality, I'm happy to provide promo codes for Electric Sidecar — Electric Sidecar - Automotive assistant for iOS for more details. I don't have access to any MG vehicles in the states so I'm hoping someone can verify the PIDs I'll be adding to GitHub - ElectricSidecar/MG-MG4

Hey electricsidecar, I would be interested to test out and give feedback. I use vGate vLinker MC+ for ODB2 connection and I have both iOS and Android devices (if I am not mistaken app is strickly iOS currently though)

 

[fnegroni]

I’d be interested too. I have an OBDlink MX+ and iOS device.

@electricsidecar for some reason I cannot reply your message, anything I type gets an error as

Hi,

Do you know if it is possible to have mean consumption in kWk/100hm on OBD Scanner, or another app which can record data ? I would like do make some measurement with mean consumption (kWh/100km), distance (km) SOC (%) during a trip.

 

[EVentropy]

Thanks, I use my Vlink OBD with Car Scanner and ABRP and love the accuracy but hate the alarm issue. I will try disconnecting BT before locking. I also have a Carlinkit unit now so will be trying using that instead as it powers off when the car is locked.

So, you are getting meaningful results from car scanner? My CS data is bollocks.
ie SOC, SOH, and cell delta cell voltages....etc . I have ABRP, but as a stand alone not any better than SAIC's center console data.

Vlink OBD? Vgate Vlinker FD+, FS.....which one? So many out there and a LOT dont work for MG4 SR.
I have both android and iphone.
Cheers.

Finally found Obd2 Vgate that works properly, but temporary MG4 profile in CarScanner app makes lots of annoying stuff during setup

Is that Icar pro 4 Vgate V2.2?
Thanks

 

[EVentropy]

The 64kWh NMC pack has a usable capacity of 61.7kWh ... that's 2.3kWh of buffer, which is what degrades first hence SOH can remain at or near "100%" for longer. That's also partly why LFP packs seem to degrade more in the first year, as there is very little buffer.

That is reasonable.
Also my experience with SOH on other monitors has been that they essentially do it through coulomb counting which needs a couple of 100% charges to <10%, or preferably 0% to calibrate. Otherwise they drift away from being accurate.

For LFP 94% is nothing to worry about, 95% is typical after a year's average driving but there are variations between packs and driving conditions / styles etc...

My almost 2 years MG4 SE SR (so LFP model) is at 92% SoH..

Can ODB dongle be read by 2 different app running on the same device? What I'm thinking is to use ABRP and car scanner at the same time..

No
