Charging Model:

Charge Curve - Insufficient data yet to be able to provide this as the car is brand new

Hi, my first post on this forum, I've been quietly following this app for some time but haven't until now actually had use for it. I really think the world needs a powerful tool like this for making the adoption of EV's happen. Keep up the good work!

I got a brand new MG5 EV on Christmas Eve this year 🙂 Since then I've been scouring the internet and fiddling with my OBD2 dongle.

I discovered a lot of work done by the guys over at https://discourse.mymgzsev.com/ for getting the necessary information out for an MG ZS EV and as the MG5 is very similar I've managed to get most of the information to work (with the exception of ambient temperature and odometer readings). The responses I'm getting back from the PID's are occasionally blank so I've had to take samples over time and then used the MAX function to filter out blank values. It's pretty stable but sometimes 0 values still creep through, strangely the Battery Temperature readings are completely fine. I've done a few test drives and recorded the values being shown on the driver display unit and the values coming into torque and they now match up.

Live charging information is going to be tricky with both the ZS and the MG5 as the car alarm is set off if the OBD2 data is read while the car is locked. However the car does report it's Max Charge rate all the time so this may be the way to get this information.

The data I'm currently able to capture from the car is;

• State of Health
• State of Change
• HV Battery Voltage
• HV Battery Amps
• HV Battery Coolant Temp
• Maximum Charge Rate
• Is Charging

Then with GPS data from the phone I believe this is everything needed to do the live data, most of this should work with the ZS as well but someone with a ZS would need to test.

I have my torque app uploading data to the torque web server at the moment to start building up some data so when I have more info, I'll update you with some basic profiles.

I think I have a much better way of handling the blank responses that give very clean data. I'll post when I have done some more testing

Here's an updated version of the PID's, managed to trick Torque into only updating the values when a none blank response is returned.

Working really well now and the data looks good, compared against what my driver display unit says.

Here's the data I have collected so far

And a minor change to the PID file, the SoC was incorrect

Seem to have most of the data required now for an initial model, only got the low end of the battery to capture now.

Wow! This is some seriously great data to work from.  I've put together an alpha model based on this data, please go play with it on the site and see if it matches up with your experience.

We can add Torque Live Data support very easily.  Is the PID list your work? If so, would you like us to host the list, or would you prefer to post it on Github (or some other public repository) we can point the download link to?

@Jason (ABRP)the mg5 EV is not visible in the list of selectable cars.

Ah, that's on me, I forgot to set it to visible once I finished modelling and testing it.  It's available now!

Hi, those values seem really good for the MG5.

I had a quick play comparing a journey from Edinburgh to London with an MG5, Zoe 50, Peugeot e208 and Tesla 3 LR 2021.

I did a quick post about it on SpeakEV here:

https://www.speakev.com/threads/mg5-charging-profile.156162/#post-2951764

It's a great result for the MG5 being faster than the Zoe and the e208 - are these sorts of charging speeds consistently available?
