It is clear that you do not have the facility to charge your car via A/C charging ( wall box /public post or Granny ) with the doors unlocked.
There is a update that WILL permit this facility, but it was not a full feature of the Comfort 2 update.
To answer your direct question, in the current state of the software in your car, if you are sitting in the car with it already plugged into a A/C charger, when sat in the drivers seat, locked the doors from the switch on the drivers door panel.
As soon as you do this, the car should commence charging.
But remember, as soon as you unlock the car, or exit the car, the charging will stop !.
Charging unlocked/locked update for ZSEV
The ZSEV has always supported unlocked charging on CCS (rapid chargers) and in 2020 a software update was released to add this function to charging on type 2 (6.6 kWh fast chargers). You are less likely to want to sit in your car for this slower charging, although it can still be occasionally useful. This is a side update to the BMS update: specifically to the EVCC module of the car. Once this is installed, the car will charge both locked or unlocked.
To stop the charge after the update, lock the car, then simply unlock with the key fob whilst at the front of the car. You will hear the car unlock the charge lead locking pin will disengage, and you can then remove the lead. If you do not unplug the lead, it will re-engage the lock and resume charging about 15 seconds later.
Please take note of bullet point 8 below !....
Comfort 2 update - info from MG website
( NB - if you purchased your car after mid June 2020, the car should have had the Comfort 2 update installed and therefore bongs etc dealt with. If you are being asked to pay for this update in 2021 as a new purchaser, you should definitely query this.)
During the lifespan of a vehicle model, various changes can be made to interior trim, exterior cosmetics or system functions to ensure that it features cutting edge technology and remains attractive to potential buyers.
MG ZS EV models manufactured after mid-June 2020, will have a newly developed 2nd generation of Comfort System Operation installed on the car. This is now available for customers who wish to benefit from these later updates on earlier build models.
Whilst all the below features involve software changes to key components on your vehicle, the updated software is not available to cars with 1st Generation software as a ‘warranty upgrade’. MG’s warranty is there to cover the cost of repair or replacement of a failed part due to a manufacturing defect, and not for updates/upgrades, and will therefore be chargeable. Please speak to your MG dealer to find out associated charges for this update.
This new 2nd generation of Comfort System Operation includes changes to:
- Faster system self-check when powering ‘ON’
- Infotainment volume maintains and restarts at previous volume setting after powering ON/OFF
- Auto High Beam system disable option available in menu settings
- General warning chime quality improvements and reduced volume
- Warning chimes reduced for MG Pilot and Key Reminder
- Vehicle temperature and temperature alarm featured in the instrument display
- Vehicle range always on display in instrument pack
- Vehicle can be unlocked during A/C charging, when re-locked charging automatically resumes.
