Thanks for the input but I am specifically referring to DCFC charging and am familiar with the rate drop off.
MORE specifically ABB Model Terra 53cj series as described above.
Thought I had it solved :
After 5 tries managed to get 41kW rate from 59% to 22kW rate at 68% (15 minutes 30 seconds it cut out c/w com error) Tried 15 different combo's of reset DCFC machine and unlock/lock doors etc ( doors opening definitely caused stoppage) with a result of 7kWh delivered .

Stopped by Hyundai, says many complaints filed- corp says car is ok its the machine.
Am waiting for call back from BC Hydro tecks to discuss how I manged to get it to work (once)
Went to this location using EFA manufactured model# EVQC45 dual (old faithful as I call it) and it worked perfectly, so car ok:

The Rate started at 41kW and dropped to 25kW SOC 66% to 80% (I have set the level of max charge DC to this)
My hope is to ensure that the "rom or firmware" fix is done as quick as possible on all of these models.
