Video: EVSE with grid monitoring vs 2000W water kettle. Will

[vtechtuning]

A test of Grid Monitoring used in Accelev https://www.facebook.com/EVSEChargerAccelev/

Car loads with a max speed of 16A, as the breaker is 16A. Then I start a water kettle (2000W) - once with Grid Monitoring at charger is on the second time - off. I restart charging, as charger needs 1 minute to go back to full speed after switching off the kettle.
The charger detects load (water kettle) and immediately slows down charging. Without that function (with cheap Chinese chargers like Duosida or Zencar) - breakers will be switched off because of grid overload.
Sorry for a shitty video, done with an old iPhone.

Very interesting, thanks for sharing. I don't understand how that works at all!

Does the standard charger that comes with the car have that funtionality too?

Of course, a standard charger does not have such functionality.
That charger uses SOP calculation (https://evtun.com/chargers/sop-health-of-your-home-grid.html) to find a proper grid monitoring/power reducement scheme.
As I use it for one year (with some upgrades they send) - this works.

But the Ratio 10/6A charger "brick" does offer this functionality and refuses to attempt to charge at 10A if the grid does not support it.
