22kW AC charging beyond 11kW.Is it normal?

[Fly4ever]

Charging today morning at a 22kW AC charger I noticed that occasionally the charging speed went slightly beyond 11kW at 11.020Watts.It stayed there for several minutes then returned where most of the time stabilise, hovering around 10.950~10.990Watts.Is it normal to exceed 11kW even for this slightest amount or it might declare a possible issue ready to be unfold?

this is no problem

watts = volts * amps

voltage varies and can go high or low versus ideal - current flow is what matters and 48 amps @ 250v is more than 11 kw - this is true even for euro where it’s 3 phase with each phase being 16 amps for 48 amps total

what you are seeing is nominal grid voltage variations pushing watts around during the charging session
