3.6.2
Socket, Type 2
The manufacturer can deliver the EVSE with a socket for an AC charge cable Type 2.
For the current rating specifications, refer to section
.

Power allocation strategy
The charger is equipped with an AC Type-2 socket. The AC outlet acts independently
from the DC outlets, however all outlets are affected by the AC grid current
limitation. DC charging has priority over AC charging in the power budget
allocation. When an EV is plugged into the AC socket, the charger looks at the actual
power usage of the EVs charging DC, and the residual power is allocated to the AC
outlet. The residual power available depends on the site limitations, such as on the
AC grid fuse that has been used.
Maximum station power: specified by the AC input limit
Remaining power = Maximum station power – DC charging power
The AC charging session can start when the remaining power is more than 50% of
the maximum output of the AC socket: for the 22kW outlet, the remaining power
must be more than 11 kW (> 30 A @ 400 V).
If the input current can not be more than (3x) 100A, the charge session on the 22kW
outlet can start the charge session when the remaining power is more than 16,5 kW
(> 43 A @ 400 V).
The message “Waiting for power to be available” is shown on the screen when the
remaining power is less than the limits given above. The charge session is kept on
idle until more power becomes available.

External residual-current device
The manufacturer does not supply an external residual-current device. If an external
residual-current device is required because of local rules, this section helps you to
select the correct device.
Situation: the local rules require an immunity for short current peaks over PE
during the EV charging process
At the start of the EV charge cycle, a relay switches and engages the AC input power
to the power modules. Incidental current peaks can occur.
A combination of these factors is the source of these current peaks:
