3.1.2 Value for limitation of the power grid
A key value for the load management system is the total maximum available current (amps) of the power
grid. This value represents the maximum power which can be supplied from the grid due to wiring and fuses.
Additionally the maximum total current can be reduced in dependence of time and day.
Example:
The total maximum available current of the power supply line is 200 amps. Between 8 o'clock pm and 6
o'clock am there is no reduction. From 6 o'clock am till 8 o'clock pm there is a restriction to reduce the maxi-
mum total current down to 120 amps.
Splitting between Mode 3 charging and ISO charging
The maximum total current for charging vehicles using Mode 3 communication or ISO communication can be
split into two sections. For both groups of vehicles thus the available total current is reserved.
The specified limit is dynamic, so vehicles with a Mode 3 communication can temporarily use free quota from
the ISO range as long as there are free capacities. Vice versa this is not possible.
Example:
80 amps shall be reserved for Mode 3 charging.
120 amps shall be reserved for ISO charging.
