Concurrent Power Allocation; Dynamic Allocation 'First In First Served - ABB InCharge Terra 184 Manual

3.8.2

Concurrent power allocation

When the EVSE is configured for concurrent power allocation, it can serve two EVs
at a time with DC fast charging.
In this configuration the EV charging power delivered by each outlet is up to half of
the maximum power available to the EVSE, a maximum of half of the rated power
output of the station. Effectively the maximum power output can be less than the
rated power output because of power constraints. For example, the power output
can be permanently limited due to site current or power constraints, or temporarily
limited by power management systems.
The EVSE can do two DC charging sessions at the same time. When one EV is
connected to the EVSE, it will receive up to half of the maximum power available
to the EVSE. When a second EV is connected to the EVSE, this second EV will also
receive up to half of the maximum power available to the EVSE. When one of the
charge sessions ends, this will not change the maximum amount of power that is
delivered to the other charge session.
3.8.3

Dynamic allocation 'First In First Served'

When the EVSE is configured for First In First Served (FIFO) power allocation, it can
serve two EVs at a time with DC fast charging.
In this configuration the EV charging power can reach up to the maximum power
available to the EVSE, up to the rated power output of the station. Effectively
the maximum power output can be less than the rated power output because of
power constraints. For example, the power output can be permanently limited due
to site current or power constraints, or temporarily limited by power management
systems.
Up to two DC charge session can be performed at a time. When one EV is connected
to the EVSE, it will receive up to the maximum power available to the EVSE. When
