Power Sharing - Flo CoRe+ MAX Installation Manual

4. Power Sharing

The CoRe+ MAX can be configured in standard or power sharing mode. With the integrated
power sharing capability of the CoRe+ MAX, a maximum of four charging stations sharing
the same 100 A circuit for a total load of 80 A can be connected in parallel to the same
branch circuit. Here are some characteristics of power sharing mode:
 The charging stations connected in parallel to the same branch circuit must all be
CoRe+ MAX models (the specific model identification can be found on the unit
label).
 To allow for dynamic current sharing, a site controller application must be
installed and properly configured by FLO.
 Without a site controller installed or in operation, or in the event of a loss of
communication, each CoRe+ MAX limits its output to 6 A when set in power
sharing mode.
 The site controller will then ensure that the maximum available current is shared
optimally among the charging stations (between 6 A and 80 A for each station)
while ensuring that the maximum circuit capacity (80 A in the case of a circuit
protected by a 100 A breaker) is never exceeded.
 For safety reasons, each CoRe+ MAX charging station will immediately interrupt
an ongoing charging session when the connected EV draws more than the
specified amperage limit at any time. To resume charging, the user must restart
the usage session process from the beginning.
 The site controller is provided by FLO as part of its Global Management Service
(GMS).
 The communication between the site controller and the charging station is done
through a wireless meshed Zigbee network. A communication gateway must
therefore be installed. Refer to the Communication Gateway Installation Guide
provided by FLO for further details.
The maximum number of charging stations sharing the same 100 A circuit (for a total load of
80 A) is 4.
