Other Load Sharing Behaviors

• Available current is redistributed equally
among all connected vehicles whenever a
new vehicle is plugged or unplugged from
the network.
• During steady-state operation, the load
sharing network toggles available current
to each vehicle in 2A increments, every
minute, to asses vehicle need. When a
battery approaches full charge, the power
consumption will taper until charging is
complete. If the master unit detects that a
vehicle is no longer using all of its
available current, it will reduce the current
allocated to that vehicle
• A slave Wall Connector will not charge if
communication is lost with the master
Wall Connector.
• In rare cases, firmware updates on a
master Wall Connector will interrupt
charging on the slave Wall Connector(s).
This is normal behavior, and charging
should resume once the firmware update
is complete (15 minutes).
