Activate parallel control
The parallel control function offers the opportunity for several chargers to cooperate in order
to charge the battery with a higher charging current and thereby faster. This can be useful in
situations where a fast charge of the battery is essential. This function is designed to primarily
work with chargers of the same type for example 48/80. See
5.5.13 CAN
for more information.
Note that one of the chargers has to act as a master and control the other chargers (slaves) in
the cluster. How the charging process will be carried out will be determined entirely by the
master and the slaves will comply with the charging parameters set by the master. The
different chargers in the cluster are connected to each other via the CAN connections on the
I/O Board, CAN High to CAN High and so forth. See
Appendix 1 I/O Board connections
for more
information regarding which PINs to use. Here follows a tutorial for how to activate parallel
control.
1.
While in the service menu put the marker on
CAN
and press
OK
. The following menu
