For a long time, in the domestic energy storage market, active
balancing of battery cells has been difficult to promote, and
balancing solutions for battery packs and battery clusters seem to
be even more difficult to find a place.
Due to the differences in overall energy, number of battery cells,
working current, etc. among large storage, industrial and
commercial storage, and household storage,
large storage has relatively higher requirements for balancing
capabilities than industrial and commercial storage and household
storage. However, whether it is large storage, household storage or
industrial and commercial storage,
they will face scenarios with high requirements for the balancing
capabilities of energy storage systems. When BMS active balancing
is difficult to meet the needs of the following three scenarios,
the value of adding an additional DC/DC module solution can be
highlighted. According to Gaogong Energy Storage Research,
there are mainly three scenarios with high requirements for the
balancing capabilities of battery packs and battery clusters:
First,
after the energy storage system has been running for many years,
there is a large discreteness; second, the original battery pack
itself has poor consistency,
or is used for cascade battery energy storage; third, some battery
packs in the energy storage system are damaged and need to be
replaced and new and old batteries mixed.

Wiring Diagram
EK-16S2EB supports cascading use, and at least one battery between
every two equalizers is the "common end of energy exchange". The
following uses the 32S as an example to describe how to install and
connect cables:
Notice:
1.When used in cascade, there is at least one "energy exchange
commonend" between every two equalizers. When welding, please note
whetherthe connection here is correct.
2.During cascading use, please check whether the wiring is
wrongrepeatedly.lf it cannot be used after connection, please
contactafter-sales personnel to consult the corresponding cascade
diagram.
