Balancing; Discharge - Bicker BP-LFP-1375 Operating And Safety Instructions Manual

BP-LFP-1375
Note:
Under extreme conditions e.g. at particularly low or high temperatures, the charging and
discharging behavior in conjunction with your application should be checked. The cell
characteristic leads to a different voltage behavior of the cells.

4.3. Balancing

The BMS balances the cells during and after charging process. The required balancing
times are determined automatically. Optionally, a discharge-charge cycle, in which the
cell capacities are newly determined, is required for the error-free determination of indi-
vidual cell capacities.
Abbreviation
Min RSOC for Balancing
Min Start Balance Delta

4.4 Discharge

The BMS switches off the output voltage when the final discharge voltage is reached.
Protective functions of temporary, reversible or permanent faults and short-circuit
detection are not affected by this!
After complete discharge, charge the battery system soon (within 7 days) to avoid a
deep discharge.
Successful completion of discharge process:
When the discharge end voltage is reached, the flags FD and TD are set.

Description / Condition
Balancing in idle state only
takes place when charge state
is above the limit value.
If the cell voltage difference in
idle state is above the limit value,
the required balancing time is
determined.
