3.4.3
Charge Over-Current Protection
Charge Over-Current protection disconnects charger contactor or disables charger itself if pin function
"Charger enable" is activated whenever the measured charge current is above the threshold set by
the corresponding "Activation Threshold” parameter value, thus preventing the high currents during
regenerative processes from potentially damaging the battery cells.
3.4.4
Discharge Over-Current Protection
Discharge Over-Current protection is activated if the measured discharge current is above the thresh-
old set by the corresponding ”Activation Threshold" parameter value, thus preventing the battery
from being discharged at a rate that is higher than specified by the battery cell manufacturer.
3.4.5
External Over-Temperature Protection
External Over-Temperature protection prevents the battery from being operated when the tempera-
ture measured by one of the external temperature sensors is above "Activation threshold" parameter
value, which may indicate an unexpected heat development somewhere in the battery.
3.4.6
External Under-Temperature Protection
External Under-Temperature protection prevents the battery from being operated when the temper-
ature measured by one of the external temperature sensors is below "Activation threshold" parameter
value, which indicates that environment is too cold for battery exploitation.
3.4.7
Internal Over-Temperature Protection
Internal Over-Temperature protection prevents the device from being operated under high tem-
perature, which could build-up if heat dissipation is not performed well due to unexpected heat
development inside device. Protection is activated when value of measured internal temperature is
above "Activation Threshold" parameter value.

Configuration
Settings that regulate the behavior of the protections can be found in the Configuration page
→
Protections tab and consists of six sets of parameters for each different protection type. Each set
contains five of the following parameters:
•
Enable/Disable protection;
•
Enable deactivation
•
Activation Threshold;
•
Deactivation Threshold;
•
Activation Delay;
•
Deactivation Delay.
All thresholds and delays are configured independently for each protection. All protections are
enabled by default, but can be disabled individually if necessary."Activation Threshold" and "De-
activation Threshold" parameters, allow to create hysteresis between activation and deactivation
values. BMS is forced to tolerate activation condition for as long as corresponding "Activation
Delay" parameter value before activating the protection. Likewise, the deactivation condition has
