Kg: 8
Control Logic and Protection Limit
The inverter, if applicable, must be set with the below restrictions in addition to the BMS
control logic.
MAX CURRENT WITH BUS BAR
*
Please refer to the above table according to the number of clusters and parallels applicable to the system.
1.
The charge current will be limited to zero Amps when the single module voltage has been reached 56.8V.
2.
The discharge current will be limited to zero Amps when the single module voltage has been discharged to 50.4V.
3.
The battery system will communicate with the inverter to limit the current.
4.
Each Battery Module will be protected by the same logic separately as per single module protection concept.
5.
If some modules, individually, reach any fault status, the single module will protect and disconnect from
the system in less than 3 seconds.
6.
The current limit must be adjusted according to the real active batteries in system to restore the normal function.
7.
If the cluster is not balanced, the current limitation set from the HUB to the inverter will be sent to manage
the rest of active modules and clusters. At the same time, the imbalanced modules or cluster will equalize
in standby mode and will reconnect once in the normal range.
8.
If more than two batteries in one cluster are in protection mode, the entire cluster will protect by shutting down.
9.
If there are more than two clusters in protection mode, the full system will be protected.
10.
The battery sends information to the inverter to limit the charge/discharge current to zero Amps if the
battery is detecting an over current.
11.
The protection built into the BMS will automatically disconnect the battery when it detects excess values.
The BMS will attempt to reconnect up to three times to check if the excess values have returned to within
the permitted range. After three attempts to reconnect, the BMS will not attempt any further
reconnections. The Battery Module can be restarted using the module power switch and run button,
however, if the external fault condition which caused the Battery Module to shut down is not rectified, the
battery will continue to enter the shutdown mode.
12.
If the current of one cluster is larger than the current limit, the battery system will send a warning in
accordance with the single module BMS logic.
