Balancing is starting, when voltage of the most charged battery cell is higher, than the value of Balancing voltage (parameter P17 in ProTool). Balancing is running even after the deactivation of the BMS 16i (Switch [K5] is OFF). Balancing is finished, when all battery cells are balanced / charged to value of Charged cell voltage (parameter P18 in ProTool). - Page 24 P22: Discharge fuse Controlling of maximum discharging current. In case, that discharging current is over the limit, then the overcurrent error is broadcasted. In case, that the value is 0, then the discharge fuse is switched off. P23: Charge efficiency Charge efficiency is the rate, which compares the current given to the battery and current, which could be taken from the battery.
- Page 25 Logging mode In case that the parameter is adjusted to “OFF”, then the logging of the critical statuses of BMS 16i is switched off. In case that the parameter is adjusted to “Critical states”, then the logging of the critical statuses of BMS 16i is switched on and logging is running.
