7.2 Limon™ BMS Software Cell Settings

Battery management system's most important part is the settings. User must set the correct parameters of the system to achieve no errors.

Danger

Always double check your settings before saving all settings.

Table.7.2.1: Cell Settings Screen Elements Descriptions

No. Description Setting Options
T2 Selection tab for Cell settings.
M4 Selection tab for Settings.
S14 Over Cell Alarm Voltage Triggers a warning event before reaching cell over voltage protection point.
S15 Over Cell Protection Voltage Protection limit for any cell's voltage.
S16 Over Voltage Protection Delay Time Delay time before cell protection event.
S17 Over Voltage Protection Release Voltage Release voltage value when cell over voltage event has been triggered
S18 Under Cell Alarm Voltage Triggers a warning event before reaching under cell voltage protection point.
S19 Under Cell Protection Voltage Protection limit for any cell's voltage.
S20 Under Cell Protection Delay Time Delay time before cell protection event.
S21 Under Cell Protection Release Voltage Release voltage value when cell under voltage event has been triggered
S22 Minimum cell voltage threshold to start balance progress Any balancing cell value must be higher than this threshold to apply balancing current
S23 Cell balance start delta voltage Any balancing cell value must be higher than this threshold to apply balancing current
S24 Cell Balance Stop Delta Voltage Balancing current has apply to cell until reaching desired cell delta voltage after starting balance progress.
S25 Imbalanced maximum cell delta voltage This value is critical value of delta between any cells in the system. Any value higher than this threshold will trigger full protection event.
S26 Maximum Simultaneously Balancing Cell Count Number of cells to apply simultaneously balancing current. Higher value may require extra cooling elements.
S27 Cell Balancing Method:

Balance Restricted: Balance Operation Disabled
While Charging: Balance Operation Only While Charging
While Discharging: Balance Operation Only While Discharging
When Not Idle: Balance Operation Only While No Charging or Discharging
Always: Balance Operation Always ON
While charging option may selected for best balancing progress.
Options: Balance Restricted, While Charging, While Discharging, When Not Idle, Always
S28 Balance Power Duty Cycle Selection Between 10% - %100 Applying full balancing current is not a good option for sustainable system response. Select a mean value for optimum balancing current.
Options: 10, 20, 30, 40, 50, 60, 70, 80, 90, 100
