7.4 Limon™ BMS Software Current 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 values before saving all settings.

Table.7.4.1: Current Settings Screen Elements Descriptions

Element No.	Description	Setting Options
M4	Selection tab for Settings.
T4	Selection tab for Current Settings.
S46	Discharge Over Current Warning	Triggers a warning event before reaching discharge over current protection point.
S47	Discharge Over Current Protection (1st)	First limit for maximum allowed discharge current. This value may set to lower than 2nd point with higher delay time. Slow acting current limit.
S48	Discharge Over Current Protection Delay (1st)	Delay time before 1st discharge over current protection event.
S49	Discharge Over Current Protection (2nd)	Second limit for maximum allowed discharge current. This value may set to higher than 1st point with lower delay time. Fast acting current limit.
S50	Discharge Over Current Protection Delay (2nd)	Delay time before 2nd discharge over current protection event.
S51	Charge Over Current Warning	Triggers a warning event before reaching charge over current protection point.
S52	Charge Over Current Protection	Maximum allowed charge current.
S53	Charge Over Current Protection Delay	Delay time before charge over current protection event.
S54	Maksimum Allowed Peak Current	Very fast acting discharge current limit. Assume this value as the highest discharge current threshold without any delay time.
S55	Current Sense Input Channel No 1 Coefficent	Voltage to Current Coefficent for channel 1 input (sensor output)
S56	Current Sense Input Channel No 1 Offset	Negative or posite current offset can be set when needed.
S57	Current Sense Input Channel No 2 Coefficent	Voltage to Current Coefficent for channel 2 input (sensor output)
S58	Current Sense Input Channel No 2 Offset	Negative or posite current offset can be set when needed.
S59	Current Sense Input Channel 2 Low current limit	If two channel current sensor type used in the system, low current channel current value can be set. Otherwise this value is not effective to current sensing.
S60	Self Discharge Power	Battery packs self discharge power. This value is adding to energy calculations for correction of quiescent power.
S61	Curren sensor configuration and pinout setting	You can select various type of current sensor and channel configuration. For best measurement result select correct type. NO SENSOR INSTALLED: No sensor was installed to battery pack. CH#1(H) or CH#2(H): Select when one channel sensor is used. Set one or two channel's coefficient. If any channel can't use, leave it floating, set coefficient to zero (0) and set only used channel's coefficient. CH#1(H) and CH#2(L): Select when two channel sensor is used. Set every channel's coefficient for both low and high current side. Measurement channel is switch internally according to settings.
S62	Precharge current limit	Precharge current must be lower than precharge current threshold at the end of the precharge time. Otherwise precharge current is not sufficient for the load.
S63	Precharge time	Precharge time before discharge power path is switching to ON.
S64	Precharge Strategy	You can enable precharge process and precharge conditions. PCHG Function Disabled: No precharge event. System will switch ON the DCHG path without precharge ptogress. PCHG Time Only: System will apply precharge current along PCHG time before DCHG path is switching ON. PCHG Time and Current Limit: System will apply precharge current along PCHG time and checks PCHG path current before DCHG path is switching ON.
B1	Read all setting from BMS memory.	You must read all the settings from BMS before making changes on the any settings.
B2	Save all setting to BMS memory.	You must save all the settings after making changes on the any settings.
B3	Import setting from setting file on your local computer.	You can import settings which exported before.
B4	Export setting to setting file on your local computer.	You can export settings after read all event.
B5	Restart the BMS board	Some changes may active after a software restart event.
B6	Turn BMS into factory settings.	This event cannot be undone.
