9 +* Capacity – nominal capacity of cells, Ah;
10 +* Resistance – nominal (maximum) internal resistance of the cell, Ohm;
11 +* Relax time (after charging) – a relaxation time after charging, second;
12 +* Relax time (atfer discharging) – the relaxation time after discharging, second;
13 +* Cycles – a number of charge-discharge cycles;
14 +* Reset battery cycles – a command to reset charge-discharge cycles;
15 +* Reset cell parameters (SOC, capacity, resistance) – a command to reset cells state of charge, capacity, and resistance.
16 +
17 +The values “Capacity”, “Resistance”, “Cycles” are used to calculate the SOC of cells and battery.
18 +
19 +The values of “Relax time” are used to determine the state of the battery. If the battery is in a state of relaxation, the system recalculates the voltage on the cells to the state of charge of the battery.
20 +
21 +The “Reset cell parameters” command is used for starting-up and adjustment of battery.

24 +
25 +The BMS Main 2.x board calculates the state of charge of the battery (SOC) using two algorithms:
26 +
27 +* by open circuit voltage;
28 +* by current and voltage.
29 +
30 +It is recommended to use the algorithm of calculation of SOC by voltage and current.
31 +
32 +To change the parameters of the algorithm for calculating the battery SOC, select the menu "Cells → SOC estimation":
