22 -** Summation of cell voltages – the overall voltage is calculated as on sum of all cells in the battery;
23 -** Using voltage before contactors – the overall voltage is estimated as voltage before contactors measured by BMS.

25 -The values “Capacity” and “Resistance” are used to calculate the SOC of cells and the battery.
32 +The **"Parallel-Serial"** connection works as follows: a bunch of serial connected Logics are grouped into chains. A bunch of parallel connected chains are grouped to blocks. A bunch of serial connected blocks are grouped into string. By configuring the corresponding settings it is possible to create a complex string configuration. Current through each chain will be estimated as a fraction of overall current accordingly to the number of chains in a block.

27 -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.
34 +The values **“Capacity”** and **“Resistance”** are used to calculate the SOC of cells and the battery.
