18		-** **Serial **– all cells are connected in series in a single string.
19		-** **Parallel-Serial **– cells are grouped in parallel and serial items;

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.
	24	+The values “Capacity” and “Resistance” are used to calculate the SOC of cells and the battery.

34		-The values **“Capacity”** and **“Resistance”** are used to calculate the SOC of cells and the battery.
	26	+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.
