50 50  ** Average cell SOC – the battery SOC is assumed to be equal to the average SOC of cells;
51 -** Min-Max SOC – the battery SOC is calculated based on the minimum and maximum SOC of the cells. Final SOC will be a) 100% if any cell has 100% SOC, b) 0% if any cell has 0% SOC;
52 -** Max-Min SOC – the battery SOC is calculated based on the minimum and maximum SOC of the cells. Final SOC will be a) 100% if all cells have 100% SOC, b) 0% if all cells have 0% SOC;

55 55  * Internal SOC corresponding to 100% – battery SOC that sets to be 100%.
