107	107	Calculation of the resistance of cells is carried out in two ways. The first method is used when the battery passes from a relaxation state to a charge or discharge state, wherein the cell resistance value

	113	+where U — the cell voltage measured in the charge or discharge state, V; U,,ocv,, — cell voltage measured in the state of relaxation (before switching to the state of charge or discharge); I,,stable,, — stabilized current through the cell in the state of charge or discharge.
