On a lithium battery cell production line, measurement of open circuit voltage is one of the important inspections for detecting defective products. The battery voltage when the load is not connected is referred to as an open circuit voltage (Open Circuit Voltage). Because the battery has a self-discharge characteristic, the open circuit voltage value is thus gradually decreased. If the battery has internal defects, it will produce more self-discharge. On the production line, we detect the battery with the open-circuit voltage lower than the specified value and reject it as a defective product. DCR refers to the resistance exhibited by a power supply or element in a circuit when a direct current is applied, and in battery manufacturing, DCR is a method of measuring electrical disturbances while also evaluating the resistance particle strength inside a cell.
