To measure the internal resistance of a battery, there are two methods, one is the AC method and the other is the DC method. The so-called ACIR is the value of internal resistance of the battery measured by AC method.
Battery internal resistance is a crucial parameter that determines the performance and efficiency of a battery. It is the measure of opposition to the flow of current within the battery due to various factors such as the electrolyte, electrodes, and connections.
According to IEC61960, t he DC resistance can be measured as follows: A DC current step is applied to measure the change in the cell’s voltage. Battery resistance is defined as the change in voltage over the change in current when a discharge current of 0.2C is applied for 10s followed by a discharge current of 1C for 1s.
Direct current internal resistance (DCIR) of batteries is the r esistance of current flowing through the battery, with the standard unit of measurement called the ohm.The value of DCIR is not fixed, and varies depending on multiple factors, such as battery materials, electrolyte concentration, temperature, and depth of discharge.
