Direct Current Internal Resistance, DCIR or DCR can be measured with a battery tester by applying a low current followed by higher current on the battery within a short period, and
Ideally, a battery's internal resistance should be zero, allowing for maximum current flow without any energy loss. In reality, however, as illustrated in Fig.1, internal resistance is always present. Let's consider an example to illustrate this. The battery voltage is determined by the internal resistance and the output current.
Internal resistance can be thought of as a measure of the “quality” of a battery cell. A low internal resistance indicates that the battery cell is able to deliver a large current with minimal voltage drop, while a high internal resistance indicates that the battery cell is less able to deliver a large current and experiences a larger voltage drop.
One can mention the IEC 61960 standard or PNGV (Partnership for a New Generation of Vehicles) procedure for example. Measurement methods for the internal resistance of batteries can be divided up into two categories: DC (Direct Current) techniques and AC (Alternating Current) techniques.
The lithium ion battery internal resistance refers to the resistance of the current flowing through the battery when the battery is working, and indicates the degree of obstruction of a circuit element to the transmission of current. General lithium ion battery internal resistance is divided into AC internal resistance and DC internal resistance.
When the battery's internal resistance, R DC, is 1 Ω, and the load, R, is 9 Ω, the battery outputs a voltage of 9 V. However, if the internal resistance increases to 2 Ω, the output voltage drops to approximately 8.2 V. In summary, internal resistance influences a battery's current-carrying capacity.
If the internal resistance of the battery cell is not provided by the manufacturer, as we’ll see in this article, using the discharge characteristics of the battery cell, we can calculate the internal resistance of the battery cell, for a specific state of charge value.
