The internal resistance of a battery is an important parameter for quality inspection during production and maintenance process. Get the best performance out of your battery by measuring it properly. The internal resistance of a battery can be used for two different purposes.
The internal resistance of a battery also plays a crucial role in power delivery. As current flows through the internal resistance, power is dissipated as heat. The formula P=I2RP = I^2RP=I2R quantifies this loss, indicating that power loss increases with the square of the current.
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.
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.
One of the urgent requirements of a battery for digital applications is low internal resistance. Measured in milliohms, the internal resistance is the gatekeeper that, to a large extent, determines the runtime. The lower the resistance, the less restriction the battery encounters in delivering the needed power spikes.
If one or more cells have high internal resistance or have degraded, they will become a bottleneck and limit the battery pack’s capacity. To improve the quality of the battery pack, it is important to select cells that all have an equivalent internal resistance. The second reason for measuring internal resistance is for battery maintenance.
