Similar to the correlation patterns shown in Section 4.1, the figure shows that internal resistance initially decreases sharply from a higher value and then gradually increases. Meanwhile, the batteries lose a small fraction of the initial capacity.
For a variety of BTM technologies, the battery’s internal resistance always plays a critical role in the heat generation rate of the battery. Many factors (temperature, SOC and discharge rate) impact on the internal resistance, however, scant research has explored the effect of battery discharge rate on the internal resistance.
The deviation between the two measured values is around 70 m Ω, the lower the battery ambient temperature, the greater the internal resistance value. This finding is consistent with Yang’s study (Lai et al., 2019). Therefore, the temperature is one of the crucial factors which can influence the battery internal resistance. Fig. 5.
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.
In contrast, this paper demonstrates that the internal cell resistance is an excellent candidate feature for battery health prediction using the same dataset. Its dynamics correlate very well with battery health at the early stage of cycling, and simple models are sufficient to capture the dynamics.
In recent years, many studies on the modeling of battery resistance have been conducted by researchers (Chen et al., 2018). The internal resistance of battery is affected by multiple factors (state of charge, temperature, discharge rate etc.).

Why is it Important to Measure Battery''s 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. The higher the internal resistance, the greater the energy loss, which is converted …
