6 FAQs about [Relationship between battery internal resistance and current]

What factors affect the internal resistance of a battery?

The internal resistance of battery is affected by multiple factors (state of charge, temperature, discharge rate etc.). Ahmed et al. (2015) analyzed the internal resistance of battery by the impedance spectroscopy, and they found that the internal resistance of the LIBs was related to the temperature and state of charge (SOC).

How to measure internal resistance of a battery?

There are two different approaches followed in the battery industry to measure the internal resistance of a cell. A short pulse of high current is applied to the cell; the voltages and currents are measured before and after the pulse and then ohm’s law (I = V/R) is applied to get the result.

Is internal resistance related to battery discharge current?

Is more correct to say that internal resistance is related to battery discharge current. Indeed, a battery with higher discharge current will have a smaller internal resistance. For example, a LiPo prismatic cell of 3000mAh used to have a bigger discharge current than a cylindrical LiIon with the same capacity.

What is a low internal resistance battery?

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.

Does temperature affect battery 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.

How does SoC affect the internal resistance of a lithium ion battery?

However, the SOC has a higher influence on the internal resistance under low temperatures, because SOC affects the resistance value of the battery by influencing the disassembly and embedding speed of lithium ions in anode and cathode as well as the viscosity of electrolyte (Ahmed et al., 2015).
