6 FAQs about [Internal resistance of high voltage energy storage cabinet]

Is internal resistance a dominant parameter of the battery model?

Internal resistance is revealed as the dominant parameter of the battery model. Internal resistance is extended as a new state be estimated together with SOC. A 83% performance improvement of the proposed method is verified by experiments. The estimation of the internal resistance will be beneficial for the SOH research.

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).

Does battery discharge rate affect internal resistance?

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.

What is the maximum internal resistance estimation error?

However, at the higher discharge rate (1.75C and 2.75C), when the temperature is lower than 25 °C, the internal resistance estimation error can reach 9.5 m Ω, while when the temperature is higher than 25 °C, the maximum estimation error of the internal resistance is only 1.97 m Ω (Fig. 9 d and f).

What is the internal resistance of Lib?

Ratnakumar et al. (2006) explored the internal resistance of LIB at 25 °C, 0 °C and − 20 °C respectively, under different SOC (20% to 100%) and discharge rates (using the direct current impedance measurement method).

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).
