AI Customer ServiceIn addition, the pulse discharge method is a commonly used detection method , but the pulse time of this method is in units of seconds and cannot accurately obtain the battery internal resistance when the battery is loaded. In this paper, the battery internal resistance is measured using the direct current short-pulse (DCSP) method .
In practical applications, battery voltage oscillations caused by external loads can affect the internal resistance detection accuracy. However, this can be effectively improved by reducing the pulse time and increasing the pulse current in the device. 3. Correlation between Internal Resistance and Capacity
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).
Here, the voltage value of the DC power supply (ε) is equivalent to the OCV. The ohmic resistance (Ri) in the model is the DC internal resistance of the battery. This parameter shown in previous studies is closely related to the SOC, temperature, and life of the battery .
The pulse detection circuit can ensure the accuracy of battery internal resistance as long as the battery voltage does not fluctuate greatly with the load current in the test. In practical applications, battery voltage oscillations caused by external loads can affect the internal resistance detection accuracy.
After establishing the relationship between these two parameters by linear fitting, the capacity result obtained by the internal resistance measurement is proved to be effective in the SOC estimation by experiments. 2. Internal Resistance Measurement
