6 FAQs about [Battery internal resistance detection technology in computer room]
How to measure battery internal resistance?
In 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 .
How to test battery capacity?
It is not easy to test battery capacity directly, while the detection of internal resistance is much simpler. For example, the battery internal resistance can be easily obtained by the direct current internal resistance (DCIR) method or the hybrid pulse power characterization (HPPC) method [18, 19].
How to improve internal resistance detection accuracy?
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
How to determine residual capacitance and internal resistance of unknown battery?
The method of determining of residual capacitance and internal resistance into one express test for the unknown battery without the extraction of the system is considered. Analysis of dependence, obtained in a research, leads the estimation of the internal resistance of battery to the point of testing.
Can a pulse detection circuit ensure the accuracy of battery internal resistance?
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.
What is the ohmic resistance of a battery?
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 .
