6 FAQs about [Lithium battery pack has inherent undervoltage]
Why is undervoltage protection important when using lithium-ion batteries?
crucial when using lithium-ion batteries because if the battery is discharged below its rated value, the battery will become damaged and potentially pose a safety hazard. In addition to undervoltage protection, it is important to ensure that the battery is discharging a safe current value. Combining undervoltage protection and overcurrent
Do lithium ion batteries have overvoltage and undervoltage effects?
Lithium-ion batteries can experience overvoltage and undervoltage effects. As noted in Figure 1, the operating voltage and temperature of the battery must be maintained at the point marked with the green box. If it is not, the cells can be damaged. Figure 1. Operating window of a lithium-ion cell. Image used courtesy of Simon Mugo
What causes a lithium ion battery to overcharge?
Low temperature also causes lithium plating due to non-uniformities occurring within the cell elements originating from the manufacturing defects or misuse of the cell. Over-discharge is when voltage is drained from the battery cell to below two volts.
What is the operating window of a lithium ion cell?
Operating window of a lithium-ion cell. Image used courtesy of Simon Mugo Overvoltage is when the charging voltage of the lithium-ion battery cell is increased beyond the predetermined upper limit, typically 4.2 V. The excessive current flow into the lithium-ion cell causes overheating and lithium plating, which leads to battery failure.
Why do energy storage systems use lithium-ion batteries?
Energy storage system data Energy storage systems often take lithium-ion batteries as storage devices. The high safety risks of battery fires and explosions with the large number of battery modules make early and accurate diagnosis of lithium-ion battery faults particularly important.
How does undervoltage affect a cell?
Undervoltage occurs when the cell falls below the minimum expected voltage of 2.0 V due to being stored for a long time without being charged, affecting the anode and cathodes of the cells. Temperature effects can harm the cell in low or high temperatures.
