6 FAQs about [New Energy Battery Over-discharge Instrument]

What is a battery over-discharge?

The over-discharge refers to the behavior of continuing to discharge a battery when it reaches the discharge cut-off voltage , . The over-discharge can occur in a variety of situations, such in cells without BMS in various aerospace and implantable medical devices.

Can a battery over-discharge be simulated?

However, one should note that in the development of the battery model used, the operation of a cell’s over-discharge of less than 0% SoC has not been considered, and thus the voltage response during over-discharge cannot be simulated.

What happens if a battery pack is over-discharged?

If one weak cell in the battery pack is over-discharged, the degradation of other cells is accelerated, which could lead to fatal problems. However, if the possibility of over-discharge of one cell is detected in advance, the BMS may disconnect the battery from the load to extend the battery life.

Is there an over-discharged cell in a lithium-ion battery pack?

What is battery charge/discharge testing?

Battery charge/discharge testing is carried out as part of performance tests during battery cell, module, and pack development and during the evaluation stage. This type of testing allows manufacturers to inspect the battery’s charge and discharge performance as well as its service life.

Can we detect over-discharge of a weak cell in a battery pack?

However, measuring the voltage of each cell in a battery pack/module with hundreds to thousands of cells connected increases the complexity of the circuit. This paper aims to detect the over-discharge of a weak cell in a battery pack in advance without measuring the voltage of each cell.
