The similar dQ/dV peaks between the pristine and over-discharged battery indicate that there is no substantial reduction in capacity, reflecting a surprising resilience to over-discharge stress. The Galvanostatic Charge–Discharge (GCD) tests shown in Fig. 4 (c) and (d) confirm these findings by characterizing the battery performance and identifying degradation

OD fault means discharging a battery below the discharge cut-off voltage. It is generally considered to have less harmful effects compared to OC. However, the aging induced by OD reduces battery thermal stability more than the aging induced by OC [90]. OD is typically caused by BMS failures, ESC and battery inconsistencies.

Discharge: In contrast, discharge occurs when the stored energy in the battery is released to power external devices or systems. During discharge, the chemical reactions within the battery cause electrons to flow from the negative electrode to the positive electrode through an external circuit, generating electrical current to power the load.

If the residual is higher than the set threshold, it means that the cell is over-discharged. Compared with the other overcharge and over-discharge methods, this is a real-time over-discharge fault diagnosis method.

Since LVP has a lower discharge voltage plateau (1.85–1.60 V and 1.97–1.79 V) (Fig. 8 d), the termination potential of the anode can be limited to a lower level (<3.4 V vs Li/Li +) during the process of over-discharge, thereby avoiding Cu dissolution and improving the capacity retention rate of the battery after a series of over-discharge operations from 49.55% to 95.91%.

How Can Battery Management Systems Help in Preventing Over Discharge? Battery Management Systems (BMS) help prevent over-discharge by monitoring battery voltage, managing charge and discharge cycles, and providing alerts and controls to ensure safe operation. The key functions of a BMS in preventing over-discharge include:
Over-discharge will rarely result in direct damage to lithium-ion battery. However, degradation on both electrodes especially on anode can be detected during recharge phase. In the worst case, a thermal runaway is also possible. Electrochemically irreversible solid-state amorphization occurs in case of deep over-discharge process which damages
Over discharge fault refers to the phenomenon that the battery voltage is lower than the discharge cutoff voltage during the discharge process. The fault causes the battery voltage to be lower than the charge cut-off voltage during charging, which significantly reduces the service life of lithium-ion batteries.
Although the discharge cut-off voltage can be set to avoid the occurrence of over-discharge, due to the inconsistency of battery system, if there is no efficient balance system, individual cells will still have over-discharge faults during the discharge process.
This method is simple and easy to use, so there are few diagnostic studies on overcharge and over-discharge faults. However, the cells of the battery system may still have a slight overcharge/over-discharge failure due to the inconsistency of the battery system.
