Research on Overcharge and Overdischarge Effect ...
For our test we connected a dc power supply across a lithium battery the same way as a battery charger would be connected. The maximum charge voltage for lithium cells is usually on the order of 4.5 V but we''ve got the dc supply cranked up much higher than that to show what happens with overcharging.
To extend battery life and maintain good performance, it is crucial to avoid overcharge and over-discharge especially for the high-capacity battery. In some cases where overcharge/over-discharge is unavoidable, the monitoring of a battery, such as temperatures, voltages and current etc., should not be over-neglected.

Section snippets Overcharge tests under different test conditions. A 40 Ah lithium ion battery (240 mm × 150 mm × 14 mm) composed of two pouch cells (Cell 1 and Cell 2) connected in parallel was investigated in this study, as shown in Fig. 1.
Compared with over-discharge and overcharge, prevention is a more important step, and BMS is the most recommend. Treatment can only be remedial rather than repair, but it will not make the performance of the battery drop too seriously, and prevention can fundamentally eliminate the battery. The means of over-discharge and …
The battery protection circuit disconnects the battery from the load when a critical condition is observed, such as short circuit, undercharge, overcharge or overheating. Additionally, the battery protection circuit manages current rushing into and out of the battery, such as during pre-charge or hotswap turn on. BMS IC Microc ontroller Battery ...
