Over-Charge & Over-Discharge Protection of Lithium Batteries

Typical rechargeable lithium ion battery cells can safely operate down to 2.75V/cell. However, when an unprotected lithium cell is discharged past the minimum voltage level you run the risk of damaging the cell and ultimately lead to degraded cycle-life, unstable voltage characteristics and swelling of cells from internal chemical reaction.

What Is Lithium Battery Protection Mode?

Lithium battery overcharge protection allows the battery to shut off and the current goes away. The battery will cool down but if it goes back into protection mode after the battery turns back on you may have to reduce your load, reduce the charge rate, or improve the ventilation around the batteries.

Here''s what happens when lithium-ion batteries are drastically

The principle of overprotection of lithium battery

The protection circuit of the lithium-ion battery consists of a protection IC and two power MOSFETs. The protection IC monitors the battery voltage and switches to an external power MOSFET in the event of overcharge and discharge. Its functions include overcharge protection, overdischarge protection and Over current/short circuit protection.

What is "SCP"? – Protections of lithium (Li) -ion batteries from

The "Self Control Protector" (SCP), developed by Dexerials, is a fuse component that physically disconnects the charge/discharge circuit in the secondary protection of Li-ion batteries. The SCP ensures safety by severing the circuit when the battery becomes unstable or when the primary protection is not functioning correctly. The SCP''s

Lithium Ion Cell Protection

Overcharge. Lithium batteries can be safely charged to 4.1 V or 4.2 V/cell, but no higher. Overcharging causes damage to the battery and creates a safety hazard, including fire danger. A battery protection circuit should be used to prevent this. Over-discharge. Lithium batteries are completely empty when discharged to 2.5 V/cell. Discharging a

6 FAQs about [What is the overcharge protection current of lithium battery ]

What is lithium battery overcharge protection?

Can a lithium battery be overcharged?

How to protect a lithium battery from over-discharge?

Discharging a lithium cell this low is stressful to the cell and reduces cell lifetime. A good battery protection circuit will also provide over-discharge protection. Even protection circuit is added on lithium batteries, users should avoid over charge and over discharge during the use of lithium batteries.

Why do lithium-ion batteries need secondary protection?

However, even the protective functions of electronic circuits can occasionally fail due to abnormalities or semiconductor failures. In the case of lithium-ion batteries, secondary protection is incorporated due to the potential severe consequences of abnormalities, such as fire or explosion.

Inrush currents arise during the turn on, mainly when the battery is first connected to the load. The inrush currents can get high enough to either destroy the protection circuit or to blow of the protection fuse. A load pre-charge circuit would limit the inrush current during the turn on phase and protect both the battery and the load.
