6 FAQs about [Lithium battery over-discharge protection circuit]

How to protect a battery from over-discharging?

This degrades the recharge capability of the battery as well as its efficiency. Therefore, there should be a protection circuit which can monitor the level of charging of the battery by detecting the terminal voltage and protect the battery from over-discharging by cutting off the battery connection with the electronics device.

Why is over-discharge protection important for lithium-ion batteries?

However, with the increasing demand for safe transport and green recycling of lithium-ion batteries, over-discharge protection and even zero-volt protection have a broad application in more working devices. Over-discharge causes severe Cu dissolution and SEI degradation, which is mainly attributed to the raised anode potential.

What is a lithium battery protection board?

The lithium battery protection board is a core component of the intelligent management system for lithium-ion batteries. Its main functions include overcharge protection, over-discharge protection, over-temperature protection, over-current protection, etc., to ensure the safe use of the battery and extend its service life.

What does a battery protection circuit do?

A battery protection circuit will take the battery out of the circuit if the load current is too high. How battery protection circuits work Battery protection ICs typically use MOSFETs to switch lithium cells in and out of circuit. Lithium cells of the same age and part number can be paralleled and share one protection circuit.

What happens if a lithium ion battery is discharged deep?

Deep discharge can also lead to battery failure. An ideal lithium-ion battery charger should have voltage and current stabilization as well as a balancing system for battery banks. The voltage of a fully charged lithium-ion cell is 4.2 Volts. Once the bank reaches this voltage, charging should stop.

What happens if a lithium battery is overcharged?

When a lithium battery is charged beyond a safe charging voltage, the cell heats up extremely and its health is affected and its life cycle and current carrying capacity get reduced. To protect the cell from these types of conditions, a good battery management system must have an overvoltage built-in, and for the JW3313S IC, this is no exception.
