6 FAQs about [Lithium battery pack protection voltage]

How to protect a lithium battery?

Use special lithium battery protection chip, when the battery voltage reaches the upper limit or lower limit, the control switch device MOS tube cut off the charging circuit or discharging circuit, to achieve the purpose of protecting the battery pack. Characteristics: 1. Only over-charge and over-discharge protection can be realized.

What is a battery protection circuit?

Protection circuits safeguard the battery pack against potential hazards: Overvoltage Protection: Disconnects the charger when a cell reaches its maximum voltage (e.g., 4.2V for Li-ion cells). Undervoltage Protection: Disconnects the load to prevent deep discharge.

What are some safety considerations for lithium batteries?

Lithium batteries have the advantage of high energy density. However, they require careful handling. This article discusses important safety and protection considerations when using a lithium battery, introduces some common battery protection ICs, and briefly outlines selection of important components in battery protection circuits.

Can this protection circuit module be used with non-lithium batteries?

This protection circuit module can also function using non-lithium battery chemistries that do not require a protection circuit when in use or when discharging. Some advantages with having the protection circuit module in the battery charger is that only one protection circuit module will be required, and it can reduce costs when using multiple batteries.

What type of batteries does this protection circuit apply to?

This protection circuit is generally used for rechargeable lithium batteries and where there will be multiple cells within the battery pack. Protection circuits embedded into battery packs provide full-time protection that is active throughout the lifecycle of the battery.
