The li-ion protection circuit serves as a safeguard for lithium-ion batteries, helping to prevent potential hazards and ensure safe operation. It consists of a small electronic circuit integrated into the battery pack or attached externally to the battery. This li-ion protection circuit provides several vital functions to protect the battery:
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. Overcharge
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.
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.
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.
We suggest that you should never use lithium ion/polymer batteries without protection cells. Without the protection, a slight mistake in their use could destroy the battery and they have a much higher risk of exploding or catching on fire. Text editor powered by tinymce. If you want to take your project portable you'll need a battery pack!
