What is a battery protection unit (BPU)?
You may want to refresh the page or try again later. A battery protection unit (BPU) prevents possible damage to the battery cells and the failure of the battery, enhancing the useful operating life of lithium-ion batteries by protecting the battery pack against charge current, discharge current, and pack short fault conditions.
Why should you use a battery protection IC?
That is why we design our battery protection ICs to detect a variety of fault conditions including overvoltage, undervoltage, discharge overcurrent and short circuit in single-cell and multi-cell batteries, so you can enhance the safety of your battery pack. ACTIVE ACTIVE This product has been released to the market and is available for purchase.
Do you need a Protection Board for a battery pack?
Different battery packs may have varying size and voltage requirements, and the protection board must be compatible with these characteristics. For example, a small battery pack may require a compact protection board, while a high-voltage battery pack would need a protection board capable of handling high voltages.
Do lithium batteries need a Protection Board?
Protection boards for lithium batteries offer monitoring protection. Low-voltage lithium batteries require a protection board. When using high-voltage lithium batteries, a battery management system (BMS) is typically chosen since these systems contain more functions for monitoring the state of the battery pack.
How do I choose a battery protection board?
The size and voltage of the battery pack are the foundational parameters for choosing a protection board. Different battery packs may have varying size and voltage requirements, and the protection board must be compatible with these characteristics.
What is the main function of a battery protection board?
The main function of the protection board is to monitor the state of charge (SoC), temperature, voltage, current, and state of health (SoH) of the battery pack. The MOS is controlled by the control IC. The MOS is always turned on during normal functions.
