High voltage lithium battery pack protection solution

What are lithium battery protection boards?

Issues such as overcharging, over-discharging, and high-current discharge may lead to battery damage, shortened lifespan, and even safety accidents. To safeguard against such occurrences, lithium battery protection boards came into being. These boards are engineered to provide monitoring and protection functions for low-voltage lithium batteries.

What is Infineon battery protection?

For that, Infineon ofers a wide range of battery protection solutions that, under stressful conditions, increase lifetime and eficiency of lithium batteries. The battery protection circuit disconnects the battery from the load when a critical condition is observed, such as short circuit, undercharge, overcharge or overheating.

Why are battery protection ICs needed?

Battery protection ICs are designed to enhance the safety of your battery pack by detecting various fault conditions such as overvoltage, undervoltage, discharge overcurrent, and short circuit in single-cell and multi-cell batteries.

What does a BPU protect against?

A battery protection unit (BPU) prevents possible damages to the battery cells and the failure of the battery. It does this by disconnecting the battery from charger or load under critical conditions that can lead to dangerous reactions.

What does a battery protection circuit do?

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.

What is a battery protection circuit / IC?

A battery protection circuit / IC is a solution that ensures safe charging and discharging, preventing damage and failures. Infineon Technologies offers easy-to-design-in IC solutions and reference designs for battery protection.
