6 FAQs about [What are the battery overheat protection devices ]

How a battery Protection Board works for overcurrent protection?

Here is how the battery protection board works for overcurrent protection: 1. Current monitoring: The battery protection board is connected to the positive and negative terminals of the battery pack and monitors the flow of current in real-time by means of a current sensor or current measurement circuit.

Why is battery overcurrent protection important?

However, the widespread use of batteries has also brought about current problems, where the presence of overcurrents can lead to catastrophic accidents such as equipment failures, fires, and even explosions. Therefore, overcurrent protection has become a key element in ensuring the safety of battery applications.

What happens if a battery is overheating?

This dangerous elevation in temperature is commonly referred to as overtemperature or overheating. If left unchecked, it can ultimately lead to thermal runaway — the point when a battery cell goes into meltdown with the subsequent release of electrolytes and dangerous gases.

Do all batteries have built-in protections?

Not all cells have built-in protections and the responsibility for safety in its absence falls to the Battery Management System (BMS). Further layers of safeguards can include solid-state switches in a circuit that is attached to the battery pack to measure current and voltage and disconnect the circuit if the values are too high.

What is a battery protection device?

Protection devices have a residual resistance that causes a slight decrease in overall performance due to a resistive voltage drop. Not all cells have built-in protections and the responsibility for safety in its absence falls to the Battery Management System (BMS).

What is a battery protection unit (BPU)?

A battery protection unit (BPU) prevents possible damages to the battery cells and the failure of the battery. Over-charge: is when the battery is charged over the allowed maximum capacity. High & low temperature: is when the internal temperature of the battery cells exceeds their safe operational temperature ranges.
