Over-discharge protection The protection board automatically cuts off the discharge circuit when the battery discharges to the set voltage. Prevent the battery from over-discharging. 3.

Why do I need a load pre-charge circuit?

The inrush currents can get high enough to either destroy the protection circuit or to blow of the protection fuse. A load pre-charge circuit would limit the inrush current during the turn on phase and protect both the battery and the load. The pre-charge circuit is required whenever any of the following conditions occur:

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.

Why does a load pre-charge circuit limit inrush current?

Inrush currents arise during the turn on, mainly when the battery is first connected to the load. The inrush currents can get high enough to either destroy the protection circuit or to blow of the protection fuse. A load pre-charge circuit would limit the inrush current during the turn on phase and protect both the battery and the load.

What is a pre-charge current?

During the first stage a pre-charge current is applied if the battery is deeply battery. The pre-charge current is usually set to 10 percent of the fast-charge current. Once the battery voltage is greater than 2.8-3.0 V, the second stage of charging can be performed using the fast-charge current. discharged (usually below 2.8 to 3 V).
