Battery protection board is designed to protect the battery, so many batteries have protection board. But many people don’t understand the function of battery protection board. I will introduce the function of battery protection board to the reader.
Battery protection board is designed to protect the battery, so many batteries have protection board. But many people don’t understand the function of battery protection board. I will introduce the function of battery protection board to the reader.
Overcharge protection function
Battery protection board has overcharge protection function. When the battery reaches a certain fixed voltage , it will instruct the charger to stop charging, by controlling the transistor that controls overcharging and entering a disconnected state. The achieves the goal of stopping the charging process.
Over-discharge protection function
Over-discharge protection function that means when the battery voltage reaching a certain low level, the battery will stop discharge. This is the self protect of battery. This means that the system that controls over-discharge is turned off, making the battery impossible to discharge. This process is suitable for the overcharge protection function, and the action during detection is completely opposite.
Over-current protection function
Over-current protection function that means when consuming a large current, the battery will stop discharge. The purpose of this function is mainly to protect the battery, make sure the battery works in the safe state. After the current test, the battery is disconnected from the load and returns to normal state, enabling it to be recharged or discharged.
Short circuit protection function
Short circuit protection’s principle and over-current protection function is the same. When the battery has short circuit, the battery protection battery will cut the current. The purpose is also protect the battery.
There is the main function of battery protection board. You can read the essay if you don’t understand . I hope this essay can help you.
