Many friends may find that when using lithium battery packs, some lithium batteries are labeled with protective plates, while others do not have protective plates. So today, let's talk about why we need to install protective panels, right?

People may ask what is a lithium battery pack protection board? A protective board is a circuit board that serves as a packaging component and is mainly composed of electronic circuits. Accurately observe the voltage of the battery and the current of the charging circuit in an environment of -40 to 85, and timely control the flow rate of the current circuit.
Lithium battery pack protection boards typically include control ICs, MOS switches, resistors, capacitors, and some auxiliary devices. In all normal circumstances, the control IC that controls the MOS switch is the battery cell and external circuit. When the battery voltage or circuit current exceeds the specified value, immediately control the MOS switch to disconnect to protect battery safety.
The protection board of the lithium battery pack protects the lithium battery and has four major functions: overcharge, overlap, overcurrent, and reverse connection protection.
Why do lithium battery packs need protective plates?
Adding a protective plate to the battery is for user safety. Lithium battery packs have their own safety discharge and charging, as well as overcurrent restrictions. Adding a protective plate is to ensure that the use of lithium battery packs does not exceed the safe range. Choose a charger with overcharge protection for charging lithium batteries. If it doesn't have a board, it will remain when using a charger without overcharge protection. Just like a person who is full and you keep making them eat, only to end up being stretched out, the same goes for lithium batteries. The function of adding a protective board is to stop charging after being fully charged.
The principle of discharge overcurrent detection is the same. Therefore, batteries with protective plates can be added to control the operation of lithium batteries in designated working environments. So within the allowable range of lithium battery packs, safety can be greatly improved.
