Bodyguard for protecting lithium batteries - lithium battery protection board

    I believe everyone is familiar with lithium batteries and can see their presence in daily life. Therefore, when using lithium batteries, it is very important to have our lithium battery protection board! It plays a great role in protecting our lithium batteries when we use them. Let's follow the editor to learn about the bodyguard of lithium batteries - lithium battery protection board!

    Lithium battery protection board, in simple terms, is a circuit board that provides protection for our lithium batteries. Our lithium battery protection board is mainly composed of electronic circuits, which accurately monitor the voltage of the battery cells and the current of the charging and discharging circuit at all times in an environment of -40 ℃ to+85 ℃, and timely control the on/off of the current circuit. Ordinary lithium battery protection boards usually include control ICs, MOS switches, resistors, capacitors, and some auxiliary devices. Among them, the control IC controls the MOS switch to conduct the battery cell with the external circuit under normal conditions. When the battery cell voltage or circuit current exceeds the specified value, it immediately controls the MOS switch to turn off, protecting the safety of the battery cell.
