Lithium battery protection board b1b2b3 is a protection circuit board in the lithium battery pack, used to protect the safety and life of the lithium battery pack.
Among them, b1 is the overcharge protection circuit board, which can automatically disconnect the circuit when the battery voltage reaches a preset value to prevent the safety risk caused by the battery overcharge.
b2 is an overdischarge protection circuit board that can automatically cut off the circuit when the battery voltage drops to a preset value to prevent battery overdischarge resulting in damage and reduced life.
b3 is a balanced protection circuit board that can detect the voltage of the individual cell in the battery pack and adjust the voltage balance of the cell inside the battery pack to extend the life and stability of the battery pack.
Through the above protection measures, the lithium battery pack can work more stably and safely, extending the life of the battery pack, and the protection circuit board b1b2b3 is the core component of realizing these protection measures.
Lithium battery protection board b1b2b3 is a protection circuit board that controls the charge and discharge of lithium battery and the temperature. Lithium batteries are prone to overcharge, overdischarge and overheating, so a protection circuit is needed to control the charge and discharge of the battery and the temperature.
b1b2b3 is the three key components on the lithium battery protection board, of which b1 is used to control overcharge, b2 is used to control overdischarge, and b3 is used to monitor and protect the temperature of the battery.
These protection circuits can ensure the stable operation of the battery for a long time without damage.
In addition to b1b2b3, the lithium battery protection board has other important components, such as battery equalization circuit, undervoltage protection circuit and overcurrent protection circuit. These components also play a very important role in ensuring the stability and safety of lithium batteries.
What is the lithium battery protection board b1b2b3 B1 represents the positive electrode of the first battery, B2 represents the positive electrode of the second battery and so on, B and B- are the total battery plus or minus. In fact, the first and second sections here refer to several strings of batteries inside the lithium battery protection board
Battery protection board b1b2b3b4 refers to a battery protection circuit board, in which b1, b2, b3, b4 respectively correspond to the positive terminal, negative terminal, charging terminal and discharging terminal of the battery, and is equipped with a protection circuit at each extreme.
The main function of the circuit board is to protect the battery, prevent the battery overcharge, overdischarge and short circuit, so as to extend the service life of the battery.
Represents the positive terminals of the 1, 2, and 3 batteries respectively. The circuit board is a 3-string lithium battery circuit board, the lithium battery can be cascaded by screen printing.
Represents the first positive electrode (B1), second positive electrode (B2), third positive electrode (B3), fourth positive electrode (B4), fifth positive electrode (B5) and the negative electrode (B-) of the battery on the protection board of the electric version of the hand battery.
