FAQ sur les Li-Ion BMS
What is a Li-Ion BMS and why is it needed?
A Li-Ion BMS (Battery Management System) is a device used to monitor and manage the cells of lithium-ion batteries. It provides essential functions such as cell balancing, protection against overcharging, over-discharging, short-circuiting and overheating. These protections are crucial to maximizing battery life, ensuring battery safety and maintaining optimal performance.
How to choose the right Li-Ion BMS protection board for my device?
To choose the right Li-Ion BMS protection board, you need to consider several factors: the nominal voltage of your battery, the cell configuration (1S, 2S, etc.), and the admissible current. For example, for a 7.4V (2S) battery, you can opt for a "Li-Ion BMS Protection Board 2S - 7.4V" with the current corresponding to your needs. Also, be sure to check the specifications of your device to make the most suitable choice.
What is the difference between 2S - 7.4V 3A and 20A Li-Ion BMS protection board?
The main difference is the current capacity each board can handle. A 2S - 7.4V 3A Li-Ion BMS protection board is designed for applications requiring a maximum current of 3 amps, while the 20A one can handle up to 20 amps. The choice depends on the current demand of your specific application. Using a board with a higher current capacity than necessary can provide an extra safety margin, but it can also be more expensive.
What does the "with balance" specification on some Li-Ion BMS boards mean?
The "with balance" specification indicates that the Li-Ion BMS protection board has a cell balancing function. This function helps maintain equal voltages between all cells in the battery, which is essential for maximizing battery performance and life. A board with balance is especially recommended for multi-cell battery configurations.
Can I use a Li-Ion BMS protection board for a LiFePO4 battery?
No, it is important to choose a protection board that is specifically designed for the type of battery you are using. LiFePO4 and Li-Ion batteries have different charging and discharging characteristics. For example, if you are using a LiFePO4 battery, you should opt for a BMS protection board that is specifically designed for LiFePO4, such as the "8S 24V 60A LiFePO4 BMS Protection Board" or the "7S LiFePO4 BMS Protection Board for 24V 20A Battery".
How to install a Li-Ion BMS protection board correctly?
Installing a Li-Ion BMS protection board requires careful attention to wire connections and polarity. Each wire should be connected according to the diagram provided by the manufacturer, ensuring that the connections are solid and secure. It is recommended to consult the specific installation manual and, if possible, to hire a professional to ensure correct installation. Improper installation can lead to malfunctions or even
