Technical FAQs 4

What are the components of a lithium-ion battery pack?

In the lithium-ion battery pack, there are the main electronic modules: the batteries (cells) connected in groups in parallel and series, the cell contact system, and the BMS (battery management system). The BMS is the brain of the battery pack.

What is a BMS in a battery pack?

A BMS is a PCBA (printed circuit board assembly) in the battery pack. The main components mounted on the BMS printed circuit board include: Microcontroller (MCU): It gathers and processes current signals from the CCS to monitor the voltages and temperatures of the cells.

How do you connect a BMS to a battery pack?

Connecting the BMS: B- Terminal: Connect to the main negative (-) terminal of the battery pack. B+ Terminal: Often already connected internally; check your BMS specifications. B1 (or B0): Connect to the most negative point (first cell's negative terminal). B2, B3,: Connect sequentially to the positive terminals of each cell in series.

What is a battery management system (BMS)?

A: A BMS monitors and balances the cells within a battery pack, preventing overcharging, over-discharging, and overheating, which can lead to cell damage or safety hazards. Q2: Can I use different types of battery cells in one pack?
