BMS Assembly & Connector Wiring
Want to learn how to properly install a Battery Management System (BMS) and the connector wiring? Here''s a clear, step-by-step
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?
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.
Figure 1 illustrates a typical lithium-ion cell SOA, and a well-designed BMS will protect the pack by preventing operation outside the manufacturer's cell ratings. In many cases, further derating may be applied to reside within the SOA safe zone in the interest of promoting further battery lifespan.
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.
