Product type
A Passive Balancing Battery Management System (BMS) is an essential component in energy storage solutions that ensures the optimal performance and longevity of battery packs. It works by redistributing charge among individual cells to prevent overcharging and undercharging, thus maintaining balanced voltage levels across the battery pack. Typically constructed from electronic components, it monitors cell voltages and temperatures to manage the charging and discharging processes effectively.
| Input voltage range | 12V to 48V |
| Number of cells supported | Up to 16 cells in series |
| Balancing current | 100mA to 1A per cell |
| Communication protocols | CAN, RS485, or UART |
| Temperature monitoring | Up to 8 temperature sensors |
When selecting a Passive Balancing BMS, consider the voltage and capacity of your battery pack, as well as the number of cells in series. It's important to specify the balancing current required for your application and any communication protocols that need to be supported. Additionally, inquire about temperature monitoring capabilities and whether the system meets any relevant safety certifications.
