Design considerations
- Define clear safe operating limits for each cell and pack (voltage, current, temperature, SOC).
- Design a contactor control for pre-charge and charge/discharge operations
- Provide a reliable cell balancing strategy (active or passive), monitor the cells SOC and SOH for the expected lifetime
- Choose an architecture that fits the pack size (modular, distributed or centralized).
- Select components for high temperature capability, high current handling, low RDS(on), fast switching, and appropriate ESD/transient robustness.
- Implement ESD protection to provide reliable communication with the ECU and between the modules if designing a wireless BMS.
