Key Design Challenges
The PMU and BMS must deliver multiple regulated voltage rails with high efficiency and low noise to power diverse components. Accurate battery monitoring and cell balancing are essential to maximize battery life and ensure safety. Protection against electrical faults such as overcurrent, overvoltage, and thermal runaway is critical. Additionally, secure authentication mechanisms are required to prevent counterfeit components and unauthorized access.
