Challenges and Limitations of Passive BMS Limited Balancing Efficiency. Energy Dissipation: Passive BMS dissipates excess energy as heat, leading to energy losses and reduced overall efficiency. Slow Balancing: The resistive balancing process is relatively slow compared to active balancing methods, which can lead to longer balancing times.
Passive cell balancing in BMS or passive balancing BMS involves the dissipation of excess energy from higher energy cells until they align with or equal the voltage of the lower voltage cell. This technique employs either fixed shunting or switching shunting resistor methods for achieving balance within passive cell balancers.
