Energy-Efficient Charge Redistribution Across High-Voltage Series Strings
Replacing passive resistive bleeders with high-frequency bidirectional flyback converters that shuttle up to 5A between individual cells without heat dissipation penalties.
Flyback Shuttling Efficiency
Operating at 92% round-trip electrical efficiency, active balancing recovers up to 8% of stranded energy that would otherwise be unusable due to premature cell cut-off.
- Up to 5A active balancing current per cell channel.
- 92% energy transfer efficiency eliminating localized hot spots.
- Real-time impedance tracking adapting balancing current to cell age.
- ASIL D certified galvanic isolation between cell monitor ICs.
