Active balancing of lithium-ion cells for maximum power discharging
… BMS in standard EV batteries employ series cell balancing only while charging. The discharge balancing technique can be used to increase useable capacity from an EV battery because at the end of a cycle the stronger cells have some remaining capacity which can used to assist the weaker cells. …

Beyond PWM: Active balancing, start-up and ZVS for multi-level converters with applications in renewable energy systems
… output current. To reduce the induced imbalance, active balancing is implemented with a single voltage measurement of one specific flying capacitor. To correct for flying capacitor imbalance for more generic conditions, valley current detection has previously been proposed. However, prior work did …

A hybrid battery cell voltage equalizer considering thermal behavior and capacity fade characteristics
… the thesis introduces a hybrid battery cell balancing topology designed to achieve optimum balancing speed and enhance battery health by reducing temperature rise and frequent battery cycling during balancing. The proposed hybrid balancing topology combines active balancing for cell-to-pack …

The Development of a High-Performance Distributed Battery Management System for Large Lithium Ion Packs
… equipped with a 25A DC/DC converter to perform active balancing between cells in a string. This converter can transfer charge to (or from) a cell of higher potential and a cell of lower potential at the same time. The balancing circuit has a peak efficiency of 85.3%. The system draws only 53mA …

Listening to our stories in dusty boxes: Indigenous storytelling methodology, archival practice, and the Cherokee Female Seminary
… knowledge-making through storytelling as an active, balancing force. The result is revisionist history, but it’s also a returning present reality--the reality that these archives have always already been indigenous even in a colonized state, the reality that our research methodology need to …
