Abstract: Systems and methods are provided for balancing battery modules following fast charging, particularly with respect to fast charging lithium ion batteries with metalloid-based anodes. Charge balancing among multiple battery modules connected in series may be carried out by short-circuiting fully charged modules while adjusting the voltage and/or current level supplied by a charger, to fully charge remaining modules. A balancing module comprising a controller and switching circuitry may be configured to implement the charge balancing in association with the charger and its battery management system, and monitoring the battery modules. Advantageously, disclosed switching balancing is more efficient than prior art passive balancing and simpler in implementation than prior art active balancing.
