The performance of a multi-cell battery pack is limited by the differences between the weakest and strongest cells in the pack.

IR’s Evaira advanced energy management system (EMS) utilizes bypass equalization ensuring all cells age uniformly by balancing the state of charge of all of the cells within a battery system.

The complete battery management system also features advanced algorithms, balancing, charge and discharge management and shutoff for electric vehicle applications for the automotive, commercial and military segments.

IR Advanced Development Group director Charles Chang said unlike alternative solutions, IR’s Evaira EMS brings a new level of sophistication to address the complexities involved with effective management of battery systems used in heavy duty platforms such as HEV and electric vehicles.
