A rechargeable energy storage system (RESS), in accordance with a non-limiting example, includes a first energy storage cell including a first outer surface, a second outer surface, a first lateral side, and a second lateral side. The second lateral side includes a first structural side plate including a first side member extending from the first outer surface toward the second outer surface. A second energy storage cell includes a first outer surface portion, a second outer surface portion, a first lateral side surface, and a second lateral side surface. The first lateral side surface includes a second structural side plate including a second side member extending from the second outer surface portion toward the first outer surface portion. The first side member stacks with the second side member to form an interface joining the first energy storage cell with the second energy storage cell.

Systems and methods are provided for determining and correcting air/fuel imbalance between cylinders of an internal combustion engine. A deactivation strategy is determined and implemented. An evaluation is made of whether the engine is operating with an air/fuel imbalance between cylinders. When an imbalance is identified, an alternate deactivation strategy is implemented. Based on outcomes of the alternate deactivation strategy, a source cylinder of the air/fuel imbalance is identified, and fuel flow to the source cylinder is corrected.
