The described systems and methods relate to employing an Electric Air Charging System (EACS) to maintain a hybrid commercial vehicle (or the like) battery within a desired range of charge. The innovation facilitates reducing battery charge when the state of charge is too high, such as by adjusting air compressor cut-in and cut-out pressure thresholds to cause the air compressor to compress air for the brake system when there is excess charge in the battery, as well as triggering a brake regeneration protocol and/or other charge regeneration protocol(s) to restore charge to the battery when the state of charge of the battery is too low.
