Abstract: An apparatus may include a power rail, a subassembly, an additional subassembly, and an interface coupling the subassembly to the additional subassembly. The subassembly may include a load, an energy-storing component, a charger having an output coupled to the energy-storing component, and a reverse-current limiter having a first terminal coupled to the energy-storing component. The additional subassembly may include an additional energy-storing component, an additional charger having an output coupled to the additional energy-storing component, and an additional reverse-current limiter having a first terminal coupled to the additional energy-storing component. The power rail may cross the interface and may couple the load, an input of the charger, a second terminal of the reverse-current limiter, an input of the additional charger, and a second terminal of the additional reverse-current limiter. Various other apparatuses, systems, and methods are also disclosed.
