DUAL SYSTEM HYBRID CHARGER MANAGMENT

An IHS (Information Handling System) may support multiple power sources and may support concurrent voltage inputs from each of these multiple power sources. An IHS may include multiple batteries, each of which is charged by a separate battery charging system. Embodiments of systems for charging and powering such IHSs are described, where such embodiments maximize the power that may be drawn from such concurrent power sources inputs, while avoiding inefficient modes of operation and while avoiding dead battery conditions. In many IHSs, certain power source couplings may also be configured to draw power from the IHS, such as Type C USB couplings. Embodiments also support efficient power supply outputs that avoid excessive battery depletion that may result in dead battery states.
