A charge system for a vehicle includes a battery charge path, a current limiting element, and a capacitor. The current limiting element is arranged in series along the battery charge path, and in parallel relative to the capacitor. During an inrush event, the current limiting element is configured to initially restrict current flow between the battery and the load, increasing the rate and amount with which the capacitor is used to meet the current demands of the load. Thus, the current limiting element allows the battery to gradually increase its supply of current to the load in a manner that does not jeopardize its health. Once a steady state level of charging has been reached, the current limiting element is able to reduce its resistance to current flow, and the battery is able to safely take over as the primary source of current to the load.
