Abstract
The disclosure is directed to methods and systems for a battery configured to store a first energy in a chemical form of the battery at a battery voltage level; an electrical load configured to draw an electrical current from the battery in response to an energy requirement of the electrical load, wherein the battery voltage level is configured to decrease in response to the electrical current being drawn from the battery by the electrical load; and a capacitor module in electrical communication with the battery and configured to store a second energy as an electric field of the capacitor module at a capacitor voltage level. The capacitor module can be in electrical communication with the load via the battery and can be configured to convey at least a portion of the second energy to the battery or to the load in response to a voltage differential between the capacitor voltage level and the battery voltage level exceeding a threshold to prevent the battery voltage level from dropping below a battery voltage threshold.
