Abstract
An energy management system can comprise a capacitor device, a first diode electrically coupled with the capacitor device and configured to bias an energy flow toward the capacitor device, a battery device having a greater energy density and a smaller power density than the capacitor device, the battery device configured to receive the capacitor energy from the capacitor device to store as battery energy, and a second diode electrically coupled with the capacitor device and the battery device. The second diode can convey capacitor energy from the capacitor device to the battery device and inhibit battery energy from passing from the battery device to the capacitor device. An electrical load electrically coupled with the battery device can receive battery energy from the battery device.
