Abstract: A high-capacity electrical energy storage device (HCEESD) comprising a capacitor having at least one power cell, a pair of high-voltage main power terminals configured to receive and store electrical energy from an external main power source, and a pair of fixating auxiliary power terminals configured to receive a fixating voltage from an auxiliary power source that causes the stored electrical energy to be retained so long as the auxiliary power source remains active. The HCEESD may include a plurality of power cells electrically connected in parallel and one or more fixating cells oppositely polarized to the power cells that assist in suppressing energy decay of the HCEESDs. An electric locomotive that includes multiple energy banks of HCEESDs configured to independently provide electrical energy to the electric locomotive, which may be a maglev vehicle designed to operate on special tracks with electromagnets inductively polarized using electrical power from on-board HCEESDs, is also disclosed.

Abstract: A high-capacity electrical energy storage device (HCEESD) comprising at least one capacitor having a pair of high-voltage main power terminals configured to receive electrical energy from an external main power source and a low-voltage auxiliary power source providing an amplified fixating voltage to a pair of low-voltage auxiliary power terminals of the at least one capacitor that causes the stored electrical energy to be retained so long as the low-voltage power source remains active. An electric locomotive that includes multiple banks of HCEESDs comprising capacitors in accordance with the invention connected in parallel to provide electrical energy to the electric locomotive without catenaries or a third rail is also disclosed.
