An energy storage system is provided that includes input terminals for receiving input energy from a remote power source and an energy storage device coupled to the input terminals. The energy storage device is operative to store at least of portion of the input energy and to supply stored energy to the input terminals. A pump device is also coupled to the input terminal and to the storage device. The pump device is operative to cause the energy storage device to store at least a portion of the input energy when the input energy level is above a first threshold level, and to cause the energy storage device to supply energy to the input terminals when the input energy level is below a second threshold level. The energy storage system is optionally provided with a current limiter for added protection against short circuits. In one embodiment, the current limiter is bi-direction; it protects against short circuits originating at both the power source and within the energy storage system. Also, the energy storage system is optionally provided with a safety discharge circuit that discharges the energy storage system upon its removal from the energy storage system.
