Hybrid energy storage module

摘要

The present disclosure is directed to an energy storage system using a combination of battery and ultra-capacitor storage components and having passive voltage control. An inductor is placed inline between the batteries and ultra-capacitors of the hybrid module. In another embodiment, the inductor/ultra-capacitor module is configured to be connected to a battery. The disclosed device is suitable for use in high-power applications where high-currents can have adverse effects on impedance-matching components.

主权项

1. A passively voltage-controlled ultra-capacitor module for an energy storage apparatus, comprising:
a battery positive terminal configured to be connected to a positive terminal of a rechargeable battery; a battery negative terminal configured to be connected to a negative terminal of the rechargeable battery; an inductor having a first lead, a second lead, and a low-permeability core, the first lead being in electrical communication with the battery positive terminal; at least one ultra-capacitor having a positive lead and a negative lead, the positive lead being in electrical communication with the second lead of the inductor and the negative lead being in electrical communication with the battery negative terminal; and a load positive terminal and a load negative terminal, configured such that a load connected to the load terminals is electrically in parallel with the at least one ultra-capacitor.
