Patent attributes
A hypercapacitor energy storage system or device facilitates fast charging, stable energy retention, high energy to weight storage and the like. The hypercapacitor comprises an ultracapacitor in electrical connection with an energy retainer which may comprise a battery, a battery field, a standard capacitor and/or the like. The electrical connection between the ultracapacitor and energy retainer may stabilize the energy retention of the hypercapacitor and provide for long-term energy storage and prevent self-discharge. The hypercapacitor may be electrically couplable to an energy source such as the utility grid via a low voltage outlet (e.g., 110V or 220V) or other charging system and may undergo fast charging. The hypercapacitor may be electrically couplable to and/or integrated with various systems or devices requiring energy storage and/or usage and may provide energy thereto.
