Abstract: An Engine Start and Battery Support Module for a vehicle is provided that utilizes a bank of Ultra Capacitors (UCs) charged with or without running the vehicle's alternator to levels that support both engine starting assistance and hotel load support. The UCs' per-cell charge can be adjusted and raised during periods of low temperatures and even higher during ultralow temperatures. The adjustment, which can be dynamic and/or automatic, increases the UC energy storage capability. Further, the release of energy from the UCs is controlled by a pulse width modulation (PWM) controller based on the DC bus voltage. The UCs can be charged either from an onboard DC/DC converter, an AC hook up, or from smartly switching the banks of UCs between parallel and serial configurations.

Abstract: In some embodiments, an apparatus includes a housing and a purge valve. The housing defines a cavity and a lumen extending from a volume of the cavity to a volume outside the cavity. The purge valve is disposed within the lumen and includes an occlusion member. A portion of the occlusion member has a width substantially equal to a width of an end portion of the lumen such that the portion of the occlusion member is disposed within the end portion of the lumen when the purge valve is in a first configuration. The portion of the occlusion member being disposed outside the end portion of the lumen when the purge valve is in a second configuration.

Abstract: An EDLC device in which the double layer capacitors themselves are produced lithographically. The resultant EDLC can be of any capacitance and voltage combination for a particular application. The entire lithographically formed entity can be housed in a single container and rated according to its capacitance and voltage standoff characteristics. Through material control processes, the electrochemical composites developed onto the current collector is unilaterally equalized, providing the desired distributed voltage standoffs, thus promoting the ability to design high voltage independent cells without the normal electronic balancing circuitry associated with multiple series-connected electrochemical cells.
