Abstract: A wireless electrical charging system and a method of operating same wherein operating parameters from a remote portion of the system are wirelessly transmitted to a system controller controlling the output voltage of an alternating power supply. The system controller executes an adaptive model control algorithm that allows the system controller to update the output voltage at a greater rate than the transmission rate of the operating parameters from the remote portion of the system.

Abstract: A wireless charging system, such as one used to charge electric vehicles, includes a number of charging stations. As a vehicle approaches the charging stations it transmits a signal commanding all of the charging station to transmit a magnetic station identification signal, each having a unique pulse pattern, through its source coil. The vehicle will then receive an identification signals from one particular charging station through the vehicle's capture coil and based on the unique pulse pattern of the identification signal received, transmit another signal instructing that particular charging station to begin generating a charging signal and instruct the other charging stations to stop transmitting their identification signals.

Abstract: A method of determining the available energy of a battery provides for measuring first and second open circuit voltage of the battery with a change of energy level occurring therebetween. The two open circuit voltages are correlated to a state of charge level and the measured amount of change of energy is divided by the change of the state of charge.

Abstract: A battery pack for a battery-powered vehicle is provided in accordance with the present invention. The battery pack for the battery-powered vehicle comprises battery modules coupled in series. The battery modules are configured to provide power to the battery-powered vehicle and each of the battery modules has a state-of-charge. The battery pack also comprises battery control modules (BCMs) that are coupled to the battery modules. Each of the battery modules is coupled to one of the BCMs and each of BCMs is configured to monitor a battery module parameter. Furthermore, the battery pack comprises a battery control interface module (BCIM) coupled to each of the BCMs. The BCIM is configured to receive the battery module parameter from each of the BCMs and independently adjust the state-of-charge of each of the battery modules based on the battery module parameter.

Abstract: An electroluminescent panel and method of making the same includes a plurality of layers on a transparent electrode in which each layer is formed with the same compatible polymer carrier resin base material so that the individual layers have an integrated uniformity. A polyester laminating resin is disclosed for the resin base material of each layer which is activated by a small amount of diisocyanate sufficient to provide temperature stability, but insufficient to transform the base material into a urethane. Also disclosed is an electroluminescent lamp which emits light only in discrete areas such as to produce a pattern of light in which the phosphor is applied in a pattern corresponding to the discrete areas which are to be illuminated. Similarly, the electrodes are restricted to the illuminated regions or areas, thereby conserving material as well as reducing the power requirements of the lamp.

Abstract: Flexible, electroluminescent panels or lamps employ a phosphor which is embedded in a coating formulation, in which a polyester laminating resin has been activated by a catalyst containing toluene diisocyanate or diphenylmethane diisocyanate, to provide a relatively high dielectric constant and to provide a flexible panel which is resistant to shorting, due to trimming, cutting or puncturing. The panel is characterized by relatively high efficiency and high light output.

Abstract: DC operated power supplies for electroluminescent lamps are self-inhibited from further oscillations and thus are current limited in the event that a failure occurs in an EL lamp which results in the EL lamp being shorted. Single ended and push/pull transformer power supplies are disclosed, and a transformerless solid state power supply is disclosed utilizing a voltage multiplier, and an inhibitor circuit at the output of the voltage multiplier responsive to substantial voltage drop upon the occurrence of a shorting of the EL lamp, to inhibit further oscillations and operations of the circuit.
