Battery Charging Control Methods, Electric Vehicle Charging Methods, Battery Charging Apparatus and Rechargeable Battey Systems
The invention represents an algorithm to provide a form of regulation up and down services to the electric power grid using a plug-in electric hybrid vehicle (PHEV/EV) or electric vehicle (EV). The basis for this regulation will come from frequency measurements of the power grid. The actual charge rate of the PHEV/EV charger will be adjusted using this regulation signal and information about any charging constraints imposed upon the charger (such as a desired finish time).
Battery charging control methods, electrical vehicle charging methods, battery charging control apparatus, and electrical vehicles
Battery charging control methods, electrical vehicle charging methods, battery charging control apparatus, and electrical vehicles are described. In one arrangement, battery charging control methods include accessing price information for electrical energy supplied by an electrical power distribution system and controlling an adjustment of an amount of the electrical energy from the electrical power distribution system used to charge a rechargeable battery at different moments in time using the price information. Other arrangements are described.
PLASMA MODIFICATION OF ADHESIVE AND SUBSTRATE SURFACES FOR USE IN ADHESIVEJOINT APPLICATIONS (iEdison No. 0685901-23-0109)
Weak interfacial bonding between carbon-fiber-reinforced thermoplastic polymer (CFRTP) and thermoset adhesive is the Achilles' heel for adhesive jointing of CFRTP with other materials. In this invention, we propose a surface modification method that involves plasma treating both adhesive and substrate surfaces to enhance the fracture resistance of dissimilar metal-CFRTP materials bonded with adhesive. We used a high-power plasma treater with compressed air gas to treat the substrate surfaces, and a lower-power plasma treater with a mixture of oxygen and argon gases to treat the adhesives. To test the effectiveness of our proposed method, we performed single lap shear tests on metal-CFRTP joints with optimized treatment parameters for both adhesive and substrates. Our results demonstrate that lap shear strength (LSS) of the joints can be improved by more than 250% compared to as-received counterparts, and more than 50% compared to the case of only treating substrate surfaces. This invention has the potential to make significant contributions to the field of adhesive joining by enhancing the damage tolerance of CFRTP joints with other materials.
Controller for Hybrid Energy Storage
A controller is disclosed for hybrid systems providing power to an electrical power grid. The controller reduces wear on hybrid systems by having only a fast unit tuned to track fluctuations of a regulation signal in a normal mode of operation. By contrast, the slow unit does not track fluctuations in the regulation signal in the normal mode of operation, which reduces wear on the slow unit. The normal mode of operation is defined by an energy range of the fast unit. Energy band parameters associated with the energy range can be dynamically modified in order to optimize the efficiency of the hybrid system.
