Abstract: Certain aspects of the present disclosure provide techniques for electric vehicle charging management. In one example, a method includes: building a graph representing an electrical topology of the electric vehicle charging facility and producing an updated graph by updating a state of the one or more network nodes based on electric current or power flow through the one or more passive electric components and updating a state of the one or more component nodes based on electric current or power produced or consumed by the one or more active electric components. The method further includes receiving a selected control strategy for the electric vehicle charging facility and adjusting an electric current or a power draw of an electric vehicle charging station in the electric vehicle charging facility based on the updated graph and the selected control strategy.

Abstract: A system whereby a disabling spike strip is deployed from the rear undercarriage of a vehicle is enabled by a dashboard-mounted switch powered by the vehicle electrical system. The spike strip comprises a main body and two (2) extensions which are deployed outwardly from each side of the main body by the action of internal compression springs. The undersides of the main body and each extension are provided with a plurality of skid pads. The spike strip further comprises front and rear stabilizer bars. The purpose of the pads and the stabilizers are to retain the location of the spike strip against the pavement and against the action of a trailing vehicle's wheels. The top portion of the spike strip comprises a plurality of fixed and spring-loaded spikes being designed to shred the tires of the trailing vehicle.
