Abstract: System and methods for electric vehicle charging are described. A preferred charging rate associated with an electric vehicle is determined. The preferred charging rate is compared with a first charging rate associated with a utility service current source and a second charging rate associated with an electrical energy storage device. The utility service current source supports the first charging rate and the electrical energy storage device supports the second charging rate, where the second charging rate is greater than the first charging rate. A transfer switch is instructed to select one of the utility service current source and the electrical energy storage device based on the comparison. The transfer switch is coupled to an electric vehicle charger and supplies current to the electric vehicle charger via the selected current source. The electric vehicle is charged at the preferred charging rate using at least the selected current source.

Abstract: Systems and methods for isolated energy measurement are disclosed. A net current between a first point of a circuit and a second point of the circuit is detected based at least in part on a magnitude and a direction of a current provided by a first current transformer coupled to the first point and a magnitude and a direction of a current provided by a second current transformer coupled to the second point. The first current transformer has a first polarity and the second current transformer has a second polarity that is opposite to the first polarity. A voltage of the circuit between the first point of the circuit and the second point of the circuit is detected. A measured energy usage of the circuit between the first point and the second point is determined based on the detected net current and the detected voltage.

Abstract: Systems, methods, and devices for refueling a vehicle are discussed herein. A vehicle charging station includes a power distribution interface, a receiver component, and an authorization component. The power distribution interface is configured to provide electrical power to a power receiving interface of a vehicle. The receiver component determines identification information that uniquely identifies the vehicle. The receiver component is positioned to determine the identification information corresponding to the vehicle when the power receiving interface is in electrical communication with the power distribution interface. The authorization component is configured to allow flow of electrical power to the vehicle in response to authorization based on the received identification information.

Abstract: A modular battery pack system includes a chassis for selective insertion and removal of a plurality of battery cells. The chassis includes a plurality of battery cell compartments, a backplane assembly, and one or more mechanical actuators. The plurality of battery cell compartments are each configured to receive a battery cell. The backplane assembly is configured to provide electrical connection from one or more batteries in the plurality of battery cell compartments to a load. The one or more mechanical actuators are configured to selectively establish electrical communication between the backplane assembly and the one or more batteries when the battery cell is within one of the plurality of battery compartments.

Abstract: Systems, methods, and devices for authorizing a vehicle for refueling are discussed herein. A method for authorizing a vehicle includes maintaining a list of preauthorized vehicles. The list of preauthorized vehicles includes entries uniquely corresponding to specific preauthorized vehicles. The list is maintained at a geographical charging site remote from one or more geographical charging locations. The method also includes transmitting to the geographical charging sites an update to the list of preauthorized vehicles. Each geographical charging site may include one or more charging stations. The method further includes receiving usage updates for the one or more geographical charging sites.
