摘要： A vehicle battery charger and a vehicle battery charging system are described and illustrated, and can include a controller enabling a user to enter a time of day at which the vehicle battery charger or system begins and/or ends charging of the vehicle battery. The vehicle battery charger can be separate from the vehicle, can be at least partially integrated into the vehicle, can include a transmitter and/or a receiver capable of communication with a controller that is remote from the vehicle and vehicle charger, and can be controlled by a user or another party (e.g., a power utility) to control battery charging based upon a time of day, cost of power, or other factors.

摘要： In a control device for a power receiving device that is equipped with a power receiving coil that receives power contactlessly transmitted from a power transmitting coil of a power transmitting device, a switching element provided between the power receiving coil and a load is operated to perform a switching operation to control the output terminal of the power receiving coil. When executing the short-circuit mode that short-circuits between the two, the short-circuit mode is executed so as to avoid a region where the phase of the current in the inverter of the power transmission device is advanced.

摘要： The present invention suppresses leakage magnetic field. A power transfer coil configured to transmit or receive power includes: an inner coil; a first outer coil formed so as to surround the inner coil such that a magnetic flux opposite in phase to a magnetic flux outside the inner coil is generated outside the first outer coil, the first outer coil having one end connected to a first terminal and the other end connected to one end of the inner coil; and a second outer coil formed so as to surround the inner coil such that a magnetic flux opposite in phase to the magnetic flux outside the inner coil is generated outside the second outer coil, the second outer coil having one end connected to a second terminal and the other end connected to the other end of the inner coil.

摘要： Methods, systems, and computer-readable storage medium for improving the efficiency of charging an electric vehicle (EV) that follows a prescribed route. The efficiency of charging an electric vehicle is improved by receiving telemetry data from the EV, receiving charger data from a plurality of charges along the prescribed route, determining a charging plan for the EV based on a total cost per distance (TCD) of travel over each of the plurality of route segments that comprise the prescribed route and controlling a particular charger along the prescribed route to charge the EV according to the charging plan. To enable electrical arbitrage, both the EVs and wireless power charging stations installed in the ground are equipped for bidirectional charging. An individual EV (e.g., a transit bus on with set route and schedule) may store, convey, and discharge electrical power via a bi-directional charger using a predetermined charging strategy.

摘要： Disclosed are systems and methods for vehicle charging. A charging system can include a component to convey power to a vehicle to charge the vehicle. The charging system can include a module to store a certificate via a cryptographic technique. The charging system can include a data processing system coupled to the module, the data processing system including one or more processors, coupled with memory, to retrieve the certificate from the module, transmit, to a second data processing system, a request to establish a communication connection, the request including the certificate, and establish the communication connection with the second data processing system responsive to a verification of the certificate by the second data processing system. The data processing system can transmit, to the second data processing system, data corresponding to power conveyed by the component to the vehicle subsequent to verification of the certificate.
