摘要： A charging system includes: a switch device and a control device. Each of charging ports is provided with a lid configured to open and close a corresponding one of the charging ports. The control device is configured to determine whether a predetermined charge prohibition condition is satisfied before starting charging an electric energy storage device using any one of the charging ports, and when the predetermined charge prohibition condition is satisfied, keep each of power paths from the charging ports to the electric energy storage device disconnected. The predetermined charge prohibition condition is satisfied when the lid of at least one charging port that is included in the charging ports and that is other than the charging port to be used is open.

摘要： The vehicle ECU acquires detection information from a detection sensor that detects pedestrians located around the vehicle, and determines whether there are pedestrians located around the vehicle based on this detection information. Then, when the vehicle ECU determines that there are pedestrians located around the vehicle, the vehicle ECU outputs to the supply device the instruction information to reduce the amount of transmitted power supplied from the supply device when there are no pedestrians around the vehicle.

摘要： Embodiments of this application provide a battery safety warning method and apparatus. The method includes: When determining battery warning information of a target vehicle, a battery warning system first obtains N performance values of a target vehicle battery, and then determines battery warning information that has a preset mapping relationship with each of the N performance values as battery warning information of the target vehicle. After the battery warning information of the target vehicle is determined, target processing policy information can be sent to a target processing device based on mapping relationships between different safety warning levels and processing policies corresponding to different processing devices. Correspondingly, after receiving the target processing policy information, the target processing device may perform a corresponding operation according to an indication of the target processing policy information.

摘要： Systems and methods are provided for intelligent energy source monitoring and selection control to enable power delivery in a multi-modal energy system. A multi-modal energy system includes a control system, power supply systems, and an electrical distribution system. The power supply systems are coupled to the control system. The power supply systems include a mains utility power system and at least one renewable power system. The electrical power distribution system is coupled to the control system. The control system is configured to monitor each power supply system to determine a power availability of each power supply system, determine an amount of power usage by the electrical power distribution system, and selectively connect and disconnect one or more of the power supply systems to the electrical power distribution system based on the determined power availability of the power supply systems and the determined power usage of the electrical power distribution system.

摘要： A switching device is mounted in a vehicle, and disposed between a connector connected to a DC power source, and a storage battery. The switching device includes: a transmission path connecting the connector and the storage battery; a semiconductor relay disposed on the transmission path; a switch disposed on the transmission path; a first sensor configured to measure a current flowing through the semiconductor relay, or a voltage of the semiconductor relay; and a controller configured to control opening and closing of the semiconductor relay. The switch is controlled by an external control signal, and the controller controls the semiconductor relay, based on the control signal and a measurement value of the first sensor.

摘要： Techniques for converting power received from a power grid at a first voltage and outputting a signal at a second voltage are discussed herein. A power converter with a transformer that has a 22.5 degrees phase shift between current output by corresponding pairs of secondary windings can be utilized to convert power of a first level to power of a second level. The transformer can output power from 30 secondary windings. The power converter can output power with a total harmonic distortion of 5% and an efficiency of 96% or higher. Further, power can be output by a transmission coil and received by a receive coil in a device, such as a vehicle, to wirelessly charge the vehicle.
