An Electric Vehicle (EV) charging system and method is disclosed. The system includes EV with a battery, charge control device, a portable transponder, a charging station with energy management device, a cable, a transmitter. The vehicle ID and SoC information is received from the vehicle, and the information is transmitted to the internet server along with charging station ID. The portable transponder is registered with the internet server which includes transponder ID and associated vehicles or vehicle IDs. Once the request for payment authorization is received from the charging station by the server, the server verifies the information and approves or denies the request. Upon approval of the request, the charging can commence. The portable transponder can be used for charging a second vehicle, as long as the second vehicle is also registered with the server.

A vehicle service and a process to pay for the vehicle service are provided. A data connection is established between a service point and an electronic control unit of a vehicle. Initial vehicle service data is gathered that includes a timestamp of establishing the data connection, identification data of the vehicle, and, at the time of the timestamp, at least one value of a state of the vehicle indicating a quantity which is to be altered by the provision of the vehicle service. Service provider service data of the completed vehicle service is stored on the blockchain network. The validity of the provision of the vehicle service is checked by comparing the initial and final vehicle service data and the provider service data of the completed vehicle service. When the validity is confirmed, the process to pay for the vehicle service is triggered on the blockchain network.

The present invention provides a management system for managing a battery mounted on a vehicle, comprising: an acquisition unit configured to acquire rank information indicating a product rank set by a user as a reuse destination of the battery; and a notification unit configured to notify the user of restriction item information indicating an item for restricting a function of the vehicle such that a deterioration state of the battery at a predetermined time satisfies a request state of the product rank, based on the rank information acquired by the acquisition unit.

A vehicle receiving power from a ground power supplying apparatus by noncontact includes: a vehicle side first communication device for directly or indirectly communicating with the ground power supplying apparatus by utilizing wide area wireless communication; a vehicle side second communication device for directly communicating with the ground power supplying apparatus by utilizing short range wireless communication; and a control device for making the vehicle side first communication device transmit vehicle information tied with vehicle identification information to the ground power supplying apparatus and making the vehicle side second communication device transmit the vehicle identification information to the ground power supplying apparatus after the vehicle side first communication device transmits the vehicle information, when the vehicle receives power from the ground power supplying apparatus.

A charging rescue system and method for all-electric vehicles comprises: a rescue vehicle APP, a charging rescue vehicle, a rescued vehicle APP, and a rescue platform. The rescue vehicle APP comprises a user module, an order module, a monitoring module, and a communication module. The charging rescue vehicle comprises a controller, a GPS device, a direct current battery charger, an alternating current battery charger, and a measuring module. The rescued vehicle APP comprises a user module, an order module, a payment module, and a communication module. The rescue platform comprises an access module, an order execution module, a vehicle selection module, a rescue vehicle monitoring module, a bill management module, and a user authentication module.

A power electronics charge coupler (PECC) unit allows vehicle-to-vehicle (V2V) energy transfer by forming a bidirectional buck/boost converter for supplying rapid energy transfer with wide input-output battery voltage and battery voltage levels. The PECC unit embeds DC-DC converter modules into the charging handles of the PECC unit. Each of the charging handles includes a half-bridge of the DC-DC converter and parasitic inductance of a cable between charging handles is utilized as a portion of the filter inductor for the converter. The PECC unit handles are each configured to connect to an electric vehicle and are dynamically configurable in one of four modes of operation based on the battery voltage of the electric vehicles to which the PECC unit is connected and based on which of the electric vehicles is designated as the receiver vehicle and which is designated as the supplier vehicle.

A method for temperature control of a traction battery includes predefining a target temperature which the traction battery should have at the end of a journey and upon arrival at a fast-charging station; predicting a temperature which the traction battery will have at the end of the journey and upon arrival at the fast-charging station; determining a temperature difference between the target temperature and the predicted temperature; predefining a temperature control specification for temperature control of the traction battery during the journey of the motor vehicle to the fast-charging station in accordance with the determined temperature difference, so that the target temperature prevails upon arrival at the fast-charging station; and controlling the temperature of the traction battery according to the predetermined temperature control specification during the journey of the vehicle.

A power management system includes a plurality of power adjustment resources electrically connected to a microgrid MG, and a CEMS server that manages the power adjustment resources. The CEMS server outputs a power adjustment request to a plurality of power adjustment resources when suppression of power consumption or consumption of surplus power is requested in the microgrid MG, and gives an incentive to the power adjustment resource that performs power adjustment in response to the power adjustment request among the power adjustment resources. The CEMS server increases the incentive more as a deviation of a second power amount adjusted by a responding resource with respect to a first power amount requested for adjustment by the power adjustment request is smaller.

A power management system includes a plurality of power adjustment resources electrically connected to a microgrid MG, and a CEMS server that manages the power adjustment resources. The CEMS server outputs a power adjustment request to the power adjustment resources when suppression of power consumption or consumption of surplus power in the microgrid MG is requested, and gives an incentive to a “responding resource” as the power adjustment resource that performs power adjustment in response to the power adjustment request among the power adjustment resources. The CEMS server increases the incentive more as a deviation of a time period during which the power adjustment is performed by the responding resource, with respect to a time period determined in the power adjustment request is smaller.

An electric vehicle charging system includes logic collocated with an electric service panel to monitor a total present electric current consumption value for all electric consumers below a point in the service panel; a first input to receive the present electric current consumption value from the logic collocated with the service panel, and to compare the present electric current consumption value with a maximum current capacity value for the service panel; a second input to receive electric current from the service panel; an output to supply electric charging power to at least one electric vehicle; and logic to set an electric charging current drawn from the service panel through the second input and provided to the electric vehicle charging output to a value less than a difference between the maximum current capacity for the service panel and a sum of the present electric current consumption value and the current consumption value of a largest expected electric consumer.
