In creating a charging plan for an electric vehicle, calculation amount becomes enormous as the number of electric vehicles increases, leading to a problem of increasing the resources required for calculation. To solve this problem, the present disclosure includes a grouping unit configured to group a plurality of electric vehicles into an electric vehicle cluster based on a classification rule, a total charging power determination unit configured to determine total charging power of the electric vehicle cluster for each group for each time based on the restriction condition, and an individual charging power determination unit configured to determine individual charging power for each of the electric vehicles for each time based on the total charging power.

Various disclosed embodiments include illustrative direct current (DC) power electronics modules, charging systems, and methods. In an illustrative embodiment, a DC power electronics module includes an electronics component configured to provide DC power to at least a first battery and a second battery, a processor configured to communicate with the electronics component, and non-transitory computer-readable media configured to store computer-executable instructions. The stored instructions cause the processor to determine connection status of the first battery and the second battery to the DC power electronics module and instruct the electronics component and/or a connection device to allocate DC power to the first battery and the second battery responsive to the determination that the first battery and the second battery are connected to the DC power electronics module.

Systems and methods for a multi-vehicle charging station are provided. In one embodiment, a method includes identifying a charging station configured to provide a host vehicle a charge according a host vehicle charging schedule. The method also includes identifying a proximate vehicle based on a charging distance between the proximate vehicle from the charging station. The method further includes transmitting a cooperation request to the proximate vehicle. The method yet further includes receiving a proximate vehicle charging schedule from the proximate vehicle. The method includes generating a cooperative charging schedule based on a comparison of the host vehicle charging schedule and the proximate vehicle charging schedule. The method also includes transmitting the cooperative charging schedule to the charging station.

A vehicle is configured to carry out external charging operation in which an in-vehicle battery is charged with electric power from a device outside the vehicle. The vehicle includes the in-vehicle battery, a charger and a control device. The charger is configured to output electric power from the device outside the vehicle to the in-vehicle battery. The control device is configured to control the charger so that the external charging operation is completed by time set by a user. Furthermore, the control device is configured to preferentially allocate a period of time during which the external charging operation is carried out in order of a priority time period set by the user, an immediate time period immediately after the priority time period and a preceding time period immediately before the priority time period.

A non-contact power supply system supplies power in a non-contact manner between a power transmission coil of a power supply device and a power reception coil of a vehicle. The power supply device side communication unit transmits identification information of the power supply device to the vehicle. The generation unit generates a power pattern list by allocating each piece of the identification information that is received by the vehicle side communication unit to several power patterns based on a prescribed rule. The vehicle side communication unit transmits the power pattern list to the power supply device. The controller causes power to be outputted from the power transmission coil to the power reception coil according to a power pattern which corresponds to the identification information. The determination unit determines establishment of a paired communication based on a comparison the detected power pattern and a power pattern.

Embodiments of a method and/or system for charging one or more electric vehicles (e.g., based on one or more reserved charging sessions; for charging an electric vehicle during a scheduled time period; etc.) can include: receiving a reservation request (e.g., a reservation request including one or more reservation parameters; etc.); scheduling a reserved charging session based on the reservation request (e.g., based on reservation parameters from the reservation request; etc.); determining a check in at an Electric Vehicle Service Equipment (EVSE) for the reserved charging session; and/or causing the EVSE to charge the electric vehicle based on the reserved charging session (e.g., during the scheduled time period; etc.).

A vehicle includes a power reception unit receiving power from outside of the vehicle, a power storage device, and a control device performing control for charging the power storage device in accordance with a schedule set for timer charge. In the case where a charge time band of a first schedule defining a charge start time and a charge end time and a charge time band of a second schedule defining a charge start time and a charge end time overlap each other, the control device starts charge at the earlier one of the charge start time of the first schedule and the charge start time of the second schedule when the charge start times are different, and ends charge at the later one of the charge end time of the first schedule and the charge end time of the second schedule when the charge end times are different.

A charging system for a vehicle includes a connector suspended on a flexible cable and an adapter having a plug at a first end and an adapter port at a second end opposite the first end. The plug is removably disposed in a charging port of the vehicle and the adapter port extends outward from the vehicle. The connector is movable along a plurality of axes perpendicular to one another into a mated position with the adapter port.

The disclosure includes a system and method for providing charging services to mobile client devices. The system includes a processor and a memory storing instructions that, when executed, cause the system to: receive demand response event data associated with a geographic region; determine a last-mile distribution network that includes a first endpoint in the geographic region, the first endpoint associated with a mobile client device; estimate one or more last-mile power usage factors describing power usage of a set of endpoints in the last-mile distribution network, the set of endpoints including the first endpoint associated with the mobile client device; and determine a charge schedule for the mobile client device based on the demand response event data and the one or more last-mile power usage factors.

According to an embodiment, energy management system includes client and server. Server includes acquisition unit, estimation unit, calculator and controller. Acquisition unit acquires data concerning electrical equipment in a building including a storage battery from client. Estimation unit estimates energy demand and energy generation amount in building based on the data. Calculator calculates, based on the energy demand and the energy generation amount, operation schedule of the electrical equipment to optimize energy balance in building under a constraint that minimizes dump power to be discarded after storage battery is fully charged. Controller creates control information to control electrical equipment based on operation schedule.
