According to one embodiment, there is provided a charging management system including a display controller configured to cause a display device to display a time slot which is settable as a new desired rental time slot of an electric vehicle, based on a charging time slot on an assumption that charging to the vehicle by a second charging device is performed, and a scheduling module configured to set the desired rental time slot as a time slot in which rental is possible, if the charging to the electric vehicle for enabling the rental is possible in the input desired rental time slot and the rental time slot in which the rental reservation has been made.

Systems, methods, and apparatus embodiments for electric power grid and network registration and management of physical and financial settlement for participation of active grid elements in supply and/or curtailment of power, wherein Internet Protocol (IP)-based messages including IP packets are generated by transforming raw data content into settlement grade content. Settlement is provided for grid elements that participate in the electric power grid following initial registration of each grid element with the system, preferably through network-based communication between the grid elements and a coordinator, either in coordination with or outside of an IP-based communications network router. Messaging related to settlement is managed through a network by a Coordinator using IP messaging for communication with the grid elements, with the energy management system (EMS), and with the utilities, market participants, and/or grid operators.

A vehicle configured to communicate with a server of a cloud system to enable access to use the vehicle via one or more electronic keys is provided. The vehicle includes electronics and a subsystem of the vehicle for enabling unlocking of the vehicle. The subsystem is interfaced with the electronics and a subsystem of the vehicle for enabling starting of the vehicle for use of the vehicle. The vehicle further includes communications circuitry that is interfaced with electronics of the vehicle. The communications circuitry is programmable to communicate with the server of the cloud system and communicate with a mobile device. The communications circuitry of the vehicle is configured to receive a request from the mobile device for unlocking of the vehicle. The request from the mobile device includes a unique access code obtained by the mobile device from the server to enable sending the request to the vehicle. The unique access code is associated with privileges for use of the vehicle. The privileges are defined for the unique access code, and the vehicle is configured to receive information from the server to authenticate the request by the mobile device. And, if the request is authentic, the mobile device is provided with data to enable an electronic key to use the vehicle, and the electronics of the vehicle instructs the subsystem of the vehicle to enable unlocking of the vehicle and enable starting of the vehicle for use of the vehicle via the electronic key consistent with the privileges of the unique access code.

Methods and systems for charging vehicles in a parking area are described. In one embodiment, a charge request may be received for a vehicle located in a parking area. The vehicle may have a power connection with a power source. An electric charge is provided through the power connection from the power source to the vehicle based on receiving the charge request, the value of the electric charge being adjustable based at least in part on the power basis of the vehicle. Billing or Payment is recorded for providing the electric charge based upon departure of the vehicle from the parking area.

A method of processing a transaction includes receiving a site location code. Site configuration information corresponding to the received site location code is received from a database. That information includes more product record(s), each corresponding to a reservable product or a non-reservable product. A selection of one or more of the product records in the retrieved information is received. If any selected product record corresponds to a reservable product, a reservation command is produced. That command requests reservation of selected reservable product(s). A method of selecting a product includes receiving a location input and determining a site location code with it. The site location code is transmitted and one or more product records are received. Representations of one or more of the received product records are presented and a selection of products is received. An indication of the selection is transmitted.

Two-way exchange vending can be performed by a two-way exchange based vending machine. The two-way exchange based vending machine can vend rechargeable batteries. The two-way exchange based vending machine can include different modules to perform different functionalities. The two-way exchange based vending machine can include a communications module, a dispensing module, a rejection module, and a receiving module. The communications module can communicate information to and receive inputs from a user. The dispensing module can dispense one or more rechargeable batteries or other requested products to a user. The receiving module can receive one or more rechargeable batteries from a user.

A multiplicity of participants comprising utility operators, distributed energy resource (DER) providers, vendors/aggregators, energy customers, and utility financial officers, are communicatively connected to a platform. The platform provides interactive interfaces for each type of participant to access the platform over communication network. Utility operators are enabled to view and control DER in a certain area via an interface for utility operators. DER providers are enabled to interconnect DER packages to a utility grid via an interface for DER providers. Vendors/aggregators are enabled to view and manage their portfolios via an interface for vendors/aggregators. Energy customers are enabled to view energy information, shop for new products or services, and manage rate plans via an interface for marketplace. Utility financial officers are enabled to view revenue streams from the platform to a utility via an interface for financial settlement.

In some embodiments, the system and method may access a request to charge an electric vehicle at a specific charging station, identify a charging network (e.g., one of multiple, disparate charging networks) associated with the specific charging station, and automatically provide payment information to the charging network via a payment protocol associated with the charging network. The charging interface system, therefore, may facilitate access to any charging network and/or charging station by providing an interface between a driver of an electric vehicle and one of many charging networks.

An off-grid renewable energy harvesting device is disclosed, which provides electric power for purchase for general devices and for authenticated devices. In some embodiments only authenticated devices may be provided with electricity for purchase. In certain embodiments the authenticated devices may be provided electric power at a rate different than general devices. In some embodiments, secondary services may be provided by the authenticated devices. Secondary services may be providing communication, providing internet and internet-related services, video-on-demand services, digital video broadcasting, and the like.

Herein is disclosed a vehicle-to-vehicle charge transfer system, comprising a charging cable, configured to connect a first electric vehicle to a second electric vehicle; and a donation control unit, configured to receive one or more vehicle charge transfer parameters from the second vehicle; and transfer an electric charge from the first electric vehicle to the second electric vehicle along the charging cable according to the one or more received vehicle charge transfer parameters.
