A mobile charging station for a high voltage electric vehicle including a mobile vehicle for transporting charging apparatus. The charging apparatus includes an electric energy source for providing electricity, a circuit for converting the energy source electricity to a specific voltage range required by the electric vehicle to be charged and at least one connector engageable with a charging connector on the electric vehicle to be charged. The mobile charging station may be driven to the location of the electric vehicle. A vehicle charge may be initiated by a communication sent from a cellular device or a mobile communication device. The mobile charging station may include a remote command center capable of receiving communication from a consumer and remotely initiating a service call to the consumer or an automatic battery health and safety check system to ensure the battery is not leaking, or over heated to prevent vehicle fire.

An embodiment charging control method of an electric vehicle includes receiving, by a head unit of the electric vehicle, input of order information for a charging station, requesting payment based on the order information, and opening a charging port door when charging approval information is received in response to order identification information corresponding to the order information being input to a charger provided in the charging station.

Techniques are presented for scheduling the charging of electric vehicles (EVs) that protect the resources of local low voltage distribution networks. From utilities, data on local low voltage distribution networks, such as the rating of a distribution transformer through which a group of EVs are supplied, is provided to a load manager application. Telematics information on vehicle usage is provided from the EVs, such as by way of the original equipment manufacturer. From these data, the load manager application determines schedules for charging the group of EVs through a shared low voltage distribution network so that the capabilities of the local low voltage distribution network are not exceeded while meeting the needs of the EV user. Charging schedules are then transmitted to the on-board control systems of the EVs for implementation.

A server apparatus includes a communication interface and a controller configured to communicate using the communication interface. The controller is configured to receive, from a vehicle driven by electricity from a battery, operation information on operation of the vehicle, transmit, to the vehicle or a charging/discharging apparatus, information on a charging/discharging plan for charging the battery with predetermined electricity purchased by a community, the charging/discharging plan including a charging/discharging timing for the vehicle and a charging/discharging location within the community based on the operation information, and control the vehicle or the charging/discharging apparatus to execute the charging/discharging plan.

A power management system includes a vehicle and a charging or discharging lane. The charging or discharging lane configured to execute at least one of charging or discharging of the vehicle in a non-contact manner. The vehicle is configured to acquire contract contents including a charging or discharging amount and a charging or discharging period. The vehicle is configured to execute the contract contents in a charging or discharging lane that is different from electric vehicle supply equipment set in the contract contents and is reachable before the charging or discharging period when the vehicle is predicted to, before a start of the charging or discharging period, be unable to execute the contract contents in the set electric vehicle supply equipment.

An information processing device according to the present application includes a hardware processor functioning as an acquisition unit, a determination unit, and a provision unit. The acquisition unit acquires user information that is information relative to a user. The determination unit determines a recommended battery on the basis of the user information acquired by the acquisition unit. The recommended battery is recommended to the user and used for a moving object. The provision unit provides information relative to the recommended battery determined by the determination unit.

Systems and methods are provided herein for charging an electric vehicle based on the inferred dwell time of a user of the electric vehicle. This may be accomplished by an electric vehicle charging station (EVCS) receiving a request from a user to charge an electric vehicle. The EVCS can use the request to identify a profile associated with the user, wherein the profile comprises user information related to the user. The EVCS then estimates a dwell time for the user using the user information. The EVCS can use the dwell time to estimate a total charge time for the electric vehicle. The EVCS then charges the electric vehicle based on the estimated charge time.
