A vehicle includes an engine, a rotary electric machine, an electric storage device, and a controller. The rotary electric machine is connected to an output shaft of the engine. The electric storage device is configured to supply electric power to a drive source of the vehicle and to be charged with electric power from an external power source. The external power source is disposed outside the vehicle. The controller is configured to supply the electric power from the external power source to the rotary electric machine such that the output shaft is rotated when the electric storage device is chargeable with the electric power from the external power source.

A system and method is provided for controlling electric power in a plug-in vehicle, such as a pure electric vehicle or hybrid electric vehicle. The electric power is controlled from an external power source to one or more predetermined components in the plug-in vehicle. The power source is external to the vehicle and has a maximum power level. Electric power at a charging level from the external power source is received. Based on the charging level and the maximum power level, an available power level is determined. Based on the available power level, the electric power is controlled from the external power source to the predetermined components in the plug-in vehicle.

To create a charging/discharging plan when a vehicle including a storage battery is chargeable/dischargeable at a plurality of facilities. An energy management system includes a schedule management unit configured to manage a schedule for moving from a first facility to a second facility, and a charging/discharging plan creation unit configured to create a first charging/discharging plan being a charging/discharging plan for a storage battery in each of the first facility and the second facility, in which the charging/discharging plan creation unit is configured to create the first charging/discharging plan with which the storage battery discharges at the first facility while leaving moving power being power for the vehicle to move from the first facility to the second facility.

A method is described for operating a motor vehicle which is driven with the aid of an electric machine, the electric machine being supplied with electrical energy from an energy store which is charged by an external energy source. To ensure that the driver receives the information concerning readiness for continued travel of the vehicle at the point in time when sufficient energy is present in the energy store in order to reliably reach the intended destination or to cover a predetermined route, the motor vehicle is notified of a destination and/or a route, and the motor vehicle is connected to the external energy source for charging the energy store, the motor vehicle outputting information as to when the energy store has been charged with sufficient energy to reach the destination or to cover the route, and the driver stopping at a next charging station in particular after having reached the destination or having covered the route.

A computer-implemented method for scheduling pre-departure charging for electric vehicles includes predicting a user-departure time based on a first machine learning prediction model. The method further includes determining a cabin temperature to be set for the user at the user-departure time based on a second machine learning prediction model. The method further includes determining a battery-temperature to be set at the user-departure time based on a third machine learning prediction model. The method further includes determining a present charge level of a battery of the electric vehicle. The method further includes computing a charging start-time to start charging the battery based on one or more attributes of a charging station to which the electric vehicle is coupled, and based on the user-departure time, the cabin temperature, and the battery-temperature. The method further includes initiating charging the battery at the charging start-time.

A charge system for a vehicle includes a traction battery and a controller. The controller, responsive to passage of a predetermined period of time following activation of the vehicle without detecting a wake up signal, sets a diagnostic flag. The controller further, responsive to deactivation of the vehicle, presence of the diagnostic flag, and presence of a request designating a future start time for a charge event of the traction battery, initiates the charge event regardless of the future start time. The controller may further, responsive to deactivation of the vehicle, absence of the diagnostic flag, and presence of the request designating the future start time for the charge event of the traction battery, inhibit start of the charge event until the future start time.

A vehicle control system may, during a deactivated state of the vehicle, generate a wake up signal, and responsive to a current or voltage associated with the wake up signal being outside a predetermined range, activate an ignition relay of the vehicle for a predefined period of time. The vehicle control system may further, responsive to a request to activate the vehicle, activate the ignition relay.

A system and method for early identification of an impending fast-charge or fast-charge opportunity and use of that information to prepare the battery cells for the fast-charge.

A charging system for a multi-floor tower for the parking of electric vehicles includes a super capacitor, a charging port connecting with the electric vehicle, and a charging controller. The charging controller includes a diverter switch, a first current limited portion, a second current limited portion, and a charging control portion. The charging control portion is connected with the diverter switch, the super capacitor, and the charging port. The first current limited portion outputs a first stable current and is interconnected between the diverter switch and the charging port. The second current limited portion outputs a second stable current and is interconnected between the super capacitor and the charging port. The magnitude of the first stable current is larger than the magnitude of the second stable current.

In a server, an acquisition unit obtains, from a vehicle through a communication apparatus, history information indicating that demand and supply of electric power has been performed for a power grid PG, and information on the state of charge of a battery. A control unit determines priorities of a plurality of DERs for a DR request. The control unit determines a priority of the vehicle so that the vehicle is less likely to be selected for the DR request, when the SOC obtained by the acquisition unit has changed although the acquisition unit has not received the history information.
