Provided is an electronic device for managing energy with a simplified button operation, and an operating method thereof. The method of operating the electronic device includes displaying a charging time, which is required for charging completion of a charging target load device that a user desires to charge, and a charging demand, which is required for charging, by using a profile related to energy use of the user, receiving, from the user, an increase command, a determination command, or a decrease command, and when a received command is the increase command or the decrease command, performing an increase or a decrease in one of the charging time and the charging demand or the combination of two or more thereof, according to the increase command or the decrease command, based on an increase rate or a decrease rate using a change rate calculated through a change rate calculation model.

An electrified vehicle includes a controller programmed to implement performance mode control of first and second electric machines and wheel brakes associated with wheels of respective first and second axles to provide a braking force to a first axle while providing torque to the second axle to intentionally spin the tires of the second axle to provide a peelout and associated heating or smoking of the tires to improve traction and provide a visual display of power. The maneuver may be repeated for the first axle by providing torque to the first axle while applying braking force to the second axle. A sequential maneuver that spins tires of the first axle followed by tires of the second axle may be performed by specified manipulation of the brake pedal and accelerator pedal.

A server receives, from a certain house having power outage among a plurality of houses, supply request information about a request for an electric power supply to the certain house, retrieves, with reference to a database associating the houses with a plurality of electric vehicles configured to supply electric power respectively to the houses, a candidate electric vehicle that enables the electric power supply to the certain house among the electric vehicles associated with other houses different from the certain house, transmits, to a terminal associated with the retrieved candidate electric vehicle, cooperation request information about a request for the electric power supply from the candidate electric vehicle to the certain house, and transmits, when receiving from the terminal reply information indicating acceptance of the electric power supply to the certain house, location information about a location of the certain house to the terminal.

Methods and systems are disclosed configured to charge an electrical vehicle. A charge request is received for a first electrical vehicle parked at a first parking spot. A battery charging device is connected to a first head unit comprising a first charging cable located in proximity to the first parking spot. A charge request is received for a second electrical vehicle parked at a second parking spot. A determination is made as whether the first electrical vehicle is no longer being charged, and in response to determining that the first electrical vehicle is no longer being charged, the battery charging device is disconnected from the first head unit and is connected to a second head unit comprising a second charging cable located in proximity to the second parking spot.

A battery system for an electric vehicle includes a first battery module with a first heater and a second battery module with a second heater. The battery system also includes a control system configured to selectively activate the first or the second heater to dissipate energy from the first or the second battery module.

Methods and systems for activating electric vehicles are provided. One method includes, in response to a first command to activate the vehicle, transitioning the vehicle from an inactive state to a wake state where a controller of the vehicle is activated and the vehicle is prevented from being propelled by an electric motor of the vehicle. The method also includes, in response to receiving a second command to activate the vehicle after receiving the first command, transitioning the vehicle from the wake state to a ready state where the vehicle is permitted to be propelled by the electric motor.

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 system and method for recovering an output of a fuel cell is provided. The system and method for recovering an output of a fuel cell includes: an output recovering device connected to a fuel cell stack through at least one coolant heater line; and a vehicle controller configured to communicate with the output recovering device and control supply of a coolant, air, and hydrogen to the fuel cell stack. The output recovering device also includes a current supplier configured to supply a current to the fuel cell stack and a controller configured to communicate with the vehicle controller and control the current supplied from the current supplier.

Methods and systems for activating electric vehicles are provided. One method includes, in response to a first command to activate the vehicle, transitioning the vehicle from an inactive state to a wake state where a controller of the vehicle is activated and the vehicle is prevented from being propelled by an electric motor of the vehicle. The method also includes, in response to receiving a second command to activate the vehicle after receiving the first command, transitioning the vehicle from the wake state to a ready state where the vehicle is permitted to be propelled by the electric motor.

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.
