摘要： The method for transmitting power wirelessly according to an embodiment may comprise checking a position of a receiving device while wirelessly transmitting power to the receiving device, and changing a charging stop level which is compared with power loss which corresponds to a difference between transmitted power transmitted to the receiving device and received power received by the receiving device when the receiving device is outside a charging area. The receiving device is outside the charging area may be determined based on that the received power is equal to or greater than reference power and a power control level when transmitting the power to the receiving device is equal to or greater than a reference value. The charging stop level may be returned to an original value when the power loss is lower than the changed charging stop level until a predetermined time elapses after changing the charging stop level.

摘要： A power supply system includes a vehicle equipped with a battery, a power supply device, and a control device that controls power supply from the power supply device to the vehicle. The vehicle includes an engine and a motor that receives the power supplied from the battery to generate traveling drive force. When the power supply by the power supply device is requested from the vehicle, the control device (a) acquires a remaining amount of fuel for the engine from the vehicle, (b) outputs an instruction to urge the vehicle to shorten a charging time when the remaining amount of fuel is larger than a reference value, and (c) sets at least one of a unit price for charging power or a unit price for fuel lower when a response to accept the instruction is received from the vehicle compared with when the instruction is not accepted.

摘要： Subscription-based electric vehicle charging management methods and systems are provided. A server receives charging request with at least a user identification code from an electric vehicle charging station or a mobile device through a network. The server searches a database according to the user identification code to obtain contract situation corresponding to the user identification code and determines whether the contract situation is in a contract expiration status or an arrears unpaid status. When the contract situation is not in the contract expiration status or the arrears unpaid status, the server instructs the electric vehicle charging station to perform a charging operation. When the contract situation is in the contract expiration status or the arrears unpaid status, the server transmits a charging rejection instruction to the electric vehicle charging station. In response to the charging rejection instruction, the electric vehicle charging station rejects the charging request.

摘要： An electronic device can include a power system including a battery and a processor programmed to detect connection of an external power source to the electronic device, determine an estimated disconnection time at which the external power source is expected to be disconnected from the electronic device, analyze power grid data corresponding to the external power source to identify one or more desired battery charging intervals and one or more undesired battery charging intervals prior to the estimated disconnection time, and operate the power system to charge the battery from the external power source during the identified one or more desired battery charging intervals and inhibit battery charging during the one or more undesired battery charging intervals. The processor can be programmed to inhibit battery charging by reducing the rate at which the battery charges or by preventing battery charging.

摘要： A system and method of planning external electric power usage of a vehicle traction battery includes retrieving, remotely from the vehicle, data including a current charge level of a traction battery in the vehicle and an estimated range of the vehicle based on the charge level. Input of planned power usage of the traction battery by a set of devices is input remotely from the vehicle. An estimated change of the current charge level is determined based upon the planned power usage based on the current charge level, the estimated range, and the planned power usage. Based on the estimated change of the current charge level, a revised charge level of the traction battery and a revised estimated range of the vehicle is determined, and the revised charge level of the traction battery and the revised estimated range of the vehicle is output to a user computing device.

摘要： A power transmitting device includes a power transmission unit using contactless power supply, processing circuitry configured to switch a power transmission mode of the power transmission unit between a normal output mode and a limit mode, and a transmission-side communication unit configured to execute communication with a power receiving device. The processing circuitry is configured to determine whether the power receiving device is a registered power receiving device based on information related to the power receiving device obtained from the transmission-side communication unit, determine whether the registered power receiving device is located inside a power transmission range of the power transmission unit, set the power transmission mode to the normal output mode when determining that the registered power receiving device is located inside the range, and set the power transmission mode to the limit mode when determining that the registered power receiving device is not located inside the range.
