Power supplying device, charging device, power supplying method, and power supplying program

Abstract

Provided are a power supplying device and a charging device having a configuration by which cost can be reduced even in a facility capable of wirelessly supplying power to a plurality of vehicles, and also provided are a power supplying method and a power supplying program. The power supplying device comprises power supplying units and power supplying control units. The power supplying units wirelessly supply powers to charging devices mounted on vehicles. The power supplying control units receive vehicle detection information from a sensor that transmits the vehicle detection information when detecting vehicles, and control the power supplying units provided in the power supplying device to supply first power specified for each power supplying device and used for identifying the power supplying device. When receiving, from the charging devices, power supplying unit identifying information having information indicating power levels received from the power supplying units, the power supplying control units transmit charging start information indicating the start of charging to the charging devices when it is determined that the received power levels are within a specified power range indicating a specified power level range stored in a storage unit, and control the power supplying units to supply second powers in order to charge battery units in the charging devices.

Description

technical field [0001] Embodiments discussed herein relate to a power feeding device, a charging device, a power feeding method, and a power feeding program configured to perform contactless power feeding. Background technique [0002] Recently, non-contact power feeding using electromagnetic induction is known as a charging system for vehicles such as electric vehicles (EV) and plug-in hybrid vehicles. [0003] In the non-contact power feeding, it is assumed to include a sensor or a radio unit that detects that the vehicle is parked to specify a feeding unit for supplying power to the vehicle when the vehicle is parked at a predetermined position in the power feeding device. Therefore, the power feeding equipment must include a sensor, a radio unit, etc., which leads to an increase in cost. [0004] In addition, a communication device using a signal transmission coil provided separately from a power transmission coil and a power reception coil is disclosed (for example, Pa...

AI Technical Summary

Problems solved by technology

Therefore, the power transmission coil and its periphery become complicated in configuration, which results in expensive power feeding equipment and charging equipment

[0006] In addition, in a facility in which electric power is fed to a plurality of vehicles adjacent to each other (for example, a charging station), it is necessary to provide the same number of feeding units and accompanying signal transmission coil communication means as the number of feeding devices, which leads to an increase in cost
