To provide an authentication device, an authentication system, and an external device which are not affected by noise generated at the time of supplying power while maintaining security when supplying power to a power storage device.SOLUTION: An ECU 110 (Authentication device) includes a communication unit which performs, using a first communication frequency or a second communication frequency, communication with an external device 200 provided separately from a vehicle 100, and a control unit which determines whether the authentication of the external device 200 is established. When no power is supplied to a battery 420 through components provided in a casing, the control unit causes the communication unit to perform communication for authentication of the external device 200 using the first communication frequency to determine authentication with the external device 200, and when power is supplied, causes the communication unit to perform communication for authentication of the external device 200 using the second communication frequency and determines authentication with the external device 200 on the basis of the position information of the external device 200.SELECTED DRAWING: Figure 1

    【課題】蓄電装置への給電時に、セキュリティ性を保ちながら給電の際に発生するノイズの影響を受けない認証装置、認証システムおよび外部装置を提供する。【解決手段】ECU110(認証装置)は、車両100と別に設けられる外部装置200との間で第1通信周波数または第2通信周波数を用いて通信を行う通信部と、外部装置200の認証成立を判定する制御部と、を備える。制御部は、筐体に設けられた部品を介したバッテリ420への給電が行われていない場合には、通信部により第1通信周波数を用いて外部装置200の認証のための通信を行わせて外部装置200との認証成立を判定し、給電が行われている場合には、通信部により第2通信周波数を用いて外部装置200の認証のための通信を行わせるとともに、外部装置200の位置情報に基づいて、外部装置200との認証成立を判定する。【選択図】図1
