発明の名称: (EN) Non-contact power supply system and power transmission device
(ZH) 非接触供电系统和送电装置
要約: front page image
(EN) A non-contact power supply system is provided with: a power transmission device (10c) that comprises a power transmission coil (14); and a power reception device (40) that comprises a power reception coil (41). Power is transmitted in a non-contact manner from the power transmission coil (14) to the power reception coil (41), and power is supplied to a battery (44) that is mounted to the power reception device (40). The power reception device (40) comprises a first efficiency calculation unit (55) that calculates a first efficiency from a transmitted power command value and the power that is supplied to the battery (44). The power transmission device (10c) comprises: a second efficiency calculation unit (31) that calculates a second efficiency from the phase difference between the voltage and the current that are supplied to the power transmission coil (14); and a control amount calculation unit (29) that controls the power that is supplied to the power transmission coil (14) on the basis of the transmitted power command value and limits the power that is supplied to the power transmission coil (14) when the first efficiency becomes equal to or less than a preset first threshold efficiency or when the second efficiency becomes equal to or less than a preset second threshold efficiency.
(ZH) 具备具有送电线圈(14)的送电装置(10c)、具有受电线圈(41)的受电装置(40)。而且,以非接触的方式从送电线圈(14)向受电线圈(41)输送电力,向搭载于受电装置(40)的电池(44)供给电力。受电装置(40)具有基于送电电力指令值和向电池(44)供给的供电电力来运算第一效率的第一效率运算部(55)。送电装置(10c)具有基于向送电线圈(14)提供的电压与电流的相位差来运算第二效率的第二效率运算部(31)。还具有控制量运算部(29),该控制量运算部(29)根据送电电力指令值来控制向送电线圈(14)供给的电力,并且在第一效率为预先设定的第一阈值效率以下的情况下、或者在第二效率为预先设定的第二阈值效率以下的情况下,抑制向送电线圈(14)供给的电力。
