PROBLEM TO BE SOLVED: To provide a contactor controller capable of suppressing power consumption necessary for holding the ON-state of a contactor on an electric circuit between a motor and an inverter in an electric vehicle.SOLUTION: A contactor controller includes a plurality of positive-electrode side contactors 11 to 13 arranged in parallel to one another on the positive-electrode side of an electric circuit between a battery 20 and an inverter 21 included in an electric vehicle and different from one another in capacity, negative-electrode side contactors 14 to 16 arranged in parallel to one another on the negative-electrode side of the circuit and respectively corresponding to the positive-electrode side contactors 11 to 13, and an ECU 17 for controlling connection/disconnection of the positive-electrode side contactors 11 to 13 and the negative-electrode side contactors 14 to 16 so as to set the minimum necessary numbers of positive-electrode side contactors and negative-electrode side contactors in a connected state according to the value of a current flowing through the circuit.SELECTED DRAWING: Figure 1

    【課題】電動車両におけるモータ‐インバータ間の電気回路上のコンタクタの、ON状態を保持するために必要な消費電力を、抑制することを可能とする、コンタクタ制御装置を提供する。【解決手段】電動車両に備わるバッテリ20とインバータ21間の電気回路の正極側に互いに並列に配設され、互いに異なる容量である、複数の正極側コンタクタ11〜13と、前記回路の負極側に互いに並列に配設され、正極側コンタクタ11〜13にそれぞれ対応する、複数の負極側コンタクタ14〜16と、前記回路を流れる電流値に応じて、必要最小限の正極側コンタクタ及び負極側コンタクタを接状態とするように、各正極側コンタクタ11〜13及び各負極側コンタクタ14〜16の接断を制御するECU17とを備える。【選択図】図1
