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, and achieving smooth acceleration without any torque staying.SOLUTION: A contactor controller includes a calculation part 18 for calculating request torque based on an accelerator opening, and a control unit 19 for outputting a command for switching one of pluralities of positive-electrode side contactors and negative-electrode side contactors to an ON-state based on the requested torque and controlling an output current from a battery 20 to an inverter 21. The control unit 19 suppresses the output current according to the increased acceleration of the requested torque when the command is output.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し、トルク滞留のない滑らかな加速を実現することができる、コンタクタ制御装置を提供する。【解決手段】アクセル開度に基づいた要求トルクを算出する算出部18と、要求トルクに基づいて複数の正極側コンタクタ及び負極側コンタクタのいずれかをON状態に切り替える指令を出力すると共に、バッテリ20からインバータ21に対する出力電流を制御する制御部19と、を備え、制御部19は、前記指令を出力した際、要求トルクの増加速度に応じて出力電流を抑制する。【選択図】図1
