To provide a vehicular drive system using a traveling motor in which the output of the motor is increased and the potential of the system is sufficiently exerted, while suppressing increases in vehicle weight and costs.SOLUTION: In batteries Batt1 and Batt2 connected in series, connection nodes are connected with connection nodes of capacitors A and B of an inverter 15a. The inverter 15a is controlled in operation so as to make motor drive voltage higher than the output voltage of each battery Batt1, Batt 2. A balance circuit 30 balances the voltage of the capacitors A and B by performing charge/discharge control between the batteries Batt1 and Batt2.SELECTED DRAWING: Figure 8

    【課題】走行用モータを利用する車両用駆動システムにおいて、車両重量やコストの増大を抑制しつつ、モータを高出力化し、かつ、当該システムが持つポテンシャルを十分に発揮させる。【解決手段】直列に接続されたバッテリBatt1,Batt2は、接続ノードが、インバータ15aが有するコンデンサA,Bの接続ノードと接続されている。インバータ15aは、モータ駆動電圧が各バッテリBatt1,Batt2の出力電圧よりも高くなるように、動作が制御される。バランス回路30は、バッテリBatt1,Batt2間の充放電制御を行うことによって、コンデンサA,Bの電圧をバランスさせる。【選択図】図8
