Abstract
In a vehicle drive system using a motor for cruising, the connection node of serially-connected first and second batteries is grounded. The operation of an inverter is controlled so that the motor drive voltage is higher than the output voltage of each of the first and second batteries. A balance circuit balances the charged amounts of the first and second batteries by performing charge/discharge control between the first and second batteries.
