ある。When a dedicated battery is used as in the latter prior art described above, the battery has to be charged separately, which is troublesome to manage and is charged by an engine-driven generator. It is desirable to use a battery that can be used. However, when the battery for general electric components is used as in the former conventional technique described above, there is a problem that the battery voltage is significantly lowered when the wheels are started by the electric motor, and the power supply to the general electric components is hindered.

The present invention relates to a vehicle in which one of front and rear wheels is driven by an engine and the other is driven by an electric motor, and a main battery which is connected to a generator driven by the engine and which stores electric power for supplying general electric components and an electric motor. And a sub-battery that stores the electric power to be supplied to the main battery, and the resistance value of the wiring circuit between the two batteries is better than the resistance value of the wiring circuit between the sub-battery and the electric motor. The feature is that it is set large.

バッテリーの電圧が低下することはない。The sub-battery is charged by the generator together with the main battery, and the electric power is supplied from the sub-battery to the electric motor when the wheels are activated by the electric motor. At this time, the power supply from the main battery is restricted because the resistance value of the wiring circuit between the battery and the sub battery is larger than the resistance value of the wiring circuit between the sub battery and the electric motor, and the voltage of the main battery is It does not drop significantly. When the voltage of the sub-battery drops after the wheels are activated, the electric power is also supplied from the main battery to the electric motor, but after the activation, the load on the electric motor is reduced, so that the voltage of the main battery does not decrease.

小さくなる。The load on the electric motor 5 becomes the largest when the rear wheels 2 are started, and when electric power is supplied to the electric motor 5 only by the main battery 8 at this start, the voltage V of the main battery 8 is increased.
Is greatly reduced at the time of start-up, as indicated by the line b in FIG. However, in this embodiment, as described above, the resistance value of the wiring circuit 14 between the main battery 8 and the sub battery 9 is set to be larger than the resistance value of the wiring circuit 13 between the sub battery 9 and the electric motor 5. Therefore, power is mainly supplied from the sub-battery 9 to the electric motor 5 at the time of startup. For example, if the resistance value of the wiring circuit 14 is set to be 2.7 times the resistance value of the wiring circuit 13, the power consumption of the main battery 8 and the sub-battery 9 are reduced. The ratio to the power consumption is 1: 2, and the voltage drop of the main battery 8 at the time of start-up becomes small as shown by the line a in FIG.
