Abstract

The driving system of the vehicle consists of a combustion engine 1 driving a generator 2. The generator charges the battery 3 and may also drive the motor 4 when the car is in motion. The motor drives the wheels of the vehicle. The control unit 5 sets the input parameters of the engine and generator in such a way as to achieve their maximum efficiency coefficient. When the battery is discharged, the control unit 5 switches on the engine 1 and generator 2. After the battery 3 has charged, the engine 1 will be switched off by the control unit 5 and the motor 4 will be driven by the battery 3. When the car is standing, the battery can be charged from a.c. mains, and this way the car can be used for short trips without using the combustion engine to charge the battery. <IMAGE>

Description

SPECIFICATION Electric vehicle driven by battery and generator This invention relates to motor vehicles.
The efficiency coefficient of the combustion engine depends on its revolution per time unit. The electric motor has not got this disadvantage. The range that a battery driven electric car can go without re-charging is limited by the capacity of the battery. The small range of this car is its disadvantage.
An electric car driven by a battery and having also a generator will not have the above mentioned disadvantages.
The combustion engine-generator unit will work with maximum efficiency coefficient. After the battery is charged the engine will be switched off and the car will be driven from the battery. After the battery is discharged the engine will be switched on again to charge the battery and drive the car as well.
Another advantage of this car is that the battery can be charged from a.c. mains and this way the car can be used for short trips without using the engine-generator unit to charge the battery.
With the advent of this type of car exhaust pipe smoke free zones could be introduced where necessary. The cars would enter the zones with fully charged batteries and would not be allowed to use combustion engines there.
The driving system of the car consists of a combustion engine 1 (Figure 1) driving a generator 2. The generator charges the battery and also drives the motor 4 when the car is in motion. The control unit 5 measures the current of the generator and the battery and switches on and off the engine and the generator. It also sets the input parameters of the engine and generator in such a way as to achieve their maximum efficiency coefficient.
When the battery is discharged the control unit 5 switches on the engine 1 and generator 2. After the battery 3 is charged the engine 1 and generator 2 will be switched off by the control unit 5 and the motor will be driven by the battery 3.
The generator and motor can be either d.c. or a.c.
In case of the a.c. generator a rectifier (not shown) must be used to charge the battery. In case of the a.c.
motor a d.c.-a.c. converter (not shown) must be connected between the battery and the motor.
1. A vehicle driving system is claimed, consisting of an internal or external combustion engine driving one or more d.c. or a.c. generators. The generator charges one or more batteries. The battery drives one or more motors. The motor drives one or more wheels of the vehicle. The vehicle driving system is characterized by the engine-generator unit working with maximum efficiency coefficient.
2. A vehicle driving system as claimed in Claim 1 characterized by the control unit switching off the engine automatically after the battery is charged and switching it on when it is discharged.
3. A vehicle driving system as claimed in Claim 1 characterized by a non-automatic switch to operate the engine.
4. A vehicle driving system consisting of more than one driving systems as claimed in Claim 1,2 and 3.
