Description

DESCRIPTION
BATTERY DRIVEN VEHICLE
The present invention relates to vehicle and in particular to wheeled vehicles which arc powered by one or more onboard electric batteries.
In conventional vehicles having petrol/diesel engine, the battery or batteries contained on board the vehicle are used to provide electrical energy to drive the many onboard electrical systems, such as lighting heating, wipers, radio etc. The battery is maintained in a substantially constantly fully charged state by means of an alternator or dynamo driven by engine. Thus the energy required to keep the battery in a charged state, comes directly from the engine itself.
Conventional electric road vehicles have an electric motor as a power source that uses one or more batteries or fuel cells as the source of energy. The batteries need to be recharged regularly from an external power source. So-called hybrid vehicles usually have different power sources to drive the vehicle, the most popular combination being an internal construction engine having petrol or diesel fuel and an electric motor powered by one or more rechargeable batteries.
Both electric vehicles and hybrid vehicles often have some form of regenerative braking system which converts vehicle kinetic energy into electrical energy to recharge the batteries when the vehicle is undergoing braking, the braking force being used to drive the electric motor of the vehicle so that this operates as a generator, or drives a separate generator, that is used to generate an electric current to recharge the batteries. The electric energy produced by the regenerative system is stored in the vehicle batteries and is used, when required, to drive the vehicle electric motor.
However, hybrid engines still have a requirement that an internal combustion engine is needed for driving the vehicle for at least some of the time, with its attendant requirement for a fuel such as petrol or diesel to be supplied to and carried by the vehicle It is an object of the present invention to provide an improved battery driven vehicle which operates with battery power alone.
In accordance with one aspect of the present invention there is provided a non-hybrid vehicle having a plurality of wheels on which the vehicle travels, at least one of which wheels is arranged to be driven by an electric motor using energy supplied by one or more onboard rechargeable batteries, a generator driven by at least one of the vehicle wheels to supply an electric current to charge the battery and a control system adapted to control the supply of current from the generator to the one or more batteries and from the one or more batteries to the electric motor or motors.
Preferably, there are at least two batteries, or battery sets, one which is arranged to be used for driving the electric motor at a given time and the other of which is to be charged via the generator, the battery roles being arranged to be reversed by the control system when the battery used to charge the motor has been discharged to a predetermined level.
Preferably, each of the front wheels has a respective electric motor associated with it. In other embodiments, some or all vehicle wheels can have associated electric motors.
Preferably, the generator is driven by the rear wheels of the vehicle and is situated intermediate these wheels and coupled to the wheels via respective axles.
In accordance with a second aspect of the present invention there is provided a vehicle having electric-only drive and comprising a plurality of travel wheels, at least one of which is arranged to be driven by an onboard electric motor, at least one generator driven by a travel wheel of the vehicle to generate an electric current when the wheel rotates, and at least two batteries, or battery sets, one of which is selected by a control system ol the vehicle for driving said electric motor and the other of which is selected for charging by said generator current, the control system being arranged to selectively interchange the roles of the two batteries during operation in accordance with the operational state of charge of one or both of the batteries.
The invention is described further hereinafter, by way of example only, with reference to the accompanying drawing which shows in a highly diagrammatic and simplified maimer one possible embodiment of a battery driven vehicle in accordance with the present invention.
In the drawing, the reference numeral 10 denotes the chassis/body of a vehicle, in this case a multi-wheeled road vehicle such as a car or truck. In principle, however, the vehicle can be any battery-driven wheeled vehicle.
The illustrated vehicle has four road wheels 12, the right hand pair as viewed in the drawing being at the front of the vehicle 10 and being steerable by a steering mechanism (not shown). The left hand pair of wheels 12 are at the rear of the vehicle and are mounted on respective axles 14a, 14b coupled to a generator 16, such as an alternator or dynamo, adapted to produce an electric current on an output line 1 8 as a result of rotation of the rear wheel axles 14a, 14b, ie of motion of the vehicle.
In this embodiment the front wheels 12 can be selectively driven by means of respective electric motors 20a, 20b. In other embodiments, any other wheel or wheel combination can have respective electric drive motors 20.
Preferably, and particularly in the case where they are to drive the front wheels, the motors 20 are integrated directly into the wheels 12 so that they do not interfere with the steering mechanism. Such motors are known in the art as "wheel motors". Each motor wheel assembly can comprise an electric motor, a motor-wheel slave controller (MWSC) including power and control electronics, a brake, wheel bearings, a steerable front suspension interface and a heat sink.
The motors can, for example be DC, AC and 3-phase AC induction types. In the latter case the 3-phase synchronous motor can comprise a central stator supporting the windings and the inverter, surrounded by an external motor wheel which supports permanent magnets. The vehicle wheel is mounted on the motor for direct transmission of torque and to permit free-wheeling.
Control of the motor is achieved by a control system based on a Central Processing Unit (CPU) 24 coupled to each of the motors 20 and to the generator 16.
Energy for driving the motor 20 comes from one or more rechargeable batteries 22, which are also coupled to the CPU 24. In this embodiment, there are Iwo batteries or banks of batteries, 22a, 22b, one of which is used for driving the motors 20 at a given time while the other is being charged at that time by means of the current derived by the generator 16 on the output line 18. The CPU 24 decides at any given time which of the batteries is to be driving the motors 20 and which is to be charged by the generator 16.
The control system, which includes the CPU 24, lies at the heart of the vehicle drive system of the electric vehicle and is responsible for governing the operation of the vehicle. The control system receives inputs from the driver, feedback signals from the motor controllers and motors, and also feedback signals from other operating systems within the vehicle. By way of example only, the feedback signals to the CPU can include signals corresponding to the rotor speed and winding temperatures of the drive motors 20, the output voltage, output current and temperature of each battery 22, the voltage, temperature, current and current direction in the motor controllers, the accelerator pedal position, and whether the vehicle is set for forward or reverse motion.
The basic operation is that during the time that the vehicle is in motion as a result of the motors 20 being driven by one of the batteries (or battery sets) 22, including free-wheeling conditions and when the vehicle is travelling downhill, the other battery is being charged via the generator 16 driven, in this case, by the rotation of the rear axes 14 which rotate with the rear wheels 12. By suitable choice of motor(s) 20, generator(s) 16 and CPU control, the battery being charged can be brought up to and maintained in a fully charged or substantially fully charged state, ready to take over from the other battery when this has been discharged to a predetermined level.
Many different types of battery are in use currently for electric vehicles, the most common being flooded lead acid, sealed gel lead-acid, Nickel Cadmium (Ni Cad) and Nickel Metal Hydride (NiMH).
Whereas they are more expensive, NiMH batteries yield substantially double the performance (energy density per weight of the battery) compared to lead acid batteries. The recharge time is also important. Lead acid batteries can take up to 8 hours to recharge. On the other hand NiCad and NiMH batteries can be recharged much more quickly, for example from a 20% state of charge to an 80% state of charge in less than 25 minutes. However, by pulsing the recharging current in accordaiice with techniques now available, batteries can now be recharged in perhaps 10-15 minutes.
Pulsed charging would probably be used in the present technique, along with NiCad or NiMH batteries in order to achieve fast charging of the discharged battery 22 after changeover has been selected by the CPU.
It is envisaged that by suitable selection of the motor(s), generator(s) and CPU control it will be possible for sufficient charging to take place during running to keep the battery key charged at a substantially fully charged state, although some re- charging from an external source may sometimes be necessary. This can be achieved, for example, using a conventional battery charger coupled directly to the mains current supply. Another technique uses inductive coupling where a "paddle" coupled to a power supply fits into a socket on the vehicle. Instead of transferring power by a direct wire connection, power is transferred by induction using a magnetic coupling between the windings of two separate coils, one in the paddle and one disposed in the vehicle itself.
In addition to the regenerative charging obtained by the generator directly from the kinetic energy of the vehicle when being driven by the motors 20, energy can be extracted from the drive motors 20 for charging the selected battery during braking of the vehicle, ie using conventional regenerative braking techniques.
Other energy generating devices, such as rotating vanes (windmills) attached to the vehicle can provide additional energy during forward motion of the vehicle for assisting recharging of the selected battery.
