Definitions
- the present invention relates to power management for an electric drive system and, in particular, to a power system for an electric vehicle.
- Electric vehicles use rechargeable batteries which power electric motors for propulsion.
- the practical issue is that, currently, most commercially viable rechargeable batteries can only store a limited amount of sufficient energy for powering the motor before requiring a recharge.
- a number of modern commercially available electric vehicles are able to offer approximately 150-200km range on a fully charged battery.
- the recharging time can be 6-8 hours to fully recharge the battery.
- An object of the present invention is to provide a power system for an electric vehicle which will overcome or substantially ameliorate at least some of the deficiencies of the prior art, or will at least provide an alternative.
- a power system for an electric vehicle comprising:
- an electric generator arranged to convert mechanical energy, due to movement of the vehicle, into electrical energy
- a first and a second rechargeable electrical power storage device wherein said first and second rechargeable electrical power storage devices are electrically isolated from one another;
- a controller arranged to selectively connect one of the first and second rechargeable electrical power storage device with the electric motor in order to power the motor, and selectively connect the other of the first and second electrical power storage device with the generator to receive charging.
- the controller connects the first rechargeable electrical power storage device with the electric motor to power the motor, wherein, when the charge level of the first rechargeable electrical power storage device is at or below a predetermined charge level, the controller disconnects the first rechargeable electrical power storage device from the motor, connects the first rechargeable electrical power storage device with the generator to receive charge and connects the second rechargeable electrical power storage device with the electric motor to power the motor; wherein, when the charge level of the second rechargeable electrical power storage device is at or below the predetermined charge level, the controller disconnects the second rechargeable electrical power storage device from the motor, disconnects the first rechargeable electrical power storage device from the generator, connects the second rechargeable electrical power storage device with the generator to receive charge and connects the first rechargeable electrical power storage device with the electric motor to power the motor; wherein the controller continues to repeat the process of selectively connecting and disconnecting the first and second rechargeable electrical power storage devices between the motor and generator until the charge levels in both the first and second rechargeable electrical power storage devices are at or below the predetermined charge
- the controller is prevented from connecting a rechargeable electrical power storage device to the generator when the charge level in the rechargeable electrical power storage device is at maximum capacity.
- the controller can connect the generator to an alternative electrical load, such as a climate control system for the vehicle.
- the system further comprises a third rechargeable electrical power storage device electrically isolated from said first and second rechargeable electrical power storage devices, wherein said third rechargeable electrical power storage device is a high discharge device; wherein said controller selectively connects said third rechargeable electrical power storage device to the motor when load requirements exceed the capabilities of the first and second rechargeable electrical power storage devices.
- the controller may selectively connect the third rechargeable electrical power storage device to the generator to receive charging when one of the first and second rechargeable electrical power storage device is connected to the motor and the other of the first and second rechargeable electrical power storage device is at maximum capacity charge level.
- the electric motor is an in-wheel motor arranged with a first wheel of the vehicle and the electric generator is an in-wheel motor-generator arranged with a second wheel of the vehicle.
- the first wheel may have a larger diameter than the second wheel.
- a second in-wheel motor-generator may be arranged with a third wheel of the vehicle.
- the system includes an additional generator for generating additional charging energy, such as a solar system.
- a controller for controlling the power system for an electric vehicle and a method of controlling the power system for an electric vehicle.
- Fig. 1 is a block diagram of a power system in accordance with a preferred embodiment of the present invention
- Fig. 2 illustrates a controller and connections in accordance with another preferred embodiment of the present invention
- Fig. 3 illustrates a logic diagram for use by the controller
- Fig. 4 shows an electric vehicle in accordance with a preferred embodiment of the present invention.
- the disclosure relates to a power system for an electric vehicle, see Figs 1 and 2.
- the electric vehicle illustrated is a three-wheel vehicle, see Fig. 4.
- the rear wheel 25 of the vehicle has an imbedded in-wheel motor 20, which in the present embodiment represents a dedicated drive motor for the vehicle. In other words, it is this drive motor 20 which is used to provide the mechanical energy to propel the vehicle.
- Each of the front wheels 85 also has an imbedded in-wheel motor 80.
- these motors 80 are configured to act as dedicated generators. In other words, these generators 80 convert the rotation of the respective wheel into electrical energy. Potentially, only one of the front wheels 85 could have an imbedded motor.
- the power system also includes two deep cycle rechargeable electrical power storage devices 50, 60 which are isolated from one another. As will be described, these devices 50, 60 are electrical power sources predominantly employed to power the drive motor 20 under normal driving conditions, i.e. when current load requirements are below a certain threshold, such as less than 40A. Each device 50, 60 is a battery pack of series connected Lithium-Ion batteries which offer 48V, 56AH. It will be appreciated that each device 50, 60 could be a single large Lithium-Ion battery or conceivably be a suitable supercapacitor.
- the power system further includes a high discharge rechargeable electrical power storage device 40, which is also isolated from the other devices 50, 60.
- this device 40 is an electrical power source employed for when current load requirements are above the optimum threshold for the deep cycle devices 50, 60, such as greater than 40A. In practice, the drive motor 20 will require these excessive currents for short periods during vehicle take-off.
- the drive motor 20 receives input electrical power from only one of the devices 40, 50, 60 at any one time.
- the selection of which device powers the motor 20 at any given time is selected by a controller 10. It will be appreciated that the DC output of the selected device requires conversion into a 3-phase AC current for input into the motor 20 which is done by a suitable inverter 100.
- the resultant rotation of the front wheels 85 causes the generators 80 to generate electricity. In practice, useful generation begins when the vehicle reaches speeds of approximately 10km/h and above. Relevant to the present invention, the generated electricity can be used to recharge any electrical power storage device 40, 50, 60 which is not connected to the motor 20. It will be appreciated that, in order to do so, the 3-phase AC current generated output from the generators 80 needs to be converted into DC current, which is done by a suitable rectifier 90.
- a controller 10 operates switches, ideally in the form of contactors, under instruction from a processor which monitors various system parameters and determines suitable connections between system components in accordance with the parameters.
- the main parameters under consideration are the current load requirements requiring electrical power, and the current charge levels of the various power storage devices 40, 50, 60.
- the electrical power to the drive motor 20 is provided by a first one of the deep cycle rechargeable electrical power storage devices 50 while the second other deep cycle rechargeable electrical power storage device 60 can be recharged by output from the generators 80.
- the controller 10 causes a switching between the devices so that the second device 60 powers the motor 20 while the first device 50 is recharged by the generators 80.
- the controller 10 switches between the devices again. The switching between devices continues until the charge level in both devices 50, 60 is at the predetermined level.
- the predetermined level is set at 70% of full charge capacity. It is understood that this represents an optimum level of depletion for Lithium-Ion batteries before recharging, which will prolong the life cycle of the batteries. Using 70% discharge in Lithium Ion deep cycle batteries in currently commercially available batteries achieves 8000 cycles rather then 1600 cycles only at full discharge. It will be appreciated that a different predetermined level can be selected and, in fact, may be suitable for different types of power storage devices. In fact, the controller can be provided with a user input interface 110 which would allow a user to select and set the predetermined level.
- both devices 50, 60 are depleted to the 70% charge level, the devices 50, 60 require recharging from an external electrical power source, for example a charging station.
- an external electrical power source for example a charging station.
- in-wheel generators 80 did have a negative impact upon the top speed of the vehicle.
- the in-wheel motor employed normally provides a top speed of around 45km/h; however, with the generators 80 in the front wheels 85 the vehicle's top speed was found to be reduced to around 42km/h. Nevertheless, the driving range was found to be increased by almost four times. Consequently, the trade-off between increased range and reduced speed appears acceptable.
- FIG. 3 An example of a logic diagram for the controller's switching is shown in Fig. 3. As shown, when the controller 10 determines that the current load requirements for the motor 20 exceed a selected threshold, the high discharge power storage device 40 is employed to power the motor 20. When the current load requirements fall back down to this threshold, the controller 10 switches to one of the deep cycle power storage devices 50, 60 for powering the motor 20.
- the logic flow dictates how the controller 10 causes the generator 80 output to be directed.
- the controller 10 normally directs generated power for recharging the deep cycle device 50, 60 having the lowest charge level. In the case that the charge levels are the same, the controller 10 is biased towards recharging one of the devices 50, 60 before the other. In the case that both devices 50, 60 are actually fully charged (which occurs, for example, when the vehicle initially operates after an external recharge), the generated power can be directed to an alternative electrical load 70.
- this alternative electrical load could be a climate control system 70 for the vehicle, e.g. an air conditioner or heater.
- the controller 10 switches to one of the deep cycle devices 50, 60 for powering the motor 20 until the charge level of the loaded device falls to 70%, whereupon the loaded device is switched to recharging and the other device is switched to load. As shown, the controller 10 normally directs generated power to the unloaded deep cycle device. However, if the unloaded deep cycle device is actually fully charged, then the controller can switch the high discharge device 40 to receive the charge. If both the unloaded deep cycle device and the high discharge device are fully charged, then the generated power can be directed to the alternative electrical load 70.
- a capacitor 30 should be connected with the motor 20 to maintain power to the motor 20 during switching transition.
- the power system can be enhanced by providing an additional generating source, such as a solar system 150 or wind turbine, thereby increasing the potential recharging capabilities.
- an additional generating source such as a solar system 150 or wind turbine
- controller can cause a switching of the three phase inputs to the motor 20 in order to cause the motor to operate in reverse and, hence, reverse the driving direction of the electric vehicle.
- controller 10 could switch the motor 20 into a generator during periods in which the vehicle is moving but no driving power is required, for example during braking, slowing down without braking, or driving downhill or coasting. It will be appreciated that the controller 10 would need to switch the generating output of the motor 20 via a suitable rectifier to convert to DC.
- the controller 10 could facilitate the switching of the in-wheel generators 80 into additional driving motors to provide an all-wheel drive option for the vehicle in case of emergency power requirements or hazardous surfaces. Obviously, it would be undesirable to maintain this option for prolonged periods as it removes the recharging capability and would deplete the batteries quickly.
- controller can be provided with suitable dip switches 120 and communication ports 130, for example RJ45 connections, to link multiple controllers together to control expanded systems.
- the processes and logic flows described in this specification can be performed by one or more programmable processors executing one or more computer programs to perform functions by operating on input data and generating output, thereby tying the process to a particular machine (e.g., a machine programmed to perform the processes described herein).
- the processes and logic flows can also be performed by, and apparatus can also be implemented as, special purpose logic circuitry, e.g., an FPGA (field programmable gate array) or an ASIC (application specific integrated circuit).
- Computer readable media suitable for storing computer program instructions and data include all forms of non-volatile memory, media and memory devices.
- the processor and the memory can be supplemented by, or incorporated in, special purpose logic circuitry.
- this disclosure makes reference to electric vehicles, which include but are not limited to, cars, trucks, vans, motorcycles, tractor trailers, tractors of all sizes, construction vehicles, mining vehicles, maintenance vehicles, trains, buses, boats, airplanes, golf carts, wheel chairs, mobility carts and scooters, and power chairs, this disclosure is not intended to be limited to electric vehicles.
- processor may refer to any device or portion of a device that processes electronic data, e.g., from registers and/or memory to transform that electronic data into other electronic data that, e.g., may be stored in registers and/or memory.
- a "computer” or a “computing device” or a “computing machine” or a “computing platform” may include one or more processors.
- the methodologies described herein are, in one embodiment, performable by one or more processors that accept computer-readable (also called machine-readable) code containing a set of instructions that when executed by one or more of the processors carry out at least one of the methods described herein.
- Any processor capable of executing a set of instructions (sequential or otherwise) that specify actions to be taken are included.
- a typical processing system that includes one or more processors.
- the processing system further may include a memory subsystem including main RAM and/or a static RAM, and/or ROM.
- a computer-readable carrier medium may form, or be included in a computer program product.
- a computer program product can be stored on a computer usable carrier medium, the computer program product comprising a computer readable program means for causing a processor to perform a method as described herein.
- connection when used in the claims, should not be interpreted as being limited to direct connections only. Thus, the scope of the expression a device A connected to a device B should not be limited to devices or systems wherein an output of device A is directly connected to an input of device B. It means that there exists a path between an output of A and an input of B which may be a path including other devices or means. "Connected” may mean that two or more elements are either in direct physical or electrical contact, or that two or more elements are not in direct contact with each other but yet still co-operate or interact with each other.
