Similarly, a problem mentioned in the background section or associated with the subject matter of the background section should not be assumed to have been previously recognized in the prior art. The subject matter in the background section merely represents different approaches, which in and of themselves may also correspond to implementations of the claimed technology.
The number of electric vehicles (EVs) in operation has grown exponentially in recent years. Conventionally, EVs have relied on electrochemical batteries, e.g., lithium-ion and lead-acid batteries. However, electrochemical batteries suffer from a variety of disadvantages including a short shelf-life, low peak power, and a limited number of charging/discharging cycles.
More recently, supercapacitors have begun to replace lead-acid and lithium-based batteries in data storage applications requiring high current/short duration backup power. Supercapacitors are also finding use in a variety of high peak power and portable applications in need of high current bursts or momentary battery backup. Compared to batteries, supercapacitors provide higher peak power bursts in smaller form factors and feature longer charge cycle life over a wider operating temperature range.

The system 100 may further include a supercapacitor (SC) adder module 104, which may be embodied as a self-contained unit with various connections 126. Although four connections 126 are illustrated in
As described in greater detail below, the supercapacitor adder module 104 may also include a control system to automatically switch between the electrochemical battery 102 and the supercapacitor batteries 112 (or vice versa) when powering the electric vehicle 120. In one embodiment, the supercapacitor adder module 104 including the supercapacitor batteries 112 has a higher capacity than a traditional electrochemical battery 102 and delivers a greater charge at a smaller weight and size. The supercapacitor batteries 112 may include any type or configuration of supercapacitor batteries or cells having enough capacity to enhance the integration of the supercapacitor adder module 104 and the electrochemical battery 102. The supercapacitor batteries 112 may be configured to have the same voltage as the electrochemical battery 102 so to easily integrate into the electric vehicle 120.
Principles for the design, manufacture, and operation of supercapacitors are described, by way of example, in U.S. Pub. No. 2019/0180949, titled “Supercapacitor,” published Aug. 29, 2017; U.S. Pat. No. 9,318,271, titled “High-Temperature Supercapacitor,” issued Apr. 19, 2016; U.S. Pub. No. 2020/0365336, titled “Energy Storage Device,” published Nov. 19, 2020; U.S. Pat. No. 9,233,860, titled “Supercapacitor and Method for Making the Same,” issued Jan. 12, 2016; and U.S. Pat. No. 9,053,870, titled “Supercapacitor with a Mesoporous Nanographene Electrode,” issued Jun. 9, 2015, all of which are incorporated herein by reference.
The supercapacitor adder module 104 may be small enough to fit into an existing battery compartment of the electric vehicle 120. The electric vehicle 120 may be any type of electric vehicle, non-limiting examples of which may include automobiles, trucks, vans, fork lifts, carts (such as golf carts or baby carts), motorcycles, electric bikes scooters, autonomous vehicles, mobile robotic devices, hoverboards, monowheels, Segways®, wheelchairs, drones, personal aircraft, robotic devices, aquatic devices (such as boats, Jet Skis®, diver propulsion vehicles or underwater scooters), or the like.
The supercapacitor adder module 104 may be configured to easily connect to the electric vehicle 120 using standard battery connections 126 and may utilize circuitry including a first electrical path 122 and a second electrical path 124. The circuit layout of the first electrical path 122 and the second electrical path 124 is one example of how switching could occur, but there could be many others depending upon how the supercapacitor adder module 104 is designed. As illustrated in
There are many reasons to switch between the electrochemical battery 102 and supercapacitor batteries 112 (and vice versa) when powering the electric vehicle 120. For example, switching from the electrochemical battery 102 to the supercapacitor batteries 112 may allow the supercapacitor batteries 112 to run the electric vehicle 120 when higher amperage is desired quickly, such as when the electric vehicle 120 is moving up a steep hill or is predicted to move up the hill based on predefined or predicted route. In other examples, switching may be performed to optimize discharge, as the discharge is typically faster for the supercapacitor batteries 112 than the electrochemical battery 102.
In a further example, switching may be performed to enhance the long-term power storage of the electrochemical battery 102. For example, switching from the electrochemical battery 102 to the supercapacitor batteries 112 may be done to enhance the lifespan of the electrochemical battery 102, as the supercapacitor batteries 112 can be charged millions of times before they start to degrade, whereas the electrochemical battery 102 may only allow 500 to 1,000 charging cycles.
In some embodiments, a driving profile associated with the electric vehicle 120 may specify that supercapacitor batteries 112 are to be preferentially used to reduce charging cycles of the electrochemical battery 102 or otherwise reduce usage thereof extend the useful life of the electrochemical battery 102. The driving profile may be specified by a user in some embodiments via a user interface (not shown) integrated with the electric vehicle 120 and stored in a memory for later retrieval.
In one embodiment, the supercapacitor adder module 104 further includes a switch and test module 106. The switch and test module 106 may include a current tester which performs amperage measurement in the first electrical path 122 to determine how much amperage is drawn through the electrochemical battery 102 and the electric vehicle 120. As explained in greater detail below, the switch and test module 106 may also be instructed to disconnect or connect the electrochemical battery 102 using a digitally controlled, high-powered relay. The switch and test module 106 may operate in milliseconds, such that switching will not disrupt the smooth operation of the electric vehicle 120.
The supercapacitor adder module 104 may also include a supercapacitor controller 108 and a base module 116. As described in greater detail below, the base module 116 may execute a supercapacitor controller module 108 to switch between the electrochemical battery 102 and the supercapacitor batteries 112, allowing the supercapacitor controller 108 to disconnect the first electrical path 122 by instructing the switch and test module 106 to disconnect the first electrical path 122 and to switch the supercapacitor batteries 112 onto the second electrical path 124 using high-powered switching relays. The supercapacitor controller 108 also determines if the base module 116 executes the supercapacitor controller module 108 to switch between the supercapacitor batteries 112 and the electrochemical battery 102, in which case the supercapacitor controller 108 disconnects the second electrical path 124 and then instructs the switch and test module 106 to connect the first electrical path 122 allowing the electrochemical battery 102 onto the first electrical path 122 to power the electric vehicle 120.
The supercapacitor adder module 104 may further include a controller 110, which may be embodied as processor to execute instructions in a memory 114, allowing read/write access to a database 118 and performing instructions to activate or deactivate the switch and test module 106 and the supercapacitor controller 108. The controller 110 also enables current measurements from the first electrical path 122 and/or the second electrical path 124 to be collected and stored (in real-time) in the database 118. The controller 110 also controls the switching of the high-powered switching relay in the first electrical path 122 and the second electrical path 124 during execution of the base module 116.
The memory 114 may store the base module 116 and its sub-modules, as well as the database 118. Further, the base module 116 may read the database 118 and then execute the switch and test module 106. The switch and test module 106 can sense whether the electric vehicle 120 is connected and whether the electrochemical battery 102 is connected. The switch and test module 106 also reads the current (amperage) through the first electrical path 122 when the electric vehicle 120 is in operation. The database 118 allows for reading and writing data from the base module 116 and its sub-modules, as well as data associated with the switch and test module 106 and the supercapacitor controller 108.
The base module 116 controls the switch and test module 106 and measures amperage (current) flowing through both paths 122, 124. The base module 116 calculates an amperage use pattern from the database 118 and determines whether the amperage use pattern requires supercapacitor batteries. If so, the base module 116 controls the supercapacitor controller 108 to switch off the first electrical path 122 and turn on the second electrical path 124 connecting the supercapacitor batteries 112 through the supercapacitor controller 108 to the electric vehicle 120. The base module 116 also determines whether amperage use patterns require switching from supercapacitor battery 112 back to the electrochemical battery 102.
The base module 116 may include various sub-modules, including, without limitation, an energy optimization module 128, a charging module 130, a maintenance module 132, a speed optimization module 134, a control module 136, a health and safety module 138, a security module 140, and a motor control module 142. Each of the sub-modules may be configured with read/write access to the database 118. These modules will be described in greater detail below.
The energy optimization module 128 may optimize the electric charge of the plurality of supercapacitor batteries 112 and the electrochemical battery 102. The energy optimization module 128 may be able to read all data in the database 118. In one embodiment, the energy optimization module 128 may be configured to determine the percentage of electric charge available in each of the plurality of supercapacitor batteries 112 and electrochemical battery 102. The energy optimization module 128 may also be able to collect data related to each of the plurality of supercapacitor batteries 108 and electrochemical battery 102 required for one run time of the electric vehicle 120, as measured by an electric vehicle sensor (not shown). The energy optimization module 128 may rely on the supercapacitor batteries' 112 premeasure performance, such as the charge curve over time and the discharge curve over time at various loads. Once this premeasure performance is defined, it is stored in the database 118. The energy optimization module 128 may also rely on other curves, such as, without limitation, voltage vs. current charge and discharge curves, temperature as a discharge function under various loads, humidity versus storage time at a particular voltage, etc.
In some embodiments, the energy optimization module 128 may evaluate a future load prediction due to a user-defined or predicted route for the electric vehicle 120, where the energy optimization module 128 may determine that some batteries would be sufficient to satisfy the future load prediction, such that the energy optimization module 128 determinations may inform which batteries may be used for the planned trip. The energy optimization module 128, using premeasurements for the supercapacitor batteries 112 and electrochemical battery 102 may determine that, even though some of the batteries would be sufficient for the preplanned trip, some of the batteries are used, leaving the rest of the batteries with usable future charge in case there is a deviation from the planned trip.
The energy optimization module 128 may use preplanned route optimization or route optimization in many ways, including, but not limited to, applying artificial intelligence and/or machine learning (AI/ML) to historical data, i.e., historical data on actual use of a standard route, etc. The energy optimization module 128 may include an ML engine and/or an ML model that can include one or more neural network (NNs), one or more convolutional neural networks (CNNs), one or more trained time delay neural networks (TDNNs), one or more deep networks, one or more autoencoders, one or more deep belief nets (DBNs), one or more recurrent neural networks (RNNs), one or more generative adversarial networks (GANs), one or more conditional generative adversarial networks (cGANs), one or more other types of neural networks, one or more trained support vector machines (SVMs), one or more trained random forests (RFs), one or more computer vision systems, one or more deep learning systems, one or more classifiers, one or more transformers, or combinations thereof.
The energy optimization module 128 may write all data, alerts, and calculations that may have been created to the database 118.
The charging module 130 determines whether charging is needed or not. For example, the charging module 130 may be configured to determine the charging and discharging status of the electrochemical battery 102 and/or the supercapacitor batteries 112 in real-time. The charging module 130 may be configured to charge the electrochemical battery 102 and/or the supercapacitor batteries 112 to meet a desired or predicted charge cycle. For example, in one embodiment, the desired charge cycle of each of the batteries 102, 112 may be two hours when each is charged up to a threshold limit of 90 percent.
The maintenance module 132 maintains the supercapacitor adder module 104 (including the supercapacitor batteries 112) and electrochemical battery 102. In one embodiment, the maintenance module 132 may be configured to run internal diagnostics of the supercapacitor adder module 104 and electrochemical battery 102 by accessing and testing the plurality of supercapacitor batteries 112 and the electrochemical battery 102. The maintenance module 132 may be run at specific periods on an internal clock (not shown) or could run if an alert is received from another module, such as receiving a notification from the charging module 130 that the charging is not working correctly. Further, the maintenance module 132 may determine whether the electric vehicle 120 is consuming electric charge at a higher rate than a desired or predicted rate for a particular run time, suggesting that a maintenance check may be needed.
In one embodiment, the maintenance module 132 may send a maintenance request to the base module 116, indicating that the plurality of supercapacitor batteries 112 and/or the electrochemical battery 102 is not coupled correctly. For example, the electric vehicle 120 may be experiencing more load while driving over the predefined path. Further, the maintenance module 132 may determine the performance of the supercapacitor adder module 104 and electrochemical battery 102 for retrieved performance from the database 118 (base on prestored design data). In another embodiment, the maintenance module 132 may perform an internal maintenance check to determine whether each component of the supercapacitor adder module 104 and electrochemical battery 102 is functioning up to its desired requirement. The maintenance module 132 may write all data, alerts, and calculations that may have been created to the database 118 for access by the base module 116 and other sub-modules.
The speed optimization module 134 may enhance the performance of the supercapacitor adder module and electrochemical battery 102 by minimizing the consumption of electric charge. In one embodiment, the speed optimization module 134 may be configured to determine that the electric vehicle is moving down an incline, such that the supercapacitor adder module 104 and the electrochemical battery 102 are not required to provide charge. In such a case, the speed optimization module 134 may stop the flow of the electric charge while the electric vehicle 120 is moving downward. The acceleration and orientation of the electric vehicle 120 may be measured by sensors (not shown). Further, the speed optimization module 134 may retrieve information related to maintenance of the electric vehicle 120 from the database 118 to measure the amount of electric charge consumed by the electric vehicle 120 before maintenance. The speed optimization module 134 may write all data, alerts, and calculations that may have been created to the database 118 for access by the base module 116 and other sub-modules.
The health and safety module 138 may be configured to provide health and safety-related information pertaining to the supercapacitor batteries 112 (danger of fire or explosion) as can be predicted by thermal sensors on the supercapacitor batteries 112 (not shown). The security module 140 may also evaluate and warn users how external charging hookups may be configured. Both the health and safety module 138 and the security module 140 may write all data, alerts, and calculations that may have been created to the database 118 for access by the base module 116 and other sub-modules.
The motor control module 142 may be configured to evaluate the performance of the supercapacitor adder module 104 and electrochemical battery 102 in at least two modes, e.g., an enhanced torque mode and an economy mode. The enhanced torque mode may be employed when the electric vehicle 120 moves up an incline (measured by amperage in the switch and test module 106 or by other sensors in the electric vehicle 120). For example, the motor of the electric vehicle 120 will consume a greater amount of electric charge (and greater amperage) to generate more torque for moving the electric vehicle upward. The economy mode may be initiated when the electric vehicle 120 moves down an incline. Less electric charge is needed to drive the electric vehicle downward or when the electric vehicle 120 is extending beyond the run time. In one embodiment, the motor control module 142 may be configured to monitor and anticipate the performance of the motor of the electric vehicle 120 according to the enhanced torque mode or the economy mode. Further, the motor control module 142 may retrieve data related to parameters affecting the movement of the electric vehicle 120 in the database 118 and write all data, alerts, calculations that may have been created to the database 118.
The process begins with the base module 116 reading all data from the database 118 at step 200. The base module 116 then reads the switch and test module 106 at step 202 to determine if an electric vehicle 120 is connected and if the electrochemical battery 102 is connected. At step 204, the switch and test module 106, under control of the base module 116, measures the amperage passing through the first electrical path 122 (either inline or via a digital clamp meter) between the electrochemical battery 102 and the electric vehicle 120, as well as the amperage passing through the second electrical path 124 between the supercapacitor batteries 112 and the electric vehicle 120 when the electric vehicle 120 is running.
At step 206, the switch and test module 106 stores amperage data and associated time stamps in the database 118. The base module 116 then calculates, at step 208, an amperage use pattern from the database 118. The amperage use pattern for the electrochemical battery 102 may be the average amps used in one hour. In some embodiments, the amperage use pattern of the electrochemical battery 102 could be the amperage data over time and compared to a threshold or the amperage use pattern of an ideal or historical electrochemical battery previously stored in the database 118. For example, the base module 116 may determine whether the amperage meets or exceeds a predefined, dynamic, and/or user-defined threshold value—or drops below a threshold value—which may be used as a condition to determine whether to switch between the electrochemical battery 102 and supercapacitor batteries 112 (or vice versa).
The prestored historical amperage use pattern may provide metadata that can be read to instruct the base module 116 to switch between the electrochemical battery 102 and supercapacitor batteries 112. In some embodiments, a switching threshold and its metadata may be prestored in the database 118. If the amperage is used, for example, at or above the switching threshold, the metadata would instruct the base module to switch from the electrochemical battery 102 to the supercapacitor batteries 112.
At step 210, the base module 116 determines if the amperage use pattern requires supercapacitor batteries 112. If so, the base module 116 instructs the supercapacitor controller 108 to switch off the first electrical path 122 and turn on the second electrical path 124 connecting the supercapacitor batteries 112 through supercapacitor controller 108 to the electric vehicle 120. The base module 116 determines if amperage use patterns require an action to switch from electrochemical battery 102 to supercapacitor batteries 112 either by reading metadata from step 208 or by determining if amperage use data is beyond a preset threshold. It should be noted that the system 100 may be more intelligent by setting a threshold on amperage of supercapacitor batteries 112 to switch back to the electrochemical battery 102 if needed. It should be noted there may also be hybrid switching by switching on both supercapacitor batteries 112 and electrochemical battery 102.
At step 212, The base module 116 determines if the amperage use pattern does not require supercapacitor batteries 112. If the amperage use pattern does not require supercapacitor batteries 112, the base module 116 instructs the supercapacitor controller 108 to switch on the first electrical path 122 and turn off the second electrical path 124 that connects the supercapacitor batteries 112 through supercapacitor controller 108 to electric vehicle 120. The base module 116 then stores all data in database 118 at step 214.
In one embodiment, the base module 116 then executes the energy optimization module 128 at step 216. The base module 116 then executes charging module 130 at step 218. The base module 116 then executes maintenance module 132 at step 220. The base module 116 then executes the speed optimization module 134 at step 222. The base module 116 then executes the control module 136 at step 224. The base module 116 then executes the health and safety module 138 at step 226. The base module 116 then executes the security module 140 at step 228. The base module 116 then executes the motor control module 142 at step 230. At step 232, the base module 116 then loops to step 202.
The process begins with the supercapacitor controller 108 polling the base module 116 at step 300. At step 302, if the supercapacitor controller 108 determines that the base module 116 executes the supercapacitor controller module 108 to switch between the electrochemical battery 102 and the supercapacitor batteries 112, then the supercapacitor controller 108 disconnects the first electrical path 122 by instructing the switch and test module 106 to disconnect the first electrical path 122 via the high-powered switching relay and the supercapacitor controller 108 switches the supercapacitor batteries 112 onto the second electrical path 124 using the high-powered switching relays so that the electric vehicle 120 is powered by the supercapacitor batteries 112.
At step 304, if the supercapacitor controller 108 determines that the base module 116 executes the supercapacitor controller module 108 to switch between the supercapacitor batteries 112 and the electrochemical battery 102, then supercapacitor controller 108 disconnects the second electrical path 124 using high-powered switching relays and then instructs the switch and test module 106 to connect the first electrical path 122 via the high-powered switching relay. This allows the electrochemical battery 102 onto the first electrical path 122 so that electric vehicle 120 is powered by the electrochemical battery 102.
