Description

Method for Electrifying Gasoline Motorcycles and Battery Power Pack Devices

[0001] The embodiments disclosed in this document relate to a method for electrifying a gasoline motorcycle and a battery power pack device that can be used in an eco-friendly driving platform environment for an electric converted motorcycle.

[0002] Recently, due to the increasing demand for electric vehicles, the demand for batteries is also rising. A battery is an energy storage device that converts energy generated by chemical reactions into electrical energy for use, and this category includes primary cells, secondary cells, and fuel batteries. Generally, a battery that cannot be reused because it fails to react when electrical energy is applied again after a single reaction is called a primary battery, while a battery that can be used continuously through reversible reactions that occur repeatedly is called a secondary battery.

[0003] Electric vehicles primarily utilize rechargeable secondary batteries. Four-wheeled vehicles equipped with rechargeable secondary batteries are rapidly becoming popularized in line with the global trend toward carbon neutrality. Along with this, platforms for charging and driving four-wheeled vehicles, including related charging stations, are widely available. However, platforms for charging and driving two-wheeled (or three-wheeled) motorcycles are woefully inadequate compared to four-wheeled vehicles. For example, since two-wheeled motorcycles possess fast maneuverability suitable for short-distance travel such as delivery, motorcycle manufacturers are more actively developing and selling internal combustion engine-based two-wheeled motorcycles with the intention that riders replenish other fuels (e.g., gasoline) quickly instead of spending long hours charging the battery. Consequently, riders of internal combustion engine-based two-wheeled motorcycles may simply maintain their existing motorcycles and be reluctant to invest in purchasing new electric motorcycles.

[0004] For the reasons mentioned above, the electrification of internal combustion engine-based two-wheeled motorcycles was bound to be slow.

[0005] In the various embodiments disclosed in this document, an eco-friendly driving platform for an electric converted motorcycle can be provided to replace an internal combustion engine-based motorcycle with an electric-based motorcycle equipped with a rechargeable secondary battery.

[0006] In particular, the present invention aims to provide a method for electrifying a gasoline motorcycle and a battery power pack device that can be used in an eco-friendly driving platform environment for electric converted motorcycles.

[0007] According to one embodiment, an eco-friendly driving platform for an electric modified motorcycle comprises: an electric modified motorcycle equipped with a first battery capable of recharging in a slot; a battery station that provides a second battery replaceable in the slot based on the reference capacity and remaining capacity of the first battery; and an eco-friendly management server that receives identification information corresponding to the electric modified motorcycle from the battery station based on the provision of the second battery from the battery station to the electric modified motorcycle, wherein the eco-friendly management server can share history information, including the driving history of the electric modified motorcycle from the time when the electric modified motorcycle is structurally changed from an internal combustion engine-based structure to an electrification-based structure until the time when the second battery is provided replaceable in the slot, with a user terminal corresponding to the identification information, based on storing and managing the identification information in the form of a blockchain-based NTF (Non-Fungible Token, NFT).

[0008] According to one embodiment, the electric modified motorcycle stores driving information—the driving information includes driving purpose, driving pattern, operating environment, and battery status—and status information by mapping them together, and based on the driving information and status information, predicts the remaining effective life of the first battery relative to the life according to the reference capacity, and based on the remaining capacity and the remaining effective life, transmits a battery replacement request to the battery station to replace the first battery with the second battery.

[0039] Therefore, the embodiments described in this specification and the configurations illustrated in the drawings are merely the most preferred embodiments of the present invention and do not represent all of the technical ideas of the present invention; thus, it should be understood that various equivalents and modifications that can replace them may exist at the time of filing this application.

[0040] FIG. 1 is a block diagram illustrating an eco-friendly driving platform for an electric modified motorcycle according to one embodiment.

[0041] Referring to FIG. 1, the eco-friendly driving platform of an electric modified motorcycle may include an electric modified motorcycle (110), a battery station (120), an eco-friendly management server (130), and a user terminal (140). The above-described configurations are configured so that multiple nodes can communicate with each other through a blockchain network (101).

[0042] According to one embodiment, the electric modified motorcycle (110) may include a two-wheeled (or three-wheeled) motorcycle that has been modified from an existing internal combustion engine-based motorcycle into a battery-based electric motorcycle capable of operation. Here, modification may mean a structural change in which an electric drive motor is installed, including a battery slot, after separating the existing internal combustion engine structure from the motorcycle, so as to be able to mount a battery. Such an electric modified motorcycle (110) may include a power management module (111), a first battery (112), and a processor (113).

[0043] According to one embodiment, the power management module (111) can manage the power supplied to the electric modified motorcycle (110). In one embodiment, the power management module (111) can charge the first battery (112) using power supplied from an external source. In one embodiment, the power management module (111) can control the charging and discharging of the battery (112). In one embodiment, the power management module (111) can supply power supplied from the battery (112) or an external source to the internal circuit of the electric modified motorcycle (110). In one embodiment, the power management module (110) may correspond to at least one of a power management integrated circuit (PMIC) and a charging circuit.

[0044] According to one embodiment, the first battery (112) can supply power or power, energy to at least one component of the electric modified motorcycle (110). In one embodiment, the first battery (112) can be charged by power supplied from the power management module (110). Alternatively, the first battery (112) mounted in the slot of the electric modified motorcycle (110) may be a battery that can be replaced with a second battery (121) at the battery station (120). Here, both the first battery (112) and the second battery (121) may be rechargeable secondary batteries. In one embodiment, the first battery (112) may be discharged by the current consumed by the electric modified motorcycle (110) (e.g., current for driving the electric drive motor).

[0045] According to one embodiment, the first battery (112) may have an L-shape or shape corresponding to the seat portion of the electric modified motorcycle (110). For example, an L-shaped battery pack may be mounted on the seat portion of the electric modified motorcycle (110). A slot for attaching or detaching the battery may be formed in the battery pack. Various square shapes or U-shaped shapes can be created from the L-shape or shape. That is, by appropriately combining L-shaped basic units, the first battery includes a shape corresponding to a slot provided within the electric modified motorcycle, and has a shape that can be mounted and seated within a specific slot of the electric modified motorcycle.

[0046] In one embodiment, the details regarding the structure, electrical characteristics, and design of the first battery (112) may also apply equally to the second battery (121).

[0047] According to one embodiment, the processor (113) can adjust the power supplied to the first battery (112) through the power management module (111). In one embodiment, the processor (113) can set multiple charging intervals up to the battery capacity in a fully-charged state to charge the first battery (112). Additionally, the processor (113) can set different charging currents for each of the set charging intervals. For example, the processor (113) can adjust the target voltage and target current for each first interval that limits the current (e.g., a constant current (CC) interval) and the second interval that proposes the voltage (e.g., a constant voltage (CV) interval).

[0048] According to one embodiment, the processor (113) can perform data mapping by considering the driving environment of the electric modified motorcycle (110). Here, the mapping method may be an optimal data mapping method that considers the driving environment of the electric modified motorcycle (110), which is available in a cloud BMS (battery management system, BMS) or edge processing of a server-based solution. Even if the mapping method used in the present disclosure is performed in a local BMS, subsequent steps such as artificial intelligence learning may be used in a cloud BMS or edge processing of a server-based solution or edge computing.

[0049] First, a step is taken to select a health indicator related to the degradation of a battery (e.g., a first battery (112)) mounted in a slot of an electric modified motorcycle (110). The initial health indicator is based on ohmic resistance information. Alternatively, SOL, which is one of the battery condition indicators, is an indicator that can provide remaining useful life (RUL) information and is selected as an essential performance evaluation indicator for a BMS mounted on an electric modified motorcycle (110) in which an irregular discharge load is applied to the battery, which is the main power source.

[0050] According to one embodiment, the processor (113) may map and store together driving information, including driving purpose, driving pattern, operating environment, and battery status, along with such health indicators, and status information. It is necessary to collect and analyze battery big data considering various operating and driving characteristics of the electric modified motorcycle (110). To this end, since characteristic information such as battery voltage and current varies depending on the driving purpose, driving pattern, operating environment, and battery status, etc., as targets for data mapping, data can be mapped including this information. That is, since the internal state and degradation state of the battery vary according to the user's driving pattern, full-cycle history management is required, and such information can be included. It may be possible to map not only data obtained through the sensors of the electric modified motorcycle (110), but also information extracted from the local BMS and OBD II (on board diagnostics-II).

[0051] Such driving information and status information may include the current magnitude (C-rate) applied to the first battery, load condition, and State of Charge (SOC).

[0052] Additionally, as driving information and status information, the battery status obtained through the sensor of the electric modified motorcycle (110) may include battery SOC, battery voltage, battery current, battery temperature, and battery maximum capacity. For the driving use, information from any one of the driving use list including personal motorcycles and rental motorcycles may be selected. For the driving pattern, information from any one of the driving pattern list including commuting, city driving, delivery, and quick service may be selected. For the operating environment, any one of the climate information list including Siberian cryogenics, temperate climate, African cryogenics, and humid tropical rainforest may be selected.

[0053] In addition, when collecting status information of the electric modified motorcycle (110), the position of the gear, wheel angle (e.g., different wheel angle during sharp turns), brake pedal pressure (e.g., brake pedal pressure due to sudden deceleration), odometer, and wheel rotation speed may also be included.

[0054] The aforementioned health indicators, driving information, and status information can be processed through preprocessing such as noise removal.

[0055] According to one embodiment, the processor (113) performs machine learning, etc., by mapping not only the health indicator but also driving information and state information together, and predicts the health indicator based on the predicted mapping information from the estimation and prediction model, that is, predicts the remaining effective life relative to the lifespan according to the reference capacity (e.g., capacity designed at the time of battery manufacturing) of the battery (e.g., first battery (112)) mounted on the electric modified motorcycle (110) currently in operation. For example, after the processor (113) inputs the mapped health indicator, driving information, and state information into an input layer for learning artificial intelligence, it can predict the remaining effective life of the battery of the electric modified motorcycle (110) currently in operation based on at least some of the health indicator, driving information, and state information of the battery of the electric modified motorcycle (110) currently in operation.

[0056] According to one embodiment, the processor (113) can transmit a battery replacement request to the battery station (120) to replace the first battery (112) with the second battery (121) based on the remaining capacity of the first battery (112) and the predicted remaining effective life of the battery.

[0057] According to one embodiment, the battery station (120) may be provided with a plurality of second batteries (121) for replacing a first battery (112) mounted in a slot of an electric modified motorcycle (110). When the battery station (120) receives a battery replacement request from the electric modified motorcycle (110), it may provide for replacing the first battery (112) in the slot of the electric modified motorcycle (110) with at least one of the plurality of second batteries (121), based on the remaining capacity and remaining effective life of the first battery (112). When the battery station (120) receives a battery replacement request from the electric modified motorcycle (110), it may record the remaining effective life of the first battery (121) to correspond to identification information corresponding to the electric modified motorcycle (110) and transmit it to an eco-friendly management server.

[0058] According to one embodiment, the battery station (120) may be equipped with a battery rack having a specified number (e.g., 10) of battery charging slots. Here, the battery rack may include modular components (e.g., modular racks) that allow the operator of the battery station (120) to conveniently install or expand the capacity of the battery exchange station (120). The battery station (120) may be electrically connected to at least one power source (e.g., power grid, power lines, power storage, power station / substation, etc.) to receive power to charge the second batteries (121) mounted on the battery rack and to perform other operations (e.g., communicating with the eco-friendly management server (130)). The battery station (120) may have a locking mechanism for securing the second batteries (121) mounted on the battery rack.

[0059] According to one embodiment, the memory (122) of the battery station (120) may store commands for determining a battery management plan or command set (e.g., charging rules for each of the second batteries (121)) for a plurality of second batteries (121).

[0060] According to one embodiment, a communication module (123) of a battery station (120) may support the establishment of a direct (e.g., wired) communication channel or a wireless communication channel between an electric modified motorcycle (110), an eco-friendly management server (130), and a user terminal (140), and the performance of communication through the established communication channel. The communication module (123) may include a wireless communication module (e.g., a cellular communication module or a short-range wireless communication module) or a wired communication module (e.g., a LAN (local area network, LAN) communication module or a power line communication module). The communication module (123) may be configured so that a plurality of nodes can communicate with each other through a blockchain network (101).

[0061] According to one embodiment, the eco-friendly management server (130) can receive identification information corresponding to the electric modified motorcycle (110) from the battery station (120) (or electric modified motorcycle (110)) based on the second battery (121) being provided from the battery station (120) to the electric modified motorcycle (110).

[0062] According to one embodiment, the eco-friendly management server (130) stores and manages identification information corresponding to the electric modified motorcycle (110) in the form of a blockchain-based NTF (Non-Fungible Token, NFT), and can share history information including the driving history of the electric modified motorcycle (110) from the time the electric modified motorcycle (110) is structurally changed from an internal combustion engine-based structure to an electrification-based structure until the time the second battery (121) is provided to be replaceable within the slot with a user terminal (140) corresponding to the identification information. The user terminal (140) can check the shared history information through an application for managing the modification history, driving history, and battery replacement history of the electric modified motorcycle (110) owned (or rented) by the user.

[0063] The above NFT can be shared through multiple nodes based on a blockchain network (101) from the time when the internal combustion engine-based electric modified motorcycle (110) is structurally modified into an electric-based structure. In addition, the above NFT can be shared through multiple nodes based on a blockchain network (101) at each time when the driving record of the electric modified motorcycle (110) is verified (e.g., when battery-related data is obtained through the sensor of the modified motorcycle (110)) and when a second battery (121) is provided from the battery station (120) to the electric modified motorcycle (110).

[0064] The above NFT may be a token issued to include a certificate that can verify the authenticity of each, such as the time of modification of the electric modified motorcycle (110), the time when the driving record is confirmed, and the time when the battery is replaced. An NFT, which stands for Non-Fungible Token, is a unit of data stored on a blockchain and refers to a unique and non-exchangeable token. An NFT is issued by storing ownership of digital assets such as photos, videos, and audio on a blockchain, and unlike fungible tokens (FTs) such as cryptocurrencies, it has unique characteristics and value, so it has the characteristic that it cannot be exchanged or replaced one-to-one with other tokens, making it possible to prove copyright and ownership of digital assets.

[0065] According to one embodiment, when the eco-friendly management server (130) receives data from the battery station (120) in which the remaining effective life of the first battery (112) corresponding to the identification information of the electric modified motorcycle (110) is recorded, it can check whether the remaining effective life of the first battery (112) is less than or equal to the specified life. If the remaining effective life of the first battery (112) is less than or equal to the specified life, the eco-friendly management server (130) can generate point payment information to pay environmental points related to carbon reduction to a user terminal (140) corresponding to the identification information of the electric modified motorcycle (110).

[0066] The above point payment information may be managed based on a blockchain. The blockchain manages a distributed ledger containing blocks of identification information, information on the remaining effective lifespan of the first battery (112), and data regarding the point payment information, and may include a plurality of notes, each containing at least one computing device. Additionally, the blockchain may provide functions for recording, updating, and managing driving and battery-related data of various electric modified motorcycles (110) managed by the eco-friendly management server (130) in the distributed ledger. For example, the blockchain may provide functions for recording, updating, and managing data shared between the electric modified motorcycle (110) and the battery station (120), data related to the authentication / authorization of the user terminal (140), etc. Additionally, the blockchain may include functions for access control and encryption of sensitive information such as the user's personal information, verification of the validity of user data, and providing confidentiality and integrity of user data.

[0067] According to one embodiment, the user terminal (140) may be a mobile terminal portable by a user who owns (or rents) an electric modified motorcycle (110). The user terminal (140) may receive environmental points related to carbon reduction from an eco-friendly management server (130) via a blockchain network (101).

[0068] According to one embodiment, the user terminal (140) can receive various functions such as user information, carbon trading information, token authentication information, charging station information, repair shop information, bulletin board management, permission management, and security management from a cloud-based external server. The various functions may be selectively supported depending on the use of the user terminal (140) (e.g., for administrators, for technical support personnel, or for general users).

[0069] Among the functions supported by the aforementioned external server, there may be a function to provide an operational management homepage for managing content and functions related to the eco-friendly driving platform of electric converted motorcycles. On the aforementioned homepage, management of authority (e.g., creation of administrators and granting of differential permissions), purchase management (e.g., management of credit holdings and purchase / sale information for electric converted motorcycles), charging station management (e.g., management of charging station lists), repair shop management (e.g., management of repair shop lists), security management (e.g., blocking remote access by general users through registration of allowed IPs), bulletin board management (e.g., management of the homepage bulletin board), and statistics inquiry (e.g., statistics on the number of contracts signed by year / technology and functions to view lists of institutional information) may be possible.

[0070] FIG. 2 is a block diagram of a power management module and a battery according to one embodiment.

[0071] Referring to FIG. 2, the electric modified motorcycle (110) may include a power management module (111) and a battery (112).

[0072] The power management module (111) may include a charging circuit (211), a power regulator (212), and a power gauge (213). The charging circuit (211) can charge the first battery (112) using power supplied to the electric modified motorcycle (110) from an external power source. In one embodiment, the charging circuit (211) can select a charging method (e.g., normal charging or fast charging) based on at least some of the types of the external power source (e.g., power adapter or wireless charging), the amount of power available from the external power source, or the attributes of the first battery (112), and can charge the first battery (112) using the selected charging method. The external power source may be wired to the electric modified motorcycle (110), for example, through a connection terminal, or wirelessly connected through an antenna module.

[0073] The power regulator (212) can generate multiple powers having different voltage or different current levels by adjusting the voltage level or current level of the power supplied from, for example, an external power source or a first battery (112). The power regulator (212) can adjust the power of the external power source or the first battery (112) to a voltage or current level suitable for each of the components included in the electric modified motorcycle (110). In one embodiment, the power regulator (212) may be implemented in the form of a low drop-out (LDO) regulator or a switching regulator. The power gauge (213) can measure usage status information for the battery (120) (e.g., battery capacity, number of charge / discharge cycles, voltage, or temperature).

[0074] A power management module (111) can determine battery status information (e.g., lifespan, overvoltage, undervoltage, overcurrent, overcharge, overdischarge, overheating, short circuit, or swelling) related to the charging of the first battery (112) based at least part of the measured usage status information, using, for example, a charging circuit (211), a power regulator (212), and a power gauge (213). The power management module (111) can determine whether the first battery (112) is normal or abnormal based at least part of the determined battery status information. If the condition of the first battery (112) is determined to be abnormal, the power management module (111) can adjust the charging of the first battery (112) (e.g., reducing the charging current or voltage, or stopping the charging). In one embodiment, at least some of the functions of the power management module (111) may be performed by an external control device (e.g., the processor (113) of FIG. 1).

[0075] The first battery (112) may include a battery protection circuit module (PCM) (221). The battery protection circuit (221) may perform one or more of various functions (e.g., a pre-shutdown function) to prevent performance degradation or burnout of the first battery (112). The battery protection circuit (221) may be configured as at least part of a battery management system (BMS) capable of performing various functions, including, additionally or substantially, cell balancing, battery capacity measurement, charge / discharge cycle measurement, temperature measurement, or voltage measurement.

[0076] According to one embodiment, at least a portion of the usage status information or battery status information of the first battery (112) may be measured using a corresponding sensor (e.g., a temperature sensor) or a power gauge (213) among the sensor modules. In one embodiment, the corresponding sensor among the sensor modules may be included as part of the battery protection circuit (221) or may be placed near the first battery (112) as a separate device.

[0077] FIG. 3 is a schematic diagram illustrating the components of a battery station according to one embodiment. As illustrated, the battery station (300) includes a processor (301), memory (303), user interface (305), communication component (307), battery management component (309), instruction management / simulation component (310), one or more sensors (311), storage component (313), and charging component (315) connected to eight battery slots (317a-n). The processor (301) is configured to interact with the memory (303) and other components (e.g., components (305-317)) in the battery station (300). The memory (303) is connected to the processor (301) and is configured to store instructions for controlling other information or other components in other battery stations (300).

[0078] The user interface (305) is configured to interact with the user (e.g., by receiving user input and providing information to the user). In some embodiments, the user interface (305) may be implemented as a touchscreen display. In other embodiments, the user interface (305) may include other suitable user interface devices. The storage component (313) is configured to temporarily or permanently store information, data, files, or signals associated with the battery station (300) (e.g., information measured by the sensor (313), information collected by the battery, reference information, charging commands, user information, etc.). The communication component (307) is configured to communicate with other systems (e.g., electric modified motorcycle (110), server (33) and / or other battery station) and other devices (e.g., mobile terminal (32)).

[0079] The battery management component (309) is configured to manage and control batteries located in battery slots (317a-n). In some embodiments, the battery management component (309) may manage batteries based on commands from the server (33) (e.g., the aforementioned battery management plan). In some embodiments, the battery management component (309) may manage batteries based on predetermined commands or instructions stored in the battery station (300) (e.g., the storage component (313)). In some embodiments, the battery management component (309) may periodically communicate with the server (33) to request update commands.

[0080] In some embodiments, the battery management component (309) may be configured to collect information regarding a battery located in the battery slot (317a-n), information regarding the battery station (300), information regarding at least one power source (35), information regarding a user (e.g., information received from a mobile device (32) via a communication component (307)), and / or information regarding the vehicle system (30). The battery management component (309) may transmit or upload the collected information to a server (33) for subsequent analysis or processing.

[0081] The command management / simulation component (310) is configured to manage a set of operation commands (e.g., some lightweight / fast algorithms) on which the battery station (300) manages, controls, charges, and / or maintains the battery located in the battery slot (317a-n). In some embodiments, the command management / simulation component (310) is configured to verify and implement a battery management plan (e.g., how / when to charge one or more batteries) from the server (33). In some embodiments, the battery management plan may be verified based on an aging policy (e.g., the battery management plan is valid for 12 hours after being generated or issued by the server (33)). When the battery management plan is verified, it is implemented by the battery station (300). If the battery management plan is not verified (e.g., expired), the battery station (300) may manage the battery based on default rules (e.g., a set of operation commands predetermined by the battery station 300). In some embodiments, the default rules for each battery station may differ (e.g., depending on the location of the battery station, predicted battery demand, etc.). In some embodiments, the instruction management component (310) may be configured to manage, maintain, and update a set of instructions stored in the battery station (300) (e.g., in the storage component (313)).

[0082] In some embodiments, the command management / simulation component (310) is configured to perform a simulation of a new or updated battery management plan so that the battery station (300) can locally determine whether to implement the new or updated battery management plan. For example, another battery station is taken offline for regular maintenance. The server (33) generates an updated battery management plan for the battery station (300). For example, the server (33) determines that taking the battery station (300) offline increases the battery demand for the battery station (300). Accordingly, the server (33) provides the updated battery management plan to the battery station (300).

[0083] After receiving the updated battery management plan, the simulation component (310) performs a simulation of the updated battery management plan. In some embodiments, the simulation may be performed by a server. The simulation is performed as a background process that does not substantially interfere with the implementation of the existing battery management plan. In some embodiments, the simulation includes simulating the charging process for batteries located at the battery station based on the updated battery management plan. In some embodiments, the simulation includes simulating whether implementing the updated battery management plan can generate a sufficient number of charged batteries to meet actual demand. For example, due to increased expected demand, the updated battery management plan requires the battery station (300) to charge the batteries at an increased charging rate faster than the normal rate (when the existing battery management plan is used). After a certain period of time (e.g., 12 hours), a simulation result is generated (e.g., charging at the increased charging rate results in a temperature increase of 5 degrees Celsius for the entire station). The simulation result is compared with the actual demand. For example, actual demand indicates that using a normal rate to charge the battery satisfies the actual demand over the past 12 hours. In this embodiment, the battery station (300) may decide not to implement an updated battery management plan.

[0084] The sensor (311) is configured to measure information associated with the battery station (300) (e.g., operating temperature, environmental conditions, power connection, network connection, etc.). Additionally, the sensor (311) may be configured to monitor the battery located in the battery slot (317a-n). The measured information may be transmitted to the battery management component (309) and the server (33) for subsequent analysis.

[0085] The charging component (315) is configured to control the charging process for each of the batteries located in the battery slots (317a-n). In some embodiments, the battery station (300) may include a different number of battery slots. The battery slots (317a-n) are configured to accommodate and charge batteries located and / or locked inside. The charging component (315) receives power from the power source (35) and then uses the power to charge the batteries located in the battery slots (317a-n) based on a predetermined battery management plan received from the server (33) or stored in the storage component (313). In some embodiments, the battery management plan may be determined based on a battery demand forecast generated by the server (33).

[0086] In some embodiments, the battery management plan includes charging the battery to a full-charge point (e.g., 98% of the full charge capacity). In these embodiments, the charging component (315) will stop the charging process when the battery is charged to the full-charge point. In some embodiments, the battery station (300) may control or adjust the charging voltage during the charging process performed by the charging component (315).

[0087] In some embodiments, when a user places a battery in one of the battery slots (317a-n), the battery station (300) can detect the presence of the battery and pull information stored in memory associated with the battery. For example, a battery management component (309) can pull information associated with the battery (e.g., battery usage history, battery identity, charging cycle, full charge capacity, vehicle information of the electric modified motorcycle (110) associated with the inserted battery, user activity involving the battery, etc.) from the battery memory connected to the inserted battery or within it. In some embodiments, information within the battery memory can be transmitted to a server (33) via a communication component.

[0088] FIG. 4 is a cross-sectional view of a coin-type hybrid ion capacitor including a roll-type electrode structure according to one embodiment. FIG. 5 is an exploded cross-sectional view of a coin-type hybrid ion capacitor including a roll-type electrode structure according to one embodiment. FIG. 6 is a schematic diagram illustrating a roll-type electrode structure according to one embodiment.

[0089] According to one embodiment, the first battery (112) (or the second battery (121)) may include a hybrid ion capacitor (400) configuration. The hybrid ion capacitor (400) may include an electrode structure (410), an outer case (420), a cap (430), and a gasket (440).

[0090] According to one embodiment, the electrode structure (410) may be configured as a roll type by sequentially stacking and coiling a first electrode (414) containing an electrode active material, a separator (415), and a second electrode (416) containing an electrode active material.

[0091] According to one embodiment, the outer case (420) accommodates the electrode structure (410) inside, has an opening formed on one side, and may include a first insulating plate (421) on the inner side.

[0092] According to one embodiment, the cap (430) covers the opening of the outer case (420) and may include a second insulating plate (431) on the inner side.

[0093] According to one embodiment, the gasket (440) can secure and seal the outer case (420) and the cap (430).

[0094] According to one embodiment, the first current collector (411) has both ends in contact with the first electrode (414) and the outer case (420) to electrically connect the first electrode (414) and the outer case (420).

[0095] According to one embodiment, the second current collector (412) has both ends in contact with the second electrode (416) and the cap (430) to electrically connect the second electrode (416) and the cap (430).

[0096] According to one embodiment, the length of the separator (415) may be formed to a length specified to surround the outer electrode of the electrode structure (410). Additionally, the separator (415) may be in the form of a coin cell. That is, the separator (150) may be formed to be long enough to wrap around the negative electrode, which is the first electrode (414), at least once. According to the above configuration, the configuration of the electrode structure (410) can be simplified by including only one separator (150), and the capacity can be maximized. Furthermore, the separator (150) may be formed to have a width and length greater than the negative electrode, which is the first electrode (414), and the positive electrode, which is the second electrode (416). Also, the first electrode (414) may be formed to have a longer length than the second electrode (416). According to the above configuration, damage to the electrode can be prevented in advance even during clamping.

[0097] According to the above configuration, it is possible to achieve excellent capacitance retention while simultaneously reducing charging time. Furthermore, by providing a hybrid ion capacitor with high lifespan, high output, and high energy density, it can be effectively utilized in electronic devices and the like. While maintaining the advantages of conventional coin cell capacitors, such as the ease of application in compact and lightweight digital devices, it is possible to overcome the limitations of conventional coin cell capacitors, which have low capacitance retention and stability.

[0098] According to one embodiment, the cathode, which is the first electrode (414), may be formed in various forms of a cathode material by mixing a cathode active material, a binder, a conductive material, and a dispersion medium. Here, it may be suitable to add the cathode material such that the conductive material is 2 to 20 parts by weight and the binder is 2 to 10 parts by weight per 100 parts by weight of activated carbon. The content of the dispersion medium is not particularly limited, but may be added in an amount of 200 to 300 parts by weight per 100 parts by weight of activated carbon. However, the composition of the first electrode (414) is not limited thereto. For example, the cathode active material in the cathode, which is the first electrode (414), may be a mixture of one or more of activated carbon, soft carbon, hard carbon, and graphite.

[0099] The above activated carbon is not particularly limited and any activated carbon used in general electrode manufacturing may be used. For example, coconut shell-based carbonized activated carbon, phenol resin-based carbonized activated carbon, etc., may be used, including partially crystalline activated carbon. It is preferable that the specific surface area of ​​the activated carbon powder used be 300 to 2500 m² / g. To facilitate electrode molding and dispersion, it may be suitable to use activated carbon powder with a particle size in the range of 0.9 to 20 μm.

[0100] The above conductive material is not particularly limited as long as it is an electronically conductive material that does not cause chemical changes, and examples include natural graphite, artificial graphite, carbon black, acetylene black, Ketjenblack, Super-P, Denka black, carbon fiber, metal powder or metal fiber such as copper, nickel, aluminum, and silver.

[0101] In addition, the binder may be used by mixing one or more types selected from polytetrafluoroethylene (PTFE), polyvinylidenefloride (PVdF), carboxymethylcellulose (CMC), polyvinyl alcohol (PVA), polyvinyl butyral (PVB), poly-N-vinylpyrrolidone (PVP), styrene butadiene rubber (SBR), polyamide-imide, polyimide, etc.

[0102] The above dispersion medium may use organic solvents such as ethanol (EtOH), acetone, isopropyl alcohol, methylpyrrolidone (NMP), propylene glycol, or water.

[0103] Since the above cathode material is in a paste-like state, uniform mixing (complete dispersion) may be difficult, such as with a planetary mixer

[0104] A cathode material suitable for electrode manufacturing can be obtained by stirring for a predetermined time (e.g., 10 minutes to 12 hours) using a mixer. Mixers such as planetary mixers enable the production of a uniformly mixed cathode material.

[0105] Although not limited thereto, the first electrode (414), which is the negative electrode, may be formed into a sheet-like electrode shape by compressing a negative electrode material, formed into an electrode shape by coating a metal foil on both sides with a negative electrode material, or formed into an electrode shape by making a negative electrode material into a sheet shape and attaching it to a metal foil.

[0106] A cathode is manufactured by subjecting the cathode shape prepared as described above to a drying process. The drying process is performed at a temperature of 100°C to 350°C, preferably 150°C to 300°C. At this time, if the drying temperature is below 100°C, it is undesirable because it is difficult to evaporate the dispersion medium, and if the drying is at a high temperature exceeding 350°C, it is undesirable because oxidation of the conductive material may occur. Therefore, it may be appropriate for the drying temperature to be at least 100°C and not exceed 350°C. Furthermore, it may be appropriate to carry out the drying process at the above temperatures for about 10 minutes to 6 hours. Such a drying process dries the cathode material (evaporates the dispersion medium) and simultaneously binds the powder particles, thereby improving the strength of the carbon-based electrode serving as the cathode.

[0107] Meanwhile, the positive electrode, which is the second electrode (416), may be formed in various forms by mixing a positive electrode active material containing lithium or sodium transition metal oxide and activated carbon, a binder, a conductive material, and a dispersion medium.

[0108] The above-mentioned cathode material may be prepared by adding 100 parts by weight of a cathode active material, 2 to 15 parts by weight of a conductive material and 2 to 10 parts by weight of a binder to 100 parts by weight of the cathode active material, and the above-mentioned dispersion medium may be prepared in an amount of 200 to 300 parts by weight to 100 parts by weight of the cathode active material.

[0109] The above transition metal oxide may be a composite metal oxide having a layered structure, a spinel structure, or an olivine structure containing lithium and a transition metal. The above transition metal may be at least one metal selected from the group consisting of titanium (Ti), vanadium (V), manganese (Mn), iron (Fe), cobalt (Co), aluminum (Al), and nickel (Ni). Examples of such lithium transition metal oxides include LiMn2O4, LiCoO2, LiNi1 / 3Co1 / 3Mn1 / 3O2, LiNixCoxAlxO2, etc. The specific surface area of ​​the above lithium transition metal oxide may be in the range of 0.1 to 100 m² / g.

[0110] When only lithium transition metal oxides are used as the positive electrode active material, output asymmetry occurs between the positive and negative electrodes because the positive electrode generates capacity through a mechanism utilizing chemical reactions. In other words, as chemical reactions occur in the positive electrode where lithium transition metal oxides are used and physical reactions occur in the negative electrode where activated carbon is used, output asymmetry occurs between the positive and negative electrodes. Consequently, a relative voltage shock is applied to the carbon-based negative electrode, which limits the use of hybrid ion capacitors at high output and high voltages and may lead to reliability issues.

[0111] To suppress the output asymmetry described above and improve cell capacity to improve the withstand voltage characteristics and output characteristics of the hybrid ion capacitor cell, activated carbon is used as a positive electrode active material together with lithium transition metal oxide. The activated carbon powder used as the positive electrode active material is coconut shell-based activated carbon, phenol resin-based activated carbon, coke-based activated carbon, or a mixture thereof, and it may be suitable to use activated carbon powder having a specific surface area of ​​1,000 to 2,500 m² / g.

[0112] The activated carbon powder used as the cathode active material may be suitablely contained in an amount of 1 to 30 parts by weight per 100 parts by weight of the cathode active material. If the content of the activated carbon powder used as the cathode active material is less than 1 part by weight, the effect of suppressing output asymmetry is weak, and if it exceeds 30 parts by weight, the effect of suppressing output asymmetry can no longer be expected, and since the energy density of the activated carbon is insufficient compared to the lithium transition metal oxide, the efficiency of the hybrid system is significantly lost due to capacity reduction. Therefore, it is preferable that the weight ratio of the lithium transition metal oxide to the activated carbon powder (lithium transition metal oxide: activated carbon powder) in the cathode active material be in the range of 99:1 to 70:30.

[0113] Instead of lithium, sodium, which is abundant and inexpensive, can be included as the cathode active material.

[0114] The above conductive material is not particularly limited as long as it is an electronically conductive material that does not cause chemical changes, and examples include natural graphite, artificial graphite, carbon black, acetylene black, Ketjenblack, Super-P, Denka black, carbon fiber, metal powder or metal fiber such as copper, nickel, aluminum, and silver.

[0115] The above binder may be used by mixing one or more types selected from polytetrafluoroethylene (PTFE), polyvinylidenefloride (PVdF), carboxymethylcellulose (CMC), polyvinyl alcohol (PVA), polyvinyl butyral (PVB), poly-N-vinylpyrrolidone (PVP), styrene butadiene rubber (SBR), polyamide-imide, polyimide, etc.

[0116] The above dispersion medium may use organic solvents such as ethanol (EtOH), acetone, isopropyl alcohol, methylpyrrolidone (NMP), propylene glycol (PG), or water.

[0117] Since the anode material is in a paste-like state, it may be difficult to achieve uniform mixing (complete dispersion). However, by using a mixer such as a planetary mixer and stirring for a predetermined time (e.g., 10 minutes to 12 hours), an anode material suitable for electrode manufacturing can be obtained. A mixer such as a planetary mixer enables the production of a uniformly mixed anode material.

[0118] Although not limited thereto, the anode, which is the second electrode (416), may be formed into a sheet-like electrode shape by compressing an anode material, formed into an electrode shape by coating both sides of a metal foil with an anode material, or formed into an electrode shape by making an anode material into a sheet shape and attaching it to a metal foil.

[0119] According to the above configuration, a roll-type electrode structure (410) can be easily formed.

[0120] It may be suitable to manufacture the anode material by double-sided coating it onto a metal foil such as aluminum foil, aluminum etching foil, or aluminum perforated foil, or by rolling the anode material into a sheet (rubber type) and attaching it to a metal foil to form an anode shape. The term "aluminum etching foil" refers to aluminum foil that has been etched into an uneven shape. The perforations of the aluminum perforated foil are perforated with a diameter of several micrometers and a spacing of several millimeters. When using perforated foil, the amount of binder can be reduced, and in the case of a double-sided electrode, the active material powder particles on both sides can be bonded together, which is advantageous for reducing resistance and improving long-term reliability.

[0121] An anode is manufactured by subjecting the anode shape prepared as described above to a drying process. The drying process is performed at a temperature of 100°C to 350°C, preferably 150°C to 300°C. At this time, if the drying temperature is below 100°C, it is undesirable because it is difficult to evaporate the dispersion medium, and if the drying temperature exceeds 350°C, it is undesirable because oxidation of the conductive material may occur. Therefore, it may be appropriate for the drying temperature to be at least 100°C and not exceed 350°C. Furthermore, it may be appropriate to carry out the drying process at the above temperatures for about 10 minutes to 6 hours. Such a drying process dries the anode material (evaporates the dispersion medium) and simultaneously binds the powder particles, thereby improving the strength of the anode.

[0122] The separator (415) provided between the first electrode (414) and the second electrode (416) serves to prevent a short circuit between the first electrode (414) and the second electrode (416). The separator (415) is not particularly limited to any separator commonly used in the battery and capacitor field, such as polyethylene nonwoven fabric, polypropylene nonwoven fabric, polyester nonwoven fabric, polyacrylonitrile porous separator, poly(vinylidene fluoride) hexafluoropropane copolymer porous separator, cellulose porous separator, kraft paper, or rayon fiber.

[0123] FIG. 7 is a drawing illustrating a case of a battery that can be mounted on an electric modified motorcycle according to one embodiment. FIG. 8 is a drawing illustrating components of a battery pack according to one embodiment. FIG. 9 is a drawing illustrating a front view of a battery pack according to one embodiment.

[0124] According to one embodiment, the battery (700) (e.g., first battery (112) and second battery (121)) may include a case (710) and a battery pack (720). In various embodiments, the battery (700) may omit the case (710) among the components or additionally include other components. For example, the battery (700) may further include a thermal expansion member (730) that performs thermal expansion in an abnormal temperature range (e.g., 70°C or higher) and a battery protection circuit (740) (e.g., BMS) that performs at least one of various functions to prevent performance degradation or burnout of the battery (700).

[0125] According to one embodiment, the case (710) may take a corresponding shape that can be mechanically coupled with some components (e.g., a saddle portion) of the electric modified motorcycle (110). For example, the case (710) may be coupled inside the saddle to correspond to the saddle structure (e.g., an L-shape) of the electric modified motorcycle (110). A handle (711) for opening or closing a cover that opens and closes the internal space of the case may be formed on the upper side (e.g., in the +z-axis direction) of the case (710).

[0126] According to one embodiment, the battery pack (720) may include a first battery module (721) and a second battery module (722). The first battery module (721) and the second battery module (722) may be mechanically and electrically connected with the connecting member (723) as the central axis. That is, the first battery module (721) and the second battery module (722) are mechanically connected or combined to form an 'L' shape through the connecting member (723), while simultaneously being electrically connected to each other. For example, the first battery module (721) and the second battery module (722) may be arranged at right angles with the connecting member (723) as the central axis to correspond to the shape of the case (710), and may have an electrical connection relationship (e.g., a series connection relationship) with each other. However, the shape of the battery pack (720) is not limited to this. In various embodiments, the battery pack (720) may form any one of the shapes of an L-shape, a C-shape, a square shape, and an L-shape as the same battery module as the first battery module (721) and the second battery module (722) is added. Here, a connecting member (723) may be shared with the battery modules in contact with each other at each of the bending parts of the shapes.

[0127] As described above, by appropriately combining or integrating basic units of the 'ㄱ' shape using the 'ㄱ' shape as a basic unit, a battery (e.g., a first battery (112) and a second battery (121)) can be made having a shape that corresponds to a slot, which is a space provided within the electric modified motorcycle, and can be mounted and seated within a specific slot of the electric modified motorcycle. The elements for making this battery are a first battery module (721), a second battery module (722), and a connecting member (723).

[0128] According to one embodiment, the first battery module (721) may include a plurality of first battery cells (721a). The plurality of first battery cells (721a) may be composed of a plurality of first battery cell arrays aligned in a first direction (e.g., +y-axis direction). Here, the plurality of first battery cell arrays may be connected in parallel with each other. The number of parallel connections may vary depending on the shape and size of the space where the previously described electric modified motorcycle is mounted, and the size and shape of the battery cells.

[0129] According to one embodiment, the first battery cells (721a) included in each of the plurality of first battery cell arrays may be arranged in a second direction (e.g., -z-axis direction) and connected in series with each other. For example, one electrode (e.g., -x-axis direction) of each of the first battery cells (721a) included in one first battery cell array may form a pair of first electrodes (721b) including a positive electrode and a negative electrode with the neighboring first battery cells (721a), and the other electrode (e.g., +x-axis direction) of each of the first battery cells (721a) included in the one first battery cell array may form a pair of second electrodes (721c) including a positive electrode and a negative electrode with the neighboring first battery cells (721a). Accordingly, an electrode structure in which a positive electrode and a negative electrode are alternately formed may be formed on each of the first battery cells (721a) included in the one first battery cell array.

[0130] According to one embodiment, the second battery module (722) may include a plurality of second battery cells (722a). The plurality of second battery cells (722a) may be composed of a plurality of second battery cell arrays aligned in a third direction (e.g., +y-axis direction). Here, the plurality of second battery cell arrays may be connected in parallel with each other.

[0131] According to one embodiment, the second battery cells (721a) included in each of the plurality of second battery cell arrays may be arranged in a fourth direction (e.g., +x axis direction) and connected in series with each other. For example, one electrode (e.g., -z axis direction) of each of the second battery cells (722a) included in one second battery cell array may form a pair of third electrodes (722b) including a positive and a negative electrode with the adjacent second battery cells (722a), and the other electrode (e.g., +z axis direction) of each of the second battery cells (722a) included in the one second battery cell array may form a pair of fourth electrodes (722c) including a positive and a negative electrode with the adjacent second battery cells (722a). Accordingly, an electrode structure in which a positive and a negative electrode are alternately formed may be formed on each of the two sides of the second battery cells (722a) included in the one second battery cell array.

[0132] According to one embodiment, the other electrode (e.g., +x-axis direction) of the first battery cell (721a) located at the end near the second battery module (722) among the first battery cells (721a) included in the first battery cell array may form a pair of fifth electrodes (723a) including a positive electrode and a negative electrode, with the other electrode (e.g., +z-axis direction) of the second battery cell (722a) located at the end near the first battery module (721) among the second battery cells (722a) included in the second battery cell array.

[0133] According to one embodiment, the connecting member (723) can electrically connect the first battery cell array and the second battery cell array. The connecting member (723) may be positioned at the ends where the first battery cell array and the second battery cell array meet at a right angle. For example, the connecting member (723) may be positioned in a shape (e.g., 'T' shape, 'L' shape, or 'C' shape) that extends from the electrode portion (e.g., positive portion) of the first battery cell (721a) located at the end of the first battery cell array to the electrode portion (negative portion) of the second battery cell (722a) located at the end of the second battery cell array, so as to correspond to the shape of the ends that meet at a right angle.

[0134] Meanwhile, among the first battery cells (721a) included in the first battery cell array, the other electrode (721d) located at the end far from the second battery module (722) can form a parallel structure with another first battery cell array. Additionally, among the second battery cells (722a) included in the second battery cell array, the other electrode (722d) located at the end far from the first battery module (721) can form a parallel structure with another second battery cell array.

[0135] According to one embodiment, the details regarding the structure, electrical characteristics, and design of the battery (700) described above may apply to both the first battery (112) and the second battery (121).

[0136] As described above, although the present invention has been explained by limited embodiments and drawings, the present invention is not limited thereto, and it is obvious that various modifications and variations are possible within the scope of the technical spirit of the present invention and the equivalent scope of the claims described below by those skilled in the art to which the present invention belongs.
