Description

Title of the invention: METHODS AND SYSTEMS FOR MANAGING BATTERY CHARGING DATA FOR ELECTRIC VEHICLES Technical field

[0001] The invention relates generally to methods and systems for managing battery charging data, and, more particularly, to methods and systems that can determine whether an anomaly has occurred in the battery charging status of an electric vehicle. Technical background

[0002] Recently, with the increasing awareness of environmental protection and the technological advancement of electric vehicles, the development of electric vehicles powered by electric energy to replace traditional vehicles using fossil fuels has gradually become an important objective in the automobile sector, thus making electric vehicles increasingly popular. In order to increase the driving range and willingness to use electric vehicles, many countries or cities have begun to install charging stations and battery energy stations in public places to enable the batteries of electric vehicles and / or electric motorcycles to be charged or exchanged, thus making the use of electric vehicles more convenient.

[0003] Generally, batteries represent one of the largest costs for manufacturers, and rechargeable batteries have a relatively limited lifespan. For some electric vehicles, such as electric motorcycles, when the battery power is insufficient, the power difference between each battery is too large and / or the remaining lifespan of the individual batteries is very different, if a combination of these batteries is used to start the electric vehicle, this will have an impact on the operation or lifespan of the vehicle or the battery itself.

[0004] In addition, the high cost of batteries is also one of the main reasons for the high maintenance costs of electric motorcycles. If different charging modes can be planned according to users' needs, or even different suppliers can be introduced to join the ecological chain of electric vehicles, it may be possible to moderately reduce the overall maintenance cost of electric motorcycles and strengthen users' willingness to adopt electric motorcycles. In some cases, if users can charge at home, operators can design more favorable plans to encourage users to adopt electric motorcycles in order to reduce the use of public power supply equipment and thus disperse the power supply pressure on the power grid. However, in this case, it is necessary to obtain the user's battery usage and charging status to prevent the user from encountering abnormal conditions during the charging operation. Summary

[0005] Therefore, the objective of the present invention is to provide methods and systems for managing battery charging data for electric vehicles.

[0006] In one embodiment of a battery charging data management method for electric vehicles, an electric vehicle is used to record the mileage of the electric vehicle. Then, a power booster device is used to perform a power booster operation for a battery, the battery being used to supply electric power to the electric vehicle, and the power booster operation comprises a battery charging operation or a battery exchanging operation. The battery or the power booster device is used to record power booster recording data corresponding to the power booster operation, the power booster recording data comprising at least battery identification data of the battery and power booster information.Then, a remote server obtains the battery power boosting record data and mileage of the electric vehicle, and accordingly determines whether the electric vehicle has an abnormal power boosting state.

[0007] One embodiment of a battery charging data management system for electric vehicles includes an electric vehicle, a battery, a power booster device, and a remote server. The electric vehicle records the mileage of the electric vehicle. The battery provides electrical power to the electric vehicle. The power booster device couples to the battery to perform a power booster operation corresponding to the battery. The power booster operation includes a charging operation or a battery exchange operation, and the battery or the power booster device records power booster recording data of the power booster operation, the power booster recording data including at least battery identification data of the battery, and power booster information.The remote server obtains the battery power boosting record data and mileage of the electric vehicle, and determines whether the electric vehicle has an abnormal power boosting state based on the battery power boosting record data and mileage of the electric vehicle.

[0008] In some embodiments, the remote server further calculates an amp-hour consumption based on the mileage of the electric vehicle, determines whether the power top-up information is within a predetermined tolerance range of the amp-hour consumption, and determines that the electric vehicle has the abnormal power top-up state when the power replenishment information is not within the predetermined tolerance range of the amp-hour consumption.

[0009] In some embodiments, the remote server further generates a warning notification, or sends the warning notification via a network to a user device linked to the battery identification data when the power boost information is not within the predetermined tolerance range of the amp-hour consumption.

[0010] In some embodiments, the battery electrically couples to the electric vehicle to provide electrical power to the electric vehicle, and transmits the boost recording data to the electric vehicle. The electric vehicle transmits the boost recording data and mileage to the remote server via a network. The electric vehicle directly transmits the boost recording data and mileage to the remote server via the network, or connects to a mobile device via the network, and transmits the boost recording data and mileage to the remote server via the mobile device.

[0011] In some embodiments, a wireless connection unit of the battery transmits the power boost recording data to the remote server via a wireless network. The electric vehicle transmits the mileage to the remote server via a network. The electric vehicle directly transmits the mileage to the remote server via the network, or connects to a mobile device via the network, and transmits the mileage to the remote server via the mobile device.

[0012] In some embodiments, the power booster device comprises the electric vehicle, a home charger, or a battery charging station.

[0013] The methods for managing battery charge data may take the form of program code embedded in a tangible medium. When the program code is loaded and executed by a machine, the machine becomes an apparatus for practicing the disclosed method. Brief description of the drawings

The electric vehicle 140 may record the total mileage of the electric vehicle 140 and / or the distance traveled between each battery charging operation.The battery 110, the power booster device 120 and / or the electric vehicle 140 may be connected to the remote server 130 directly or indirectly via a network, and perform the battery charging data management methods for electric vehicles of the present invention, the details of which will be described later.

[0024] [Fig. 2] is a schematic diagram illustrating an embodiment of power boost recording data collection of the invention. In this embodiment, when performing the corresponding battery power boost operation, the power boost device 120 may record the power boost recording data of the corresponding power boost operation. The power boost device 120 may have network connection capability. The power boost device 120 may transmit the power boost recording data to the remote server 130 via a network 200. It should be noted that, in some embodiments, the network 200 may be a wired network, a telecommunications network, and a wireless network, such as a Bluetooth network, Wi-Fi, etc.As mentioned above, in some embodiments, the power booster device 120 may include an electric vehicle, a home charger, and / or a battery charging station.

[0025] It should be noted that, in some embodiments, when performing the power boost operation of the corresponding battery, the battery 110 may record the power boost recording data of the power boost operation. The battery 110 may include a network connection unit. The battery 110 may connect to a network via the network connection unit and transmit the power boost recording data to the remote server 130 via the network.

[0026] [Fig. 3] is a schematic diagram illustrating another embodiment of power boost recording data collection of the invention.

The mobile device 150 has network connection capability and transmits the power boost recording data and mileage from the electric vehicle to the remote server 130 via a network 300. Similarly, in some embodiments, the network 300 may be a wired network, a telecommunications network, and a wireless network, such as a Bluetooth or Wi-Fi network.It should be noted that, in some embodiments, the remote server 130 may simultaneously manage batteries, electric vehicles and / or power booster devices located at the same location or at different locations.

[0027] [Fig.4] is a flowchart of an embodiment of a method for managing battery charging data for electric vehicles of the invention.

[0028] First, in step S410, an electric vehicle is used to record the mileage of the electric vehicle. It should be noted that, in some embodiments, the aforementioned mileage may be the total mileage of the electric vehicle and / or the distance traveled between each battery charging operation. In step S420, a power booster device is used to perform a power booster operation corresponding to a battery, wherein the power booster operation may comprise a charging operation or a battery exchange operation. Similarly, in some embodiments, the power booster device may comprise an electric vehicle, a home charger, and / or a battery charging station.In step S430, the battery or the power booster device is used to record the power booster recording data of the corresponding power booster operation. In some embodiments, the power booster recording data at least comprises identification data of . battery corresponding to the battery, power booster information and / or device identification data of the power booster device. It should be particularly emphasized that in response to the flexibility of application requirements, the charging modes can be diversified, so the device identification data of the power booster device is relatively large. Through the management of device identification data of power booster devices, more diversified charging modes can be provided. For example, the battery can record data on a charging mode applicable to the corresponding user.The charging mode data may record the modes in which the battery can be charged, such as charging in an electric vehicle, charging on a home charger, charging at a battery charging station, and battery exchange at a battery charging station, or a combination thereof. During the power boost operation, it may be determined whether the battery can be charged on the power boost device based on the charging mode of the battery and the device identification data of the power boost device. Then, in step S440, a remote server is used to obtain the power boost record data of the corresponding battery and the mileage of the corresponding electric vehicle.Next, in step S450, it is determined whether the electric vehicle has an abnormal power boosting state based on the power boosting record data and the mileage of the corresponding electric vehicle. It should be noted that in some embodiments, when an electric vehicle has an abnormal power boosting state, it may mean that the battery charging situation cannot be accurately recorded or obtained. In some embodiments, when an electric vehicle has an abnormal power boosting state, it may indicate that the user may have committed fraud during the battery charging operation. For example, if a user modifies the power boosting record data by cracking, the actual mileage of the electric vehicle may be inconsistent with the power boosting record data of the corresponding battery.

[0029] [Fig.5] is a flowchart of one embodiment of a method for determining whether abnormal conditions have occurred during the recharging operation.

[0030] Firstly, in step S510, the remote server calculates a consumption in ampere-hours based on the mileage of the corresponding electric vehicle. It should be noted that, as mentioned above, the mileage may be the total driving mileage of the electric vehicle and / or the distance traveled between each battery recharging operation. Then, in step S520, it is determined if the power boost information is within a predetermined tolerance range of the ampere-hour consumption. When the power boost information is within the predetermined tolerance range of the ampere-hour consumption (Yes in step S530), the process ends. In other words, the electric vehicle does not have an abnormal power boost state. When the power boost information is not within the predetermined tolerance range of the ampere-hour consumption (No in step S530), in step S540, the remote server determines that the electric vehicle has an abnormal power boost state. Then, in step S550, the remote server generates a warning notification, or sends the warning notification via a network to a user device linked to the corresponding battery identification data.

[0031] [Fig.6] is a flowchart of an embodiment of a power boost recording data collection method of the invention. In this embodiment, the power boost recording data in the battery can be sent to the electric vehicle, and then sent to the remote server via the electric vehicle.

[0032] First, in step S610, the battery is electrically coupled to an electric vehicle, such as an electric motorcycle, to supply electric power to the electric vehicle. In step S620, the power boosting record data of the corresponding battery is sent (transmitted) to the electric vehicle. As mentioned above, when the power boosting operation of the battery is performed, the power boosting record data of the corresponding power boosting operation is recorded and stored in the battery storage unit. Then, in step S630, the electric vehicle transmits the power boosting record data and the mileage of the corresponding electric vehicle to a remote server via a network.It should be noted that in some embodiments, the electric vehicle may directly send the power boost record data and mileage of the corresponding electric vehicle to the remote server via a network, or the electric vehicle may connect to a mobile device via a network, such as a Bluetooth network, Wi-Fi, and send the power boost record data and mileage to the remote server via the mobile device. It should be noted that in some embodiments, in addition to the battery identification data of the corresponding battery, the device identification data of the power boost device and / or the power boost information, the power boost record data may further comprise a code. vehicle identification, corresponding electric vehicle, and user identification data corresponding to the battery.

[0033] [Fig.7] is a flowchart of another embodiment of a power backup recording data collection method of the invention.

[0034] First, in step S710, a wireless connection unit of the battery is used to transmit the power boost recording data to the remote server via a wireless network. In step S720, the electric vehicle is used to transmit the mileage of the electric vehicle to the remote server via a network. It should be noted that the electric vehicle can directly transmit the mileage to the remote server via the network, or connect to a mobile device via the network and transmit the mileage to the remote server via the mobile device.

[0035] It is recalled that once the remote server receives the power boost recording data and mileage, it can execute related applications, such as determining whether the electric vehicle has an abnormal power boost state.

[0036] Therefore, the methods and system for managing battery charging data for electric vehicles can determine whether the battery charging status of electric vehicles is abnormal, thereby increasing the accuracy of charging record data collection and preventing fraud.

[0037] The methods for managing battery charge data may take the form of program code (i.e., executable instructions) embodied in tangible media, such as floppy disks, CD-ROMs, hard disks, or other machine-readable storage media, such that when the program code is loaded onto and executed by a machine, such as a computer, the machine becomes an apparatus for performing the methods. The methods may also be implemented as program code transmitted over some transmission medium, such as electrical wiring or cabling, via optical fibers, or via some other form of transmission, such that when the program code is received and loaded into and executed by a machine, such as a computer, the machine becomes an apparatus for performing the disclosed methods.When implemented on a general-purpose processor, the program code combines with the processor to provide a single device that operates analogously to application-specific logic circuits.

[0038] Although the invention has been described by way of example by means of a preferred embodiment, it should be understood that the invention is not limited thereto. Those skilled in the art in this technology may still make various alterations and modifications without departing from the scope and spirit of this invention. Accordingly, the scope of the present invention will be defined and protected by the following claims and their equivalents.
