The remote server marks the battery of the electric vehicle according to the vehicle identification data or the battery identification data, and the marked battery cannot be used for a battery exchange operation.
[0016] The above method of the present invention can exist in the form of program code. When the program code is loaded and executed by a machine, the machine becomes a device for implementing the present invention. Therefore, another object of the present invention is to provide a computer program product as described above.
[0017] Therefore, the computer program product of the present invention is loaded into a machine to execute a battery management method for an electric vehicle, and is applicable to an electric vehicle.

[0053] Figure 4 FIG. 1 is a flow chart showing a battery management method for an electric vehicle according to another embodiment of the present invention. In this embodiment, the marked batteries will be further managed.
[0054] First, as in step S410, a battery energy station is used to receive the battery corresponding to the electric vehicle. It is reminded that the battery energy station can have multiple batteries for providing to at least one power-consuming device, such as an electric motorcycle or an electric car. The user can place the battery into the battery storage slot of the battery energy station to perform a battery exchange operation. Then, as in step S420, the battery energy station reads the battery identification data corresponding to the battery and transmits the battery identification data to the remote server through a network. Similarly, in some embodiments, the network can be a wired network, a telecommunications network, and a wireless network, such as Bluetooth, Wi-Fi network, etc. Afterwards, as in step S430, the battery energy station receives an instruction from the remote server through the network, and locks the battery in the battery energy station according to the instruction. It is worth noting that after the remote server receives the battery identification data corresponding to the battery, it will check whether the battery corresponding to this battery identification data has been marked. When the battery has been marked, an instruction is sent to the battery energy station to instruct the battery energy station to lock the battery and cancel the battery exchange operation.
[0055] It must be pointed out that in this case, abnormal conditions of electric vehicles can be set and detected according to different needs and applications.
[0056] Figure 5A method for determining an abnormality of an electric vehicle according to an embodiment of the present invention is shown. In this embodiment, the electric vehicle has a trunk lid. First, as in step S510, the electric vehicle determines whether the trunk lid is opened when the electric vehicle is not opened with a key, or the electric vehicle is not connected to a mobile device. When the trunk lid is opened when the electric vehicle is opened with a key, or the electric vehicle is connected to the mobile device (no in step S520), the process returns to step S510. When the trunk lid is opened when the electric vehicle is not opened with a key, or the electric vehicle is not connected to the mobile device (yes in step S520), as in step S530, it is determined that an abnormality has occurred in the electric vehicle.
[0057] Figure 6 A method for determining whether an abnormality occurs in an electric vehicle according to another embodiment of the present invention is shown. First, as in step S610, determine whether the electric motorcycle is started without using a key to open it. It is worth noting that in some embodiments, the key can be a physical key, or an electronic device that is wirelessly sensed / connected, such as an induction card or a mobile device. When the electric motorcycle is started by using the key to open it (no in step S620), the process returns to step S610. When the electric motorcycle is started without using the key to open it (yes in step S620), as in step S630, it is determined that an abnormality occurs in the electric vehicle. It must be noted that the aforementioned method for determining whether an abnormality occurs in the electric vehicle is only an embodiment of this case, and the present invention is not limited thereto.
[0058] It is worth noting that in addition to marking the battery when an abnormality occurs in an electric vehicle, this case can also be further applied and managed for electric vehicles.
[0059] Figure 7 A battery management method for an electric vehicle according to another embodiment of the present invention is displayed. When the electric vehicle does not have an abnormality (No in step S710), the judgment of step S710 continues. When the electric vehicle has an abnormality (Yes in step S710), as in step S720, a battery replacement reminder is issued through an output unit of the electric vehicle. Note that in some embodiments, the output unit may include a display unit and / or a pronunciation unit.
[0060] Figure 8 A battery management method for an electric vehicle according to another embodiment of the present invention is shown. When the electric vehicle does not have an abnormality (No in step S810), the determination of step S810 is continued. When the electric vehicle has an abnormality (Yes in step S810), as in step S820, the electric vehicle limits the power output of the battery and / or limits the output of a motor unit of the electric vehicle.
[0061] Fig. 9A battery management method for an electric vehicle according to another embodiment of the present invention is shown. When the electric vehicle does not have an abnormality (No in step S910), the judgment of step S910 is continued. When the electric vehicle has an abnormality (Yes in step S910), as in step S920, the electric vehicle or the remote server transmits warning information to a user device of the electric vehicle, such as a mobile device, through the network. Then, as in step S930, the remote server receives a release command from the user device through the network, and as in step S940, the remote server cancels the labeling of the battery of the electric vehicle in response to the release command. It is reminded that in some cases, the abnormal condition of the electric vehicle may be caused by problems in user operation. At this time, when the user receives the warning information, he can further confirm whether the abnormality really occurs, such as the electric vehicle being stolen or the car box being opened by others. If the abnormality is caused by the user's own operation, the user device can be used to send a release command to cancel the labeling operation of the corresponding battery.
[0062] Therefore, through the battery management method of the electric vehicle and the electric vehicle of this case, the battery of the electric motorcycle can be managed when an abnormality occurs in the electric vehicle, thereby increasing the safety and anti-theft protection of the electric vehicle and its battery.
[0063] The method of the present invention, or a specific form or part thereof, may exist in the form of program code. The program code may be contained in a physical medium, such as a floppy disk, an optical disk, a hard disk, or any other machine-readable (such as computer-readable) storage medium, or a computer program product that is not limited to an external form, wherein when the program code is loaded and executed by a machine, such as a computer, the machine becomes an apparatus for participating in the present invention. The program code may also be transmitted through some transmission medium, such as wires or cables, optical fibers, or any transmission mode, wherein when the program code is received, loaded and executed by a machine, such as a computer, the machine becomes an apparatus for participating in the present invention. When implemented on a general-purpose processing unit, the program code combines with the processing unit to provide a unique device that operates similarly to application-specific logic circuits.
[0064] The computer program product of the present invention is loaded into a machine to execute a battery management method for an electric vehicle, and is applicable to an electric vehicle. The computer program product includes a first program code and a second program code. The first program code is used to detect whether an abnormal state occurs in the electric vehicle. The second program code is used to send a warning message to a remote server through a network when the abnormal state occurs in the electric vehicle, wherein the warning message includes a vehicle identification data corresponding to the electric vehicle, or a battery identification data corresponding to at least one battery of the electric vehicle. The remote server marks the battery of the electric vehicle according to the vehicle identification data or the battery identification data, wherein the marked battery cannot be subjected to a battery exchange operation.
[0065] However, what is described above is only an embodiment of the present invention and should not be used to limit the scope of implementation of the present invention.
