Background Art

[0002] In recent years, with the rise of environmental awareness and the progress of electric vehicle technology, developing electric vehicles powered by electric energy to replace traditional vehicles powered by fossil fuels has gradually become an important goal in the automotive field, thus making electric vehicles more and more popular. In order to increase the range and willingness to use of electric vehicles, many countries or cities have begun to plan to set up charging stations and battery energy stations in public places to provide charging or battery swapping for electric vehicles and / or electric motorcycles, making the use of electric vehicles more convenient.

[0003] Whether it is a charging station or a battery energy station, heat will be generated during the charging operation of the battery. Since electronic devices are prone to anomalies when operating continuously at high temperatures, which will in turn affect their service quality. Therefore, the fans configured inside the device will automatically start at this time to achieve the effect of cooling. Inevitably, the startup of the fans will generate noise, and the higher the fan speed, the greater the noise generated.

[0004] Since the charging stations and battery energy stations, especially the battery energy stations for electric motorcycles, may be located in residential areas to facilitate users to access the batteries. Therefore, how to control the fan speed to avoid the operation noise of the charging stations and battery energy stations causing inconvenience to the nearby residents will become an important topic in the industry.

[0043] Figure 5 Displays a method for controlling the fan speed of a battery energy station according to an embodiment of the present invention. The method for controlling the fan speed of a battery energy station according to an embodiment of the present invention is applicable to a battery energy station for accommodating and charging a plurality of batteries, as Figure 1 shown.

[0044] First, as in step S510, a first fan speed determination rule and a second fan speed determination rule are provided in the battery energy station. Among them, the first fan speed determination rule and the second fan speed determination rule are different, and at least one temperature is defined in each of the first fan speed determination rule and the second fan speed determination rule corresponding to a fan speed. It must be noted that, in some embodiments, the temperatures set when the same fan speed is defined in the first fan speed determination rule and the second fan speed determination rule may be different. In some embodiments, the fan speeds set when the same temperature is defined in the first fan speed determination rule and the second fan speed determination rule may be different. Once again, it should be noted that the fan speed determination rules in the foregoing embodiments are only examples of this case, and the present invention is not limited thereto.

[0045] As in step S520, at least one temperature detector of the battery energy station is used to detect a temperature. It should be noted that there may be multiple charging modules in the battery energy station, and each charging module has a temperature detection unit for detecting a specific temperature corresponding to the charging module. The battery energy station may use the highest specific temperature as the basis for subsequent judgment and management. Then, as in step S530, the battery energy station controls the rotation speed of at least one fan in the battery energy station according to the temperature and the first fan rotation speed judgment rule. After that, as in step S540, the battery energy station determines whether a predetermined condition is satisfied. When the predetermined condition is not satisfied (No in step S540), the process returns to step S520. When the predetermined condition is satisfied (Yes in step S540), as in step S550, the battery energy station controls the rotation speed of the fan in the battery energy station according to the temperature and the second fan rotation speed judgment rule. In other words, the battery energy station determines whether the predetermined condition is satisfied, and automatically switches different fan rotation speed judgment rules to control the rotation speed of the fan in the battery energy station when the predetermined condition is satisfied.

[0046] It should be reminded that the predetermined condition can be designed according to different requirements and applications. This case is not limited to any predetermined condition. Next, two examples of predetermined conditions are given for illustration.

[0047] Figure 6 Fig. shows a method for determining whether a predetermined condition is satisfied according to an embodiment of the present invention. First, as in step S610, a setting position attribute corresponding to the battery energy station is obtained. Then, as in step S620, it is determined whether the setting position attribute corresponding to the battery energy station belongs to a residential area. When the setting position attribute corresponding to the battery energy station does not belong to the residential area (No in step S620), the process ends. When the setting position attribute corresponding to the battery energy station belongs to the residential area (Yes in step S620), as in step S630, a current time is obtained, and it is determined whether the current time falls within a preset time interval, such as 20:00 to 06:00. When the current time does not fall within the preset time interval (No in step S630), the judgment in step S630 continues. When the current time falls within the preset time interval (Yes in step S630), as in step S640, it is determined that the predetermined condition is satisfied.

[0048] Figure 7A method for determining whether a given condition is met according to another embodiment of the present invention is shown. First, as in step S710, an environmental sound is detected by a sound receiving unit of the battery energy station. Next, as in step S720, the battery energy station determines whether a volume of the environmental sound is lower than a given decibel value. When the volume of the environmental sound is not lower than the given decibel value (No in step S720), the process returns to step S710. When the volume of the environmental sound is lower than the given decibel value (Yes in step S720), as in step S730, it is determined that the given condition is met.

[0049] It must be noted that the foregoing example of determining the given condition is only an example of this case, and the present invention is not limited thereto. The given condition can be designed according to different requirements and applications. Therefore, by the method for controlling the fan speed of the battery energy station in this case and the battery energy station thereof, the fan speed of the battery energy station can be automatically controlled when the given condition occurs, and thus the convenience of the user and the impact of noise on the surrounding residents can be taken into account while the system operates stably.

[0050] The method of the present invention, or a specific form or a part thereof, may exist in the form of program code. The program code may be included in a tangible medium, such as a floppy disk, a CD-ROM, a hard disk, or any other machine-readable (such as computer-readable) storage medium, or not limited to the computer program code in an external form. Wherein, when the program code is loaded and executed by a machine, such as a computer, this machine becomes a device for participating in the present invention. The program code can also be transmitted by some transmission media, such as wires or cables, optical fibers, or any transmission form. Wherein, when the program code is received, loaded, and executed by a machine, such as a computer, this machine becomes a device for participating in the present invention. When implemented in a general-purpose processing unit, the program code combined with the processing unit provides a unique device that operates similarly to an application-specific logic circuit.

[0051] Although the present invention has been disclosed in preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be defined by the claims.
