Further, the battery storage system 110 may include a charging module corresponding to each of the plurality of batteries 112, and a current upper limit and / or a current lower limit is set for the charging module to charge the corresponding battery. In other embodiments, the energy module can automatically detect the total current supplied from the power distribution network to the battery energy station 100 and transmit information corresponding to the total current to the processing unit 160. The temperature sensor 120 detects temperature. As described above, the battery energy station 100 may include a plurality of charging modules. In other embodiments, each charging module may be provided with a temperature detection unit that detects a predetermined temperature corresponding to the charging module.

[0013] FIG. 4 is a diagram showing a state where a battery energy station according to an embodiment of the present invention is connected to a remote server via the Internet. The battery energy station 100 according to the present embodiment includes a plurality of batteries, which are applied to electric devices and provide the plurality of batteries to at least one type of electric device, for example, an electric bike or an electric vehicle. Since the battery energy station 100 can have a configuration similar to the configuration shown in FIG. 1, a detailed description thereof will be omitted. The battery energy station 100 is connected to the remote server 200 via a network 300 such as a wired network, a communication network, or a wireless network, for example, a Wi-Fi network, using the network connection unit 150.

The battery energy station 100 can perform related operations based on the received information.
[0014] FIG. 5 shows a method for controlling the rotation speed of a fan for a battery energy station according to an embodiment of the present invention. The method for controlling the rotation speed of a fan for a battery energy station according to an embodiment of the present invention can be applied to a battery energy station as shown in FIG. 1 that houses and charges a plurality of batteries.
[0015] Next, a method for controlling the rotational speed of a fan for a battery energy station will be described. First, in step S510, different first and second fan rotational speed determination rules are provided in the battery energy station, and at least one rotational speed of the fan corresponding to the temperature is set in each of the first and second fan rotational speed determination rules. In other embodiments, even if the rotational speeds of the fans in the first and second fan rotational speed determination rules are the same, the temperatures may be set differently. Also, even if the temperatures in the first and second fan rotational speed determination rules are the same, the rotational speeds of the fans may be set differently. Note that the fan rotational speed determination rules according to the above-described embodiments are merely examples, and the present invention is not limited thereto.
[0016] In step S520, the temperature is detected using at least one temperature sensor of the battery energy station. Note that the battery energy station may include a plurality of charging modules, and each charging module is provided with a temperature detection unit, and a predetermined temperature corresponding to the charging module can be detected. The battery energy station uses the highest of the predetermined temperatures as a reference when making subsequent judgments and executing management. In the next step S530, the battery energy station controls the rotation speed of at least one fan in the battery energy station based on the temperature and the first fan rotation speed determination rule. In the next step S540, it is determined whether the battery energy station satisfies a predetermined condition. If the result is that the predetermined condition is not satisfied (that is, if the result of step S540 is NO), the process returns to step S520. On the other hand, if the result is that the predetermined condition is satisfied (that is, if the result of step S540 is YES), the process proceeds to step S550. In the next step S550, the battery energy station controls the rotation speed of the fan in the battery energy station based on the temperature and the second fan rotation speed determination rule. In other words, the battery energy station determines whether a predetermined condition is satisfied. If it is satisfied, it automatically switches to a different fan rotation speed determination rule and controls the rotation speed of the fan in the battery energy station.
[0017] Note that the predetermined condition can be set according to different needs and applications. The present invention is not limited to any specific predetermined condition. Next, two predetermined conditions will be described as examples.
[0018] Figure 6 shows a method for determining whether a predetermined condition is satisfied in an embodiment of the present invention. In step S610, a location attribute corresponding to the battery energy station is obtained. In the next step S620, it is determined whether the location attribute corresponding to the battery energy station is a residential area. If the location attribute corresponding to the battery energy station is not a residential area (that is, if the result of step S620 is NO), the process ends. On the other hand, if the location attribute corresponding to the battery energy station is a residential area (that is, if the result of step S620 is YES), the process proceeds to step S630. In the next step S630, the current time is obtained, and it is determined whether the current time corresponds to a default time period, for example, 20:00 to 6:00. If the current time does not correspond to the time period (that is, if the result of step S630 is NO), the determination in step S630 continues. On the other hand, if the current time corresponds to the time period (if the result of step S630 is YES), the process proceeds to step S640, and it is determined that a predetermined condition is satisfied.
[0019] Figure 7 shows a method for determining whether a predetermined condition is satisfied in another embodiment of the present invention. In step S710, environmental sound is detected using the sound receiving unit of the battery energy station. In the next step S720, it is determined whether the volume of the environmental sound detected by the battery energy station is lower than a predetermined decibel. If the volume of the environmental sound is not lower than the predetermined decibel (that is, if the result of step S720 is NO), the process returns to step S710. On the other hand, if the volume of the environmental sound is lower than the predetermined decibel (that is, if the result of step S720 is YES), the process proceeds to step S730, and it is determined that a predetermined condition is satisfied.
[0020] Still, the determination of the above-described predetermined conditions is merely an example, and the present invention is not limited thereto. The predetermined conditions can be set according to different needs and applications. Thus, according to the method for controlling the rotational speed of the fan for the battery energy station and the battery energy station of the present invention, in a situation where a predetermined condition occurs, the rotational speed of the fan of the battery energy station can be automatically controlled, and the system can be stably operated. Therefore, the convenience of the user can be improved, and the influence of noise on the surrounding residents can be reduced.
[0021] A form or a part of the method of the present invention may also be realized by a program. The program may be stored in a physical storage medium, such as a floppy disk, a disk, a hard disk, or other machine-readable (e.g., computer-readable) storage devices, or may be a computer program product that is not physical. When the program is loaded into and executed by a device, such as a computer, the device becomes an apparatus for realizing the present invention. The program may also be transmitted via a transmission medium, such as an electric wire, a cable, an optical fiber, or other transmission forms. When the program is received, loaded into, and executed by a device, such as a computer, the device becomes an apparatus for realizing the present invention. Also, when a processing unit is used for general purposes, by applying the program to the processing unit, an operation method similar to the operation of a unique apparatus applying a predetermined logic circuit is provided.
