Description

[Technical Field]

[0001] The present invention relates to a battery charging method and a battery energy station, and more particularly to a hybrid battery charging method and a battery energy station for managing a hybrid battery charging schedule based on the battery state under the assumption of a specific charging current. [Background technology]

[0002] In recent years, with increasing awareness of environmental issues and significant advances in electric vehicle technology, developing electric vehicles powered by electrical energy to replace traditional vehicles powered by fossil fuels has become an important goal in the automotive field, and the adoption rate of electric vehicles is increasing. In order to improve the driving range of electric vehicles and promote their use, many countries and cities have widely installed charging stations and energy stations in public places, providing services for charging and battery swapping for electric cars and electric motorcycles, thereby making the use of electric vehicles more convenient.

[0003] [Patent Document 1] Chinese Patent Application Publication No. 118693811 Summary of the Invention [Problem to be solved by the invention]

[0004] However, as electric vehicles become more widespread, the demand for electricity will also increase. Because strengthening existing power plants and power grids is costly and time-consuming, the burden on the existing power grid to meet the electricity demands of various sectors, such as households, factories, and public places, may increase, leading to more frequent power trips and blackouts. In response to this issue, energy regulation and control agreements can be established between power plants and electricity users (e.g., operators of charging stations and battery energy stations), for example, to manage the power grid based on the required electricity usage. For example, when electricity usage is at a peak, the electric utility can notify its affiliates to reduce their electricity usage needs and encourage them to do so with specific incentives.

[0005] Generally, when the power grid is in an off-peak state of electricity usage, the electricity users, such as charging stations and battery energy stations, can charge in accordance with the charging rules originally designed. For example, when electricity usage is in an off-peak state, a battery energy station can charge the battery stored therein with maximum efficiency. However, when the power grid is in a peak state of electricity usage and needs to meet the energy usage requirements of the electric utility, the electricity users must comply with specific charging rules to meet this. Thus, how to meet the power usage needs of users while maintaining the normal operation of the power grid has become a problem that must be solved in related industries.

[0006] SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a hybrid battery charging method and a battery energy station that can achieve the above-mentioned goals. [Means for solving the problem]

[0007] To achieve the above object, the present invention provides the following hybrid battery charging method and battery energy station. The hybrid battery charging method according to the present invention is applicable to an electronic device for storing and charging multiple batteries. First, the amount of electricity corresponding to each battery is obtained. Next, the multiple batteries are divided into a first group and a second group based on the amount of electricity of each battery, with each battery in the first group having an amount of electricity equal to or less than a predetermined amount of electricity and each battery in the second group having an amount of electricity higher than the predetermined amount of electricity. Then, a first energy allocation operation is performed for each battery in the first group, in which the first energy allocation operation allocates a charging current to each battery in the first group in order from the battery with the highest amount of electricity to the battery with the lowest amount of electricity, with the allocated charging current corresponding to the maximum current that the battery's charging module can receive. Finally, a second energy allocation operation is performed for each battery in the second group, in which the second energy allocation operation calculates the remaining current by subtracting the charging current allocated in the first energy allocation operation from the total current and allocates the remaining current evenly to each battery in the second group. Then, each battery is charged based on the allocated charging current corresponding to each battery. The battery energy station according to the present invention includes an energy module having a total current, a battery storage system storing a plurality of batteries, and a processing unit. The processing unit is electrically connected to the energy module and the battery storage system, and obtains an electric charge corresponding to each battery, and divides the plurality of batteries into a first group and a second group based on the electric charge of each battery, where each battery in the first group has an electric charge equal to or less than a predetermined electric charge, and each battery in the second group has an electric charge higher than the predetermined electric charge. The processing unit performs a first energy allocation operation for each battery in the first group, in which the first energy allocation operation allocates a charging current to each battery in the first group in order from the battery with the highest electric charge to the battery with the lowest electric charge, the allocated charging current corresponding to the maximum current that the battery's charging module can receive, and performs a second energy allocation operation for each battery in the second group, in which the second energy allocation operation calculates a remaining current by subtracting the charging current allocated in the first energy allocation operation from the total current, and allocates the remaining current evenly to each battery in the second group. The processing unit can charge each battery based on the allocated charging current corresponding to each battery. In some embodiments, before performing the first energy allocation operation and the second energy allocation operation, a specific battery is selected from the plurality of batteries, and the specific battery is used to supply reverse power to the electronic device under a specific condition. Then, a specific energy allocation operation is performed on the specific battery, in which the specific energy allocation operation allocates a predetermined charging current to the specific battery and charges the specific battery based on the predetermined charging current. In some embodiments, the electronic device determines whether it receives an input corresponding to an external power source, and if the electronic device does not receive an input corresponding to an external power source, determines that a specific condition exists, and uses a specific battery to provide power to the electronic device. In some embodiments, after performing the first energy allocation operation, a remaining current is obtained by subtracting the charging current allocated in the first energy allocation operation and a predetermined charging current from the total current, and it is determined whether the obtained remaining current is higher than a preset current. If the obtained remaining current is higher than the preset current, a second energy allocation operation is performed. In some embodiments, a specific signal related to a target battery in the first group is received, and an electrical quantity corresponding to each battery is again obtained according to the specific signal, and the plurality of batteries are divided into a first group and a second group based on the electrical quantity of each battery, and the first energy allocation operation and the second energy allocation operation are again performed. In some embodiments, a particular signal is used to indicate that the target battery is fully charged or that the charging needs associated with the target battery have changed. The above-described method according to the present invention may be implemented as a set of program codes, which, when executed by a machine, turns the machine into an apparatus for performing the method according to the present invention. Other features and advantages of the present invention will become apparent from the following detailed description of the embodiments, which proceeds with reference to the accompanying drawings. [Effects of the Invention]

[0008] The hybrid battery charging method and battery energy station of the present invention can manage the battery charging schedule by adopting a hybrid system based on the battery status under the assumption of a specific charging current, thereby avoiding an increase in the burden on the power grid even during peak electricity usage, and ultimately meeting the needs of battery charging at the battery energy station and battery acquisition by users.

[0010] Hereinafter, the configuration of a battery energy station according to the present invention will be described with reference to the drawings.

[0011] The configuration of a battery energy station according to an embodiment of the present invention will be described with reference to Fig. 1. Fig. 1 is a schematic diagram showing the configuration of a battery energy station 100 according to an embodiment of the present invention.

[0012] A battery energy station 100 according to an embodiment of the present invention is applied to electronic equipment. As shown in FIG. 1, the battery energy station 100 according to the embodiment includes a battery storage system 110, an energy module 120, a network connection unit 130, and a processing unit 140.

[0013] The battery storage system 110, as shown in FIG. 1, is configured to store multiple batteries 112 and have specific structures (not shown) that allow the batteries 112 to be selectively locked or released.

[0014] The battery energy station 100 of this embodiment is for providing batteries to at least one electrical appliance (for example, an electric car or an electric motorcycle).

[0015] The energy module 120 can be electrically connected to the power grid to obtain the total current to provide power to the battery energy station 100 and charge the battery 112 based on signals from the processing unit 140. Note that "electrically connected" in this specification includes wired and wireless connections.

[0016] Additionally, the battery storage system 110 may include a charging module corresponding to each battery 112, and each charging module may have an upper current limit, a lower current limit, or both, to charge the corresponding battery 112.

[0017] Additionally, in some embodiments, the energy module 120 can automatically detect the total current provided by the power grid to the battery energy station 100 and notify the processing unit 140 of information corresponding to the total current.

[0018] The network connection unit 130 can be connected to a network, and thus the battery energy station 100 of this embodiment has the function of connecting to a network. In some embodiments, the network can be a wired network, a telecommunications network, or a wireless network (e.g., Wi-Fi, etc.).

[0019] The processing unit 140 is configured to control the operation of all hardware and software in the battery energy station 100 of this embodiment so as to be able to execute the hybrid battery charging method of the present invention, which will be described later.

[0020] The configuration of a battery energy station according to another embodiment of the present invention will be described with reference to Fig. 2. Here, Fig. 2 is a schematic diagram showing the configuration of a battery energy station according to another embodiment of the present invention.

[0021] Another embodiment of the battery energy station 100 of the present invention is similar to the above-mentioned one, and is applied to electronic equipment, and has multiple batteries, and is intended to provide the batteries to at least one electrical equipment (e.g., an electric vehicle or an electric motorcycle). The battery energy station 100 according to the other embodiment of the present invention includes the same components as the battery energy station 100 shown in FIG. 1, and will not be described further here.

[0022] The battery energy station 100 can be communicatively connected to a remote server 200 via a network 300 using a network connection unit 130, as shown in Figure 2. Here, the network 300 can be a wired network, a telecommunications network, or a wireless network (e.g., Wi-Fi, etc.).

[0023] It should be noted that in some embodiments, the remote server 200 can simultaneously manage battery energy stations at the same location or battery energy stations at different locations.

[0024] As described above, the energy module 120 of the battery energy station 100 can automatically detect the total current provided by the power grid to the battery energy station 100 and notify the processing unit 140 of information corresponding to the total current.

[0025] In some embodiments, the remote server 200 may also communicate information corresponding to the total current to the battery energy station 100 via the network 300. The battery energy station 100 may perform charging management operations based on the information thus received.

[0026] Hereinafter, a hybrid battery charging method according to the present invention will be described with reference to the drawings.

[0027] A hybrid battery charging method according to an embodiment of the present invention will be described with reference to Fig. 3. Here, Fig. 3 is a flowchart showing a hybrid battery charging method according to an embodiment of the present invention.

[0028] A hybrid battery charging method according to an embodiment of the present invention is applied to an electronic device for storing and charging multiple batteries, which is a battery energy station 100 as shown in FIG.

[0029] As shown in FIG. 3, the hybrid battery charging method according to one embodiment of the present invention includes the following steps S310 to S350.

[0030] First, in step S310, the amount of electricity corresponding to each battery 112 is obtained. It should be noted that in some embodiments, the charging module in the battery energy station 100 sends a signal to the battery 112 electrically connected thereto to sense its electrical charge, thereby obtaining the electrical charge corresponding to the battery 112.

[0031] Next, in step S320, the plurality of batteries 112 are divided into a first group and a second group based on the amount of electricity in each battery 112. Wherein, each battery 112 in the first group has an electric quantity equal to or less than a predetermined electric quantity, and each battery 112 in the second group has an electric quantity higher than the predetermined electric quantity. In some embodiments, the predetermined electric quantity may be set to a predetermined electric quantity level (e.g., 90% of the total current of the batteries 112). It should be noted that the above-mentioned predetermined electric quantity or predetermined electric quantity level is merely an example of the present application and is not limited in the present invention.

[0032] In step S330, a first energy allocation task is performed for each battery 112 in the first group. In the first energy allocation operation, the charging current is allocated to each battery 112 in the first group in order from the battery 112 with the highest amount of electricity to the battery 112 with the lowest amount of electricity. In some embodiments, the allocated charging current corresponds to the maximum current that the charging module of the battery 112 can receive, for example, 17 A (amperes). As described above, each battery 112 may include a corresponding charging module, and the charging module may have an upper current limit, a lower current limit, or both, to charge the corresponding battery 112. Please note that the maximum and minimum current of each charging module may vary depending on the manufacturer and design specifications.

[0033] In step S340, a second energy allocation operation is performed for each battery 112 in the second group. Among them, the second energy allocation operation obtains the remaining current by subtracting the charging current allocated in the first energy allocation operation from the total current of the electronic equipment, and allocates the obtained remaining current evenly to each battery 112 in the second group.

[0034] Then, in step S350, each battery 112 is charged based on the allocated charging current corresponding to each battery 112.

[0035] A hybrid battery charging method according to another embodiment of the present invention will be described with reference to Fig. 4. Here, Fig. 4 is a flowchart showing a hybrid battery charging method according to another embodiment of the present invention.

[0036] Another embodiment of the hybrid battery charging method according to the present invention is applied to an electronic device for storing and charging multiple batteries 112. The electronic device is a battery energy station 100 as shown in Figure 1. In this embodiment, the charging schedule can be adjusted based on receiving a specific signal.

[0037] As shown in FIG. 4, a hybrid battery charging method according to another embodiment of the present invention includes the following steps S410 to S450.

[0038] First, in step S410, it is determined whether a specific signal related to the target battery in the corresponding battery 112 has been received. It should be noted that in some embodiments, the particular signal may be a signal used to indicate that the target battery is in a fully charged state, and in some embodiments, the particular signal may be a signal used to indicate that the charging needs corresponding to the target battery have changed.

[0039] If the specific signal has not been received ("NO" in step S410), the flow proceeds to step S450. In step S450, each battery 112 is charged based on the originally allocated charging current corresponding to each battery 112.

[0040] If a specific signal corresponding to the target battery is received (YES in step S410), the flow proceeds to step S420. In step S420, the amount of electricity corresponding to each battery 112 is acquired again.

[0041] In step S430, the plurality of batteries 112 are divided into a first group and a second group based on the amount of electricity in each battery 112. Similarly, each battery 112 in the first group has an electrical quantity equal to or less than a predetermined electrical quantity, and each battery 112 in the second group has an electrical quantity higher than the predetermined electrical quantity.

[0042] Then, in step S440, the first energy allocation operation described above is performed again for each battery 112 in the first group, and the second energy allocation operation is performed for each battery 112 in the second group. Similarly, in the first energy allocation operation, charging current is allocated to each battery 112 in the first group in order from the battery 112 with the highest amount of electricity to the battery 112 with the lowest amount of electricity. In the second energy allocation operation, the remaining current is obtained by subtracting the charging current allocated in the first energy allocation operation from the total current of the electronic equipment, and the remaining current is allocated evenly to each battery 112 in the second group.

[0043] Then, in step S450, each battery 112 is charged based on the allocated charging current corresponding to each battery 112.

[0044] A hybrid battery charging method according to another embodiment of the present invention will be described with reference to Fig. 5. Here, Fig. 5 is a flowchart showing a hybrid battery charging method according to another embodiment of the present invention.

[0045] Another embodiment of the hybrid battery charging method according to the present invention is applied to an electronic device for storing and charging multiple batteries 112. The electronic device is a battery energy station 100 as shown in FIG.

[0046] As shown in FIG. 5, a hybrid battery charging method according to another embodiment of the present invention includes the following steps S510 to S560.

[0047] First, in step S510, the amount of electricity corresponding to each battery 112 is obtained. Similarly, in some embodiments, the charging module in the battery energy station 100 sends a signal to the battery 112 electrically connected thereto to sense its electrical charge, thereby obtaining the electrical charge corresponding to the battery.

[0048] Next, in step S520, a specific battery 112 is selected from the plurality of batteries 112, and a specific energy allocation task is performed on the specific battery 112. Among them, a particular energy allocation task allocates a predetermined charging current (eg, 1 A) to a particular battery 112 . It should be noted that certain batteries 112 are used to provide reverse power to electronic equipment under certain conditions. It should be noted that in some embodiments, the battery with the least amount of electricity among the plurality of batteries 112 may be selected as the specific battery 112. In some embodiments, the battery 112 with the least amount of electricity among the batteries 112 that is higher than the first battery level may be selected as the specific battery 112. It should be noted that the above-mentioned method of selecting the particular battery 112 and the prescribed charging current are merely examples of the present invention and are not limiting of the present invention.

[0049] A hybrid battery charging method according to another embodiment of the present invention will be described with reference to Fig. 6. Here, Fig. 6 is a flowchart showing a hybrid battery charging method according to another embodiment of the present invention. In this embodiment, the specific condition may be set as the electronic device not receiving an external power supply input.

[0050] First, in step S610, it is determined whether the electronic device receives an input corresponding to an external power source. If the electronic device receives an input corresponding to an external power source ("NO" in step S610), the flow repeats step S610, that is, continues to make the determination in step S610.

[0051] If the electronic device does not receive an input corresponding to an external power source (YES in step S610), the flow proceeds to step S620. In step S620, it is determined that a specific condition is met.

[0052] In step S630, a particular battery 112 is used to provide power to the electronic device.

[0053] Here, we return to the explanation of FIG. Then, in step S530, the plurality of batteries 112 are divided into a first group and a second group based on the amount of electricity in each battery 112. Wherein, each battery 112 in the first group has an electric quantity equal to or less than a predetermined electric quantity, and each battery 112 in the second group has an electric quantity higher than the predetermined electric quantity. Similarly, in some embodiments, the predetermined electric quantity may be set to a predetermined electric quantity level (e.g., 90% of the total current of the batteries 112). Please note that the above-mentioned predetermined electric quantity or the above-mentioned predetermined electric quantity level is merely an example of the present application and is not limited in the present invention.

[0054] In step S540, a first energy allocation task is performed for each battery 112 in the first group. The first energy allocation operation allocates charging current to each battery 112 in the first group in order from the battery 112 with the highest amount of electricity to the battery 112 with the lowest amount of electricity. In some embodiments, the allocated charging current is the maximum current that the charging module corresponding to the battery 112 can receive. Similarly, the maximum and minimum current for each charging module may vary depending on the manufacturer and design specifications.

[0055] In step S550, a second energy allocation operation is performed for each battery 112 in the second group. Among them, the second energy allocation operation obtains the remaining current by subtracting the charging current allocated in the first energy allocation operation from the total current of the electronic equipment, and allocates the obtained remaining current evenly to each battery 112 in the second group.

[0056] Then, in step S560, each battery 112 is charged based on the allocated charging current corresponding to each battery 112.

[0057] A hybrid battery charging method according to another embodiment of the present invention will be described with reference to Fig. 7. Here, Fig. 7 is a flowchart showing a hybrid battery charging method according to another embodiment of the present invention.

[0058] Another embodiment of the hybrid battery charging method according to the present invention is applied to an electronic device for storing and charging multiple batteries 112. The electronic device is a battery energy station as shown in FIG.

[0059] As shown in FIG. 7, a hybrid battery charging method according to another embodiment of the present invention includes the following steps S710 to S770.

[0060] First, in step S710, the amount of electricity corresponding to each battery 112 is obtained. Similarly, in some embodiments, the charging module in the battery energy station 100 sends a signal to the battery 112 electrically connected thereto to sense its electrical charge, thereby obtaining the electrical charge corresponding to the battery 112.

[0061] Next, in step S720, a specific battery 112 is selected from the plurality of batteries 112, and a specific energy allocation task is performed on the specific battery 112. Among them, a specific energy allocation task is to allocate a predetermined charging current (for example, 1 A) to a specific battery. It should be noted that certain batteries can be used to provide reverse power to electronic equipment under certain conditions. Similarly, in some embodiments, the battery with the least amount of electricity among the plurality of batteries 112 may be selected as the specific battery 112. In some embodiments, the battery with the least amount of electricity among the batteries 112 that is higher than the first battery level may be selected as the specific battery 112. It should be noted that the above-mentioned method of selecting the particular battery 112 and the prescribed charging current are merely examples of the present invention and are not limiting of the present invention.

[0062] Then, in step S730, the plurality of batteries 112 are divided into a first group and a second group based on the amount of electricity in each battery 112. Wherein, each battery 112 in the first group has an electric quantity equal to or less than a predetermined electric quantity, and each battery 112 in the second group has an electric quantity higher than the predetermined electric quantity. Similarly, in some embodiments, the predetermined electric quantity may be set to a predetermined electric quantity level (e.g., 90% of the total current of the batteries 112). Please note that the above-mentioned predetermined electric quantity or the above-mentioned predetermined electric quantity level is merely an example of the present application and is not limited in the present invention.

[0063] In step S740, a first energy allocation operation is performed for each battery 112 in the first group. Among these, the first energy allocation task allocates charging current to each battery 112 in the first group in order from the battery 112 with the highest amount of electricity to the battery 112 with the lowest amount of electricity. As mentioned above, the maximum and minimum currents for each charging module may vary depending on the manufacturer and design specifications. Note that the allocated charging current may be the maximum current required or available for the battery 112 or charging module. If the remaining current is lower than the maximum current required or available for the subsequent battery 112 or charging module, the remaining current is used to charge the subsequent battery 112. For example, if the total current is 40 A and the current required or the maximum current that each battery 112 or charging module can receive is 17 A, 17 A of charging current is allocated to battery A with the highest amount of electricity in the first group, 17 A of charging current is allocated to battery B with the second highest amount of electricity in the first group, and the remaining 6 A of charging current is allocated to battery C with the third highest amount of electricity in the first group. If the first group also includes battery D with the fourth highest amount of electricity, no charging current is allocated to battery D in the first energy allocation operation.

[0064] Then, in step S750, after the specific energy allocation operation and the first energy allocation operation are performed, the remaining current is obtained by subtracting the predetermined charging current allocated in the specific energy allocation operation and the charging current allocated in the first energy allocation operation from the total current, and it is determined whether the obtained remaining current is higher than the preset current. Note that the preset current can be adjusted according to different needs and applications. If the remaining current is higher than the preset current (YES in step S750), the flow proceeds to step S760.

[0065] In step S760, a second energy allocation operation is performed for each battery 112 in the second group. Wherein, the second energy allocation task allocates the remaining current in the electronic equipment evenly to each battery 112 in the second group.

[0066] Then, in step S770, each battery 112 is charged based on the allocated charging current corresponding to each battery 112. If the remaining current is less than or equal to the preset current ("NO" in step S750), the flow proceeds to step S770; in other words, the second energy allocation task is not performed.

[0067] As described above, the electronic device can provide the battery 112 in response to a user-submitted need. In some embodiments, the battery energy station 100 or the electronic device can receive the need for the battery 112. Note that in some embodiments, a user can trigger a need for a battery 112 by placing a used battery 112 into the battery energy station 100. In some embodiments, a user can also submit a need for the battery 112 via a user interface at the battery energy station 100.

[0068] To meet the user's need for batteries 112, the battery energy station 100 or the electronic device can select at least one battery 112 from the plurality of batteries 112 whose corresponding electrical quantity is higher than a specific electrical quantity ratio as a candidate battery, and the candidate battery can be provided to be removed from the battery energy station 100. It should be noted that the specific electrical quantity ratio can be set according to different applications and needs.

[0069] As described above, the hybrid battery charging method and battery energy station according to the present invention can manage a hybrid battery charging schedule based on the state of the battery 112, assuming a specific charging current. This can avoid increasing the burden on the power grid even during peak electricity usage, and can also meet the needs of charging the battery 112 at the battery energy station 100 and obtaining the battery 112 by the user.

[0070] Furthermore, the method, specific embodiment, or part thereof of the present invention may be embodied as a set of program code. The set of program code may be stored on a physical storage medium, such as a floppy disk, a compact disk, a hard disk, or any machine-readable (e.g., computer-readable) storage medium, or may be executed as a computer program, regardless of its physical form. Here, when the program code is executed by a machine (e.g., a computer), the machine becomes an apparatus for performing the method of the present invention. Furthermore, the program code may be transmitted via a transmission medium, such as one or more wires, cables, optical fibers, or any transmission means. And when the program code is read, loaded, and executed by a machine (e.g., a computer), the machine becomes an apparatus for performing the method of the present invention. When the method is executed by a general-purpose processor, the program code can cause the processor to operate as a specific device with functionality similar to an application-specific integrated circuit (ASIC).

[0071] Although numerous specific details are set forth above to provide a thorough understanding of the present invention, it will be apparent to one skilled in the art that one or more other embodiments may be practiced without these specific details.

[0072] While the preferred embodiments and variations of the present invention have been described above, the present invention is not limited to these and encompasses all modifications and equivalents as various configurations falling within the spirit and scope of the broadest interpretation.
