Description

[Technical Field]

[0001] This invention relates to a battery charging management method and a battery power station thereof, and more particularly to a battery charging management method and a battery power station based on a state-of-charge (SOC) setting. [Previous Technology]

[0002] In recent years, with the rise of environmental awareness and the advancement of electric vehicle technology, developing electric vehicles that use electricity as their power source to replace traditional vehicles powered by fossil fuels has gradually become an important goal in the automotive field, thus making electric vehicles increasingly popular. In order to improve the range of electric vehicles and the willingness to use them, many countries and cities have begun to plan the installation of charging stations and battery energy stations in public places to provide charging or battery swapping services for electric vehicles and / or electric motorcycles, making the use of electric vehicles more convenient.

[0003] Generally speaking, rechargeable batteries are one of the most important costs for battery manufacturers, and they have a limited lifespan. For some electric vehicles, such as electric motorcycles, when the battery power is insufficient, the individual battery capacity varies too much, and / or the individual battery lifespan varies too much, if the user tries to start the electric vehicle with these battery combinations, it will affect the function or lifespan of the vehicle or the battery itself.

[0004] On the other hand, the high cost of batteries is also one of the main reasons for the high service fees of electric motorcycles. If different charging modes can be planned according to user needs, or even different suppliers can be introduced into the electric vehicle ecosystem, it may be possible to moderately reduce the overall service fees of electric motorcycles and further increase users' willingness to adopt electric motorcycles. [Summary of the Invention]

[0005] In view of this, the present invention provides a battery charging management method based on state of charge setting and a battery power station thereof.

[0006] One embodiment of the present invention provides a battery charging management method based on state of charge (SOC) setting, applicable to a battery power station for storing and charging multiple batteries. First, first battery SOC ratio data corresponding to the battery power station is provided, wherein the first battery SOC ratio data records the proportion of a first battery quantity in the battery power station that is set to a first target SOC value. Next, a specific battery is obtained using the battery power station. Then, it is determined whether the number of batteries in the battery power station that are set to the first target SOC value has reached the first battery quantity ratio. When the number of batteries in the battery power station that are set to the first target SOC value has not reached the first battery quantity ratio, a charging target value for the specific battery is set as the first target SOC value, and a charging operation is performed on the specific battery according to the first target SOC value until the specific battery reaches the first target SOC value.

[0007] A battery power station according to an embodiment of the present invention includes a storage unit, a battery storage system including a plurality of batteries, an energy module for charging the batteries, and a processing unit. The storage unit includes first battery state of charge ratio data, wherein the first battery state of charge ratio data records the proportion of a first battery quantity in the battery power station that is set to a first target state of charge value. The processing unit is coupled to the battery storage system and the energy module to receive a specific battery and determine whether the number of batteries in the battery power station that are set to the first target state of charge value has reached the first battery quantity ratio. When the number of batteries in the battery power station that are set to the first target state of charge value has not reached the first battery quantity ratio, the processing unit sets a charging target value for the specific battery as the first target state of charge value, and performs a charging operation on the specific battery according to the first target state of charge value until the specific battery has the first target state of charge value.

[0008] In some embodiments, when the number of batteries in the battery power station that are set to the first target state of charge value has reached the first battery quantity ratio, the charging target value of the specific battery is set to a preset target state of charge value, and the charging operation is performed on the specific battery according to the preset target state of charge value until the specific battery has the preset target state of charge value.

[0009] In some embodiments, the battery state-of-charge (SOC) ratio data further records the proportion of a second battery in the battery power station that is set to a second target SOC value. When the number of batteries in the battery power station that are set to the first target SOC value has reached the first battery proportion, it is determined whether the number of batteries in the battery power station that are set to the second target SOC value has reached the second battery proportion. When the number of batteries in the battery power station that are set to the second target SOC value has not reached the second battery proportion, the charging target value of the specific battery is set to the second target SOC value, and the charging operation is performed on the specific battery according to the second target SOC value until the specific battery has the second target SOC value.

[0010] In some embodiments, when the number of batteries in the battery power station that are set to the second target state of charge value has reached the proportion of the second battery number, the charging target value of the specific battery is set to a preset target state of charge value, and the charging operation is performed on the specific battery according to the preset target state of charge value until the specific battery has the preset target state of charge value.

[0011] In some embodiments, it is determined whether the battery power station has a specific target state of charge value. When the battery power station does not have the specific target state of charge value, and the number of batteries in the battery power station that are set to the first target state of charge value has reached the first battery quantity ratio, the charging target value of the specific battery is set to the preset target state of charge value.

[0012] In some embodiments, when the battery power station has the specific target state of charge value, and the number of batteries in the battery power station that are set to the first target state of charge value has reached the first battery quantity ratio, the charging target value of the specific battery is set as the specific target state of charge value.

[0013] In some embodiments, the battery power station receives the specific target state of charge value from a remote server via a network route.

[0014] In some embodiments, second battery state-of-charge (SOC) ratio data corresponding to one of the battery power stations is provided, wherein the first battery SOC ratio data corresponds to a peak period, and the second battery SOC ratio data corresponds to an off-peak period. A current time is obtained using the battery power station, and it is determined whether the current time is the peak period or the off-peak period. Based on the determination result, the first battery SOC ratio data or the second battery SOC ratio data is selected for subsequent setting of the charging target value for the specific battery.

[0015] The method described above can exist through program code. When the program code is loaded and executed by a machine, the machine becomes an apparatus for implementing the present invention.

Implementation Method

[0017] Figure 1 shows a battery power station according to an embodiment of the present invention. The battery power station 100 according to an embodiment of the present invention can be an electronic device. As shown, the battery power station 100 includes at least a battery storage system 110, a storage unit 120, an energy module 130, a network connection unit 140, and a processing unit 150. The battery storage system 110 has a specific mechanism (not shown) that can store a plurality of batteries 112 and selectively lock or release these batteries. The battery power station 100 can provide batteries to at least one electrical device, such as an electric motorcycle or an electric vehicle. The storage unit 120 can include at least one battery state-of-charge (SOC) ratio data. The SOC ratio data can record the proportion of batteries in the battery power station 100 that are set to at least one target SOC value. In other words, the SOC ratio data can define the proportion of batteries in the battery power station that have different SOC values ​​after charging. In one example, the battery state-of-charge (SOC) ratio data can define the proportion of batteries with a SOC value of 70 in this battery power station 100 as 40%, and the proportion of batteries with a SOC value of 80 as 60%. In another example, the battery SOC ratio data can define the proportion of batteries with a SOC value of 70 in this battery power station 100 as 30%, the proportion of batteries with a SOC value of 85 as 30%, and the proportion of batteries with a SOC value of 80 as 40%. In some embodiments, the storage unit 120 may include first battery SOC ratio data for a corresponding peak period and second battery SOC ratio data for a corresponding off-peak period. The contents defined in the first battery SOC ratio data and the second battery SOC ratio data may be different. The usage of the battery SOC ratio data will be described later.

[0018] The energy module 130 can be electrically coupled to a power grid (not shown) to obtain a total current to supply power to the battery power station and charge the battery 112 according to the signal from the processing unit 150. It must be noted that the battery storage system 110 may include a charging module for each battery 112, and the charging module has an upper current limit and / or a lower current limit to charge the corresponding battery. It is worth noting that in some embodiments, the energy module 130 can actively detect the total current supplied to the battery power station 100 by the power grid and notify the processing unit 150 of the corresponding total current information. The network connection unit 140 can be connected to a network, thereby enabling the battery power station 100 to have network connectivity. In some embodiments, the network can be a wired network, a telecommunications network, or a wireless network, such as a Wi-Fi network. The processing unit 150 can control the operation of all hardware and software in the battery power station 100 and execute the battery charging management method based on the state of charge setting of this case, the details of which will be explained later.

[0019] Figure 2 shows a battery power station connected to a remote server via a network according to another embodiment of the present invention. Similarly, the battery power station 100 according to an embodiment of the present invention can be an electronic device having a plurality of batteries that can provide power to at least one power-consuming device, such as an electric motorcycle or an electric vehicle. The battery power station 100 can have components similar to those in Figure 1, which will not be described again here. The battery power station 100 can be connected to a remote server 200 via a network 300, such as a wired network, a telecommunications network, or a wireless network, such as a Wi-Fi network, using a network connection unit 140. It should be noted that in some embodiments, the remote server 200 can simultaneously manage other battery power stations located in the same location or in different locations. As mentioned above, the energy module 120 of the battery power station 100 can actively detect the total current supplied to the battery power station 100 by the power grid and notify the processing unit 150 of the corresponding total current information. In some embodiments, the remote server 200 may also notify the battery power station 100 of the corresponding total current information via the network 300. In some embodiments, the remote server 200 may also transmit relevant information for different time periods, such as peak hours and off-peak hours, to the battery power station 100 via the network 300. The battery power station 100 can perform charging management operations based on the received information.

[0020] Figure 3 shows a battery charging management method based on state of charge setting according to an embodiment of the present invention. The battery charging management method based on state of charge setting according to an embodiment of the present invention is applicable to an electronic device for storing and charging multiple batteries, such as the battery power station in Figure 1.

[0021] First, as in step S310, battery state-of-charge (SOC) ratio data for one of the corresponding battery power stations is provided, wherein the SOC ratio data records at least the proportion of first batteries in the battery power station that are set to a first target SOC value. Next, as in step S320, the battery power station acquires a specific battery, and as in step S330, it determines whether the number of batteries in the battery power station set to the first target SOC value has reached the first battery quantity ratio. When the number of batteries in the battery power station set to the first target SOC value has reached the first battery quantity ratio (Yes in step S340), the process ends. When the number of batteries in the battery power station that are set to the first target state of charge value does not reach the first battery quantity ratio (No in step S340), as in step S350, the charging target value of one of the specific batteries is set as the first target state of charge value, and as in step S360, a charging operation is performed on the specific battery according to the first target state of charge value until the specific battery has the first target state of charge value.

[0022] Figure 4 shows a battery charging management method based on state of charge setting according to another embodiment of the present invention. The battery charging management method based on state of charge setting according to the embodiment of the present invention is applicable to an electronic device for storing and charging multiple batteries, such as the battery power station in Figure 1.

[0023] First, as in step S410, battery state-of-charge (SOC) ratio data for one of the corresponding battery power stations is provided, wherein the SOC ratio data records at least the proportion of a first battery quantity in the battery power station that is set to a first target SOC value. Next, as in step S420, the battery power station acquires a specific battery, and as in step S430, it is determined whether the number of batteries in the battery power station that are set to the first target SOC value has reached the first battery quantity ratio. When the number of batteries in the battery power station that are set to the first target SOC value has not reached the first battery quantity ratio (No in step S440), as in step S450, a charging target value for the specific battery is set as the first target SOC value, and as in step S460, a charging operation is performed on the specific battery according to the first target SOC value until the specific battery has the first target SOC value. When the number of batteries in the battery power station that are set to the first target state of charge (SOC) has reached the first battery quantity ratio (yes in step S440), as in step S470, the charging target value of the specific battery is set to a preset target SOC, and as in step S480, the charging operation is performed on the specific battery according to the preset target SOC until the specific battery has the preset target SOC. It is worth noting that in some embodiments, each battery power station may have its own corresponding preset target SOC.

[0024] Figure 5 shows a battery charging management method based on state of charge setting according to another embodiment of the present invention. The battery charging management method based on state of charge setting according to an embodiment of the present invention is applicable to an electronic device for storing and charging multiple batteries, such as the battery power station in Figure 1. It should be noted that in some embodiments, a remote server can instruct a specific battery power station as needed to maintain the internal batteries at a specific state of charge.

[0025] When the number of batteries in the battery power station set to the first target state of charge value does not reach the first battery quantity ratio (No in step S440), steps S450 and S460 are executed. When the number of batteries in the battery power station set to the first target state of charge value has reached the first battery quantity ratio (Yes in step S440), as in step S442, it is determined whether the battery power station has a specific target state of charge value. Note that the battery power station can receive the specific target state of charge value from a remote server via a network router. When the battery power station does not have the specific target state of charge value (No in step S442), steps S470 and S480 are executed. When the battery power station has the specific target state of charge value (as in step S442), as in step S492, the charging target value of the specific battery is set to the specific target state of charge value, and as in step S494, the charging operation is performed on the specific battery according to the specific target state of charge value until the specific battery has the specific target state of charge value.

[0026] It must be noted that the embodiments in Figures 3, 4, and 5 are illustrated using only a single target state of charge (SOC) value and its battery quantity ratio. However, in some embodiments, the battery SOC ratio data can define multiple target SOC values ​​and their battery quantity ratios. In some embodiments, when the number of batteries in the battery power station set to the first target SOC value has reached the first battery quantity ratio, it can be determined whether the number of batteries in the battery power station set to the second target SOC value has reached the second battery quantity ratio. When the number of batteries in the battery power station set to the second target SOC value has not reached the second battery quantity ratio, the charging target value of the specific battery is set as the second target SOC value, and the charging operation is performed on the specific battery according to the second target SOC value until the specific battery has the second target SOC value. When the number of batteries in the battery power station that are set to the second target state of charge value has reached the proportion of the second battery number, the charging target value of the specific battery is set to a preset target state of charge value, and the charging operation is performed on the specific battery according to the preset target state of charge value until the specific battery has the preset target state of charge value.

[0027] Figure 6 shows a battery charging management method based on state of charge setting according to another embodiment of the present invention. The battery charging management method based on state of charge setting according to an embodiment of the present invention is applicable to an electronic device for storing and charging multiple batteries, such as the battery power station in Figure 1.

[0028] First, as in step S610, the battery power station obtains a current time, and as in step S620, determines whether the current time is a peak period or an off-peak period. It should be noted that the peak and off-peak periods can be predefined in the battery power station or received from a remote server via a network router. It should also be noted that the storage unit 120 may include first battery state-of-charge (SOC) ratio data for one of the corresponding peak periods and second battery SOC ratio data for one of the corresponding off-peak periods. The contents defined in the first and second SOC ratio data can be different. Based on the determination result, either the first or second SOC ratio data is selected for subsequent setting of the charging target value for the specific battery. When the current time is a peak period, as in step S630, the battery power station obtains the first battery SOC ratio data for the corresponding peak period, and as in step S640, performs the battery charging target value setting based on the first battery SOC ratio data. When the current time is an off-peak period, as in step S650, the battery power station obtains the second battery state of charge ratio data for the corresponding off-peak period, and as in step S660, sets the battery charging target value based on the second battery state of charge ratio data.

[0029] Therefore, through the battery charging management method based on the state of charge setting and its battery power station in this case, the battery can be set and charged according to the ratio of the number of batteries with different target state of charge values, thereby extending the battery life and meeting the user's battery needs by adjusting the charging parameters.
