Description

Technical Field

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

[0002] In recent years, with rising environmental awareness and advancements in electric vehicle technology, developing electric vehicles to replace traditional vehicles powered by fossil fuels has gradually become a key objective in the automotive industry, leading to the increasing popularity of electric vehicles. To improve the range and user willingness of electric vehicles, many countries and cities have begun planning to install charging stations and battery power 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 a significant cost 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 capacities vary greatly, and / or the individual battery lifespans vary greatly, using these battery combinations to start the electric vehicle can negatively impact the vehicle's functionality or the battery's lifespan.

[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 could be planned according to user needs, or even if different suppliers were introduced into the electric vehicle ecosystem, it might be possible to moderately reduce the overall service fees of electric motorcycles and further increase users' willingness to adopt them. 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] This invention discloses 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, a 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 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 set to the first target SOC value has reached the first battery quantity ratio. If the number of batteries in the battery power station 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] An embodiment of the present invention provides a battery power station comprising 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 (SOC) ratio data, wherein the first SOC ratio data records the proportion of a first battery quantity in the battery power station set to a first target SOC 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 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 not reached the first battery quantity ratio, the processing unit sets a charging target value for the specific battery to the first target SOC value and performs a charging operation on the specific battery according to the first target SOC value until the specific battery reaches the first target SOC 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 a second proportion of the number of batteries in the battery power station that are 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 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 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 proportion, the charging target value for 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 reaches 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 (SOC). When the battery power station does not have the specific target SOC, and the number of batteries in the battery power station that are set to the first target SOC has reached the first battery quantity ratio, the charging target value of the specific battery is set to the preset target SOC.

[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, a second battery state-of-charge (SOC) ratio corresponding to the battery power station is provided, wherein the first battery SOC ratio corresponds to a peak period, and the second battery SOC ratio corresponds to an off-peak period. The battery power station obtains a current time and determines whether the current time is during the peak or off-peak period. Based on the determination result, either the first or second battery SOC ratio is selected for subsequent setting of the charging target value for the specific battery.

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

[0036] Figure 1 This invention illustrates 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) for storing multiple batteries 112 and selectively locking or releasing these batteries. The battery power station 100 can provide batteries to at least one electrical device, such as an electric motorcycle or 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 with 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 a first battery SOC ratio data for a corresponding peak period and a 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.

[0037] 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 battery 112 according to the signal from processing unit 150. It should 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, energy module 130 can actively detect the total current supplied to battery power station 100 by the power grid and notify processing unit 150 of the corresponding total current information. Network connection unit 140 can be connected to a network, thereby enabling 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. Processing unit 150 can control the operation of all hardware and software in battery power station 100 and execute the battery charging management method based on state of charge setting of this invention, the details of which will be described later.

[0038] Figure 2 This illustrates 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 multiple batteries that can supply power to at least one power-consuming device, such as an electric motorcycle or electric vehicle. The battery power station 100 can have, for example, […]. Figure 1 Similar components will not be described in detail here. The battery power station 100 can connect to a remote server 200 via a network 300, such as a wired network, telecommunications network, or wireless network, such as Wi-Fi, using the 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 or different locations. As mentioned earlier, 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 can also notify the battery power station 100 of the corresponding total current information via the network 300. In some embodiments, the remote server 200 can 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.

[0039] Figure 3 This invention discloses a battery charging management method based on state of charge (SBC) settings according to an embodiment of the present invention. The battery charging management method based on SBC settings according to an embodiment of the present invention is applicable to an electronic device for storing and charging multiple batteries, such as… Figure 1 Battery power station.

[0040] First, as in step S310, battery state-of-charge (SOC) ratio data for the corresponding battery power station 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 S320, the battery power station acquires a specific battery, and as in step S330, 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 set to the first target SOC value has not reached the first battery quantity ratio (No in step S340), as in step S350, a charging target value for the specific battery is set as the first target SOC value, and as in step S360, 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.

[0041] Figure 4 This invention discloses 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 this invention is applicable to an electronic device for storing and charging multiple batteries, such as… Figure 1 Battery power station.

[0042] First, as in step S410, battery state-of-charge (SOC) ratio data for the corresponding battery power station 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 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. If the number of batteries in the battery power station 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 reaches the first target SOC value. When the number of batteries in the battery power station set to the first target state of charge (SOC) reaches 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.

[0043] Figure 5 This invention discloses 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 this invention is applicable to an electronic device for storing and charging multiple batteries, such as… Figure 1 The battery power station. It should be noted that in some embodiments, the remote server can instruct a specific battery power station as needed to maintain the internal batteries at a specific state of charge.

[0044] If the number of batteries in the battery power station set to the first target state of charge (SOC) does not reach the first battery quantity ratio (No in step S440), steps S450 and S460 are executed. If the number of batteries in the battery power station set to the first target SOC 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 SOC. Note that the battery power station can receive the specific target SOC from a remote server via a network router. If the battery power station does not have the specific target SOC (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.

[0045] It must be stated that, Figure 3 , Figure 4 and Figure 5 The embodiments are described 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 for 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.

[0046] Figure 6 This invention discloses 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 this invention is applicable to an electronic device for storing and charging multiple batteries, such as… Figure 1 Battery power station.

[0047] 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 a first battery state-of-charge (SOC) ratio for the corresponding peak period and a second SOC ratio for the corresponding off-peak period. The contents defined in the first and second SOC ratios can be different. Based on the determination result, either the first or second SOC ratio 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 SOC ratio for the corresponding peak period, and as in step S640, performs the battery charging target value setting based on the first SOC ratio. 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.

[0048] Therefore, the battery charging management method based on state of charge setting and its battery power station in this case can set the batteries and manage charging 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.

The program code may be contained in physical media, such as floppy disks, optical discs, hard disks, or any other machine-readable (e.g., computer-readable) storage media, or may be a computer program product, not limited to an external form.
