[0026] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.

[0027] The terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish different objects, not to describe a specific order. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion.

[0028] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0029] The embodiments of this application will now be described with reference to the accompanying drawings.

[0030] Please see Figure 1 , Figure 1 This is a schematic diagram of an application scenario for a charging method based on battery thermal energy provided in an embodiment of this application. The application scenario 100 includes a management server 101, an energy storage battery 102, a thermoelectric conversion device 103, and a heat conduction pipe 104.

[0031] The management server 101 is used to acquire various operational information (such as temperature, stored capacity, etc.) of the energy storage battery 102 and the thermoelectric conversion device 103, and to control the energy storage battery 102 and the thermoelectric conversion device 103 based on this information. The thermoelectric conversion device 103 is connected to the energy storage battery 102 via a heat-conducting pipe 104, which can be made of heat-conducting materials such as graphite or copper. The heat-conducting pipe 104 conducts the heat energy generated by the energy storage battery 102 to the thermoelectric conversion device 103. The thermoelectric conversion device 103 converts the heat energy into electrical energy and transmits it to the energy storage battery 102. The example of three energy storage batteries 102 is provided and should not be considered a limitation on the number of energy storage batteries.

[0032] The management server 101 acquires the number of charging cycles of multiple energy storage batteries 102, and identifies the energy storage battery with a rechargeable cycle greater than the predicted cycle as the first target energy storage battery. It acquires the first amount of electricity generated by the thermoelectric conversion device 103 in a first time period, and predicts a second amount of electricity based on the first amount. When the second amount of electricity exceeds a first preset amount, based on the first remaining amount of electricity in the first target energy storage battery, it identifies the first target energy storage battery with a first remaining amount of electricity less than a second preset amount as the second target energy storage battery. During the second time period, the electricity generated by the thermoelectric conversion device 103 is stored in the second target energy storage battery until the second remaining amount of electricity in the second target energy storage battery exceeds the second preset amount.

[0033] It can be seen that by using a thermoelectric converter, the heat generated by the energy storage battery in the energy storage device during use is converted into electrical energy, saving energy waste caused by the heat dissipation process of the energy storage battery; when it is predicted that the thermoelectric converter can provide more electrical energy than a certain amount, the electrical energy generated by the thermoelectric converter is released into the energy storage battery that needs to be charged, avoiding repeated small-scale charging of the energy storage battery, thereby reducing the number of charging cycles of the energy storage battery and improving the service life of the energy storage battery.

[0034] Please see Figure 2 , Figure 2 This application provides a schematic flowchart of a charging method based on battery thermal energy, which can be based on... Figure 1 The application scenarios shown are implemented as follows: Figure 2 As shown, it includes steps S201-S204.

[0035] S201: The server obtains the number of times each energy storage battery can be recharged, and identifies the energy storage battery with more than the predicted number of times it can be recharged as the first target energy storage battery.

[0036] Specifically, the number of rechargeable times here refers to the estimated number of times that the energy storage device can be recharged before entering maintenance mode. The server identifies energy storage batteries with a number of rechargeable times greater than the predicted number of times as the first target energy storage battery. The first target energy storage battery is used to receive electrical energy generated by the thermoelectric conversion device in the future, so that the number of rechargeable times of multiple energy storage batteries remains close.

[0037] In one possible embodiment, the server obtains the number of rechargeable times of multiple energy storage batteries, including: the server obtaining the current available capacity, maximum available capacity, and number of recharges for each of the multiple energy storage batteries; subtracting the current available capacity from the maximum available capacity of each energy storage battery to determine the consumed capacity of each energy storage battery; subtracting the minimum available capacity from the current available capacity of each energy storage battery to determine the consumed capacity of each energy storage battery, where the minimum available capacity is the available capacity of each energy storage battery when it enters a maintenance-ready state; dividing the consumed capacity of each energy storage battery by the quotient of the number of recharges for each energy storage battery to determine the capacity consumed per charge for each energy storage battery; and dividing the consumed capacity of each energy storage battery by the quotient of the capacity consumed per charge for each energy storage battery to determine the number of rechargeable times for each energy storage battery.

[0038] Specifically, the current available capacity refers to the maximum amount of electricity that the energy storage battery can actually store. The maximum available capacity refers to the maximum amount of electricity that the energy storage battery can theoretically store. The number of times the battery has been charged refers to the number of times the energy storage battery has been charged since it was put into use. Based on the current available capacity and the maximum available capacity, the amount of capacity reduction due to use can be determined, and the average loss of current available capacity per charge can be calculated based on the number of charges. Therefore, based on the capacity consumed per charge, the number of times the energy storage battery can be charged from its current available capacity to its minimum available capacity can be calculated, ultimately predicting the number of times each energy storage battery can be charged before entering maintenance mode. Maintenance mode here refers to the state of the energy storage battery where the current available capacity is too low, the power-on time is too long, and the equipment performance can no longer meet the requirements for normal operation.

[0039] It can be seen that the number of times each energy storage battery can be recharged can be predicted by the current available capacity, maximum available capacity, and number of times it has been charged. This number of times can be used to identify the energy storage battery with the most rechargeable times as the primary target energy storage battery for receiving the electricity generated by the thermoelectric conversion device. Ultimately, this ensures that the number of rechargeable times of multiple energy storage batteries in the energy storage device remains basically consistent, extending the overall service life of the energy storage device. When repairing or replacing energy storage batteries, multiple energy storage batteries can be repaired or replaced simultaneously, reducing the maintenance cost of the energy storage device.

[0040] S202: The server obtains the first amount of electricity generated by the thermoelectric conversion device in the first time period, and predicts the second amount of electricity generated by the thermoelectric conversion device in the second time period based on the first amount of electricity; wherein, the first transfer battery is used to continuously store the electrical energy generated by the thermoelectric conversion device, and the first time period is the period before the second time period.

[0041] Specifically, the intermediate battery here is used to temporarily store the electrical energy generated by the thermoelectric conversion device, and under certain conditions, releases the stored electrical energy into the energy storage battery, such as when the electrical energy stored in the intermediate battery reaches a certain value. The server predicts the electrical energy to be generated in the second period based on the first electrical energy generated by the thermoelectric conversion device in the first period, so that the energy storage battery can obtain at least a certain amount of electrical energy when receiving the electrical energy generated by the thermoelectric conversion device.

[0042] In one possible embodiment, the server acquires a first electrical charge generated by the thermoelectric conversion device in a first time period, and predicts a second electrical charge generated by the thermoelectric conversion device in a second time period based on the first electrical charge. This includes: the server acquires the operating ambient temperature of the thermoelectric conversion device; if the operating ambient temperature of the thermoelectric conversion device is greater than a preset temperature, the server acquires the first electrical charge generated by the thermoelectric conversion device in the first time period; the server acquires multiple third electrical charges generated in multiple sub-time periods within the first time period; if the values ​​of the multiple third electrical charges increase sequentially after being sorted by time, the server predicts the second electrical charge generated in the second time period based on the third electrical charge generated in the last sub-time period; if the values ​​of the multiple third electrical charges do not increase sequentially after being sorted by time, the server determines the first electrical charge as the second electrical charge.

[0043] Specifically, please see Figure 3 , Figure 3 Please refer to the schematic flowchart of an embodiment of a charging method based on battery thermal energy provided in this application. Figure 3 Including: S301-S303.

[0044] S301: The server obtains the operating ambient temperature of the thermoelectric conversion device. If the operating ambient temperature of the thermoelectric conversion device is greater than the preset temperature, the server obtains the first amount of electricity generated by the thermoelectric conversion device in the first time period.

[0045] Specifically, the operating ambient temperature of the thermoelectric conversion device can be obtained by measuring the temperature of the heat conduction pipe or by measuring the temperature of the energy storage battery. When the temperature of the thermoelectric conversion device is higher than the preset temperature, the server can anticipate that the energy storage device will continue to operate, and the thermoelectric conversion device will also continue to perform thermoelectric conversion. At this time, the server obtains the first electrical quantity generated by the thermoelectric conversion device in the first time period.

[0046] S302: The server obtains multiple third-level electricity generated in multiple sub-periods within the first time period. If the multiple third-level electricity values ​​are sorted by time and increase in value, the server predicts the second-level electricity generated in the second time period based on the third-level electricity generated in the last sub-period.

[0047] Specifically, if the third electricity generated in multiple sub-periods within the first time period shows an increasing trend in chronological order, it can be determined that the heat generated by the energy storage device is gradually increasing. Therefore, the second electricity generated in the second time period can be predicted based on the third electricity generated in the last sub-period. Here, the multiple sub-periods in the first and second time periods are of the same length. When predicting the second electricity generated in the second time period based on the third electricity generated in the last sub-period, the second electricity generated in the second time period can be determined by multiplying the third electricity generated in the last sub-period of the first time period by the number of sub-periods in the second time period. Alternatively, the server can first calculate the difference in the third electricity generated in each adjacent sub-period of the first time period, then average the multiple differences to obtain the average difference, and then predict the electricity generated in each sub-period of the second time period based on the average difference. Finally, the predicted electricity generated in each sub-period of the second time period is summed to obtain the second electricity generated in the second time period.

[0048] For example, if the first time period includes three sub-time periods, and the third power consumption of the three sub-time periods is arranged in chronological order as 40W, 43W, and 50W, then the third power consumption of the last sub-time period in the third time period is 50W. The difference in third power consumption between each adjacent sub-time period in the first time period includes 3W and 7W. The average difference is 5W. If the second time period includes five sub-time periods, then the second power consumption of the second time period is 50W + 45W + 40W + 35W + 30W = 200W.

[0049] S303: If multiple third battery values ​​do not increase after being sorted by time, the server will determine the first battery value as the second battery value.

[0050] Specifically, if the values ​​of multiple third-order energy quantities do not increase when sorted by time, it indicates that the energy storage device may only operate briefly in the first period, thus causing the values ​​of the multiple third-order energy quantities to not increase when sorted by time. In the second period, the energy storage device is likely to gradually cease operation. In this case, if the thermoelectric conversion device has a transfer battery that can temporarily store electrical energy, this transfer battery will store at least the energy equivalent to the first order of energy, and the server can directly identify the first order of energy as the second order of energy. If the thermoelectric conversion device does not have a transfer battery that can temporarily store electrical energy, and the energy storage battery also requires a certain amount of time to dissipate heat, the thermoelectric conversion device can still continue to receive heat energy in the second period. In this case, the first order of energy can also be identified as the second order of energy.

[0051] It can be seen that by acquiring multiple third electrical quantities generated in various sub-periods within the first time period, and with the third electrical quantities increasing sequentially after being ordered chronologically, the second electrical quantity of the thermoelectric conversion device under continuous operation can be predicted based on the third electrical quantity generated in the last sub-period of the first time period. Conversely, with the third electrical quantities increasing sequentially after being ordered chronologically, the second electrical quantity under the condition that the thermoelectric conversion device gradually stops operating in the second time period can be predicted based on the first electrical quantity. Using different prediction methods under different conditions improves the prediction accuracy of the second electrical quantity.

[0052] In one possible embodiment, before the server acquires the first amount of electricity generated by the thermoelectric conversion device in the first time period and predicts the second amount of electricity generated by the thermoelectric conversion device in the second time period based on the first amount of electricity; the server acquires the current available capacity of the first target energy storage battery; if the current available capacity of the first target energy storage battery is less than the first preset available capacity, the product of the first preset available capacity and the preset ratio is determined as the first preset amount of electricity; if the current available capacity of the first target energy storage battery is not less than the first preset available capacity, the product of the current available capacity and the preset ratio is determined as the first preset amount of electricity.

[0053] Specifically, the first preset charge is calculated by the server based on the available capacity of the first target energy storage battery. Here, available capacity refers to the current actual maximum capacity of the energy storage battery. As the number of repeated charge-discharge cycles increases, the available capacity of the energy storage battery will become increasingly smaller than the designed maximum capacity. When the current available capacity of the first target energy storage battery is less than the first preset available capacity, the product of the first preset available capacity and a preset ratio is determined as the first preset charge. When the current available capacity of the first target energy storage battery is not less than the first preset available capacity, the product of the current available capacity and a preset ratio is determined as the first preset charge. When the second charge achievable by the thermoelectric conversion device is greater than the first preset charge, it proves that the basic charging requirements of the first target energy storage battery can be met.

[0054] S203: If the second power level is greater than the first preset power level, the server obtains the first remaining power level of the first target energy storage battery and determines the energy storage battery in the first target energy storage battery whose first remaining power level is less than the second preset power level as the second target energy storage battery.

[0055] Specifically, when the second power is greater than the first preset power, the energy storage device can obtain at least the electrical energy generated by the thermoelectric conversion device of the first preset power. At this time, the first target energy storage battery with the first remaining power less than the second preset power is identified as the second target energy storage battery. The second target energy storage battery with power demand is identified, and then the electrical energy generated by the thermoelectric conversion device is stored in the second target energy storage battery.

[0056] S204: The server stores the electrical energy generated by the thermoelectric conversion device into the second target energy storage battery during the second time period.

[0057] Specifically, please see Figure 4 , Figure 4 This is a schematic diagram of a thermoelectric conversion device provided in an embodiment of this application. The thermoelectric conversion device is connected to an energy storage device via a heat-conducting pipe. The energy storage battery is sealed in a housing and submerged in coolant. The coolant circulates between the thermoelectric conversion device and the housing through the heat-conducting pipe, carrying heat from the housing to the thermoelectric conversion device. The thermoelectric conversion device converts the heat energy into electrical energy, which is then transmitted back to the energy storage battery in the housing via a connecting circuit. While the electrical energy is being transmitted back to the energy storage battery in the housing, the remaining charge of the second target energy storage battery can be obtained in real time. When the remaining charge exceeds a second preset charge, the supply of electrical energy to the second target energy storage battery is stopped.

[0058] Furthermore, when the server stores the electrical energy generated by the thermoelectric conversion device into the second target energy storage battery during the second time period, it needs to acquire the second remaining power of the second target energy storage battery. When the second remaining power of any second target energy storage battery is greater than a second preset power, the supply of electrical energy to that second target energy storage battery is stopped. When the second remaining power of all second target energy storage batteries is greater than the second preset power, the storage of electrical energy generated by the thermoelectric conversion device into the second target energy storage battery is stopped.

[0059] In one possible embodiment, if the energy storage device includes a first transfer battery and the number of first transfer batteries is greater than a preset number, then the remaining power of each transfer battery in the first transfer battery is obtained; the transfer batteries in the first transfer batteries whose remaining power is greater than a first preset power are determined as target transfer batteries; and the energy of the target transfer batteries is stored in a second target energy storage battery in a second time period.

[0060] Specifically, the transfer battery is used to store the electrical energy generated by the thermoelectric conversion device. When the remaining power of the transfer battery is greater than a first preset power level, it proves that the power stored in the transfer battery can meet the charging needs of at least one energy storage battery. Therefore, the electrical energy stored in the transfer battery can be stored in the energy storage battery that needs charging. The server identifies the transfer battery with a remaining power level greater than the first preset power level as the target transfer battery, and stores the electrical energy of the target transfer battery in the second target energy storage battery during the second time period to meet the charging needs of the second target energy storage battery.

[0061] It can be seen that by setting a first preset power level, the target transfer battery will charge the second target energy storage battery when the power stored in the transfer battery is greater than the first preset power level, instead of charging the second target energy storage battery after the transfer battery has stored some power. Therefore, the number of times the energy storage battery is charged is further reduced, and the overall service life of the energy storage device is extended.

[0062] In one possible embodiment, if the number of first transfer batteries is not greater than a preset number, the power-on duration of multiple energy storage batteries is obtained, and energy storage batteries with a power-on duration less than the preset duration are identified as pre-selected energy storage batteries; the number of rechargeable times of the pre-selected energy storage batteries is obtained, and energy storage batteries with a number of rechargeable times greater than a preset number are identified as second transfer batteries; the remaining power of each transfer battery in the first and second transfer batteries is obtained; transfer batteries in the first and second transfer batteries with a remaining power greater than a first preset power are identified as target transfer batteries; and the energy of the target transfer batteries is stored in the second target energy storage battery in the second time period.

[0063] Specifically, when the number of first relay batteries in the energy storage system is not greater than a preset number, they can be replaced by other energy storage batteries in the energy storage device. Since relay batteries are used frequently, the server first identifies energy storage batteries with a power-on time shorter than a preset time as pre-selected energy storage batteries. Then, among the pre-selected energy storage batteries, those with a rechargeable count greater than a preset number are identified as second relay batteries. Finally, the battery with the best condition and the longest possible usage time is selected as the second relay battery from among multiple energy storage batteries.

[0064] The server obtains the remaining power of each first transfer battery and each second transfer battery, and determines the first transfer battery and the second transfer battery with a remaining power greater than a first preset power as target transfer batteries. In the second time period, the power of the target transfer batteries is stored in the second target energy storage battery to meet the charging needs of the second target energy storage battery.

[0065] It can be seen that when the number of first transfer batteries in the energy storage device is not greater than the preset number, a second transfer battery that meets the conditions is determined from the energy storage batteries. This ensures that there are enough transfer batteries to charge the second target energy storage battery when the stored energy in the transfer batteries is greater than the first preset energy. This allows the second target energy storage battery to store at least the first preset energy at a time, further reducing the number of charging cycles for the energy storage batteries and extending the overall service life of the energy storage device.

[0066] In one possible embodiment, storing the electrical energy of the target transfer battery into the second target energy storage battery during the second time period includes: obtaining a discharge order of multiple target transfer batteries based on their remaining charge; obtaining the battery state of the second target energy storage battery, which can be one of charging, discharging, or energy storage; identifying the energy storage battery in the second target energy storage battery that is in the charging state as the third target energy storage battery; identifying the energy storage battery in the second target energy storage battery that is in the energy storage state as the fourth target energy storage battery; storing the electrical energy in the target transfer battery into the third energy storage battery according to the discharge order during the second time period; obtaining the remaining charge of the third target energy storage battery and the remaining charge of the target transfer battery in real time; if the remaining charge of the third target energy storage battery is greater than a second preset charge, and the remaining charge of the target transfer batteries is not less than a third preset charge, storing the electrical energy in the target transfer battery into the fourth target energy storage battery according to the discharge order.

[0067] Please see Figure 5 , Figure 5 A schematic flowchart of another embodiment of a charging method based on battery thermal energy provided in this application includes: S401-S405.

[0068] S401: The server obtains the discharge order of multiple target transfer batteries based on the remaining power, and obtains the battery status of the second target energy storage battery. The battery status is one of charging, discharging and energy storage.

[0069] Specifically, the remaining power here refers to the real-time remaining power of the target transfer battery at the start of the second time period. The discharge sorting can be based on the remaining power from largest to smallest, or from smallest to largest. The discharge sorting is used to indicate the order in which the multiple target transfer batteries release their stored energy when multiple target transfer batteries exist.

[0070] S402: The server identifies the energy storage battery in the second target energy storage battery that is in the charging state as the third target energy storage battery, and identifies the energy storage battery in the second target energy storage battery that is in the energy storage state as the fourth target energy storage battery.

[0071] Specifically, the second target energy storage battery in the charging state is one that is charged by an external power source under the server's instruction; the second target energy storage battery in the discharging state is one that is discharging to an external electrical appliance under the server's instruction; and the second target energy storage battery in the energy storage state is one that is neither being charged by an external power source nor discharging to an external source. Since the second target energy storage battery in the discharging state needs to meet the power requirements of the external electrical appliance, energy storage batteries in the discharging state cannot be in the discharging state simultaneously. Therefore, the transfer battery only releases power to energy storage batteries in the charging state and energy storage batteries in the energy storage state.

[0072] S403: The server stores the electrical energy in the target transfer battery into the third energy storage battery according to the discharge sequence during the second time period.

[0073] According to the discharge sequence, the electrical energy in the target transfer battery is stored one by one into the third energy storage battery. When the remaining charge of a target transfer battery is less than a fourth preset charge, the release of the stored electrical energy in that target transfer battery stops, and the electrical energy in the next target transfer battery in the discharge sequence is released into the third energy storage battery. The fourth preset charge is determined based on the maximum usable capacity of the target transfer battery, and can be 20%, 10%, etc., of the maximum usable capacity.

[0074] S404: The server obtains the remaining power of the third target energy storage battery and the remaining power of the target transfer battery in real time.

[0075] Specifically, during the process of the third target energy storage battery receiving the energy released by the target relay battery, the server obtains the remaining power of the third target energy storage battery and the remaining power of the target relay battery in real time.

[0076] S405: If the remaining power of the third target energy storage battery is greater than the second preset power, and the remaining power of the target transfer battery is not less than the third preset power, the server stores the energy in the target transfer battery into the fourth target energy storage battery according to the discharge order.

[0077] Specifically, when there are multiple third target energy storage batteries and multiple target transfer batteries, the remaining capacity of the third target energy storage batteries is the remaining capacity of each of the third target energy storage batteries, and the remaining capacity of the target transfer batteries is the remaining capacity of each of the target transfer batteries. When the remaining capacity of all third target energy storage batteries is greater than the second preset capacity, and the remaining capacity of all target transfer batteries is not less than the third preset capacity, it proves that the charging needs of the second target energy storage batteries in the charging state have been met. At this time, there is still remaining capacity in the target transfer batteries, so the energy in the target transfer batteries is stored in the fourth target energy storage battery according to the discharge order.

[0078] It can be seen that by designating the second target energy storage battery as the third and fourth energy storage batteries, the energy in the target transfer battery is first stored in the third energy storage battery with higher charging demand. After the third energy storage battery is fully charged, the energy in the target transfer battery is then stored in the fourth energy storage battery. This further increases the amount of energy stored in a single charge, reduces the number of times the energy storage battery is charged, and improves the overall service life of the energy storage device.

[0079] By implementing the methods in the embodiments of this application, it can be seen that the heat generated by the energy storage battery in the energy storage device during use is converted into electrical energy through the thermoelectric conversion device, saving energy waste caused by the heat dissipation process of the energy storage battery; by predicting the second amount of electricity that the thermoelectric conversion device can provide, it is ensured that the energy storage device can store at least a first preset amount of electrical energy at a time, and repeatedly charge with small amounts of electricity, thereby reducing the number of times the energy storage battery needs to be charged. When the energy storage device includes a first transfer battery, charging the energy storage battery through the transfer battery further increases the amount of electricity that the energy storage battery can be charged at one time, reduces the number of times the energy storage battery needs to be charged, and improves the overall service life of the energy storage device.
