Description

Technical Field

[0001] The present invention belongs to the field of underwater charging technology, and specifically relates to a multi-working condition reconfiguration battery pack and power regulation method for underwater equipment based on wireless energy communication technology. Background Art

[0002] During their service life, underwater equipment typically experiences at least two phases: low-power, low-speed cruising and high-power, high-speed sailing. These phases require different voltage and current. As the underwater equipment dives to varying depths, the power system requirements also vary significantly. Generally, the voltage and current requirements increase exponentially when switching from low to high speed. Traditional underwater equipment uses fixed battery packs, consisting of multiple battery blocks connected in a fixed series-parallel physical topology. The output voltage and current of the battery pack can only be adjusted through circuit components such as rectifiers and voltage regulators to meet the power requirements of the underwater equipment during different sailing phases. However, this adjustment method is limited in power regulation across multiple operating conditions due to the complexity of the hardware and control systems. Typically, hardware programming is pre-designed based on the requirements of two or three operating conditions, allowing for corresponding adjustments when needed. Furthermore, the power adjustment process can cause significant heating in the battery pack, reducing its energy efficiency. In addition, when the battery pack fails or the energy is insufficient, the underwater equipment needs to be surfaced and personnel need to be salvaged. After the battery pack is replaced, the underwater equipment needs to be re-deployed and submerged. The energy replenishment process is repetitive, time-consuming and costly, and the operation is difficult to conceal. Summary of the Invention

[0003] The purpose of the present invention is to solve the problems of limited power regulation of existing underwater equipment battery packs, low energy utilization of battery packs caused by thermal effects, cumbersome battery pack replacement process and poor operation concealment, and provide a multi-condition reconstruction battery pack and power regulation method for underwater equipment based on wireless energy communication technology.

[0004] To achieve the above objectives, the technical solutions provided by the present invention are:

[0005] A multi-condition reconfigurable battery pack for underwater equipment based on wireless energy communication technology, wherein the reconfigurable battery pack includes multiple layers of battery modules, each layer of battery modules includes multiple battery cells, and a single battery cell is composed of several battery blocks connected in series;

[0006] A secondary MCU is provided in each battery cell, and a secondary wireless energy communication transmission device is provided at both the input and output ends of the battery cell; the secondary wireless energy communication transmission device is connected to the primary wireless energy communication transmission device of the underwater charging base station to achieve energy replenishment of the reconstructed battery pack;

[0008] The underwater equipment control system can send a battery pack reconstruction instruction to the secondary MCU of the battery cell according to the voltage, current, and power requirements of the underwater equipment to be performed and the current battery pack output parameter size;

[0009] The secondary MCU is used to control the secondary wireless energy communication and transmission device of the battery cell to be turned on or off according to the battery pack reconstruction instruction sent by the underwater equipment control system to realize battery pack reconstruction; and is used to obtain the charge state of the battery cell in real time when the reconstructed battery pack is replenished with energy and feed it back to the primary wireless energy communication and transmission device.

[0013] The secondary MCU is used to obtain the charge state of the battery cell in real time and feed it back to the primary MCU when the reconstructed battery pack is replenished with energy. The primary MCU is used to determine whether the battery cell is full based on the charge state of the battery cell, and can output a cut-off signal when the battery cell is full to cut off the receiving coil of the secondary wireless energy signal transmission device corresponding to the battery cell.

[0014] Furthermore, the primary MCU can control the primary isolation transformer to inject the data signal output by the primary MCU into the primary compensation circuit through the primary modulation and demodulation module in a high-order harmonic manner;

[0015] The secondary MCU of the battery cell can control the secondary isolation transformer to inject the data signal output by the secondary MCU into the secondary compensation circuit through the secondary modulation and demodulation module in a high-order harmonic manner.

[0017] Step 1: Establish a database of voltage, current, power and number of battery cells required by underwater equipment at different navigation stages, and embed the database into the underwater equipment control system;

[0018] Step 2: The underwater equipment control system communicates with the underwater base station, controls the underwater equipment to connect with the underwater charging base station, and performs energy replenishment.

[0019] Step 3: The underwater equipment control system obtains the current output power, voltage, and current of the reconstructed battery pack in the underwater equipment, and determines whether the current output power, voltage, and current meet the requirements of the underwater equipment's upcoming mission. If so, the underwater equipment directly executes the corresponding mission; if not, proceed to step 4 to reconstruct the battery pack.

[0020] Step 4: The secondary MCU of each battery cell obtains the current temperature, voltage, current, and available capacity data of the corresponding battery cell and uploads the data to the underwater equipment control system. The underwater equipment control system performs a safety diagnosis on the battery cell based on the received current temperature, voltage, current, and available capacity data of the battery cell. If the battery cell is determined to be an abnormal battery cell, the location information of the abnormal battery cell is obtained. If the battery cell is determined to be a normal battery cell, the location information of the normal battery cell is obtained and the process proceeds to step 5.

[0026] In step 2.2, the primary wireless energy communication and simultaneous transmission device determines whether the battery cell is fully charged based on the obtained state of charge of each battery cell. When the state of charge is 0-1, it indicates that the battery cell is not fully charged. When the state of charge is 1, it indicates that the battery cell is fully charged. The primary MCU outputs a disconnect signal to control the receiving coil of the secondary wireless energy communication and simultaneous transmission device corresponding to the battery cell to disconnect.

[0027] Step 2.3: After all battery cells are fully charged, the reconstructed battery pack is fully charged, and the underwater equipment control system controls the underwater equipment to leave the underwater charging base station.

[0028] Furthermore, in step 4, the specific process of performing safety diagnosis on the battery cell is as follows:

[0029] Step 4.1, obtain the safe voltage range, safe current range, safe temperature range and rated capacity of the battery pack;

[0030] Step 4.2: Obtain the current voltage, current, temperature, and available capacity of each battery block in the battery cell, and determine whether the current voltage, current, and temperature are within the safe voltage range, safe current range, and safe temperature range, respectively, and whether the available capacity is higher than a set ratio of the rated capacity. If all of these are true, the battery is normal; if any of these are false, the battery is faulty.

[0031] Step 4.3, based on the fault judgment result of the battery blocks in the battery cell in step 4.2, determine whether the battery cell is normal: if any battery block is a faulty battery, the battery cell is an abnormal battery cell; if all battery blocks in the battery cell are normal batteries, the battery cell is a normal battery cell.

[0032] The advantages of the present invention are:

Secondary wireless energy communication simultaneous transmission devices are provided at both ends of the battery cells. A database of voltage, current, power, and number of battery cells required for different navigation phases of the underwater equipment is pre-set in the underwater equipment control system. During the service life of the underwater equipment, the underwater equipment control system can control the on / off of the battery cells according to the navigation requirements of the underwater equipment, adjusting the series and parallel connection relationship of the battery cells in the battery pack so that the output power of the reconfigurable battery pack meets the navigation power requirements of the underwater equipment.

[0043] The following describes in detail embodiments of the present invention. The embodiments are exemplary and intended to explain the present invention, but are not to be construed as limiting the present invention.

[0044] Reference Figure 1-Figure 2 The multi-operating-condition reconfigurable battery pack for underwater equipment based on wireless energy communication technology includes multiple layers of battery modules. Each layer of the battery module includes multiple battery cells 1, and each battery cell 1 is composed of several battery blocks connected in series. Specifically, the number of battery module layers and the number of battery cells in each layer of the battery module are calculated based on the maximum voltage and maximum current required by the underwater equipment during service. Because the voltage provided by a single battery block is far less than the requirements of the underwater equipment, the present invention uses multiple battery blocks connected in series to form a battery cell. If a battery block fails, the entire battery cell can be directly replaced, avoiding the complexity of assembling a battery pack using individual battery blocks and replacing them in the event of a failure.

[0045] The battery cells are equipped with secondary MCUs, and both the input and output terminals of the battery cells are equipped with secondary wireless energy communication transmission devices 2. The underwater equipment control system pre-installs a database of the voltage, current, power, and number of battery cells required for the underwater equipment to perform different tasks. Based on the power requirements of the underwater equipment's tasks and the current output voltage, current, and power of the battery pack, the underwater equipment control system can send reconfiguration instructions to the secondary MCUs of the battery cells. The secondary MCU controls the secondary wireless energy communication transmission devices on the battery cells based on the reconfiguration instructions, turning them on or off, thereby reconfiguring the battery pack.

[0046] The primary wireless energy communication simultaneous transmission device 3 of the underwater charging base station is used to connect with the primary wireless energy communication simultaneous transmission device 3 of the underwater charging base station to charge the reconstructed battery pack through wireless energy communication technology.

[0047] In the embodiment of the present invention, the underwater equipment multi-condition reconfiguration battery pack includes two layers of battery cells, each layer includes three rows and three columns, a total of nine battery cells. Assume that the voltage provided by each battery cell is , the current is , the corresponding upper and lower battery cells can provide a size of 2 when connected in series. If we first The upper and lower battery cells corresponding to the group are connected in series and then in parallel to form a battery pack. The battery pack can provide a size of

[0048] It can be seen from this that the battery cells in the underwater equipment multi-condition reconfiguration battery pack of the embodiment of the present invention have 18 series-parallel combinations, which can provide a voltage of or 2 , the current is A total of 18 voltage and current combinations are available to meet the different power requirements of underwater equipment.

[0049] Reference Figure 3 The primary wireless energy signal transmission device 3 includes a primary MCU, a primary isolation transformer, a primary modem module, a DC power supply, an inverter, a primary compensation circuit, and a transmitting coil. The primary MCU is connected to the primary modem module via the primary isolation transformer, and the DC power supply, inverter, primary compensation circuit, and transmitting coil are connected in sequence. The primary modem module interacts with the primary compensation circuit to inject the data signal output by the primary MCU into the primary compensation circuit. During energy replenishment, the primary MCU can determine whether a battery cell is fully charged based on the current state of charge of the battery cell transmitted by the secondary MCU.

[0050] The secondary wireless energy communication and transmission device 2 includes a secondary isolation transformer, a secondary modulation and demodulation module, a receiving coil, a secondary compensation circuit, and a rectifier. The secondary modulation and demodulation module is connected to the secondary MCU of the battery cell 1 via the secondary isolation transformer. The receiving coil, secondary compensation circuit, and rectifier are connected in sequence, and the battery cell 1 is connected to the rectifier as a load battery. The secondary modulation and demodulation module interacts with the secondary compensation circuit and is used to inject the data signal output by the secondary MCU into the secondary compensation circuit. The secondary MCU of the battery cell 1 can control the secondary isolation transformer to inject the data signal output by the secondary MCU into the secondary compensation circuit through the secondary modulation and demodulation module in a high-order harmonic manner. The secondary MCU is used to collect the current state of charge of the battery cell during energy replenishment, and transmit the information to the primary MCU via the secondary wireless energy communication and transmission device 2 and the primary wireless energy communication and transmission device 3. The receiving coil of the secondary wireless energy communication and transmission device 2 is turned on or off according to the control instructions of the primary MCU.

[0051] The primary MCU can control the primary isolation transformer to inject the data signal output by the primary MCU into the primary compensation circuit through the primary modulation and demodulation module in a high-order harmonic manner. At the same time, the DC power output by the DC power supply is processed by the inverter and input into the primary compensation circuit to obtain a mixed signal of energy and data signal. The mixed signal is coupled to the secondary compensation circuit through the alternating electromagnetic field generated by the transmitting coil and the receiving coil. The mixed signal is separated from the data signal by the secondary modulation and demodulation module. The data signal is transmitted to the secondary MCU of the battery block through the secondary isolation transformer, and the energy is rectified by the rectifier and then transmitted to the battery cell.

[0052] Reference Figure 4 The method for reconfiguring a multi-condition battery pack of underwater equipment based on wireless energy communication technology includes the following steps:

[0053] Step 1: Establish a database of voltage, current, power and number of battery cells required for underwater equipment in different navigation phases, and embed the database into the underwater equipment control system.

[0054] Step 2: The underwater equipment control system communicates with the underwater charging base station to control the underwater equipment to dock with the underwater charging base station for energy replenishment.

[0055] During the energy replenishment process, each battery cell's secondary MCU acquires the corresponding battery cell's state of charge (SOC) in real time and transmits it to the primary wireless energy communication device of the underwater charging base station via the battery cell's secondary wireless energy communication device. The primary MCU of the primary wireless energy communication device uses the acquired SOC to determine whether the battery cell is fully charged. If the SOC is between 0 and 1, the battery cell is not fully charged. If the SOC is 1, the battery cell is fully charged, and the primary MCU outputs a disconnect signal, disconnecting the receiving coil of the corresponding battery cell's secondary wireless energy communication device. Once all battery cells are fully charged, the reconfigured battery pack is fully charged, and the underwater equipment control system controls the underwater equipment to detach from the underwater charging base station.

[0056] In step 3, the underwater equipment control system obtains the current output power, voltage, and current of the reconstructed battery pack in the underwater equipment, and determines whether the current output power, voltage, and current meet the requirements of the underwater equipment to be performed. If so, the underwater equipment directly performs the corresponding task; if not, enter step 4 to reconstruct the battery pack and adjust the series and parallel connection of the battery cells.

[0057] In step 4, the secondary MCU of each battery cell obtains the current temperature, voltage, current and available capacity data information of the corresponding battery cell, and uploads the data information to the underwater equipment control system; the underwater equipment control system performs safety diagnosis on the battery cell based on the received current temperature, voltage, current and available capacity data information of the battery cell: if the battery cell is determined to be an abnormal battery cell, the location information of the abnormal battery cell is obtained; if the battery cell is determined to be a normal battery cell, the location information of the normal battery cell is obtained and the process goes to step 5.

[0058] In the embodiment of the present invention, since a battery cell is composed of three battery blocks connected in series, if the voltage of any battery block is not within the safe range, the battery block may experience overvoltage or undervoltage problems during charging; if the battery block temperature exceeds the safe temperature range, it may cause thermal runaway problems; at the same time, when the available capacity of a battery block is lower than a certain percentage of the rated capacity, the battery block is considered to have aged, posing a safety risk and cannot be used further. Therefore, it is necessary to perform safety diagnosis on each battery cell. The specific process is as follows:

[0059] Step 4.1: Obtain the safe voltage range, safe current range, safe temperature range, and rated capacity of the battery pack.

[0060] Step 4.2, obtain the current voltage, current, temperature and available capacity of the battery block, determine whether the current voltage, current and temperature are within the safe voltage range, safe current range and safe temperature range respectively, and determine whether the available capacity is higher than the set proportion of the rated capacity. If all are yes, it is a normal battery; if any one is no, it is a faulty battery.

[0061] In this embodiment, when the available capacity of a battery block is lower than 80% of the rated capacity, the battery block is considered to be aged and cannot be used any further.

[0062] Step 4.3, based on the fault judgment result of the battery block in the battery cell in step 4.2, determine whether the battery cell is normal: if any battery block is a faulty battery, the battery cell is an abnormal battery cell; if all three battery blocks are normal batteries, the battery cell is a normal battery cell.

[0063] In step 5, the underwater equipment control system outputs an isolation instruction to the secondary MCU of each abnormal battery cell according to the position information of the abnormal battery cell, controls the shutdown of the abnormal battery cell, and isolates the abnormal battery cell.

[0064] Step 6: The underwater equipment control system determines the normal battery cells involved in the reconstruction based on the voltage, current and power requirements of the underwater equipment's task to be performed, and obtains a battery pack reconstruction plan.

[0065] Step 7. According to the battery pack reconstruction plan obtained in step 6, the underwater equipment control system outputs a reconstruction instruction to the secondary MCUs of all normal battery cells participating in the reconstruction. The secondary MCUs of the normal battery cells participating in the reconstruction output a conduction control signal and control the conduction of the secondary wireless energy signal transmission devices at the input and output ends of the normal battery cells participating in the reconstruction, thereby realizing battery pack reconstruction.

[0066] After the battery pack is reconfigured, the underwater equipment can perform cruise missions or other tasks as required. After each mission, it needs to return to the underwater charging base station for energy replenishment.

[0067] Reference Figure 5 ,When underwater equipment is cruising at low speed and low power, due to the large internal resistance of the load, it is necessary to increase the ,number of parallel battery cells in the reconstructed battery pack to increase the output current and ,satisfy the cruising power requirements; Figure 5 The left figure in the middle shows the series-parallel connection of battery cells in the battery pack of underwater equipment in the low-speed, low-power cruising stage in the embodiment. At this time, the battery pack is composed of three battery cells in parallel. When the underwater equipment needs to enter the mission execution stage, the underwater equipment requires a higher speed and greater power. If the power output of the current series-parallel reconstruction battery pack cannot meet the power requirements of the underwater equipment in the mission execution stage, it is necessary to increase the output voltage of the reconstruction battery pack by connecting multiple battery cells in series to meet the power requirements of the mission execution stage; Figure 5 The middle right figure shows the series-parallel connection of battery cells in a battery pack for underwater equipment during high-speed, low-power cruising. Two battery cells in the upper battery module are first connected in series with the corresponding two battery cells in the lower battery module. These series-connected cells are then connected in parallel to form the required battery pack. This power regulation is controlled by the underwater equipment control system.

[0068] The above description is only a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed in the present invention, and these modifications or replacements should all be included in the scope of protection of the present invention.
