Description

Technical Field

[0001] The present invention relates to the technical field of air pump emergency power supply equipment, and in particular to a lithium battery energy storage and charging integrated machine and a control method thereof. Background Art

[0002] The lithium battery energy storage systems currently on the market are widely used in the field of car charging. They have shown certain effectiveness in daily use, but they also face many challenges. For example, battery performance degradation in high temperature environments and noise pollution caused by insufficient heat dissipation have seriously affected the charging experience of electric vehicle users and the operational reliability of charging facilities.

[0003] Existing lithium battery energy storage systems usually use traditional air cooling or basic liquid cooling technology to cope with high temperature environments. However, these heat dissipation methods often fail to achieve the desired effect under continuous high temperature conditions. Although air cooling is low-cost, it has low cooling efficiency and increases noise pollution. Although liquid cooling technology has a better heat dissipation effect, it is more difficult to design and maintain, and the cooling efficiency is still limited for scenarios with long-term high-temperature operations. In addition, most charging station energy storage systems are not equipped with a comprehensive network communication redundancy mechanism, which greatly threatens the stability of the system when facing a failure of the main communication link, thereby affecting the continuity of the charging service and reducing the user experience and the overall reliability of the system.

[0004] However, existing lithium battery energy storage systems perform poorly in high-temperature environments and cannot guarantee a continuous and stable power supply. Traditional heat dissipation methods are inefficient and cause noise pollution. There is a lack of adequate electrical and physical protection measures, which increases safety risks in abnormal situations. The storage device has a single interface, which limits its versatility and ability to respond to emergencies. The single communication path is susceptible to interference, which reduces the reliability and stability of the system. Therefore, there is room for improvement. Summary of the invention

[0035] The highly compatible connection port array includes multiple AC / DC bidirectional conversion interfaces, which enable seamless switching between AC and DC modes through a precisely designed electronic switch matrix to support a variety of power input and output requirements. The electronic switch matrix is ​​electrically connected to the DC charger and can automatically configure the corresponding input and output paths according to the power type to ensure normal operation under different power conditions.

[0036] The dual-network dual-motherboard dual-channel architecture includes two independently running main control boards and two independent data transmission channels. Each main control board is electrically connected to the adaptive energy management system and is responsible for different data processing tasks to ensure high reliability of data transmission. The link detection mechanism is electrically connected to the adaptive energy management system and periodically evaluates the status of the communication line. Once a potential fault sign is found, the backup path is automatically activated to ensure uninterrupted data transmission.

It is used to remotely monitor and manage the charging status, realize remote fault diagnosis and maintenance, and improve the management level and service quality of the system.

[0038] The implementation principle of a lithium battery energy storage and charging integrated machine in the embodiment of the present application is: Through the collaborative work of the adaptive energy management system, the liquid cooling circulation heat dissipation device, the electrical and physical protection device, the highly compatible connection port array, the dual-network dual-motherboard dual-channel architecture and the wireless communication module, the lithium battery energy storage and charging integrated machine of the present invention can maintain excellent performance and safety under extreme climatic conditions, greatly improving the stability and reliability of the system.

[0039] like Figure 2 As shown, the present application discloses a control method for a lithium battery energy storage and charging integrated machine, which specifically includes the following steps: S10: Acquire the battery pack temperature of the lithium battery energy storage and charging integrated machine in real time, compare the battery pack temperature with a preset temperature threshold, and obtain a comparison result.

[0040] S20: Generate a charging adjustment instruction according to the temperature comparison result, and obtain a current adjustment value in response to the charging adjustment instruction.

[0041] S30: regulating the charging current based on the current adjustment value to obtain an adjusted charging current.

[0042] S40: charging the load according to the adjusted charging current until charging is completed.

[0043] Specifically, the temperature sensor monitors the temperature of the battery pack in real time. When the temperature is lower than the preset threshold T2, the adaptive energy management system will automatically increase the charging current to speed up the charging speed and ensure that the battery pack can quickly return to normal operating temperature in a low temperature environment.

[0044] Secondly, in order to further improve charging efficiency, the adaptive energy management system will enable auxiliary heating devices in low temperature environments to preheat the battery pack through heating elements so that it can reach a suitable operating temperature more quickly. Finally, the system will dynamically adjust the charging algorithm based on the chemical characteristics and temperature changes of the battery to ensure that the battery's charging and discharging performance is maximized in low temperature environments.

[0045] Furthermore, when the temperature sensor detects that the temperature of the battery pack exceeds the preset threshold value T1, the adaptive energy management system will automatically reduce the charging current to reduce the heat generated by the battery and avoid safety hazards caused by overheating. The system will start the liquid cooling circulation heat dissipation device, and through the circulation of the coolant, it will quickly take away the heat of the battery pack and keep it within the ideal temperature range. In addition, the adaptive energy management system also has a temperature compensation function, which can dynamically adjust the charging voltage and current according to the actual temperature changes to ensure that the battery can still be charged efficiently in a high temperature environment.

[0046] In one embodiment, if Figure 3 As shown, the lithium battery energy storage and charging integrated machine control method also includes the steps of: S11: During the charging process, the battery capacity of the battery pack of the lithium battery energy storage charging integrated device is obtained.

[0047] S22: Compare the battery capacity of the battery pack with a preset battery capacity threshold to obtain a battery capacity comparison result.

[0048] S33: generating a discharge rate adjustment instruction according to the battery capacity comparison result, and obtaining a discharge rate adjustment value in response to the discharge rate adjustment instruction.

[0049] S44: regulating the battery discharge rate based on the discharge rate adjustment value until the discharge is completed.

[0050] Specifically, the adaptive energy management system monitors the battery power E1 in real time. If the battery power E1 is lower than the preset threshold value E2, the adaptive energy management system reduces the discharge rate P1 to P2, where P2=P1-ΔP1, and ΔP1 is the preset discharge rate reduction; if the battery power E1 is higher than the preset threshold value E3, the adaptive energy management system increases the discharge rate P2 to P3, where P3=P2+ΔP2, and ΔP2 is the preset discharge rate increase; until the discharge is completed.

[0051] In one embodiment, if Figure 4 As shown, the lithium battery energy storage and charging integrated machine control method also includes the steps of: S111: Collect external environment data D1, including temperature T, humidity H and light intensity L; S222: According to the external environment data D1, the adaptive energy management system calculates the optimal charge and discharge rate P1; S333: adjusting the charge and discharge rate P1 to P2, wherein P2=P1+ΔP1, ΔP1 is the charge and discharge rate adjustment amount based on the external environment data; S444: Repeat the above steps until the charging and discharging are completed.

[0052] Specifically, the adaptive energy management system can dynamically adjust the charge and discharge rate according to external environmental factors (such as temperature, humidity, light intensity, etc.), thereby ensuring the optimal performance of the lithium battery energy storage charger under different environmental conditions. Specifically, when the ambient temperature is too high, the system will automatically reduce the charge and discharge rate to avoid battery overheating, resulting in performance degradation and safety hazards; while under low temperature or suitable conditions, the system will appropriately increase the charge and discharge rate, shorten the charging time, and improve energy efficiency. In addition, by comprehensively considering factors such as humidity and light intensity, the system can further optimize the charge and discharge strategy to ensure stable and efficient charging services in various complex environments.
