Description

Technical Field

[0001] The present invention specifically relates to an intelligent power supply system and an application method thereof, and belongs to the technical field of battery management. Background Art

[0002] At present, battery packs have been widely used in many fields. Generally speaking, when using battery packs, they need to be controlled by a battery management system to calculate the power of a single battery or cell in the battery pack, protect the battery, control the power balance between batteries, and communicate signals inside and outside the battery management system.

[0003] However, the focus of existing battery management systems is usually limited to the management of a single battery pack, and it is basically unable to accurately modulate the working mode, input and output power, and voltage of the battery pack in a timely manner according to different actual needs. For example, the existing technology can only solve the protection of charging overvoltage, charging overcurrent, discharging undervoltage, discharging overcurrent, battery overtemperature, etc., and cannot make adaptive adjustments according to the charging power supply and discharging load. It can only provide four simple modes such as allowing charging or not allowing charging, allowing discharging or not allowing discharging, and cannot achieve controllable input and output of current. Summary of the invention

[0004] The object of the present invention is to provide an intelligent power supply system and an application method thereof to overcome the deficiencies in the prior art.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] Some embodiments of the present invention provide an intelligent power supply system, which includes an energy control module and an intelligent module connected to a battery module;

[0007] Wherein, the intelligent module is at least used for:

[0009] Control the input and output power and voltage of the energy control module;

[0010] The energy control module is at least used to modulate the input and output power of the battery module according to the real-time power and voltage requirements given by the intelligent module.

[0011] In some embodiments, the intelligent module calculates the working performance parameters of the battery module based on the real-time data and historical data of the battery module in the following manner:

[0012] The maximum output power of the battery module is obtained by multiplying the maximum input-output ratio allowed at different charge states of the single battery or cell constituting the battery module by the available capacity of the battery module, and then multiplying it by the voltage of the battery module, where the available capacity of the battery module is calculated in Ah;

[0013] The remaining capacity of the battery module is obtained by adding or subtracting the accumulated discharge or charge capacity obtained by current integration from the available capacity of the battery module, and setting voltage correction points at different charge states of the single batteries or cells constituting the battery module to reduce the accumulated error caused by current integration;

[0014] The remaining life of the battery module is obtained by taking the standard life test data of the battery module as the benchmark for the life attenuation according to the number of times, and adding the remaining cycle life parameter obtained by linearly interpolating the actual available capacity between the initial capacity and 80% of the rated capacity.

[0015] The available capacity of the battery module is obtained by subtracting the attenuation according to the number of times in the standard life attenuation of the battery module from the initial capacity of the battery. When the single battery or cell constituting the battery module has a connected charging voltage protection and a discharging voltage protection, the available capacity is corrected according to the capacity integral during the previous and subsequent charging protections and discharging protections to obtain the available capacity of the battery module.

[0016] The available capacity of the battery module is multiplied by (1-SOC%) to obtain the available input power of the battery module.

[0017] In some embodiments, the smart module is connected to one or more of a server, a smart terminal, and other external smart devices through a communication module.

[0018] In some embodiments, the intelligent module controls the input and output power and voltage of the energy control module by receiving information from at least one of a server, an intelligent terminal, and other external intelligent devices.

[0019] In some embodiments, the operating modes of the intelligent power system include an input mode, an output mode, and a self-test mode;

[0020] Wherein, in the input mode, the intelligent module adjusts the input power of the energy control module according to the maximum input power of the battery module and the AIC information of the battery module, and obtains the total input power by integrating the current over time. When the total input power reaches the AIC of the battery module, the energy control module is turned off to stop the input;

[0021] In the output mode, the intelligent module controls the energy control module to output according to the maximum output power and SOC of the battery module and the external required output power and output voltage requirements, and in accordance with the principle of taking the smaller of the maximum output power and the required output power, and when the total output power reaches the battery module SOC, the energy control module is turned off and the output is stopped. The source of the external required output power and output voltage requirements includes at least one of a server, an intelligent terminal and other external intelligent devices connected to the intelligent module;

[0022] In the self-test mode, the intelligent module calculates the individual SOC values ​​of the single battery, battery cell or battery string formed by connecting multiple single batteries in series and / or in parallel, which constitute the battery module, based on the real-time data and historical data of the battery module, and then releases the individual power of the single battery, battery cell or battery string with an individual SOC value higher than the average value through a controllable bypass circuit, so as to reduce the SOC of the single battery, battery cell or battery string to the average value.

[0023] In some embodiments, the working mode of the intelligent power system further includes a parallel mode, in which a collaborative algorithm is performed on an intelligent terminal or server connected to the intelligent modules in the plurality of intelligent power systems, including:

[0024] According to the load conditions, the external discharge power of each intelligent power system is distributed according to the proportion of the remaining power of the battery modules in each intelligent power system, and the output power of each corresponding energy control module is fine-tuned according to the maximum output power of each battery module;

[0025] According to the charging power, the actual input power of each battery module is allocated according to the inverse ratio of the input power of the power module in each intelligent power system, and the input power of each corresponding energy control module is fine-tuned according to the maximum input power of each battery module.

[0026] Some embodiments of the present invention also provide application solutions of the intelligent power supply system in multiple fields.

[0027] Compared with the prior art, the intelligent power supply system provided by the above embodiments of the present invention has at least the following advantages:

[0028] (1) It greatly expands the adaptability to charging power sources. It can actively adjust according to the characteristics of the charging power source and the module itself. Even if the external power source cannot charge directly, it can still achieve charging reception for the external low-voltage power source or high-power power source without damaging the battery itself through internal adaptive operation, instead of only being able to shut down.

[0029] (2) It greatly expands the adaptability to discharge loads. It can actively adjust according to the discharge load and the characteristics of the module itself. Even if the external load changes, it can discharge the external load with different voltage requirements through internal adaptive operation, or drive large loads through parallel connection of modules without damaging the battery itself.

[0040] Furthermore, the intelligent module is connected to one or more of the server, the intelligent terminal and other external intelligent devices through a communication module. The communication module may be built-in to the intelligent power system or disposed outside the intelligent power system. The communication module may be wired or wireless (e.g., wifi, bluetooth communication module, etc.).

[0041] Furthermore, the intelligent module controls the input and output power and voltage of the energy control module by receiving information from at least one of a server, an intelligent terminal and other external intelligent devices.

[0042] Among them, the "other external smart devices" are external smart devices that are different from servers and smart terminals, and can be selected from all devices with communication and computing functions, such as computers, smart two-wheeled vehicles, electric vehicles or household appliances, etc.

[0043] The intelligent terminal includes but is not limited to a computer, MCU, smart phone, tablet computer or other intelligent devices.

[0044] Furthermore, the intelligent module can be used locally or by using a server connected to the intelligent module to calculate the real-time data of the battery module and the historical data stored locally or on the server remotely or in the cloud, thereby providing the maximum output and input power of the battery module and the remaining power (SOC), remaining life (SOH), module available capacity (ATC), available input power (AIC) and other information. The calculation methods used include:

[0045] The maximum output power of the battery module is obtained by multiplying the maximum input-output ratio allowed at different charge states of the single battery or cell constituting the battery module by the available capacity of the battery module, and then multiplying it by the voltage of the battery module, where the available capacity of the battery module is calculated in Ah;

[0046] The remaining capacity of the battery module is obtained by adding or subtracting the accumulated discharge or charge capacity obtained by current integration from the available capacity of the battery module, and setting voltage correction points at different charge states of the single batteries or cells constituting the battery module to reduce the accumulated error caused by current integration;

[0047] The remaining life of the battery module is obtained by taking the standard life test data of the battery module as the benchmark for the life attenuation according to the number of times, and adding the remaining cycle life parameter obtained by linearly interpolating the actual available capacity between the initial capacity and 80% of the rated capacity.

[0048] The available capacity of the battery module is obtained by subtracting the attenuation according to the number of times in the standard life attenuation of the battery module from the initial capacity of the battery. When the single battery or cell constituting the battery module has a connected charging voltage protection and a discharging voltage protection, the available capacity is corrected according to the capacity integral during the previous and subsequent charging protections and discharging protections to obtain the available capacity of the battery module.

[0049] The available capacity of the battery module is multiplied by (1-SOC%) to obtain the available input power of the battery module.

[0050] Furthermore, the working modes of the intelligent power supply system include an input mode, an output mode and a self-test mode.

[0051] Among them, in the input mode, the intelligent module adjusts the input power of the energy control module according to the maximum input power of the battery module and the AIC information of the battery module, and obtains the total input power by integrating the current over time. When the total input power reaches the AIC of the battery module, the energy control module is turned off and the input is stopped.

[0052] In the output mode, the intelligent module controls the energy control module to output according to the maximum output power and SOC of the battery module and the external required output power and output voltage requirements, in accordance with the smaller principle of the maximum output power and the required output power, and when the total output power reaches the SOC of the battery module, the energy control module is turned off and the output is stopped. The sources of the external required output power and output voltage requirements include at least one of a server, an intelligent terminal and other external intelligent devices connected to the intelligent module.

[0053] In the self-checking mode, the intelligent module calculates the individual SOC values ​​of the single battery, battery core or battery string formed by multiple single batteries connected in series and / or in parallel, which constitutes the battery module, based on the real-time data and historical data of the battery module, and then releases the individual power of the single battery, battery core or battery string with an individual SOC value higher than the average value through a controllable bypass circuit, so as to reduce the SOC of the single battery, battery core or battery string to the average value. Furthermore, in the self-checking mode, the intelligent module performs one or more actions until the SOC of each single battery, battery core or battery string in the battery module is the same or close.

[0054] Furthermore, the working mode of the intelligent power system also includes a parallel mode. In the parallel mode, a collaborative algorithm will be performed on the intelligent terminal or server connected to the intelligent modules in multiple intelligent power systems, including:

[0055] According to the load conditions, the external discharge power of each intelligent power system is distributed according to the proportion of the remaining power of the battery modules in each intelligent power system, and the output power of each corresponding energy control module is fine-tuned according to the maximum output power of each battery module;

[0057] Furthermore, the maximum input and output power of the battery module = the intrinsic maximum charge and discharge rate R of the single battery or cell * available capacity * battery module voltage * l, where R is related to SOC and temperature, and I is the number of cycles of the battery module.

[0058] More specifically, the maximum input and output power of the battery module is the maximum charge and discharge rate at different temperatures and SOCs based on the intrinsic maximum input and output performance of the battery cells that make up the battery module when the batteries are grouped. The data is obtained after correction based on the SOC, temperature, available capacity, module voltage, number of cycles and other conditions of the battery module at that time, that is, the intrinsic maximum charge and discharge rate of the battery cell R (SOC, temperature) * available capacity * module voltage * l (number of cycles).

[0059] Furthermore, the available capacity of the battery module=initial capacity of the battery module*temperature correction coefficient*(1-life correction coefficient*number of cycles), and when the available capacity correction condition is met, the integral value is selected as the next initial capacity calculation value.

[0060] More specifically, the available capacity of the battery module is obtained based on the initial capacity of the battery, plus the life correction factor, the temperature correction factor, and the cumulative calculation and correction of the cycle capacity. It represents the current maximum available capacity of the module, that is: initial capacity C0 (temperature) * (1-life correction factor * number of cycles). At the same time, when the available capacity correction conditions are met, the integral value is selected as the next initial capacity calculation value.

[0061] Furthermore, the remaining power SOC of the battery module is obtained by integrating the charging capacity and discharging capacity according to the available capacity ATC of the battery module by current, combining the battery capacity obtained after the initial capacity of the battery module, and then dividing by the available capacity of the battery module to obtain the value, which is expressed as a percentage.

[0062] Furthermore, the battery module includes a plurality of single batteries or cells connected in series and / or in parallel, and the battery module is also connected to the intelligent module and the energy control module respectively through a signal line and a power line.

[0063] Furthermore, the battery module is also connected to one or more sensor modules, and the sensor module includes any one or a combination of multiple current sensors, temperature sensors and voltage sensors.

[0064] Furthermore, the battery module also includes a controllable SOC regulating circuit cooperating with each battery string, and the controllable SOC regulating circuit is at least used to regulate the SOC of a single battery string by releasing electricity through a controllable current bypass.

[0065] Furthermore, the intelligent module can perform calculations of SOC, AIC, SOH, etc. according to the calculation methods listed above, and can also connect to servers, intelligent terminals, and other external intelligent devices to accept external instructions, control the input and output of the energy control module, and the SOC adjustment action of the battery module.

[0066] Furthermore, the energy control module includes a bidirectional voltage modulation circuit, and the bidirectional voltage power modulation circuit has at least the following functions:

[0067] a. Ability to adjust the current duty cycle of the battery module input according to the real-time charging power demand given by the intelligent module, so as to adjust the input power not to exceed the maximum input power / current of the battery module;

[0068] b. According to the real-time charging voltage requirement given by the intelligent module, the external power supply can be adjusted to increase the charging voltage by adjusting the duty cycle to meet the voltage requirement for charging the battery module;

[0069] c. Ability to adjust the current duty cycle during output according to the real-time output power given by the intelligent module, thereby adjusting the output power of the battery module;

[0070] d. It can adjust the current duty cycle during output according to the real-time output voltage requirements given by the intelligent module, thereby adjusting the output voltage.

[0071] For further information, see Figure 2 As shown, the bidirectional voltage modulation circuit includes a BUCK circuit, which can adjust the duty cycle of the current through a high-frequency switch to control the power. The bidirectional voltage modulation circuit is formed by connecting two voltage modulation circuits, one positive and one negative, in parallel, and the current can only pass through one of the voltage modulation circuits through a diode.

[0072] The intelligent power supply system provided by the aforementioned typical embodiments of the present invention can be applied in many aspects.

[0073] For example, the intelligent power system can be connected to an external motor, and the input and output behaviors of the energy control module can be adjusted through instructions from one or more of other external intelligent devices, intelligent terminals, and servers to achieve motor operation control so that the motor outputs torque. Other external intelligent devices can be steering wheels, accelerators, handlebars of light vehicles, control panels of fitness equipment, etc., but are not limited thereto.

[0074] For another example, the smart power system can be connected to an external motor, and receive the energy of the motor's reverse operation through instructions from one or more of other external smart devices, smart terminals, and servers, and store it in the battery module. Other external smart devices can be control panels of fitness equipment, etc., but are not limited thereto.

[0075] For another example, the intelligent power supply system can adjust the output voltage of the energy control module through instructions from other external intelligent devices, intelligent terminals, and servers, thereby outputting currents of different voltage levels to charge digital products such as mobile phones, pads, and notebooks, and can also provide high-voltage output for household appliances such as electric kettles and refrigerators.

[0076] For another example, multiple smart power systems can be set up in parallel, and the smart module of one of the smart power systems can be used as the main server, or the multiple smart power systems can be connected to an external server so that the multiple smart power systems can be used in parallel to achieve output power and input power requirements that cannot be met by a single module. It can realize the storage of solar, wind and other energy after conversion into electrical energy, and drive larger electrical appliances, that is, meet the requirements of large output power and / or large input power.

[0077] The intelligent power supply system provided by the above embodiments of the present invention can accurately modulate the working mode, input and output power and voltage of the battery pack in a timely manner according to different actual needs. On the one hand, it greatly expands the adaptability to the charging power supply, and can actively adjust according to the characteristics of the charging power supply and the module itself, so that even if the external power supply cannot be charged directly, it can realize charging reception of the external low-voltage power supply or high-power power supply without damaging the battery itself through internal adaptive operation, instead of only being able to shut down; on the other hand, it also greatly expands the adaptability to the discharge load, and can actively adjust according to the discharge load and the characteristics of the module itself, so that even if the external load changes, it can realize discharging of external loads with different voltage requirements through internal adaptive operation, or realize driving of large loads through parallel connection of modules without damaging the battery itself.
