[0037] Embodiment one

[0038] Figure 1 A schematic diagram of a battery pack non-power outage core capacity system provided by the embodiment one of the present application, the system comprises:

[0039] a charger (S1), a direct current load (S2), a core capacity load (S3), a switching module (S4), a battery pack (S5) and a control module (S6);

[0040] The battery pack comprises a plurality of batteries, and the number of the switching modules matches the number of the batteries in the battery pack; the switching module is a parallel connection of a boost unit and a first type of control switch, and each boost unit is provided with an on-off switch; the core capacity load comprises a core capacity resistor;

[0041] The charger is connected to the battery pack, each battery in the battery pack is connected to the direct current load through a matching switching module, the core capacity load is connected to each battery in the battery pack, and a second type of control switch is arranged on each connection branch; the control module is connected to the core capacity load, each switching module and each battery in the battery pack;

[0042] The control module is configured to control each first-type control switch to be in a closed state and each second-type control switch to be in an open state in a non-nuclear capacity state, and to control each first-type control switch to be in an open state, control the on-off switch of the voltage boosting unit in the target switching module matched with the target nuclear capacity battery selected as a target of nuclear capacity power supply to be in an open state, and control the on-off switches of other voltage boosting units to be in a connected state after each first-type control switch is in an open state in a nuclear capacity state; and control the target second-type control switch on the connection branch between the nuclear capacity load and the target battery selected as the target of nuclear capacity power supply to be in a closed state.

[0043] For ease of understanding, as shown in Figure 1 The battery pack is composed of at least two single batteries. Since only one single battery is used for nuclear capacity each time, in the battery pack composed of at least two single batteries, one is a nuclear capacity battery and the rest are non-nuclear capacity batteries, and the non-nuclear capacity batteries are used to continuously supply power to the DC load. Before the nuclear capacity task is performed, the charger ensures that each single battery in the battery pack is in a full power state. The switching module refers to a functional module that specifically implements the switching of the battery pack between the nuclear capacity state and the non-nuclear capacity state, and is composed of a voltage boosting unit and a line with a first-type control switch, that is, the first-type control switch is also an isolation switch on the branch matched with the battery. The voltage boosting unit, that is, a DC / DC converter, can increase the DC power provided by the battery from the current level voltage to another level voltage to meet the voltage requirement of the DC load when one of the batteries stops supplying power to the DC load, so that the remaining batteries in the battery pack can also meet the voltage requirement of the DC load, thereby realizing uninterrupted nuclear capacity.

[0044] The nuclear capacity resistance is used to carry the electric energy released by the nuclear capacity battery. During the nuclear capacity process, the nuclear capacity load can not only have the nuclear capacity resistance but also other nuclear capacity components that can be added as needed to jointly constitute the nuclear capacity load. Since the nuclear capacity components involved in the nuclear capacity load change in real time, the nuclear capacity resistance and the nuclear capacity components are not embodied in Figure 1 The second-type control switch refers to a total switch on the line between the nuclear capacity load and the nuclear capacity battery, which provides a discharge carrier for the nuclear capacity battery by closing the total switch.

[0045] Specifically, when the battery pack is in a non-nuclear capacity state, the control module closes the first-type control switch to realize direct power supply of the battery to the DC load; and when the battery is in a nuclear capacity state, the control module opens the first-type control switch to disconnect the direct connection between the battery and the DC load, and switches the on-off switch on the voltage boosting unit corresponding to the non-nuclear capacity battery to a closed state, so that the non-nuclear capacity battery supplies power to the DC load after being boosted by the voltage boosting unit. At this time, the on-off switch on the voltage boosting unit corresponding to the nuclear capacity battery remains in an open state to ensure that the nuclear capacity battery only discharges to the nuclear capacity load.

[0046] The embodiment of the present application realizes the beneficial effects of online uninterrupted battery capacity by introducing a switching module; the data monitoring module can collect various parameters of the battery all day long, providing data support for intelligent judgment of battery capacity conditions and execution of battery capacity operation, and improving the intelligent level of the system. At the same time, in the battery capacity process, the auxiliary decision module monitors whether the battery capacity process is abnormal by receiving the voltage, resistance and temperature of the battery in real time, and can immediately stop the battery capacity and take corresponding measures when an abnormality occurs, thereby ensuring the reliability of the power distribution terminal. Finally, the system fully considers the green environmental protection requirement when designing the battery capacity load, selects appropriate components for discharge according to the environmental conditions, and realizes a more environmentally friendly and energy-saving battery capacity mode.

[0047] For ease of understanding, Figure 2 The connection relationship among the control module, the data monitoring module and the auxiliary decision module is shown. Specifically, the data collected by the data monitoring module from the battery capacity battery are the voltage value, resistance value and temperature value of the battery capacity battery, and the data collected from the surrounding environment are the brightness value and particle concentration value. The data monitoring module transmits the collected data to the auxiliary decision module in real time, and the auxiliary decision module analyzes the received data and issues relevant control instructions to the control module.

[0048] Optionally, the system further comprises a data monitoring module and an auxiliary decision module, wherein the data monitoring module is connected with the auxiliary decision module and each battery in the battery group; and the auxiliary decision module is connected with the control module.

[0049] The data monitoring module is configured to collect the resistance value, temperature value and voltage value of the target battery capacity battery during the battery capacity process of the target battery capacity battery and transmit them to the auxiliary decision module in real time.

[0050] The auxiliary decision module is configured to analyze the received resistance value, temperature value and voltage value, and send a matched first type of control instruction to the control module according to the analysis result.

[0051] The control module is further configured to switch and control the battery capacity state of the uninterrupted battery capacity system of the battery group according to the received first type of control instruction.

[0052] Optionally, the battery capacity load further comprises a fresh air making component and a dehumidification and heating component, and the fresh air making component and the dehumidification and heating component are connected in parallel with the battery capacity resistor. A third type of control switch is arranged on the parallel branch where the fresh air making component and the dehumidification and heating component are located.

[0053] The fresh air making component is configured to cool the connected target battery capacity battery in the battery capacity state.

[0054] The dehumidification and heating assembly is used for heating the connected target nuclear storage battery in a nuclear storage state.

[0055] The auxiliary decision module is further configured to perform data analysis according to the received temperature value, and send a matched second type of control instruction to the control module according to an analysis result.

[0056] The control module is further configured to perform on-off control on the third control switch in the parallel branch of the fresh air making assembly and / or the dehumidification and heating assembly according to the received second type of control instruction.

[0057] The fresh air making assembly is an air conditioning device, which is used for cooling the nuclear storage battery in the embodiment of the present application. The dehumidification and heating assembly is similar to the fresh air making assembly, but has an opposite function, and is mainly used for heating the nuclear storage battery. In an actual nuclear storage process, the data monitoring module sends a real-time temperature value of the nuclear storage battery to the auxiliary decision module. Through a preset corresponding relationship between the temperature of the nuclear storage battery and a control rule, the auxiliary decision module sends a corresponding control instruction to the control module. That is, the first type of control instruction is for controlling the switching module, and the second type of control instruction is for controlling the connection of the fresh air making assembly and the dehumidification and heating assembly in the nuclear storage load. Correspondingly, the connection of the fresh air making assembly and the dehumidification and heating assembly in the nuclear storage load is realized by controlling the third type of control switch.

[0058] Optionally, the nuclear storage load further includes a lighting assembly and a dust removal assembly, the lighting assembly and the dust removal assembly are connected in parallel with the nuclear storage resistor, and the lighting assembly and the dust removal assembly are respectively provided with the third type of control switch in the parallel branch.

[0059] The lighting assembly is used for providing peripheral lighting for power equipment arranged in an environment.

[0060] The dust removal assembly is used for dust removal and heat dissipation for power equipment arranged in an environment.

[0061] The data monitoring module is further configured to collect a brightness value and a particle concentration value of an environment in which the power equipment is arranged, and send the brightness value and the particle concentration value to the auxiliary decision module.

[0062] The auxiliary decision module is further configured to perform data analysis according to the received brightness value and particle concentration value, and send a matched third type of control instruction to the control module according to an analysis result.

[0063] The control module is further configured to perform on-off control on the third type of control switch in the parallel branch of the lighting assembly and / or the dust removal assembly according to the received third type of control instruction.

[0064] Different from the new air assembly and the dehumidification and heating assembly, the introduction of the lighting assembly and the dust removal assembly does not need to monitor the state of the nuclear capacity storage battery, but determines when the lighting assembly and the dust removal assembly are integrated into the nuclear capacity load through the collection of environmental information by the data monitoring module. Specifically, the lighting assembly is used to provide lighting when the brightness of the environment around the device is too low, without the need for additional lighting of the lighting device, thereby saving resources; the dust removal assembly is used to remove dust when the particle concentration around the device is too high, thereby providing good heat dissipation conditions for the electrical equipment. That is, different from the first type of control instruction and the second type of control instruction, the third type of control instruction is a connection control for the lighting assembly and the dust removal assembly in the nuclear capacity load, and accordingly, the connection control for the lighting assembly and the dust removal assembly in the nuclear capacity load is realized by controlling the third type of control switch, that is, the third type of control switch is a switch on the branch corresponding to each nuclear capacity load under the second type of control switch.

[0065] For the convenience of understanding, Figure 3 For the connection relationship between the nuclear capacity load and the nuclear capacity storage battery, the structural relationship among the nuclear capacity storage battery, the second type of control switch, the third type of control switch and the nuclear capacity load is shown.

[0066] Embodiment two

[0067] Figure 4 A flowchart of a battery pack uninterrupted nuclear capacity method provided by the second embodiment of the present application, the present embodiment can be applicable to the uninterrupted nuclear capacity of any single battery in the battery pack, and the method can be executed by a battery pack uninterrupted nuclear capacity system, which can be configured in a power distribution automation complete tapping box. As shown in the figure, the method comprises the following steps. Figure 4

[0068] S410, by the control module, in the non-nuclear capacity state, control each first type of control switch to be in the closed state, and control each second type of control switch to be in the open state.

[0069] S420, by the control module, in the nuclear capacity state, after controlling each first type of control switch to be in the open state, control the on-off switch of the boost unit in the target switching module matched with the target nuclear capacity storage battery selected as the target nuclear capacity power supply to be in the open state, and control the on-off switches of other boost units to be in the connected state; control the target second type of control switch on the connection branch between the nuclear capacity load and the target battery selected as the target nuclear capacity power supply to be in the closed state.

[0070] Optionally, the method can further comprise the following steps.

[0071] In the nuclear capacity state, the data monitoring module collects the internal resistance value, the temperature value and the voltage value of the target nuclear capacity storage battery and sends them to the auxiliary decision-making module in real time.

[0072] ​The auxiliary decision module performs data analysis according to the received internal resistance value, temperature value and voltage value, and sends a matched first-type control instruction to the control module according to an analysis result.

[0073] The control module performs switching control on the capacity of the battery pack according to the received first-type control instruction.

[0074] Further, the auxiliary decision module performs data analysis according to the received internal resistance value, temperature value and voltage value, and sends a matched first-type control instruction to the control module according to an analysis result, including at least one of the following:

[0075] The auxiliary decision module sends a first-type control instruction for stopping the capacity to the control module when determining that the voltage value is not in a standard floating interval.

[0076] The auxiliary decision module sends a first-type control instruction for stopping the capacity to the control module when determining that the voltage value is not in a standard floating interval, and records a capacity stopping time; when a first time length is reached from the capacity stopping time, the auxiliary decision module sends a first-type control instruction for starting target capacity battery constant charging of a direct current load to the control module.

[0077] The auxiliary decision module sends a first-type control instruction for stopping the capacity to the control module when determining that the temperature value exceeds a standard temperature interval, and records a capacity stopping time; when a second time length is reached from the capacity stopping time, the auxiliary decision module sends a first-type control instruction for re-capacity of the target capacity battery to the control module.

[0078] In the embodiment of the application, the internal resistance value, temperature value and voltage value are collected to determine whether the operation of the capacity battery is abnormal. Specifically, a corresponding relationship between a theoretical battery capacity value and a battery voltage value can be obtained according to a pre-constructed relationship curve between the battery capacity and the voltage, and the standard floating interval is a pre-set difference value allowed to float between an actual voltage and a theoretical voltage. When the actual voltage change value of the capacity battery is not in the standard floating interval, it indicates that the voltage value fluctuates greatly and is abnormal. At this time, the auxiliary decision module sends an alarm information to a remote administrator end while sending a capacity stopping instruction to the control module, and does not perform a capacity operation on the capacity battery until the abnormality is eliminated.

[0079] In one specific example, if the nuclear storage battery is 12V38Ah, the standard resistance threshold is set to 8mΩ, and the first time length is set to 5 minutes, when the battery resistance exceeds 8mΩ, the stop nuclear storage instruction is sent, when the stop nuclear storage time reaches 5 minutes, the on-off switch on the unidirectional DC / DC step-down unit corresponding to the nuclear storage battery is closed, and the second type of control switch is opened, so that the nuclear storage battery resumes power supply to the DC load.

[0080] According to the national standard, the standard temperature interval is generally [-20℃-60℃], when the internal resistance temperature of the nuclear storage battery exceeds 60℃, the nuclear storage needs to be suspended, that is, the stop nuclear storage instruction is sent and the timing is started, the preset second time length is the cooling time of the nuclear storage battery, and after the cooling is completed, the nuclear storage battery is restarted.

[0081] Optionally, the method can further include:

[0082] Through the auxiliary decision module, data analysis is performed according to the received temperature value, and the matched second type of control instruction is sent to the control module according to the analysis result;

[0083] Through the control module, the third type of control switch on the parallel branch of the fresh air making assembly and / or the dehumidification and heating assembly is opened and closed according to the received second type of control instruction.

[0084] Further, through the auxiliary decision module, data analysis is performed according to the received temperature value, and the matched second type of control instruction is sent to the control module according to the analysis result, which can specifically include:

[0085] Through the auxiliary decision module, when it is determined that the battery temperature exceeds the preset high temperature threshold, the second type of control instruction for opening the third type of control switch on the parallel branch of the fresh air making assembly is sent to the control module;

[0086] After sending the second type of control instruction for opening the third type of control switch on the parallel branch of the fresh air making assembly, when it is determined that the battery temperature is lower than the preset high temperature threshold, the second type of control instruction for closing the third type of control switch on the parallel branch of the fresh air making assembly is sent to the control module;

[0087] Through the auxiliary decision module, when it is determined that the battery temperature is lower than the preset low temperature threshold, the second type of control instruction for opening the third type of control switch on the parallel branch of the dehumidification and heating assembly is sent to the control module;

[0088] When the second type of control instruction for opening the third type of control switch on the parallel path of the dehumidification and heating assembly is sent, and it is determined that the battery temperature is higher than the preset low temperature threshold, the second type of control instruction for closing the third type of control switch on the parallel path of the dehumidification and heating assembly is sent to the control module;

[0089] The preset high temperature threshold and the preset low temperature threshold are both in a standard temperature range.

[0090] In one specific example, the preset high temperature threshold can be set to 50 DEG C, and the low temperature threshold can be set to 10 DEG C. When the battery temperature reaches 50 DEG C, the fresh air making assembly is incorporated into the nuclear capacity load, and when the battery temperature is lower than 50 DEG C, the circuit connection between the fresh air making assembly and the nuclear capacity battery is disconnected. Similarly, when the battery temperature is lower than 10 DEG C, the dehumidification and heating assembly is incorporated into the nuclear capacity load, and when the battery temperature is higher than 10 DEG C, the circuit connection between the dehumidification and heating assembly and the nuclear capacity battery is disconnected. It should be noted that the nuclear capacity resistance and the nuclear capacity battery are always in a connected state during the entire nuclear capacity process.

[0091] Optionally, the method can further include:

[0092] The brightness value and the particle concentration value of the environment where the power equipment is located are collected by the data monitoring module and sent to the auxiliary decision-making module;

[0093] The auxiliary decision-making module performs data analysis according to the received brightness value and particle concentration value, and sends a matched third type of control instruction to the control module according to the analysis result;

[0094] The control module controls the opening and closing of the third type of control switch on the parallel branch of the lighting assembly and / or the dust removal assembly according to the received third type of control instruction;

[0095] The auxiliary decision-making module performs data analysis according to the received brightness value and particle concentration value, and sends a matched third type of control instruction to the control module according to the analysis result further includes:

[0096] When the brightness value of the environment where the power equipment is located is determined to be lower than the preset brightness threshold, the auxiliary decision-making module sends a third type of control instruction for opening the third type of control switch on the parallel branch of the lighting assembly to the control module;

[0097] When the third type of control instruction for opening the third type of control switch on the parallel branch of the lighting assembly is sent, and it is determined that the brightness value of the environment where the power equipment is located is higher than the preset brightness threshold, the auxiliary decision-making module sends a third type of control instruction for closing the third type of control switch on the parallel branch of the lighting assembly to the control module;

[0098] When the auxiliary decision module determines that the particle concentration value of the environment where the power equipment is located is higher than the preset particle concentration threshold, the auxiliary decision module sends a third type of control instruction for turning on the third type of control switch on the parallel branch of the dust removal assembly to the control module;

[0099] When the auxiliary decision module determines that the particle concentration value of the environment where the power equipment is located is lower than the preset particle concentration threshold after sending the third type of control instruction for turning on the third type of control switch on the parallel branch of the dust removal assembly, the auxiliary decision module sends a third type of control instruction for turning off the third type of control switch on the parallel branch of the dust removal assembly to the control module.

[0100] In addition, the embodiment of the present application creatively proposes green utilization of nuclear capacity discharge resources, that is, under the premise of meeting the nuclear capacity requirement, the lighting assembly and the dust removal assembly are selectively incorporated by considering the brightness and particle concentration of the surrounding environment, so as to realize lighting and heat dissipation for the power equipment, and the energy waste and environmental pollution problems caused by the resistance discharge method in the traditional way are avoided.

[0101] The embodiment of the present application proposes a new battery pack uninterrupted nuclear capacity method, specifically, the data acquisition module can judge whether the nuclear capacity process is abnormal by acquiring data in the nuclear capacity battery, and green nuclear capacity can be realized by acquiring surrounding environment data. At the same time, the switching module, the control module, the data detection module and the auxiliary decision module are described in detail, and how to cooperate between different modules is described in detail; the flexible operation of the battery pack uninterrupted nuclear capacity system is realized by realizing the linkage between the modules, which provides strong technical support for improving the reliability and efficiency of the power distribution terminal.
