Description

Technical Field

[0001] The utility model relates to the technical field of energy storage management, in particular to an energy storage management system. Background Art

[0002] At present, in order to stabilize the output power fluctuations in new energy power stations, wind power stations or solar power stations, more and more power plants are beginning to be equipped with independent energy storage systems, and independent energy storage power stations that rely on reselling electricity are gradually emerging. Among them, microgrids, as the core component of independent energy storage power stations, usually need to be equipped with an energy storage management system to ensure the continuity and stability of the energy storage system operation.

[0003] In the prior art, the energy storage management system is usually powered directly by an external power supply. Once the external power supply disappears, the energy storage management system directly exits operation, seriously affecting the normal operation of the energy storage management system. In some cases, when the external power supply is disconnected, the energy storage device in the energy storage management system itself is powered by the battery end through manual or other control methods to continue to supply power to ensure the normal operation of the system. However, this power supply method cannot be switched in time after the external power supply is restored. In the long run, it will increase the self-discharge of the battery cell at the battery end, causing the battery voltage to drop. In addition, due to the inconsistency inside the battery cell, the amplitude of the battery voltage drop is inconsistent, which in turn leads to an increase in the inconsistency of the battery cells of the entire energy storage system. Both of the above power supply methods will affect the stability and reliability of the overall operation of the energy storage system. Utility Model Content

When the uninterruptible power supply module fails or fails, the system can automatically switch to the battery module to obtain power, ensuring the stability and reliability of the system operation, avoiding system data loss or equipment damage due to power interruption, and the switching of power supply between the two modules can also effectively reduce the self-discharge of the battery cells in the battery module, and effectively reduce the inconsistency of the battery cells; the battery monitoring module in the energy storage management system can monitor and manage the battery module in real time, discover battery problems in time, protect the health of the battery and extend the service life of the battery. The energy storage management system provided by the present application can achieve uninterrupted power supply, ensure the stability and reliability of the system operation, improve the ability to handle faults, achieve efficient energy utilization, and reduce energy waste.

[0048] Specifically, the black start control module used in the present application is an electronic device with a switching function and a control function. Among them, the switching function can be realized by a switching device such as a relay, an electronic switch, a triode, a MOS tube, etc., and the control function can be realized by a control device such as a single chip microcomputer, an FPGA, a PLC, etc. In this embodiment, the switching device can be controlled by a program module set in the control device, and the control program of the switching device can be realized by a program module in the prior art. It can be understood that the circuit function realized in this embodiment is mainly realized by the circuit connection relationship between each electronic device. For example, in the present application, the black start control module is connected to the uninterruptible power supply module and the battery module respectively, and the power supply status of the uninterruptible power supply module is detected, and the control device is used to control the operation of the switch device to connect the uninterruptible power supply module or the battery module for power supply. Specifically, the control end of the black start control module is connected to the output end of the uninterruptible power supply module and the output end of the battery module respectively. When the black start control module detects that the uninterruptible power supply module has a transient current, the black start control module limits the flow of the transient current, while effectively protecting the components in the circuit, and starts the circuit in an orderly manner, and uses the uninterruptible power supply module for power supply. When the black start control module does not detect that the uninterruptible power supply module has a transient current, it controls the battery module to supply power, thereby realizing the switching between the uninterruptible power supply module and the battery module, and playing the role of monitoring the power input and output to ensure the smooth and normal operation of the system. The switch switching functions are all possessed by the control modules commonly used in the prior art. At the same time, the DC / DC direct current conversion module provided in the present application is also a common power electronic device, which is used to convert direct current power from one voltage level to another voltage level to meet the voltage requirements of specific equipment or systems; in the present application, through the DC / DC direct current conversion module, the system can convert the output voltage provided by the uninterruptible power supply module or battery module into an adaptive voltage to adapt to the voltage requirements of different equipment and provide a stable power supply.

[0049] Specifically, in the above embodiment, the black start control module includes a black start unit, a first control switch K1 and a second control switch K2. Figure 2As shown, the output end of the uninterruptible power supply module is connected to the first input end of the black start unit through the first control switch K1, the output end of the battery module is connected to the second input end of the black start unit through the second control switch K2, and the output end of the black start unit is connected to the DC / DC direct current conversion module; when the black start control module detects that the uninterruptible power supply module has an output voltage, the first control switch K1 is controlled to be in a closed state, and the second control switch K2 is controlled to be in a disconnected state, and the uninterruptible power supply module is connected to the black start unit; when the black start control module detects that the uninterruptible power supply module has no output voltage, the second control switch K2 is controlled to be in a closed state, and the first control switch K1 is controlled to be in a disconnected state, and the battery module is connected to the black start unit.

[0050] In this embodiment, the black start unit in the black start control module is used to realize the core control function of the module, and specifically, the first control switch K1 and the second control switch K2 are set to respectively realize the access of the uninterruptible power supply module and the battery module, thereby realizing effective control of the power switching process. The structure of the control switch is simple and easy to operate, which can ensure that when the uninterruptible power supply module fails or the output voltage is interrupted, it can switch to the battery module in time to ensure the continuous power supply of the equipment and improve the reliability of the system. In this application, the black start control module is switched according to the power supply state of the uninterruptible power supply module. When the black start control module detects that the uninterruptible power supply module has an output voltage, the black start control unit controls the first control switch K1 to close, and the circuit will be directly connected to the uninterruptible power supply module to realize the power supply function; when the black start control module detects that the uninterruptible power supply module does not have an output voltage, it means that the uninterruptible power supply module fails or the output voltage is interrupted, and the black start control unit controls the second control switch K2 to close, and the circuit will switch to the battery module to ensure continuous power supply. The automatic switching of the black start control module can reduce manual intervention and improve the reliability and stability of the system. In addition, the setting of the black start control module allows the system to choose to use an uninterruptible power supply module or a battery module for power supply according to actual needs. For example, under normal working conditions, the uninterruptible power supply module can be used for power supply first to provide a more stable power supply. When the uninterruptible power supply module fails or the output is interrupted, it can be switched to the battery module in real time to ensure the continued operation of the equipment. The setting of the black start control module enables the system to select and switch power supplies as needed to adapt to different operating conditions. Furthermore, the present application connects the black start unit to the DC / DC direct current conversion module so that the black start control module can be used in combination with other components to achieve more functions, such as adjustment and stabilization of input and output voltages, load distribution and management, etc., thereby making the system highly extensible.

[0051] Furthermore, the black start control module also includes an AC / DC alternating current and direct current conversion unit, a DC / DC direct current conversion unit, a first indicator light L1 and a second indicator light L2, wherein the output end of the uninterruptible power supply module is connected to the input end of the AC / DC alternating current and direct current conversion unit, the output end of the AC / DC alternating current and direct current conversion unit is connected to the first control switch K1, a first indicator light L1 is also connected between the first control switch K1 and the first input end of the black start unit, and when the first control switch K1 is in a closed state, the first indicator light L1 lights up, the output end of the battery module is connected to the input end of the DC / DC alternating current and direct current conversion unit, the output end of the DC / DC alternating current and direct current conversion unit is connected to the second control switch K2, a second indicator light L2 is also connected between the second control switch K2 and the second input end of the black start unit, and when the second control switch K2 is in a closed state, the second indicator light L2 lights up.

[0052] In this embodiment, an AC / DC conversion unit and a DC / DC conversion unit are provided in the black start control module, which are respectively connected to the uninterruptible power supply module and the battery module, and are used to receive the output voltages of the two modules and convert them into stable direct current required by the black start control unit; and the first indicator light L1 and the second indicator light L2 are respectively connected to the first control switch K1 and the second control switch K2 of the black start control unit, and are used to indicate the status of the corresponding control switches. When one of the control switches is in a closed state, the correspondingly connected indicator light is on, so that the user can intuitively distinguish whether the uninterruptible power supply module or the battery module is supplying power.

[0053] Specific as Figure 3 As shown, the uninterruptible power supply module is used to output 220V AC voltage to the AC / DC conversion unit. The AC / DC conversion unit specifically uses the AC88-264 / DC24V model, which is used to convert the output voltage of the uninterruptible power supply module into a 24V DC voltage for output. The output end of the AC / DC conversion unit is connected to a first control switch K1 and a first indicator light L1. When the battery module is supplying power, the first control switch K1 is closed and the first indicator light L1 is on; both ends of the battery bus of the battery module are connected to the DC / DC conversion unit. The DC / DC conversion unit specifically uses the DC200-1500 / DC24V model, which is used to convert the output voltage of the battery module into a 24V DC voltage for output. The output end of the DC / DC conversion unit is connected to a second control switch K2 and a second indicator light L2. When the battery module is supplying power, the second control switch K2 is closed and the second indicator light L2 is on; and switches can be set between the AC / DC conversion unit and the uninterruptible power supply module, and between the DC / DC conversion unit and the battery module for further control.

[0054] Specifically, in the above embodiment, if Figure 4 As shown, the input end of the battery module is connected to the third control end of the black start control module. When the black start control module detects that the uninterruptible power supply module has an output voltage, the first control end of the black start control module is also connected to the third control end, and the uninterruptible power supply module supplies power to the battery module through the black start control module.

[0055] In this embodiment, when the output voltage of the uninterruptible power supply module is normal, the black start control module connects the battery module with the uninterruptible power supply module, and uses the uninterruptible power supply module to charge the battery module, so that the battery module has sufficient power and can be used as a backup power supply at any time, and provide continuous power supply to key equipment or systems in the event of a main power failure or interruption, so as to maintain stable operation of the system. In order to enable the battery module to stably receive the power supply of the uninterruptible power supply module, a charging controller and a charging circuit need to be equipped at the input end of the battery module. The charging controller is responsible for controlling the charging current of the battery module and managing the charging state to ensure that the charging process is safe and effective. The charging circuit usually includes components such as a current sensor, a voltage regulator, and a charging switch to ensure that the charging current and voltage are within a controllable range. In addition, during the charging process, a charging management algorithm needs to be used to control and monitor the charging process. At the same time, in order to ensure the safety of the charging process, a charging protection mechanism needs to be used, such as overcurrent protection, overvoltage protection, overtemperature protection, etc., to effectively avoid overcharging, failures during the charging process, and possible safety hazards.

[0056] Specifically, in the above embodiment, the energy storage management system further includes an AC / DC conversion module, such as Figure 5 As shown, the input end of the AC / DC conversion module is connected to an AC power source, and the output end of the AC / DC conversion module is connected to the input end of the uninterruptible power supply module. The AC / DC conversion module converts the AC power output by the AC power source into DC power and then supplies power to the uninterruptible power supply module.

[0057] In this embodiment, AC power supply is a common form of public power supply network, and in some cases, such as normal power supply and charging of battery modules, the uninterruptible power supply module usually requires DC power to work normally, so an AC / DC conversion module can be provided between the AC power supply and the uninterruptible power supply module to convert the input AC power into DC power to meet the power supply requirements of the uninterruptible power supply module, and the AC / DC conversion module has a stable conversion capability, which can convert the current output by the AC power supply into DC power and maintain a certain stability and reliability, which helps to provide stable power supply to the uninterruptible power supply module and ensure the stable operation of the system. At the same time, it can also improve the utilization rate of power, reduce energy loss, and provide more efficient power conversion.

[0058] Specifically, in the above embodiment, if Figure 6 As shown, the data acquisition end of the battery monitoring module is connected to the first data end of the black start control module, the data transmission end of the uninterruptible power supply module is connected to the second data end of the black start control module, the data transmission end of the battery module is connected to the third data end of the black start control module, and the first data end of the black start control module is respectively connected to the second data end of the black start control module and the third data end of the black start control module; the data acquisition end of the battery monitoring module is respectively connected to the data transmission end of the battery module and the data transmission end of the uninterruptible power supply module through the black start control module to collect the operating data of the battery module and the uninterruptible power supply module.

[0059] In this embodiment, the battery monitoring module is connected to the uninterruptible power supply module and the battery module respectively through the black start control module, and further collects the operation data of the uninterruptible power supply module and the battery module, so as to achieve the effect of real-time monitoring of the battery status, power and other related parameters, and then realize the integration and monitoring of data, which is helpful to integrate the data from the battery module and the uninterruptible power supply module, obtain the comprehensive operation status information of the system, and perform corresponding control and protection. At the same time, it can also timely discover whether there are problems in the operation of the two modules, and timely switch the power supply module to ensure the reliability and safety of the system operation.

[0060] Furthermore, a fault detection unit is provided in the battery monitoring module. The fault detection unit is used to determine the fault point and cut off the circuit connection of the fault point when abnormal operation data is detected, and generate alarm information at the same time.

[0061] In this embodiment, the process of fault detection by the fault detection unit specifically includes comparing the collected operating data of the battery module and the uninterruptible power supply module based on preset standard data, respectively, to obtain the comparison results of the respective modules. When the comparison result indicates that the operating data of any of the two modules is abnormal, the fault detection unit determines the fault point based on the operating data and cuts off the circuit connection of the fault point, and generates an alarm message to promptly remind the staff. Some functions of the fault detection unit in the present application can be implemented by using program modules in the prior art. For example, conventional data processing processes such as data collection and data comparison can be implemented by program modules in the prior art. It can be understood that the fault detection function described in this embodiment is mainly realized by relying on the connection relationship between the various circuit modules in the circuit. For example, in the present application, the fault detection unit can be specifically used to monitor the acquired operating data of the battery module and the uninterruptible power supply module, and locate the fault point when the operating data is detected to be abnormal, quickly identify the fault in the battery monitoring system, and accurately determine the source of the problem. Once the fault point is determined, the fault detection unit can cut off the circuit connection of the fault point to prevent the fault from spreading or continuing to affect the operation of other parts. By cutting off the fault circuit, potential dangers and system damage can be avoided. At the same time, after detecting the abnormality and cutting off the fault circuit connection, the fault detection unit can also generate an alarm message, which can promptly remind the operator or relevant staff to pay attention to the existence of the fault and take repair measures in time to reduce downtime and avoid further losses. This function can be set in the on-board charger. When the output of the battery monitoring module is accidentally short-circuited, the battery monitoring module automatically shuts down the output and can work normally after the fault is manually eliminated.

[0062] Specifically, in the above embodiment, a temperature detection unit is provided in the battery monitoring module, and the temperature detection unit is used to control the battery monitoring module to shut down when it detects that the real-time temperature of the battery monitoring module reaches a preset temperature, and to control the battery monitoring module to start when the real-time temperature of the battery monitoring module is lower than the preset temperature.

[0063] In this embodiment, part of the temperature detection function of the temperature detection unit can be implemented by using the program modules in the prior art. For example, conventional data processing processes such as temperature data acquisition and temperature data comparison can be implemented by program modules in the prior art. It can be understood that the temperature detection function described in this embodiment mainly depends on the connection relationship between the various circuit modules in the circuit. For example, the temperature detection unit can monitor the real-time temperature of the battery monitoring module, and by setting a preset temperature value, once the real-time temperature reaches the preset temperature, the temperature detection unit will control the battery monitoring module to shut down to avoid damage to the device or unstable operation due to excessive temperature.

[0064] In another embodiment, the preset temperature can be specifically divided into a first preset temperature and a second preset temperature, wherein the second preset temperature is higher than the first preset temperature. Specifically, when the temperature detection unit detects that the real-time temperature of the battery monitoring module reaches the first preset temperature, the output current of the DC / DC direct current conversion module is reduced until the real-time temperature of the battery monitoring module is lower than the first preset temperature, and the output current intensity is restored. When the temperature detection unit detects that the real-time temperature of the battery monitoring module reaches the second preset temperature, the battery monitoring module is controlled to shut down, and when the real-time temperature of the battery monitoring module is lower than the first preset temperature, the battery monitoring module is controlled to start. In this embodiment, the preset temperatures are finely divided for further distinction. Regardless of which embodiment is adopted, the ultimate effect to be achieved is that by real-time detection and control of the temperature of the battery monitoring module, faults and damage caused by excessive temperature can be prevented, and under temperature control, the life of the battery monitoring module can also be extended.

[0065] Specifically, in the above embodiment, an EMI circuit is provided at the input end of the DC / DC direct current conversion module, and the EMI circuit is used to filter and isolate the electrical signal received by the DC / DC direct current conversion module.

[0066] Among them, the EMI (Electromagnetic Interference) circuit is a circuit used to suppress and filter electromagnetic interference. The EMI circuit reduces the propagation and impact of electromagnetic interference by adding a series of electronic components and filters at the input or output of the electronic device. The added components and filters are used to filter out high-frequency noise, stray signals and other unnecessary electromagnetic radiation, thereby improving the electromagnetic compatibility of the equipment. EMI circuits usually include filters, isolators, anti-jitter capacitors, shielding materials and shielding covers. The filter is used to filter high-frequency noise and stray signals, and only allows signals in a specific frequency range to pass; the isolator is used to isolate electromagnetic interference signals from different signal sources to avoid mutual interference between different signals; the anti-jitter capacitor is used to reduce sudden current and voltage changes caused by switching power supplies, etc., to avoid electromagnetic radiation interference; the shielding material and shielding cover are used to shield electromagnetic radiation and interference signals to prevent them from leaking from the inside of the device or entering from the outside.

[0067] In this embodiment, by setting an EMI circuit at the input end of the DC / DC direct current conversion module, noise and interference signals can be effectively filtered out, and the propagation of electromagnetic interference can be reduced, thereby protecting the normal operation of other electronic devices. Specifically, the EMI circuit can filter out unnecessary high-frequency noise and stray signals, ensuring that the signal quality input to the DC / DC direct current conversion module is purer, which helps to improve the stability of the DC / DC direct current conversion module and reduce electromagnetic interference at the output end; through the isolation effect of the EMI circuit, interference signals from the external environment can be effectively isolated, and the DC / DC direct current conversion module can be protected from interference sources; and the setting of the EMI circuit can also effectively reduce the radiation and reception of interference signals, so that the system meets the electromagnetic compatibility (EMC) standards and ensures normal operation in an electromagnetic environment.

[0068] Specifically, in the above embodiment, the energy storage management system is disposed in a closed casing, and a water cooling channel is disposed in the closed casing, and the water cooling channel is used to dissipate heat for the energy storage management system.

[0069] In this embodiment, since the energy storage management system generates a certain amount of heat during operation, a water cooling channel is provided in the closed casing to effectively dissipate the heat by circulating cooling water, so as to keep the temperature of the system always within an acceptable range, thereby ensuring the long-term stable operation of the system and reducing the failure and damage of components and electronic equipment in the system caused by high temperature; and compared with traditional heat dissipation methods such as fans, water cooling channels can provide more efficient and quieter heat dissipation effects, thereby reducing the noise level of the energy storage management system; at the same time, the water cooling channel is provided in the closed casing to effectively utilize the space, without the need to add additional fans or other heat dissipation equipment, so that the overall structure of the system is more compact and saves physical space.
