[0030] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the present utility model will be briefly introduced below in conjunction with the accompanying drawings and descriptions of the embodiments or the prior art. Obviously, the following description of the structure of the accompanying drawings is only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort. It should be noted that the description of these embodiments is used to help understand this utility model, but does not constitute a limitation on this utility model.
[0031] Example 1:
[0032] This embodiment discloses an energy storage lighting control system, such as Figure 1 As shown, the energy storage lighting control system includes a main control module, a first power conversion module, an energy storage module, a boost drive module, a second power conversion module, and a lighting module. The lighting module has two power input terminals. The power input terminals of both the first and second power conversion modules are connected to the external power grid. The power output terminal of the first power conversion module is connected to one power input terminal of the lighting module via the energy storage module and the boost drive module, and the power output terminal of the second power conversion module is connected to the other power input terminal of the lighting module. The controlled terminals of the first power conversion module, the energy storage module, the boost drive module, and the second power conversion module are all connected to the main control module.
[0033] During preset peak electricity consumption periods, the main control module controls the boost drive module to operate, so that the boost drive module performs DC (Direct Current) / DC boost conversion on the power supply voltage of the energy storage module, and then provides power support to the lighting module;
[0034] During preset off-peak electricity consumption periods, the main control module controls the second power conversion module to operate, so that the second power conversion module performs AC (Alternating Current) / DC conversion on the power supply voltage from the external power grid and then provides power support to the lighting module; at the same time, it controls the first power conversion module to operate, so that the first power conversion module performs AC / DC conversion on the power supply voltage from the external power grid and then charges the energy storage module.
[0035] Specifically, in this embodiment, the peak electricity consumption period is set to 18:00–24:00 daily (18:00 is the lighting time, and 24:00 is the battery charging time for the lighting; the charging time is controllable). During the peak electricity consumption period, power is preferentially supplied to the lighting module through the energy storage module. Avoiding peak electricity prices can reduce the peak load on the power grid, achieving peak shaving and valley filling for energy conservation and environmental protection. The off-peak electricity consumption period is set to 00:00–7:00 daily. During the off-peak electricity consumption period, power is preferentially supplied to the lighting module through the external power grid to achieve lighting, and the energy storage module is charged through the external power grid. Utilizing off-peak charging can reduce electricity costs, achieving peak shaving and valley filling for energy conservation and environmental protection.
[0036] Furthermore, in this embodiment, during preset peak electricity consumption periods, the energy storage module undergoes anomaly detection and processing. When the energy storage module is in an abnormal state, the second power conversion module is controlled to operate, enabling it to perform AC / DC conversion of the external grid's supply voltage before providing power to the lighting module. Specifically, when the energy storage module's stored energy is below 10% or the battery pack used for energy storage malfunctions, the system automatically switches to mains lighting, supplying power to the lighting module through the external grid, and automatically prevents charging of the energy storage module to ensure lighting stability.
[0037] In this embodiment, as Figure 2 As shown, the main control module uses the GD32F303RCT6 main controller U38 and its peripheral circuits. The GD32F303RCT6 main controller U38 is a high-performance microcontroller based on the ARM Cortex-M3 core. It has a built-in digital-to-analog converter that can convert digital signals into analog signals to drive various analog circuits or interfaces. Its operating efficiency is close to that of the STM32F3 series, but with lower power consumption. It supports dynamic voltage regulation and has rich peripheral interfaces, making it suitable for industrial control and communication scenarios.
[0038] Specifically, in this embodiment, the peripheral circuit of the main controller U38 includes a running indicator module, a communication module, a program burning module, a debugging module, a storage module, and a clock module.
[0039] The operation indicator module includes an LED D5 and a resistor R41 connected to the main controller U38. The LED D5 illuminates during operation of the main controller module to indicate operation. The communication module includes a communication port U45 that can be connected to the communication terminal of the energy storage module. It is isolated from the main controller U38 by a π122U31 type digital isolation chip U44 to protect the main controller U38. The programming module uses a programming port J7, and the debugging module uses a debugging serial port J9, allowing users to program and debug the main controller U38.
[0040] In this embodiment, the energy storage module includes a battery pack, a battery monitoring module, a battery management module, and a battery voltage conversion module. The battery pack is connected to the battery management module through the battery monitoring module. The battery pack is also connected to the power input terminal of the battery voltage conversion module, and the power output terminal of the battery voltage conversion module is the output terminal of the energy storage module.
[0041] like Figure 3 As shown, the battery monitoring module uses a BQ7693003DBT battery monitor U4 and its peripheral circuits. The battery monitoring module is responsible for directly interacting with the analog signals of the battery pack to measure the voltage of a single cell in the battery pack (typically with an accuracy of ±1mV), measure the charging and discharging current through an external shunt resistor or Hall sensor, monitor the cell temperature of the battery pack through a thermistor, and achieve voltage balance between cells through resistive discharge.
[0042] like Figure 4 As shown, the battery management module uses a GD32F310F8P6TR microcontroller U5 and its peripheral circuitry. The peripheral circuitry of the microcontroller U5 includes a temperature compensation module, communication port J2, Bluetooth port J3, and programming port J4. This model of microcontroller U5 offers the best cost-performance ratio in terms of enhanced processing power, reduced power consumption, and peripheral integration, meeting the needs of the digital signal control market that requires efficient and easy-to-use combinations of control and signal processing functions. During implementation, the microcontroller U5 reads the battery status information from the battery monitoring module and sends this information to the main control module via communication port J2, enabling the main control module to remotely monitor and manage the energy storage module. In this embodiment, the battery management module reads the raw data collected by the battery monitoring module and can calculate the SOC (State of Charge, also called remaining capacity) and assess the SOH (State of Health) of the battery pack, thereby providing fault protection for the battery pack under overvoltage (OV), undervoltage (UV), overcurrent (OC), short circuit (SC), and abnormal temperature conditions.
[0043] like Figure 5 The circuit diagram shown is of the battery voltage conversion module. It adopts the HXL1509-3.3 DC / DC step-down converter, which helps to save circuit board space and has an external shutdown function. It can enter standby mode through logic level control.
[0044] In this embodiment, the battery monitoring module can periodically scan multiple channels for synchronous sampling, supporting simultaneous acquisition of multiple voltage / current signals (4 or more cells), avoiding measurement error current caused by time difference (typical period 1s~100ms). It also monitors temperature through an integrated temperature sensor to prevent thermal runaway. During implementation, the data collected by the battery monitoring module is sent to the battery management module, which runs the SOC / SOH algorithm (ampere-hour integration method) to estimate the SOC. If the SOC is unbalanced, the passive balancing function of the battery monitoring module can be activated to balance the cell voltage through energy-consuming resistors. By setting a minimum SOC threshold to prevent overcharging / over-discharging, the battery can achieve adaptive charging and discharging, thus meeting the development needs of smart cities.
[0045] After a long period of technical demonstration and project operation testing, the design for road peak shaving and valley filling energy storage lighting has multiple charging modes for batteries. When the battery is at low voltage, a constant voltage charging mode is used. When a single battery cell (the battery pack uses 8 single cells connected in series) reaches 3V, a constant current charging mode is used. When the voltage reaches 90% of the full charging voltage, a float charging mode is used. This does not affect the battery's charging and discharging performance and lifespan, thus ensuring lighting in important areas such as tunnels, urban traffic, and bridges.
[0046] In this embodiment, the battery pack used for peak shaving and valley filling energy storage lighting uses lithium iron phosphate cells in series, which has an extremely high safety factor, supports high power discharge and a wider operating temperature range, is highly safe, has a long service life, low raw material cost (does not contain any heavy metals or rare metals), charges quickly and has a wide operating temperature range (-15℃ to +55℃).
[0047] In this embodiment, as Figure 6As shown, the boost drive module is composed of a Hi5000 constant current driver U48. It should be noted that the Hi5000 constant current driver U48 is a wide dimming ratio flicker-free dimming LED constant current driver with a simple external circuit. It achieves high-precision constant current performance, with output current accuracy ≤±3%, load regulation <±0.5%, and stable power supply output. It can meet the application requirements of wide input and output voltages, providing flicker-free dimming throughout the entire range. The boost constant current driver module supports buck, boost, and buck-boost topologies, and is suitable for LED constant current lighting applications with an input voltage range of 6.5-75V. It features deep dimming depth, good low-brightness load regulation and consistency, and also has undervoltage protection, temperature protection, reverse connection protection, and mains power switching functions.
[0048] In this embodiment, as Figure 7 As shown, the energy storage lighting control system further includes a lighting brightness adjustment module. The controlled terminal of the lighting brightness adjustment module is connected to the main control module. The power input terminal of the lighting brightness adjustment module is connected to the power output terminal of the boost drive module and / or the power output terminal of the second power conversion module. The power output terminal of the lighting brightness adjustment module is connected to the lighting module. Specifically, in this embodiment, a light source interface CN4 for installing the lighting module is provided. The lighting brightness adjustment module includes a GP8101-F50-N-SW type voltage converter U41. Pin 3 of the voltage converter U41 is connected to the main control module through resistor R76. Pin 4 is connected to the output voltage of the boost drive module and / or the second power conversion module. Pin 5 is grounded. Pin 6 is connected to the power input pin of the light source interface CN4. Pin 6 is also grounded through capacitor C69 and TVS diode D26. Pin 7 is grounded through resistor R80 and capacitor C68. Pin 8 is connected to the junction of resistor R80 and capacitor C68. The GP8101-F50-N-SW voltage converter U41 has built-in filtering and driving circuits, providing stable output and is suitable for scenarios requiring analog voltage control, such as lighting dimming, as described in this embodiment.
[0049] like Figure 7 As shown, the energy storage lighting control system also includes a backup power module, which includes a backup battery interface CN2 connected to the light source interface CN4 and a backup battery charging control module. The controlled end of the backup battery charging control module is connected to the main control module. The main control module is used to charge the backup battery connected to the backup battery interface CN2 by controlling the backup battery charging control module.
[0050] In this embodiment, as Figure 8As shown, the energy storage lighting control system further includes an energy storage discharge drive module. The controlled terminal of the energy storage discharge drive module is connected to the main control module, the power input terminal of the energy storage discharge drive module is connected to the power output terminal of the energy storage module, and the power output terminal of the energy storage discharge drive module is connected to the second power conversion module. In this embodiment, the energy storage discharge drive module includes a transistor Q16 and a P-type MOSFET Q6. The base of transistor Q16 is connected to the main control module through a resistor R58, the emitter of transistor Q16 is grounded, the collector of transistor Q16 is connected to the gate of P-type MOSFET Q6 through a resistor R57, the drain of P-type MOSFET Q6 is connected to the power output terminal of the energy storage module, the source of P-type MOSFET Q6 is connected to the gate of P-type MOSFET Q6 through a resistor R59 and a TVS diode D9, and the source of P-type MOSFET Q6 is the power output terminal of the energy storage discharge drive module connected to the second power conversion module. The main control module can control the power supply to the energy storage module and the second power conversion module through the energy storage discharge drive module, thereby controlling the power supply to the lighting module.
[0051] In this embodiment, as Figure 9As shown, the energy storage lighting control system further includes a power grid data acquisition module and an isolation module. The signal acquisition terminal of the power grid data acquisition module is connected to the external power grid, and the signal output terminal of the power grid data acquisition module is connected to the main control module through the isolation module. In this embodiment, the power grid data acquisition module uses the BL0942 type energy metering chip U50 and its peripheral circuits. The energy metering chip U50 has a built-in clock and requires no calibration, making it suitable for applications such as single-phase multi-functional energy meters, smart sockets, and smart home appliances. It has a high cost-performance ratio. At the same time, the energy metering chip U50 integrates two high-precision Sigma-Delta ADCs, analog circuit modules such as reference voltage and power management, as well as digital signal processing circuits for processing electrical parameters such as active power and effective values of current and voltage. Using the BL0942 type energy metering chip U50 for power grid data acquisition can achieve high-precision real-time monitoring of parameters such as power grid voltage, current, active power, reactive power, power factor, and energy. It has the advantages of strong anti-interference ability, fast response speed, and high integration, which helps to improve the accuracy and reliability of power grid energy efficiency management and provides stable and accurate data support for scenarios such as smart meters, electricity monitoring, and load analysis, thereby achieving comprehensive optimization of the power usage status. The isolation module uses a π122U31 type digital isolation chip U49, which can realize electrical isolation between the main control module and the power grid data acquisition module and ensure the integrity of signal transmission. It can effectively prevent interference or damage to the main control module from the high voltage side, and improve the anti-interference capability and safety of the system. At the same time, the chip supports high-speed, low-latency data communication, ensuring the accuracy and real-time performance of metering data during isolated transmission, thereby enhancing the overall stability and reliability of the system.
[0052] In this embodiment, the energy storage lighting control system further includes a communication module, which is connected to the main control module. In this embodiment, the communication module employs any one or any combination of a 4G (fourth-generation mobile communication) module, a Zigbee module, and a GPRS (General Packet Radio Service) transceiver module.

[0053] In this embodiment, as Figure 10 The circuit diagram shows a third power conversion module that performs DC / DC step-down conversion on the power supply voltage of the energy storage module. It can convert the output voltage of the energy storage module into a +12V voltage that can charge the backup battery and a 3.3V voltage that can be used by the main control module, thereby providing power support to the main control module and other modules.
[0054] This embodiment enables coordinated switching between energy storage power supply and mains power supply, improving energy utilization efficiency and operational economy. Specifically, during implementation, this embodiment achieves dynamic switching control between the energy storage path and the mains power path by setting up a main control module, a boost drive module, an energy storage module, a dual-path power conversion module (composed of a first power conversion module and a second power conversion module), and a lighting module.
